• The FDA has cleared SystImmune's Investigational New Drug (IND) application for BL-M11D1, an antibody-drug conjugate (ADC), for relapsed/refractory Acute Myeloid Leukemia (AML).
• BL-M11D1 targets CD33, a protein expressed on myeloid cells, and is designed to trigger antibody-dependent cellular cytotoxicity (ADCC) and induce tumor cell death.
• A Phase 1 clinical trial, BLM11D1-HM-101, is set to begin in the United States to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of BL-M11D1.
• BL-M11D1 comprises a monoclonal antibody binding CD33 and a topoisomerase I inhibitor payload, potentially offering a novel therapeutic option for AML patients.
