Dermavant Showcases New Long-Term Durability and Tolerability Data from Phase 3 PSOARING 3 Trial of Tapinarof Cream for Adults with Plaque Psoriasis at the 2022 AAD Annual Meeting
Dermavant Sciences announced positive results from the Phase 3 PSOARING 3 long-term extension study for tapinarof cream 1% in treating plaque psoriasis. Over 52 weeks, tapinarof showed durable improvements in efficacy, quality of life, and tolerability without irritation. The study demonstrated significant enhancements in key metrics such as % body surface area (%BSA) affected and Psoriasis Area and Severity Index (PASI). Dermavant aims for FDA approval, with a target action date set for Q2 2022, which could position tapinarof as a novel therapeutic option for psoriasis patients.
- Tapinarof demonstrated continued improvements in efficacy outcomes over 52 weeks.
- Showed no associated tachyphylaxis, indicating sustained effectiveness.
- Well-tolerated by patients with no irritation reported in sensitive areas.
- Potential first-in-class treatment for plaque psoriasis pending FDA approval.
- None.
- Tapinarof demonstrated continued improvements for up to 52 weeks in efficacy outcomes, quality of life measures, and tolerability scores with no associated tachyphylaxis
- Tapinarof was well-tolerated in sensitive skin and intertriginous areas with majority of patients experiencing no irritation for up to 52 weeks
- Tapinarof was well tolerated with long term use and demonstrated continued and durable improvement in quality of life
LONG BEACH, Calif., and BASEL, Switzerland, March 25, 2022 (GLOBE NEWSWIRE) -- Dermavant Sciences, a clinical-stage biopharmaceutical company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology, today announced Phase 3 PSOARING 3 long-term extension study results demonstrating durable improvements across efficacy outcomes, quality of life measures, and tolerability scores with investigational tapinarof cream
“Plaque psoriasis is often a lifelong condition that can have a significant negative impact on many aspects of a patient’s life. Due to limitations in current psoriasis therapies, there is a strong need for new topical treatments for adults suffering with this condition,” said April W. Armstrong, M.D., M.P.H., a dermatologist with Keck Medicine of USC and Professor of Dermatology and Associate Dean for Clinical Research in Dermatology at the Keck School of Medicine of USC. “The durable improvements demonstrated by tapinarof in PSOARING 3 across efficacy outcomes, quality of life and tolerability scores are encouraging. As a clinician, I am excited about the possibility of a potential new therapy in tapinarof for patients suffering from plaque psoriasis.”
Eligible patients who completed either PSOARING 1 or 2, which were 12-week pivotal studies of tapinarof in adults with plaque psoriasis, could enroll in PSOARING 3. PSOARING 3 consisted of an additional 40 weeks of open-label intermittent treatment with tapinarof based on Physician Global Assessment (PGA) score, followed by a 4-week follow-up. Patients who were randomized to tapinarof in PSOARING 1 or 2 and who also completed PSOARING 3 received tapinarof treatment for up to 52 weeks.
These newly presented data include prespecified analyses of key secondary efficacy outcomes, quality of life and tolerability assessments. Importantly, continued improvements were observed in all assessments beyond the responses observed in the 12-week pivotal studies. Efficacy outcomes include changes in percentage body surface area (%BSA) affected and in Psoriasis Area and Severity Index (PASI), which is a measurement of the severity and extent of psoriasis. Quality of life outcomes included changes in Dermatology Life Quality Index (DLQI), and tolerability assessments included both patient-reported tolerability and investigator-assessments of irritation at all sites of drug application.
- Investigators rated the majority of patients as having no irritation (score of 0), including those who applied tapinarof to sensitive skin and intertriginous areas at all time points across 40 weeks
- Long-term treatment with tapinarof cream
1% QD for up to 52 weeks demonstrated continued and durable improvement in mean PASI score, PASI75, PASI90, %BSA Affected, DLQI, and local tolerability scores
“We are pleased to report data demonstrating continued improvements in efficacy and patient reported outcomes with use of tapinarof cream
In August 2021, the U.S. Food and Drug Administration accepted a New Drug Application for tapinarof cream
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,
PSOARING 3 was a long-term, open-label, extension study to evaluate the safety and efficacy of tapinarof cream,
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.
