“At Bolt, we set a high bar for advancing our programs, and while BDC-1001 provided clinical validation for the ISAC mechanism, it did not meet our high bar for advancement. With limited resources, we want to focus those resources on the best product candidates. Our Boltbody™ ISAC technology platform continues to improve and our next-gen ISACs have outperformed cytotoxic ADCs in our preclinical studies. The increased activity of the next-gen Boltbody™ ISACs is opening the door to tumor targets with lower expression, while maintaining design choices that prioritize safety. With this in mind, we have decided to discontinue all BDC-1001 development and focus resources on BDC-3042 and BDC-4182, our next-gen ISAC targeting the clinically validated cancer antigen Claudin 18.2,” said Willie Quinn, Chief Executive Officer. “We believe that BDC-3042, a first-in-class agonist antibody that reawakens myeloid cells to attack tumor cells, has broad potential across many tumor types. We’ve seen encouraging safety to date in our Phase 1 dose escalation study of BDC-3042 and are excited about the very strong preclinical data for BDC-4182. We believe focusing on these programs will deliver significant value to shareholders. In conjunction, we are streamlining our operations to align resources and extend our cash runway to support these programs through key value inflection points.”
