All of the sales, and deductions taken above, shall be determined in accordance with GAAP.

Any disposal of Licensed Products for, or use of Licensed Products in, clinical or pre-clinical trials, given as free samples, including, without limitation, sample cards, or distributed for indigent programs shall not be included in Net Sales.

Upon any sale or other disposal of any Licensed Product that should be included within Net Sales for any consideration other than an exclusively monetary consideration on bona fide arm’s- length terms, then for purposes of calculating the Net Sales under this Agreement, such Licensed Product shall be deemed to be sold exclusively for money at the average sales price during the applicable reporting period generally achieved for such Licensed Product in the country in which such sale or other disposal occurred when such Licensed Product is sold alone and not with other products.

If, on a country-by-country basis, the Active Component(s) in the Combination Product is not sold separately in said country, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/D, where A is the invoice price of the Licensed Product (which does not contain any Active Component(s)), if sold separately, and D is the invoice price of the Combination Product. If neither the Licensed Product (which does not contain any Active Component(s)) nor the Active Component(s) in the Combination Product is sold separately in a given country, the Parties shall determine Net Sales for such Combination Product by mutual agreement based on the relative contribution of the Licensed Product (which does not contain any Active Component(s)) and the Active Components in the Combination Product.

In the event a Licensed Product is sold with one or more other products or services for a single price (together, a “Multiple Product Offering”), Net Sales for such Multiple Product Offering shall be calculated by multiplying actual Net Sales of such Multiple Product Offering by the fraction A/(A+B) where A is the invoice price of the Licensed Product, if sold separately, and B is the total invoice price of the other products in the Multiple Product Offering, if sold separately. If, on a country-by-country basis, the other products in the Multiple Product Offering are not sold separately in said country, Net Sales for the purpose of determining royalties of the Multiple Product Offering shall be calculated by multiplying actual Net Sales of such Multiple Product Offering by the fraction A/D, where A is the invoice price of the Licensed Product, if sold separately, and D is the invoice price of the Multiple Product Offering. If neither the Licensed Product nor the other products are sold separately in a given country, the Parties shall determine Net Sales for such Multiple Product Offering by mutual agreement based on the relative contribution of the Licensed Product (excluding other products) and each other product in the Multiple Product Offering.

(ii) if clause (i) above does not apply and a Valid Claim claiming such Licensed Product issues in such country or the Licensed Product is granted market exclusivity from a Regulatory Authority in such country after the date such Licensed Product received Regulatory Approval in such country, (A) Amylin shall pay to Amgen royalties on Net Sales of such Licensed Product in such country for the period from the Launch Date for such Licensed Product in such country through the date that such Valid Claim that claims such Licensed Product in such country issues or market exclusivity for such Licensed Product is granted by a Regulatory Authority in such country at a rate of [*] percent ([*]%), to be paid within forty-five (45) days of the date that such Valid Claim that claims such Licensed Product in such country issues or market exclusivity for such Licensed Product is granted by a Regulatory Authority in such country; and (B) Amylin shall pay royalties to Amgen on Net Sales of such Licensed Product in such country from the date such Valid Claim that claims such Licensed Product in such country issues or market exclusivity for such Licensed Product is granted by a Regulatory Authority in such country during the remaining Royalty Term for such Licensed Product at a rate of [*] percent ([*]%) (as may be reduced under Section 5.3(c)), to be paid within forty-five (45) days of the end of each calendar quarter for the preceding calendar quarter’s Net Sales; and

5.4 Third Party Royalties. If Amylin is required to pay royalties to one or more Third Parties greater than [*]% cumulatively (on an annual basis) on annual Net Sales of Licensed Products in any country (other than royalties due under the Rockefeller License) for a patent license required, in Amylin’s reasonable judgment, in order to sell such Licensed Products, [*]% of such royalties (meaning the royalties in excess of [*]%) actually paid by Amylin to such Third Parties (net of any offsets against royalties payable to such Third Party(ies), including The Rockefeller University) is creditable against royalties due to Amgen for such period, provided that the royalties due to Amgen in any calendar quarter shall not be reduced by more than [*]%. Such royalties in excess of [*]% of Net Sales cumulatively due to such Third Parties for a patent license in a particular country or territory shall be creditable only against the royalties due to Amgen hereunder on Net Sales in such country or territory. For the avoidance of doubt, royalties paid to a Third Party for a patent license as set forth in this Section 5.4 would qualify for this deduction only to the extent required and paid for Commercializing Licensed Products, and royalties required for access to broad technology platforms would not qualify.

5.5 Payments; Reports. Payment of all sums due hereunder shall be made to Amgen by wire transfer, or electronic funds transfer (EFT), in accordance with payment transfer instructions to be provided by Amgen. Beginning with the calendar quarter in which the Launch Date of the first Licensed Product occurs until the expiration of Amylin’s obligation to pay royalties, royalty payments and reports of the sale of Licensed Products for each calendar quarter will be calculated and delivered to Amgen under this Agreement within forty five (45) days of the end of each such calendar quarter, unless otherwise specifically provided herein. Each payment of royalties shall be accompanied by a report of Net Sales of Licensed Products in sufficient detail to permit confirmation of the accuracy of the royalty payment made, including and on a country-by-country basis, the number of Licensed Products sold, the gross sales and Net Sales of Licensed Products and deductions taken from gross sales by category as set forth in the definition of Net Sales to arrive at the Net Sales calculation, the royalties payable (in Dollars), the method used to calculate the royalty and the exchange rates used. The total royalty due for the sale of Licensed Products during such calendar quarter shall be paid at the time such report is made. Amylin will keep complete and accurate records pertaining to the sale or other disposition of Licensed Products in sufficient detail to permit Amgen to confirm the accuracy of all payments due hereunder.

5.6 Exchange Rate. With respect to Net Sales invoiced or expenses incurred in Dollars, the Net Sales or expense due to Amgen hereunder shall be expressed in Dollars. With respect to Net Sales invoiced or expenses incurred in a currency other than Dollars, the Net Sales invoiced or expenses incurred shall be converted into the Dollar equivalent using a rate of exchange which corresponds to the rate used by the invoicing or incurring Party, for the respective reporting period, related to recording such Net Sales or expenses in its books and records that are maintained in accordance with GAAP. All payments shall be made in Dollars. If at any time legal restrictions in any country in the Territory prevent the prompt remittance of any payments with respect to sales in that country, Amylin shall have the right and option upon written notice to Amgen to make such payments by depositing the amount thereof in local currency to Amgen’s account (or such other designated nominee by Amgen) in a bank or depository in such country.

5.7 Late Payments. Any undisputed amounts not paid by Amylin when due under this Agreement or disputed amounts that become subsequently due upon resolution of such dispute which are not paid by Amylin within fifteen (15) days of such resolution, shall be subject to interest from and including the date payment is due through and including the date upon which Amylin has made a wire transfer of immediately available funds into an account designated by Amgen, at a rate equal to LIBOR (London InterBank Offer Rate) plus [*] percent ([*]%).

5.8 Taxes. In the event that laws, rules or regulations require Amylin to withhold Taxes with respect to any payment to be made by Amylin pursuant to this Agreement, Amylin will notify Amgen of such withholding requirement prior to making the payment to Amgen and provide such assistance to Amgen, including the provision of such documentation as may be required by a tax authority, as may be reasonably necessary in Amgen’s efforts to claim an exemption from or reduction of such taxes. Amylin will, in accordance with such laws, rules or regulations, withhold taxes from the amount due, and remit such taxes to the appropriate tax authority. Amylin shall provide to Amgen original copies of all official receipts evidencing such tax obligation together with written evidence of payment within fifteen (15) days following such payment. If taxes are paid to a tax authority, Amylin shall provide reasonable assistance to Amgen to obtain a refund of taxes withheld, or obtain a credit with respect to taxes paid.

5.9 Audit. Amylin shall keep complete and accurate records of the underlying revenue and expense data relating to the calculations of Net Sales and payments required under this Agreement. Amgen shall have the right, at its own expense and no more than once per year, to have an independent, certified public accountant, selected by Amgen and reasonably acceptable to Amylin, review such records of Amylin upon reasonable notice (which shall be no less than thirty (30) days prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the basis and accuracy of payments required and made under this Agreement within the prior thirty-six (36) month period; provided that, if royalties are owed for retroactive periods pursuant to Section 5.3(b)(i) or (ii), then for a thirty-six (36) month period after the date such royalties first become due under Section 5.3(b)(i) or (ii), Amgen shall have the right to audit records related to the period of the Royalty Term prior to such date. No calendar year may be audited more than one time. Notwithstanding the foregoing, in the event that Amylin restates its earnings, and such restatement would impact the royalty due to Amgen for any period(s) previously audited, or Amylin revises a report or makes a further payment for a period for which a report or payment was previously provided or due to Amgen under Section 5.5, which report or payment reflects a material change in the amount of royalties due for the prior period and Amgen has previously audited such period, then Amgen shall have the right to re-audit the affected time period(s) solely with respect to verifying the effect, if any, such restatement or revision has on royalties due with respect to such period(s). Amylin shall receive a copy of each audit report promptly from Amgen. Should the inspection lead to the discovery of a discrepancy to Amgen’s detriment, Amylin shall pay the amount of the discrepancy within thirty (30) days after being notified

thereof. Amgen shall pay the full cost of the inspection unless the discrepancy is greater than [*] percent ([*]%), in which case Amylin shall pay to Amgen the reasonable cost charged by such accountant for such inspection.

Subject to the indemnification and defense obligations of the Parties under Article 8, each Party shall be responsible for defending, and shall control the defense of, any such action brought against such Party. The Parties shall confer with each other and cooperate in the defense of any such action in which both Amgen and Amylin are named parties.

ARTICLE 8

INDEMNIFICATION

8.1 Indemnification by Amgen. Amgen hereby agrees to defend, hold harmless and indemnify Amylin and its Affiliates, and each of their respective officers, directors and employees (collectively, the “Amylin Indemnitees”), from and against any and all Losses arising out of (i) any of Amgen’s representations and warranties set forth in Section 7.1 of this

Agreement being untrue in any material respect when made; (ii) Amgen’s failure to perform, in any material respect, any covenant or agreement of Amgen set forth in this Agreement; and (iii) Amgen’s gross negligence or willful misconduct; except, in each case, to the extent any such Losses result from the gross negligence or willful misconduct of Amylin Indemnitees or from the breach of any representation or warranty hereunder or of this Agreement by Amylin.

8.2 Indemnification by Amylin. Amylin hereby agrees to defend, hold harmless and indemnify Amgen and its Affiliates, and each of their respective officers, directors and employees (collectively, the “Amgen Indemnitees”), from and against any and all Losses arising out of (i) any of Amylin’s representations and warranties set forth in Section 7.2 of this Agreement being untrue in any material respect when made; (ii) Amylin’s failure to perform, in any material respect, any covenant or agreement of Amylin set forth in this Agreement; (iii) the practice by Amylin, its Affiliates or Sublicensees of the licenses granted to Amylin under Sections 2.1, 2.2 and 2.3; and (iv) the development, manufacture or Commercialization of Leptin and/or any Licensed Product by or for Amylin, its Affiliates or Sublicensees; except, in each case, to the extent any such Losses result from the gross negligence or willful misconduct of Amgen Indemnitees or from the breach of any representation or warranty hereunder or of this Agreement by Amgen.

8.3 Indemnification Procedures. Each Party (Amgen on behalf of Amgen Indemnitees, or Amylin on behalf of Amylin Indemnitees) will promptly notify the other Party when it becomes aware of a claim for which indemnification may be sought hereunder (a “Claim”). To be eligible to be indemnified for a Claim, a Person seeking indemnification (the “Indemnified Party”) shall (i) provide the Party required to indemnify such Person (the “Indemnifying Party”) with prompt written notice of the Claim giving rise to the indemnification obligation under this Article 8, provided that, the failure to provide such prompt notice shall not relieve the Indemnifying Party of any of its obligations under this Article 8 except to the extent the Indemnifying Party is actually prejudiced thereby; (ii) provide the Indemnifying Party with the exclusive ability to defend (with the reasonable cooperation of the Indemnified Party) against the Claim; and (iii) not settle, admit or materially prejudice the Claim, without the Indemnifying Party’s prior written consent. The Indemnified Party shall reasonably cooperate with the Indemnifying Party, at the Indemnifying Party’s expense, in the defense of any Claim. Notwithstanding the foregoing, the Indemnified Party shall have the right to participate in and have its own counsel participate in any action or proceeding for which the Indemnified Party seeks to be indemnified by the Indemnifying Party. Such participation shall be at the Indemnified Party’s expense, unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Indemnifying Party’s obligations under Section 8.1 or 8.2, as the case may be, shall not apply to the extent of the Indemnified Party’s failure to take reasonable action to mitigate any Losses.

Such insurance shall not be construed to create a limit of Amylin’s liability with respect to its indemnification obligations under this Article 8. Amylin shall provide Amgen with written evidence of such insurance upon request. Amylin shall provide Amgen with prompt written notice of cancellation, non-renewal or material change in such insurance or self-insurance which could materially adversely affect the rights of Amgen hereunder and shall use commercially reasonable efforts to provide such notice at least thirty (30) days prior to any such cancellation, non-renewal or material change.

