Bolt Biotherapeutics has unveiled promising preclinical results for its next-generation Boltbody™ ISACs targeting CEA and PD-L1 at the AACR Annual Meeting 2025. The company's CEA-targeted ISAC demonstrated complete responses in mice and showed good tolerance in non-human primates (NHPs) up to 15 mg/kg.
The CEA ISAC features a novel human antibody that targets CEACAM-5, commonly found in gastrointestinal cancers. Key findings include enhanced phagocytosis of CEA-positive tumor cells and stimulation of immune-activating cytokines.
The PD-L1 ISAC showed remarkable results by:
- Directly activating and reprogramming PD-L1-expressing myeloid cells
- Achieving complete regressions in models resistant to conventional treatments
- Demonstrating favorable safety profiles in NHP studies
Both ISACs showed potential for durable responses through immunological memory, supporting their use in combination with standard-of-care therapies.
