This study will have 3 cohorts for determining a monotherapy MTD and ramp-up schedule: Cohort A, participants with relapsed/refractory B-cell non-Hodgkin lymphoma (R/R NHL); Cohort B, participants with R/R chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with low tumor burden; Cohort C, participants with R/R CLL/SLL with high tumor burden.
The purpose of this study is to evaluate the safety and tolerability of BGB-11417 monotherapy, define the maximum tolerated dose (MTD) or maximum administered dose and the recommended Phase 2 dose (RP2D) of BGB-11417 monotherapy for the selected B-cell malignancy dose finding cohorts, and evaluate the safety and tolerability of the ramp-up dosing schedule in the evaluated disease types.