Information, and agrees to (i) maintain in confidence Manufacturing Information with the same degree of care that Amylin uses to protect its own like information, (ii) strictly limit access to and use of Manufacturing Information to employees, representatives, consultants and contractors of Amylin and the CMO(s) with a need to know such information, and (iii) use Manufacturing Information and trade secrets only for producing Licensed Product(s) in the Product Field, Amylin shall ensure that any Person having access to the Manufacturing Information will be made aware of its highly confidential nature and will agree to be bound by confidentiality terms no less stringent than those in this Agreement. Amgen agrees to maintain in confidence Manufacturing Information as it relates to A-100 Leptin and A-200 Leptin with the same degree of care that Amgen uses to protect its own like information. The obligations under this Section 9.2 shall survive and continue in effect for a period of twenty (20) years following any expiration or termination of this Agreement. Each of Amgen and Amylin acknowledge and agree that Confidential Information disclosed to the CMO selected hereunder, and any Confidential Information of the other Party received from such CMO, shall not cause such Confidential Information to fall within any exceptions within the definition of Confidential Information herein or otherwise cease to be Confidential Information of the applicable Party.

9.3 Authorized Disclosure. If, based upon the advice of legal counsel skilled in the subject matter, a Party is required to disclose Confidential Information of the other Party to comply with an applicable law, regulation, legal process, or order of a government authority or court of competent jurisdiction, the Party may disclose such Confidential Information only to the Person required to receive such disclosure; provided, however, that the Party required to disclose such Confidential Information shall (a) to the extent permitted by such law, regulation, process, order or rules, first have given prompt (but in no event less than five (5) business days) advance notice to such other Party to enable it to seek any available exemptions from or limitations on such disclosure requirement and shall reasonably cooperate in such efforts by the other Party, (b) furnish only the portion of the Confidential Information which is legally required; (c) use all reasonable efforts to secure confidential protection of such Confidential Information, and (d) continue to perform its obligations of confidentiality set out herein. Each Party may disclose Confidential Information of the other Party to Regulatory Authorities to the extent such disclosure is reasonably necessary in regulatory filings required for the development and/or commercialization of Licensed Products. In addition, each Party may disclose Confidential Information of the other Party (other than Manufacturing Information) to the extent such disclosure is reasonably necessary in the following instances: filing or prosecuting patents as permitted by this Agreement; disclosure to The Rockefeller University and The Regents of the University of California to the extent necessary to fulfill obligations under the Rockefeller License and UCSF License, respectively, in accordance with this Agreement and the Rockefeller License or the UCSF License, as applicable; and disclosure to Sublicensees and potential Sublicensees, contractors, employees and consultants who need to know such information for the development, manufacture and commercialization of Licensed Products, to bankers, lawyers, accountants, agents or other Third Parties in connection with due diligence or similar investigations, and to potential Third Party investors in confidential financing documents; provided that any such Sublicensee, contractor, employee, consultant, banker, lawyer, accountant, agent or Third Party is bound by obligations of confidentiality and non-use at least as

restrictive as those set forth herein. In the case of each disclosure, the Party making such disclosure shall use reasonable efforts to obtain confidential treatment of any such disclosure, and shall not disclose Confidential Information of the other Party other than is reasonably necessary.

9.4 Publicity; Terms of Agreement. The Parties shall treat the existence and material terms of this Agreement as confidential and shall not disclose such information to Third Parties without the prior written consent of the other Party or except as provided in Section 9.3 (treating such information as Confidential Information for purposes of Section 9.3). The Parties agree that upon execution of this Agreement or shortly thereafter, either Party may issue a press release, which shall be subject to prior review and approval by the other Party, not to be unreasonably withheld or delayed. Except for such press release or as otherwise required by applicable law or applicable stock exchange requirements, neither Amgen nor Amylin shall issue or cause the publication of any other press release or public announcement with respect to the transactions contemplated by this Agreement without the express prior approval of the other Party, which approval shall not be unreasonably withheld or delayed; provided that, each of Amgen and Amylin may make any public statement in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst calls, or issue press releases, so long as any such public statement or press release is not inconsistent with prior public disclosures or public statements approved by the other Party pursuant to this Section 9.4 and which do not reveal non-public information about the other Party. If, in the reasonable opinion of a Party’s legal counsel, a public announcement of the transactions contemplated by the Agreement is required by applicable laws or applicable stock exchange requirements, then, to the extent permissible by law, such Party will provide the other with notice reasonable under the circumstances (but in no event less than ten (10) days prior to disclosure) of such intended announcement and will consult with the other Party with respect to the nature and scope of the required announcement (which shall be limited to the information reasonably required to be disclosed). In addition to the foregoing, with respect to complying with the disclosure requirements of the Securities and Exchange Commission or other regulatory agencies, in connection with any required filing of this Agreement with such agency, the Parties shall consult with one another concerning which terms of this Agreement shall be requested to be redacted in any public disclosure of the Agreement by the agency, and each Party shall seek confidential treatment by the agency in public disclosure of the Agreement by the agency for the definitions of Leptin, Licensed Products and Neuro Field, the exhibits, and any dollar amounts set forth herein.

9.5 Injunctive Relief. Given the nature of the Confidential Information and the competitive damage that would result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 9. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 9.

Notwithstanding the foregoing, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any patent right shall be submitted exclusively to the competent court having jurisdiction over the disputed patent.

11.4 Interpretation. Amgen and Amylin have each participated in negotiations and due diligence and consulted their respective counsel regarding this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

EXCHANGE COMMISSION.

 

any business transaction, change in control of a majority of the voting power or other event that, in each case, causes such Affiliate to cease to be an Affiliate of the Party, shall be deemed an assignment of the rights and/or obligations held by such former Affiliate and require prior written consent of the other Party. Notwithstanding the foregoing, Amgen shall have the right to assign its rights to payment pursuant to Article 5 without Amylin’s consent. This Agreement shall be binding on the successors and permitted assigns of the assigning Party, and the name of a Party appearing herein shall be deemed to include the name(s) of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement. Any assignment or attempted assignment by either Party in violation of the terms of this Section 11.5 shall be null and void and of no legal effect.

11.6 Performance by Affiliates. Each of Amgen and Amylin acknowledge that obligations under this Agreement may be performed by Affiliates of Amgen and Amylin. Each of Amgen and Amylin guarantee performance of this Agreement by its Affiliates, notwithstanding any assignment to Affiliates in accordance with Section 11.5 of this Agreement.

11.12 No Waiver. A Party’s consent to or waiver, express or implied, of the other Party’s breach of its obligations hereunder shall not be deemed to be or construed as a consent to or waiver of any other breach of the same or any other obligations of the other Party. A Party’s failure to complain of any act, or failure to act, by the other Party, to declare the other Party in default, to insist upon the strict performance of any obligation or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof, no matter how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder, of any such breach, or of any other obligation or condition. A Party’s consent in any one instance shall not limit or waive the necessity to obtain such Party’s consent in any future instance and in any event no consent or waiver shall be effective for any purpose hereunder unless such consent or waiver is in writing and signed by the Party granting such consent or waiver.

WITNESSETH:

WHEREAS, Rockefeller and Amgen have entered into a License Agreement dated April 14, 1995, as amended and supplemented by a letter agreement dated May 10, 1995 (the “License Agreement”).

WHEREAS, Rockefeller and Amgen now wish to further amend certain terms and conditions set forth in the License Agreement.

NOW THEREFORE, in consideration of the foregoing and the covenants and promises contained in this Amendment, the Parties agree as follows:

1. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the License Agreement.

2. Section 1 of the License Agreement shall be amended to add (or in the case of the definition for “NDA”, such definition shall be deleted in its entirety and shall be superseded and replaced by the definition for “NDA” set forth hereinbelow) the following definitions:

BLA” shall mean a Biological License Application and all amendments and supplements thereto submitted to the FDA.

THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

(i) If an NDA or BLA is submitted to the FDA for a Product for any indication within eighteen (18) months from the Amendment Date, the following milestones shall apply to such Product and all subsequent Products (and the milestones in Subparagraphs 6.1(b)(ii) and (iii) shall not apply):

 

Milestone Event

   Milestone Payment

[*]

  
  
  
  
  

(ii) If an NDA or BLA is submitted to the FDA for a Product for any indication following the eighteenth (18th) month alter the Amendment Date, but before or during the forty second (42nd) month after the Amendment Date (and Subparagraph 6.l(b)(i) does not apply), the following milestones shall apply to such Product and all subsequent Products (and the milestones in Subparagraphs 6.l(b)(i) and (iii) shall not apply):

 

Milestone Event

   Milestone Payment

[*]

  
  
  
  
  

(iii) If an NDA or BLA is submitted to the FDA for a Product for any indication after the forty second (42nd) month after the Amendment Date but before or during the sixtieth (60th) month after the Amendment Date (and neither Subparagraph 6.1(b)(i) nor (ii) apply), the following milestones shall apply (and the milestones in Subparagraphs 6.i(b)(i) and (ii) shall not apply):

THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

For the avoidance of doubt, payment of any of the foregoing milestones set forth in Subparagraphs 6.1(b)(i), (ii) or (ill) shall be made only once for the first achievement of such milestone, and not with respect to each additional occasion that such milestone is achieved. Also, for purposes of the milestones set forth in Subparagraphs 6.l(b)(ii) and (iii), a Phase III Licensing Trial shall be deemed initiated upon enrollment of the first patient therefor. For purposes of Subparagraph 6.1, an NDA or BLA shall not require inclusion, of the CMC (Chemistry, Manufacturing and Controls) section to be deemed submitted to the FDA.

Notwithstanding anything in this Agreement to the contrary, to the extent the initiation of the first Phase III Licensing Trial for the first Orphan Product indication of a Product other than SLD, or the first non-Orphan Product indication of a Product other than SLD, occurs prior to the end of the forty-second (42nd) month after the Amendment Date and prior to Amgen or its sublicensee first submitting an NDA or BLA to the FDA for a Product for any indication, the applicable milestone payment under Subparagraph 6.1(b)(ii)(A) or (B) shall be paid to Rockefeller within thirty (30) days following first achievement by Amgen or its sublicensee of such Phase III Licensing Trial milestone event; provided, however, that if the first Phase III Licensing Trial for the first Orphan Product indication of a Product other than SLD, or the first non-Orphan Product indication of a Product other than SLD, occurs (i) within eighteen (18) months of the Amendment Date; and (ii) neither Amgen nor its sublicensee has first submitted an NDA or BLA to the FDA for a Product for any indication within eighteen (18) months after the Amendment Date, the applicable milestone payment under Subparagraph 6.1(b)(ii)(A) or (B) shall be paid to Rockefeller within thirty (30) days of the first day of the nineteenth (19th) month after the Amendment Date. Upon Amgen or its sublicensee first submitting an NDA or BLA to the FDA for a Product for any indication, to the extent that the timing of the filing results in a higher milestone payment (as set forth in Subparagraph 6.1(b)(iii)(A) or (B)) being due Rockefeller for the achievement of a prior milestone (e.g., a milestone payment has been made under Subparagraph 6.1(b)(ii)(A), but the timing of Amgen’s first submission of an NDA or


THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

BLA to the FDA for a Product occurs after the forty-second (42nd) month after the Amendment Dale such that the milestones of Subparagraph 6.1(b)(iii) apply), Amgen shall pay to Rockefeller such difference within thirty (30) days of Amgen or its sublicensee first submitting such NDA or BLA to the FDA for a Product for any indication. By way of example, and not as a limitation, if Amgen initiates the first Phase III Licensing Trial for the first Orphan Product indication of a Product other than for SLD prior to first submitting an NDA or BLA to the FDA for a Product for any indication (and Subparagraph 6.1(b)(i) does not apply), Amgen shall pay to Rockefeller [*] in accordance with Subparagraph 6.1(b)(ii)(A); and then if Amgen first submits an NDA or BLA to the FDA for a Product for any indication after the forty second (42nd) month after the Amendment Date, Amgen shall pay Rockefeller an additional [*], which is the difference between the [*] initially paid to Rockefeller upon initiation of the first Phase III Licensing Trial for the first Orphan Product indication of a Product other than for SLD under Subparagraph 6.1(b)(ii)(A), and the [*] milestone payment due Rockefeller under Subparagraph 6.1(b)(iii)(A).

4. Subparagraph 6.1 of the License Agreement shall be amended to add the following:

(f) an NDA or BLA is submitted to the FDA by Amgen or its sublicensee within eighteen (18) months of the Amendment Date for a Product for SLD, then for each year for the term of this Agreement, the royalties shall be calculated pursuant to this Subparagraph 6.1(f) rather than Subparagraph 6.1(c). Amgen shall pay royalties on Patented Products at the rate of [*] percent ([*]%) for the first [*] in annual Net Sales. For any additional annual Net Sales, the royalty rates in Subparagraph 6.1(c) of this Agreement shall apply (and for the avoidance of doubt, the first [*] in annual Net Sales set forth in the preceding sentence shall not be subject to such royalty rates; thus the first Dollar of annual Net Sales after the first [*] in annual Net Sales shall be considered the first Dollar of annual Net Sales for purposes of determining the applicable annual Net Sales threshold in Subparagraph 6.l(c)(i), (ii) and (iii)). By way of example and not as a limitation, if Amgen achieved [*] in annual Net Sales for a Patented Product, the royalty rates applicable to such annual Net Sales would be a [*] percent ([*]%) royalty on the first [*], a [*] percent ([*]%) royalty on the next [*] (which is that portion of total annual Net Sales between [*] and [*], and a [*] percent ([*]%) royalty on [*], which is the balance of the annual Net Sales.

