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.

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.

Initiation of a single, two-part, pivotal Phase 3 trial of DNTH103 in Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) anticipated by YE’24

Phase 2 MaGic trial of DNTH103 in generalized Myasthenia Gravis (gMG) ongoing;
top-line results anticipated in 2H’25

Phase 2 MoMeNtum trial of DNTH103 in Multifocal Motor Neuropathy (MMN) ongoing;
top-line results anticipated in 2H’26

Approximately $343 million of cash provides runway into 2H’27

NEW YORK and WALTHAM, Mass., Nov. 07, 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 third quarter ending September 30, 2024 and provided an update on recent business achievements.

“We are excited to expand DNTH103 beyond gMG and MMN into CIDP before year end. Like gMG and MMN, CIDP has significant unmet needs where a best-in-class, potent classical pathway inhibitor can potentially make a meaningful difference in the lives of patients. We believe this single, two-part, pivotal Phase 3 trial will support BLA filing in adult patients with CIDP and we anticipate initiating the trial by year-end 2024,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “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 most recently presented at AANEM and ICNMD and competitor clinical data that further validate targeting the classical pathway and active C1s.”

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.
• Poster presentations at AANEM and ICNMD: Encore poster presentations at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) Annual Meeting in Savannah, Georgia and at the 18^th International Congress on Neuromuscular Diseases (ICNMD) in Perth, Australia highlighted preclinical and in vitro data describing the potentially differentiated profile of DNTH103 in a disease model of gMG.

Multifocal Motor Neuropathy (MMN)

• Phase 2 MoMeNtum MMN trial ongoing: The MoMeNtum trial is a global, randomized, double-blind, placebo-controlled Phase 2 trial designed to evaluate the safety, tolerability, and efficacy of DNTH103 in patients with MMN, and it remains on track to report top-line results in 2H’26.

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

• Initiation of a Phase 3 trial in CIDP anticipated by YE’24: Dianthus plans to initiate a single, two-part, randomized withdrawal Phase 3 trial of DNTH103 in CIDP by YE’24. In the open label Part A of this trial, participants will be administered a loading dose followed by 300mg DNTH103 administered every 2 weeks (Q2W) via subcutaneous (S.C.) injection for up to 13 weeks. Part A includes an interim responder analysis of a pre-defined number of participants. Only participants who respond to DNTH103 in Part A will be randomized into Part B, a double-blind, placebo-controlled treatment period of up to 52 weeks, where they will be assessed for prevention of relapse, safety and tolerability, followed by an open-label extension period. The Company believes this single pivotal trial will support BLA filing in adult patients with CIDP. Additional details regarding Phase 3 trial design and timelines will be provided by YE’24.
• Poster presentations at AANEM and ICNMD: Encore poster presentations at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) Annual Meeting in Savannah, Georgia and at the 18^th International Congress on Neuromuscular Diseases (ICNMD) in Perth, Australia highlighted preclinical and in vitro data describing the potentially differentiated profile of DNTH103 in a disease model of CIDP, in addition to head-to-head affinity and pharmacodynamic (PD) potency data for DNTH103 compared to riliprubart.

Corporate Updates

• Effective September 16, 2024, Steven Romano, M.D., was appointed to the Dianthus Therapeutics Board of Directors. Dr. Romano is a pharmaceutical executive with more than 28 years of experience in drug development across a wide range of therapeutic and disease areas. He currently serves as Executive Vice President, Chief Research and Development Officer at Silence Therapeutics.

Third-Quarter 2024 Financial Results

• Cash Position – $342.6 million of cash, cash equivalents and investments as of September 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 September 30, 2024 were $25.5 million, inclusive of $1.7 million of stock-based compensation, compared to $8.0 million for the quarter ended September 30, 2023, which included $0.4 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 quarter ended September 30, 2024 totaled $6.5 million, inclusive of stock-based compensation of $2.2 million, compared to $8.7 million for the quarter ended September 30, 2023, which included $0.8 million of stock-based compensation. This decrease in G&A expenses was primarily due to lower personnel costs.
• Net Loss – Net loss for the quarter ended September 30, 2024 was $25.2 million or $0.74 per share (basic and diluted) compared to $14.8 million or $3.78 per share (basic and diluted) for the quarter ended September 30, 2023.

Session: Muscle and Neuromuscular Junction Disorder 2; Presentation Number: EPR-243

These posters will be made available in the Scientific Publications section of the Dianthus website after they are presented.

“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. Similarly, treatment options for patients with CIDP have traditionally been limited to intravenous or subcutaneous infusions of Ig,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We aim to demonstrate that DNTH103 may become a best-in-class classical complement pathway inhibitor with infrequent self-administration that provides effective and consistent control of symptoms for people living with neuromuscular conditions, without inhibiting the alternative and lectin pathways that are critical in the defense against infection.”

