Who We Are
We envision the full potential of complement therapeutics lies within the power of selectivity. Our lead antibody, DNTH103, is purposefully engineered with extended half-life, improved potency, and high selectivity for only the active C1s complement protein that drives disease pathology – enabling less frequent and more convenient self-administered subcutaneous injections to improve the lives of patients.
Team
We are a multidisciplinary team of biotech entrepreneurs and scientists united by our commitment to deliver novel and highly differentiated monoclonal antibodies to target validated and emerging complement targets with improved selectivity and potency over existing therapies.

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 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.

NEW YORK and WALTHAM, Mass., June 28, 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 two poster presentations for DNTH103 at the 10th Congress of the European Academy of Neurology (EAN), taking place June 29-July 2, 2024 in Helsinki.
DNTH103 is an investigational classical pathway inhibitor that is uniquely specific to the active form of C1s, and is being evaluated for its potential as an effective, low-volume, convenient and safe treatment option for patients with generalized Myasthenia Gravis, Multifocal Motor Neuropathy, and Chronic Inflammatory Demyelinating Polyneuropathy.
Two poster presentations at EAN will highlight preclinical and in vitro data describing the potentially differentiated profile of DNTH103 in disease models of generalized Myasthenia Gravis (gMG) and Chronic Demyelinating Polyneuropathy (CIDP), in addition to head-to-head affinity and pharmacodynamic (PD) potency data for DNTH103 compared to Riliprubart.
Dianthus Presentations at EAN:
June 29, 2024, 14:10 EEST
DNTH103, a Potentially Safer and More Convenient Novel Therapy for Generalised Myasthenia Gravis
Session: Muscle and Neuromuscular Junction Disorder 1; Presentation Number: EPR-118
June 30, 2024, 14:25 EEST
DNTH103: Preventing Nerve Damage in a CIDP Model via Sustained Complement Inhibition
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.”

Phase 2 MaGic trial in generalized Myasthenia Gravis (gMG) ongoing, with top-line results anticipated in 2H’25
Building a neuromuscular franchise with DNTH103; Phase 2 trial in Multifocal Motor Neuropathy (MMN) to initiate 2Q’24 and Phase 2 trial in Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) to initiate 2H’24
$377 million of cash, including proceeds from a successful $230 million PIPE financing completed in January 2024, provides runway into 2H 2027
NEW YORK and WALTHAM, Mass., May 09, 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 first quarter ending March 31, 2024, and provided an update on recent business achievements.
“The first quarter of 2024 was highlighted by the initiation of our Phase 2 MaGic trial of DNTH103 for patients with gMG. We are also encouraged by recently published proof-of-concept clinical trial data that continues to validate active C1s as a target for treating CIDP, enhancing our confidence in the pipeline-in-a-product potential for DNTH103 across multiple autoimmune diseases,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We remain on track to initiate our Phase 2 clinical trials in MMN and CIDP this year as well.”
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 was presented at the AAN 2024 Annual Meeting.
- Planning for MMN and CIDP Phase 2 trials ongoing: Dianthus expects to initiate additional Phase 2 trials of DNTH103 in MMN in the second quarter of 2024 and 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.
First-Quarter 2024 Financial Results
- Cash Position – $377.0 million of cash, cash equivalents and short-term investments as of March 31, 2024 is projected to provide runway into 2H 2027.
- R&D Expenses – Research and development (R&D) expenses for the quarter ended March 31, 2024 were $13.1 million, inclusive of $0.8 million of stock-based compensation, compared to $5.8 million for the quarter ended March 31, 2023, which included $0.2 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, partially offset by lower pre-clinical costs.
- G&A Expenses – General and administrative (G&A) expenses for the quarter ended March 31, 2024 totaled $5.6 million, inclusive of stock-based compensation of $1.2 million, compared to $2.3 million for the quarter ended March 31, 2023, which included $0.3 million of stock-based compensation. This increase in G&A expenses was primarily due to higher headcount and professional fees.
- Net Loss – Net loss for the quarter ended March 31, 2024 was $13.7 million or $0.54 net loss per share (basic and diluted) compared to $7.1 million or $8.10 net loss per share (basic and diluted) for the quarter ended March 31, 2023.
- Additional Information – For additional information on the Company’s financial results for the quarter ended March 31, 2024, please refer to the Form 10-Q filed with the SEC.