(g) If an NDA or BLA is submitted to the FDA by Amgen or its sublicensee after the forty second (42nd) month following the Amendment Date but before or during the sixtieth (60th) month after the Amendment Date for a Product for any indication (and an NDA or BLA has not been submitted to the FDA by Amgen or its sublicensee prior to or during the forty second (42nd) month following the Amendment Date for a Product for any indication), then for each year for the term of this Agreement, the royalties shall be calculated pursuant to this Subparagraph 6.1(g) rather than Subparagraph 6.1(c). Amgen shall pay royalties on Patented Products at the rate of [*] percent ([*]%) for the first [*] in cumulative Net Sales. Thereafter, for all additional Net Sales in the year in which [*] cumulative Net Sales is achieved and for all Net Sales in all subsequent years, the royalty rates in Subparagraph 6.1(c) of this Agreement shall apply (and for the avoidance of doubt, the first [*] in cumulative Net Sales set forth in the preceding sentence, shall not be subject to such royalty rates; thus all annual Net Sales in excess of the first [*] in cumulative Net Sales would be subject to the royalty rates set forth in Subparagraph 6.1(c) from

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

the first Dollar after the first [*] in cumulative Net Sales). By way of example and not as a limitation, if this Subparagraph 6.1(g) applies and Amgen achieves [*] in cumulative Net Sales for a Patented Product on March 31, 2009 (to which the foregoing [*] percent ([*]%) royalty would apply), and from April 1, 2009 to December 31, 2009, Amgen achieves Net Sales in the amount of [*], the royalty rates applicable to the Net Sales occurring from April 1, 2009 to December 31, 2009 would be a [*] percent ([*]%) royalty on [*] of such Net Sales, and a [*] percent ([*]%) royalty on the remaining [*] of such Net Sale.

(h) If no NDA or BLA has been submitted to the FDA by Amgen or its sublicensee by the fifth (5th) anniversary of the Amendment Date, Amgen or its sublicensee shall pay to Rockefeller [*] annually as a maintenance fee until an NDA or BLA has been submitted to the FDA by Amgen or its sublicensee for a Product for any indication, and Amgen or its sublicensee shall be subject to (on a prospective basis only) all unpaid original milestones described in Paragraph 6.1(b) of the License Agreement as in effect prior to the Amendment Date.

5. Subparagraph 6.5 of the License Agreement shall be amended in its entirety as follows:

6.5 Rockefeller agrees to use reasonable efforts, short of litigation, to resist any claim by a third party which might affect the exclusive nature of any license granted hereunder. In the event that during the term of this Agreement the license granted herein is rendered non-exclusive in any country of the Territory as a result of any governmental, judicial or other action, then the royalty provided in Subparagraph 6.1(c), (d), (e), (f) or (g) hereof due to Rockefeller from Amgen (and its sublicensees) on the affected Products) in that country shall be reduced by [*]. Amgen’s obligation to pay to Rockefeller a royalty on the affected Product pursuant to Subparagraph 6.1(c), (d), (e), (f) or (g) in that country shall expire/terminate no later than six (6) years (in the case of Subparagraph 6.1(c), (d), (f) or (g)) or five (5) years (in the case of Subparagraph 6.1(e)) from the date of first commercial sale of the affected Products) in that country. Thereafter, Amgen shall have a fully paid-up and perpetual license to make, use, and sell the affected Product(s) in that country.

6. Subpargraphs 6.9 and 6.10 are hereby added to the License Agreement as follows:

6.9 Sublicense Revenues. Within thirty (30) days of the date upon which any upfront license fees and other lump sum or one-time fees in consideration of a sublicense to the Licensed Patent Rights and Technical Information are paid to Amgen (including without limitation any other fee or payment for a sublicense to the Licensed Patent Rights and Technical Information which is paid to Amgen solely on the basis of the passage of time), Amgen shall pay to Rockefeller [*] percent ([*]%) of such amounts in accordance with Paragraph 9. To the extent that upfront license fees and other lump sum or one-time fees in consideration of a sublicense to the licensed Patent Rights and Technical Information are paid to Amgen in the form of equity securities, Amgen shall transfer, or cause to be issued to Rockefeller, [*] percent ([*]%) of the equity securities received by (or that would otherwise be issued to) Amgen, subject to applicable securities laws and other laws. As a condition to receiving such equity securities, Rockefeller acknowledges that it

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

EXCHANGE COMMISSION.

 

may be required to execute certain typical and customary agreements relating to the purchase and sale of such securities, which agreements may require certain representations by Rockefeller and impose certain obligations on Rockefeller related to, among other things, registration, lock-ups, co-sale, first refusal, first offer and voting rights, if any, relating to such equity securities. The parties acknowledge and agree that Amgen, its affiliates, subsidiaries and agents shall have no liability whatsoever with respect to the equity securities transferred or issued to Rockefeller, including without limitation, any liability related to the value, liquidity, volatility, rights, preferences or any other aspect of such securities. For the avoidance of doubt, any milestone or other payments tied to future clinical, regulatory, operational or commercial outcomes or sales shall not be considered sublicense revenues for purpose of this Subparagraph 6.9, and shall be excluded from such amounts.

6.10 No Other Compensation. Other than as explicitly set forth (and as applicable) in this Section 6, and Subparagraph 5.2, Section 7 and Section 11, Amgen shall not be obligated to pay any additional fees, milestone payments, royalties or any other payments to Rockefeller regarding the Licensed Patent Rights and Technical Information.

8. Subparagraph 19.3 of the License Agreement shall be amended in its entirety as follows:

19.3 Upon any termination of this Agreement, any sublicense(s) granted by Amgen prior to termination of this Agreement shall remain in full force and effect, provided that (i) the sublicensee is not then in material breach of its sublicense agreement, and (ii) upon Rockefeller’s written request to the sublicensee, the sublicensee agrees in writing within thirty (30) days of receipt of such request, to be bound as licensee under the terms and conditions of this Agreement.

SECOND AMENDMENT TO LICENSE AGREEMENT

This SECOND AMENDMENT TO LICENSE AGREEMENT (this “Amendment”) dated as of January 15, 2008 (“Amendment Date”) is entered into by and between The Rockefeller University, an education corporation organized and existing under the laws of the State of New York, with principal offices located at 1230 York Avenue, New York, New York 10021-6399 (“Rockefeller”), and Amgen Inc., a Delaware corporation ‘with principal offices located at One Amgen Center Drive, Thousand Oaks, California 91320-1799 (“Amgen”).

WITNESSETH:

WHEREAS, Rockefeller and Amgen have entered into a License Agreement dated April 13, 1995, as amended and supplemented by a letter agreement dated May 10,1995 and an Amendment dated January 1, 2006 (the “License Agreement”);

WHEREAS, Rockefeller and Amgen now wish to further amend certain terms and conditions set forth in the License Agreement;

NOW, THEREFORE, in consideration of the foregoing and the covenants and promises contained in this Amendment, the Parties agree as follows:

1. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the License Agreement.

2. Section 1 of the License Agreement shall be amended to add the following definitions:

“Active Component” shall mean any active pharmaceutical ingredient other than the Product which performs an identifiable therapeutic or prophylactic function when combined with the Product, and which is not disclosed or enabled under the Licensed Patent Rights.

“Combination Product” means any product sold by or on behalf of Amgen, its Affiliates or Sublicensee(s) which contains the Product in combination with one or more Active Components. For avoidance of doubt, Combination Products are a subset of Products.

3. Section 1.11 of the License Agreement shall be deleted and replaced in its entirety with the following:

“1.11 “Net Sales” shall mean all revenues, recognized in accordance with generally accepted accounting principles consistently applied, received from sales or other dispositions by Amgen, or a sublicensee of Amgen, to a third party, less returns and allowances (actually paid or allowed, including, but not limited to, prompt payment and volume discounts, chargebacks from

wholesalers and other allowances granted to customers or wholesalers, whether in cash or trade), bad debt, freight, shipping, packing, insurance, rebates, and sales and other taxes based on sales prices when included in gross sales, but not including taxes when assessed on income derived from such sales.

In the case of a Product that is a Combination Product, Net Sales for such Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/(A+B) where A is the invoice price of the Product which does not contain any Active Component(s), if sold separately, and B is the total invoice price of the Active Component(s) in the Combination Product, if sold separately. If, on a country-by-country basis, the Active Component(s) in the Combination Product is not sold separately in said country, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/D, where A is the invoice price of the Product which does not contain any Active Component(s), if sold separately, and D is the invoice price of the Combination Product. If neither the Product which does not contain any Active Component(s), nor the Active Component(s) in the Combination Product is sold separately in a given country, the Parties shall determine Net Sales for such Combination Product by mutual agreement based on the relative contribution of the Product which does not contain any Active Component(s) and the Active Components in the Combination Product; provided, however that if the parties are not able to mutually agree on the relative contribution of a Product which does not contain any Active Component(s) and the Active Component(s) in the Combination Product, then Net Sales for such Combination Product containing only one Active Component shall be fifty percent (50%) of the amount calculated in accordance with the first paragraph of this Section 1.11.

In the event a Product is sold with one or more other products or services for a single price (together, a “Multiple Product Offering”), Net Sales for such Multiple Product Offering shall be calculated by multiplying actual Net Sales of such Multiple Product Offering by the fraction A/(A+B) where A is the invoice price of the Product, if sold separately, and B is the total invoice price of the other products or services in the Multiple Product Offering, if sold separately. If, on a country-by-country basis, the other products or services in the Multiple Product Offering are not sold separately in said country, Net Sales for the purpose of determining royalties of the Multiple Product Offering shall be calculated by multiplying actual Net Sales of such Multiple Product Offering by the fraction A/D, where A is the invoice price of the Product, if sold separately, and D is the invoice price of the Multiple Product Offering. If neither the Product nor the other products or services are sold separately in a given country, the Parties shall determine Net Sales for such Multiple Product Offering by mutual agreement based on the relative contribution of the Product (excluding

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

other products) and each other product or service in the Multiple Product Offering; provided, however that if the parties are not able to mutually agree on the relative contribution of the Product (excluding other products) and each other product or service in the Multiple Product Offering, then Net Sales for such Multiple Product Offering containing only one other product or service shall be fifty percent (50%) of the amount calculated in accordance with the first paragraph of this Section 1.11.

For purposes of the two preceding paragraphs, the invoice price of the Product (which does not contain any Active Component(s)) sold separately for an indication designated as an “Orphan Product” under the U.S. Orphan Drug Act, as amended, shall not be used to calculate Net Sales for any Combination Product or Multiple Product Offering, except any such Combination Product or Multiple Product Offering that is used for an indication designated as an “Orphan Product” under the U.S. Orphan Drug Act, as amended.”

4. For the purposes of Section 6.1(e) of the License Agreement, a Know-How Product shall include any product, the selling of which would, in the absence of this Agreement, infringe a claim in an issued but expired patent included within the Licensed Patent Rights in the country in which the product is sold by Amgen or a sublicensee thereof, provided, however, that notwithstanding anything to the contrary set forth in the License Agreement, Amgen shall not be required to pay royalties for such Know-How Product for more than five (5) years including years of royalties paid for the same product pursuant to Section 6.1(c) or (d) of the License Agreement. However, if that certain License Agreement by and between Amgen and Amylin Pharmaceuticals, Inc. effective as of the 7th day of February 2006 expires or terminates during the term of the License Agreement, then any Know-How Product royalty payable to Rockefeller shall be governed by the original language in Section 6.1(e) of the License Agreement as in effect prior to the Amendment Date (rather than the amended language set forth in this Section 4 of this Amendment).

