Magenta Therapeutics and Dianthus Therapeutics Announce Merger Agreement - Seite 2

“I’m delighted to announce this planned merger with Magenta, which comes at a pivotal moment in the evolution of our company as we advance our pipeline of next-generation complement therapeutics for people living with severe autoimmune diseases,” said Marino Garcia, President and Chief Executive Officer of Dianthus Therapeutics. “Gaining access to the public capital markets can enhance our financial strength and fuel our growth strategy, enabling us to unlock the full potential of our pipeline, including our plans to address multiple autoimmune disorders with our clinical-stage active C1s inhibitor, DNTH103.”

“After a thorough exploration of our strategic alternatives, management and our Board of Directors believe the transaction with Dianthus Therapeutics will culminate in a successful outcome for our stockholders,” said Steve Mahoney, President, Chief Financial and Operating Officer of Magenta. “Dianthus has made rapid progress in developing and advancing DNTH103 into the clinic where it has the potential to be a transformative classical pathway inhibitor for severe autoimmune diseases. We are extremely grateful to our current and former employees who contributed to Magenta’s efforts to develop its programs and we now look forward to the combined company’s advancement on opportunities for value creation for patients.”

Magenta previously announced a comprehensive review of strategic alternatives in February 2023 and has since completed winding down a majority of its activities and costs associated with its research and development initiatives, including the termination of its lease and the sale of key assets.

About DNTH103
DNTH103 is an investigational long-acting classical complement pathway inhibitor designed as a less frequent and convenient subcutaneous injection with the potential to treat people living with severe autoimmune diseases. DNTH103, a fully human monoclonal antibody, is designed to selectively target only the active form of the C1s complement protein, inhibiting only the classical complement pathway, with the aim of treating patients with a lower dosing volume as a convenient subcutaneous injection suitable for a self-administered pre-filled pen. Inhibiting the active form of the complement target seeks to address a critical treatment gap in current complement therapies that do not bind selectively to the active protein, wasting a significant amount of the drug on inert proteins. DNTH103 selective inhibition of the classical pathway is engineered to preserve important immune activity of the lectin and alternative complement pathways needed to protect the body against infections from encapsulated bacteria. DNTH103 is also enhanced with YTE half-life extension technology to further reduce dosing frequency.
