ZOSANO PHARMA CORPORATION (NASDAQ:ZSAN) Files An 8-K Other Events

On March 4, 2020, Zosano Pharma Corporation (the \”Company\”) announced that the U.S. Food and Drug Administration (the \”FDA\”) accepted the Company’s New Drug Application (the \”NDA\”) for Qtrypta™ for filing and substantive review.

The Prescription Drug User Fee Act goal date for the completion of the FDA’s review of Qtrypta™ is set for October 20, 2020. This date reflects a standard 10-month review period and is consistent with the review timeline for a 505(b)(2) NDA submission.

The NDA is supported by the clinical results of the ZOTRIP pivotal Phase 2/3 clinical study, which evaluated the efficacy, safety and tolerability of Qtrypta™ compared to placebo. A total of 41.5% of patients treated with the 3.8 mg dose of Qtrypta™ achieved pain freedom at 2 hours and 68.3% reported freedom from most bothersome symptom also at 2 hours, both of which were co-primary endpoints. Additionally, 80.5% of patients reported pain relief at 2 hours, a secondary endpoint. The results of the study were published in Cephalalgia in October 2017.

A post-hoc analysis showing that Qtrypta™ reduced pain in subjects with difficult to treat migraine attacks was published in Headache: The Journal of Head and Face Pain in February 2019.

Additionally, in the Phase 3 long term safety study, the most frequently reported adverse event was redness at the application site. Of these adverse events, 95% were reported as mild, and more than 80% resolved within 48 hours. Less than 2% of patients reported triptan-like neurological side effects typically found in the class, such as dizziness and paresthesia.

About ZOSANO PHARMA CORPORATION (NASDAQ:ZSAN)

Zosano Pharma Corporation is a clinical-stage specialty pharmaceutical company.

Its microneedle patch system offers consistent drug delivery and improved ease of use and room-temperature stability. The Company’s short-wear-time transdermal patch consists of an array of titanium microneedles that is coated with its formulation of an approved drug and attached to an adhesive patch. When the patch is applied with its hand-held applicator, the microneedles painlessly penetrate the skin, resulting in rapid dissolution and absorption of the drug coating through the capillary bed. Its product candidates include ZP-Triptan, ZP-Glucagon and ZP-PTH. ZP-PTH is a formulation of teriparatide, a synthetic form of parathyroid hormone. ZP-Glucagon is a formulation of glucagon.