5. Section 6.9 of the License Agreement shall be deleted and replaced in its entirety with the following:

“6.9 Sublicense Revenues. Within thirty (30) days of the date upon which any upfront license fees and other lump sum or one-time fees in consideration of a sublicense to the Licensed Patent Rights and Technical Information are paid to Amgen or its sublicensee (including without limitation any other fee or payment for a sublicense to the Licensed Patent Rights and Technical Information which is paid to Amgen or its sublicensee solely on the basis of the passage of time), Amgen or its sublicensee shall pay to Rockefeller [*] percent ([*]%) of such amounts in accordance with Paragraph 9. To the extent that upfront license fees and other lump sum or one-time fees in consideration of a sublicense to the Licensed Patent Rights and Technical Information are paid to Amgen or its sublicensee in the form of equity securities, Amgen or its sublicensee shall transfer, or cause to be issued to Rockefeller, [*] percent ([*]%) of the equity

securities received by (or that would otherwise be issued to) Amgen or its sublicensee, subject to applicable securities laws and other laws. As a condition to receiving such equity securities, Rockefeller acknowledges that it may be required to execute certain typical and customary agreements relating to the purchase and sale of such securities, which agreements may require certain representations by Rockefeller and impose certain obligations on Rockefeller related to, among other things, registration, lock-ups, co-sale, first refusal, first offer and voting rights, if any, relating to such equity securities. The parties acknowledge and agree that Amgen, its sublicensees and their respective affiliates, subsidiaries and agents shall have no liability whatsoever with respect to the equity securities transferred or issued to Rockefeller, including without limitation, any liability related to the value, liquidity, volatility, rights, preferences or any other aspect of such securities. For the avoidance of doubt, any milestone or other payments tied to future clinical, regulatory, operational or commercial outcomes or sales shall not be considered sublicense revenues for purpose of this Subparagraph 6.9, and shall be excluded from such amounts. If any upfront license fees and other lump sum or one-time fees are paid to Amgen or its sublicensee in consideration of a sublicense to the Licensed Patent Rights and Technical Information as well as other intellectual property not subject to the License Agreement, the payment to Rockefeller pursuant to this Section 6.9 shall be reduced based on the relative contribution of the Licensed Patent Rights and Technical Information, on the one hand, and the other intellectual property not subject to the License Agreement, on the other hand; provided, however that if the parties are not able to mutually agree on the relative contribution of the Licensed Patent Rights and Technical Information, on the one hand, and the other intellectual property not subject to the License Agreement, on the other hand, then the payment to Rockefeller pursuant to this Section 6.9 shall be determined based on an equal contribution of the Licensed Patent Rights and Technical Information, on the one hand, and each other category of intellectual property not subject to the License Agreement, on the other hand.”

6. Except as amended and supplemented hereby, all of the terms of the License Agreement, as amended and supplemented to date, shall remain and continue in full force and effect.

7. This Amendment may be executed in any number of counterparts, each of which need not contain the signature of more than one Party, but all such counterparts taken together shall constitute one and the same document.

8. Whenever possible, each provision of this Amendment will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Amendment.

9. No amendment, modification or supplement of any provision of this Amendment shall be valid or effective unless made in writing and signed by a duly authorized officer of each Party.

10. This Amendment and the License Agreement constitute and contain the complete, final and exclusive understanding and agreement of the Parties with respect to the subject matter hereof and thereof, and cancel and supersede any and all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties, respecting the subject matter hereof and thereof.

11. Notwithstanding anything in the License Agreement to the contrary, Rockefeller acknowledges and agrees that Amgen may disclose the terms of the License Agreement and this Amendment and Confidential Information of Rockefeller disclosed to Amgen under the License Agreement and this Amendment, to potential and existing sublicensees of the Licensed Patent Rights and Technical Information under confidentiality obligations no less restrictive than those Amgen requires of parties to whom it may disclose its own confidential information.

Description

 

This application claims priority under 35 U.S.C. l19(C) to provisional application 60/006,106, filed Oct. 25, 1995.

BACKGROUND OF THE INVENTION

The sterility of male and female homozygous ob/ob mice was recognized since the original report of the ob mutation (Ingalls et al. J. Hered. 41:317-318 (1950)). ob/ob females are always sterile whereas ob/ob males can occasionally become fertile if maintained on a restricted diet (Lane et al. J. Heredity 45:56-58 (1954)). The ovaries of ob/ob females are capable of producing viable eggs when transplanted into lean female recipients (Hummel et al. Anat. Rec. 128:569 (1957)). Although early sexual development is normal, ovulation never follows and the mice remain prepuberal indefinitely. FSH, LH and testosterone levels are reduced in ob/ob females (Swerdloff et al. Endocrinology 98:1359-1364 (1976)), demonstrating the absence of a functional feedback from the hypothalamic-pituitary axis. Hypofunction of the pituitary gland in the female ob/ob mouse was demonstrated indirectly by showing that their in vivo uterine weights did not significantly change after bilateral ovariectomy (Runner et al. Genetics 39:990-991 (1954); Drasher et al. J. Heredity 46:209-212 (1955)) but did, however, respond to exogenous estrogen. Pituitary extracts administered to ob/ob females induced ovulation and conception, but not implantation (Runner, M. N. Rec. Genet. Soc. Am. 23:63-64 (1954)) which was achieved following treatment with gonadotropic hormones (Runner et al. J. Heredity 45:51-55 (1954)). Furthermore, the administration of high doses of progesterone maintained pregnancy for 19 days p.c., but did not enable the mothers to deliver the fetuses except after administration of relaxin which stimulated parturition and lactation (Smithberg et al. J. Exp. Zool. 133:441-458 (1956); Smithberg et al. J. Heredity 48:97-100 (1957)). The above findings demonstrated that the sterility of the ob/ob female is caused by an insufficiency of hormones at the hypothalamic-pituitary level rather than physical hindrance of copulatory activity by excess adipose tissue.

Kennedy and Mitra (J. Physiol. (London) 166:408 (1963)) proposed that puberty is linked to body weight and more specifically to fat storage which is as they conclude, one of the signals responsible for the initiation of hypothalamic control of ovarian function. Frisch and McArthur (Science 185:949 (1974)) related the loss or restoration of menstrual cycles in young girls to a minimum weight for height and reported that normal girls become relatively fatter from menarche to reproductive maturity. Therefore, these early and important findings established a relationship between initiation of reproduction and adiposity. In support of this relationship were the observations that very lean young female ballet dancers and college rowers (Frisch et al. NEJM 303:17 (1980); Frisch et al. JAMA 246:1559 (1981)) have delayed puberty, whereas obese girls have an acceleration of puberty (Zacharias et al. Am. J. Obs. Gyn. 108:833 (1970)). Furthermore, the amenorrhea of extremely lean women was attributed to loss of fat and hypothalamic dysfunction (Vigersky et al. NEJM 297:1141 (1977)). Based on these findings, a “critical weight” hypothesis was suggested (Frisch et al. Science 109:397 (1970)) extending the

assumption that a metabolic signal may be responsible for the initiation of reproduction. Moreover, adipose tissue has been viewed not only as an energy source but also as a direct regulator of female reproduction (R. E. Frisch Adipose Tissue and Reproduction Progress in Reproductive Biology and Medicine vol. 14 (1990)) since it converts androgens to estrogens via aromatization (P. K. Sifteri J. Endocrinology 89:119 (1981)).

The cloning, expression, and biological activities of leptin, the ob gene product, were described in a number of references, such as Pelleymounter et al. Science 269:540-543 (1995); Halaas et al. Science 269:543-546 (1995), and Campfield et al. Science 269:546-549 (1995).

While a variety of hormonal and other treatments have been proposed for lack of fertility in males or females, none have been entirely successful, and there remains a need for identifying improved and/or alternative therapies for enhancing fertility. In particular, improved methods and compositions should be effective, have minimum side effects, optionally be compatible with other hormonal treatments, and contribute to conception, pregnancy maintenance, and/or delivery of viable fetuses. The instant invention addresses this need and more.

SUMMARY OF THE INVENTION

One aspect of the invention is a method for restoring reproductive function in a reproductively impaired male or female host, the method comprising administering a leptin compound to the host for a time and in an amount sufficient to restore or enhance reproductive function.

A further aspect of the invention is a method of accelerating the onset of puberty in a male or female host, the method comprising administering a leptin compound to the host for a time and in an amount sufficient to cause the onset of puberty.

The leptin compound is administered to a female host from a time prior to impregnation through delivery of offspring, and preferably through lactation. The leptin compound may be a recombinant protein comprising the full secreted form of leptin. In other embodiments the leptin compound may be a recombinant protein comprising at least a biologically active fragment of leptin. The leptin compound is administered in a dosage from about 0.1 ng/kg body weight to 100 mg/kg body weight, typically subcutaneously, intradermally, intravenously, intramuscularly, intraperitoneally, orally, transdermally, via pulmonary delivery, via intranasal delivery, via controlled release, or via pump. The leptin compound is typically administered continuously or in discrete doses. The male or female host may suffer from a physiological defect of one or more hypothalamic, pituitary, or gonadal hormones. The host may be obese or non-obese. In some embodiments the host has a body mass index of less than about 20.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 depicts a 12% SDS-polyacrylamide gel showing 1 .mu.l aliquots of the recombinant human leptin before and after dialysis and 2 .mu.l and 3 .mu.l after dialysis. A 1 .mu.l aliquot from the metal chelate affinity column flow through shows bacterial proteins not bound to the column.

FIG. 2 depicts the body weights (a, b) and food intake (c, d) of ob/ob and db/db female mice during the 3 phases of leptin treatment for group 1 (a, c) and the single phase treatment for group 2 (b, d). In the first group, the 3 phases of the treatment are shown on top of each graph and outlined by vertical lines on each graph.

FIG. 3 depicts the body weight profiles of the two leptin treated ob/ob females after stabilization of their body weights and mating to a lean wild-type C57BL/6J male. The two mice showed copulatory plugs at days 46 and 54 of the treatment and gave birth at respectively, 64 and 73 days.

FIG. 4 depicts the PCR allele-typing of the R105X obesity mutation. The 8% polyacrylamide gel shows PCR products cleaved with Dde I from the homozygous C57BL/6J lean father, a leptin-treated homozygous ob/ob mother and their 5 newborn mice. The 472 bp PCR product generates upon cleavage with Dde I a constant 325 bp fragment and a 147 bp fragment diagnostic of the wild-type allele and 105 bp and 42 bp fragments diagnostic of the mutant ob allele. The newborn mice are all heterozygous at the ob locus as shown by the presence of both 147 bp and 105 bp fragments. The 42 bp fragment is off the gel. The DNA marker is .PHI.X cleaved with Hae III.

FIG. 5 depicts the time course of leptin clearance from the circulation of lean C57BL/6J females. Each point represents the mean .+-.SEM concentration of immunoreactive (IR) leptin in 3 adult females sacrificed at the indicated time. None of the 6 controls injected with PBS for the 0 time point had any detectable human leptin in their circulation, thus denoting the high specificity of the assay for human leptin on a mouse background. Note that leptin concentrations drop by almost 50% every hour, suggesting that the half-life of leptin is approximately 1 hour.

FIG. 6 depicts the effect of leptin treatment on body weight (A) and food intake (B) of prepuberal female mice. Either vehicle (solid circles) or leptin (open circles) treatment was initiated at 21 days of age when the animals were weaned. The addition of breeder males to both groups on day 27 resulted in a slight stabilization of body weight. Total food intake (B) was reduced by approximately 18% during the 6 days of treatment prior to the addition of the breeder males.

FIG. 7 depicts the acceleration of reproduction in leptin (white bar) versus vehicle-treated (black bar) mice. The number inside the bars represent the number of mice in each group. (A) Body weights of females at the time the copulatory plug was detected. PBS-treated mice had a mean body weight of 18.3. +-.0.3 g versus 15.9.+-.0.2 g for the leptin-treated group (P<0.001 by student’s t-test is denoted by the asterisk). (B) Percentage and age of mice with a copulatory plug in the PBS and leptin groups. Mice were compared at 3 age ranges of 30-39, 40-49 and 50-62 days of age. The asterisk denotes the statistical value of P=0.003 as determined by student’s t-test at 30-39 days of age. The age distribution of the leptin-treated mice is shifted to the left reflecting an earlier age of mating behavior. (C) Percentage of plugged mice from each group that delivered pups. 42% and 46% of plugged PBS and leptin-treated mice resulted in deliveries of newborn pups.

FIG. 8 depicts the effects of exogenous leptin on body weight (A), vaginal opening (B), onset of estrous cycle (C), uteri, oviducts and ovaries (D), LH (E) and 17-0-estradiol (F) in vehicle (O or black bar) and leptin (O or open bar) treated-group. A, B and C reflect continuous measurements from 21 to 29 days of age whereas D, E and F show determinations performed at the time of sacrifice. Asterisks denote statistical significance by student’s t-test. Uteri, P<0.004; ovaries, P<0.0001; oviducts P=0.001; LH, P=0.007. D2, P, E and D1 denote respectively dipstrus, proestrus, estrus and metestrus.

FIG. 9 depicts the effect of human recombinant leptin treatment on body weight and endogenous mouse leptin levels. (A) Body weights of prepuberal mice treated either with vehicle (0, n=12) or leptin (0, n=12). (B) 4 mice from each group were sacrificed at 30, 35 and 39 days of age to collect blood for endogenous leptin level measurements. Each time point represents the mean and SEM of 4 mice. The asterisk denotes statistical significance of leptin levels between 30 and 39 days of age (P=0.015 by student’s t-test).

FIG. 10 depicts the effect of leptin treatment or food restriction on the body weights of ob/ob males. Body weights are expressed as means and s. e. m. of 5 animals per group. Standard errors for most points were too small to be shown on the plotted scale.

