Zosano Announces Publication of Most Bothersome Symptom Data from the ZOTRIP Pivotal Study in Headache: The Journal of Head and Face Pain

FREMONT, Calif., May 23, 2018 (GLOBE NEWSWIRE) -- Zosano Pharma Corporation (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 Headache, the Journal of Head and Face Pain, has published the post-hoc analysis on the use of most bothersome symptom (MBS) as a co-primary endpoint from the Company’s ZOTRIP pivotal study.

Headache published the paper titled “Use of Most Bothersome Symptom as a Coprimary Endpoint in Migraine Clinical Trials: A Post-Hoc Analysis of the Pivotal ZOTRIP Randomized, Controlled Trial”. The paper analyzes the positive MBS results from Zosano’s ZOTRIP pivotal study, a multi-center, double-blind, placebo-controlled trial demonstrating the efficacy and safety of M207, Zosano’s novel proprietary formulation of zolmitriptan using its ADAM technology.  The ZOTRIP pivotal study, evaluating ADAM zolmitriptan for the acute treatment of migraine, was one of the first large studies to incorporate MBS freedom and pain freedom as co-primary endpoints, per recently issued guidance by the US Food and Drug Administration.  MBS freedom at two hours was observed in 68% of M207 3.8 mg subjects as compared to 43% of placebo subjects (P < .01).

“We are pleased to see this aspect of the ZOTRIP pivotal study published and hope that the results and discussion will be helpful to others designing and interpreting trials of acute treatment of migraine,” said Dr. Don Kellerman, Vice President of Clinical Development.  “Since the time of our manuscript submission, several other trials have reported results using these coprimary endpoints, and we look forward to their publication.”

About M207

M207 is our proprietary formulation of zolmitriptan delivered utilizing Zosano's proprietary 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 pivotal study, 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.  In November 2017, the Company announced the initiation of its long-term safety study evaluating M207 and expects to file an NDA for M207 in the fourth quarter of 2019.
