Clearance of CD38-SADA IND marks the second clinical development program utilizing the Company’s novel SADA technology platform
NEW YORK, Oct. 17, 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 the U.S. Food and Drug Administration (“FDA”) has cleared the Company’s Investigational New Drug (“IND”) application for CD38-SADA, the Company’s second program within its Self-Assembly DisAssembly Pre-targeted Radioimmunotherapy (“SADA Y-PRIT”) Theranostic Platform. The Phase 1 trial is a first-in-human, dose-escalation, open-label, single-arm, multi-center trial (Study 1201) investigating the safety and tolerability of the CD38-SADA: 177Lu-DOTA Drug Complex in patients with Relapsed or Refractory non-Hodgkin Lymphoma.
This trial will have two parts: Part A, CD38-SADA dose escalation with fixed 177Lu-DOTA payload doses to explore optimal CD38-SADA protein dose and interval between the SADA protein administration and the payload; and Part B, 177Lu-DOTA therapeutic dose escalation with the CD38-SADA dose determined in Part A. Patients will receive up to three cycles of therapy. The primary study outcome will evaluate safety and initial signals of efficacy using repeated dosing. Y-mAbs expects a total of approximately 30 patients and up to 12 U.S. sites to be included in the trial.
The CD38-SADA construct was created using SADA technology, which was licensed by the Company from Memorial Sloan Kettering Cancer Center (“MSK”) and Massachusetts Institute of Technology (“MIT”) in April 2020. The SADA technology platform utilizes a pre-targeted payload delivery method where antibody constructs assemble in tetramers and bind to the tumor target. Unbound constructs predictably disassemble into smaller antibody fragments and are predominantly excreted through the kidneys within hours after administration. In a second infusion, a radioactive payload binds to the antibody constructs attached to the tumor target in order to radiate the tumor. This provides the possibility of targeting tumors with precision while minimizing radiation of normal tissues. We believe that the SADA technology platform can deliver a variety of payloads and could potentially be developed against multiple tumor targets, as well as for theragnostic purposes.
“We are pleased by the FDA clearance of our IND for CD38-SADA, marking the second program utilizing our novel SADA technology platform to enter clinic development within just 15 months,” said Thomas Gad, Founder, President and Interim Chief Executive Officer. “With our team’s proven CD38-targeted drug development track record and our unique two-step SADA mechanism, we believe our CD38-SADA program has the potential to address a clear unmet medical need. We are incredibly excited about the potential of SADA to transform the treatment paradigm across a variety of targets.”
“The FDA clearance of our IND paves the way for a new way of addressing CD38-positive tumors, with the potential for CD38-SADA to be a key addition to the physician toolbox in treating Relapsed or Refractory non-Hodgkin Lymphoma patients of both of B-cell and T-cell origin,” said Steen Lisby, M.D., DMSc, SVP and Chief Scientific Officer, Global Head of Translational Medicine. “Despite the growing range of available treatment options for patients with lymphoma, many patients will develop disease that no longer responds to treatment and risk succumbing to the disease. Hence, there is still significant unmet medical need in Relapsed or Refractory non-Hodgkin Lymphoma. CD38-SADA marks our first hematology radiotherapy program. We look forward to initiating this Phase 1 trial and expect to dose the first patient in 2024.”
Researchers at MSK, including Dr. Cheung, developed the SADA technology for radioimmunotherapy, which is exclusively licensed by MSK to Y-mAbs. Dr. Cheung has intellectual property rights and interests in the technology, and as a result of this licensing arrangement, MSK has institutional financial interests in the technology and in Y-mAbs.
