Study of the CHK1 Inhibitor BBI-355, an ecDNA-directed Therapy (ecDTx), in Subjects With Tumors With Oncogene Amplifications
About
Brief Summary
BBI-355 is an oral, potent, selective checkpoint kinase 1 (or CHK1) small molecule inhibitor in development as an ecDNA (extrachromosomal DNA) directed therapy (ecDTx). This is a first-in-human, open-label, 3-part, Phase 1/2 study to determine the safety profile and identify the maximum tolerated dose and recommended Phase 2 dose of BBI-355 administered as a single agent or in combination with select therapies.
