Two New Drug Applications (NDAs) for vonoprazan-based regimens for the treatment of H. pylori infection were submitted to the U.S. FDA in September 2021. Based on the positive PHALCON-EE trial, Phathom also plans to submit an NDA to the FDA for the healing of all grades of EE and relief of heartburn, and maintenance of healing of all grades of EE and relief of heartburn by the end of the first half of 2022.

About Vonoprazan
Vonoprazan is an investigational, oral small molecule potassium-competitive acid blocker (P-CAB). P-CABs are a novel class of medicines that block acid secretion in the stomach. Vonoprazan has shown the potential to have rapid, potent, and durable anti-secretory effects as a single agent in the treatment of gastroesophageal reflux disease (GERD) and in combination with antibiotics for the treatment of Helicobacter pylori (H. pylori) infection. The FDA has awarded qualified infectious disease product (QIDP) status and granted Fast Track designation to vonoprazan in combination with both amoxicillin and clarithromycin and with amoxicillin alone for the treatment of H. pylori infection. Phathom submitted NDAs in September 2021 to the FDA for vonoprazan-based regimens for the treatment of H. pylori infection. Phathom in-licensed the U.S., European, and Canadian rights to vonoprazan from Takeda, which completed 19 Phase 3 trials for vonoprazan and received marketing approval in Japan and numerous other countries in Asia and Latin America.
