| Sep 2025 | Undisclosed stage | - | $30M | Crossbow Therapeutics is a Cambridge, MA-based biotechnology company developing TCR-mimetic antibody therapies under its T-Bolt platform to target peptide-human leukocyte antigen (pHLA) complexes on cancer cells, addressing a broad range of hematologic and solid tumors previously out of reach for antibody therapies. The company's lead candidate, CBX-250, is a first-in-class T-cell engager for myeloid malignancies including acute myeloid leukemia, chronic myeloid leukemia, myelodysplastic syndromes, and chronic myelomonocytic leukemia, currently in the Phase 1 CROSSCHECK-001 trial with data expected end of 2026. CBX-663 targets telomerase reverse transcriptase-derived pHLA for hematologic and solid tumors, with an IND submission and Phase 1 trial planned for Q3 2026. An initial SEC filing on September 30, 2025, reported raising $30.3 million from an offering of $80 million. This was followed by a $77 million Series B financing announced in March 2026, co-led by Taiho Ventures and Arkin Bio Capital, with participation from new investors Sixty Degree Capital, Hamilton Square Partners Management LP, LifeLink Ventures, Libbs Ventures, and Blood Cancer United’s Therapy Acceleration Program, plus existing investors MPM BioImpact, Pfizer Ventures, BVF Partners, Polaris Partners, Eli Lilly and Company, and Mirae Asset Venture Investment. Taiho Ventures President Sakae Asanuma and Arkin Bio Capital Managing Partner Pini Orbach joined the board. Proceeds from the Series B will fund completion of the CBX-250 Phase 1 trial, advance CBX-663 toward clinical testing, and expand the T-Bolt pipeline. Crossbow, incubated at MPM BioImpact, launched in 2023 with $80 million in Series A funding and is led by CEO Briggs Morrison, M.D., former CMO at AstraZeneca with experience at Pfizer, Merck, and Syndax Pharmaceuticals. Preclinical and translational data on CBX-250 and CBX-663 will be presented at the AACR 2026 Annual Meeting in April. |
| Jul 2023 | Series A | MPM Capital (lead); Pfizer Venture Investments (lead); Polaris Partners; Biotechnology Value Fund; Eli Lilly; Mirae Asset Venture Investment; Mirae Asset Capital | $80M | Crossbow Therapeutics is a Cambridge, Massachusetts-based biotechnology company focused on developing a novel class of antibody therapies to treat cancer using its proprietary T-Bolt technology, which uses T-cell receptor (TCR)-mimetic antibodies to target peptide human leukocyte antigen (pHLA) on cancer cells. The company was founded by industry veterans including Briggs Morrison as Chief Executive Officer (formerly Chief Medical Officer at AstraZeneca) and Dmitri Wiederschain as Chief Scientific Officer. On July 11, 2023, Crossbow closed an $80 million Series A financing round at a post-money valuation of $112.5 million. The round was co-led by MPM BioImpact and Pfizer Ventures, with participation from Polaris Partners, BVF Partners, Eli Lilly and Company, Mirae Asset Venture Investment, and Mirae Asset Capital. The company issued 61,538,462 Series A preferred shares at $1.30 per share for gross proceeds of $80 million. Crossbow's primary development focus is CBX-250, a T-cell engager (TCE) designed to target myeloid cancer cells, with a phase 1 trial readout expected at the end of 2026. The company is enrolling patients with acute myeloid leukemia, chronic myeloid leukemia, myelodysplastic syndromes, and chronic myelomonocytic leukemia. A second therapy, CBX-663, targeting telomerase reverse transcriptase-derived pHLA, was planned to enter phase 1 development in the third quarter of 2023. As a newly launched biotech company at the time of its Series A, Crossbow had no reported revenue or EBITDA metrics. The financing enabled the company to advance its TCR-mimetic immunotherapy pipeline, which it positioned as capable of targeting the entire universe of cancer antigens and addressing limitations of current cancer treatments. |
