·9 min read

- EFFICACY: In the pivotal Phase 3 clinical trial program, VTAMA cream met all primary and secondary endpoints and demonstrated highly statistically significant improvement versus vehicle in Physician Global Assessment (PGA) score with 36% of patients versus 6% in vehicle in PSOARING 1 and 40% of patients versus 6% in vehicle in PSOARING 2 achieving clear or almost clear with a minimum 2-grade improvement at week 12 (p<0.0001 for both trials) -

- REMITTIVE EFFECT: The median duration of clear or almost clear skin was approximately four months after cessation of treatment with VTAMA cream as measured by the time to first worsening while off-therapy during the Phase 3 Long Term Extension (LTE) study for patients who achieved clear skin (PGA 0) on VTAMA cream during PSOARING 1 or 2 -

- DURABILITY: Durability of response up to 52 weeks was demonstrated with intermittent use of VTAMA cream, with no observation of tachyphylaxis (loss of response) while on therapy -

- SAFE AND WELL-TOLERATED, EVEN ON SENSITIVE SKIN AREAS: The safety profile and favorable tolerability of VTAMA cream reported was consistent across PSOARING 1, PSOARING 2 and the Phase 3 LTE, with the majority of adverse events (AEs) localized to site of application, and mild to moderate in nature -

- PATIENT OBSERVATIONS: Patient satisfaction data from the Phase 3 LTE study demonstrated a consistent and positive perception of VTAMA cream across many measures, with 81.7% considering it more effective than prior topical treatments -

- Approved for mild, moderate, and severe psoriasis with no restrictions on duration of use or body surface and remittive effect on-label. Dermavant is prepared for a June 2022 launch with product and sample manufacturing runs completed and a fully staffed commercial team.

"We are delighted with our FDA-approved label for VTAMA cream, which is for adults with psoriasis, regardless of disease severity, and with an unlimited duration of use. In anticipation of today’s approval, we have a fully built commercial infrastructure in place, and I am excited to say we will have product in the channel in the first week of June. As the first and only approved drug in its class in the U.S., the FDA’s approval of VTAMA cream provides an effective new non-steroidal treatment option for millions of adults living with plaque psoriasis and represents a major milestone for Dermavant and its stakeholders," said Todd Zavodnick, Chief Executive Officer of Dermavant. "At Dermavant, we are committed to advancing novel, patient-focused innovation in immuno-dermatology. As such, we are proud to have developed a topical treatment in VTAMA cream that provides not only efficacy over 52 weeks but can also be used on all body areas, including on sensitive locations, such as face, skin folds, neck, genitalia, anal crux, inflammatory areas, and axillae. In addition, an approximately four month off-treatment remittive effect (median time to first worsening), leads us to believe that VTAMA cream has the potential to become the preferred topical option for this chronically underserved patient population and among the physicians who treat them."

"Following 20-plus years of minimal innovation in the topical psoriasis treatment space1,2,3,4, I believe the approval of VTAMA cream is an important step in establishing a new treatment option for adults with mild, moderate and severe plaque psoriasis5," said Mark Lebwohl, MD, FAAD, Dean for Clinical Therapeutics and Waldman Professor and Chairman Emeritus of the Kimberly and Eric J. Waldman Department of Dermatology, Icahn School of Medicine at Mount Sinai in New York and lead author of the Phase 3 studies of VTAMA cream published in The New England Journal of Medicine. "As a clinician, I’m excited to finally have a versatile, once-daily, steroid-free topical treatment that is backed by extensive clinical trial data supporting its favorable safety and efficacy profile and a demonstrated remittive effect of approximately four months in patients off therapy."

Across PSOARING 1 and PSOARING 2, VTAMA cream demonstrated highly statistically significant improvement in Physician Global Assessment (PGA)6 score of "clear" (PGA=0) or "almost clear" (PGA=1) with a minimum 2-grade improvement compared with vehicle from baseline at week 12. VTAMA cream also demonstrated a highly statistically significant improvement in all secondary endpoints versus vehicle, including ≥75% Improvement in Psoriasis Area and Severity Index (PASI) score (PASI-75) from baseline at week 127. The adverse event (AE) profile of VTAMA cream reported in both PSOARING 1 and PSOARING 2 demonstrated that the majority of AEs were localized to the site of application and were mild to moderate in nature. The most common AEs of subjects treated with VTAMA cream were folliculitis, nasopharyngitis, and contact dermatitis.

