Bolt Biotherapeutics Announces Issuance of U.S. Patent Covering Dectin-2-Targeting Agonist Antibodies, Including BDC-3042

REDWOOD CITY, Calif., Sept. 12, 2023 (GLOBE NEWSWIRE) -- Bolt Biotherapeutics, Inc. (Nasdaq: BOLT), a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer, announced today the issuance of the first and foundational patent covering BDC-3042. The U.S. Patent and Trademark Office (USPTO) issued U.S. Patent 11,753,474 titled “Anti-Dectin-2 Antibodies,” on September 12, 2023.

“The issuance of this patent is an important milestone in protecting the composition of matter and methods of treatment for our BDC-3042 clinical candidate,” explained Justin A. Kenkel, Ph.D., BDC-3042 co-inventor and Principal Scientist at Bolt Biotherapeutics. “This patent covers antibodies with a novel mechanism of action that leverages Dectin-2 agonism to repolarize tumor-associated macrophages into immunostimulatory, anti-tumor macrophages. We are on track to enter the clinic with BDC-3042 this year and are excited by the potential for this new approach to treat many different types of cancer.”

The claims of the patent will be valid through May 2041, excluding any patent term adjustments or extensions which may provide additional protection.

About BDC-3042

Bolt Biotherapeutics’ myeloid-modulating antibody, BDC-3042, leverages the power of myeloid cells to stimulate anti-tumor activity. BDC-3042 is an agonist antibody targeting Dectin-2, an immune-activating pattern recognition receptor expressed by tumor-associated macrophages (TAMs) which are frequently found in the tumor microenvironment. TAMs play a key role in establishing an immunosuppressive tumor microenvironment conducive to tumor survival and progression. BDC-3042 activates Dectin-2, leading to production of an array of pro-inflammatory cytokines and chemokines and repolarization of TAMs into immunostimulatory “M1” macrophages. In addition, BDC-3042 treatment induces expression of key antigen presentation machinery, which helps to expand tumor-reactive T cells and elicit anti-tumor immunity.

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-1001, a HER2-targeting Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC), BDC-3042, a myeloid-modulating antibody, and multiple Boltbody ISAC collaboration programs. BDC-1001 is currently in Phase 2 clinical development following the successful completion of a Phase 1 dose-escalation trial that demonstrated tolerability and early clinical efficacy. BDC-3042, an agonist antibody targeting Dectin-2, is expected to initiate a Phase 1 trial in the second half of 2023. In preclinical development, BDC-3042 demonstrated the ability to convert tumor-supportive macrophages to tumor-destructive macrophages. Bolt Biotherapeutics is also developing multiple Boltbody™ ISACs in strategic collaborations with leading biopharmaceutical companies. For more information, please visit /
