Phathom Pharmaceuticals is a commercial-stage biopharma company focused on gastrointestinal diseases, built around vonoprazan, a potassium-competitive acid blocker marketed in the U.S. as VOQUEZNA, VOQUEZNA DUAL PAK and VOQUEZNA TRIPLE PAK.
The products treat erosive and non-erosive GERD and Helicobacter pylori infection, with U.S. launches beginning in late 2023. The company reports higher 2025 revenues from VOQUEZNA products versus the prior year, driven by growing prescription volume and prescriber adoption, with most use in GERD. As of February 13, 2026, more than 1.1 million prescriptions have been filled and VOQUEZNA has commercial coverage for over 120 million, or more than 80%, of U.S. commercial lives.
Regulatory protection is a major asset: QIDP and new chemical entity status, plus an FDA-granted citizen petition, give all three VOQUEZNA products U.S. exclusivity through May 3, 2032. Phathom is also advancing a Phase 2 trial of vonoprazan in eosinophilic esophagitis and evaluating additional lifecycle, geographic and OTC opportunities, while facing competition from generic PPIs and emerging PCABs.
Phathom Pharmaceuticals reported strong revenue growth but continued losses for the fourth quarter and full year 2025. Net product revenue reached $57.6 million in the fourth quarter, up from $29.7 million a year earlier, and $175.1 million for 2025 versus $55.3 million in 2024.
Full-year operating expenses fell to $312.5 million from $324.7 million, and the GAAP net loss narrowed to $221.2 million from $334.3 million. Cash and cash equivalents were $130.0 million at December 31, 2025, compared with $297.3 million a year earlier, while total liabilities increased and stockholders’ deficit deepened.
Management highlighted VOQUEZNA commercial momentum, a sales force realignment, and a January financing followed by a term loan modification to reduce interest and extend maturity. The company stated that it is positioning for anticipated operating profitability in the third quarter 2026 and to reach cash flow positivity in 2027, supported by tighter expense discipline and revenue growth.
