NuPathe Announces First Quarter 2013 Financial Results and Operational Highlights

CONSHOHOCKEN, PA — May 14, 2013 — NuPathe Inc. (NASDAQ: PATH) today announced financial results for the quarter ended March 31, 2013, as well as recent operational highlights.

“Approval of ZECUITY was a significant milestone for NuPathe as a company and offers a new treatment option for migraine patients, especially the millions of patients who suffer from migraine-related nausea in addition to their headache pain,” said Armando Anido, chief executive officer of NuPathe. “We remain focused on securing commercial partners and preparing for the launch of ZECUITY, which remains on track for the fourth quarter of 2013.”

Quarterly and Recent Highlights

·                  In January, the U.S. Food & Drug Administration (FDA) approved ZECUITY® (sumatriptan iontophoretic transdermal system) for the acute treatment of migraine with or without aura in adults.  ZECUITY is a single-use, battery-powered patch that actively delivers sumatriptan, the most prescribed migraine medication, through the skin. As the first and only prescription migraine patch, we believe ZECUITY will be an attractive treatment option for millions of migraine patients, especially those who experience migraine-related nausea (MRN) with their attacks.

·                  In connection with the approval of ZECUITY, four of NuPathe’s patents were listed in the FDA’s Orange Book.  Based on these patents, NuPathe expects product exclusivity for ZECUITY into April 2029.

·                  In February, the automatic conversion of our Series A Preferred Stock was triggered, resulting in the conversion of 100% of the outstanding Series A Preferred Stock into common stock, as well as the termination of the “full ratchet” anti-dilution feature of the warrants we issued in connection with the Series A Preferred Stock in October 2012.

·                  In April and May, the United States Patent and Trademark Office (USPTO) issued notices of allowance for U.S. Patent applications 12/074,101 and 11/784,526, respectively.  Both patent applications are entitled “Implants for the Treatment of Dopamine Associated States.” Once issued, the patents will provide protection for NP201, NuPathe’s long-term biodegradable ropinirole implant for the treatment of Parkinson’s disease, into July 2028 and October 2027, respectively.

First Quarter 2013 Financial Results

NuPathe reported a net loss of $17.7 million, or $0.68 per diluted share, for the first quarter of 2013, compared with a net loss applicable to common shareholders of $6.3 million, or $0.43 per diluted share, for the first quarter of 2012. The 2013 first quarter period included a $12.2 million non-cash charge, or $0.47 per diluted share, for the change in fair value of the warrants that were issued in October 2012. Total operating expenses for the first quarter of 2013 were $5.0 million, compared to $5.8 million in the first quarter of 2012.

Research and development expenses were $2.0 million in the first quarter of 2013, compared with $3.5 million in the first quarter of 2012. The decrease was largely attributable to higher expenses in the 2012 period for clinical and manufacturing related activities as the Company prepared for the Zecuity NDA resubmission, as well as reduced compensation expenses in the 2013 period due to fewer headcount. Selling, general and administrative expenses were $3.0 million in the first quarter of 2013, compared with $2.4 million for the same period in 2012. The 2013 period increase was primarily attributable to a $1.1 million increase in non-cash stock compensation expense, partially offset by lower headcount and reduced commercial operations expenses.

Net cash used in operating activities for the three months ended March 31, 2013 was $3.9 million, primarily the result of spending for normal operating activities and continued development of ZECUITY. During this period NuPathe also used $0.5 million of cash in investing activities and $0.1 million in financing activities.

As of March 31, 2013, NuPathe had $18.0 million in cash and cash equivalents and working capital of $14.2 million, compared with $22.6 million in cash and cash equivalents and working capital of $19.8 million as of December 31, 2012. Management estimates that the Company’s existing cash and cash equivalents will be sufficient to fund operations and debt service obligations into the fourth quarter of 2013.  The additional capital that the Company will require to launch ZECUITY and to fund operations and debt service obligations beyond that point will depend largely upon the timing, scope, terms and structure of a commercial partnership for ZECUITY. To meet its capital needs, the Company intends to raise additional capital through corporate collaborations, partnerships or other strategic transactions, debt or equity financings or other funding opportunities.  However, there is no assurance that the Company will be able to secure a commercial partner on acceptable terms, and additionally no assurance that additional required capital will be available when needed or on acceptable terms.

As of May 10, 2013, NuPathe had 31,072,196 common shares outstanding.

About ZECUITY

ZECUITY® (sumatriptan iontophoretic transdermal system) is indicated for the acute treatment of migraine with or without aura in adults. ZECUITY is a single-use, battery-powered patch applied to the upper arm or thigh during a migraine. Following application and with a press of a button, ZECUITY initiates transdermal delivery (through the skin), bypassing the gastrointestinal tract. Throughout the four-hour dosing period, the microprocessor within ZECUITY continuously monitors skin resistance and adjusts drug delivery accordingly to ensure delivery of 6.5 mg of sumatriptan, the most prescribed migraine medication in the U.S., with minimal patient-to-patient variability.

Important Safety Information

Patients should not take ZECUITY if they have heart disease, a history of heart disease or stroke, peripheral vascular disease (narrowing of blood vessels to your legs, arms, stomach or kidney), transient ischemic attack (TIA) or problems with blood circulation, uncontrolled blood pressure, migraines that cause temporary paralysis on one side of the body or basilar migraine, Wolff-Parkinson-White syndrome or other disturbances of heart rhythm. Very rarely, certain people, even some without heart disease, have had serious heart-related problems after taking triptans like ZECUITY.

Patients should not use ZECUITY if they have taken other migraine medications such as ergotamine medications or other triptans in the last 24 hours or if they have taken monoamine oxidase-A (MAO-A) inhibitors within the last 2 weeks.

Patients should not use ZECUITY during magnetic resonance imaging (MRI).

Patients should not use ZECUITY if they have an allergy to sumatriptan or components of ZECUITY or if they have had allergic contact dermatitis (ACD) following use of ZECUITY. If patients develop ACD, they should talk to their healthcare provider before using sumatriptan in another form.

ZECUITY, like other triptans, may be associated with a potentially life-threatening condition called serotonin syndrome, mainly when used together with certain types of antidepressants including serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs).

Patients should tell their healthcare provider before using ZECUITY if they have heart disease or a family history of heart disease, stroke, high cholesterol or diabetes; have gone through menopause; are a smoker; have had epilepsy or seizures or if they are pregnant, nursing or thinking about becoming pregnant.

The most common side effects of ZECUITY are application site pain, tingling, itching, warmth and discomfort. Most patients experience some skin redness after removing ZECUITY. This redness typically goes away in 24 hours.

Please see full Prescribing Information for ZECUITY.

Patients are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.FDA.gov/medwatch or call 1-800-FDA-1088.
