Pelthos plans to launch ZELSUVMI™ for the treatment of Molluscum contagiosum infections in July 2025 Concurrent with the closing of the merger, Ligand has invested $18 million in the combined company and is entitled to a 13% royalty on worldwide sales of ZELSUVMI Pelthos will commence trading on the NYSE American exchange under the new ticker symbol “PTHS” on July 2, 2025 JUPITER, Fla., July 02, 2025 (GLOBE NEWSWIRE) -- Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) today announced the completion of its previously announced merger between the company’s wholly owned subsidiary, LNHC, Inc., and CHRO Merger Sub Inc., a wholly owned subsidiary of Channel Therapeutics Corporation (“Channel”). The combined company will operate under the name Pelthos Therapeutics Inc. (“Pelthos”) and will commence trading on the NYSE American exchange under the new ticker symbol “PTHS” on July 2, 2025. “Today marks not just a corporate milestone, but a transformative turning point for the team at Pelthos,” said Todd Davis, CEO of Ligand. “With the successful closing of this merger and the launch of Pelthos as an independent, publicly traded biopharmaceutical company, we have unlocked new potential for innovation and long-term value creation for our shareholders. This moment is the result of the vision, hard work, and unwavering commitment of our internal team, who developed the commercial platform to help bring ZELSUVMI, a novel product addressing a significant unmet need, to market this summer. Ligand recognized the potential value of ZELSUVMI before it was approved, during a time when others did not, and we are proud to bring this impactful treatment to market through our special situations initiatives.” Concurrent with the merger, Pelthos raised $50.1 million of equity capital, including a private placement from a group of strategic investors led by Murchinson (“Investor Group” and together with Ligand, the “Investors”). The Investor Group invested $32 million and Ligand invested $18 million in the combined company, respectively. The capital is being invested into Pelthos’ Series A Convertible Preferred Stock (“Series A”) and Common Stock and includes cancellation of approximately $18.8 million in bridge capital that was advanced to Pelthos by several of the Investors (including Ligand) since the beginning of 2025 to support the commercial launch of ZELSUVMI. Ligand is entitled to a 13% royalty on worldwide net sales of ZELSUVMI. “Ligand has been an incredible partner over the past few years, and we look forward to their continued guidance and support as members of the Pelthos board,” commented Scott Plesha, CEO of Pelthos. “We are excited to begin this new chapter as a publicly traded company and to bring this innovative product to the patients who need it.” Pelthos will initially focus on the launch and commercialization of ZELSUVMI (berdazimer) topical gel, 10.3%, for the treatment of Molluscum contagiosum infections (“molluscum”) in adults and pediatric patients one year of age and older.1 ZELSUVMI is an FDA-designated novel drug and the first and only prescription medication approved for the treatment of molluscum that can be administered at home by parents, patients, and caregivers. Molluscum is a poxvirus and one of the most common skin infections seen by dermatologists, pediatric dermatologists, and pediatricians, afflicting an estimated 16.7 million people in the United States.2,3 Additionally, Pelthos is continuing to evaluate the path forward for Channel’s existing NaV 1.7 development programs for the treatment of various types of chronic pain, acute and chronic eye pain, and post-surgical nerve blocks.
