The anti-HER2 biparatopic antibody (bpAb) KJ-015 was rationally designed at Shanghai Bao Pharmaceuticals Co. Ltd. by leveraging published antibody-antigen structures to share common light chain with two Fab arms, resulting in functionally balanced high affinity for two HER2 nonoverlapping epitopes.
Poseida Therapeutics Inc. has announced the nomination of a new development candidate under its collaboration with F. Hoffmann-La Roche Ltd., triggering a milestone payment from Roche to Poseida.
Chimeric antigen receptor (CAR) T-cell therapies (CAR T) have proven effective in several hematological cancers and are advancing across the pipelines of other types of tumors with limited efficacy, such as in the more complex environment of solid tumors.
Claudin-6 (CLDN6) is a tight junction protein that has been found to be up-regulated in around 20 different types of cancer, among them ovarian, endometrial and germ cell tumors. Conventional T-cell engagers (TCEs), although effective, may be improved with costimulation to overcome T-cell exhaustion due to CDE3 stimulation alone.
In recent years, immune checkpoint inhibitors have had great success in the treatment of advanced cancers, but often, they are only effective in a minority of patients. Researchers from Weill Cornell Medicine have discovered that the activation of the pentose phosphate pathway (PPP) in combination with standard immune checkpoint inhibitors resulted in enhanced antitumor efficacy both in vitro and in vivo.
Westlake Therapeutics (Hangzhou) Co. Ltd. and affiliated organizations have reported the design and preclinical characterization of novel erythrocytes conjugated to major histocompatibility complex (MHC) class I (MHC-I) protein, being developed for the treatment of cancer.
Researchers from Shanghai Institute of Biological Products Co. Ltd. published details on the development and preclinical characterization of novel CD20-targeting T cell-dependent bispecific Fab-FabCH3 antibodies, referred to as tandem antigen-binding fragment 002 (TFAB-002).
Ono Pharmaceutical Co. Ltd. has entered into a license agreement with Ligachem Biosciences Inc. for LCB-97, a preclinical stage antibody-drug conjugate (ADC) for solid tumors.