FIG. 11 depicts the hematoxylin and eosin stained sections of testis from lean, untreated ob/ob, food restricted ob/ob and leptin treated ob/ob mice. (A) Overall appearance of seminiferous tubules (100 .times,magnification). The tubules are hollow and contain little sperm in the untreated and food-restricted ob/ob males. Lean and leptin-treated ob/ob males show normal tubules with abundant sperm. (B) (400.times.) Seminiferous tubules and Leydig cells. This view shows the sperm deficient lumen of the seminiferous tubules and shrunk interstitial Leydig cells in untreated and food-restricted ob/ob males. Leptin treated ob/ob males regained a testicular histology comparable to the 9 lean wild-type males. (C) (l000.times.) Magnification showing interstitial Leydig cells. The untreated and food-restricted ob/ob males show cytoplasm shrinkage of the Leydig cells, whereas the leptin-treated ob/ob males have normal Leydig cells identical to lean males.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Exemplary methods for cloning and purifying leptin compounds are described in scientific literature. See, for example, Pelleymounter et al. Science 269:540-543 (1995); Halaas et al. Science 269:543-546 (1995), Campfield et al. Science 269:546-549 (1995), and Chehab et al. Nat. Gen. 12:318-320 (1996). Leptin compounds suitable for use in the present invention, also termed “leptin” herein, may comprise a full-length leptin polypeptide obtained from a mammalian source, preferably human for the treatment of humans. Typically, the leptin compound will be a recombinant polypeptide. The recombinant polypeptide can be produced in mammalian, bacterial, or yeast expression systems. Suitable leptin compounds may also

comprise fragments, analogs, and derivatives, including truncated forms, of the full-length leptin polypeptide. Fusions of such compounds to a non-leptin polypeptide are included in the scope of the invention. In particular, a fusion protein incorporating the human leptin polypeptide used in the Examples section hereinafter, is at least one exemplary leptin compound which is suitable for use in the methods of the present invention.

Reproductively impaired female hosts suitable for treatment by the methods of the present invention will usually suffer from a deficiency in the hormonal system which supports ovulation, conception, maintenance of pregnancy, and/or delivery of offspring, typically being one or more hypothalamic, pituitary, or gonadal hormones. Administration of the leptin compound is believed to correct or help correct such deficiencies in the hypothalamic-pituitary-gonadal hormone system of the reproductively impaired female. “Reproductively impaired” is used interchangeably with infertile herein, and is intended to include amenorrheic females. Reproductively impaired females include those incapable of ovulation, conception, pregnancy maintenance, lactation, and/or delivery of full-term offspring, as well as those having difficulty in these areas. Administration of the leptin compound will restore and/or enhance the ability of such females to conceive and bear children. Similarly, infertile males include those incapable of impregnating females. “Sterile” is used interchangeably with “infertile” and “reproductively impaired” herein.

The male or female hosts treated by the method of the present invention may be obese or non-obese. It is believed that administration of the leptin compounds will restore hormonal function associated with obesity or gross alteration in body weight as well as other conditions which are not associated with obesity.

Thus, the present invention provides methods for restoring reproductive function in a reproductively impaired male or female host, the method comprising administering a leptin compound to the host for a time and in an amount sufficient to restore or enhance reproductive function. In some embodiments of this invention a leptin compound will be administered to a male or female host to accelerate the onset of puberty. “Puberty” as used herein includes the initiation and completion of the first menstrual cycle. Typically, the male or female host will have experienced a delayed onset of puberty or be at risk for a delayed onset of puberty, typically as a result of gross deviation in body weight, before treatment with a leptin compound. The leptin compound will usually be administered in a dosage from 0.1 ng/kg body weight to 100 mg/kg body weight. Amounts effective for this use will depend on, e.g., the leptin composition, the manner of administration, the weight and general state of health of the patient, and the judgment of the prescribing physician.

The leptin compound will typically be administered to a female host during at least a portion of the time from prior to impregnation through delivery of the offspring, usually during the entire period from prior to impregnation through delivery of the offspring, and preferably through lactation.

The leptin compound will typically be administered to a male host during at least a portion of the time from prior to impregnation of a female to when impregnation has been confirmed.

The leptin compound will typically be administered to a host experiencing a delayed onset of puberty for at least a period prior to the onset of puberty through puberty, and possibly through a period of desired impregnation and delivery of offspring, typically in an amount sufficient to cause the onset of puberty.

The treated male or female host is typically human, but the method is effective with other mammalian hosts, such as mice. The host will usually suffer from an insufficiency of one or more hypothalamic, pituitary, or gonadal hormones of the type necessary for or otherwise involved in reproductive fertility. In some cases the hosts will be obese; in other cases the hosts may be non-obese. Obesity is defined as including having a body mass index (BMI; weight in kg/(height in meters).sup.2) over about 30. In some instances, the non-obese host will have a BMI of less than about 20.

The leptin compound may be administered subcutaneously, intradermally, intravenously, intramuscularly, intraperitoneally, via pulmonary delivery, via intranasal delivery, transdermally, orally, via controlled release, via pump, or by any other conventional route of administration for polypeptide drugs. Typically, the leptin compound will be administered continuously during the period of administration, i.e., being delivered at least once per day or via controlled release techniques, such as via transdermal patches.

In some embodiments, the invention provides compositions for administration which comprise a solution of leptin dissolved or suspended in an acceptable carrier, preferably an aqueous carrier. A variety of aqueous carriers may be used, e.g., water, buffered water, 0.8% saline, 0.3% glycine, hyaluronic acid and the like. These compositions may be sterilized by conventional, well known sterilization techniques, or may be sterile filtered. The resulting aqueous solutions may be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile solution prior to administration. The compositions may contain pharmaceutically acceptable auxiliary substances as required to approximate physiological conditions, such as pH adjusting and buffering agents, tonicity adjusting agents, wetting agents and the like, for example, sodium acetate, sodium lactate, sodium chloride, potassium chloride, calcium chloride, sorbitan monolaurate, triethanolamine oleate, etc.

The concentration of leptin in the pharmaceutical formulations can vary widely, i.e., from less than about 0.1%, usually at or at least about 2% to as much as 20% to 50% or more by weight, and will be selected primarily by fluid volumes, viscosities, etc., in accordance with the particular mode of administration selected.

For solid compositions, conventional nontoxic solid carriers may be used which include, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharin, talcum, cellulose, glucose, sucrose, magnesium carbonate, and the like. For oral administration, a pharmaceutically acceptable nontoxic composition is formed by incorporating

any of the normally employed excipients, such as those carriers previously listed, and generally 10%-95% of active ingredient, that is, one or more leptin compounds of the invention, and more preferably at a concentration of 25%-75%.

For aerosol administration, leptin is preferably supplied in finely divided form along with a surfactant and propellant. Typical percentages of leptin are 0.01%-20% by weight, preferably 1 %-10%. The surfactant must, of course, be nontoxic, and preferably soluble in the propellant. Representative of such agents are the esters or partial esters of fatty acids containing from 6 to 22 carbon atoms, such as caproic, octanoic, lauric, palmitic, stearic, linoleic, linolenic, olesteric and oleic acids with an aliphatic polyhydric alcohol or its cyclic anhydride. Mixed esters, such as mixed or natural glycerides may be employed. The surfactant may constitute 0.1%-20% by weight of the composition, preferably 0.25-5%. The balance of the composition is ordinarily propellant. A carrier can also be included, as desired, as with, e.g., lecithin for intranasal delivery.

The leptin compositions of the invention can additionally be delivered in a controlled release system such as a depot-type system, an encapsulated form, or an implant by techniques well-known in the art. The compositions of the invention can also be delivered via a pump, such as a minipump, to the male or female host.

The following examples are offered by way of illustration, not by way of limitation.

A. Results and Discussion

This study investigated the ability of leptin to correct the reproductive defect of the sterile female ob/ob mouse.

The human ob cDNA sequences spanning amino acids 22 to 167 (Zhang et al. Nature 372:425-32 (1994)) and representing the secreted ob protein were cloned into the expression vector pQE30. The 16 Kd ob protein was overexpressed in E.coli, purified and renatured by dialysis (FIG. 1).

The refolded leptin protein was injected intraperitoneally into 2 groups of experimental ob/ob female mice at a dose of 10 .mu.g/g of initial body weight. Control ob/ob mice were injected with identical volumes of phosphate buffered saline (PBS). The first group consisted of 4 ob/ob animals (2 controls and 2 experimentals) and the second group of 10 ob/ob animals (5 controls and 5 experimentals).

In the first group, the two experimental ob/ob female mice (ob-5 and ob-6), weighed respectively, 48.5 g and 51.7 g whereas the two control mice weighed 53.8 g and 50.0 g. In addition, 2 female db/db mice also received leptin injections to test for non-specific weight loss

as these mice are resistant to leptin effects, presumably due to a defect in the leptin receptor (Coleman et al. Am. J. Phys. 217:1298-1304 (1969); Coleman, D. J. Diabetoloqia 9:294-298 (1973)). Food intake and body weights were continuously measured to determine the efficacy of the treatment.

The leptin treatment for the first group consisted of 3 phases. In the first phase which lasted 8 days, the mice received two injections per day of PBS or leptin. At the end of the first phase, weight loss in the treated animals was 24% and 27% of their original body weight (FIG. 2A). In contrast, the body weights of both ob/ob PBS-controls and one leptin treated db/db mouse increased by 6% whereas the second db/db treated mouse lost 1% of body weight (FIG. 2A). Food intake of leptin treated ob/ob mice was markedly reduced to 13% of the food intake of control ob/ob mice (FIG. 2B). Withdrawal of the leptin injections in the second phase showed in the ob/ob mice, a rapid increase in food consumption and body weight, demonstrating the need for repeated leptin injections to maintain a biological effect (FIG. 2A and 2B). The third phase consisted of single daily leptin injections which produced a biological response similar to the first phase, albeit at a lower rate as evidenced by the slopes of the two body weight curves during phases 1 and 3 (FIG. 2A). Injections were continued for a total of 42 days in the two leptin treated ob/ob mice until their body weights stabilized to approximately 28 g and 25 g corresponding to 46% and 48% reductions in body weight. The body weights of the db/db mice changed minimally (FIG. 2A) whereas their food intake increased in parallel with that of PBS injected ob/ob controls (FIG. 2B).

In the second group, the experimental ob/ob mice were injected intraperitoneally once daily with a 10 .mu.g/g initial body weight of leptin for 30 days. The mean body weights of the 5 ob/ob controls after 30 days was 55.9.+-.2.0 as compared to 27.8.+-.0.9 for the 5 leptin treated ob/ob mice. The treated mice had lost 40% of their original body weight whereas the control mice increased their body weight by 13% (FIG. 2C and 2D).

After 6 weeks of leptin treatment, at a time where body weight had stabilized, the 2 PBS-controls and 2 leptin-treated mice (ob-5 and ob-6) from the first group were mated with a normal C57BL/6J male mouse. A copulatory plug was detected only in ob-5 and ob-6 shortly thereafter, but not in the controls. The formation of copulatory plugs demonstrates the occurrence of estrus and ovulation in the treated ob/ob females. Leptin injections were then continued at half the original dose. The treated females started to show a significant increase in body weight at day 12 p.c, and delivered newborn pups at 20.5 and 19.5 days p.c. (FIG. 3). Parturition occurred in both treated mice over at least 36 hours resulting in the delivery of 6 (ob-5) and 2 (ob-6) pups.

Although the mice were alive and fully developed at birth, none of the newborns survived. Five intact or partially eaten newborn mice were recovered from ob-5 and 2 mice from ob-6. DNA was extracted from the newborns to determine their genotypes at the ob locus. PCR primers bracketing codon 105 which is the site of the mutation in the ob/ob mouse, were designed and used for DNA amplification. The 472 bp amplified PCR product contains in the homozygous normal mouse a single Dde I site which produces 325 bp and 147 bp fragments upon cleavage with Dde I. However, the R105X obesity mutation generates an additional Dde I site which

results in fragments of 325 bp, 105 bp and 42 bp in the homozygous ob/ob mouse. PCR testing showed that the lean male mouse who fertilized both treated females was homozygous for the wild-type allele, whereas both mothers were homozygous for the mutation and all newborn mice were heterozygous for R105X (FIG. 4).

In the second group, 4 ob/ob controls and 4 ob/ob leptin-treated mice whose body weight stabilized as a result of the leptin treatment were also mated to C57 BL/6J wild-type lean males. All 4 leptin-treated, but not any of the control ob/ob mice, became pregnant. Furthermore, ob-5, who was under continuous leptin treatment even after delivery, became pregnant a second time, demonstrating that the entire process can be repeated.

Although the levels of reproductive hormones in the pregnant females were not measured, the entire process of ovulation, pregnancy and parturition could not have occurred in the absence of these hormones. The previous findings that the ob/ob females can respond to the effects of these hormones either exogenously or in vivo after ovarian transplants demonstrates that leptin can stimulate the production of hormones required for ovulation, pregnancy and parturition. Furthermore, these studies show that the sterility defect in adult ob/ob female mice is a reversible process that can be corrected with leptin treatment. Therefore, leptin is not only a satiety factor that can suppress appetite and promote lipolysis (Pelleymounter et al. Science 269:540-543 (1995); Halaas et al. Science 269:543-546 (1995); Campfield et al. Science 269:546-549 (1995); Weigle et al. J. Clin. Inv. 96: 2065-2070 (1995)) but also plays an important role in reproductive physiology.

