Bolt Biotherapeutics announced an update on the ongoing Phase 1 dose escalation study of BDC-4182, a next-generation Boltbody?? ISAC clinical candidate targeting claudin 18.2, a clinically validated target in oncology. A strong immune response was observed at the initial dose levels and the Company is in the process of modifying the clinical trial protocol to allow for step-up dosing, which has been successfully used commercially for T-cell engagers.

BDC-4182 preclinical data supports this approach. As a result of the update to the clinical trial protocol for BDC-4182, Bolt now expects to report initial clinical data in the third quarter of 2026. To conserve capital and maintain long-term shareholder value, the Company is implementing a workforce reduction of approximately 50%, extending its cash runway into 2027.
