Tirzepatide for Treatment of CCCA

2. november 2026 opdateret af: Johns Hopkins University

The goal of this pilot clinical trial is to learn if tirzepatide can treat active central centrifugal cicatricial alopecia (CCCA), a type of permanent scarring hair loss, in adults. The main questions it aims to answer are:

  • Does tirzepatide improve the symptoms and signs of active CCCA?
  • Does tirzepatide change the activity of genes in the scalp, especially genes related to scarring?
  • Does tirzepatide promote hair regrowth?

Participants will:

  • Inject tirzepatide once a week for 12 months.
  • Visit the clinic for scalp examinations, photographs, and other health assessments.
  • Have scalp biopsies at the beginning of the study and after 6 months of treatment.
  • Have blood tests and other safety monitoring during the study.

There is no separate comparison group. Researchers will compare each participant's results during treatment with the participant's results at the beginning of the study.

Intervention / Behandling
Eksperimentel: Tirzepatide Treatment

Participants will self-administer tirzepatide by subcutaneous injection once weekly for 12 months. Tirzepatide will be administered at 2.5 mg once weekly for the first 4 weeks, followed by 5 mg once weekly for the remainder of the study. Participants may use topical corticosteroids as needed for intolerable CCCA-related symptoms, such as scalp pain or itching.

Tirzepatide solution will be self-administered by subcutaneous injection once weekly. Participants will receive 2.5 mg once weekly for the first 4 weeks, followed by 5 mg once weekly for the remainder of the 12-month treatment period. Injection sites will be rotated among the abdomen, thigh, or upper arm.

Foranstaltningsbeskrivelse
Tidsramme
Change in Central Centrifugal Cicatricial Alopecia Clinical Activity Tool Score
Tidsramme: Baseline, 3 months, 6 months

Disease activity will be measured using the Central Centrifugal Cicatricial Alopecia Clinical Activity Tool (C-CAT). The C-CAT assesses disease progression, scalp pain or tenderness, scalp itching, inflammation, and scalp fibrosis. Total scores range from 0 to 10, with higher scores indicating greater disease activity. Scores obtained during treatment will be compared with the baseline score.

Baseline, 3 months, 6 months
Change in Scalp Gene-Expression Profiles
Tidsramme: Baseline, 6 months

Differential messenger RNA expression will be assessed using bulk RNA sequencing of paired scalp biopsies collected at baseline and 6 months of tirzepatide treatment. Differential expression will be defined as at least a two-fold change with an adjusted p-value less than 0.05. Analyses will focus on profibrotic and inflammatory pathways, including transforming growth factor beta, collagens 1, 3, and 6A1, and T-helper 17-related pathways.

Foranstaltningsbeskrivelse
Tidsramme
Change in Central Hair Loss Grade
Tidsramme: Baseline, 3 months, 6 months

Central scalp hair loss will be evaluated by physician raters using standardized clinical photographs and the Central Hair Loss Grade scale. Scores range from 0 to 5, with higher scores indicating more severe central hair loss. Scores obtained during treatment will be compared with the baseline score.

Baseline, 3 months, 6 months
Physician Global Assessment of Change in Hair Loss
Tidsramme: Baseline, 3 months, 6 months

Physician raters will compare standardized clinical photographs obtained at months 3 and 6 with baseline photographs. Change in hair loss will be evaluated using a 5-point physician global assessment scale. Score range 0 (None) - 4 (Very severe).
