- Preclinical Data Presentation: Boundless Bio showcased preclinical data for its lead ecDNA-directed therapy BBI-940 at the 2026 AACR Annual Meeting, indicating its potential as a first-in-class oral selective Kinesin degrader for treating intractable tumors.
- Target Discovery: The research team identified a novel Kinesin target essential for ecDNA segregation and inheritance in cancer cells but non-essential in healthy cells, laying the groundwork for developing new therapies targeting ecDNA-positive tumors.
- Clinical Trial Progress: BBI-940 is currently undergoing the first-in-human Phase 1 KOMODO-1 clinical trial for patients with advanced or metastatic ER+/HER2- breast cancer and TNBC-LAR, with preliminary results showing promising antitumor activity across multiple tumor types.
- Market Potential: With 14% to 17% of cancer patients exhibiting ecDNA amplification, the development of BBI-940 not only addresses significant unmet medical needs but also positions Boundless Bio for a strategic advantage in the competitive oncology market.

About BOLD
Boundless Bio, Inc. is a clinical-stage oncology company, which is engaged in cancer therapeutics that address the unmet need in patients with oncogene amplified tumors by targeting extrachromosomal DNA (ecDNA). Using its proprietary Spyglass platform, it identifies targets essential for ecDNA functionality in oncogene amplified cancer cells, then designs and develops small molecule drugs called ecDNA-directed therapeutic candidates (ecDTx) to inhibit those targets. The Company’s lead therapeutic candidate ecDTx, BBI-355, is an oral, selective inhibitor of checkpoint kinase 1 (CHK1), which manages ecDNA replication and transcription in cancer cells. BBI-355 demonstrated CHK1 inhibition and tumor regressions in oncogene amplified preclinical cancer models, including those enabled by ecDNA, and is being studied in a first-in-human, Phase I/II clinical trial in patients with oncogene amplified cancers. Its next program is directed at a previously undrugged kinesin target.

Boundless Bio to Present Preclinical Data on BBI-940 at AACR Annual Meeting 2026
- Clinical Data Presentation: Boundless Bio announced it will present preclinical data on its lead therapy BBI-940 at the 2026 American Association for Cancer Research Annual Meeting, targeting advanced or metastatic breast cancer patients, showcasing its potential in cancer treatment.
- FDA Application Approval: In January 2026, the U.S. FDA accepted the Investigational New Drug application for BBI-940, marking a significant advancement in the clinical development of this therapy and potentially accelerating its path to market.
- Mechanism Research Findings: Studies indicate that genetic and pharmacological degradation of Kinesin leads to ecDNA mis-segregation and depletion, thereby reducing the viability of ecDNA+ cancer cells, providing a novel therapeutic strategy for high-risk cancers.
- Strong Financial Position: As of December 31, 2025, Boundless Bio reported cash and cash equivalents totaling $107.6 million, expected to fund operations into the second half of 2028, demonstrating the company's ongoing investment capability in R&D.
