About Us

Dianthus Therapeutics is a clinical-stage biotechnology company dedicated to designing and delivering novel, best-in-class monoclonal antibodies with improved selectivity and potency over existing complement therapies. Based in New York City and Waltham, Mass. Dianthus is comprised of an experienced team of biotech and pharma executives who are leading the next generation of antibody complement therapeutics to deliver transformative medicines for patients with severe autoimmune diseases.

Since raising a $100M Series A in April 2022 co-led by 5AM Ventures, Avidity Partners, and Fidelity Management & Research Company, with participation from additional investors including Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures, and Venrock Healthcare Capital Partners, Dianthus continues to make progress in advancing its lead monoclonal antibody, DNTH103.

On May 3rd, 2023, Dianthus announced it entered into a reverse merger transaction with Magenta Therapeutics, a publicly traded biotech company, to create a new public company with the sole focus on advancing Dianthus’ pipeline of next generation complement therapies. In support of the merger, Dianthus has secured commitments for a $70 million private investment in its common stock and pre-funded warrants from a syndicate of healthcare investors led by Fidelity Management & Research Company, Catalio Capital Management, 5AM Ventures, Avidity Partners, Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures and Venrock Healthcare Capital Partners, that is expected to close immediately prior to completion of the merger. With the cash expected from both companies at closing and the proceeds of the concurrent private financing, the combined company is expected to have approximately $180 million of cash or cash equivalents immediately post-closing.

Dianthus has a steady cadence of milestones with DNTH103 including top line Phase 1 data aiming to confirm potent classical pathway inhibition and favorable, extended PK expected by the end of 2023, initiation of planned Phase 2 trial in generalized Myasthenia Gravis expected in Q1 2024 followed by two additional planned Phase 2 trial initiations in other neuro indications, and planned initiation of an open label proof of efficacy trial in Cold Agglutinin Disease with patient data expected in 2H 2024.