NEW YORK and WALTHAM, Mass., April 11, 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 an oral presentation for DNTH103 at the American Academy of Neurology (AAN) Annual Meeting, taking place April 13-18, 2024 in Denver, Colorado and virtually.
DNTH103 is an investigational classical pathway inhibitor that is uniquely specific to the active form of C1s, and is being evaluated for its potential as an effective, low-volume, convenient and safe treatment option for patients with generalized Myasthenia Gravis, Multifocal Motor Neuropathy, and Chronic Inflammatory Demyelinating Polyneuropathy. The oral presentation at AAN will highlight 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.
“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,” said Marino Garcia, Chief Executive Officer of Dianthus Therapeutics. “We aim to demonstrate that DNTH103 may be a best-in-class treatment option with improved safety and infrequent self-administration that provides effective and consistent control of symptoms for people living with neuromuscular conditions.”
Oral Presentation Details:
April 15, 2024, 1:00 PM MT / 3:00 PM ET
Classical Pathway Inhibition with Anti-Active C1s Antibody DNTH103 Prevents Neurotransmission Impairment in a Preclinical Model of Myasthenia Gravis

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.

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.”

Began trading on Nasdaq under the ticker symbol DNTH following the successful completion of our merger with Magenta Therapeutics
Completed concurrent $72 million financing with a syndicate of leading life-science investors
Announced positive top-line Phase 1 data for lead clinical program, DNTH103, confirming potent classical complement pathway inhibition, extended half-life, and a potentially differentiated safety profile
On track to advance DNTH103 into Phase 2 trials targeting multiple neuromuscular indications in 2024, starting with generalized Myasthenia Gravis in Q1 2024
Robust balance sheet, closing the quarter with over $189 million of cash runway expected to fund operations into Q2 2026
NEW YORK and WALTHAM, Mass., Nov. 09, 2023 (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, 2023 and provided an update on recent business achievements.
“This was a landmark quarter of progress and momentum for Dianthus, marked by the positive top-line results for our lead clinical program, DNTH103, validating its best-in-class potential as well as our exciting transition to the public markets with a robust balance sheet,” said Marino Garcia, President and Chief Executive Officer of Dianthus Therapeutics. “As we look ahead, we remain on track to progress DNTH103 into Phase 2 trials for multiple neuromuscular indications where we have the potential to develop a new standard of care, beginning with generalized Myasthenia Gravis in the first quarter of 2024, followed by Multifocal Motor Neuropathy and Chronic Inflammatory Demyelinating Polyneuropathy. We’re particularly energized by the high level of engagement and interest we’ve seen from leading clinicians and investigators globally due to DNTH103’s potentially differentiated profile as a potent active C1s inhibitor with infrequent, subcutaneous self-administration. We are encouraged by the potential of DNTH103 to address both the disease and treatment burdens that disrupt the lives of patients suffering from severe autoimmune diseases, and we look forward to providing updates on our progress in the coming months.”
Recent Business Highlights and Upcoming Milestones
DNTH103
DNTH103 is an investigational, potent monoclonal antibody designed to selectively target the active form of the C1s protein, a clinically validated complement target within the classical pathway. 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. Engineered with validated YTE half-life extension technology, DNTH103 is intended to be the first subcutaneous complement therapy that can be self-administered as infrequently as once every two weeks for a range of severe, classical pathway-driven autoimmune disorders, beginning with generalized Myasthenia Gravis (gMG), Multifocal Motor Neuropathy (MMN), and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).
- Top-line Phase 1 data across seven single and multiple ascending dose cohorts with 52 healthy volunteers establish DNTH103’s best-in-class potential. Results confirmed:
- Approximately 60-day half-life and highly potent classical pathway inhibition
- A potentially differentiated safety profile, with no serious adverse events or complement-related infections
- In a well-established, functional in vitro AChR-positive model of gMG disease, DNTH103 improved neurotransmission and muscle contraction, providing further scientific rationale and support for targeting the classical pathway with DNTH103 in AChR-positive gMG patients.
- Dianthus intends to initiate Phase 2 trials of DNTH103 for gMG in the first quarter of 2024, followed by MMN in the first half of 2024 and CIDP in the second half of 2024.
Corporate
- Successfully completed merger with Magenta Therapeutics and began trading on Nasdaq under the new ticker symbol “DNTH” with over $189 million of cash runway expected to fund operations into Q2 2026.
- Concurrent with the closing of the merger, completed a $72 million private investment in common stock and pre-funded warrants from a syndicate of healthcare investors led by Fidelity Management & Research Company, Catalio Capital Management, 5AM Ventures, Avidity Partners, Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures and Venrock Healthcare Capital Partners.
- Further strengthened Board of Directors with appointments of Alison Lawton and Anne McGeorge.
Third Quarter Financial Results
- Cash, cash equivalents, and investments totaled $189.9 million on September 30, 2023.
- Research and development expenses for the quarter ended September 30, 2023 were $8.0 million, inclusive of $0.4 million of stock-based compensation.
- General and administrative expenses for the quarter ended September 30, 2023 were $8.7 million, inclusive of severance costs for legacy Magenta employees of $4.0 million and stock-based compensation of $0.8 million.
- Net loss for the quarter ended September 30, 2023 was $14.8 million or $3.78 net loss per share (basic and diluted).
- For additional information on the Company’s financial results for the quarter ended September 30, 2023, please refer to the Form 10-Q filed with the SEC.
About DNTH103
DNTH103 is an investigational, long-acting monoclonal antibody designed to selectively target the active form of the C1s protein, a clinically validated complement target within the classical pathway. 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 plans to initiate Phase 2 trials in multiple neuromuscular indications in 2024, starting with generalized Myasthenia Gravis in the first quarter of 2024.

