Trial Summary

What is the purpose of this trial?

This trial is testing a medication called povorcitinib to see if it can help people with nonsegmental vitiligo, a condition where skin loses its color in patches. The medication might work by stopping the immune system from attacking the cells that give skin its color. Researchers want to find out if it is effective and safe for these patients.

Will I have to stop taking my current medications?

The trial requires participants to stop using any treatments specifically for vitiligo from the screening through the final safety follow-up visit. It does not specify about other medications, so you may need to discuss this with the trial team.

What data supports the effectiveness of the drug Povorcitinib for treating vitiligo?

Research on similar drugs, like tofacitinib and ruxolitinib, which are also Janus kinase (JAK) inhibitors, shows they can help repigment skin in vitiligo patients. These studies suggest that JAK inhibitors may be effective for vitiligo treatment.12345

How is the drug Povorcitinib different from other vitiligo treatments?

Povorcitinib is a Janus kinase (JAK) inhibitor, similar to other treatments like tofacitinib and ruxolitinib, which have shown effectiveness in treating vitiligo by targeting the immune system to help repigment the skin. What makes Povorcitinib unique is its specific formulation and potential effectiveness, as it is being studied in clinical trials specifically for vitiligo, whereas other JAK inhibitors have been used off-label or in combination with other therapies.12346

Eligibility Criteria

This trial is for adults over 18 with nonsegmental vitiligo, which causes loss of skin color in blotches. Participants should have a certain level of skin involvement and agree to stop other vitiligo treatments during the study. They must also take precautions to prevent pregnancy or avoid fathering children.

Inclusion Criteria

I agree to stop all vitiligo treatments during the study.
Your F-VASI score is at least 0.5 or higher.
More than 5% of your body surface area is affected by the condition being studied.

Findings from Research

Combining low-dose tofacitinib with 308-nm excimer laser treatment shows promise as an effective therapy for patients with nonsegmental vitiligo who have not responded to standard treatments.
This combination therapy could offer a new option for patients struggling with vitiligo, potentially improving their skin condition when other therapies have failed.
Low-dose tofacitinib with 308-nm excimer therapy successfully induced repigmentation in patients with refractory vitiligo.Fang, WC., Lin, SY., Huang, SM., et al.[2022]
Topical tofacitinib, a Janus kinase (JAK) inhibitor, was used in combination with phototherapy for 9 months to treat an adolescent patient with long-standing and treatment-resistant vitiligo.
The treatment resulted in near complete repigmentation of the skin, suggesting that JAK inhibitors may be a promising therapy for vitiligo.

In a phase 2 trial involving patients with vitiligo, those using 1.5% ruxolitinib cream showed a significant improvement in facial Vitiligo Area Scoring Index scores, with a mean improvement of 79.9% at week 24 compared to only 1.1% in those who did not respond.
Proteomic analysis revealed distinct inflammatory biomarker profiles between patients who achieved at least a 50% improvement and those who did not, suggesting that these biomarkers could help identify which patients are more likely to benefit from ruxolitinib treatment.