It is not clear why the newborn mice were eaten by the mothers. It is possible that daily handling and injection of the mothers throughout gestation and especially before and after delivery is a contributing factor to this effect. It is also possible that the mothers failed to nurse the newborns, from possibly a lack of prolactin secretion.

Rescue of the sterility phenotype in ob/ob females has important implications for the husbandry of this strain. Whereas ovarian transplants have been a successful approach to the maintenance and propagation of the ob/ob strain, an alternative solution, leptin treatment, is available as a result of the studies described herein.

 

B. Methods

1. Expression and purification of the recombinant human ob protein.

Human ob cDNA sequences representing the mature secreted human protein (from amino acids 22 to 167) were amplified by RT-PCR from normal human fat mRNA using human specific cDNA primers based on the Genbank sequence U18915. The cDNA was subcloned by blunt-end ligation into pSK+ srf (Stratagene), recovered as a Bam HI restriction fragment and inserted into the expression vector pQE30 (Quiagen). The recombinant ob protein was thus under the control of a T5 bacteriophage promoter, had a hexahistidine tag at the amino terminus and a stop codon immediately following amino acid 167. The DNA construct was transformed and overexpressed

in E. coli following induction by IPTG. A crude protein lysate was prepared under denaturing conditions and the ob protein purified by metal chelate affinity chromatography on a nitrilo-tri-acetic acid (NTA) resin. The bound protein was finally eluted and recovered in 20 ml o 4.6M urea, 0.077 M Na2HPO4, 0.077M Tris pH 8.0 and 250 mM imidazole. The eluted protein was allowed to refold by slow dialysis of the denaturant successively in 4 M, 3 M, 2 M, 1 M, 0.5 M urea in phosphate buffered saline (PBS). Final dialysis was in 3 changes of PBS. Each dialysis step was performed for at 12-24 hours in 6000-8000 molecular weight cutoff (MWCO) tubing at 4,degree. C. against 50 volumes of solution. Aliquots of the refolded protein were used to determine its concentration by the Bradford protein assay (Biorad Laboratories). In addition, purity and recovery of the protein after dialysis were estimated by fractionation on a 12% stacking SDS-polyacrylamide gel. Electrophoresis was performed at 100V, 25 mA for 2 hours in 25 mM Tris, 250 mM glycine and 0.1% SDS. The gel was then stained with Coomassie Blue and extensively destained in 45% methanol, 10% acetic acid.

2. Leptin treatment of the ob/ob mice.

Homozygous female C57BL/6J-ob/ob and C57BL-KsJ-db/db mice were purchased from the Jackson Laboratories and housed at the UCSF Animal Care Facility under alternating 12-hours light and dark periods.

For the first group of mice, the initial phase of the treatment (days 1 -8) consisted twice daily (between 8- 9 a.m. and 5-6 p.m.) of either PBS or recombinant human leptin injections at a dose of 10 .mu.g/g of initial body weight. In the second phase (days 9-13), injections were completely withdrawn and in the third phase, which began at day 14, the mice received a single injection (between 5-6 p.m.) per day of either PBS or leptin. The second group received once daily a 10 .mu.g/g of initial body weight dose throughout the single phase treatment. The dose of leptin was reduced to half upon observation of the copulatory plug and continued at a single injection daily throughout gestation until delivery. The mice were weighed periodically and food consumption deduced by weighing the food left in the cage at periodic intervals. The dead newborn mice were frozen at -20.degree. C. until DNA extraction.

3. Genotyping of the newborn mice.

5 mm sections from the frozen embryos or tail of the ob/ob mother and lean father were obtained by excision. The tissue was first homogenized in 10 mM Tris-1 mM EDTA (TE) to generate a cell suspension. SDS was then added to 0.5% to lyse the cells and the mixture extracted with phenol- chloroform followed by ethanol precipitation. The DNAs were dissolved each in 50 .mu.l of TE and 5 .mu.l aliquots subjected to DNA amplification by the polymerase chain reaction (PCR). The PCR primers consisted of 5’ CTGGTTCTTCACGGATATCATTG 3’ and 5’ AGGGAGCAGCTCTTGGAGAA 3’. The amplification reaction was carried out in 50 .mu.l for 35 cycles at 95.degree, C.55.degree. C., and 72.degree. C. for 30 sec. after which a discrete 472 bp product was obtained. A 7 .mu.l aliquot was then digested with Dde I (New England Biolabs) and the digested products fractionated on a native 8% polyacrylamide gel. The gel was stained with ethidium bromide and the products visualized under ultraviolet light.

II. Triggering of reproductive function in prepuberal normal female mice

This study demonstrated that leptin is a critical signal for the initiation of reproduction. Without being limited to any one theory, leptin may stimulate GnRH release so as to initiate puberty.

 

A. Measurement of Leptin Half-life

An advantage of using human leptin for these experiments lies in the ability to measure independently mouse endogenous and human exogenous leptin with specific radioimmunoassays that have virtually no cross reactivity with each other (<0.2%). Measurement of leptin levels with the human specific radioimmunoassay revealed undetectable levels in control mice, thus demonstrating the specificity of the assay.

The clearance time of exogenous human recombinant leptin was determined to calculate the frequency of injections in subsequent experiments as follows. Twenty eight C57 BL/6J adult females weighing 24.1+-.0.7 g, fed ad lib., were divided between a control and a leptin group. Six mice were injected with PBS vehicle solution and 21 others with a 4 .mu.g/g body weight dose of immunoreactive leptin. Control mice were sacrificed immediately after saline injection whereas 3 leptin-injected mice were sacrificed at each 1, 2, 3, 4, 5, and 7 hours. Blood was collected by cardiac puncture and the plasma separated by centrifugation and frozen at -20.degree. C. until use.

In the injected animals, immunoreactive leptin (IR-L) peaked at 1 hour and started to decline approximately by 50% each hour until it was undetectable at 7 hours post injection (See FIG. 5). Therefore, leptin has a half-life of approximately 1 hour. Consequently, leptin was administered daily in subsequent experiments between 5-7 p.m. just prior or soon after the onset of the dark period.

Because previous studies have shown that large amount of exogenous leptin are required to exert a biological effect in normal C57BL/6J mice (Pelleymounter et al. Science 269:540 (1995); Halaas et al. Science 269:543 (1995)), exogenous leptin was administered in these experiments at 2 .mu.g/g body weight (half the dose used in the clearance study).

 

B. Fertility of leptin-treated lean female mice

To determine whether leptin-treated mice will reproduce earlier than control animals, fertility was selected as an endpoint of the experiment. The rationale of this study was derived from the hypothesis that if fat is a determinant for puberty, then leptin, which is secreted from fat may be a critical factor in initiating reproductive function. Therefore, treatment of prepuberal mice with exogenous leptin would “trick” neuroendocrine pathways involved in reproduction into acting as if the animal accumulated a certain amount of fat as reflected by the elevated levels of leptin in its circulation.

Prepuberal C57BL/6J mice (n=25) were weaned at 21 days of age and divided into two groups. One group (n=13) weighing 10.2.+-.0.4 g received one daily injection of the human recombinant leptin whereas the other group (n=12) weighing 10.3 .+-.0.3 g received identical volumes of the phosphate buffered-saline (PBS) vehicle solution. Breeder males were then placed at day 28 in each cage at a ratio of one male per 3 females until a copulatory plug was detected in each female whose weight and age was recorded. Plugged females were kept under either treatment until 20 days after detection of the plug and were housed each in a separate cage to assess whether the copulatory plug was associated with a successful pregnancy.

All procedures were approved by the UCSF Committee on Animal Research. Two-week-old lactating prepuberal C57 BL/6J female pups were obtained from the Jackson Laboratories and allowed to recover for one week prior to initiation of the experiment. All male pups were removed from the litters at 2 weeks of age. Mice were housed at the UCSF Animal Care Facility and maintained at 20.degree. C. with a 12 hrs. light, 12 hrs. dark cycle (lights on at 6 a.m., off at 6 p.m.). Mice were treated with human recombinant leptin as described above. The leptin preparation was quantitated by radioimmunoassay (Linco Research, St. Louis Mo.) and injected intraperitoneally at a dose of 2 .mu.g/g body weight while control animals received phosphate buffered saline (PBS) injections. Prepuberal C57BL/6J mice (n=25) born on the same day were weaned at 21 days of age and housed in 7 cages consisting each of 3 mice and 1 cage of 4 mice. Animals from the same litter were placed into different cages such that no cage contained two mice from the same litter and divided into two groups. One group (n=13) weighing 10.2.+-.0.4 g received one daily injection of 2 .mu.g/g body weight IR-L whereas the other group (n=12) weighing 10.3.+-.0.3 g received identical volumes of the phosphate-buffered-saline (PBS) vehicle solution. The mice were continuously monitored for body weight, food intake and vaginal opening which occurred in both groups at 26-27 days of age. Young female mice were housed away from males and had no contact with males or their urine until day 28, when a sexually competent adult C57 BL/6J male was added to each of the 8 cages at a ratio of one male per 3 females to initiate mating. Plugged females were kept under either treatment until 20 days after detection of the plug and were housed each in a separate cage to assess whether the copulatory plug was associated with a successful pregnancy. All statistical P values in this study were calculated by two-sample t-test using a Macintosh computer equipped with statistical package.

Leptin treatment of the young mice resulted in a slowdown of growth as compared to the control group (FIG. 6A) and was statistically significant from the third day (P=0.003) and throughout the treatment. This effect was primarily due to a decrease in food intake, as shown in FIG. 6B.

If leptin is involved in signaling puberty and the onset of reproduction, then leptin-treated mice, despite having a lower body weight (but high leptin levels) as a result of the thinning effects of leptin, will attain reproductive maturity earlier than the vehicle treated group. Indeed, these results showed that at the time the copulatory plug was first detected, leptin-treated mice had reached a body weight of 15.9.+-.0.2 g as opposed to 18.3.+-.0.3 g for the vehicle group (FIG. 7A), accounting for a 13% difference in body weight (P<0.0001). Furthermore, leptin-treated mice were plugged at an earlier age than the vehicle treated group. Thus, between the ages of

30-39 days, plugs were detected in 85% of leptin-treated mice (11 of 13 mice, P=0.003) and 17% (2 of 12 mice) of vehicle treated mice. The remaining 2 leptin-treated mice (15%) were plugged at 44 and 46 days of age as opposed to 40-49 and 50-62 days of age for respectively 6 (50%) and 4 (33%) of vehicle-treated mice (FIG. 7B).

Therefore, leptin treatment resulted in a significant acceleration of behavioral estrus and mating capability when the copulatory plug was used as a reproductive index. Thus, the attainment of the appropriate age and weight that allows initiation of reproduction in the control group, is advanced in the leptin-treated group owing to the elevated levels of leptin that have signaled neuroendocrine pathways that the animal has accumulated enough fat since leptin was shown to be a brain marker for adiposity (Frederich et al. Nat. Med. 12:1311 (1995); Maffei et al. Nat. Med. 11:1155 (1995)).

The proportion of plugged mice from both groups that carried out successful pregnancies at their first estrus was determined by delivery of newborn pups. Thus successful pregnancies and deliveries were comparable in both groups and consisted of 42% and 46% in vehicle and leptin groups, respectively (FIG. 7C). Altogether, leptin treatment resulted not only in an acceleration of behavioral estrus and mating but was also accompanied with normal pregnancies and deliveries, demonstrating successful ovulation among the leptin-treated mice.

To assess whether leptin treatment affected maturation of the reproductive tract in prepuberal mice, we determined in vehicle and leptin groups the timing of vaginal opening, initiation and progress of the first estrous cycle, the weights of uteri, ovaries and oviducts (which are excellent indices and bioassays of hormones action as well as LH and estradiol levels). Mice were weaned at 21 days of age and separated into PBS (n=12) and leptin (n=12) groups. Twenty four C57 BL/6J females were weaned at 21 days as above from different litters and divided equally with respect to litter of origin into vehicle (n=12) and leptin groups (n=12). Three animals were housed per cage with no litter mates placed in the same cage. The mice were treated with either PBS or leptin as above for 8 days and sacrificed on day 29 to collect blood, ovaries, oviducts and uteri. Dissection of each organ was carried out under a binocular microscope to ensure removal of contaminating tissues. Organs were weighed on a Metier AE160 high precision analytical balance.

Leptin treated mice grew at a slower rate than vehicle treated animals, demonstrating again the effect of leptin on body weight (FIG. 8A). At the reproductive level, vaginal opening occurred in respectively 2, 1, 3, and 6 leptin-treated mice at respectively 22, 23, 24 and 25 days of age. However vaginal opening occurred in 3, 6, 2 and 1 vehicle treated mice at respectively 25, 26, 27 and 28 days of age (FIG. 8B). Thus vaginal opening is advanced up to 4 days as a result of leptin treatment.

