NEW HAVEN, Conn., Oct. 21, 2024 - Trevi Therapeutics, Inc. (Nasdaq: TRVI), a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine ER) for the treatment of chronic cough in idiopathic pulmonary fibrosis (IPF) and refractory chronic cough (RCC), today announced that it has completed enrollment in its Phase 2a trial for the treatment of RCC ("RIVER") and expects to report topline data in the first quarter of 2025.
"We are happy to have completed enrollment for our Phase 2a RIVER trial for the treatment of RCC," said Jennifer Good, President and CEO of Trevi Therapeutics. "RCC impacts approximately 2-3 million adults in the U.S. and with no approved treatment options, there is a large unmet need for new therapies that address cough hypersensitivity. We look forward to reporting the topline results for RIVER early next year and building on the positive results we have seen in studying chronic cough in IPF."
Phase 2a Trial Design: Refractory Chronic Cough Improvement Via Nal ER (RIVER)
The Phase 2a RIVER trial is a randomized, double-blind, placebo-controlled, two-treatment, two-period, crossover study designed to evaluate the efficacy, safety, tolerability and dosing of Haduvio for the treatment of RCC. The trial is being conducted at multiple sites in the United Kingdom and Canada. The primary endpoint of the trial is a mean change in 24-hour cough frequency in the overall population as determined using an objective cough monitor. Based on the screening results, the study will enroll patients into one of two subgroups: 10-19 coughs/hour (moderate 24-hour cough frequency) and ≥20 coughs/hour (high 24-hour cough frequency). The trial will also explore secondary endpoints, including patient-reported outcome measures for cough frequency and severity. The trial was designed to enroll approximately 60 adult patients.
About Refractory Chronic Cough (RCC)
Refractory chronic cough has no approved therapies in the U.S. and is defined as a persistent cough lasting >8 weeks despite treatment for an underlying condition (i.e., asthma, gastroesophageal reflux disease, non-asthmatic eosinophilic bronchitis, and upper airway cough syndrome or post-nasal drip) or where no underlying condition exists. RCC affects ~2-3 million patients in the U.S. and is caused by cough reflex hypersensitivity in both the central and peripheral nerves. It is highly disruptive and accompanied by a wide range of complications, ranging from urinary incontinence in females to sleep disruption and social embarrassment that causes significant social and economic burdens for patients and those around them.
About Trevi Therapeutics, Inc.
Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ (oral nalbuphine extended-release (ER)) for the treatment of chronic cough in idiopathic pulmonary fibrosis (IPF) and refractory chronic cough (RCC). Haduvio acts on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist (KAMA), which are opioid receptors that play a key role in controlling cough hypersensitivity. Nalbuphine is not scheduled by the U.S. Drug Enforcement Agency.
The impact of chronic cough is significant and often leads to a decline in patients' social, physical, and psychological quality of life. In IPF, chronic cough may lead to worsening disease and may be associated with a higher risk of progression, death, or need for lung transplant. There are no approved therapies for the treatment of chronic cough in IPF and current treatment options provide minimal benefit to patients. Chronic cough affects up to 10% of the adult population, and Haduvio's expansion into RCC has the potential to reach patients suffering from moderate to severe refractory chronic cough. There are also no approved therapies for RCC in the U.S.
Trevi intends to propose Haduvio as the trade name for oral nalbuphine ER. Its safety and efficacy have not been evaluated by any regulatory authority.
