NEW YORK and WALTHAM, Mass., March 11, 2025 (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 fourth quarter and full year ending December 31, 2024 and provided an update on recent business achievements.
“We remain on track to report top-line data in 2H’25 from our Phase 2 clinical trial of DNTH103 in gMG, an indication where a best-in-class, potent active C1s and classical pathway inhibitor with the potential for effective and consistent symptom control along with improved safety and convenience could meaningfully advance the standard of care,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We are excited to have initiated our pivotal Phase 3 CAPTIVATE trial in CIDP, which is on track for an interim responder analysis in 2H’26, along with top-line results from our Phase 2 trial in MMN.”
DNTH103 Clinical Development
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.
Generalized Myasthenia Gravis (gMG)
- Phase 2 MaGic gMG trial ongoing: The MaGic trial is a global, randomized, double-blind, placebo-controlled Phase 2 trial in patients with gMG who are acetylcholine receptor (AChR) antibody positive, and it remains on track to report top-line results in 2H’25.
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
- Phase 3 CAPTIVATE CIDP trial ongoing: The CAPTIVATE trial is a single, global, two-part, randomized withdrawal Phase 3 trial in patients with CIDP, and it remains on track for an interim responder analysis in 2H’26. The Company believes this single pivotal trial will support a BLA filing in adult patients with CIDP.
Multifocal Motor Neuropathy (MMN)
- Phase 2 MoMeNtum MMN trial ongoing: The MoMeNtum trial is a global, randomized, double-blind, placebo-controlled Phase 2 trial in patients with MMN, and it remains on track to report top-line results in 2H’26.
Corporate Updates
- On March 5, 2025, John C. King was announced as Chief Commercial Officer and Sujay Kango joined the Company’s Board of Directors. Mr. King brings to Dianthus more than 25 years of global commercial leadership experience in biotechnology, including neuromuscular and hematological rare diseases. Mr. Kango is an experienced executive with more than 26 years of experience in the pharmaceutical and biotechnology sector.
Full Year 2024 Financial Results
- Cash Position – $357.0 million of cash, cash equivalents and investments as of December 31, 2024 is projected to provide runway into the second half of 2027.
- R&D Expenses – Research and development (R&D) expenses for the year ended December 31, 2024 were $83.1 million, inclusive of $5.6 million of stock-based compensation, compared to $32.8 million for the year ended December 31, 2023, which included $0.9 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 2 and Phase 3 development.
- G&A Expenses – General and administrative (G&A) expenses for the year ended December 31, 2024 totaled $25.0 million, inclusive of stock-based compensation of $7.3 million, compared to $18.2 million for the year ended December 31, 2023, which included $2.0 million of stock-based compensation. This increase in G&A expenses was primarily due to increased headcount and higher professional services costs.
- Net Loss – Net loss for the year ended December 31, 2024 was $85.0 million or $2.55 per share (basic and diluted) compared to $43.6 million or $8.45 per share (basic and diluted) for the year ended December 31, 2023.
- Additional Information – For additional information on the Company’s financial results for the year ended December 31, 2024, please refer to the Form 10-K filed with the SEC.
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 is building a neuromuscular franchise with DNTH103 and anticipates reporting top-line data from the Phase 2 MaGic trial in generalized Myasthenia Gravis in 2H’25, the interim responder analysis of the Phase 3 CAPITIVATE trial in Chronic Inflammatory Demyelinating Polyneuropathy in 2H’26, and top-line data from the Phase 2 MoMeNtum trial in Multifocal Motor Neuropathy in 2H’26.
DNTH103 is an investigational agent that is not approved as a therapy in any indication in any jurisdiction worldwide.
