Zosano Pharma, (NASDAQ:ZSAN) ("Zosano" or the "Company") a clinical stage biopharmaceutical company focused on providing rapid systemic administration of therapeutics to subjects using its proprietary Adhesive Dermally-Applied Microarray ("ADAM") technology, today announced that it has received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for a patent application titled "Method of Rapidly Achieving Therapeutic Concentrations of Triptans for Treatment of Migraines".  In February 2017, Zosano reported positive pivotal data from our Zotrip Phase 2/3 trial, in which subjects treated with the 3.8mg dose of M207 achieved statistical significance on the co-primary endpoints. This newly-allowed patent application contains claims generated from formulation, preclinical and clinical studies, and highlights the unique aspects of the Zosano technologies and their applicability for treatment of migraine.

"We are extremely pleased with this expansion of the patent estate for M207," said John Walker, Chairman and Chief Executive Officer of Zosano. "This allowance expands the breadth of and further validates our intellectual property portfolio for our ADAM technology, and specifically M207. It covers method of use, formulation, delivery system, pharmacokinetic profile and the pharmacodynamic response."

Zosano’s patent estate additionally includes other granted U.S. and foreign patents and pending patent applications covering our ADAM technology, including our microneedle technology, drug formulations, methods of use and applicators.  
  
About Migraine

Migraine is the leading cause of disability among neurological disorders in the United States according to the American Migraine Foundation. Migraine symptoms can include moderate to severe headache pain combined with nausea and vomiting, or abnormal sensitivity to light and sound.  According to the Migraine Research Foundation, migraine affects 30 million men, women and children in the United States. Most migraines last between four and 24 hours, but some last as long as three days. According to published studies, 63% of migraine patients experience between one and four migraines per month. According to Decision Resources, prescription drug sales for migraine in the top seven countries were estimated to be $3.3 billion in 2015, and are expected to grow to $4.4 billion in 2020. Triptans, a family of tryptamine-based drugs first sold in the 1990s, account for almost 75% of anti-migraine therapies prescribed at office visits.

About M207

M207 is our proprietary formulation of zolmitriptan delivered utilizing Zosano’s proprietary Adhesive Dermally-Applied Microarray, or ADAM technology.  Zosano’s ADAM technology consists of titanium microprojections coated with drug, and in the case of M207, our formulation of zolmitriptan.  Our ADAM technology delivers drug by abrading the stratum corneum and allowing drug to be absorbed into the microcapillary system of the skin.  In February 2017, the Company announced statistically significant results from the ZOTRIP trial, which demonstrated that the 3.8mg dose of M207 met both co-primary endpoints, achieving pain freedom and most bothersome symptom freedom at 2 hours.
