REDWOOD CITY, Calif., March 29, 2023 (GLOBE NEWSWIRE) -- Bolt Biotherapeutics Inc. (Nasdaq: BOLT), a clinical-stage biopharmaceutical company developing novel immunotherapies for the treatment of cancer, today reported financial results for the fourth quarter and full year ended December 31, 2022, and provided a business update.
“We believe the BDC-1001 Phase 1 results validate our Boltbody™ ISAC approach. Our design decisions enable us to deliver potent immune-stimulating antibody conjugates that can achieve positive clinical responses with acceptable tolerability, thereby, decoupling anti-tumor activity from the systemic safety issues that others have encountered. We are advancing into a thoughtfully designed, focused Phase 2 program evaluating BDC-1001 in patients with four different types of HER2-positive solid tumors where there remains important unmet medical need,” said Randall Schatzman, Ph.D., Chief Executive Officer of Bolt Biotherapeutics.
“We are pleased to be entering into an agreement with Roche to supply pertuzumab in support of a new combination study with BDC-1001 and we look forward to investigating the impact of this combination in patients with HER2-positive metastatic breast cancer, while we continue to investigate BDC-1001 as monotherapy and work with our partner Bristol Myers Squibb to explore the combination with nivolumab. The progress in developing new immunotherapies in both our proprietary and partnered research programs demonstrates the potential of myeloid biology to provide important new treatment options to patients with cancer.”
Recent Highlights and Anticipated Milestones
- Topline BDC-1001 Phase 1 dose-escalation results – Topline data from a multi-center, multi-dose Phase 1 clinical trial evaluating BDC-1001 as a single agent and in combination with nivolumab supports selection of a recommended phase 2 dose (RP2D) and initiation of a Phase 2 clinical program including two studies in four tumor types.
- Phase 2 BDC-1001 studies planned to initiate in 2023 – Clinical trials will include patients with HER2-positive breast, colorectal, endometrial, and gastroesophageal cancers at clinical sites in the U.S., multiple European countries, and South Korea evaluating BDC-1001 as monotherapy, in combination with pertuzumab, and separately, in combination with nivolumab.
- BDC-3042 to enter the clinic in 2023 – Investigational New Drug (IND)-enabling activities for a Phase 1 trial for BDC-3042 are proceeding on track. BDC-3042 is an agonistic antibody targeting Dectin-2, an immune-activating receptor expressed by TAMs in solid tumors. Preclinical studies demonstrate the ability of Dectin-2 agonistic antibodies to reprogram tumor-associated macrophages and drive anti-tumor activity.
- Continued progress with Boltbody™ ISAC collaborations – Collaborations with Genmab and Innovent developing next-generation Boltbody ISACs continue to progress. Both collaborations are exploring proprietary linker-payloads from the Boltbody ISAC platform, combining with Genmab’s proprietary bispecific antibodies in one collaboration and with Innovent’s proprietary antibodies in the other.
- Strengthened Bolt's Board of Directors with appointment of Laura Berner – In December 2022, Laura Berner joined the Bolt Board of Directors. Ms. Berner brings extensive biopharmaceutical industry experience, having executed more than 50 transactions including research collaborations and product co-development and co-promotion partnerships. She currently serves as the Chief Operating Officer at TRexBio and has held multiple leadership positions spanning corporate strategy, business development, investor relations, and law.
- Cash, cash equivalents, and marketable securities were $192.8 million as of December 31, 2022 – Cash on hand, coupled with growing collaboration revenues, is expected to fund multiple key milestones and operations through 2025.

Fourth Quarter and Full Year 2022 Financial Results
- Collaboration Revenue – Collaboration revenue was $1.4 million for the quarter and $5.7 million for the full year ended December 31, 2022, compared to $0.5 million and $1.3 million for the same quarter and year in 2021. The collaboration with Genmab exploring Boltbody ISACs using Genmab’s proprietary bispecific antibodies accounted for $4.2 million in revenue for 2022 and the collaboration with Innovent exploring Boltbody ISACs using Innovent’s proprietary antibodies accounted for $1.5 million in revenue for 2022.
- Research and Development (R&D) Expenses – R&D expenses were $16.8 million for the quarter and $73.1 million for the full year ended December 31, 2022, compared to $22.5 million and $75.7 million for the same quarter and year in 2021. The decrease in R&D expenses was due to lower manufacturing expenses related to the timing of batch production of our product candidates, offset by higher clinical expenses related to the ongoing BDC-1001 clinical trial due to increase in patient activities.
- General and Administrative (G&A) Expenses – G&A expenses were $5.6 million for the quarter and $22.9 million for the full year ended December 31, 2022, compared to $5.1 million and $18.4 million for the same quarter and year in 2021. The increase in G&A expenses was due to higher personnel-related expenses due to an increase in headcount and higher office and facility-related expenses, offset by lower consulting and professional services expenses.
- Loss from Operations – Loss from operations was $21.0 million for the quarter and $90.3 million for the full year ended December 31, 2022, compared to $27.1 million and $92.8 million for the same quarter and year in 2021.
About the Boltbody™ Immune-Stimulating Antibody Conjugate (ISAC) Platform
Bolt Biotherapeutics’ Boltbody ISAC platform unites 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 has completed a Phase 1 dose-escalation study demonstrating tolerability and early clinical efficacy, and the Company plans to initiate Phase 2 studies in 2023. Bolt Biotherapeutics is advancing BDC-3042, an agonist antibody targeting Dectin-2, through IND-enabling activities and expects 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 leveraging its ability to engineer and optimize novel applications of its Boltbody ISACs to develop multiple immuno-oncology candidates through strategic collaborations with leading biopharmaceutical companies.
