Update on FDA Review of VTAMA^® (tapinarof) Cream, 1% for the Treatment of Atopic Dermatitis in Adults and Children 2 Years of Age and Older

JERSEY CITY, N.J., November 5, 2024 - Organon (NYSE: OGN), a global healthcare company with a mission to improve the health of women throughout their lives, today announced that the U.S. Food and Drug Administration (FDA) extended by three months the target action date of its review of the supplemental New Drug Application (sNDA) for VTAMA^® (tapinarof) cream, 1% as a treatment for atopic dermatitis (AD) in adults and children two years of age and older. The new target date is March 12, 2025, revised from the original target action date of December 12, 2024. The FDA has not raised any concerns regarding the safety and efficacy of VTAMA nor have they raised any concerns regarding the approvability of this indication.

As part of its review process, the FDA requested the final datasets and clinical study report from the long-term extension study for VTAMA. After receiving the datasets, the FDA determined that the additional information requested constitutes a major amendment to the sNDA resulting in a standard three-month extension to the original target action date.

"Organon remains confident in the robust efficacy and safety data package that has been submitted to the agency to support the review of VTAMA for atopic dermatitis and we are committed to working with the FDA ensure the agency has all the information it needs for its review," said Juan Camilo Arjona Ferreira, MD, Head of Research & Development at Organon.

With an assumed PDUFA date of March 12, 2025, the company expects that revenue contribution for VTAMA for the full year 2025 will be approximately $125 million and that the transaction will result in an approximate 75 basis point headwind to Adjusted EBITDA margin in 2025. This is an update to the company's prior commentary, provided during its third quarter earnings call held on October 31, 2024. The company will provide a more detailed outlook for 2025 expected consolidated financial performance, including revenue growth and expense optimization plans, in February 2025 when it reports full year 2024 results.

About Atopic Dermatitis

Atopic dermatitis (AD), commonly referred to as eczema, is one of the most common inflammatory skin diseases, affects 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 20% 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.
