A Single-center, Prospective, Self-controlled, Observational Real-world Study of the Efficacy and Safety of Anti-IL-17A/F Monoclonal Antibody Combined With Non-ablative Dot Laser for the Treatment of Mild to Moderate Hidradenitis Suppurativa

Starting soon · Phase 4

Conditions studied: Hidradenitis Suppurativa (HS)

In brief

The goal of this clinical trial is to learn if combining an IL-17A/F monoclonal antibody with non-ablative fractional laser therapy works and is safe in patients with mild to moderate hidradenitis suppurativa (HS). The main questions it aims to answer are: Does the combination treatment reduce HS symptoms compared to before treatment? What are the main side effects of this combination treatment? Researchers will compare how participants feel and look after treatment to their own condition before treatment. Participants will: Get the combined treatment once every 4 weeks for 16 weeks Give skin and blood samples before the first treatment and at the last treatment visit Have a final check-up 8 weeks after the last treatment
