Dianthus Therapeutics Announces Oral Presentation for DNTH103 at the 2024 American Academy of Neurology (AAN) Annual Meeting

April 11, 2024 at 7:30 AM EDT

NEW YORK and WALTHAM, Mass., April 11, 2024 (GLOBE NEWSWIRE) -- 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 an oral presentation for DNTH103 at the American Academy of Neurology (AAN) Annual Meeting, taking place April 13-18, 2024 in Denver, Colorado and virtually.

DNTH103 is an investigational classical pathway inhibitor that is uniquely specific to the active form of C1s, and is being evaluated for its potential as an effective, low-volume, convenient and safe treatment option for patients with generalized Myasthenia Gravis, Multifocal Motor Neuropathy, and Chronic Inflammatory Demyelinating Polyneuropathy. The oral presentation at AAN will highlight preclinical and in vitro data describing the differentiated safety profile and neurotransmission activity of DNTH103 and a review of previously released Phase 1 healthy volunteer data.

“Currently, therapies for patients with generalized Myasthenia Gravis (gMG) are limited to C5 inhibitors or FcRn inhibitors that can be burdensome for patients and caregivers, and the C5 complement inhibitors available today have an increased risk for serious bacterial infections,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We aim to demonstrate that DNTH103 may be a best-in-class treatment option with improved safety and infrequent self-administration that provides effective and consistent control of symptoms for people living with neuromuscular conditions.”

Oral Presentation Details:
April 15, 2024, 1:00 PM MT / 3:00 PM ET
Classical Pathway Inhibition with Anti-Active C1s Antibody DNTH103 Prevents Neurotransmission Impairment in a Preclinical Model of Myasthenia Gravis

About DNTH103
DNTH103 is an investigational, clinical-stage, potent monoclonal antibody engineered to selectively target the classical pathway by inhibiting only the active form of the C1s protein, a clinically validated complement target. DNTH103 is enhanced with YTE half-life extension technology designed to enable a more convenient subcutaneous, self-administered injection dosed as infrequently as once every two weeks. Additionally, selective inhibition of the classical complement pathway may lower patient risk of infection from encapsulated bacteria by preserving immune activity of the lectin and alternative pathways. As the classical pathway plays a significant role in disease pathology, DNTH103 has the potential to be a best-in-class pipeline-in-a-product across a range of autoimmune disorders with high unmet need. Dianthus has initiated a Phase 2 trial in generalized Myasthenia Gravis and plans to initiate additional Phase 2 trials in other neuromuscular indications, including Multifocal Motor Neuropathy and Chronic Inflammatory Demyelinating Polyneuropathy, in 2024.
