- Significant Efficacy: In the RESOLVE trial, patients receiving the highest dose (8 mg/site) showed nearly complete normalization of esophageal tissue at 12 weeks, indicating the drug's potential in treating eosinophilic esophagitis (EoE).
- Improved Remission Rates: At 12 weeks (n=19), 58% of patients achieved clinical remission, while 79% maintained remission at 24 weeks (n=14), demonstrating the sustained effectiveness of the treatment.
- Good Safety Profile: To date, over 200 patient-months of follow-up have been reported in 31 patients, with no serious adverse events or cases of oral candidiasis, indicating that EP-104GI is well tolerated at all dose levels.
- Long-term Tracking Data: At 52 weeks (n=6), 67% of patients maintained clinical remission, further validating the drug's long-term efficacy and safety, which may lay the groundwork for future market promotion.

- Clinical Trial Progress: Eupraxia Pharmaceuticals announced positive 12-week and 36-week tissue health data from the Phase 1b/2a RESOLVE trial for EP-104GI, indicating the drug's potential in treating eosinophilic esophagitis (EoE), particularly with the highest dose group showing the greatest improvement from baseline.
- Sustained Efficacy: Patients in the 4mg/site dose group maintained their 12-week improvements at 36 weeks, suggesting that the drug not only effectively manages symptoms but also addresses the underlying pathology of EoE at the tissue level.