Top-line results from Phase 2 MoMeNtum trial in Multifocal Motor Neuropathy anticipated in 2H 2026

Building a neuromuscular franchise with DNTH103 following the initiation of the Phase 2 MaGic trial in generalized Myasthenia Gravis (gMG) in 1Q’24 and planned initiation of a Phase 2 trial in Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) in 2H’24

Recently disclosed head-to-head affinity and PD potency data reinforce DNTH103 is a highly potent, potential best-in-class active C1s inhibitor designed for self-administration in a low-volume, subcutaneous autoinjector once every two weeks

NEW YORK and WALTHAM, Mass., June 12, 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 U.S. Food and Drug Administration (FDA) clearance of its Phase 2 Investigational New Drug (IND) application for the MoMeNtum trial of DNTH103 in patients with Multifocal Motor Neuropathy (MMN).

“Pre-clinical and clinical evidence support the classical pathway’s role in the pathology seen in MMN,” said Simrat Randhawa, MD, Chief Medical Officer of Dianthus Therapeutics. “DNTH103 is a potent and highly selective inhibitor of active C1s resulting in classical pathway inhibition, without inhibiting the alternative and lectin pathways that are critical in the defense against infection. The Dianthus medical team and our MMN steering committee are excited to investigate the potential benefits DNTH103 may bring to MMN patients.”

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 36 patients with MMN. Following determination of Ig dependency and responsiveness, patients will be randomized to receive placebo or DNTH103 administered subcutaneously (S.C.) every two weeks (Q2W). The initial S.C. treatment duration is expected to be 17 weeks followed by a 52-week open label extension. The primary endpoint of this study is safety and tolerability. Secondary endpoints include time to IVIg retreatment, time to relapse, and assessments of muscle and grip strength. Initial top-line results from this trial are anticipated to be available in the second half of 2026.

“There is a significant unmet medical need for a targeted biologic to treat patients living with MMN,” said Hans Katzberg, MD, MSc, FRCPC, Associate Professor of Neurology, University of Toronto, Prosserman Centre of Neuromuscular Disease. “Today, treatments for MMN are limited to intravenous or subcutaneous infusions of Ig, which can be both inconvenient for patients and difficult to tolerate. Treating MMN with an active C1s inhibitor, like DNTH103, has the potential to transform the lives of these patients.”

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 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.

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.

Top-line results from gMG MaGic trial anticipated in 2H 2025

Building a neuromuscular franchise with DNTH103 through additional planned Phase 2 trials in Multifocal Motor Neuropathy (MMN) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

DNTH103 is a potential best-in-class, potent classical pathway inhibitor planned for self-administration as a low volume, subcutaneous injection once every two weeks

NEW YORK and WALTHAM, Mass., Feb. 26, 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 the initiation of the Phase 2 MaGic trial of DNTH103 in patients with generalized Myasthenia Gravis. The initiation follows U.S. Food and Drug Administration (FDA) clearance of the Phase 2 Investigational New Drug (IND) application for DNTH103. Top-line results from this trial are anticipated in the second half of 2025.

“Following our encouraging Phase 1 data demonstrating a 60-day half-life and potent, specific classical pathway inhibition, we are excited to rapidly advance DNTH103, our investigational active C1s inhibitor, into a Phase 2 study in generalized Myasthenia Gravis,” said Simrat Randhawa, M.D., Chief Medical Officer of Dianthus Therapeutics. “DNTH103 provides a unique approach to complement inhibition in gMG, which could result in a more convenient and safer alternative for patients versus current options.”

The MaGic trial is a global, randomized, double-blind, placebo-controlled Phase 2 study in up to 60 patients with generalized Myasthenia Gravis who are acetylcholine receptor (AchR) antibody positive. Following an initial loading dose, DNTH103 will be administered every two weeks (Q2W) via subcutaneous (S.C.) injection. The S.C. treatment duration will initially be 12 weeks with a 52-week open label extension. The primary endpoint of the study is safety and tolerability. Secondary endpoints include Myasthenia Gravis Activities of Daily Living Scale (MG-ADL) and Quantitative Myasthenia Gravis (QMG) score assessments. Initial top-line results from this trial are anticipated to be available in the second half of 2025.

“For patients with AchR-positive gMG, inappropriate activation of the complement classical pathway is a major driver of disease pathology and therefore patient symptoms,” said Mazen M. Dimachkie, M.D., Professor of Neurology and Director of Neuromuscular Division at the University of Kansas Medical Center. “I am excited to collaborate with Dianthus to evaluate this investigational, highly specific classical pathway inhibitor that could fill the need for a more convenient and safe complement inhibitor for my gMG patients.”
