First-line treatment for vulvar lichen sclerosus consists of high-potency topical corticosteroids. Although many patients experience symptom relief, a considerable number of women continue to have persistent symptoms or progressive anatomical damage. For these patients, therapeutic options are limited. MTX is an immunomodulatory medication that has been used for several decades in the treatment of inflammatory and autoimmune diseases. Previous clinical observations suggest that MTX may be beneficial for patients with severe or treatment-resistant vulvar lichen sclerosus; however, prospective clinical studies in this population remain scarce. This prospective, open-label, phase II pilot study aims to evaluate the efficacy and safety of subcutaneous injectable MTX, administered once weekly at a standardized initial dose of 12.5 mg, in women with severe vulvar lichen sclerosus who have not responded adequately to standard topical therapy.
