DURHAM, N.C., July 02, 2025 (GLOBE NEWSWIRE) — Pelthos Therapeutics Inc., a biopharmaceutical company committed to commercializing innovative therapeutic products for high unmet patient needs, today announced the closing of the previously announced merger agreement pursuant to which CHRO Merger Sub Inc. (“Merger Sub”), a wholly owned subsidiary of Channel Therapeutics Corporation (“Channel”), merged with and into LNHC, Inc. (“LNHC”), a wholly owned subsidiary of Ligand Pharmaceuticals Incorporated (“Ligand”) (Nasdaq: LGND), with LNHC surviving as a wholly owned subsidiary of Channel (the “Merger”). The combined company will operate under the name Pelthos Therapeutics Inc. (“Pelthos” or the “Company”), and its shares will trade on the NYSE American exchange starting on July 2, 2025 under the new ticker symbol “PTHS”.

“This Merger represents a significant milestone for Pelthos, taking us closer to the launch of ZELSUVMI™ and enabling us to deliver this innovative product to the patients who need it. We are excited to begin this new chapter as a publicly traded company and to create value for our shareholders,” said Scott Plesha, the CEO of the Company following the Merger.

Concurrent with the Merger, Pelthos closed on a $50.1 million private placement from a group of strategic investors led by Murchinson Ltd. (“Investors”). The capital is being invested into Pelthos’ shares of Series A Convertible Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”) and common stock, par value $0.01, and includes cancellation of approximately $18.8 million in bridge capital that has been advanced to Pelthos by certain of the private placement Investors since the beginning of 2025 to support the commercial launch of ZELSUVMI™.

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 its 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.

Frank Knuettel II, former CEO of Channel Therapeutics Corporation and the newly appointed CFO of Pelthos, added, “I am pleased to have completed the Merger on behalf of Channel’s shareholders, and I am delighted to join the high-caliber team at Pelthos to help guide the launch of ZELSUVMI™. The management team has extensive experience in successfully launching new therapies, and I believe this transaction will position Pelthos for future growth.”

A.G.P. / Alliance Global Partners served as financial advisor to Channel. Sullivan & Worcester LLP served as Channel’s legal counsel and Latham & Watkins LLP served as lead counsel to Ligand. Kelley Drye & Warren LLP and Morgan, Lewis and Bockius LLP represented Murchinson Ltd.
