About Boundless Bio

Boundless Bio is a clinical-stage oncology company dedicated to unlocking a new paradigm in cancer therapeutics that addresses the significant unmet need in patients with oncogene amplified tumors. Boundless Bio’s research focuses on extrachromosomal DNA (ecDNA), a root cause of oncogene amplification observed in 14% to 17% of cancer patients. Boundless Bio is developing the first ecDNA-directed therapeutic candidates (ecDTx), BBI-355, an oral, selective inhibitor of checkpoint kinase 1 (CHK1), and BBI-825, an oral, selective inhibitor of ribonucleotide reductase (RNR). These compounds are being evaluated in combination in patients with oncogene amplified cancers in the Company’s phase 1/2 POTENTIATE clinical trial. Boundless Bio is conducting IND-enabling studies of another ecDTx, BBI-940, a potentially first-in-class orally bioavailable, selective Kinesin degrader. Boundless Bio is headquartered in San Diego, CA.
