REDWOOD CITY, Calif., March 31, 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 reported financial results for the fourth quarter and full year ended December 31, 2020 and provided an update on recent business highlights.

“Our upsized Initial Public Offering, which we completed in February 2021, leaves us in a strong financial position to execute on our vision of developing this new class of immuno-oncology products to help patients. We continue to enroll patients in the dose escalation part of our Phase 1/2 trial for our lead candidate, BDC-1001, for the treatment of patients with HER2-expressing solid tumors. We reported preliminary clinical results from an initial 20 patients at a data cutoff of January 29, 2021, which demonstrated 4 patients with stable disease and one patient with a confirmed partial response. We’re looking forward to completing the dose escalation and initiating both the monotherapy Phase 2 dose expansions part and the combination studies with an anti-PD-1 antibody part later in 2021,” said Randall C. Schatzman, Ph.D., Chief Executive Officer of Bolt. “We continue to progress our broader pipeline of targeted immunotherapies derived from our Boltbody ISAC platform, a novel technology that can be applied across a diverse range of tumor targets and has the potential to enable cancer patients to generate immunological memory against their own tumors. We plan to advance our second Boltbody ISAC BDC-2034, which targets the cancer antigen CEA, into the clinic in 2022.”

Recent Business Highlights and Anticipated Milestones

Upcoming Events

Fourth Quarter and Full Year 2020 Financial Results

Cash Position – Cash, cash equivalents, and marketable securities were $22.8 million as of December 31, 2020, as compared to $34.8 million as of December 31, 2019. Total cash, cash equivalents, and marketable securities at December 31, 2020 does not include total net proceeds of approximately $293.6 million from Bolt’s C-2 convertible preferred stock offering in January 2021 and its IPO in February 2021. Bolt expects its cash balance to fund operations into 2023, through achievement of key milestone for the BDC-1001 and BDC-2034 programs.

Research and Development (R&D) Expenses – R&D expenses were $14.9 million for the quarter and $40.4 million for the full year ended December 31, 2020, compared to $7.4 million and $26.0 million for the same quarter and year in 2019. The increase in R&D spending from 2019 to 2020 is due primarily to the 2020 start of Bolt’s Phase 1/2 clinical trial for BDC-1001, increased manufacturing of BDC-1001 to support the clinical trial and additional hiring.

General and Administrative (G&A) Expenses – G&A expenses were $2.1 million for the quarter and $9.1 million for the full year ended December 31, 2020, compared to $2.1 million and $5.2 million for the same quarter and year in 2019. The increase in G&A spending from 2019 to 2020 is due primarily to an increase in accounting and legal fees associated with IPO preparation and additional hiring to support operations as a public company.

Loss from Operations – Loss from operations was $16.9 million for the quarter and $49.2 million for the full year ended December 31, 2020 compared to $9.5 million and $31.0 million for the same quarter and year in 2019.

About Bolt Biotherapeutics, Inc.

Bolt Biotherapeutics, Inc. is a clinical-stage immuno-oncology company developing tumor-targeted therapies that leverage the power of the innate and adaptive immune systems. Bolt’s proprietary Boltbody Immune-stimulating Antibody Conjugate (ISAC) approach combines an antibody that targets a tumor antigen with an immune stimulant that triggers an innate and adaptive immune response in the tumor microenvironment. These systemically-delivered Boltbody ISACs are designed to target tumor cells for elimination by myeloid cells, which are then activated and 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.
