The company went IPO on 2024-03-28. Boundless Bio, Inc. is a clinical-stage oncology company, which is engaged in cancer therapeutics that addresses 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. Its lead 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 ecDNA-enabled preclinical cancer models and is being studied in a first-in-human, Phase I/II clinical trial in patients with oncogene amplified cancers. Its second ecDTx, BBI-825, is an oral, selective inhibitor of ribonucleotide reductase, which is essential for ecDNA assembly and repair in cancer cells.
