TRVI
September 18, 2025
Trevi Therapeutics announced positive topline results from its Phase 2a RIVER trial of Haduvio for the treatment of patients with refractory chronic cough (RCC). Haduvio met the primary endpoint with a statistically significant reduction in 24-hour cough frequency (p<0.0001). The trial demonstrated a 67% reduction from baseline and a 57% placebo-adjusted reduction in objective 24-hour cough frequency. Similar efficacy was observed in both severe (66% reduction) and moderate (68% reduction) cough subgroups. Haduvio is now the first and only therapy in clinical development to show a statistically significant reduction in chronic cough across both RCC and IPF patients. Patient-reported outcomes also showed statistically significant improvements as early as Day 7, and the safety profile was consistent with previous trials, with no treatment-emergent serious adverse events.
