Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with physician-confirmed non-segmental vitiligo who meet the trial's minimum face and non-face body surface area and VASI score criteria are ideal candidates.

Probably not a fit

People with segmental or mixed vitiligo, other pigmentary disorders, or who are unable or unwilling to attend study visits and complete procedures are unlikely to benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, randomized, double-blind, placebo-controlled Phase 2b dose-ranging trial that aims to characterize the dose-response of GIA632 in adults with non-segmental vitiligo. Participants are randomized to receive varying doses of GIA632 or placebo during a controlled period to estimate treatment effects versus placebo. The trial then continues into an extension period to assess longer-term safety and efficacy of the selected doses. Study entry requires physician-confirmed non-segmental vitiligo and minimum face and non-face body surface area involvement as measured by VASI scores.

Why it matters

Potential benefit: If successful, GIA632 could help restore pigment in affected skin and identify an effective dose for a larger Phase 3 program.

How similar studies have gone: Other targeted and systemic therapies for vitiligo have shown promise in prior trials, but GIA632's specific clinical benefits and optimal dose are still unproven.
