Bolt Biotherapeutics to Present Updates for Three Preclinical Immuno-Oncology Pipeline Programs at AACR Annual Meeting 2022
Bolt Biotherapeutics (Nasdaq: BOLT) will present three preclinical pipeline programs at the AACR Annual Meeting 2022 from April 8-13 in New Orleans. The company is focused on immuno-oncology therapeutics combining antibody precision with immune system power. Key presentations include BDC-2034, targeting CEA, expected to enter clinical development in late 2022; BDC-3042, a Dectin-2 targeting antibody anticipated for 2023; and a PD-L1-targeting ISAC. Each program shows promise in anti-tumor activity and future clinical development.

REDWOOD CITY, Calif., March 08, 2022 (GLOBE NEWSWIRE) -- Bolt Biotherapeutics (Nasdaq: BOLT), a clinical-stage biotechnology company pioneering a new class of immuno-oncology therapeutics that combine the targeting precision of antibodies with the power of both the innate and adaptive immune systems, today announced that it will present posters for three of the company’s preclinical pipeline programs at the upcoming American Association of Cancer Research (AACR) Annual Meeting 2022, being held in-person and virtually at the Ernest N. Morial Convention Center in New Orleans, LA from April 8-13, 2022.
"We are pleased to present three poster presentations at the AACR Annual Meeting that highlight the significant progress made by our research team and the depth of our expertise in myeloid biology. We are continuing to expand our Boltbody™ ISAC platform with advanced CEA- and PD-L1-targeting ISACs, both of which have the potential to provide cancer patients with new options where few treatments are currently available. We are expanding our pipeline beyond ISACs through the development of our novel myeloid modulating antibody, BDC-3042, which repolarizes tumor-associated macrophages, or TAMs, into tumor destructive macrophages via agonism of Dectin-2,” said Randall Schatzman, Ph.D., Chief Executive Officer of Bolt Biotherapeutics.
Three of Bolt Biotherapeutics’ preclinical programs will be featured in poster presentations: (1) BDC-2034, a CEA-targeting immune-stimulating antibody conjugate (ISAC) expected to enter clinical development in the second half of 2022, (2) BDC-3042, a Dectin-2-targeting, myeloid-modulating antibody anticipated to enter clinical development in 2023, and (3) a PD-L1-targeting ISAC. These posters will highlight updates on preclinical research for each of the programs, demonstrating anti-tumor activity and supporting future clinical development for all three programs.
Poster presentation sessions will be conducted in-person and available electronically on April 12 and 13 and will be published in Proceedings of the AACR. Details for each presentation can be seen below and on the AACR website.

About the Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC) Platform
ISACs are a new category of immunotherapy that combines the precision of antibody targeting with the strength of the innate and adaptive immune systems. Boltbody ISACs comprise three primary components: a tumor-targeting antibody, a non-cleavable linker, and a proprietary immune stimulant to activate the patient’s innate immune system. By initially targeting a single marker on the surface of a patient’s tumor cells, an ISAC can create a new immune response by activating and recruiting myeloid cells. The activated myeloid cells start a feed-forward loop by releasing cytokines and chemokines, chemical signals that attract other immune cells and lower the activation threshold for an immune response. This reprograms the tumor microenvironment and invokes an adaptive immune response that targets the tumor, which can lead to the conversion of immunologically “cold” tumors to “hot” tumors with the goal of durable responses for patients with cancer.
About Bolt Biotherapeutics, Inc.
Bolt Biotherapeutics, Inc. is a clinical-stage biotechnology company pioneering a new class of immuno-oncology agents that combine the targeting precision of antibodies with the power of both the innate and adaptive immune systems. Bolt Bio’s proprietary Boltbody™ Immune-stimulating Antibody Conjugates (ISACs) are designed to target tumor cells for elimination by the immune system. BDC-1001 is a HER2-targeting Boltbody ISAC in an ongoing Phase 1/2 clinical trial enrolling patients with HER2-expressing solid tumors. Bolt is also advancing BDC-2034, a Boltbody ISAC targeting CEA, and BDC-3042, an agonist antibody targeting Dectin-2. BDC-3042 is the first candidate to be advanced from the company’s myeloid modulator platform. In addition, Bolt Bio is developing new immuno-oncology Boltbody ISACs through strategic collaborations with leading biopharmaceutical companies.
