DNTH Dianthus Therapeutics Inc

Dianthus Therapeutics, Inc. (Nasdaq: DNTH), a clinical-stage biotechnology company dedicated to advancing the next generation of antibody complement therapeutics to treat severe autoimmune diseases, today announced the appointment of John C. King as Chief Commercial Officer. Mr. King brings more than 25 years of global commercial leadership experience within biotechnology, including complement inhibitor experience in neuromuscular and hematological rare diseases. In this newly created position, Mr. King will play a critical role in the Company’s corporate and commercial strategy.

“I’m excited to welcome John to the Dianthus executive team and I look forward to partnering with him as we move DNTH103 forward across three neuromuscular indications and prepare for our first top-line data in 2H’25 from our Phase 2 clinical trial in gMG,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “John is a strong, strategic leader who played a key role in establishing the foundation for the blockbuster gMG market and the multi-billion dollar C5 complement inhibitor franchise at Alexion, which continues to grow as first-line gMG therapy today. John then took on the role of CCO of Ra Pharma as it was developing the first FDA-approved, self-administered, subcutaneous biologic for the gMG market, leading to Ra Pharma’s acquisition by UCB for $2.5 billion. This wealth of experience will be highly valued at Dianthus as we continue to build an exciting late-stage biotech company.”

“I strongly believe DNTH103 has the potential to be a highly differentiated, first-line therapy and provide meaningful benefits for patients suffering from classical pathway-driven diseases, including gMG, CIDP and MMN. DNTH103’s best-in-class target profile would provide a unique combination of potency, safety and convenience with a patient-friendly, infrequent, self-administered subcutaneous auto-injector,” said John C. King, Chief Commercial Officer of Dianthus Therapeutics. “This is a transformational time for Dianthus and I’m thrilled to join the executive team ahead of key data readouts starting with gMG later this year.”

Mr. King started his biotech career at Wyeth Pharmaceuticals working on Enbrel® before he joined Alexion Pharmaceuticals, where he was Vice President, U.S. Neurology Business Unit responsible for building and leading the commercial team and strategy that launched Soliris® (eculizumab) into the generalized Myasthenia Gravis market as the first approved biologic and complement inhibitor. At Alexion, he also served as Vice President, Head of Global Hematology Franchise, among other leadership roles. Mr. King then joined Ra Pharma as the Chief Commercial Officer where he played a crucial role as part of the executive team in developing the commercial strategy for its C5 complement inhibitor in gMG and in its acquisition by UCB for $2.5 billion. Most recently, he was the Chief Commercial Officer at Vor Bio where he led commercial planning and business development for engineered cell therapies for patients with blood cancer. Mr. King began his career at Ernst & Young LLP and holds a Bachelor of Science in Business Logistics and a Master of Business Administration from Pennsylvania State University.

In addition, Sujay Kango has joined the Company’s Board of Directors. Mr. Kango is an experienced executive with more than 26 years of experience in the pharmaceutical and biotechnology sector. His vast, results-oriented experience ranges from serving as both public and private company board member to being a C-suite executive of multi-billion dollar public companies. He previously served on the boards of MEI Pharma and Infinity Pharmaceuticals, and currently serves as a board member of Adanate, Inc. Mr. Kango was the President and Chief Executive Officer of Tmunity Therapeutics, a clinical stage research and development CAR-T therapy company that was acquired by Gilead Sciences in February 2023 for an undisclosed amount. From 2018-2021, he served as the EVP, Chief Commercial Officer of Acceleron Pharma, which was acquired by Merck & Co. for over $11.5 billion. Mr. Kango has been responsible for over 5 blockbuster products and launches, including Reblozyl, Nexavar, Kyprolis, Peg-Intron, and Remicade. He earned a B.S. in Microbiology and an M.B.A. from McNeese State University.
