Zosano Pharma Completes Enrollment in Phase 2 Trial for ZP-Glucagon, Its Microneedle Patch for Treatment of Severe Hypoglycemia

FREMONT, Calif., June 23, 2015 (GLOBE NEWSWIRE) -- Zosano Pharma Corporation (Nasdaq:ZSAN), a clinical-stage specialty pharmaceutical company that has developed a proprietary transdermal microneedle patch system to deliver therapeutics conveniently through the skin for the treatment of a variety of indications, today announced that it has completed enrollment in its Phase 2 clinical trial of ZP-Glucagon, a novel investigational patch treatment for severe hypoglycemia in diabetics.

The trial was designed as a four-way cross-over study to investigate the safety and pharmacokinetics, as well as the efficacy to reverse insulin-induced hypoglycemia, of ZP-Glucagon versus intramuscular injections at two different dose levels. Adult participants diagnosed with type 1 diabetes were enrolled at two clinical sites.

"Completion of enrollment for the Phase 2 trial marks a major milestone for one of our key portfolio products. ZP-Glucagon, if approved by the U.S. Food and Drug Administration, may be a significant improvement over the currently marketed products for treatment of severe hypoglycemia, which often require a lay person to deliver an injection after a cumbersome preparation process," said Vikram Lamba, Chief Executive Officer of Zosano Pharma. "We anticipate announcing top-line data from the trial around September of this year."
