Moderate-to-Severe Hidradenitis Suppruativa Study (18-100 Years)

A Randomized, Double-blind, Double-dummy, Placebo-controlled, Multicenter, Phase 3 Study Assessing the Efficacy, Safety, and Tolerability of 2 Doses of Remibrutinib Over a 68-week Treatment Period in Adult Patients With Moderate to Severe Hidradenitis Suppurativa

Study Description

The total duration of the study is 76 weeks and consists of: Screening (up to 4 weeks), Treatment Period 1 (16 weeks, double-blind treatment with remibrutinib (Dose A or Dose B) or placebo, Treatment Period 2 (52 weeks, treatment with remibrutinib (Dose A or Dose B) and Safety Follow-Up (treatment-free follow-up for 4 weeks).
Participants who prematurely discontinue study treatment (either during Treatment Period 1 or Treatment Period 2) are encouraged to remain in the study. Participants who do not wish to remain in the study will enter a 4-week Safety Follow-Up period.

 

Brief Summary

The purpose of this study is to establish the efficacy, safety, and tolerability of remibrutinib (LOU064) Dose A and Dose B compared to placebo in participants with moderate to severe hidradenitis suppurativa (HS).
