Hillstream Biopharma Inc. has signed an exclusive agreement with Applied Biomedical Science Institute (ABSI) to license technology for human antibodies targeting novel HER2 and HER3 conformational epitopes. The goal is to develop proprietary multiformat biologics, including bispecific antibodies and antibody-drug conjugates (ADCs).
TG Immunopharma Co. Ltd. has announced clearance by the FDA for a clinical trial of TGI-6, a bispecific antibody targeting unique tumor-associated antigens (TAA) and CD3 molecules simultaneously, for solid tumors.
Although advances in chemotherapy have dramatically improved outcomes for children with leukemia, patients with high-risk and aggressive cancers require intense drug regimens that push safety limits. Researchers have formulated an antibody guidance system in mice that could empower chemotherapy against childhood leukemias while minimizing drug toxicity.
Bioatla Inc. has received FDA clearance of its IND application to evaluate BA-3182, a conditionally active biologic (CAB) EpCAM/CD3 bispecific T-cell engager antibody, for the treatment of advanced adenocarcinoma. The company plans to initiate a phase I study this year.
Ocean Biomedical Inc. has discovered bispecific antibodies that target Chitinase 3-like-1 (CHI3L1) and immune checkpoint inhibitors, killing glioblastoma cells and melanoma cells, and blocking the metastasis of malignant melanoma cells to the lung by over 90%.
Centessa Pharmaceuticals plc has received clearance of its IND application from the FDA to initiate a first-in-human phase I/IIa trial of LB-101 for the treatment of solid tumors.
The advent of bispecific antibodies bridging two different cell types has enabled a new level of cell specificity in cancer biology that has only recently begun to be realized in the clinic.
Researchers at GM Biosciences Inc. have reported developed a novel CD38xCD3 bispecific IgM T-cell engager IGM-2644 with 10 binding sites for human CD38 (Kd=0.27nM; measured by biolayer interferometry) and one anti-CD3 site (Kd=2.1nM) designed to reduce safety concerns.
