Zosano Pharma Announces Issuance of New U.S. Patent Covering M207 as an Acute Treatment for Migraine

FREMONT, Calif., March 02, 2018 (GLOBE NEWSWIRE) -- Zosano Pharma Corp. (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 the previously announced Notice of Allowance of our patent application titled "Method of Rapidly Achieving Therapeutic Concentrations of Triptans for Treatment of Migraines" has resulted in the issuance of a U.S. patent 9,918,932.  The inventors were Dr. Mahmoud Ameri, Dr. Don Kellerman, Dr. Yi Ao, and Dr. Peter Dadonna, all of whom are current or former employees of Zosano.  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. The newly issued patent 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 pleased to have this important expansion of our patent estate for M207," said John Walker, Chairman and Chief Executive Officer of Zosano. "This issuance supports our intellectual property strategy for our ADAM technology, and specifically M207.  We intend to pursue similar patent coverage for future products that Zosano develops internally, and in future partnerships."

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 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 penetrating 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.
