ClinConnect Summary

This clinical trial is studying a new treatment called SAR444656 for adults with moderate to severe Hidradenitis Suppurativa (HS), a painful skin condition. The trial aims to find out if this treatment is effective and safe compared to a placebo, which is an inactive substance. To participate, individuals must be between 18 and 70 years old and have had HS symptoms for at least a year. They should also have HS lesions in at least two different areas of their body, with one area showing more severe symptoms. Participants need to have tried oral antibiotics for at least one month without much improvement.

If eligible, participants can expect to be involved in the study for about 24 weeks, which includes a screening period, 16 weeks of treatment, and a follow-up period. Throughout the study, they will have around 14 visits to the clinic, where they will receive the treatment and monitor their progress. It's important for participants to be willing to keep a daily diary about their condition during the study. Overall, the trial is looking for ways to help manage HS better and improve the quality of life for those affected by this challenging condition.

• • Participant must have had an inadequate response after at least one-month of oral antibiotic treatment for HS, as assessed by the Investigator.
• • Participant must have a total AN count of ≥5 at the baseline visit.
• • Participant must have a draining tunnel count of ≤20 at the baseline visit.
• • Participant must be willing and able to complete the diary for the duration of the study as required by the study protocol.
• • Contraceptive use by men with a partner of childbearing potential and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
• Exclusion Criteria:
• • Participant with any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with assessment of HS.
• • Any active or chronic infection requiring systemic treatment (eg, antibiotics, antivirals, antifungals, antihelminthics) within 30 days prior to baseline.
• • Known history of or suspected significant suppressed immune response, including history of invasive opportunistic or helminthic infections despite infection resolution or otherwise recurrent infections of abnormal frequency or prolonged duration.
• • Participant with history of solid organ transplant.
• • Participant with history of splenectomy.
• • Participant with history of any malignancy or lymphoproliferative disease, except if the participant has been free from disease for ≥5 years. Successfully treated non-metastatic cutaneous squamous cell carcinoma, basal cell carcinoma, or localized carcinoma in situ of the cervix are allowed.

• • Participant with family history of sudden death or long QT syndrome.
• • Participant with history of congenital or drug-induced long QT syndrome.
• • Participant with congestive heart failure (New York Heart Association Class 2 to 4), greater than Class 1 angina pectoris, acute coronary syndrome within prior 6 months, known structural heart disease.
• • Participant with history of any major cardiovascular events (eg, myocardial infarction, unstable angina pectoris, coronary revascularization, stroke, or transient ischemic attack) at any time prior to screening.
• • Participant with history of ventricular fibrillation, ventricular tachycardia, torsades de pointes, atrial fibrillation, syncope not explained by non-cardiac etiology.
• • Participant with uncontrolled hypertension defined as consistent systolic blood pressure ≥150 mmHg or consistent diastolic blood pressure ≥90 mmHg despite antihypertensive medication.
• • Participant received prescription topical therapies for the treatment of HS within 14 days prior to the baseline visit.
• * Prior or active treatment with any systemic biologic (anti-TNF) therapy, anti-IL17 therapy, anti-IL1/anti-IL1 receptor therapy except for up to 20% of the total study population. Furthermore, this 20% of biologic-experienced participants must fulfilled one or more of the following conditions:
• • Discontinued due to treatment related toxicity and/or
• • Discontinuation is not related to lack or loss of therapeutic response.
• • The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
