– Psoriasis Impacts Approximately 8 Million Americans and 125 Million People Worldwide
– NDA Is Supported by Positive Data From the Phase 3 PSOARING 1 and PSOARING 2 Pivotal Efficacy Trials and Interim Results From the PSOARING 3 Long-Term Safety Study
– FDA PDUFA Action Expected in Q2 2022
LONG BEACH, Calif., and BASEL, Switzerland, August 10, 2021—Dermavant Sciences, a clinical-stage biopharmaceutical company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology, today announced that the U.S. Food and Drug Administration (FDA) accepted for filing the company’s New Drug Application (NDA) for tapinarof for the treatment of plaque psoriasis in adult patients.
Tapinarof is an investigational, novel, therapeutic aryl hydrocarbon receptor modulating agent, in development as a once-daily, steroid-free and cosmetically elegant topical cream for the treatment of plaque psoriasis and atopic dermatitis. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date in Q2 2022. The company submitted the NDA to the FDA on May 26, 2021.
Estimates suggest that psoriasis, a chronic and debilitating condition, impacts 8 million people in the United States and 125 million people worldwide. Plaque psoriasis, also called psoriasis vulgaris, is the most common form and affects about 80–90% of people with psoriasis.
“With the FDA acceptance of our NDA for filing, Dermavant is one step closer to potentially providing a new option for adults with mild, moderate, and severe plaque psoriasis, who often deal with itch, pain, disfiguring appearance, and significant emotional and physical distress,” said Todd Zavodnick, Chief Executive Officer of Dermavant. “The entire Dermavant team is now working diligently to prepare for the commercial launch of tapinarof, subject to FDA approval, and we look forward to further discussions with the FDA during the review process of this novel product candidate.”
The regulatory application is supported by positive Phase 3 data from PSOARING 1 and PSOARING 2, two replicate, multi-center, randomized, vehicle-controlled, double-blind studies, as well as the interim results from PSOARING 3, a 40-week, open-label safety study.
About Dermavant’s Phase 3 Program for Tapinarof in Psoriasis
Dermavant’s pivotal Phase 3 clinical program for tapinarof in adult plaque psoriasis consists of 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 completed PSOARING 3, having 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 the study completed on April 5, 2021.
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.
