Announcement
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.
AI Summary
Bolt Biotherapeutics has updated the ongoing Phase 1 dose escalation study of BDC-4182, a next-generation Boltbody™ ISAC clinical candidate targeting claudin 18.2, a validated oncology target. At the first dose levels, patients showed a strong immune response. To build on these results, the company will revise the trial protocol to include step-up dosing, a method already used commercially with T-cell engagers. Preclinical studies of BDC-4182 support this dosing approach.
As a result of these changes, initial clinical data is now expected in the third quarter of 2026. To maintain its financial stability, Bolt will reduce its workforce by about 50%. This move is designed to extend the company’s cash runway into 2027. Bolt’s leadership said this restructuring will help focus resources on advancing BDC-4182 toward later clinical stages and on partnerships that boost long-term shareholder value.

Announcement
Bolt Biotherapeutics announced results from its Phase 1 dose-escalation clinical study of BDC-3042 at the American Association for Cancer Research (AACR) Annual Meeting, taking place April 25-30, 2025, in Chicago, Illinois.
AI Summary
Bolt Biotherapeutics announced promising results from its Phase 1 dose-escalation study of BDC-3042 at the AACR Annual Meeting in Chicago, April 25–30, 2025. The study evaluated the safety and biologic activity of this novel immunotherapy, an agonist antibody targeting dectin-2 on tumor-associated macrophages. BDC-3042 was well tolerated at doses up to 10 mg/kg administered every two weeks, with no dose-limiting toxicities or drug-related serious adverse events observed. The trial also showed clear dose-dependent increases in proinflammatory cytokines and chemokines, indicating strong immune activation. Notably, there were early signs of anti-tumor activity, including an unconfirmed partial response in one non-small cell lung cancer patient and stable disease in several others. Based on these positive findings, Bolt Biotherapeutics is now actively seeking a partner to accelerate further development and commercialization of BDC-3042.
