Bolt Biotherapeutics, Inc. (Nasdaq: BOLT) today announced that updated clinical data from its Phase 1/2 dose-escalation study of BDC-1001 will be presented in a mini-oral presentation at the European Society for Medical Oncology (ESMO) Congress 2023, being held in Madrid, Spain and virtually from October 20-24, 2023.
REDWOOD CITY, Calif., Oct. 16, 2023 (GLOBE NEWSWIRE) -- Bolt Biotherapeutics, Inc. (Nasdaq: BOLT), a clinical-stage biopharmaceutical company pioneering novel immuno-oncology therapeutics for the treatment of cancer, today announced that updated clinical data from its Phase 1/2 dose-escalation study of BDC-1001 will be presented in a mini-oral presentation at the European Society for Medical Oncology (ESMO) Congress 2023, being held in Madrid, Spain and virtually from October 20-24, 2023.
BDC-1001 is an investigational Immune-Stimulating Antibody Conjugate (ISAC) in development for the treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive cancer. The ESMO presentation will include new results from the recently completed first-in-human Phase 1/2 dose-escalation study of BDC-1001 in patients with advanced HER2-expressing solid tumors.
“The upcoming presentation at ESMO builds on the positive data we presented at ASCO 2023 with additional insights into efficacy, safety, and biomarkers. These data provide further support for the recommended Phase 2 dose (RP2D) being used in the ongoing Phase 2 study of BDC-1001,” said Edith A. Perez, Chief Medical Officer of Bolt Biotherapeutics. “We are proud of the significant progress we have made with BDC-1001 and these latest data reinforce that Boltbody™ ISACs can activate a patient’s immune system to fight cancer. We continue to advance BDC-1001 through the Phase 2 clinical studies in four HER2-positive solid tumor types.”
Details about the presentation can be found below and on the ESMO website.

About BDC-1001
Bolt Biotherapeutics’ lead program, BDC-1001, is a human epidermal growth factor receptor 2 (HER2) ISAC comprising a HER2-targeting biosimilar of trastuzumab conjugated with a non-cleavable linker to a proprietary TLR7/8 agonist. Following the successful completion of the BDC-1001 dose-escalation trial for the treatment of patients with HER2-expressing solid tumors, Bolt is now conducting two Phase 2 clinical trials in the U.S., Europe, and South Korea: NCT04278144 for patients with colorectal, endometrial, and gastroesophageal cancers and NCT05954143 for patients with breast cancer.
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 reprogram the tumor microenvironment 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-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 https://www.boltbio.com/
