Bolt Biotherapeutics reports positive Phase 1 cancer trial results

REDWOOD CITY, Calif. - Bolt Biotherapeutics (NASDAQ:BOLT), a clinical-stage biopharmaceutical company with a market capitalization of $14.4 million, announced favorable results from its Phase 1 dose-escalation clinical study of BDC-3042, an immunotherapy treatment for various cancers, at the American Association for Cancer Research (AACR) Annual Meeting held in Chicago. According to InvestingPro data, the company maintains a strong liquidity position with a current ratio of 3.2x.

The trial evaluated BDC-3042 in patients with metastatic or unresectable cancers, including triple-negative breast cancer, renal cell carcinoma, colorectal cancer, melanoma, non-small cell lung cancer, and ovarian cancer. The study enrolled seventeen patients who had previously undergone an average of four lines of therapy.

As of April 7, 2025, BDC-3042 was well tolerated at doses up to 10 mg/kg every two weeks, with no dose-limiting toxicities or serious adverse events related to the drug. The most common drug-related adverse events were fatigue, flatulence, and nausea, each reported in 12% of patients.

The treatment showed biological activity, with increases in proinflammatory cytokines and chemokines, and evidence of anti-tumor activity. Notably, all non-small cell lung cancer patients (3/3) experienced stable disease for at least 12 weeks, and two out of three patients at the highest dose also showed stable disease. One non-small cell lung cancer patient had an unconfirmed partial response and remained in the study beyond 18 weeks.

The study’s results support the selection of 10 mg/kg every two weeks as the recommended Phase 2 dose. The drug demonstrated favorable pharmacokinetics, providing sufficient exposure to potentially extend the dosing interval.

Bolt Biotherapeutics is seeking a development partner to further advance BDC-3042, citing its commercial potential. The company’s pipeline includes other immunotherapy candidates, with activities underway to initiate clinical trials for BDC-4182 in the second quarter of 2025.
