Two Trials to Evaluate TEV-53408 in Participants With Non-Segmental Vitiligo

30 de octubre de 2026 actualizado por: Teva Branded Pharmaceutical Products R&D LLC

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Program Consisting of a Phase 2b Trial and a Phase 3 Trial to Evaluate the Efficacy and Safety of TEV-53408 in Participants With Non-Segmental Vitiligo

The goal of these clinical trials is to learn if TEV-53408 can help adults with Non-Segmental Vitiligo (NSV). Vitiligo causes patches of skin to lose their color.

The main questions the trials aim to answer are:

Can TEV-53408 help bring color back to the skin on the face? Can TEV-53408 help bring color back to the skin on the body? What side effects may happen with TEV-53408?

TEV-53408 will be compared with placebo to see if it helps bring color back to the skin.

Participants will:

Receive TEV-53408 or placebo as an injection under the skin Have their skin checked during the trials Answer questions about how vitiligo affects their daily life Have blood tests and other health checks

Inclusion Criteria:

  • The participant must have a diagnosis of Non-Segmental Vitiligo (NSV) for at least 3 months prior to screening. Participants of all skin types, as assessed by the Fitzpatrick scale, may be included.
  • Stable or active NSV for at least 3 months prior to screening and the VASI scores: The participant has an F-VASI score ≥0.5 and a T-VASI score ≥5 and ≤60.
  • A female participant is not pregnant or breastfeeding and agrees to refrain from donating oocytes throughout the duration of the trial.
  • A male participant agrees to Refrain from donating sperm, EITHER abstains from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agrees to remain abstinent OR agrees to use a male condom with female partner.

NOTE- Additional criteria may apply at screening for clinical trial participation.

Exclusion Criteria:

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Trial 1: Proportion of Participants Achieving a ≥75% Reduction in Facial Vitiligo Area Scoring Index (F-VASI75)
Periodo de tiempo: Baseline, Week 24

The F-VASI assesses the percentage of facial area affected by vitiligo. It ranges from 0 to 3.5, with 0 representing no vitiligo on the face and 3.5 representing complete depigmentation of the assessed facial areas.

Baseline, Week 24
Trial 2: Proportion of Participants Achieving F-VASI75
Periodo de tiempo: Baseline, Week 48
Baseline, Week 48
Trial 2: Proportion of Participants Achieving T-VASI50 (US Only)
Periodo de tiempo: Baseline, Week 48

T-VASI is the sum for all body sites of the product of percentage of BSA affected multiplied by the degree of depigmentation. T-VASI ranges from 0 to 100, with 0 representing no vitiligo and 100 representing complete depigmentation of the entire body.

Baseline, Week 48
