Introduction/Background Vitiligo is a chronic autoimmune disease characterized by melanocyte destruction, leading to skin depigmentation. Limited data are available regarding the efficacy of long-term topical vitiligo treatment. In 2 randomized, double-blinded, vehicle-controlled phase 3 studies in adults and adolescents (aged ≥12 y) with nonsegmental vitiligo (TRuE-V1 [NCT04052425]; TRuE-V2 [NCT04057573]), ruxolitinib cream application resulted in statistically superior improvements in repigmentation versus vehicle in the primary and all key secondary endpoints at Week 24 and was well tolerated. In the open-label period of TRuE-V1/TRuE-V2 (Weeks 24-52) and the TRuE-V long-term extension (LTE; Weeks 52-104) study (NCT04530344), further improvements in facial and body repigmentation (as assessed by Vitiligo Area Scoring Index [VASI] responses) were observed through Week 104 among patients who continued to apply ruxolitinib cream. Objectives: In this pooled analysis, we evaluated shifts in facial and total body VASI (F-VASI/T-VASI) responses among patients with vitiligo who had limited or no repigmentation at Week 24 and who continued to apply ruxolitinib cream for an additional 80 weeks. Methods: In TRuE-V1/TRuE-V2, patients were randomized 2:1 to apply twice-daily 1.5% ruxolitinib cream or vehicle for 24 weeks, after which all patients could apply 1.5% ruxolitinib cream through Week 52. Patients who completed TRuE-V1/TRuE-V2 were eligible to enroll in the TRuE-V LTE. Patients who did not achieve ≥90% improvement in F-VASI at Week 52 continued to apply open-label 1.5% ruxolitinib cream until Week 104. Patients initially randomized to apply ruxolitinib cream who had <25% improvement from baseline in F-VASI or T-VASI at Week 24 and had non-missing VASI assessments at the evaluated time points were included in this analysis. Shifts in F-VASI and T-VASI were assessed among patients with no facial/body repigmentation or worsening depigmentation (≤0% improvement in F-VASI/T-VASI) and patients with limited facial/body repigmentation (>0%- <25% improvement in F-VASI/T-VASI) at Week 24. Results: Among patients with no facial repigmentation at Week 24, improvements in F-VASI at Weeks 52 and 104 were observed in 77.8% (49/63) and 97.1% (34/35) of patients, respectively. Among patients with limited facial repigmentation at Week 24, F-VASI improvements at Weeks 52 and 104 were observed in 64.0% (32/50) and 83.3% (30/36) of patients, respectively. Across both groups, 54.9% (39/71) of patients achieved =75% improvement from baseline in F-VASI (F-VASI75) at Week 104. Among those with no body repigmentation at Week 24, T-VASI improvements at Weeks 52 and 104 were observed in 79.6% (39/49) and 93.3% (28/30) of patients, respectively. For those with limited body repigmentation at Week 24, T-VASI improvements at Weeks 52 and 104 were observed in 64.5% (80/124) and 81.6% (62/76) of patients, respectively. Across both groups who had <25% improvement in total body repigmentation at Week 24, 50.0% (53/106) of patients achieved ≥50% improvement in T-VASI (T-VASI50) at Week 104. Conclusions: In the TRuE-V studies, ruxolitinib cream application for an additional 80 weeks resulted in improved repigmentation among patients with nonsegmental vitiligo who had limited or no repigmentation at Week 24. These 2-year TRuE-V results highlight the importance of prolonged treatment in patients with vitiligo, even when minimal or no repigmentation is achieved after 6 months of treatment.
