EP-104GI's Phase 2b RESOLVE readout will test whether local corticosteroid delivery can durably control EoE without the systemic risks of biologics

EP-104GI is a locally-delivered, extended-release fluticasone propionate formulation targeting adults with eosinophilic esophagitis who require sustained disease control. The thesis resolves on Phase 2b RESOLVE topline data in Q4 2026 showing histological remission at rates meaningfully superior to placebo at the 120mg or 160mg dose. The primary competitive risk is dupilumab (Dupixent), already approved for EoE with a large real-world prescriber base, which sets a high clinical and commercial bar for any new entrant.

Focus

EP-104GI Phase 2b RESOLVE topline data

Q4 2026

Bull

A positive outcome would show statistically significant histological remission (peak eosinophil count ≤15 eos/hpf) and sustained symptom response (SDI reduction ≥3 points) at the primary endpoint timepoint across the 120mg and/or 160mg dose arms, consistent with Phase 1b/2a signals. This would confirm dose-response durability, validate the delivery platform, and position EP-104GI as a steroid-based alternative to biologics — potentially enabling a pivotal Phase 3 design and attracting partnership interest from gastroenterology-focused acquirers.

Bear

The most likely failure modes are insufficient histological response rate at the higher doses in the expanded Phase 2b population, loss of the dose-response signal seen in the small Phase 1b/2a cohorts, or meaningful procedural variability in esophageal drug coverage that dilutes efficacy in intent-to-treat analysis. A secondary concern is that durability beyond 36 weeks — the key differentiation claim versus swallowed topical corticosteroids — may not be adequately demonstrated within the trial's readout window, undermining the 'durable control' pillar of the thesis.
