Trevi Therapeutics Develops Novel Treatment for Chronic Cough
Trevi Therapeutics, Inc. (NASDAQ: TRVI) is making strides in the fight against chronic cough associated with idiopathic pulmonary fibrosis (IPF). This clinical-stage biopharmaceutical company recently completed enrollment in its Phase 2b CORAL trial, which investigates the effectiveness of Haduvio™, an oral extended-release formulation of nalbuphine. Expectations are set high with topline results anticipated to arrive in the first half of 2025.
Understanding the CORAL Trial
The CORAL trial is designed to assess Haduvio's efficacy against chronic cough, a common yet debilitating symptom in IPF patients, with a significant sample size of approximately 160 individuals involved. The trial utilizes a double-blind, randomized, placebo-controlled approach over a span of six weeks, with three varying doses of Haduvio - 27mg, 54mg, and 108mg - compared directly against a placebo.
Research Goals and Endpoint Measurements
Leveraging a patient-focused design, the primary efficacy endpoint measures the relative change in 24-hour cough frequency by using an objective cough monitor at the end of Week 6, comparing Haduvio’s impact to that of the placebo. This analytic method is crucial due to the chronic nature of cough experienced by IPF patients, which often complicates their overall health condition.
The Challenge of Chronic Cough in IPF Patients
Chronic cough in patients with IPF is a significant concern, affecting up to 85% of this population. With around 140,000 individuals diagnosed with IPF in the United States, the persistent coughing can occur as often as 1,500 times daily, leading to increased health risks, including lung transplant needs. Current treatments have proven largely ineffective, highlighting the urgent need for innovative solutions.
Impact on Quality of Life
The implications of chronic cough go beyond physical health, severely impacting the social, emotional, and psychological well-being of patients. Many individuals report feelings of embarrassment, social withdrawal, and disturbances in their daily lives, underlining the importance of successful treatment options.
Haduvio's Mechanism of Action
Haduvio acts on both central and peripheral opioid receptors by functioning as a kappa agonist and mu antagonist (KAMA). This dual action may provide a comprehensive approach to control cough symptoms, aiming to alleviate the persistent discomfort experienced by those with chronic cough and IPF.
Significance of the Upcoming Results
The data gathered from the CORAL trial will be pivotal in shaping Trevi's subsequent steps in the development of Haduvio. The findings will inform optimal dosing strategies to advance into pivotal Phase 3 clinical trials, alongside fulfilling the critical needs of patients suffering from chronic cough.
