Experimental: Part 2 (Cohort A2): BGB-21447 Monotherapy Dose Expansion - Participants will receive BGB-21447 with up to two dose levels from Cohort A1 for further evaluation of safety and efficacy.


Treatment: Drugs: BGB-21447

Summary
Brief summary
This study is testing the safety and tolerability of BGB-21447 monotherapy in participants
with relapsed or refractory (R/R) non-Hodgkin lymphoma (NHL) and chronic lymphocytic
leukemia/small lymphocytic lymphoma (CLL/SLL). The study aims to determine the maximum
tolerated dose (MTD), maximum adminstered dose (MAD), recommended Phase 2 dose (RP2D), and
pharmacokinetic profile of the drug. Additionally, preliminary antitumor activity will be
characterized. The study is divided into 2 main parts: Part 1 "Monotherapy Dose Finding" and
Part 2 "Monotherapy Dose Expansion."
