FREMONT, Calif., Jan. 05, 2017 (GLOBE NEWSWIRE) -- Zosano Pharma Corporation (NASDAQ:ZSAN), an emerging CNS company focused on providing rapid symptom relief to patients using the Company’s proprietary intracutaneous delivery system, today announced that the last subject has been treated in the Company’s registration-enabling, pivotal efficacy trial (the Zotrip trial), of M207 for the treatment of migraine.
“Having reached this milestone for the Zotrip study reinforces our expectation that top-line data will be reported in the first quarter of 2017 as planned,” commented Konstantinos Alataris, PhD, President and Chief Executive Officer of Zosano Pharma. “On behalf of the entire management team, I would like to extend our sincere appreciation to Zotrip’s investigators and study participants for their shared commitment to finding improved treatment options for those suffering with migraine.”
The Zotrip pivotal efficacy trial is a multicenter, double-blind, randomized, placebo-controlled trial comparing three doses of M207 (1.0 mg, 1.9mg, and 3.8mg) to placebo for the treatment of a single migraine attack. Subjects were enrolled in the Zotrip trial at 36 centers across the United States. Subjects recruited into the Zotrip trial had a history of at least one year of migraine episodes with or without aura. Upon recruitment, the subjects entered a run-in period that ensured they met the key eligibility criteria of 2-8 migraine attacks per month, which was documented using an electronic diary. Successfully screened subjects were then randomized into the treatment/dosing period in which they had 8 weeks to confirm and receive blinded treatment for a single migraine attack.
The co-primary endpoints of this study are:
- proportion of subjects with pain freedom at 2 hours post-dosing, and
- proportion of subjects with freedom from their most bothersome symptom at 2 hours post-dosing. These symptoms include photophobia, phonophobia or nausea, pre-specified by each subject.
A key secondary endpoint of this trial is pain relief at 30 min, aimed at demonstrating the rapid relief profile of M207.
These endpoints were chosen after the Company’s discussions with the Food and Drug Administration (FDA), and meet all criteria set forth by the FDA’s October 2014 Guidance Document —“Migraine: Developing Drugs for Acute Treatment.”
The FDA has indicated that a single, positive, pivotal efficacy study, in addition to a safety study, will be sufficient for approval under a 505(b)(2) pathway. The Company intends to conduct the safety study after completion of the Zotrip trial.
About M207
M207 is Zosano’s proprietary zolmitriptan-coated microneedle patch that is designed to rapidly deliver zolmitriptan during a migraine attack. In a phase 1 trial, M207 demonstrated markedly faster absorption kinetics compared to oral zolmitriptan. The Company 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.
