Bolt Biotherapeutics to Present Interim Clinical Data on BDC-1001 Phase 1/2 Clinical Trial at ESMO Immuno-Oncology Congress 2021

REDWOOD CITY, Calif., Dec. 02, 2021 (GLOBE NEWSWIRE) -- Bolt Biotherapeutics, Inc. (Nasdaq: BOLT), 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, today announced that the company will be presenting interim clinical data in a virtual poster on BDC-1001, starting on December 6, 2021 in conjunction with the European Society for Medical Oncology Immuno-Oncology (ESMO I-O) Congress 2021 taking place on December 8 - 11, 2021. BDC-1001 is an immune-stimulating antibody conjugate (ISAC) comprising a HER2-targeting biosimilar of trastuzumab conjugated to a TLR7/8 agonist with a non-cleavable linker.

“The data we will be presenting at ESMO I-O includes more than 50 patients at increasing exposures and builds upon the data presented at ASCO 2021. We will be presenting additional insights into BDC-1001’s safety and tolerability profile, pharmacokinetics, tumor and serum biomarkers, and early signs of clinical activity. These interim results support continued investigation towards an optimal dosing regimen, as well as the initiation of a combination dose-escalation study with Opdivo^® by year-end,” said Edith A. Perez, M.D, Chief Medical Officer of Bolt Biotherapeutics.

The poster will be available in the e-Posters section of the conference virtual platform as of December 6 at 12 p.m. CET:

Abstract Title: Preliminary results from a phase 1/2 study of BDC-1001, a novel HER2 targeting TLR7/8 immune-stimulating antibody conjugate (ISAC), in patients (pts) with advanced HER2-expressing solid tumors
Presenter: Manish R. Sharma, M.D., Associate Director of Clinical Research, START Midwest
Presentation Number: 164P
Timing: On-Demand Access

Bolt Biotherapeutics management will host a conference call for the investment community, in conjunction with the now virtual ESMO Immuno-Oncology Congress 2021, to discuss emerging clinical data and insights from the ongoing Phase 1/2 study at 8:00 a.m. ET/5 a.m. PT on Monday, December 6, 2021.

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’s proprietary Boltbody™ Immune-stimulating Antibody Conjugates (ISACs) are designed to target tumor cells for elimination by myeloid cells, which then activates the myeloid cells to recruit the adaptive immune system in the anti-tumor response. This leads to the conversion of immunologically “cold” tumors to “hot” tumors. Bolt’s lead candidate, BDC-1001, is a Boltbody ISAC comprised of a HER2-targeting biosimilar of trastuzumab conjugated with a non-cleavable linker to one of Bolt’s proprietary TLR7/8 agonists for the treatment of patients with HER2-expressing solid tumors. Bolt is also advancing BDC-2034, a Boltbody ISAC targeting CEA, and a pipeline of other immuno-oncology products.
