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.

2. Participants who have previously received a covalently-binding Bruton´s tyrosine
kinase (BTK) inhibitor (BTKi) in any line of therapy must have received treatment with
the BTK inhibitor for = 8 weeks (unless reason for discontinuation is intolerance).

3. For dose-finding and dose-expansion, participants who had previously received a
covalently-binding BTK inhibitor as monotherapy or in combination with other
anticancer agents are eligible for the study if they meet any of the following
criteria: discontinued the previous BTK inhibitor due to disease progression,
experienced disease progression after completing treatment with a BTK inhibitor or
discontinued the BTK inhibitor due to toxicity or intolerance.

4. Measurable disease by radiographic assessment or serum IgM level (WM only)

5. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 2

6. Participants enrolling in the dose finding phase of the study may be previously
treated with a BTKi or may be naïve to BTKi therapy depending on the diagnosis and
country of enrollment; participants with MCL enrolling in the expansion cohorts (Phase
2) must have been treated with a BTKi in a prior line of therapy; CLL/SLL
participants, in addition to being treated with a BTKi in a prior line of therapy,
must also have received a Bcl-2 inhibitor in a prior line of therapy as well (Phase

lymphoma, acquired immunodeficiency syndrome (AIDS)-related B-cell lymphoma, Castleman
disease, post-transplant lymphoproliferative disorders, hairy cell leukemia, germinal

system (CNS), primary cutaneous DLBCL - leg type, DLBCL associated with chronic
inflammation, primary mediastinal (thymic) large B-cell lymphoma, intravascular large
B-cell lymphoma, ALK+ large B-cell lymphoma, primary effusion lymphoma, high-grade
B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, high-grade B-cell
lymphoma - NOS, B-cell lymphoma unclassifiable with features intermediate between
DLBCL and classical Hodgkin lymphoma, or history of or currently suspected
transformation of an indolent lymphoma to an aggressive histology (except for
participants with Richter Transformation to DLBCL are eligible for Part 1a, 1c, or
