Phase 2 MaGic trial in generalized Myasthenia Gravis (gMG) initiated in Q1’24 with top-line results anticipated in 2H’25 $389 million of pro forma cash, including $216 million of net proceeds from a successful PIPE financing completed in January 2024, provides runway into 2H 2027 Building a neuromuscular franchise with DNTH103 through additional planned Phase 2 trials in Multifocal Motor Neuropathy (MMN) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) starting in 2024 NEW YORK and WALTHAM, Mass., March 21, 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 fourth quarter and full year ending December 31, 2023, and provided an update on recent business achievements. “2023 was a transformative year for Dianthus, highlighted by becoming a public company, closing on a financing, and reporting out positive top-line data from our Phase 1 study that supports DNTH103 as a potentially best-in-class complement inhibitor,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “DNTH103 is an investigational potent active C1s inhibitor of the classical pathway with an extended half-life that has the potential to offer a more convenient, safer treatment option for patients with infrequent, subcutaneous self-administration. With our Phase 2 MaGic trial now underway in patients with generalized Myasthenia Gravis (gMG) and cash runway into the second half of 2027 following successful completion of a $230 million PIPE financing in January, we are very well positioned to build a neuromuscular franchise around DNTH103 and reach key data readouts in our three initial indications of gMG, Multifocal Motor Neuropathy (MMN) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).” 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 initiated in February: The MaGic trial is a global, randomized, double-blind, placebo-controlled Phase 2 study in up to 60 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. Oral presentation at the American Academy of Neurology (AAN) 2024 Annual Meeting on April 15, 2024: An oral presentation describing key attributes of DNTH103 and its differentiation in gMG will be presented by Sankalp Gokhale, M.D., Dianthus Therapeutics’ Head of Clinical Development, Neurology, at the AAN 2024 Annual Meeting, being held April 13-18, 2024, in Denver and online. (Program number S15.001) Planning for MMN and CIDP Phase 2 trials ongoing: Dianthus expects to initiate additional Phase 2 trials of DNTH103 in Multifocal Motor Neuropathy (MMN) in the second quarter of 2024 and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) in the second half of 2024. Corporate Dianthus successfully completed a private investment in public equity (“PIPE”) financing in January 2024 that resulted in gross proceeds of approximately $230 million. This PIPE financing included participation from both new and existing investors, including Bain Capital Life Sciences, RA Capital Management, Avidity Partners, Fairmount, Venrock Healthcare Capital Partners, RTW Investments, Great Point Partners LLC, Octagon Capital, Janus Henderson Investors, Vestal Point Capital, Logos Capital, Catalio Capital Management, Woodline Partners LP, Ally Bridge Group, Tellus BioVentures, StemPoint Capital LP and a large investment management firm. Jeffrey Stavenhagen, Ph.D., was appointed as Chief Scientific Officer in November 2023 to lead the Company’s discovery and preclinical research and translational science initiatives. Full-Year 2023 Financial Results Cash Position – $389 million of pro forma cash includes cash, cash equivalents and short-term investments as of December 31, 2023 of $173.7 million plus estimated net proceeds of approximately $216 million from the PIPE offering, which closed in January 2024. Net proceeds from the PIPE are unaudited and preliminary. R&D Expenses – Research and development (R&D) expenses for the year ended December 31, 2023 were $32.8 million, inclusive of $0.9 million of stock-based compensation, compared to $29.4 million for the year ended December 31, 2022, which included $0.4 million of stock-based compensation. This increase in R&D expenses was primarily driven by increased clinical costs and higher headcount to support DNTH103 Phase 1 and Phase 2 development partially offset by lower chemistry, manufacturing and controls (CMC) costs. G&A Expenses – General and administrative (G&A) expenses for the year ended December 31, 2023 were $18.2 million, inclusive of stock-based compensation of $2.0 million, compared to $6.7 million for the year ended December 31, 2022, which included $1.1 million of stock-based compensation. This increase in G&A expenses was primarily due to costs related to the reverse merger with Magenta and higher headcount and professional fees. Net Loss – Net loss for the year ended December 31, 2023 was $43.6 million or $8.45 net loss per share (basic and diluted) compared to $28.5 million or $32.57 net loss for the year ended December 31, 2022. Additional Information – For additional information on the Company’s financial results for the year ended December 31, 2023, 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 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.
