Is this trial a fit for you?
✓Likely a good fit
Adults with a confirmed IPF diagnosis, chronic cough for 8 weeks or more, and adequate lung function who may be on a stable antifibrotic regimen.
✕Probably not a fit
Patients with recent respiratory infections, recent respiratory hospitalizations, or insufficient lung function may not benefit from this treatment.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This randomized, double-blind study compares nalbuphine extended-release tablets to placebo in adults with IPF and persistent cough. Eligible participants have documented IPF, a chronic cough for at least 8 weeks, and specific lung function criteria, and must be on a stable antifibrotic regimen if applicable. The trial aims to assess safety and efficacy over a defined treatment period. Sites are located in California, with Trevi Therapeutics as the lead sponsor. Exclusion criteria include recent respiratory infections or hospitalization for respiratory illness.
Why it matters
Potential benefit: If successful, participants may experience a reduction in IPF-related chronic cough and improved quality of life.
How similar studies have gone: Prior approaches to treating cough in IPF have yielded mixed results, making this targeted nalbuphine approach relatively novel in this population.

Inclusion Criteria: * Diagnosis of IPF as determined by the Investigator based on American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Society (ALAT) clinical practice guidelines. * Chronic cough for ≥8 weeks prior to Screening. * PGI-Severity Score ≥ 2 at Screening. * Forced vital capacity (FVC) ≥40 percent (%) of predicted at Screening. * Diffusing capacity for carbon monoxide (DLCO) ≥25% of predicted during Screening or within 12 weeks prior to Screening. * Participants who are currently taking antifibrotic medication (nintedanib, pirfenidone, nerandomilast) approved for IPF should be on a stable dose for at least 6 weeks prior to the Baseline Visit. Exclusion Criteria: * Clinical diagnosis or clinical suspicion of an upper or lower respiratory tract infection in the last 8 weeks prior to the Screening visit or during Screening. * Hospitalization for any respiratory illness (including acute exacerbation of IPF) within 2 months prior to Screening. Note: Other protocol-defined inclusion/exclusion criteria may apply.
