LONG BEACH, Calif. & BASEL, Switzerland--(BUSINESS WIRE)-- Dermavant Sciences Inc., a biopharmaceutical company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology, today announced that it has completed patient enrollment in its ADORING 1 and 2 Phase 3 clinical trials of VTAMA (tapinarof) cream, 1% for the topical treatment of atopic dermatitis (AD) in adults and children as young as 2 years old.

VTAMA cream is a novel, aryl hydrocarbon receptor agonist, in development as a once-daily, steroid-free and cosmetically elegant topical cream for the treatment of AD. In the U.S., VTAMA cream is approved for the topical treatment of plaque psoriasis in adults – with no label safety warnings or precautions, restrictions on duration of use or body surface area. Dermavant is developing VTAMA cream for atopic dermatitis using the same dose and regimen already FDA-approved for plaque psoriasis.

“We are delighted to have completed enrollment in our ADORING 1 and 2 Phase 3 pivotal trials of VTAMA in atopic dermatitis, a chronic inflammatory skin condition with significant unmet medical need, especially in children,” said Todd Zavodnick, Chief Executive Officer of Dermavant. “The potential expansion of our VTAMA franchise to include atopic dermatitis represents a major growth opportunity for Dermavant, as plaque psoriasis and atopic dermatitis represent the two largest markets in immuno-dermatology. We are excited about the potential for VTAMA cream to be a novel and highly differentiated treatment option for patients as young as 2 years old who suffer from atopic dermatitis. We’re encouraged by the progress we are making in our ADORING program and look forward to sharing the topline results from both Phase 3 studies in the first half of 2023.”

Dermavant recently published highly favorable results from a pediatric maximal usage pharmacokinetics (MUPK) study of VTAMA cream in atopic dermatitis. The study demonstrated minimal-to-no systemic exposure despite maximal use. In addition, subjects were as young as 2 years old with up to 90% body surface area (BSA) affected with a mean BSA of 43%.

On May 24, 2022, Dermavant announced that the FDA had approved VTAMA (tapinarof) cream, 1% for the treatment of adult plaque psoriasis. The approval made VTAMA cream the first topical novel chemical entity launched for psoriasis in the U.S. in more than 25 years. VTAMA cream is approved for mild, moderate, and severe plaque psoriasis with no restrictions on duration of use or body surface area, as demonstrated up to 52 weeks in the open-label, long-term extension study, and with a demonstrated median remittive “off-treatment” effect of approximately 4 months. Durability of response up to 52 weeks was demonstrated with intermittent use of VTAMA cream, with no evidence of tachyphylaxis (loss of response) while on therapy. As of July 15, 2022, VTAMA cream is the #1 prescribed branded topical treatment for plaque psoriasis.ⁱ

About Dermavant’s Phase 3 Program for VTAMA cream in Atopic Dermatitis

Dermavant’s pivotal Phase 3 clinical program for VTAMA (tapinarof) cream, 1% in atopic dermatitis consists of two identical pivotal trials (ADORING 1 and ADORING 2), followed by an open-label, long-term extension study (ADORING 3).

ADORING 1 and ADORING 2 are two identical, multi-center, randomized, vehicle-controlled, double-blind, parallel group studies being conducted in North America. The Phase 3 clinical program enrolled 813 patients across the two pivotal trials to evaluate the safety and efficacy of VTAMA cream, 1% dosed once daily (QD) for 8 weeks versus vehicle cream QD in patients aged 2 years and older diagnosed with moderate to severe AD. The primary endpoint of both clinical trials is the percentage of patients achieving a vIGA-AD™ (Validated Investigator Global Assessment for Atopic Dermatitis) of 0 or 1 with at least a 2-grade improvement from baseline at week 8.

ADORING 3 is a long-term, open-label, extension study to evaluate the safety and efficacy of VTAMA cream, 1% in patients with AD. The trial includes eligible patients who have completed treatment with VTAMA cream or vehicle in Phase 3 trials. ADORING 3 consists of up to 48 weeks with treatment of VTAMA cream, 1%, and a 7-day safety follow-up period.

About Atopic Dermatitis

Atopic Dermatitis (AD), commonly referred to as eczema, is one of the most common inflammatory skin diseases, affecting over 28 million people in the U.S. alone and up to 10% of adults worldwide. AD occurs most frequently in children, affecting up to 30% worldwide. The disease results in itchy, red, swollen, and cracked skin, often affecting the folds of the arms, back of the knees, hands, face, and neck. Itching is an especially bothersome symptom in AD, and tends to worsen at night, disturbing sleep and causing fatigue, which in children can lead to inattention at school. People with AD may also experience social and emotional distress due to the visibility and discomfort of the disease.