Eligible patients who completed PSOARING 1 or PSOARING 2 could enroll in PSOARING 3, a Phase 3 Long Term Extension (LTE) study, which consisted of an additional 40 weeks of open-label treatment with VTAMA cream, followed by a four-week follow-up. As such, patients who were randomized to VTAMA cream in PSOARING 1 or PSOARING 2 and who also completed the Phase 3 LTE study received VTAMA cream treatment for up to 52 weeks. 92% of patients who completed PSOARING 1 and PSOARING 2 enrolled in the Phase 3 LTE study.

Over 40% of Phase 3 LTE study patients (n=312/763) achieved complete disease clearance (PGA=0) at least once during the study period. For patients randomized to VTAMA cream in PSOARING 1 and PSOARING 2 who achieved a PGA of 0 during the 12-week study and subsequently enrolled in the Phase 3 LTE study (n=73), VTAMA cream demonstrated a remittive effect (maintenance of PGA of 0 or 1 while off therapy) with a median duration to first worsening of approximately four months. Among a larger cohort of patients who either entered the Phase 3 LTE study with a PGA score of 0 or achieved one during the LTE study (n=312), the mean duration of remittive effect off-therapy was 130 days.

In the Phase 3 LTE study, VTAMA cream demonstrated safety and tolerability consistent with PSOARING 1 and PSOARING 2. Treatment emergent adverse events were mostly mild to moderate in nature and restricted to application sites.

Responses to a questionnaire, which were assessed at Phase 3 LTE study completion (week 40 or early termination), demonstrated consistent high rates of satisfaction across all evaluated parameters. Of the 78.5% (n=599) of patients from Phase 3 LTE study who completed the survey: 85.8% of patients felt they could easily manage their psoriasis with VTAMA cream; 83.6% were satisfied with how well VTAMA cream worked; 81.7% considered it more effective than prior topical treatments, and most patients strongly agreed or agreed VTAMA cream absorbed quickly (89.5%), was not greasy (89.0%), and felt good on their skin (79.9%).

"We believe VTAMA cream has the potential to make a meaningful difference in the lives of patients with plaque psoriasis as well as their healthcare providers," said Philip M. Brown, M.D., J.D., Chief Medical Officer of Dermavant. "We are continuing to leverage our experience and insights with the active ingredient, tapinarof, and potentially other AhR molecules, for potential application to other conditions in dermatology and additional inflammatory and immunology indications."

In September 2021, Dermavant Sciences announced that it dosed its first patient in a Phase 3, double-blind, vehicle-controlled study of tapinarof cream for the treatment of atopic dermatitis (AD) in adults and children. The Phase 3 clinical program will enroll up to 800 patients across two pivotal trials (ADORING 1 and ADORING 2) to evaluate the safety and efficacy of tapinarof 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 company anticipates announcing topline results from ADORING 1 and ADORING 2 in 1H 2023.

About Psoriasis

Impacting approximately 8 million Americans and 125 million people worldwide, psoriasis is a complex autoimmune disease — meaning that the body’s immune system targets and attacks its own cells. Plaque psoriasis, also called psoriasis vulgaris, is the most common form and affects about 80 to 90% of people with psoriasis. In people with light skin, plaque psoriasis is characterized by raised, red or pink patches of skin with silvery-white scale. People with black or brown skin are more likely to have brown or violet-colored patches with silvery-white or gray scale. The scale can be itchy, painful and disfiguring.

Psoriasis can begin at any age, but typically appears around 15 to 25 years of age. The exact cause of psoriasis is not known, but risk factors and triggers may include genetics or a family history of psoriasis, as well as stress, smoking, heavy alcohol consumption and cold or dry weather conditions. People with psoriasis are at an increased risk of developing other health conditions, including psoriatic arthritis, inflammatory bowel disease, hypertension, diabetes, obesity, and depression. In addition to physical symptoms, psoriasis can have a significant impact on a person’s quality of life and psychological health.
