Dermavant Reports Positive Topline Results from ADORING 1, the Second Atopic Dermatitis Phase 3 Trial of VTAMA® (tapinarof) Cream, 1% in Adults and Children as Young as 2 Years Old

• 45.4% of subjects receiving VTAMA achieved the primary endpoint of vIGA-AD^TM response of clear (0) or almost clear (1) with at least a 2-grade improvement from baseline at Week 8, versus 13.9% on vehicle (P<0.0001)
• All secondary endpoints were met with statistical significance, including 55.8% of subjects treated with VTAMA who achieved the key secondary endpoint of EASI75 at Week 8 (P<0.0001)
• Meaningful impact on the exploratory endpoint of pruritus (itch) was demonstrated with 61.1% of subjects, with a baseline PP-NRS score ≥4, achieving a ≥4-point reduction in the PP-NRS at Week 8 (P<0.0001)
• 91% of subjects from ADORING 1 & 2 elected to enroll into the Phase 3 ADORING 3 open-label, long-term safety study^*
• ADORING 1 met the primary and all key secondary endpoints, consistent with the positive topline results from the Phase 3 ADORING 2 trial reported in March
• sNDA for VTAMA in atopic dermatitis anticipated to be filed with the FDA in Q1 2024

LONG BEACH, Calif. & BASEL, Switzerland--(BUSINESS WIRE)--Dermavant Sciences, a clinical-stage biopharmaceutical company dedicated to developing and commercializing innovative therapeutics in immuno-dermatology, today announced positive results from ADORING 1, the second of two double-blind, randomized, vehicle-controlled Phase 3 studies to evaluate the efficacy and safety of topical VTAMA® (tapinarof) cream, 1% in adults and pediatric subjects down to 2 years old with moderate to severe atopic dermatitis (AD).

In ADORING 1 (N=407), VTAMA met the primary endpoint of the trial and demonstrated highly statistically significant improvement in the Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD^TM) score of clear (0) or almost clear (1) with at least a 2-grade improvement from baseline at Week 8 (P<0.0001).

Additionally, VTAMA demonstrated highly statistically significant improvement in the proportion of subjects with ≥75% improvement in the Eczema Area and Severity Index (EASI75) from baseline at Week 8 (P<0.0001), a key secondary endpoint. Subjects 12 years and older receiving VTAMA also experienced a statistically significant improvement in itch with a ≥4-point reduction in the patient reported Peak Pruritus Numeric Rating Scale (PP-NRS) (P=0.0366), another key secondary endpoint.

Table 1: ADORING 1 and ADORING 2 Phase 3 Trials – Primary and Key Secondary Endpoints

	ADORING 1  Week 8			ADORING 2 Week 8
Endpoint	VTAMA 1% QD	Vehicle QD	P Value	VTAMA 1% QD	Vehicle QD	P Value
vIGA-AD success^1	45.4%	13.9%	<0.0001	46.4%	18.0%	<0.0001
EASI75^2	55.8%	22.9%	<0.0001	59.1%	21.2%	<0.0001
≥4-point reduction in PP-NRS^3	55.8%	34.2%	0.0366	52.8%	24.1%	0.0015

¹Primary Endpoint: Proportion of subjects who achieved a vIGA-AD score of clear (0) or almost clear (1) with at least a 2-grade improvement from baseline at Week 8.
²Secondary Endpoint: Proportion of subjects with ≥75% improvement in EASI from baseline at Week 8.
³Secondary Endpoint: Proportion of subjects ≥12 years old with a baseline PP-NRS score ≥4 who achieved ≥4-point reduction in the PP-NRS from baseline at Week 8.

Importantly, when PP-NRS was assessed across the entire VTAMA treated population, 61.1% (P<0.0001) experienced a statistically significant improvement in itch, a highly prevalent symptom among AD sufferers.

Both adult and pediatric AD subjects down to 2 years of age receiving VTAMA in the ADORING trials did so at the same dose and dose regimen as currently approved for adults with plaque psoriasis. Subject to FDA approval in AD, the company believes this could be a key manufacturing, supply chain, and commercial advantage, offering simplicity of treatment to patients, physicians, pharmacists, and payers, regardless of plaque psoriasis or atopic dermatitis diagnosis.

