About BBO-11818BBO-11818 is a selective, orally bioavailable non-covalent inhibitor that targets KRAS in both the ON and OFF states, has high selectivity over HRAS and NRAS, and displays strong activity in KRAS-mutant preclinical models, including KRASG12Dand KRASG12V. BBO-11818 potently suppresses MAPK signaling and inhibits cell proliferation in KRAS-mutant cell lines and mouse models. BBO-11818 is currently being evaluated in the Phase 1KONQUER-101 trialin subjects with locally advanced unresectable or metastatic KRAS-mutant solid tumors.
About BBO-10203BBO-10203 is a first-in-class small molecule which breaks the protein-protein interaction between RAS and PI3Kα and inhibits RAS-mediated activation of the PI3Kα pathway. It selectively disrupts oncogenic RAS-PI3Kα signaling while sparing insulin-mediated glucose uptake, potentially maintaining efficacy with reduced risk of hyperglycemia or hyperinsulinemia. BBO-10203 is currently being evaluated in the Phase 1BREAKER-101 trialfor patients with locally advanced or metastatic HER2+ breast cancer, HR+/HER2- breast cancer, KRAS-mutant colorectal cancer, and KRAS-mutant non-small cell lung cancer.
About BBOTBBOT is a clinical-stage biopharmaceutical company advancing a next-generation pipeline of novel small molecule therapeutics targeting RAS and PI3Kα malignancies. BBOT has the goal of improving outcomes for patients with cancers driven by the two most prevalent oncogenes in human tumors. For more information, please visitwww.bbotx.comand follow us onLinkedIn.
