Item 8.01 Other Events.
On July 13, 2020, Trevi Therapeutics, Inc. (the “Company”) announced the completion of the pre-specified sample size re-estimation (the “SSRE”) analysis for its ongoing PRISM Phase 2b/3 trial of Haduvio™ (nalbuphine ER) for severe pruritus in patients with prurigo nodularis.
Based on the SSRE analysis, the independent Data Monitoring Committee (the “DMC”) recommended that the trial size should be increased from an initial enrollment target of 240 to 360 subjects, which maintains the statistical power for the primary endpoint of the trial. The DMC’s recommendation was based on a pre-specified interim conditional power assessment conducted after approximately 45% of the initial targeted number of patients were evaluable for the primary endpoint of the trial. Based on the DMC’s recommendation, the Company plans to increase the size of the trial to 360 subjects.
The Company has increased the number of active sites in the PRISM trial to more than 60 sites globally, and approximately 140 subjects have enrolled in the study. Based on the increased size of the trial and considering COVID-19 related restrictions, the Company expects to complete enrollment in the third quarter of 2021 and report top-line data in the fourth quarter of 2021.
The Company intends to propose Haduvio as the trade name for the nalbuphine ER investigational product and will therefore use that name in its materials going forward. Haduvio is an investigational drug product and its safety and efficacy have not been fully evaluated by any regulatory authority.
