Phathom Pharmaceuticals issued a press release titled “Phathom Pharmaceuticals Reports Second Quarter 2022 Financial Results and Provides Business Updates” on August 2, 2022, prior to market hours. The press release disclosed that during post-approval testing for the commercial launch of their vonoprazan drug product, the company found trace levels of a nitrosamine impurity. Phathom is currently collaborating with the FDA to implement an additional test method, specification, acceptable intake limit, and controls to address this issue before releasing their first vonoprazan-based products to the market. As a result, the VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK product launches will be delayed. This news caused Phathom’s stock price to drop by 28% or $2.61 per share to close at $6.46 per share on August 2, 2022.
