JUPITER, Fla., July 10, 2025 (GLOBE NEWSWIRE) — Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) today announced that its partner Pelthos Therapeutics Inc. (NYSE American: PTHS) has commercially launched ZELSUVMI™ (berdazimer) topical gel 10.3%, the first and only FDA-approved at-home treatment for molluscum contagiosum. The Company has earned a $5 million milestone payment from Pelthos following the commercial launch of ZELSUVMI.

“Molluscum impacts millions of people in the U.S., particularly children. We are thrilled to see that ZELSUVMI is now commercially available as it addresses a significant unmet need for these patients as the first at-home treatment for this highly contagious viral skin condition,” said Todd Davis, CEO of Ligand. “This milestone payment highlights the ongoing progress and significant value of our partnered programs as well as the strength of our business model, which is built on innovation, strategic collaboration, and long-term value creation for our shareholders.”

Following the completion of the merger between Pelthos Therapeutics and Channel Therapeutics in July 2025, Ligand now owns 56% of Pelthos. Additionally, under the terms of the license agreement with Pelthos, Ligand is entitled to a 13% royalty on worldwide sales of ZELSUVMI and up to an additional $5 million in commercial sales milestones.
