This is a multinational, randomized, double-blind, placebo-controlled, Phase 2, dose finding study to evaluate the efficacy and safety of different doses of SAR445399 in adult participants with moderate to severe hidradenitis suppurativa.
The purpose of this study is to assess the efficacy and safety of two doses of SAR445399 compared with placebo in adult participants with moderate to severe hidradenitis suppurativa.
The study duration (per participant) will be up to 46 weeks with a total of 16 visits. The treatment duration will be 32 weeks which includes 16-week double-blinded initial treatment period and a 16-week treatment-blinded extension period.
Participants with a history of signs and symptoms consistent with hidradenitis suppurativa (HS) for at least 6 months prior to Baseline
Participants must have HS lesions present in at least 2 distinct anatomic areas (eg, left, and right axilla; or left axilla and left inguino-crural fold), with at least 1 body site being Hurley Stage II or III.
Participant must have a total abscess and inflammatory nodule (AN) count of ≥5 at the Baseline Visit.
Participant must have had an inadequate response to a trial of an oral antibiotic for treatment of HS, exhibited recurrence after discontinuation of antibiotics or demonstrated intolerance to antibiotics or has a contraindication to oral antibiotics for treatment of their HS as assessed by the Investigator through participant interview and review of medical history.
Any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with assessment of HS.
History of recurrent or recent serious infection
Known history of or suspected current immunosuppression
History of solid organ transplant or stem cell transplant.
