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.

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.
