Exhibit 99.1
Bolt Biotherapeutics Reports Fourth Quarter and Full-Year 2024 Financial Results and Provides Business Update
REDWOOD CITY, CA, Mar. 24, 2025 – Bolt Biotherapeutics (Nasdaq: BOLT), a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer, today reported financial results for the third quarter ended December 31, 2024, and provided a business update.
“2024 was a transformational year for Bolt as we focused the company on efficient development of the programs that could be most impactful for patients,” said Willie Quinn, Chief Executive Officer. “BDC-4182, our next-generation ISAC, is poised to enter the clinic in the second quarter. As the only ISAC targeting the validated tumor target claudin 18.2, we believe that BDC-4182 has the potential to offer a better option for patients with stomach and other claudin 18.2-expressing cancers. We are particularly excited about BDC-4182 as validation for our Boltbody ISAC approach. We’ve also completed enrollment and have cleared the DLT window for the highest dose level in the BDC-3042 Phase 1 dose escalation trial and will provide a data update next quarter at a medical meeting. BDC-3042 is our first-in-class dectin-2 agonist, and has potential across a broad range of solid tumors with high unmet medical need.”
Recent Highlights and Anticipated Milestones
Fourth Quarter and Full Year 2024 Financial Results
About the Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC) Platform Bolt Biotherapeutics’ Boltbody ISAC platform harnesses the precision of antibodies with the power of the innate and adaptive immune system to generate a productive anti-cancer response. Each Boltbody ISAC candidate comprises a tumor-targeting antibody, a non-cleavable linker, and a proprietary immune stimulant. The antibody is designed to target one or more markers on the surface of a tumor cell and the immune stimulant is designed to recruit and activate myeloid cells. Activated myeloid cells initiate a positive feedback loop by releasing cytokines and chemokines, chemical signals that attract other immune cells and lower the activation threshold for an immune response. This increases the population of activated immune system cells in the tumor microenvironment and promotes a robust immune response with the goal of generating durable therapeutic responses for patients with cancer.
About Bolt Biotherapeutics, Inc.
Bolt Biotherapeutics is a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer. Bolt Biotherapeutics’ pipeline candidates are built on the Company’s deep expertise in myeloid biology and cancer drug development. The Company’s pipeline includes BDC-3042, a first-in-class agonist antibody that activates macrophages by targeting dectin-2, and BDC-4182, a next-generation Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC) clinical candidate targeting claudin 18.2. BDC-3042 is currently in a Phase 1 dose escalation trial that includes patients with any of seven different solid tumor types. BDC-4182 is supported by strong in vitro and in vivo data demonstrating potent anti-tumor activity, and activities are underway to support the initiation of clinical trials in the second quarter of 2025. Bolt Biotherapeutics is also developing additional Boltbody™ ISACs in strategic collaborations with leading biopharmaceutical companies. For more information, please visit https://www.boltbio.com/.

In some cases, you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “on track,” “plan,” “potential,” “predict,” “project,” “should,” “will,” or “would,” or the negative of these words or other similar terms or expressions.

Forward-looking statements represent our current beliefs, estimates and assumptions only as of the date of this press release and information contained in this press release should not be relied upon as representing our estimates as of any subsequent date. These statements, and related risks, uncertainties, factors and assumptions, include, but are not limited to: the potential product candidates that we develop may not progress through clinical development or receive required regulatory approvals within expected timelines or at all; clinical trials may not confirm any safety, potency or other product characteristics described or assumed in this press release; such product candidates may not be beneficial to patients or become commercialized; and our ability to maintain our current collaborations and establish further collaborations. These risks are not exhaustive. Except as required by law, we assume no obligation to update these forward-looking statements, or to update the reasons actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future.
