The possibility of a 2025 approval looks to be off the table for Actinium Pharmaceuticals Inc.’s Iomab-B, at least in the U.S. In a move that H.C. Wainwright analyst Joseph Pantginis dubbed “a major surprise,” the FDA has requested a head-to-head study demonstrating overall survival before it will consider approving the radiotherapy candidate for use in patients with active relapsed or refractory acute myeloid leukemia.
Plexium Inc. has reported the discovery and preclinical characterization of PLX-3618, a novel monovalent direct degrader of BRD4 being developed for the treatment of cancer.
University of Regensburg has described water-soluble FLT3 (FLK2/STK1) inhibitors and their prodrugs reported to be useful for the treatment of acute myeloid leukemia (AML).
Researchers from the Center for Applied Medical Research (CIMA) in Spain have published preclinical data for two new histone deacetylase (HDAC) inhibitors – CM-444 and CM-1758 – being developed for the treatment of acute myeloid leukemia (AML).
Researchers from Molecular Partners AG reported on the preclinical evaluation of MP-0533, a multispecific T-cell engaging DARPin (designed ankyrin repeat protein) targeting CD70, CD123, CD33 and CD3 tumor-associated antigens (TAA) simultaneously.
Newco Yellowstone Biosciences Ltd. has been formed to develop soluble bispecific T-cell receptors against a novel class of tumor-specific antigens it has discovered in leukemia patients who were cured by a donor stem cell transplant. The company has proprietary access to a biobank of over 10,000 samples from more than 3,000 acute myeloid leukemia (AML) patients. A small number of these patients were cured by an allogeneic bone marrow transplant, whilst unusually, having no sign of graft-vs.-host disease.
Residual leukemic stem cells (LSCs) are leukemia relapse-initiating cells that mediate treatment resistance in response to therapy stress. Different from normal hematopoietic stem cells (HSCs), both blasts and LSCs express T-cell immunoglobulin mucin-3 (TIM-3) on the surface.
Targeting topoisomerase 2 (TOP2) is crucial in AML, and researchers from Wakunaga Pharmaceutical Co. Ltd. have developed and tested racemic WAC-224, a quinolone TOP2 inhibitor, and (R)-WAC-224 as a potential approach for AML treatment.
