ZSAN Zosano Pharma Corporation

Zosano Pharma Corporation (NASDAQ:ZSAN), a clinical-stage biopharmaceutical company, today announced the successful formulation of a COVID-19 vaccine candidate, obtained from a vaccine developer, utilizing Zosano’s microneedle patch system. Zosano’s patch consists of an array of approximately two thousand drug-coated titanium microneedles mounted on an adhesive patch that is administered to the skin using a reusable applicator.

“We are pleased to have successfully formulated a COVID-19 vaccine candidate onto our microneedle patch system, which provides additional support for the potential of our microneedle patch technology,” said Mahmoud Ameri, Ph.D., vice president of research and development at Zosano. “We believe a COVID-19 vaccine candidate using our patch technology, if successfully developed and approved, may provide an alternative to traditional intramuscular injections. The formulated patches are also designed to be stable at room temperature, which we believe may enable easier and broader distribution without the burden of cold-chain storage.”

“This successful development milestone along with previously published data on the formulation and coating of an influenza vaccine on our transdermal patch is encouraging for the broader applicability of Zosano’s technology,” said Steve Lo, chief executive officer of Zosano. “While we continue to be focused on the potential resubmission of our M207 New Drug Application, we also continue to pursue non-dilutive and partnership opportunities to expand the potential use of our technology.”
