Frequently Asked Questions about OPZELURA
About OPZELURA
OPZELURA is a topical JAK inhibitor indicated for the treatment of nonsegmental vitiligo. It is applied to affected skin to help support repigmentation by targeting pathways involved in depigmentation.1,2
OPZELURA is indicated for use in adults and children 12 years of age and older with nonsegmental vitiligo. It helps support repigmentation of affected skin areas in patients.1
Treatment options for nonsegmental vitiligo include topicals and phototherapy aimed at helping repigmentation. OPZELURA is a non-steroidal topical option that targets underlying pathways involved in depigmentation.1,3
Mechanism of Action
OPZELURA works by inhibiting Janus kinase (JAK1 and JAK2), which are involved in immune signaling associated with nonsegmental vitiligo. By blocking JAK-STAT signaling, it is thought to help reduce immune-mediated processes that contribute to loss of skin pigmentation.1,2,4
For more details, visit the Mechanism of Action page.
The IFN-γ-mediated JAK-STAT signaling pathway plays a role in immune signaling processes associated with nonsegmental vitiligo, including pathways that contribute to melanocyte dysfunction and loss of skin pigmentation.1,4,5
Efficacy & Clinical Results
Clinical trials of OPZELURA in patients with nonsegmental vitiligo demonstrated improvements in repigmentation of both facial and body areas. These endpoints were assessed using validated measures, including the Facial Vitiligo Area Scoring Index (F-VASI) and Total Vitiligo Area Scoring Index (T-VASI), which evaluate changes in depigmentation over time.1,7
In clinical studies of patients with nonsegmental vitiligo, ≈30% of patients treated with OPZELURA since Day 1 achieved at least 75% improvement in facial repigmentation (F-VASI75) at Week 24, and ≈51% of patients achieved F-VASI75 at Week 52. These results reflect clinically meaningful improvement in facial pigmentation over time.1,7

In clinical studies of patients with nonsegmental vitiligo, 51% of patients treated with OPZELURA since Day 1 achieved at least 50% improvement in total body repigmentation (T-VASI50) at Week 52. These results reflect improvement in repigmentation of nonfacial areas over time.7

Repigmentation with OPZELURA for nonsegmental vitiligo may be observed over time, with clinical studies evaluating outcomes at 24 weeks and beyond. Improvements in repigmentation can continue with ongoing treatment, and results may vary depending on the individual and the area of skin being treated.1,8
Dosing
OPZELURA is applied as a thin layer twice daily to the affected areas of skin with nonsegmental vitiligo, covering up to 10% of the body surface area.1
It may be applied to sensitive skin areas, including around the eyes and mouth and on external genital areas.1
It is for topical use only and should not be used in the eyes, mouth, or intravaginally.1
See full guidance on the Dosing and Administration page.
The duration of treatment with OPZELURA in nonsegmental vitiligo may vary based on patient response and treatment goals. Clinical studies evaluated repigmentation outcomes over 2 years, with continued improvement observed with ongoing use. Treatment decisions should be based on clinical assessment of response over time.1
Patients starting OPZELURA for nonsegmental vitiligo can expect repigmentation to occur gradually and vary by individual and treatment area. Clinical studies evaluated outcomes over 24 weeks and beyond, with continued improvement observed with ongoing use. Consistent twice-daily application supports assessment of treatment response over time.1,8
