Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - BGB-16673

Experimental: Part 1a (Monotherapy Dose Escalation) - Dose escalation in selected R/R B-Cell malignancies to inform safety, tolerability and MTD.

Experimental: Part 1b (Monotherapy Safety Expansion) - Additional participants with selected R/R B-Cell malignancies will be enrolled at selected doses to help inform the selection of the recommended phase two dose (RP2D).

Experimental: Part 1c (Additional Monotherapy Safety Expansion) - After RP2D is determined, additional safety data will be collected to confirm RP2D for participants with selected B-cell malignancies not being evaluated in Part 2

Experimental: Part 2 (Monotherapy Expansion) - The totality of the data from Part 1a, Part 1b, and Part 1c will be used to further evaluate the safety and efficacy of BGB-16673 at the recommended dose(s) for Phase 2 expansion in specific histologies.
