About Vonoprazan

Vonoprazan, is an 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 rapid, potent and durable anti-secretory effects and has demonstrated clinical benefits over standard of care treatments 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 U.S. Food and Drug Administration (FDA) has designated vonoprazan as a qualified infectious disease product (QIDP) and awarded Fast Track status for the treatment of H. pylori infection in combination with both amoxicillin and clarithromycin and with amoxicillin alone. Phathom in-licensed the U.S., European and Canadian rights to vonoprazan from Takeda, which completed 17 Phase 3 trials for vonoprazan and received marketing approval in Japan and numerous other countries in Asia and Latin America.
