- Clinical Trial Results: Trevi Therapeutics published Phase 2b CORAL trial results in JAMA, showing statistically significant reductions in 24-hour objective cough frequency across all nalbuphine ER dose groups at Week 6, indicating the drug's potential for treating chronic cough in patients with idiopathic pulmonary fibrosis (IPF).
- Patient Response Consistency: Over 60% of patients treated with nalbuphine ER achieved at least a 50% reduction in 24-hour cough frequency by Week 6, with patient-reported outcomes aligning with objective monitoring results, underscoring the drug's clinical value and overall patient improvement.
- Safety Analysis: The safety profile from the CORAL trial was consistent with previous studies, showing a 5.6% discontinuation rate due to adverse events in the nalbuphine ER group, comparable to 5.0% in the placebo group, indicating good safety for further development.
- Market Demand: With approximately 150,000 patients suffering from IPF in the U.S., two-thirds of whom experience uncontrolled chronic cough, the development of nalbuphine ER addresses this significant unmet medical need and has the potential to enhance patient quality of life while reducing morbidity and mortality risks.
