Organon Completes Acquisition of Dermavant, including Innovative Dermatologic Therapy, VTAMA ® (tapinarof) Cream, 1%

Organon (NYSE: OGN), a global healthcare company with a mission to improve the health of women throughout their lives, today announced the successful completion of its acquisition of Dermavant Sciences Ltd. from Roivant (NASDAQ: ROIV). Dermavant is a company dedicated to developing and commercializing innovative therapeutic solutions in immuno-dermatology. Please see our prior announcement for a summary of the transaction terms.

VTAMA^® (tapinarof) cream, 1%, is a novel nonbiologic, non-steroidal topical therapy approved by the U.S. Food and Drug Administration (FDA) for treatment of mild, moderate, and severe plaque psoriasis in adults with no safety label warnings or precautions and without restrictions on location and duration of use or body surface area. The FDA is reviewing a supplemental New Drug Application (sNDA) for VTAMA cream as a potential treatment for atopic dermatitis (AD) in adults and children two years of age and older, with Prescription Drug User Fee Act (PDUFA) action expected in the fourth quarter of calendar year 2024.

Plaque psoriasis and atopic dermatitis-commonly known as eczema-are common chronic inflammatory skin diseases affecting millions of people in the U.S. and around the globe.^1,2 Psoriasis presents a significant impact to quality of life and atopic dermatitis is associated with a higher disease burden for women compared to men.^3,4

“The future of dermatology depends on innovative treatments like VTAMA, and Organon’s acquisition of Dermavant allows us to further expand our existing portfolio of established brands and biosimilar dermatology treatments,” said Kevin Ali, Chief Executive Officer of Organon. “Integrating the expertise of Dermavant into Organon’s U.S. organization marks the beginning of a new chapter in dermatology. We are excited to bring this nonbiologic non-steroidal topical option to the millions of patients suffering from a chronic skin condition like plaque psoriasis and, potentially in the future, atopic dermatitis.”

“I would like to thank Kevin and the entire Organon team for their partnership in the acquisition of Dermavant,” said Mayukh Sukhatme, MD, President and Chief Investment Officer of Roivant. “This deal represents a true win-win outcome for Organon and Roivant in our mutual goal to address patient needs and is emblematic of Roivant’s ability to form non-traditional, value-enhancing collaborations on important medicines. We believe that Organon’s strong global commercial footprint will maximize the impact of VTAMA for patients globally, and we are excited to continue to share meaningfully in the success of VTAMA along the way.”
