Outcome Measures
Primary Outcome Measures
- Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) with adverse events leading to discontinuation, and AEs graded according NCI-CTCAE V5. [approximately 3 years]
also may be assessed using the 2018 iwCLL Guidelines for Diagnosis, Indications for Treatment, Response Assessment, and Supportive Management of CLLA. TEAE is defined as an AE that had an onset date or a worsening in severity from baseline (pretreatment) on or after the date of the first dose of the study drug and up to 30 days after the last dose of study treatment or the initiation of a new anticancer therapy, whichever is earlier
- Recommended Phase 2 Dose (RP2D) of Orally Administered BGB-16673 [approximately 3 years]
The RP2D is the maximum tolerated dose (MTD) or less. An RP2D less than the MTD may be chosen if aspects of tolerability or efficacy not encompassed by the MTD determination suggest utilizing a lower dose
Secondary Outcome Measures
- Single Dose Maximum observed plasma concentration (Cmax) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2

Collected for both Part 1 and Part 2
- Single Dose Time to reach Cmax (tmax) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Single Dose Time to reach half of Cmax (T1/2) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Single Dose Area under the plasma concentration-time curve (AUC) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Single Dose apparent total clearance of drug from plasma after oral administration (CL/F) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Single Dose apparent volume of distribution (Vz/F) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Single Dose accumulation ratios of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State Maximum observed plasma concentration (Cmax) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State minimum observed plasma concentration (Cmin) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State Time to reach Cmax (tmax) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State Time to reach half of Cmax (T1/2) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State Area under the plasma concentration-time curve (AUC) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]
Collected for both Part 1 and Part 2
- Steady State apparent total clearance of drug from plasma after oral administration (CL/F) of BGB-16673 [Day 1 pre-dose and 2, 4, 6,8,24, 48 and 72 hours post-dose (approximately 2 years)]

Collected for both Part 1 and Part 2
- BTK protein degradation in peripheral blood upon BGB-16673 monotherapy [Day 1 pre-dose and 8 hours post-dose (approximately 2 years)]
- Number of Participants with overall response rate (ORR) [approximately 3 years]
Best overall response is defined as the best response recorded from the first dose of the study drug until data cut or the initiation of a new anticancer treatment
- Number of WM Participants with major response rate (MRR) [approximately 3 years]
MRR is defined as the proportion of patients whose best overall response (BOR) is partial response (PR) or better (PR, very good partial response [VGPR], or complete response (CR)).