Positive top-line Phase 1 data for lead clinical program DNTH103 confirm potent classical pathway inhibition, extended half-life, and a potentially differentiated safety profile
Results support DNTH103’s best-in-class potential to be the first subcutaneous, self-administered injection dosed as infrequently as once every two weeks to treat a range of autoimmune disorders
Company plans to initiate multiple Phase 2 trials targeting neuromuscular indications in 2024, starting with generalized Myasthenia Gravis in Q1 2024, followed by Multifocal Motor Neuropathy in Q2 2024, and Chronic Inflammatory Demyelinating Polyneuropathy in second half of 2024
Dianthus Therapeutics, Inc. will begin trading on Nasdaq as DNTH with approximately $184 million of cash runway expected to fund operations into Q2 2026
NEW YORK and WALTHAM, Mass., Sept. 12, 2023 (GLOBE NEWSWIRE) — Dianthus Therapeutics, Inc. (“Dianthus”), a clinical-stage biotechnology company dedicated to advancing the next generation of antibody complement therapeutics to treat severe autoimmune diseases, today announced positive top-line Phase 1 data for DNTH103 validating its best-in-class potential as a selective classical pathway inhibitor targeting only the active form of the C1s protein. Additionally, Dianthus will begin trading on the Nasdaq Capital Market today as DNTH, following the successful completion on September 11, 2023 of the previously announced merger with Magenta Therapeutics (“Magenta”).
The Phase 1 healthy volunteer study was designed to validate the extended half-life, potent classical pathway inhibition, and potentially differentiated safety profile of DNTH103. Top-line data across seven single and multiple ascending dose cohorts with 52 healthy volunteers confirmed its approximately 60-day half-life and highly potent classical pathway inhibition, establishing DNTH103’s best-in-class potential to be the first self-administered subcutaneous injection dosed as infrequently as once every two weeks to treat a range of autoimmune disorders. The results also demonstrated DNTH103 was generally well tolerated with no serious adverse events or complement-related infections. Dianthus plans to initiate multiple Phase 2 studies in 2024 in various neuromuscular indications, starting with generalized Myasthenia Gravis (gMG) in the first quarter of 2024 followed by additional Phase 2 trials for Multifocal Motor Neuropathy (MMN) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). Additional information about our Phase 1 data and DNTH103 can be found in our corporate presentation at investor.dianthustx.com.
“This is an exciting and transformative time at Dianthus as we announce top-line Phase 1 data for DNTH103 validating its potential to become a new standard of care with a best-in-class profile for multiple classical pathway-driven autoimmune disorders,” said Marino Garcia, President and Chief Executive Officer of Dianthus Therapeutics. “These results, combined with our transition to the public markets, represent a major milestone in our growth trajectory. We are now well positioned to execute across multiple Phase 2 trials as we continue to maximize the value of DNTH103 as a pipeline-in-a-product.”
“I am very encouraged by the Phase 1 safety and pharmacokinetic/pharmacodynamic data seen with DNTH103, our highly potent and selective upstream classical complement pathway inhibitor. Classical pathway activation plays a significant role in the pathology of various autoimmune disorders such as generalized Myasthenia Gravis, where patients still face significant disease and treatment burden, and we are excited to start the gMG Phase 2 trial early next year,” said Simrat Randhawa, M.D., Chief Medical Officer of Dianthus Therapeutics. “We also look forward to starting Phase 2 trials in both MMN and CIDP in 2024, two neuromuscular autoimmune disorders which currently have no approved targeted biologics and where we believe DNTH103 could benefit patients.”
Concurrent with the closing of the merger, Dianthus completed a $72 million private investment in its common stock and pre-funded warrants from a syndicate of healthcare investors led by Fidelity Management & Research Company, Catalio Capital Management, 5AM Ventures, Avidity Partners, Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures and Venrock Healthcare Capital Partners. The cash and cash equivalents as of the close of the business combination were approximately $184 million, which is expected to provide cash runway into the second quarter of 2026.
About DNTH103
DNTH103 is a 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 plans to initiate Phase 2 trials in multiple neuromuscular indications in 2024, starting with generalized Myasthenia Gravis in the first quarter of 2024.

