Bolt Biotherapeutics Secures U.S. Patent for Game-Changing Dectin-2-Targeting Agonist Antibodies, with a Spotlight on BDC-3042

In a groundbreaking development, Bolt Biotherapeutics, Inc. (Nasdaq: BOLT), a visionary player in the field of cancer immunotherapy, has just achieved a significant milestone. The company proudly announced the issuance of a pioneering patent that serves as the bedrock for BDC-3042, its groundbreaking clinical candidate.

This game-changing patent, officially designated as U.S. Patent 11,753,474 and titled “Anti-Dectin-2 Antibodies,” was granted by the U.S. Patent and Trademark Office (USPTO) on September 12, 2023. This achievement marks a pivotal moment in safeguarding the composition of matter and the innovative treatment methodologies associated with BDC-3042.

Explaining the significance of this milestone, Dr. Justin A. Kenkel, Co-inventor of BDC-3042 and Principal Scientist at Bolt Biotherapeutics, stated, “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. 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.”

Notably, the patent’s claims are expected to remain valid until May 2041, barring any patent term adjustments or extensions that may further enhance its protective scope.

About BDC-3042

Bolt Biotherapeutics’ revolutionary myeloid-modulating antibody, BDC-3042, is on a mission to harness the incredible potential of myeloid cells, supercharging their anti-tumor capabilities. BDC-3042 is a remarkable agonist antibody with its sights set on Dectin-2, a potent immune-boosting pattern recognition receptor proudly displayed by tumor-associated macrophages (TAMs) dwelling within the tumor microenvironment.

These TAMs, often found in the heart of the tumor’s lair, have long played a pivotal role in crafting an immune-suppressed environment that allows tumors to thrive and flourish. However, here’s where BDC-3042 steps in and changes the game. By activating Dectin-2, it triggers a cascade of events within these TAMs, causing them to undergo a spectacular transformation into immunostimulatory “M1” macrophages.

But that’s not all; BDC-3042’s influence extends even further. It kickstarts the production of a diverse array of pro-inflammatory cytokines and chemokines, setting off a domino effect that awakens the immune system. Furthermore, this superhero antibody doesn’t stop there—it also encourages the expression of critical antigen presentation machinery. This, in turn, paves the way for the expansion of tumor-reactive T cells, sparking a formidable anti-tumor immune response.

In essence, BDC-3042 is a catalyst for unleashing the full potential of the body’s immune system, turning the tide against cancer in a way that’s as fascinating as it is promising.

About Bolt Biotherapeutics, Inc.

At Bolt Biotherapeutics, we’re not just another clinical-stage biopharmaceutical company—we’re pioneers on a mission to rewrite the story of cancer treatment. Our journey is guided by an unparalleled understanding of myeloid biology and a relentless commitment to reshaping the landscape of cancer therapeutics.

Our impressive pipeline reads like a roster of superheroes in the fight against cancer. Leading the charge is BDC-1001, a formidable HER2-targeting Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC) that’s already carving its path through Phase 2 clinical development. Backed by the success of a Phase 1 dose-escalation trial, BDC-1001 has not only proven its tolerability but also showcased early clinical efficacy that holds immense promise.

Joining the ranks is BDC-3042, our myeloid-modulating antibody with the potential to revolutionize cancer treatment. This trailblazing antibody, set to enter Phase 1 trials in the latter half of 2023, has already demonstrated its remarkable ability to transform tumor-supportive macrophages into tumor-destroying champions.

But that’s not all; we’re not fighting this battle alone. In strategic collaborations with top-tier biopharmaceutical companies, we’re developing a legion of Boltbody™ ISACs, each with its own unique powers and potential to redefine cancer therapy.

At Bolt Biotherapeutics, we’re not just developing drugs; we’re crafting a new era of hope and possibility for cancer patients worldwide.
