Menlo Gains Breakthrough Status for Pruritus Therapy
FDA has granted Menlo Therapeutics a breakthrough therapy designation for serlopitant for treating pruritus associated with prurigo nodularis (PN). The designation is based on data from a Phase 2 clinical trial in pruritus associated with PN, according to the company. In the 127-patient trial, serlopitant met its primary and multiple secondary efficacy endpoints, it says. At week eight, the serlopitant 5 mg group showed a 36 mm improvement from baseline in average itch (measured by the itch visual analog scale) compared with a 19 mm improvement for the placebo group, Menlo says. Currently, patients are enrolling in two Phase 3 clinical trials (one in the U.S. and one in Europe) to evaluate the indication, with data expected by the first quarter of 2020. Serlopitant is a once-daily oral NK1 receptor antagonist being developed for the treatment of pruritus associated with various conditions such as prurigo nodularis, psoriasis and chronic pruritus of unknown origin.
