Migraine drug developer Zosano’s value more than halved after filing for bankruptcy – Endpoints News


Public procurement devastation and repeated rejections by the FDA have added a bleak future for Zosano Pharma as it appears the 16-year biotech journey is coming to an end.

The Fremont, Calif.-based biotech filed for bankruptcy on Wednesday and is currently operating as a ‘debtor in possession’ and intends to dispose of ‘substantially all of its assets’ during the chapter deal. 11, Zosano said Thursday morning.

Kaleido Biosciences, the pioneer-founded flagship microbiome biotech, closed in April and Orphazyme sold itself with the help of the Danish courts last month.

And, further cementing a cloudy future for Zosano, biotech vice president of clinical development and medical affairs Donald Kellerman has left the company, effective June 1.

After getting the FDA’s rejection a few years ago for its potential migraine drug, Zosano tried to resubmit, but the FDA again had disagreements over the drug. In April, the agency granted the company a 12-month extension to resubmit the NDA for M207, but Zosano said that month it would suspend the program to preserve cash.

As of April 26, Zosano had about $11.4 million in cash and cash equivalents and was working with financial adviser SierraConstellation Partners to determine the future of his assets.