As a consequence of early vaginal opening, normal cyclicity was initiated in leptin treated mice prior to the control group (FIG. 8C) such that by day 29, 5 out of 12 leptin-treated mice had passed through estrus and progressed to metestrus (D1) stage thereby completing their first estrous cycle whereas none of the mice in the control group had reached that point. Mice, not exposed to males, have normally their first fully cornified smear 5-8 days after vaginal opening (Stiff et al. Endocrinology 84:492 (1974)).

A corollary of this experiment and the fertility experiment described above demonstrated that the biological actions of estrogens that are first evidenced by vaginal opening are not sufficient to elicit reproduction in control mice. However, in the experimental group, the presence of elevated levels of leptin with endogenous estrogens induce a rapid onset of reproduction. Thus, vaginal opening in mice lacking leptin is a sensitive index of estrogens action but not of fertility, whereas in leptin-treated mice, vaginal opening is associated with fertility.

Evidence of gonadal steroids action was determined by assessing the weights of reproductive organs which are targets for hormones that are released transiently, but that produce long term effects on target tissues. Thus, the action of estradiol can be best evidenced by its striking and stimulatory effects on the hypertrophy and hyperplasia of uterine tissues thereby promoting uterine growth. In leptin-treated prepuberal mice, uterine weights consisted of 20.8.+-.2.1 mg as opposed to 13.6.+-.0.8 mg in controls (P=0.004) representing a 53% increase. Similar effects were found on ovarian (4.8.+-.0.2 mg for vehicle vs. 6.6.+-.0.3 mg for leptin. P<0.0001) and oviducts weights (3.2.+-.0.2 for control vs. 4.6 .+-.0.3 for leptin, P=0.001) which increased respectively by 37.5% and 43.8% as a result of leptin treatment (FIG. 8D). Therefore, leptin treatment of the mouse at an early age resulted in a premature release of the hormones necessary for maturation of the reproductive tract.

Hormone levels for the gonadotropin LH and the gonadal steroid 17-.beta.-estradiol were determined at day 29, when the mice were sacrificed. LH was assayed on 50 .mu.l plasma using a rat specific immunoassay purchased from Peninsula Laboratories (Belmont, Calif.). 17-.beta.-estradiol levels were determined on 200 .mu.l plasma by an ultrasensitive radioimmunoassay purchased from Diagnostic System Laboratories (Webster, Tex.). Unknown samples from both assays fell into the linear portion of each standard curve. LH levels consisted in control and leptin-treated mice of respectively, 6.9.+-.0.4 ng/ml and 5.2.+-.0.4 ng/ml, a statistically significant decrease (P=0.007) of 24.6% (FIG. 8E). However, I7-.beta.-estradiol levels were comparable in both groups and consisted respectively of 10.3.+-.1.1 pg/ml and 9.5.+-.1.1 pg/ml for control and leptin-treated groups (FIG. 8F). Altogether, the results displayed in FIG. 8 show that leptin treatment of prepuberal mice causes at the reproductive level a concomitant stimulation of vaginal opening and ensuing first estrous cycle. These effects were mediated by the target actions of gonadal steroids which caused the reproductive tissues to mature earlier in leptin-treated mice. Because at the time of sacrifice, most control animals had not already ovulated, the findings that LH levels are elevated in control animals are consistent with the rising levels of LH prior to ovulation.

Conversely, the depressed levels of LH in leptin-treated animals reflect the completion or near completion of their first estrous cycle. Taken in this context, 17-.beta.-estradiol levels thus reflect antiparallel effects whereby estrogen levels are on the rise in control animals that are progressing towards completion of their first cycle but decreasing in most leptin-treated mice that have already proceeded either close or beyond their first cycle.

In order to determine the levels of endogenous leptin at the time of reproductive maturation, C57 BL/6J females were weaned at 24 days of age and treated with either PBS (n=l 2) or human recombinant leptin (n=12). Four animals from each group were sacrificed at 30, 35 and 39 days of age and blood collected for leptin measurements. The rationale of this experimental was two-fold: to assess endogenous leptin levels in vehicle treated mice at the time of reproductive maturation and to find out whether production of endogenous leptin is affected by the administration of exogenous leptin. As in the previous experiment, leptin treatment resulted consistently in a slowdown of body weight growth as shown in FIG. 9A. Plasma leptin levels in the vehicle group at 30, 35 and 39 days of age (FIG. 9B) consisted of 2.3+-.0.1 ng/ml, 2.9.+-.0.4 ng/ml and 3.7.+-.0.4 ng/ml. A 61% statistically significant increase (P=0.015) in leptin was thus found between 30 and 39 days of age. Interestingly, in the treated group, leptin levels did not rise but stabilized at 2.9-3.3 ng/ml showing that exogenous leptin treatment suppressed endogenous leptin production thereby suggesting the presence of a leptin producing feedback loop which usually increases endogenous leptin as the mouse progresses to puberty.

Overall, these findings demonstrated that leptin acts as a signal for puberty essentially as evidenced by its effects on the acceleration of reproduction in prepuberal mice, on vaginal opening, on the onset of the first estrous cycle and on maturation of reproductive tissues which are accompanied by changes in LH and 17-.beta.-estradiol levels. The sites of actions of leptin could either be on the brain, on the ovaries or both since leptin receptors have also been identified on mouse ovaries (Chehab et al. Nat. Gen. 12:318- 320 (1996)). However, the brain appears to be the prime target since transplantation of either the ob/ob or the db/db defective ovary into a normal mouse restores its function independent of whether the original host has a leptin (ob/ob) or leptin-receptor (db/db) defect.

 

III. Rescue of Male Sterility

 

A. Leptin treatment and food restriction of ob/ob males

Experiments were approved by the UCSF Committee on Animal Research. The animals were purchased from the Jackson Laboratories (Bar Harbor, Mee) and maintained each in individual cages at the UCSF Animal Care facility under a 12 hr. dark light regimen (lights on at 6 a.m., off at 6 p.m.). Human recombinant leptin was prepared as described above. Ten morbidly obese adult homozygous ob/ob males housed in individual cages were equally divided into a food-restricted group (ob/ob 1-5) and a leptin-treated group (ob/ob 6-10). In order to accelerate weight loss, the recombinant protein was injected daily intraperitoneally at a single dose of 20 .mu.g/g initial body weight. The treatment was for 60 days to allow enough time for the food restricted ob/ob males to stabilize their body weight loss. Leptin-treated ob/ob males had continuous access to food whereas food-restricted ob/ob males were pair-fed to the leptin-treated group and allowed to consume daily 1 g of food (Purina-Mills, FormuLab Diet 5008) for 46 days and 3 g for the remaining 14 days. Water was provided without any restriction to both groups.

B. Matings of ob/ob mice

After 12 days of leptin treatment, 2 normal females were placed with each ob/ob male from both groups. Females with food-restricted ob/ob males were placed in the cage between 5 p.m. and 6 a.m. for mating after the ob/ob male had consumed the 1 g of food. These females were removed the next morning and placed collectively in cages where they access to food which they lacked of during the dark period. This cycle was repeated throughout the treatment.

 

C. Organ weights and histology

In order to determine some of the parameters that contributed to their fertility, control and leptin-treated ob/ob mice were sacrificed by an overdose of 2.5% Avertin at day 61 along with 5 lean male C57/BL mice and 3 untreated ob/ob males which were fed ad lib. To gain further insights into the effects of leptin treatment on the anatomy of the testis, histological examination of testicular sections from lean, untreated ob/ob, food restricted ob/ob and leptin treated ob/ob mice were carried out. The seminal vesicles and testis of all animals were weighed and histology of the testis examined. The seminal vesicles and testis were dissected and weighed immediately. The testis were then fixed in fresh 4% paraformaldehyde in PBS for 48 hours and processed for paraffin embedding, sectioning and hematoxylin and eosin staining. Statistics were determined by two-sample Student’s t-test,

 

D. Food consumption and body weight of leptin-treated ob/ob males

Mean daily food intake of each leptin treated ob/ob male during the first 12 days of treatment consisted of 0,8+0.1 g (Table 1). The food-restricted and leptin-treated groups entered the treatment, respectively, with 68.7+1.2 g and 65.6+2.2 g and lost respectively after 12 days of treatment 24.2+0.5% and 32.1+1.2% of their initial body weight (FIG. 10). Long term leptin treatment resulted in an increase of food consumption to approximately 2.9+0.3 g at day 45 (Table 1) which was used as a reference to increase the allotment of food to the food-restricted males for the last two weeks of treatment. The increase in food consumption of the leptin-treated ob/ob males could be as a result of partial resistance to the administered exogenous leptin. The body weights of 5 ob/ob mice treated for 12 days with a PBS vehicle solution did not significantly change (data not shown) and were thus excluded from subsequent matings since no weight loss was observed.

 

E. Fertility of ob/ob males

Each ob/ob mouse was housed at day 12 with 2 lean females to determine if weight loss, whether induced by food-restriction or leptin treatment, was accompanied with fertility. Demonstration of fertility in the leptin-treated ob/ob males was determined by the delivery of newborn pups 19-20 days after detection of the copulatory plug in lean females.

Food restriction of the ob/ob males resulted in a significant weight loss of 40.6.+-.0.5% at 30 days and 48.1.+-.1.8% at 60 days. However, none of the lean females that were mated with the

food-restricted males had a copulatory plug nor any pregnancy resulted from diet-induced weight loss in the ob/ob males. Monitoring of body weight and food intake of the lean females revealed that they maintained a constant weight and consumed their food during the day since food was not available when they were placed with the food-restricted ob/ob males (data not shown). Therefore, induction of weight loss by food restriction in the ob/ob males did not result in correction of their sterility suggesting that excess adipose tissue is not the cause of sterility.

In contrast, mating of the 5 leptin-treated males with the 10 lean females resulted in copulatory plugs, pregnancies and deliveries in all the breeder females (Table II) demonstrating unequivocally successful functional reconstitution of the mate ob/ob reproductive system in the presence of leptin. Thus, correction of the sterility in ob/ob mice occurred despite an initial body weight of 65.6+2.2 g, thus indicating that accumulation of excessive fat does not permanently block the immaturity of the hypothalamic-pituitarygonadal axis which becomes functional as a result of leptin treatment.

F. Organ weights and testicular histology

Seminal vesicles weights were not statistically significant among the 4 groups. However, testis weight which is mostly indicative of overall spermatogenic activity and testosterone content was significantly different between lean and untreated ob/ob mice (P<0.001) and food-restricted versus leptin-treated ob/ob mice (P<0.001) as shown in Table III, Interestingly, comparison of the untreated ob/ob and food restricted ob/ob mice resulted in a 60% increase in testicular weight of the latter group (P<0.009) without, however, correction of their sterility. Thus, one effect of the leptin-induced fertility treatment is a normalization of testicular weight and function. Previous studies have shown that the overall structure of the ob/ob testis is abnormal and characterized most aberrantly by multinucleated spermatids, few spermatozoa and a small amount of interstitial Leydig tissue (STET) reduced by more than 50% (Heilman, B. Ann. N.Y. Acad, Sci. 131:541-558 (1965)). Consistent with these observations, two prominent histological features shown in FIG. 11 are noticeable. First, the lumen of the seminiferous tubules in the untreated and food restricted ob/ob males appear hollow and contain strikingly less sperm than the lean male mouse. Second, the interstitial Leydig cells of the obese mice are atrophied due visibly to a shrinkage in their cytoplasm. Food restriction of ob/ob males does not alter their abnormal histology and infertility as previously shown (Heilman et al. Acta Endocrinol. 44:20-26 (1963); Barash et al. Endocrinology 137:3144-3147 (1996)) and by the present experiments (FIG. 11).

In contrast, the seminiferous tubules of the leptin-treated ob/ob males become more abundant with mature sperms and the Leydig cells regain their usual morphology and clustering characteristic. Therefore, leptin treatment of the ob/ob males stimulates spermatogenesis and allows regeneration of the Leydig cells which should then be capable of producing adequate amounts of testosterone.

Therefore, the present study demonstrated that leptin treatment corrects the sterility of ob/ob males as effectively as in ob/ob females.

LEPTIN TECHNOLOGY TRANSFER, TECHNICAL SUPPORT AND DOCUMENTATION

Introduction

The purpose of this document is to define the scope of the transfer of the Manufacturing Processes from Amgen to Amylin and/or Amylin’s designated CMO(s) approved by Amgen, as set forth herein, as well as define respective roles and responsibilities of the Parties. The Manufacturing Process for A-100 Leptin was developed by Amgen in the late 1990’s and was last run at commercial scale in the LakeCentre, CO facility. A joint technology transfer team will be formed including experts from Amgen as well as Amylin and the designated CMO(s) to facilitate and coordinate the transfer of Manufacturing Processes.

Analytical Methods for Drug Substance and Drug Product

 

    Amgen is transferring the methods “as is” and will not do any additional development work on the methods prior to the transfer (with the exception of the bioassay, Host Cell Protein assay, and DNA assay, which will require some additional development work prior to the transfer).

 

    Amgen will not qualify/characterize, or validate the analytical methods.

 

    Upon reasonable request and sufficient advance notice, and subject to Amgen resource availability, Amgen will provide lab training for the non-compendial methods for the A-100 process if deemed necessary by Amylin/CMO. Such training would be provided at Amgen Thousand Oaks (“ATO”) and each Party will bear its own costs and expenses incurred in connection with such training.