About DNTH103
DNTH103 is an investigational long-acting classical complement pathway inhibitor designed as a less frequent and convenient subcutaneous injection with the potential to treat people living with severe autoimmune diseases. DNTH103, a fully human monoclonal antibody, is designed to selectively target only the active form of the C1s complement protein, inhibiting only the classical complement pathway, with the aim of treating patients with a lower dosing volume as a convenient subcutaneous injection suitable for a self-administered pre-filled pen. Inhibiting the active form of the complement target seeks to address a critical treatment gap in current complement therapies that do not bind selectively to the active protein, wasting a significant amount of the drug on inert proteins. DNTH103 selective inhibition of the classical pathway is engineered to preserve important immune activity of the lectin and alternative complement pathways needed to protect the body against infections from encapsulated bacteria. DNTH103 is also enhanced with YTE half-life extension technology to further reduce dosing frequency.
DNTH103 has a steady cadence of expected clinical milestones including top-line Phase 1 data aiming to confirm potent classical pathway inhibition and favorable, extended pharmacokinetics expected by the end of 2023, initiation of a Phase 2 trial in generalized Myasthenia Gravis expected in the first quarter of 2024 followed by two additional planned Phase 2 trial initiations in Multifocal Motor Neuropathy (MMN) and Chronic inflammatory demyelinating polyneuropathy (CIDP). Dianthus also plans to initiate an open label proof of efficacy trial in Cold Agglutinin Disease (CAD) with patient data anticipated in the second half of 2024.

Study of lead program will provide proof-of-concept to enable further clinical development in severe autoimmune diseases; full cohort data available in 2H’23
DNTH103 is a next-generation monoclonal antibody that selectively targets only the active form of the C1s protein in the classical complement pathway
DNTH103 designed as an infrequent and convenient subcutaneous injection to improve upon high dose volume and frequency of currently available complement pathway inhibitors
New York City and Waltham, Mass., November 30, 2022 – Dianthus Therapeutics, a biotechnology company dedicated to advancing the next generation of antibody complement therapeutics, today announced that the first healthy volunteers have been dosed in a Phase 1 clinical trial of its lead monoclonal antibody, DNTH103.
“Today marks a pivotal milestone for Dianthus as we transition into a clinical stage company,” said Marino Garcia, President and Chief Executive Officer, Dianthus Therapeutics. “Data from this Phase 1 study will provide important information about the safety, tolerability, pharmacokinetics and pharmacodynamics of DNTH103 in healthy adult volunteers across single and multiple ascending dose cohorts, demonstrating potential proof-of-concept to advance DNTH103 into severe autoimmune diseases where other modalities have not fully addressed the unmet medical need.”
DNTH103 is a selective inhibitor of the active C1s protein in the complement system’s classical pathway. Classical pathway activity is implicated in driving morbidity in a range of autoimmune disorders. Unlike therapies that broadly inhibit the complement system, selective inhibition of the classical pathway preserves immune activity of the lectin and alternative complement pathways against bacterial infections.
“All currently approved complement antibody therapies indiscriminately bind to both active and inactive complement proteins – meaning a large, sometimes frequent dose must be administered while a significant portion of the drug acts unnecessarily on inert proteins,” said Simrat Randhawa, M.D., Chief Medical Officer, Dianthus Therapeutics. “DNTH103 selectively targets the active form of C1s – allowing more of the drug to have a therapeutic effect so we can potentially reduce dose volume and frequency of administration. In addition, by leaving the lectin and alternative pathways intact, the risk of infection from encapsulated bacteria is lower for DNTH103 versus commonly used C5 and C3 inhibitors.”
About Dianthus Therapeutics
Dianthus Therapeutics is a clinical-stage biotechnology company dedicated to designing and delivering novel, best-in-class monoclonal antibodies with improved selectivity and potency over existing complement therapies. Based in New York City and Waltham, Mass. Dianthus is comprised of an expert team of biotech and pharma executives who are leading the next generation of antibody complement therapeutics to deliver transformative medicines for patients with severe autoimmune diseases. Dianthus raised a $100M Series A in April 2022 co-led by 5AM Ventures, Avidity Partners, and Fidelity Management & Research Company, with participation from additional investors including Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures, and Venrock Healthcare Capital Partners.

