Bolt Biotherapeutics builds antibodies that carry an immune-stimulating payload into tumours so the body's own myeloid cells attack the cancer; BDC-4182 aims this at Claudin 18.2.
Bolt Biotherapeutics develops Boltbody immune-stimulating antibody conjugates (ISACs), which link a tumour-targeting antibody to a Toll-like receptor agonist that activates myeloid cells inside the tumour. Its first programme, the HER2-directed trastuzumab imbotolimod (BDC-1001), was followed by BDC-3042, a Dectin-2 agonist antibody, and BDC-4182, a Claudin 18.2 ISAC that entered the clinic for gastric and pancreatic cancers.
BDC-4182 is an experimental monoclonal antibody from Bolt Biotherapeutics in phase 2 trials for gastric & gastro-oesophageal junction cancer, aimed at Claudin 18.2.
