Incyte Announces First Patient Treated in Phase 3 Clinical Trial Program Evaluating Ruxolitinib Cream in Patients with Vitiligo
“Vitiligo is a challenging and life-altering disease further complicated by the lack of effective treatment options available to physicians and their patients,” said
Vitiligo is a chronic autoimmune disease characterized by depigmentation of skin that results from the loss of pigment-producing cells known as melanocytes. It affects approximately 0.5 percent to 2.0 percent of the population globally1 and there are no
The 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 will each enroll approximately 300 patients (age ≥12 years) who have been diagnosed with non-segmental vitiligo and have depigmented areas including at least 0.5 percent of the body surface area (BSA) on the face, ≥0.5 facial vitiligo area severity index [F-VASI] score, at least 3 percent 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 percent. Participants will be randomized to two arms: 1.5 percent ruxolitinib cream twice daily (BID) and vehicle control for the 24-week double-blind period. Patients who successfully complete baseline and Week 24 assessments, including those that received vehicle control during the double-blind phase, will be offered treatment extension with 1.5 percent 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 percent improvement from baseline in the F-VASI score at Week 24. Key secondary endpoints include: the percentage change from baseline in facial BSA at Week 24, the proportion of patients achieving F-VASI50 (at least 50 percent improvement from baseline in the F-VASI), F-VASI90 (at least 90 percent improvement from baseline in the F-VASI) and T-VASI50 (at least 50 percent 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 percent 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 will also track the frequency, duration and severity of adverse events associated with the use of ruxolitinib cream.
About Ruxolitinib Cream
Ruxolitinib cream is a proprietary formulation of Incyte’s selective JAK1/JAK2 inhibitor ruxolitinib that has been designed for topical application. Ruxolitinib cream is currently in Phase 3 development for the treatment of patients with mild to moderate atopic dermatitis (TRuE-AD) with initial results expected in the first half of 2020, and for the treatment of adolescents and adults with vitiligo (TRuE-V).
