Bolt Biotherapeutics (BOLT) presented updated preclinical data for BDC-4182, their next-generation Boltbody™ ISAC targeting claudin 18.2, and findings from Phase 1 dose-escalation trial of BDC-1001 at SITC. BDC-4182 showed superior efficacy compared to claudin 18.2 ADCs in preclinical studies, demonstrating anti-tumor activity across various models and acceptable safety in non-human primates. The company plans to initiate clinical trials in 2025. The Phase 1 BDC-1001 trial revealed that greater immune activation was associated with clinical benefit, particularly in patients with high HER2 antigen expression, supporting the development of next-generation ISACs with enhanced immune activation.
