About Us

Leading the way to a potential new standard of care for gastrointestinal diseases

Phathom Pharmaceuticals is a late clinical-stage biopharmaceutical company focused on developing and commercializing new treatments for GI diseases. We have licensed the exclusive rights in the United States, Europe, and Canada to vonoprazan, a potassium competitive acid blocker (P-CAB) in late clinical-stage development for the treatment of gastric acid-related diseases. We have initiated Phase 3 clinical trials for the treatment of erosive GERD and the treatment of H. pylori infection. Vonoprazan has the potential to be the first gastric anti-secretory agent from a new class approved in the United States, Europe, or Canada in over 30 years.

Phathom has assembled a team of seasoned gastrointestinal and pharmaceutical industry experts with deep expertise in developing GI therapeutics, including anti-secretory agents.
