Organon's VTAMA® (tapinarof) cream, 1%, Granted Strong Recommendation in the American Academy of Dermatology Updated 2025 Guidelines for Adult Atopic Dermatitis

• The American Academy of Dermatology (AAD) provides a strong evidence-based recommendation for the use of VTAMA cream in adults with moderate to severe atopic dermatitis (AD), the most common form of eczema.
• Recommendation reflects VTAMA cream's proven efficacy, safety, and tolerability as a steroid-free, topical aryl hydrocarbon receptor agonist.
• AD impacts 26 million people in the United States, 16.5 million of which are adults.

Organon (NYSE:OGN), a global independent healthcare company with a focus on women's health, today announced that VTAMA^® (tapinarof) cream, 1%, was granted a strong recommendation by the American Academy of Dermatology (AAD) in their 2025 focused guideline update for the management of adults with moderate to severe atopic dermatitis (AD). The recommendation underscores VTAMA cream as an effective, steroid-free option for daily disease management, with no label warnings or precautions, no contraindications, and no restrictions on duration of use or percentage of body surface area affected. In AD, 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.

"With 6.6 million adults in the US living with moderate to severe AD, innovative treatment options that meet the highest standards for efficacy, safety, and tolerability are necessary to help provide lasting relief. We are proud of the AAD's strong evidence-based recommendation from the ADORING 1 and ADORING 2 8-week clinical trials for VTAMA cream—a once daily, steroid-free topical with no label restrictions on use based on disease severity, percentage of body surface area affected, or duration of use," said Juan Camilo Arjona Ferreira, Head of Research and Development and Chief Medical Officer at Organon. "This strong recommendation, paired with the findings from our Phase 3 ADORING 3 48-week, open-label, long-term extension study which uncovered the possibility of a treatment-free interval lasting on average 80 days after treatment success, highlights how VTAMA cream has the potential to redefine the AD treatment landscape and provide lasting results."

The focused update incorporates topical and systemic therapies that have been recently approved by the US Food and Drug Administration (FDA) into the AAD's existing guidance on the management of AD in adults to ensure the dermatology community has access to the best available evidence.

In December 2024, the FDA approved VTAMA cream for the topical treatment of AD in adults and pediatric patients 2 years of age and older. VTAMA cream was also approved by the FDA on May 24, 2022, for the topical treatment of mild, moderate, and severe plaque psoriasis in adults.

• the topical treatment of plaque psoriasis in adults
• the topical treatment of atopic dermatitis in adults and pediatric patients 2 years of age and older
