NEW YORK, May 26, 2023 (GLOBE NEWSWIRE) -- Y-mAbs Therapeutics, Inc. (the “Company” or “Y-mAbs”) (Nasdaq: YMAB) a commercial-stage biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic products for the treatment of cancer, today announced that a poster presentation featuring the design of its Phase 1 clinical trial, evaluating the Company’s Self-Assembly DisAssembly Pre-targeted Radioimmunotherapy (“SADA Y-PRIT”) Theranostic Platform for the treatment of certain GD2-positive solid tumors, including small cell lung cancer, sarcoma and malignant melanoma will be presented at the American Society of Clinical Oncology (“ASCO”) Annual Meeting to be held June 2-6, 2023 in Chicago, Illinois.
The Phase 1 dose-escalation, single-arm, open-label, non-randomized, multicenter trial (NCT05130255) has three parts: Part A will explore dose-finding for the GD2-SADA molecule and testing of dosing intervals between the protein and the 177Lu-DOTA payload; Part B will determine the optimal dose of 177Lu-DOTA; and Part C will evaluate safety and initial signals of efficacy using repeated dosing. Dose escalation is based two patients in cohort 1 and 2, followed by a classical 3+3 design. The study is actively enrolling, and the Company expects Parts A, B, and C will include 18, 12, and 32 patients, respectively, across 6-10 U.S. sites.
The GD2-SADA construct was created using the Company’s SADA Y-PRIT Theranostic Platform, which was licensed by the Company from Memorial Sloan Kettering Cancer Center (“MSK”) and Massachusetts Institute of Technology (“MIT”). In research, it was shown that SADA Y-PRIT utilizes a pre-targeted payload delivery method where antibody constructs assemble into tetramers and bind to the tumor target. In prior nonclinical studies, unbound constructs predictably disassembled into smaller antibody fragments and were taken up by the liver or excreted through the kidneys within a few days after administration. In a second infusion, a radioactive payload designed specifically to target the SADA molecules attached to the tumor target. Y-mAbs believes this approach provides the possibility of targeting tumors with precision while minimizing radiation of normal tissues, and that the SADA Y-PRIT Theranostic Platform may have the potential to deliver a variety of payloads and be developed against multiple tumor targets, as well as for theranostic purposes.
Researchers at MSK developed the SADA technology for radioimmunotherapy, which is exclusively licensed by MSK to Y-mAbs. MSK has institutional financial interests related to the technology and Y-mAbs.
Y-mAbs is a commercial-stage biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic cancer products. In addition to conventional antibodies, the Company’s technologies include bispecific antibodies generated using the Y-BiClone platform and the SADA platform. The Company’s broad and advanced product pipeline includes one FDA-approved product, DANYELZA® (naxitamab-gqgk), which targets tumors that express GD2, and one product candidate, OMBLASTYS® (omburtamab), which targets tumors that express B7-H3.
