• Completed enrollment for our M207-ADAM study with 344 subjects
  
• Presented additional analyses from the ZOTRIP pivotal study on pain relief and recurrence at the 2018 American Headache Society (AHS) meeting
• Published M207 nonclinical data in multiple leading scientific journals

FREMONT, Calif., Aug. 09, 2018 (GLOBE NEWSWIRE) -- Zosano Pharma Corporation (NASDAQ:ZSAN), a clinical-stage biopharmaceutical company, developing and commercializing therapies that deliver rapid systemic absorption by leveraging its novel and proprietary technology called Adhesive Dermally-Applied Microarray (“ADAM™”), today announced financial results for the second quarter ended June 30, 2018.

“In the second quarter, enrollment was completed for the M207-ADAM study, a long-term safety study for the acute treatment of migraine. Since study initiation in November 2017, a total of 344 subjects have been enrolled in the study and received M207. The open-label study, designed in consultation with the FDA will evaluate at least 150 subjects for six months and at least 50 subjects for a year,” commented John Walker, Chairman and Chief Executive Officer. “We are pleased with the observed data from the study thus far, which illustrates that the ADAM patch is reported to be well-tolerated by subjects after multiple applications for their migraines. Additionally, there have been no drug related serious adverse events reported to date. Importantly, efficacy based on the secondary measures of observed pain freedom at two hours and pain relief at two hours remain consistent with earlier clinical studies at 42% response rate and 84% response rate, respectively.”

“In the second quarter, we continued to grow our body of evidence supporting the development and potential commercialization of M207. Analyses from the M207 Phase 2/3 clinical study on pain relief by time and recurrence of migraine in subjects with pain relief at two hours were presented at the American Headache Society (AHS) meeting in June. The data showed M207 demonstrated both early and durable responses in the treatment of migraine,” Mr. Walker continued. “During AHS, there was also a poster and oral presentation on key findings for receptor binding kinetics of zolmitriptan and sumatriptan. These findings showed differences between the two compounds, with zolmitriptan having a longer duration of receptor occupancy, providing a potential mechanistic rationale for the durability of effect seen in the ZOTRIP Study.”

• In May 2018, Zosano announced the appointment of Steven A. Elms to the Board of Directors. Mr. Elms is a seasoned investment executive with extensive experience in M&A, financings, investment banking and capital market transactions.

• In June 2018, Zosano presented at the 2018 American Headache Society (AHS) meeting additional analyses from the ZOTRIP pivotal study on pain relief and recurrence, demonstrating both early onset and durability of effect.
• In June 2018, the Journal of Pharmaceutics published positive data from a nonclinical study evaluating pharmacokinetics and skin tolerability for ADAM™ technology for the delivery of zolmitriptan.
• In July 2018, the Journal of Pharmaceutical Science published skin tolerability and bioavailability data using ADAM’s intracutaneous zolmitriptan delivery. The pharmacokinetic studies showed that the ADAM 1.9-mg zolmitriptan was delivered with high efficiency (85%) and high absolute bioavailability (77%).

Financial Results for the Second Quarter Ended June 30, 2018

• Zosano reported a net loss of $8.8 million, or $0.75 per share on a basic and diluted basis, and $17.0 million, or $2.47 per share on a basic and diluted basis, for the three and six months ended June 30, 2018, respectively, compared to a net loss of $6.7 million, or $3.44 per share on a basic and diluted basis, and $13.7 million, or $9.22 per share on a basic and diluted basis, for the same periods in 2017.
  
  
• Research and development expenses were $6.5 million and $12.3 million for the three and six months ended June 30, 2018, respectively, compared to $4.4 million and $9.0 million for the same periods in 2017. The increase in research and development expenses was primarily attributable to an increase in clinical trial costs related to the M207-ADAM study and to support production of the registration batches.
  
  
• General and administrative (G&A) expenses were $2.3 million and $4.5 million for the three and six months ended June 30, 2018, respectively, compared to $2.2 million and $4.3 million for the same period in 2017. The increase in general and administrative expenses was due to the increased rent, franchise taxes, and other general corporate activities.

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. The drug-coated microneedles physically break through the stratum corneum and penetrate into the epidermis and dermis, where the dry drug coating is dissolved by the surrounding skin interstitial fluid. 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 anticipates filing an NDA for M207 in the fourth quarter of 2019.
