This is a Phase 3, prospective, randomized, double-blind, placebo-controlled, parallel-group, multicenter clinical trial designed to evaluate the efficacy and safety of N1087 in women with female pattern hair loss (FPHL). Participants will receive either N1087 or placebo for 24 weeks. The study includes a titration period starting at 0.5 mg and increasing up to 2 mg daily, followed by treatment at the maximum tolerated dose. The primary objective is to assess changes in non-vellus hair density in the target scalp area after 24 weeks. Secondary objectives include changes in terminal hair density, hair thickness, global photographic assessment, quality of life, and participant satisfaction. Safety will be monitored through adverse events, vital signs, and laboratory tests. Approximately 372 participants will be randomized in a 2:1 ratio (N1087 vs. placebo) across about 10 research centers in Brazil.
Female participants aged ≥18 years and ≤60 years at the time of signing the informed consent form.
Presentation of female pattern hair loss in stages 2 to 4 of the Sinclair scale (Women's Alopecia Severity Scale - WASS), based on the Investigator's clinical examination.
Absence of specific treatment for female pattern hair loss (FPHL) in the last 6 months or history of specific treatment for FPHL lasting ≤30 days in the last 6 months. Participants currently using specific treatment for FPHL or with prior use lasting >30 days in the last 6 months must complete a 3-month washout period before the Randomization Visit (RV).
Willing to agree to all procedures and assessments required by the clinical trial, including a permanent tattoo applied to the scalp and shaving of the target area.
Participant presenting other causes of alopecia, such as: alopecia areata, scarring alopecia, traction alopecia, nutritional deficiency, monilethrix, trichotillomania, trichothiodystrophy, chemotherapy-induced alopecia.
Participant who experienced telogen effluvium in the last 6 months, such as after childbirth, infection, intense stress.
Participant presenting other dermatological conditions on the scalp, such as: seborrheic dermatitis, psoriasis, eczema, scalp mycosis.
Participant presenting signs or symptoms of hyperandrogenism, such as: hirsutism, moderate to severe acne.
