FREMONT, Calif., July 25, 2016 (GLOBE NEWSWIRE) -- Zosano Pharma Corporation (NASDAQ:ZSAN), an emerging CNS company focusing on providing rapid symptom relief to patients using the Company’s proprietary transdermal delivery system, today announced the dosing of its first subject in its registration-enabling pivotal efficacy trial (the Zotrip trial), of its M207 patch, formerly known as ZP-Triptan, for the treatment of acute migraine.
“I’m extremely pleased to announce our first subject treated in the Zotrip trial. We are pleased with enrollment to date and reiterate that trial results are expected to be reported in the first quarter of 2017,” commented Konstantinos Alataris, PhD, President and Chief Executive Officer of Zosano Pharma. To date, 136 subjects have enrolled in the trial, 109 of which are in the run-in phase, and 7 subjects have been randomized.
M207 is Zosano’s proprietary zolmitriptan-coated microneedle patch that is designed to rapidly deliver zolmitriptan during a migraine attack. In a recently completed phase I trial, M207 demonstrated markedly faster absorption kinetics compared to oral zolmitriptan. The Company recently presented these results at the 2016 annual meeting of the American Headache Society. The Company believes M207’s injection-free mode of delivery has the potential to provide an attractive solution for acute migraine sufferers.
The ongoing Zotrip trial is a multicenter, double-blind, randomized, placebo-controlled trial comparing three doses of M207 (1.0 mg, 1.9 mg, and 3.8 mg) to placebo for the treatment of a single migraine attack. Three hundred sixty subjects are expected to be treated in the Zotrip trial at approximately 35 centers across the United States. Subjects are recruited into the Zotrip trial if they have a history of at least one year of episodic, acute migraines with or without aura. Upon recruitment, subjects undergo a screening and run-in period to ensure they meet the key eligibility criterion of 2-8 migraine attacks per month, documented using an electronic diary. Successfully screened subjects are then randomized into the treatment/dosing period and have 8 weeks to confirm and receive blinded treatment for a single migraine attack. Today’s announcement marks the commencement of the dosing/treatment phase of the Zotrip trial.
Based on the Company's discussions with the FDA and the FDA's October 2014 Draft Guidance--"Migraine: Developing Drugs for Acute Treatment," the co-primary endpoints of this study are:
(i) pain freedom at 2 hours post-dosing, and
(ii) freedom from each subject's most bothersome symptom at 2 hours post-dosing.
Furthermore, the FDA has indicated that a single, positive, pivotal efficacy study, in addition to a safety study, will be sufficient for approval under the 505(b)(2) pathway. The Company intends to conduct the safety study after completion of the Zotrip trial.
