The approval is based on data from two multicenter, randomized, double-blind, placebo-controlled Phase 3 clinical trials THRIVE-AA1 and THRIVE-AA2, which enrolled a total of 1,220 patients with alopecia areata who had at least 50% scalp hair loss as measured by Severity of Alopecia Tool (SALT) for more than six months. Data were also collected from two open-label, long-term extension trials in which patients were eligible to enroll upon completion of the 24-week trials.
At study baseline, the average patient had only 13% of their scalp hair coverage.
“In the trials, at 24 weeks, the primary endpoint was met, with more than 30% of patients taking Leqselvi (deuruxolitinib) experiencing 80% or more scalp hair coverage (SALT ≤20),” the company said.
“The number of patients taking LEQSELVI and achieving a SALT score of ≤20 showed a consistent upward trend with no plateau through 24 weeks. Additionally, up to 25% of patients had almost all of their scalp hair back at 24 weeks,” it added.
