Chemically, tapinarof is 3, 5-dihydroxy-4-isopropyl- trans -stilbene, also known as (E)-2-isopropyl-5-styrylbenzene-1,3-diol, with the empirical formula C 17 H 18 O 2 , a molecular weight of 254.32, and the following structural formula. Each gram of VTAMA cream for topical use contains 10 mg of tapinarof in a white to off-white cream. VTAMA cream also contains the following inactive ingredients: benzoic acid, butylated hydroxytoluene, citric acid monohydrate, diethylene glycol monoethyl ether, edetate disodium, emulsifying wax, medium-chain triglycerides, polyoxyl 2 stearyl ether, polyoxyl 20 stearyl ether, polysorbate 80, propylene glycol, purified water, and sodium citrate dihydrate. figure1

REACTIONS In plaque psoriasis, the most common adverse reactions (incidence ≥ 1%) were folliculitis, nasopharyngitis, contact dermatitis, headache, pruritus, and influenza. ( 6.1 ) In atopic dermatitis, the most common adverse reactions (incidence ≥ 1%) were upper respiratory tract infection, folliculitis, lower respiratory tract infection, headache, asthma, vomiting, ear infection, pain in extremity, and abdominal pain.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Plaque Psoriasis Clinical

Trials In two randomized, double-blind, multicenter, vehicle-controlled clinical trials (PSOARING 1 and PSOARING 2), 1025 adults with plaque psoriasis were treated with VTAMA cream or received vehicle cream once daily for up to 12 weeks. Subjects ranged in age from 18 to 75 years, with an overall median age of 51 years. The majority of subjects were White (85%) and male (57%); and 85% identified as non-Hispanic or Latino.

1 presents adverse reactions that occurred in at least 1% of subjects treated with VTAMA cream, and for which the rate exceeded the rate for vehicle.

Adverse reactions leading to treatment discontinuation in >1% of subjects who received VTAMA cream were contact dermatitis (2.9%) and folliculitis (2.8%). In an open label safety trial (PSOARING 3), 763 subjects were treated for up to an additional 40 weeks after completing PSOARING 1 or PSOARING 2. In addition to the adverse reactions reported in the 12-week PSOARING 1 and PSOARING 2 clinical trials, the following adverse reactions were reported: urticaria (1.0%) and drug eruption (0.7%).

Atopic Dermatitis Clinical

Trials In two randomized, double-blind, multicenter, vehicle-controlled clinical trials (ADORING 1 and ADORING 2), 811 adult and pediatric subjects 2 years of age and older with atopic dermatitis were treated with VTAMA cream or received vehicle cream once daily for up to 8 weeks. Subjects ranged in age from 2 to 81 years, with an overall median age of 11 years. The majority (51%) of subjects were White, 31% were Black, 12% were Asian; 54% were female; and 78% of subjects identified as non-Hispanic or Latino.

The adverse reactions observed in pediatric subjects 2 years of age and older were generally consistent with those observed in adults with atopic dermatitis. Adverse reactions occurring more frequently in pediatric subjects compared to adults were upper respiratory tract infection (16.3% in subjects ages 2-6 years of age and 11.2% in subjects ages 7-17 years of age vs. 9.5% in subjects 18 years and older) and ear infection (5.7% in subjects ages 2-6 years of age and 1.4% in subjects ages 7-11 years of age vs. 0% in subjects 12 years and older). In an open label safety trial (ADORING 3), 728 subjects (124 adult and 604 pediatric subjects 2 years of age and older) were treated for up to 48 weeks. This included 624 subjects completing either ADORING 1 or ADORING 2, 28 subjects completing the maximal usage trial, and 76 subjects treated only in ADORING 3. The safety profile with long term use was generally consistent with the safety profile observed at Week 8.
