Phase 2 MaGic trial in generalized Myasthenia Gravis (gMG) ongoing; top-line results anticipated in 2H’25 IND for Phase 2 MoMeNtum trial in Multifocal Motor Neuropathy (MMN) cleared by FDA in June; top-line results anticipated in 2H’26 Phase 2 trial in Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) to initiate 2H’24 Approximately $361 million of cash provides runway into 2H’27 NEW YORK and WALTHAM, Mass., Aug. 08, 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 reported financial results for the second quarter ending June 30, 2024, and provided an update on recent business achievements. “The second quarter of 2024 highlighted the Dianthus team’s continued focus on execution and operational excellence as we advance our clinical programs for DNTH103 in generalized Myasthenia Gravis, Multifocal Motor Neuropathy, and Chronic Inflammatory Demyelinating Polyneuropathy,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We believe DNTH103 may be a potentially best-in-class, potent classical complement pathway inhibitor with infrequent, subcutaneous self-administration and a differentiated safety profile across our three initial indications of gMG, MMN and CIDP. We continue to be confident in the pipeline-in-a-product potential of DNTH103 across multiple autoimmune diseases, supported by our proof-of-concept in vitro data presented at EAN and recent competitor clinical data that further validate targeting the classical pathway and active C1s.” Recent Business Highlights and Upcoming Milestones 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. DNTH103 has the potential to be a best-in-class pipeline-in-a-product across a range of autoimmune disorders with high unmet need. Phase 2 MaGic gMG trial ongoing: The MaGic trial is a global, randomized, double-blind, placebo-controlled Phase 2 study in patients with gMG who are acetylcholine receptor (AChR) antibody positive. Initial top-line results from this trial are anticipated to be available in the second half of 2025.Phase 2 IND cleared for MoMeNtum MMN trial: The MoMeNtum trial is a global, randomized, double-blind, placebo-controlled Phase 2 study designed to evaluate the safety, tolerability, and efficacy of DNTH103 in patients with MMN. Initial top-line results from this trial are anticipated to be available in the second half of 2026.One oral presentation highlighted DNTH103 at AAN 2024: An oral presentation at the American Academy of Neurology (AAN) Annual Meeting in Denver highlighted 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.Two DNTH103 posters presented at EAN 2024: Two poster presentations at the 10th Congress of the European Academy of Neurology (EAN) in Helsinki highlighted preclinical and in vitro data describing the potentially differentiated profile of DNTH103 in disease models of gMG and CIDP, in addition to head-to-head affinity and pharmacodynamic (PD) potency data for DNTH103 compared to riliprubart.Planning for CIDP Phase 2 trial ongoing: Dianthus remains on track to initiate a Phase 2 trial of DNTH103 in CIDP in the second half of 2024. Corporate Effective July 1, 2024, Alison Lawton was appointed Chair of the Dianthus Therapeutics Board of Directors. She succeeded Lonnie Moulder, who remains on the Board of Directors. Second-Quarter 2024 Financial Results Cash Position - $360.7 million of cash, cash equivalents and short-term investments as of June 30, 2024 is projected to provide runway into the second half of 2027.R&D Expenses - Research and development (R&D) expenses for the quarter ended June 30, 2024 were $18.1 million, inclusive of $1.4 million of stock-based compensation, compared to $10.3 million for the quarter ended June 30, 2023, which included $0.1 million of stock-based compensation. This increase in R&D expenses was primarily driven by higher clinical costs, chemistry, manufacturing and controls (CMC) costs and increased headcount to support DNTH103 Phase 1 and Phase 2 development.G&A Expenses - General and administrative (G&A) expenses for the quarter ended June 30, 2024 totaled $6.0 million, inclusive of stock-based compensation of $1.8 million, compared to $2.5 million for the quarter ended June 30, 2023, which included $0.3 million of stock-based compensation. This increase in G&A expenses was primarily due to higher headcount and consulting and professional fees.Net Loss - Net loss for the quarter ended June 30, 2024 was $17.6 million or $0.51 per share (basic and diluted) compared to $11.1 million or $12.73 per share (basic and diluted) for the quarter ended June 30, 2023. About DNTH103DNTH103 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 is building a neuromuscular franchise with DNTH103 following the initiation of the Phase 2 MaGic trial in generalized Myasthenia Gravis in 1Q’24, regulatory clearance for Multifocal Motor Neuropathy in 2Q’24, and planned initiation of a Phase 2 trial in Chronic Inflammatory Demyelinating Polyneuropathy in 2H’24. DNTH103 is an investigational agent that is not approved as a therapy in any indication in any jurisdiction worldwide.
