Item 8.01. Other Events.

On November 18, 2015, BIND Therapeutics, Inc. (the “Company”) announced that AstraZeneca AB (“AstraZeneca”) has initiated patient dosing in a phase 1 clinical trial of AstraZeneca’s Accurin AZD2811, an Aurora B Kinase inhibitor, in solid tumors (the “Phase 1 Trial”). Under terms of the collaboration agreement between the Company and AstraZeneca, the Company earned a $4.0 million clinical milestone payment upon the first dosing of a patient in the Phase 1 Trial.

Based on the $4.0 million AstraZeneca clinical milestone payment, the previously announced $2.5 million Pfizer option exercise fee and anticipated R&D reimbursement for the next stage of the Pfizer collaboration, the Company reiterates that it expects its cash, cash equivalents and short-term investments to fund operating expense and capital expenditure requirements into the fourth quarter of 2016. This expectation is based on the Company’s current operating plans and research and development funding that it expects to receive under its existing collaborations, but excludes any potential milestone payments under its collaboration agreements.

Forward-Looking Statements

This Current Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this Current Report that do not relate to matters of historical fact should be considered forward-looking statements, including without limitation statements regarding the sufficiency of the Company’s cash, cash equivalents and short-term investments.

These forward-looking statements are based on management’s current expectations. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause the Company’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following: the fact that the Company has incurred significant losses since its inception and expects to incur losses for the foreseeable future; the Company’s need for additional funding, which may not be available; raising additional capital may cause dilution to its stockholders, restrict its operations or require it to relinquish rights to its technologies or drug candidates; the Company’s limited operating history; the terms of the Company’s credit facility place restrictions on its operating and financial flexibility; the Company’s inability to utilize its net operating loss carryforwards and certain other tax attributes; failure to use and expand its medicinal nanoengineering platform to build a pipeline of drug candidates and develop marketable drugs; the early stage of the Company’s development efforts with only BIND-014 and AZD2811 in clinical development; failure of the Company or its collaborators to successfully develop and commercialize drug candidates; clinical drug development involves a lengthy and expensive process, with an uncertain outcome; delays or difficulties in the enrollment of patients in clinical trials; serious adverse or unacceptable side effects or limited efficacy observed during the development of the Company’s drug candidates; inability to maintain any of the Company’s collaborations, or the failure of these collaborations; the Company’s reliance on third parties to conduct its clinical trials and manufacture its drug candidates; the Company’s inability to obtain required regulatory approvals; any conclusion by the FDA that BIND-014 does not satisfy the requirements for approval under the Section 505(b)(2) regulatory approval pathway; the fact that a fast track or breakthrough therapy designation by the FDA for the Company’s drug candidates may not actually lead to a faster development or regulatory review or approval process; the inability to obtain orphan drug exclusivity for drug candidates; failure to obtain marketing approval in international jurisdictions; any post-marketing restrictions or withdrawals from the market; failure to comply with anti-kickback, fraud and abuse and other healthcare laws and regulations; effects of recently enacted and future legislation; effects of strict price controls imposed by governments outside the United States; failure to comply with environmental, health and safety laws and regulations; failure to achieve market acceptance by physicians, patients, or third-party payors; failure to establish effective sales, marketing and distribution capabilities or enter into agreements with third parties with such capabilities; effects of substantial competition; unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives; product liability lawsuits; failure to retain key executives and attract, retain and motivate qualified personnel; difficulties in managing the Company’s growth; risks associated with operating internationally, including the possibility of sanctions with respect to our operations in Russia; the possibility of system failures or security breaches; failure to obtain and maintain patent protection for or otherwise protect our technology and products; effects of patent or other intellectual property lawsuits; the volatility of the price of the Company’s common stock, which could result in substantial losses for its stockholders; significant costs and required management time as a result of operating as a public company; and any securities class action litigation. These and other important factors discussed under the caption “Risk Factors” in the Company’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission, or SEC, on November 2, 2015, and the Company’s other reports filed with the SEC could cause actual results to differ materially from those indicated by the forward-looking statements made in this Current Report. Any such forward-looking statements represent management’s estimates as of the date of this Current Report. While the Company may elect to update such forward-looking statements at some point in the future, the

Company disclaims any obligation to do so, even if subsequent events cause the Company’s views to change. These forward-looking statements should not be relied upon as representing the Company’s views as of any date subsequent to the date of this Current Report.
