Detailed Narrative
Clinical Trial Progress and Enrollment
Trevi Therapeutics initiated both the OCEAN-1 Phase III 52-week trial for IPF-related chronic cough and the LAKE Phase IIb trial for refractory chronic cough (RCC) during Q2 FY26. The company also plans to initiate the OCEAN-2 Phase III 12-week trial for IPF-related chronic cough in Q3 FY26. Global site activation is underway for these trials, totaling over 200 sites, with early enrollment on track. A milestone disclosure will occur once approximately 50% enrollment is reached in any trial.
Non-IPF-ILD Chronic Cough Program
The company submitted a meeting request to the FDA to discuss its non-IPF-ILD-related chronic cough program, expecting a response this month. If granted, a full protocol and briefing document will be submitted for discussion on the next trial and development plan. Management notes significant synergies with IPF studies, as these patient populations are seen in the same care centers by the same pulmonologists, allowing for efficient trial setup.
LAKE Trial SSRE and RCC Market Landscape
The Sample Size Reestimation (SSRE) for the LAKE trial in RCC is expected to read out in Q4 FY26. This SSRE is designed to confirm powering assumptions and adjust the sample size if needed, based on an analysis by an external unblinded statistician. Management emphasized that the recent termination of a competitive RCC program does not impact their trial design, which is powered by their own data and strong effect size observed in previous studies. The company maintains its strategy to target treatment-resistant RCC patients, a sizable market opportunity.
ATS 2026 Highlights and Awareness Campaign
At the American Thoracic Society (ATS) 2026 meeting, all six of Trevi's submissions were selected for presentations or posters. These included new data on nalbuphine ER's reduction of breathlessness and cough bouts in IPF and RCC patients, and its robust response across all baseline cough counts. The Phase IIb CORAL trial for IPF-related chronic cough was also highlighted in the Clinical Year in Review session. Additionally, an unbranded digital campaign raising awareness of chronic cough among pulmonologists reached over 17,000 unique pulmonologists, demonstrating strong engagement.
Financial Position and Cash Runway
Trevi Therapeutics ended Q2 FY26 with approximately $319 million in cash, cash equivalents, and marketable securities. The company remains on track with its budget and plans, and its cash runway guidance extends into 2030. This funding is expected to cover the development program for IPF-related chronic cough through potential FDA approval, the clinical development program through Phase III for non-IPF-ILD-related chronic cough, and the ongoing Phase IIb LAKE trial for RCC, including pre-commercial activities. It does not include expenses for commercial launch or a Phase III RCC trial.
Intellectual Property Expansion
The company is actively expanding its intellectual property portfolio, with several incremental patent applications filed in recent months. While no new issuances have been disclosed since the last quarter, the ongoing effort aims to strengthen the company's position and protect its programs.
