Nemolizumab to Treat Lichen Planopilaris, a Noncontrolled, Prospective, Pilot Study.

brief summary

Lichen planopilaris (LPP) is a primary lymphocytic cicatricial alopecia characterized by progressive, permanent hair loss and scalp symptoms such as pruritus and burning. Current treatments-including topical and intralesional corticosteroids, hydroxychloroquine, and immunosuppressants-are often inadequate, with limited evidence for efficacy and frequent treatment switching or discontinuation due to side effects or lack of response.1,2 Recent systematic reviews and meta-analyses highlight the need for new, targeted therapies. 3,4 Nemolizumab, an IL-31 receptor antagonist, FDA-approved for prurigo nodularis and atopic dermatitis, has demonstrated efficacy in pruritic and fibrosing dermatoses, making it a rational candidate for LPP.
