Shares of Pharvaris NV (NASDAQ:PHVS) fell 34% Aug. 22 to close at $12.15 after the company reported the U.S. FDA placed a clinical hold on PHA-121, its oral bradykinin B2-receptor antagonist for hereditary angioedema (HAE), citing a review of nonclinical data. PHA-121, which goes after the same target as well-established injectable HAE drug Firazyr (icatibant, Takeda Pharmaceutical Co. Ltd.), is the active ingredient in Pharvaris’ two lead programs: PHVS-416, a softgel capsule formulation, and PHVS-719, an extended-release tablet formulation.
