DURHAM, N.C., July 10, 2025 (GLOBE NEWSWIRE) -- Pelthos Therapeutics Inc. (NYSE American: PTHS), a biopharmaceutical company committed to commercializing innovative therapeutic products for high unmet patient needs, today announced the launch of ZELSUVMI™ (berdazimer) topical gel, 10.3%, for the treatment of molluscum contagiosum (molluscum) in adults and pediatric patients one year of age and older.ⁱ^,ⁱⁱ ZELSUVMI received a Novel Drug designation from the U.S. Food and Drug Administration in January 2024 and is the first and only prescription therapy approved for use at home by patients, parents, and caregivers to treat molluscum infections, a highly contagious viral skin condition.

“We believe that the commercial launch of ZELSUVMI marks a significant advancement for patients with molluscum and their caregivers, who previously lacked an at-home treatment option for this burdensome skin infection,” said Scott Plesha, CEO of Pelthos. “We are excited to make ZELSUVMI widely available for the millions of patients afflicted by this condition. Our commercial efforts will aim to provide stellar education and support for patients seeking effective treatment for their molluscum infections.”

ZELSUVMI is a novel, topical nitric oxide-releasing gel for the treatment of molluscum at the time of diagnosis. The once-daily prescription medication is effective, well tolerated, and convenient for at-home or on-the-go application and can be used to treat infections on the body, including sensitive areas such as the face, groin, or underarms. ZELSUVMI was studied in the largest randomized clinical trial for the treatment of molluscum. The trial was a multicenter, randomized, double-blind, vehicle controlled, parallel-group, Phase 3 study of the efficacy and safety of ZELSUVMI in 891 patients. Complete clearance of molluscum lesions was seen in nearly 33% of patients compared with 19.7% of patients who did not receive the active ingredient at the twelfth week. For many patients, ZELSUVMI demonstrated results within two weeks.ⁱ^,ⁱⁱ

"Many parents delay seeking treatment for their children's uncomfortable lesions because current procedural treatments and frequent office visits can be inconvenient, while therapeutic options are limited. Untreated molluscum can spread throughout the child’s body but also to other family members," said Nanette Silverberg, MD, Chief of Pediatric Dermatology at the Mount Sinai Health System. “A safe and effective topical gel for molluscum, like ZELSUVMI, which can be applied at home or on the go, would make a significant difference for this young patient population and address a serious, unmet medical need."

"We are launching our ZelsuvmiGo patient support program, which we expect to help onboard patients seamlessly and provide resources for caregivers," said Sai Rangarao, Chief Commercial Officer at Pelthos. "To ensure that ZELSUVMI reaches the people who need it quickly, we have hired 50 sales territory managers across the country to work with physicians who treat a high volume of patients with molluscum. We have also implemented extensive digital outreach and awareness efforts to ensure ZELSUVMI can be prescribed by any healthcare provider at any time. These patients have waited a long time for an at-home treatment option."

ZELSUVMI is now commercially available through retail pharmacies, ASPN pharmacy services and for at-home delivery through mail-order pharmacies via prescription. For more information about ZELSUVMI visit zelsuvmi.com.

About Molluscum Contagiosum
Molluscum is a poxvirus and one of the most common skin infections seen by dermatologists, pediatric dermatologists, and pediatricians.

Molluscum infections present with raised, flesh-colored or red bumps that can appear anywhere on the body, including the face, hands, trunk, genitals, back of the knees, armpits, and other sensitive areas. People with molluscum may suffer discomfort from itching, secondary bacterial infections from scratching, or atopic dermatitis, as well as immense social stigma from having visible molluscum lesions that may persist for months to years. It is estimated that 30% of children will have lesions that persist beyond 18 months.^v Up to 73% of children with molluscum go untreated.^vi
