Zosano Pharma Initiates Phase 2/3 Clinical Study in Cluster Headache

FREMONT, Calif., Oct. 24, 2019 (GLOBE NEWSWIRE) — Zosano Pharma Corporation (NASDAQ:ZSAN), a clinical-stage biopharmaceutical company, today announced that the company has begun enrolling cluster headache patients in the ATAC clinical trial. This Phase 2/3 study will evaluate the efficacy of C213 for the acute treatment of cluster headache. C213 is the company’s investigational proprietary formulation of zolmitriptan delivered utilizing its proprietary ADAM patch technology, which consists of titanium micro-projections coated with drug and is the same formulation as QtryptaTM, for the acute treatment of migraine.
“We are pleased to expand the application of our ADAM microneedle technology beyond our lead development indication for the acute treatment of migraine with this advanced stage clinical study in cluster headache,” said Dr. Don Kellerman, Vice President of Clinical Development and Medical Affairs. “This population suffers from excruciating and debilitating pain and has limited effective treatment options with no new FDA-approved drugs for the acute treatment of cluster headache since the 1990s. We are excited that the clinically significant pain freedom and relief observed in our migraine trial will potentially also be demonstrated in the cluster headache clinical trial.”Bob Wold, founder of Clusterbusters and a person who suffers from cluster headaches added, “We applaud Zosano’s focus on developing a new acute treatment option for patients who experience the deep and relentless pain associated with cluster headache. I believe Zosano’s C213 drug candidate represents a patient-friendly therapeutic patch that has potential to rapidly and significantly reduce cluster headache pain over a sustained period. If proven successful in this late stage trial, C213 could be a very attractive therapeutic option for our community.”Zosano has begun enrolling patients in its Phase 2/3 study, in which approximately 120 adults who suffer from cluster headache will be randomized to receive 1.9 mg of C213, 3.8 mg of C213, or placebo in a 1:1:1 fashion. The co-primary endpoints of the study are the proportion of patients who achieve pain relief at 15 minutes and the proportion of patients whose pain relief is sustained from 15 minutes to 60 minutes.About Cluster Headache
Cluster headache is an under-recognized and often misdiagnosed, debilitating neurological condition characterized by severe unilateral temporal and orbital pain. These excruciating attacks can last from 15 minutes to 3 hours and can occur up to eight times a day, are often described by cluster patients as the worst pain they have ever experienced, resulting in suicidal ideations in 15 to 22 percent of patients. Over 300,000 people in the United States suffer from cluster headache.
