Bolt Biotherapeutics Inc
boltbio.comBolt Biotherapeutics (NASDAQ: BOLT) is a clinical-stage biopharmaceutical company that develops immuno-oncology therapies targeting myeloid biology. The company generates no product revenue, funding operations through equity issuances and, where available, external partnerships. Bolt was founded in 2015 based on research from the Engleman Laboratory at Stanford University. As of the 10-K filed March 12, 2026, William P. Quinn serves as President, Chief Executive Officer, and Chief Financial Officer. The company's pipeline centers on two approaches: the proprietary Boltbody ISAC (Immune-Stimulating Antibody Conjugate) platform and BDC-3042, a dectin-2 agonist antibody designed to repolarize tumor-associated macrophages from tumor-supportive to tumor-destructive states. BDC-3042 completed Phase 1 dose escalation, reporting a favorable safety profile and monotherapy anti-tumor activity in April 2025, but development is paused as of the filing date while the company seeks a partner or additional funding. The accumulated deficit position and ongoing net losses reflect a pre-commercial operation dependent on external capital.
