On October 21, 2020, Zosano announced receipt of a Complete Response Letter (“CRL”) from the FDA. According to Zosano, “[t]he CRL cited inconsistent zolmitriptan exposure levels observed across clinical pharmacology studies, which had been previously identified in the FDA’s discipline review letter received by the Company in September. Specifically, the CRL noted differences in zolmitriptan exposures observed between subjects receiving different lots of Qtrypta in the Company’s trials and inadequate pharmacokinetic bridging between the lots that made interpretation of some safety data unclear.”
Further, Zosano reported that “[t]he CRL referenced unexpected high plasma concentrations of zolmitriptan observed in five study subjects enrolled in the Company’s pharmacokinetic studies. The FDA recommended that the Company conduct a repeat bioequivalence study between three of the lots used during development. The NDA included data on a total of 774 subjects across 5 trials who were administered or dosed with Qtrypta.”
On this news, Zosano’s stock price fell $0.17 per share, or 27%, to close at $0.4441 per share on October 21, 2020.
