Incyte (Nasdaq:INCY) today announced positive topline results from its pivotal Phase 3 TRuE-V clinical trial program evaluating the safety and efficacy of ruxolitinib cream, an investigational, nonsteroidal, anti-inflammatory, JAK inhibitor, topical therapy, in adolescent and adult patients (age ≥12 years) with vitiligo.
Both the TRuE-V1 and TRuE-V2 studies met the primary endpoint (p<0.0001 for both studies), demonstrating that significantly more patients treated with ruxolitinib cream 1.5% twice daily (BID) achieved a ≥75% improvement from baseline in the facial vitiligo area scoring index (F-VASI75) compared to patients treated with a vehicle control at Week 24.
The studies also met key secondary endpoints including patient reported outcomes. The overall efficacy and safety profile of ruxolitinib cream is consistent with previously reported Phase 2 data, and no new safety signals were observed. The long-term efficacy and safety portions of both studies will continue as planned. Additionally, data from both studies will be submitted for publication and presentation at an upcoming scientific meeting in the second half of 2021.
"These positive results - the first Phase 3 data to demonstrate significant improvements in facial and total body repigmentation - confirm the potential of ruxolitinib cream to be a meaningful treatment option for individuals living with and seeking treatment for their vitiligo," said Jim Lee, M.D., Group Vice President, Inflammation & Autoimmunity, Incyte. "We look forward to working with regulators to bring this much needed treatment option to patients. If approved, ruxolitinib cream would be the first and only medical treatment for repigmentation in vitiligo."
Based on these findings, Incyte plans to submit marketing applications for ruxolitinib cream for the treatment of adolescent and adult patients with vitiligo (age ≥12 years) to the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) in the second half of 2021. The FDA is currently reviewing a New Drug Application (NDA) for ruxolitinib cream for the treatment of adolescents and adults (age ≥12 years) with atopic dermatitis, a type of eczema.
"Vitiligo is a chronic immune-mediated skin condition that can significantly impact quality of life for those living with, and suffering from, this disease," said David Rosmarin, M.D., Vice Chair of Research and Education, Dermatology Department at Tufts Medical Center. "As a clinician, I am extremely encouraged by the initial findings from the TRuE-V program and the potential to have ruxolitinib cream as a future topical treatment option for vitiligo patients, who currently have limited therapies available that effectively and safely address repigmentation."
About VitiligoVitiligo is a chronic autoimmune disease characterized by depigmentation of skin that results from the loss of pigment-producing cells known as melanocytes. Over-activity of the JAK signaling pathway has been shown to drive inflammation involved in the pathogenesis and progression of vitiligo. It affects approximately 0.5% to 2.0% of the population globally 1 and there are no U.S. Food and Drug Administration (FDA) or European Medicines Agency (EMA)-approved drug therapies for the treatment of vitiligo. It can occur at any age, although many patients with vitiligo will experience initial symptoms before the age of 20 2.
About TRuE-VThe TRuE-V clinical trial program includes two Phase 3 studies, TRuE-V1 (NCT04052425) and TRuE-V2 (NCT04057573), evaluating the safety and efficacy of ruxolitinib cream in patients with vitiligo.
The studies each enrolled approximately 300 patients (age ≥12 years) who have been diagnosed with non-segmental vitiligo and have depigmented areas including at least 0.5% of the body surface area (BSA) on the face, ≥0.5 facial vitiligo area severity index [F-VASI] score, at least 3% BSA on nonfacial areas, ≥3 total body Vitiligo Area Scoring Index [T-VASI] score and total BSA involvement (facial and nonfacial) of up to 10%. Participants were randomized into two arms: 1.5% ruxolitinib cream twice daily (BID) and vehicle control for the 24-week double-blind period. Patients who successfully completed baseline and Week 24 assessments, including those that received vehicle control during the double-blind phase, were offered treatment extension with 1.5% ruxolitinib cream BID for an additional 28 weeks.
The primary endpoint of both studies in the TRuE-V program is the proportion of patients achieving F-VASI75, defined as at least a 75% improvement from baseline in the F-VASI score at Week 24. Key secondary endpoints include: the percentage change from baseline in facial BSA (F-BSA) at Week 24, the proportion of patients achieving F-VASI50 (at least 50% improvement from baseline in the F-VASI), F-VASI90 (at least 90% improvement from baseline in the F-VASI) and T-VASI50 (at least 50% improvement from baseline in the T-VASI) at Week 24, the proportion of patients achieving F-VASI75, F-VASI90, T-VASI50 and T-VASI75 (at least 75% improvement from baseline in the T-VASI) at Week 52 and the proportion of patients achieving a Vitiligo Noticeability Scale (VNS) score of 4 (a lot less noticeable) or 5 (no longer noticeable) at Week 24. The studies also track the frequency, duration and severity of adverse events associated with the use of ruxolitinib cream.