Lead program DNTH103 to be accelerated to the clinic this year as a highly differentiated and potent monoclonal antibody designed to selectively target the active form of complement C1s
Led by biotech veterans Marino Garcia as Chief Executive Officer and Lonnie Moulder as Chairman of the Board
Financing co-led by 5AM Ventures, Avidity Partners, and Fidelity Management & Research Company with strong investor syndicate
Waltham, Mass. and New York City, May 3, 2022 – Dianthus Therapeutics, a biotechnology company dedicated to advancing the next generation of antibody complement therapeutics, today announced the completion of its $100 million Series A financing led by 5AM Ventures, Avidity Partners, and Fidelity Management & Research Company, with participation from additional investors including Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures, and Venrock Healthcare Capital Partners. The financing will be used to expand leadership and scientific teams, advance the company’s lead program, DNTH103, to the clinic this year, and to accelerate additional discovery pipeline programs for people living with severe and rare autoimmune diseases. DNTH103 is a potent, next-generation monoclonal antibody that selectively targets the active form of complement C1s, potentially enabling a lower dosing volume and a less frequent subcutaneous administration that is further enhanced with half-life extension technology.
Dianthus also announced the appointment of Marino Garcia as President and Chief Executive Officer, joining in November 2021, and Simrat Randhawa, M.D., M.B.A., as Chief Medical Officer. Mr. Garcia, a veteran dealmaker and strategist, brings more than 25 years of industry experience in business development and operational leadership roles at top biotech and pharma companies, most recently as Senior Vice President, Corporate and Business Development at Zealand Pharma. Dr. Randhawa brings over 20 years of clinical practice and pharmaceutical industry experience to Dianthus, including senior leadership roles focused in the autoimmune and rare disease spaces. He most recently served as Senior Vice President of Clinical and Medical Affairs at Aurinia Pharmaceuticals.
“We are committed to improving the lives of people living with severe and rare autoimmune diseases and are confident that our selective antibodies have the potential to be best-in-class therapeutics,” said Marino Garcia, President and Chief Executive Officer, Dianthus Therapeutics. “We are privileged to have a strong syndicate of leading biotech investors, experienced Board members, and accomplished leaders and scientists as we advance our lead candidate into the clinic later this year, further develop our discovery pipeline, and expand our team in the coming months. Dianthus is positioned to become a leading, next-generation complement company guided by a deep understanding of the needs of patients.”
Dianthus harnesses the power of selectivity in complement pathways to create potent monoclonal antibodies with the potential to overcome the limitations of current complement therapeutics. Unlike current antibody therapies that bind to both inactive and active complement proteins, DNTH103 selectively targets only the active form of the C1s complement protein, enabling a lower dosing volume and less frequent administration. Its half-life extension technology also further reduces dosing frequency. With these differentiated attributes and high potency inhibition of C1s, DNTH103 is designed to relieve the burden of high-volume, frequent administration with IV infusions or inconvenient, frequent subcutaneous dosing. Accelerating the development of a more convenient subcutaneous therapy could be transformative in expanding the potential patient populations that could benefit from complement therapies, while reducing the discomfort and disruptions that pervade the lives of patients today – ultimately allowing more patients to live healthier lives to their fullest potential.
“We are proud to support Dianthus Therapeutics in advancing the discovery and development of next-generation, potent, and highly differentiated antibody complement therapeutics,” said Paula Soteropoulos, Board Director of Dianthus and Strategic Advisor to 5AM Ventures. “With the leadership of the recently appointed President and CEO Marino Garcia, and a talented team of seasoned biotech executives and entrepreneurs who hold an extensive track record of success, we look forward to seeing Dianthus bring their novel therapies to patients living with severe and rare autoimmune diseases.”

- Marino Garcia, President and Chief Executive Officer
- Simrat Randhawa, M.D.,Chief Medical Officer
- Evan Thompson, Ph.D.,Chief Operating Officer
- Edward Carr,Chief Accounting Officer
- Rivka Gluck,Senior Vice President, Head of Clinical Operations
