LONG BEACH, Calif., and BASEL, Switzerland, March 11, 2022—Dermavant Sciences, a clinical-stage biopharmaceutical company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology, today announced that new data from the Phase 3 PSOARING 3 long-term extension study of tapinarof cream for the treatment of plaque psoriasis in adults (PSOARING 3), will be presented at the 2022 American Academy of Dermatology (AAD) Annual Meeting, to be held March 25-29 in Boston.

Tapinarof is a novel, non-steroidal, once-daily therapeutic aryl hydrocarbon receptor modulating agent which is formulated in a cosmetically elegant cream. It is being developed for the treatment of plaque psoriasis and atopic dermatitis. In August 2021, the U.S. Food and Drug Administration (FDA) accepted for filing the company’s New Drug Application for tapinarof for the treatment of plaque psoriasis in adults. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date in Q2 2022.

The following posters will be viewable in the exhibit hall at the Boston Convention and Exhibition Center:

About Dermavant’s Phase 3 Program for Tapinarof in Psoriasis

Dermavant’s Phase 3 clinical program for tapinarof in adult plaque psoriasis consists of two pivotal studies, PSOARING 1 (NCT03956355) and PSOARING 2 (NCT03983980), as well as PSOARING 3 (NCT04053387), a long-term extension study.

PSOARING 1 and PSOARING 2, which collectively enrolled 1,025 patients, were two identically designed, multi-center, randomized, vehicle-controlled, double-blind, parallel group studies conducted in North America that evaluated the safety and efficacy of tapinarof cream, 1% dosed once daily (QD) for 12 weeks versus vehicle QD in adult patients aged 18-75 years diagnosed with plaque psoriasis. The primary endpoint of both studies was the proportion of patients who achieved a PGA score of clear (0) or almost clear (1) with a minimum 2-grade improvement from baseline at Week 12.

PSOARING 3 was a long-term, open-label, extension study to evaluate the safety and efficacy of tapinarof cream, 1% for the treatment of plaque psoriasis in adults. Patients in the study had previously completed treatment with tapinarof or vehicle in either the PSOARING 1 or PSOARING 2 Phase 3 pivotal efficacy and safety studies. PSOARING 3 consisted of up to 40 weeks of tapinarof cream, 1%, and a 4-week safety follow-up period. As such, patients who received drug during PSOARING 1 and PSOARING 2 and completed PSOARING 3, received treatment with tapinarof cream for up to 52 weeks. Greater than 90% of eligible patients who completed PSOARING 1 and PSOARING 2 enrolled in PSOARING 3. Dermavant released interim analysis results from PSOARING 3 in February 2021 and full analysis results from PSOARING 3 in September 2021.

About Psoriasis

Psoriasis is a chronic, systemic, inflammatory skin disease characterized by red patches and plaques with silvery scales on the skin. Psoriasis affects approximately 8 million people in the United States and 125 million worldwide.

Psoriasis can begin at any age, but typically has two peaks of onset, the first at age 20 to 30 years and the second at age 50 to 60 years. People with psoriasis are at an increased risk of developing other chronic and serious health conditions. Comorbidities include psoriatic arthritis, inflammatory bowel disease, hypertension, diabetes, obesity, and depression. Psoriasis has a significant impact on quality of life and on psychological health.
