Bolt Biotherapeutics Announces Issuance of U.S. Patent for the Boltbody™ ISAC Technology and its Lead Development Candidate, BDC-1001

REDWOOD CITY, Calif., June 9, 2020 /PRNewswire/ -- Bolt Biotherapeutics, Inc., a private clinical-stage biotechnology company developing its Immune-Stimulating Antibody Conjugate (ISAC) platform technology to harness the power of the immune system to treat cancer, today announced that the U.S. Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,675,358 entitled "Antibody Adjuvant Conjugates." The patent provides protection for immunoconjugates of a piperazinyl imidazoquinoline adjuvant bound to any antibody, including Bolt's BDC-1001 ISAC embodiment.

BDC-1001 is being developed as a monotherapy for patients with HER2-expressing solid tumors. BDC-1001 is an ISAC comprised of trastuzumab conjugated to a Bolt proprietary TLR7/8 agonist payload.

Michael N. Alonso, Ph.D., scientific co-founder and vice president of immunology and pharmacology of Bolt, stated "The development of Boltbody™ ISACs is motivated by the insatiable need to translate scientific discoveries into products that will help cancer patients become survivors. This patent issuance is an important milestone that provides protection for our BDC-1001 clinical asset and our Boltbody™ ISAC technology platform. Our dedicated and talented teams will continue to aggressively build a robust patent portfolio to protect our pipeline, our platform, and our commitment to patients."

About Bolt Biotherapeutics' Immune-Stimulating Antibody Conjugate (ISAC) Platform Technology

The Boltbody™ platform consists of Immune-Stimulating Antibody Conjugates (ISAC) that harness the ability of innate immune agonists to convert cold tumors into immunologically hot tumors thereby illuminating tumors to the immune system and allowing them to be invaded by tumor killing cells. Boltbody™ ISACs have demonstrated the ability to eliminate tumors following systemic administration in preclinical models and have also led to the development of immunological memory, which is predicted to translate into more durable clinical responses for patients. The company's first Boltbody™ to enter clinical development, BDC-1001, is currently being evaluated in patients with HER2-expressing solid tumors.
