Sichuan Kelun-Biotech Biopharmaceutical Co. Ltd. has described Toll-like receptor 7 (TLR7) and/or TLR8 agonists and their immunostimulatory antibody conjugates (ISACs) consisting of antibodies covalently linked to TLR7 and/or TLR8 agonists through cleavable or uncleavable linkers.
The overexpression of transferrin receptor 1 (TfR1) has been reported in several cancer types but is also expressed in normal cell types such as erythroblasts. On the other hand, epidermal growth factor receptor (EGFR) is highly expressed in epithelial carcinomas.
A team from GC Cell Corp. reported preclinical data on GL-205, a novel allogeneic anti-CD5 CAR-NK being developed for the treatment of T-cell malignancies. GL-205 was developed using cord blood-derived NK cells that were genetically modified to express CD5-directed CAR and simultaneously produce IL-15 to support NK cell survival and proliferation.
Researchers from Beigene (Beijing) Co. Ltd. have disclosed preclinical data for BGB-B167, a first-in-class immunoglobulin G (IgG)-based bispecific antibody (bsAb) targeting 4-1BB and CEA, being developed for the treatment of advanced or metastatic solid tumors.
The U.S. FDA has cleared Biocity Biopharma Co. Ltd.’s IND application for a phase I study of BC-2027. This is the company’s second first-in-class antibody-drug conjugate (ADC) to be approved for clinical trials, following BC-3195, which is directed against placental-cadherin (CDH3).
DXC-006 (Hangzhou DAC Biotechnology Co. Ltd.) is an antibody-drug conjugate (ADC) that targets CD56, a molecule involved in cell-cell adhesion and cell-matrix adhesion that is overexpressed in neuroblastoma, small-cell lung cancer and multiple myeloma, but less frequently expressed in normal tissues. DXC-006 consists of an anti-CD56 antibody (DXA-006) linked to the topoisomerase 1 (TOP1) inhibitor CPT-116 through a linker.
At the AACR meeting, Innovent Biologics Inc. discussed the discovery and preclinical evaluation of a B7-H3/EGFR bispecific antibody-drug conjugate (bsADC).
It has been previously demonstrated that B7-H3 and EGFR are co-expressed in multiple solid tumors. At the ongoing AACR meeting in San Diego, researchers from Innovent Biologics Inc. presented preclinical data for their bispecific antibody (bsAb), IBI-334, against B7-H3 and EGFR.
Caris Discovery, the therapeutic research arm of Caris Life Sciences Inc., has established a multiyear strategic partnership with Merck KGaA to accelerate the discovery and development of first-in-class antibody-drug conjugates for cancer patients.
