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. ^{1 2 3 4 5}

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. ^{1 2 3 4 6}

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.

Participants will receive Povorcitinib Dose A for 52 weeks, followed by Povorcitinib Dose A for 52 weeks.

Group II: Placebo Placebo Group 1 Intervention

Participants will receive Placebo for 52 weeks, followed by Povorcitinib Dose A for 52 weeks.

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.

Topical Tofacitinib: A Janus Kinase Inhibitor for the Treatment of Vitiligo in an Adolescent Patient. Berbert Ferreira, S., Berbert Ferreira, R., Neves Neto, AC., et al.[2021]

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.

Baseline Levels of Circulating Inflammatory Biomarkers Stratify Patients with Vitiligo Who Significantly Repigment after Treatment with Ruxolitinib Cream. Howell, MD., Kuo, FI., Rumberger, B., et al.[2023]

In two 52-week phase 3 trials, 52% of patients treated with ruxolitinib 1.5% cream experienced at least a 75% improvement in their vitiligo, demonstrating its efficacy as a treatment.

Ruxolitinib is the first FDA-approved topical medication for repigmentation in vitiligo patients, showing it is both safe and effective, although its cost may limit accessibility for some patients.

The combination of apremilast and narrowband UVB therapy significantly reduces immune cell markers (like CD8+ T cells) and enhances melanogenesis markers in vitiligo skin, suggesting a more effective treatment approach than narrowband UVB alone.

This study supports the clinical observation that apremilast can enhance the repigmentation effects of narrowband UVB therapy in patients with generalized vitiligo, particularly in skin types IV-VI, although it was limited by a small sample size and high dropout rate.

Apremilast and narrowband ultraviolet B combination therapy suppresses Th17 axis and promotes melanogenesis in vitiligo skin: a randomized, split-body, pilot study in skin types IV-VI. Kim, HJ., Del Duca, E., Pavel, AB., et al.[2023]

Topical ruxolitinib cream has been shown to significantly improve vitiligo symptoms, with 58% of patients achieving a 50% improvement in Vitiligo Area Scoring Index (VASI) after 52 weeks of treatment, making it an effective option for repigmentation.

The treatment has a favorable safety profile, with only mild adverse effects reported, such as erythema and pruritus, and it offers significant clinical improvements compared to traditional therapies, which may have more severe side effects.
