Trevi Therapeutics Announces Positive Outcome of the Sample Size Re-Estimation Analysis in PRISM Trial for Severe Pruritus in Patients With Prurigo Nodularis
Independent Data Monitoring Committee Recommends Continuation of PRISM Trial with Expansion to 360 Subjects per the Adaptive Design
Enrollment Expected to be Complete by Third Quarter 2021
Introducing HADUVIO™ as Proposed
Based on the SSRE analysis the independent Data Monitoring Committee (DMC) recommended that the PRISM trial should continue and that the trial size should increase from an initial enrollment target of 240 to 360 subjects which maintains the statistical power for the primary endpoint. 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.
“Severe pruritus in prurigo nodularis is a very serious and difficult-to-treat condition. We are pleased with the re-estimation results midway through the trial which inform the sample size and further reinforces our view that Haduvio may be an effective treatment option for patients with PN,” said
PRISM Phase 2b/3 Trial Design
The PRISM trial is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of Haduvio for severe pruritus in patients with prurigo nodularis. In this trial, subjects are randomized equally across two treatment groups (Haduvio 162 mg or placebo, twice daily including an initial 2-week blinded titration period). The primary endpoint of the trial is the proportion of patients achieving a greater than or equal to 4-point improvement in the weekly mean Worst Itch Numerical Rating Scale (WI-NRS) score at Week 14, after which all participants rollover to an open-label extension.
