In a regulatory filing, Dianthus Therapeutics reported more data from Part A of its Phase 3 CAPTIVTY study evaluating claseprubart in chronic inflammatory demyelinating polyneuropathy. The company said that claseprubart is "highly potent" classical pathway inhibitor with a roughly 8-week half-life, with clinical and in vitro head-to-head data supporting its potential for a more effective and convenient biologic with no boxed warning. Dianthus said it observed a 75% response rate from the first 40 participants to complete CAPTIVATE Part A, supporting best-in-disease potential, which is higher than the overall rate in the riliprubart Phase 2 at week 24. The company added that mean INCAT score change in responders was at -1.6 at last evaluable visit, and that claseprubart has consistently higher affinity and stronger potency in multiple head-to-head in vitro experiments.

About DNTH
Dianthus Therapeutics, Inc. is a clinical-stage biotechnology company focused on developing therapies for the treatment of severe autoimmune diseases. The Company's lead clinical-stage candidate, claseprubart, is a monoclonal antibody that is purposefully engineered with extended half-life, improved potency, and high selectivity for only the active C1s complement protein (C1s) - enabling less frequent and convenient self-administered subcutaneous (S.C.) injections suitable for a pre-filled pen. It is conducting three mid- to late-stage clinical trials with claseprubart in generalized Myasthenia Gravis (gMG), Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), and Multifocal Motor Neuropathy (MMN). The Company's second clinical-stage candidate, DNTH212, is an investigational, extended half-life bifunctional fusion protein targeting plasmacytoid dendritic cell BDCA2 to reduce Type 1 interferon production, while simultaneously inhibiting BAFF/APRIL to suppress B cell function.
