A study published in the Journal of the American Academy of Dermatology did a subgroup analysis of ruxolitinib cream for vitiligo patients.
A randomized phase 2 study (NCT03099304) of the Janus kinase (JAK) 1/ JAK 2 inhibitor ruxolitinib (Opzelura; Incyte and Novartis) cream was investigated as a treatment of facial and body vitiligo.1
The study included 157 patients and showed that patients on ruxolitinib achieved substantial regimentation after 24 weeks and continued improvement through week 52. Ruxolitinib was also well-tolerated.
The article did a sub-analysis of the trial. Of the 33 patients who received 1.5% ruxolitinib cream twice daily, greater than or equal to 50% of them achieved facial Vitiligo Area Scoring Index (F-VASI50) improvement at week 24, which was assessed by demographics and baseline clinical characteristics.
Also, a larger proportion of the patients who were less than or equal to 50 years old achieved F-VASI50 compared to those older than 50 years (58.8% vs 31.3%, respectively). More were female vs male (60.0% vs 33.3%). A larger proportion of responders had less than or equal to 1.5% affected baseline facial body surface area (BSA), a disease duration of more than 20 years, and previous treatment with phototherapy. There were no substantial differences between responders based on race, skin type, baseline total (T)-BSA, or disease status.
The proportion of patients initially randomized to 1.5% ruxolitinib cream once daily or twice daily that achieved greater than or equal to 50% and greater than or equal to 75% improvement from baseline in total VASI (T-VASI50 and T-VASI75, respectively) at week 52 was assessed by affected body area.
The ruxolitinib cream application was limited to less than or equal to 20% T-BSA—the limit for the practicality of application— and the total body analyses were conducted only in patients with vitiligo affecting less than or equal to 20% T-BSA at baseline.
T-VASI50 and T-VASI75 responses were seen among patients with vitiligo affecting 20% or less of their T-BSA by week 52 in both the once daily and twice daily 1.5% ruxolitinib cream applications. The twice daily application patients had the highest proportion of T-VASI50 responders in the head/neck area (60%), followed by the upper and lower extremities (52.9%, 52.6%, respectively), feet (29.45%) and the hands (15%), according to the article.
Ruxolitinib cream 1.5% demonstrated positive trends for treating vitiligo across demographics and clinical characteristics, including in patients with longstanding and extensive disease, the authors summarized.
There were F-VASI50 responses observed in more than 40% of patients that were previously treated with topical corticosteroids or topical calcineurin inhibitors and in 66% of patients who received prior phototherapy. Ruxolitinib cream also produced a clinically meaningful repigmentation of all body areas, including acral areas.
“Overall, these findings support the use of ruxolitinib cream for treating vitiligo,” the authors concluded. “Reported analyses were descriptive, and sample sizes were small, warranting confirmation of results in larger populations.”
