May-19Undisclosed stageAbingworth; Biotechnology Value Fund; Catalys Pacific; Frazier Healthcare Partners; Greenspring Associates; Janus Henderson Investors; Medicxi; RA Capital Management; Richard King Mellon Foundation; Sahsen Ventures; Takeda Ventures$90M—Phathom Pharmaceuticals was launched on May 15, 2019, through a collaboration between Takeda Pharmaceutical Company and Frazier Healthcare Partners, focusing on the development and commercialization of novel treatments for gastrointestinal diseases and disorders. Takeda granted Phathom a license for vonoprazan, providing exclusive commercialization rights in the United States, Europe, and Canada, in exchange for upfront cash and equity, future milestones, and royalties on net sales. In connection with this license, Phathom completed a $90 million crossover private financing led by Frazier Healthcare Partners, with participation from Medicxi, RA Capital Management, Abingworth, accounts managed by Janus Henderson Investors, BVF Partners LP (Biotechnology Value Fund), Greenspring Associates, Richard King Mellon Foundation, Sahsen Ventures, and undisclosed investors. The company also secured a $50 million term loan facility with Silicon Valley Bank. The financing supported the company's inception and initial operations around the vonoprazan asset, a potassium-competitive acid blocker originally developed by Takeda. Phathom, founded in 2018, aimed to address unmet needs in GI treatments by leveraging vonoprazan's differentiated profile. Phathom later pursued an IPO in 2019, filing to raise up to $100 million and pricing at nearly $182 million.
