- Vonoprazan is being evaluated in three clinical programs: NERD, erosive esophagitis, and H. pylori infection.

Material changes and development updates
- Phathom expects to initiate a Phase 2 trial in mid-2021 evaluating various vonoprazan doses as an on-demand therapy for NERD.
- The planned NERD program is expected to evaluate both continuous and on-demand dosing regimens.
- Enrollment was completed in November 2020 for PHALCON-EE, a pivotal Phase 3 trial evaluating vonoprazan for healing and maintenance of healing of erosive esophagitis and relief of heartburn.
- Enrollment remained ongoing in PHALCON-HP, a pivotal Phase 3 trial evaluating vonoprazan with antibiotics for eradication of H. pylori infection.

Outlook, risks, and contingencies
The company described the timing of the NERD trial and the PHALCON trial milestones as forward-looking statements, not guarantees. Phathom may delay or cancel the NERD program based on further discussions with the FDA or other considerations.

- Clinical trials may experience additional delays or fail to produce favorable efficacy or safety results.
- The company depends on third parties for manufacturing, research, and preclinical and clinical testing.
- Regulatory developments, adverse effects, inadequate efficacy, product liability, recalls, intellectual-property matters, and compliance with the Takeda license agreement could materially affect development and commercialization.
- COVID-19-related disruptions could affect business operations, clinical trials, manufacturing, and the supply chain.