 

    Amgen will provide master cell bank (MCB) and working cell bank (WCB). Amgen will perform any necessary retest/stability testing on the cell banks if they are to expire within the first six months of this Agreement. Amgen will also provide any reasonable cell banks and critical reagents necessary to perform any of the non-compendial analytical methods such as the bioassay and host cell protein assays. Amgen will also provide vials of bioassay master cell bank.

 

    The CMO will re-qualify the MCB and WCB.

 

    The following methods are considered to be compendial:

 

    Protein concentration (AO 120)

 

    Spectrophotometry (protein/DNA) (A0101)

 

    pH (A0105)

 

    Endotoxin (A0S20)

    Appearance (A0221)

 

    Moisture/Karl Fischer (A0406)

 

    Pyrogen (USP)

 

    Sterility (USP/EP)

 

    Bioburden (A0736/A0743)

 

    Amgen will provide consulting for the transferred A-100 Leptin analytical methods during their implementation by Amylin/CMOs/Amylin contractors.

 

    Amgen will review the method qualification/characterization protocols and reports, but will not provide the experimental design for the qualification/characterization.

 

    Method transfers may be required for different CMO sites for Drug Substance and Drug Product.

 

    Amgen will transfer methods to one (1) designated CMO site for each of Drug Substance and Drug Product.

 

    Amylin or its designated CMO will be responsible for additional method transfers.

 

    Amgen will write the method transfer protocols and will transfer these protocols to the CMO. The CMO will execute the method transfer protocols and author the method transfer reports. Amylin and Amgen will approve the method transfer reports authored by the CMO.

Drug Substance Technical Knowledge and Documentation

 

    Amgen will transfer the A-100 Leptin Manufacturing Process that was last run in LakeCentre, including:

 

    Process descriptions (process transfer documents, including electronic and hard copy of all of the current versions of the manufacturing batch records).

 

    Development reports where available.

 

    Copies of lab notebooks where no report exists.

 

    Copies of campaign summaries for the last LakeCentre campaign (including all the manufacturing batch records including process chromatograms and in-process data) and, where available, campaign summaries for any other campaign.

 

    Product quality summaries (test results, including release and stability results, chromatograms, pictures of gels, etc., system suitability data for each run, Certificates of Analyses (C of As), etc.).

 

    Analytical method descriptions (including electronic and hard copy of the controlled document for each method),


THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

    Amgen and Amylin will evaluate any process improvements and determine if any should be incorporated.

 

    Amgen will perform at least three successful bench/pilot runs at Amgen to show process reproducibility. Amylin and/or the bulk CMO will be allowed to observe the runs. Success will be defined as meeting all product specifications (analytical testing performed by Amgen) consistent with current (as of Effective Date) clinical material of A-100 Leptin, yield > 5g/L for fermentation titer, and an overall purification yield > 11 % (within three (3) sigma of last LakeCentre campaign).

 

    Amgen will review the characterization protocols and reports, but will not provide the experimental design for the characterization.

 

    Amgen will also transfer the A-200 Leptin Manufacturing Process documentation, but such transfer will be solely limited to supplying Amylin with Amgen’s existing technical documentation (which will, if possible, include the master and working cell banks and will at least include a research cell bank), supporting written documentation and data, including the following:

 

    Process descriptions (process transfer document).

 

    Development reports where available.

 

    Copies of campaign summaries where available.

 

    Product quality summaries (test results, C of As, etc).

 

    Analytical method descriptions.

 

    Batch records.

 

    For Drug Substance, Amgen will be responsible for the transfer through the successful completion of runs at the CMO, which will be defined as a maximum of three pilot runs at an appropriate scale as recommended by Amgen and that meet product specifications consistent with current (as of Effective Date) clinical material of A-100 Leptin, yield > 5g/L for fermentation titer, and an overall purification yield > 11% (within three (3) sigma of last LakeCentre campaign).

 

    Amgen will be responsible for product specification testing for material manufactured during the CMO pilot runs.

 

    Failure to meet acceptance criteria due to environmental factors at the CMO facility (i.e. bacterial contamination, high endotoxin, yield loss due to an assignable cause) will not be considered a failure if there is an assignable root cause.

Drug Product Technical Knowledge and Documentation

 

    Amgen will transfer the A-100 Leptin fill-and-finish lyophilization process currently run at ATO-B20 (Amgen Clinical Manufacturing), including:

 

    Process descriptions (including electronic and hard copy of the latest revision of the manufacturing batch record and the last batch record that was run at Parke-Dale, LakeCentre or Amgen’s pilot plant and any available campaign summary reports (or data if no such report is available) from such work).


THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

EXCHANGE COMMISSION.

 

    Development reports where available.

 

    Copies of lab notebooks where no report exists.

 

    Manufacturing Procedures and Master Packaging Configurations.

 

    Amgen is transferring the process and formulation “as is” and will not do any additional development work on the process prior to the transfer (except as expressly provided herein).

 

    CMO for Drug Substance manufacture may be a different site and/or company than that used for manufacture of Drug Product.

 

    Amgen will review the characterization protocols and reports written by Amylin/CMO but will not provide the experimental design for the characterization.

 

    Drug Product transfer will not require additional pilot fills beyond the current ATO-B20 scheduling. Amylin/CMO will be invited to come to ATO, at Amylin/CMO’s own costs and expenses, to observe no more than four fill runs in B20 during 2006 at a time mutually convenient for both Parties. Any such observation will not occur prior to May, 2006 and will require at least three weeks prior notice to Amgen. Each observation will be limited to two persons and viewing of aseptic activities will occur behind glass. Amgen will provide certain analytical testing as provided in Section 3.4 of this Agreement.

 

    For Drug Product, Amgen will be responsible for the transfer through the successful completion of runs at the CMO, which will be defined as a maximum of three runs at an appropriate pilot scale as recommended by Amgen and that meet product specifications consistent with current (as of Effective Date) clinical material of A-100 Leptin.

 

    Amgen will be responsible for product specification testing for material manufactured during the CMO pilot runs.

 

    Failure to meet acceptance criteria due to environmental factors at the CMO facility (i.e. bacterial contamination, high endotoxin) will not be considered a failure if there is an assignable root cause.

 

    Amgen will transfer the fill-and-finish lyophilization process for the leptin placebo drug product.

Stability and Reference Standard

 

    Amgen will transfer active stability studies (e.g. protocols, data, samples), and protocols and data from completed or suspended studies.


THIS EXHIBIT HAS BEEN REDACTED AND IS THE SUBJECT OF A

CONFIDENTIAL TREATMENT REQUEST. REDACTED MATERIAL IS MARKED

WITH [*] AND HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND

EXCHANGE COMMISSION.

 

    Amgen will transfer reference standard material, including qualification data and characterization data. Amgen will supply all existing inventory of reference standard in addition to production and testing/release of a new lot of reference standard.

 

    It will be the responsibility of Amylin to make additional reference standard material as and when needed.

Technical Support

 

    Amgen is not responsible for the success of commercialization or runs after pilot runs.

 

    Amgen’s role in the transfer process with respect to a CMO will be limited to a consulting role after the pilot runs at such CMO.

 

    Consulting will be limited to reasonable requests for review of process data, batch documentation, process characterization plans, process validation protocols and reports and one onsite visit during the engineering and conformance runs to observe critical operations.

 

    Consulting does not include any lab work in either Party’s analytical or process labs.

 

    Amgen will perform such consulting activities, upon Amylin’s reasonable request, until the earlier of (i) twenty-four (24) months after the completion of the Drug Substance pilot runs at the designated CMO, or (ii) December 31, 2008.

 

    Amylin will provide to Amgen a timeline through regulatory approval and an estimate of requirements for Amgen consulting services upon completion of each of the three transfer activities set forth in Section 5.2(a)(i).

 

    Amgen will need to approve all access of the CMOs or Amylin staff to Amgen’s facilities and technology during the technology transfer. Approval is at Amgen’s sole discretion (subject to compliance with the technology transfer obligations of this Agreement).

 

    Amgen will supply a list of all critical equipment to perform both processes to aid in selection of the appropriate CMOs.

 

    Amylin will be responsible for negotiating and entering into, and performing under, the contract with the selected CMOs.

body or regulatory authority with respect to such Patented Product in such country, or (c) expiration of any data exclusivity period granted by a governmental body or regulatory authority with respect to such Patented Product in such country, and in the case of clause (c) above, only for so long as the total number of units of a Patented Product sold in a calendar quarter exceeds the total number of units of generic products (corresponding to the Patented Product) sold in the same calendar quarter (hereinafter the “Royalty Term”); provided that, with respect to Patented Products which are designated as Orphan Products in the United States, such data exclusivity period shall be deemed to be twelve (12) years from the date of U.S. FDA marketing approval thereof, and that, with respect to Patented Products which are not designated as Orphan Products in the United States, such data exclusivity period shall be deemed to be the data exclusivity period then in effect in the United States at the time of U.S. FDA approval of the applicable Patented Product. For purposes of this paragraph, “data exclusivity” means that neither the generic drug or biologic applicant nor the applicable governmental body or regulatory authority with respect to a particular country may refer or actually refers to, or may rely or actually relies on, the information of the original marketing authorization holder for the corresponding branded drug or biologic product (in this case, the applicable Patented Product).

4. Paragraph 6.2 of the Rockefeller/Amgen License Agreement is replaced in its entirety with the following new Paragraph 6.2:

 

“6.2 The obligation to pay royalties hereunder is imposed only once with respect to the sale of a Product regardless of the number of patent claims within the Licensed Patent Rights which cover such Product.”

5. Paragraph 6.5 of the Rockefeller/Amgen License Agreement is replaced in its entirety with the following new Paragraph 6.5:

 

“6.5 Rockefeller agrees to use reasonable efforts, short of litigation, to resist any claim by a third party which might affect the exclusive nature of any license granted hereunder. In the event that during the term of this Agreement the license granted herein is rendered non-exclusive in any country of the Territory as a result of any governmental, judicial, or other action, then the royalty provided in Subparagraph 6.1(c) hereof due to Rockefeller on the affected Product(s) in that country shall be reduced by [*]. In such case, the obligation to pay Rockefeller a royalty on the affected Product(s) pursuant to Subparagraph 6.1(c) in that country shall expire/terminate no later than [*] from the date of first commercial sale of the affected Product(s) in that country. Thereafter, the license granted under this Agreement with respect to such affected Product(s) in such country shall be fully paid up.”

“7.6 This Agreement shall expire with respect to Patented Product for which Amylin has a license under the Amgen/Amylin License Agreement upon (i) the expiration of the last Royalty Term for such Patented Product, or (ii) if the Amgen/Amylin License Agreement is terminated earlier in accordance with the termination provisions therein, such earlier termination date. Thereafter, except in the case of termination by Rockefeller based on Amylin’s uncured material breach, the license granted under this Agreement, and the sublicense granted to Amylin under the Amgen/Amylin License Agreement, with respect to such Patented Product in such country shall be fully paid up and irrevocable.”

7. Paragraph 1.3 of the Rockefeller/Amgen License Agreement is replaced in its entirety with the following new Paragraph 1.3:

 

“1.3 “Commercially Reasonable Efforts” means the level of efforts and resources commonly used in the pharmaceutical industry to develop, obtain regulatory approvals for, protect intellectual property relating to, and commercialize a product consistent with the efforts a similarly situated biopharmaceutical company would typically devote to a product at a similar stage in its product life and of similar market potential, profit potential and strategic value resulting from its own research efforts, based on information and conditions then-prevailing, including, without limitation, efficacy of the product, the competitiveness of alternative products in the marketplace, the patent and other proprietary position of the product, the likelihood of regulatory approval given the regulatory structure involved and the likelihood of adequate reimbursement. Commercially Reasonable Efforts shall be determined on a country-by-country (each country including its territories) basis for a particular Licensed Product, and it is anticipated that the level of effort will change over time reflecting changes in the status of the Licensed Product and the country (including its territories) involved.”

8. Rockefeller hereby generally, irrevocably, unconditionally and completely releases, acquits and forever discharges Amylin and Amgen, and all agents, representatives, employees, officers, directors, attorneys, successors and assigns thereof, from any and all claims, causes of action, damages, losses, attorneys’ fees, costs, whether known or unknown, suspected or unsuspected, matured or unmatured, of every kind and nature, at law or in equity, arising from or relating to claims or potential claims regarding any obligation to undertake to use Commercially Reasonable Efforts to identify, develop and market Product(s) under the Amgen/Rockefeller License Agreement prior to the date of this Letter Agreement. Rockefeller acknowledges and agrees that, notwithstanding any law, regulation, rule or order to the contrary, the foregoing release shall be effective whether or not such claims are currently known, unknown, foreseen, unforeseen, patent or latent, and whether or not Rockefeller becomes aware of facts in addition to or different from what is known to Rockefeller as of the date of this Letter Agreement.

9. Except as specifically amended by this Letter Agreement, the Amgen/Rockefeller License Agreement shall remain in full force and effect in accordance with its terms.
