Item 8.01 Other Events.
On November 4, 2025, Phathom Pharmaceuticals, Inc. (“Phathom” or the “Company”) announced the first patient has been dosed in its Phase 2 pHalcon EoE-201 clinical trial evaluating VOQUEZNA® (vonoprazan) tablets as an investigational treatment for eosinophilic esophagitis (“EoE”) in adults.
Phathom’s Phase 2 EoE study is a two-part, randomized, double-blind, placebo-controlled study. The first part will enroll 80 adults with endoscopic-confirmed EoE and dysphagia, or trouble swallowing, to be randomized evenly to receive VOQUEZNA 20 mg or placebo, once daily for 12 weeks. Patients who complete the initial 12-week treatment period will be eligible to enter Part 2, a 12-week extension phase, where all subjects will receive VOQUEZNA 20 mg for the remainder of the study.
Topline primary and secondary results are anticipated to be available in 2027.
Forward Looking Statements

All statements other than statements of historical facts contained in this report, including statements regarding: Phathom’s plans, expectations, and goals for development of VOQUEZNA in eosinophilic esophagitis (“EoE”); potential timelines for the pHalcon-EoE-201 study (the “Study”), including timelines for reporting of topline results; the potential for the Study to support discussions on a pediatric program that could extend regulatory exclusivity; the unmet need for additional options in the treatment of EoE and the potential of VOQUEZNA as a treatment option; and Phathom’s plans, expectations and strategies with respect to our business, goals, mission and vision; and as to future performance, results and likelihood of success, are forward-looking statements.

These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including the risk that: Phathom may encounter issues with conduct of the Study that delay its timelines, including slower than expected enrollment or issues with conduct of the study or data analysis; Phathom may receive negative or mixed results from the Study that are not sufficient to advance the program; even if the results of the Study are positive, Phathom may decide not to advance the EoE program and Phathom may decide not to conduct a pediatric program in EoE; if Phathom decides to conduct a pediatric program in EoE, the studies its conduct may not meet the requirements or timelines for receiving an extension of our regulatory exclusivity for VOQUEZNA; the data from the Study or any future studies Phathom may conduct in EoE may not support the potential for VOQUEZNA as a treatment option in this indication; the success of the EoE program may be impacted by potential safety or tolerability issues, competition from other therapies or treatment approaches, or technical issues; future cash needs may cause Phathom to change its plans; and any of the foregoing or other factors may negatively impact our ability to achieve our plans, goals, mission, vision and potential.
