Summary
Povorcitinib has reached Phase III as its most advanced recorded development stage across any indication, and the database holds no approval for Vitiligo. ClinicalTrials.gov lists 3 registered trials linking Povorcitinib to Vitiligo: 2 are active or not yet recruiting; 1 has completed. The most advanced is Phase 3 (NCT06113445). It plans or enrolled 467 participants. Registration activity spans 2021 to 2023. The literature layer holds 2 publications for this pair: 1 Cochrane review and 1 clinical trial publication. Publication years run from 2025 to 2026. Because at least one synthesis-level source exists (systematic review, meta-analysis or Cochrane review), this pair has been assessed beyond single studies, although the synthesis may concern a different indication.
The RepurpOS disease-intelligence file for Vitiligo ranks 50 candidate therapeutics from Open Targets, ChEMBL, DGIdb and PubMed; only a minority carry direct clinical evidence, and this page covers one of those. Spontaneous remission context recorded for the condition: Spontaneous complete repigmentation extremely rare (<1%); partial spontaneous repigmentation possible in small lesions; progressive without treatment in most patients.

How the evidence score is calculated
- Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
- Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
- The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
- Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
- The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.

Mechanism and notes
No mechanism of action is recorded for this pair in the source databases.
OSMF's existing evidence tier for this pair is B (Moderate), derived from the strength of the disease association recorded in Open Targets. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Povorcitinib approved for Vitiligo?
Povorcitinib has reached Phase III as its most advanced recorded development stage across any indication, and the database holds no approval for Vitiligo. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Povorcitinib in clinical trials for Vitiligo?
ClinicalTrials.gov lists 3 registered trials linking Povorcitinib to Vitiligo: 2 are active or not yet recruiting; 1 has completed. The most advanced is Phase 3 (NCT06113445). It plans or enrolled 467 participants. Registration activity spans 2021 to 2023.
What does the evidence show for Povorcitinib in Vitiligo?
Povorcitinib has both completed registered trials and synthesis-level publications linked to Vitiligo. That is the strongest profile in this database, but the summaries here do not extract effect sizes, so read the linked reviews for direction and magnitude of benefit. OSMF's existing evidence tier for this pair is B (Moderate), derived from the strength of the disease association recorded in Open Targets. The tier describes how well the drug-disease link is documented, not how well the drug works.
