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 ETClassical Pathway Inhibition with Anti-Active C1s Antibody DNTH103 Prevents Neurotransmission Impairment in a Preclinical Model of Myasthenia GravisPresenter: Sankalp Gokhale, M.D., Head of Clinical Development, Neurology, Dianthus TherapeuticsSession S15: Autoimmune Neuromuscular Diseases: New Observations and Therapeutic Approaches Program S15.001 Detailed presentation listings for the 2024 AAN Annual Meeting can be found on the meeting website: https://www.aan.com/events/annual-meeting. 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 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.

(Nasdaq: ONCT), a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies, today provided a business update and reported third quarter 2023 financial results. “We continue to execute on our plan to advance both ONCT-534, our dual-action AR inhibitor for patients with advanced prostate cancer who have relapsed or are refractory to treatment with AR pathway inhibitors, and ONCT-808, our ROR1-targeting autologous CAR T for patients with aggressive B cell lymphoma, including those who relapse after CD19 CAR T treatment, towards potential significant clinical inflection points by mid-2024,” said James Breitmeyer, M.D., Ph.D., Oncternal’s President and CEO. “We believe ONCT-534 can address a significant unmet medical need for patients with advanced metastatic prostate cancer, especially those with splice variants of the androgen receptor, mutations in the ligand-binding domain of the AR, or AR amplification, common mechanisms of resistance to treatment with approved AR pathway inhibitors. With ONCT-808, we have seen encouraging expansion and persistence of CAR expressing T cells in our first advanced B-NHL patient, which we believe has been associated with positive responses for other CAR T therapies. We look forward to presenting an initial data update by the end of 2023.” Recent Highlights In October 2023, we announced that the first patient with metastatic castration-resistant prostate cancer (mCRPC) had been dosed in the Phase 1/2 dose escalation/dose expansion study of ONCT-534, our novel dual-action androgen receptor inhibitor (DAARI)In October 2023, the U.S. Food and Drug Administration granted fast track designation for the treatment of adult patients with relapsed or refractory mCRPC resistant to androgen receptor pathway inhibitors (ARPIs)In September and October 2023, we announced the establishment and expansion of our Prostate Cancer Scientific Advisory Board (SAB), which includes distinguished academic and industry leaders in the prostate cancer field, who will provide guidance for the clinical development of ONCT-534 Expected Upcoming Milestones ONCT-808, our autologous ROR1-targeted CAR T cell therapy Initial clinical data available by the end of 2023Additional clinical data readouts in 2024 ONCT-534, our dual-action androgen receptor inhibitor Initial clinical data available in the first half of 2024 Third Quarter 2023 Financial ResultsOur grant revenue was $0.2 million for the third quarter ended September 30, 2023.

About Oncternal Therapeutics Oncternal Therapeutics is a clinical-stage biopharmaceutical company focused on the development of novel oncology therapies for the treatment of patients with cancers that have critical unmet medical need. Oncternal pursues drug development targeting promising, yet untapped biological pathways implicated in cancer generation or progression, focusing on hematological malignancies and prostate cancer. ONCT-534 is an investigational dual-action androgen receptor inhibitor (DAARI) with preclinical activity in prostate cancer models against both unmutated androgen receptor (AR), and against multiple forms of AR aberration. It is a potential treatment for patients with mCRPC with unmet medical need because of resistance to androgen receptor inhibitors, including those with AR amplification, mutations in the AR ligand binding domain (LBD), or splice variants with loss of the AR LBD. Oncternal has initiated Study ONCT-534-101 (NCT05917470), which is open and enrolling patients for treatment with mCRPC. ONCT-808 is an investigational autologous chimeric antigen receptor T (CAR T) cell therapy that targets Receptor Tyrosine Kinase-Like Orphan Receptor 1 (ROR1) using the binding domain from zilovertamab. ONCT-808 has demonstrated activity in preclinical models against multiple hematological malignancies and solid tumors and has been shown to be specific for cancer cells expressing ROR1. Oncternal has developed a robust and reproducible manufacturing process that has the potential to reduce the time patients must wait for their individual CAR T therapy to be produced, compared with currently approved CAR T products. Oncternal has dosed patients under Study ONCT-808-101 (NCT05588440) with relapsed or refractory aggressive B-cell lymphoma, including patients who have failed previous CD19 CAR T treatment. Zilovertamab is an investigational monoclonal antibody designed to inhibit the function of ROR1. Zilovertamab has been evaluated in a Phase 1/2 Study CIRM-0001 (NCT03088878) in combination with ibrutinib for the treatment of patients with mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL) and marginal zone lymphoma (MZL), which resulted in 100% progression free survival (PFS) at 42 months in CLL patients expressing a p53 mutation/del(17p), a population underserved by current treatment options. Zilovertamab is also being evaluated in an investigator-initiated Phase 1b study of zilovertamab in combination with docetaxel in patients with metastatic castration-resistant prostate cancer (NCT05156905).