“I am extremely proud to share the positive results from ADORING 1, the second of our two Phase 3 pivotal trials with VTAMA in adults and children as young as 2 years old with moderate to severe atopic dermatitis,” said Philip M. Brown, MD, JD, Chief Medical Officer at Dermavant. “Similar to our ADORING 2 data, VTAMA hit all its primary and secondary endpoints. Subject to FDA approval, we believe that the positive safety and efficacy profile of VTAMA, combined with its treatment simplicity, has the potential to change the approach in the way patients are treated. The success of the ADORING studies marks a significant milestone for the entire Dermavant team, and I would like to extend my heartfelt thanks to the patients and investigators involved in our clinical studies.”

VTAMA 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 is currently approved for the topical treatment of plaque psoriasis in adults.

Topline Results

In ADORING 1, adult and pediatric subjects down to 2 years of age with moderate to severe AD were randomized at a 2:1 ratio to receive once daily (QD) treatment with VTAMA or vehicle cream.

• At Week 8, 45.4% of subjects treated with VTAMA in ADORING 1 achieved the primary endpoint of a vIGA-AD of clear (0) or almost clear (1) with at least a 2-grade improvement from baseline at Week 8 (P<0.0001).
• Also at Week 8, 55.8% of subjects treated with VTAMA in ADORING 1 achieved the key secondary endpoint of the proportion of subjects with ≥75% improvement in EASI (P<0.0001).
• 55.8% of subjects ≥12 years old, with a baseline PP-NRS score ≥4, achieved a ≥4-point reduction in the PP-NRS at Week 8 (P=0.0366).
• Importantly, VTAMA data indicated no new safety or tolerability signals in this population including children as young as 2 years old. Adverse events were mostly mild to moderate with a low study discontinuation rate due to adverse events (1.9% VTAMA vs. 3.6% vehicle).
• Adverse events of special interest included contact dermatitis (1.5% VTAMA vs. 2.2% vehicle) and follicular event (10.0% VTAMA vs. 0.7% vehicle).

“Atopic dermatitis affects a significant number of children, and its prevalence continues to grow. Given the increasing need for an effective and well-tolerated, non-steroidal topical treatment option for the pediatric population, the efficacy and safety data from ADORING 1 results are encouraging and, combined with the positive results from the maximal usage pharmacokinetics (MUPK) study, VTAMA appears to have the potential to bring relief to children suffering from this disease,” said Adelaide A. Hebert, MD, professor and chief of pediatric dermatology at McGovern Medical School at UTHealth Houston and Children’s Memorial Hermann. “The prevalence of itch as an associated symptom makes this condition extremely burdensome not only to the patients suffering from AD, but also their families. In this regard, the itch data from ADORING 1, much like that from ADORING 2, emphasizes VTAMA’s effectiveness when it comes to disease control and VTAMA’s potential to reduce one of atopic dermatitis’ most burdensome symptoms.”

“It is a really exciting time for patients suffering from atopic dermatitis and clinicians who treat them. The positive topline data from ADORING 1 taken together with the positive results previously shown in ADORING 2 indicate that VTAMA has potential as a new non-steroidal topical medication option in atopic dermatitis, that can be used anywhere on the body surface, including sensitive areas, for both adults and children as young as two years old,” said Jonathan Silverberg, MD, PhD, MPH, Professor of Dermatology at The George Washington University School of Medicine and Health Sciences in Washington, DC., and the Director of Clinical Research and Contact Dermatitis.

Dermavant recently released highly favorable results from a pediatric maximal usage pharmacokinetics (MUPK) study of VTAMA in AD. The study demonstrated minimal-to-no systemic exposure despite maximal use in subjects with extensive AD. 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 the FDA approved VTAMA® (tapinarof) cream, 1% for the treatment of adult plaque psoriasis. The approval made VTAMA the first non-steroidal topical novel chemical entity launched for psoriasis in the U.S. in more than 25 years. VTAMA is approved for mild, moderate, and severe plaque psoriasis - with no label safety warnings or precautions, restrictions on duration of use or body surface area. On July 15, 2022, VTAMA became the #1 prescribed branded topical treatment for plaque psoriasisⁱ in adults and to date has over 145,000 prescriptions written with over 10,000 unique prescribers^†.

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

ADORING is Dermavant’s pivotal Phase 3 atopic dermatitis (AD) clinical program for VTAMA® (tapinarof) cream, 1%, which consists of ADORING 1 (NCT05014568) and ADORING 2 (NCT05032859), as well as ADORING 3 (NCT05142774), a 48-week open-label, long-term extension study.

About Atopic Dermatitis

Atopic dermatitis (AD), commonly referred to as eczema, is one of the most common inflammatory skin diseases, affecting over 26 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.
