November 21, 2017 at 12:00 PM EST

REDWOOD CITY, Calif., November 21, 2017 /PRNewswire/ — Menlo Therapeutics Inc., a late- stage biopharmaceutical company developing a neurokinin 1 (NK‐1) receptor antagonist (serlopitant) for the treatment of pruritus (itch) and refractory chronic cough, has initiated enrollment in a new Phase 2 clinical trial evaluating serlopitant for the treatment of pruritus associated with psoriasis.

The PSORIXA study, MTI-109, is a multi-center, randomized, placebo-controlled study evaluating the efficacy, safety, and tolerability of serlopitant for the treatment of pruritus associated with psoriasis. The PSORIXA study will enroll approximately 200 patients at approximately 40 clinical sites in the U.S. Additional study information is available on clinicaltrials.gov ( NCT03343639 ).

There are an estimated 12 million people in the United States who have psoriasis, a common chronic autoimmune disorder of the skin, causing redness, irritation and scaly lesions. In a recent survey of 5,604 psoriasis patients, over 90% reported pruritus as a significantly bothersome symptom.

About Serlopitant
Serlopitant is a once-daily NK-1 receptor antagonist being developed for the treatment of pruritus, or itch, associated with atopic dermatitis, psoriasis, and prurigo nodularis. Serlopitant is also being evaluated as a potential treatment for refractory chronic cough, a cough which persists for greater than eight weeks despite treatment of any identified underlying cause. Menlo Therapeutics has completed two Phase 2 studies with serlopitant showing a statistically significant reduction in pruritus compared to placebo. Originally developed by Merck and licensed to Menlo Therapeutics in 2012, serlopitant has been evaluated in more than 1,000 patients and has been shown to be well-tolerated, including in patients who have received treatment for up to a year. Serlopitant is an investigational drug that is not currently approved for use in any indication.
