Bolt Biotherapeutics, Inc. is a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer. The Company's pipeline candidates are built on its expertise in myeloid biology and cancer drug development. Its pipeline includes trastuzumab imbotolimod (formerly BDC-1001), a human epidermal growth factor receptor 2 - targeting Boltbody Immune-Stimulating Antibody Conjugate (ISAC), BDC-3042, a myeloid-modulating antibody, and multiple Boltbody ISAC collaboration programs. Trastuzumab imbotolimod is in Phase 2 clinical. BDC-3042, an agonist antibody targeting Dectin-2, is in a Phase 1 dose-escalation trial. In preclinical development, BDC-3042 demonstrated the ability to convert tumor-supportive macrophages to tumor-destructive macrophages. It developed a lead agonist antibody that binds to Dectin-2 and activates human tumor-associated macrophages. It is developing multiple Boltbody ISACs in strategic collaborations with biopharmaceutical companies.
