Outcome Measures
Primary Outcomes (5)
Part A: The Recommended Dose for Expansion (RDFE) of BGB-10188 Monotherapy in Hematologic Malignancies
The RDFE of BGB-10188 monotherapy in participants with hematologic malignancies was planned to be determined from safety, tolerability, pharmacokinetic (PK), and any other relevant and available data based on recommendations from the Safety Monitoring Committee. Part A dose-escalation enrolled participants with R/R CLL/SLL, MZL, FL, MCL, and DLBCL up to 540 mg, however the maximum tolerated dose was not reached and the RDFE could not be determined based on the data that were collected.
Up to 28 days
Part B: The RDFE of BGB-10188 in Combination With Zanubrutinib in Hematologic Malignancies
The RDFE of BGB-10188 in combination with zanubrutinib was planned to be determined from safety, tolerability, PK, and any other relevant and available data obtained, based on recommendation of the Safety Monitoring Committee. The RDFE could not be determined since not all planned dose cohorts in this part of the study were enrolled and not enough data were collected to establish the RDFE.
Up to 28 days
Part D: The RDFE of BGB-10188 in Combination With Tislelizumab in Advanced Solid Tumors
The RDFE of BGB-10188 in combination with tislelizumab was determined based on the totality of safety, tolerability, PK, and any other relevant and available data that were obtained from the dose escalation phase for Part E.
Up to 28 days
Part E: Overall Response Rate (ORR) as Per Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1
ORR was defined as the percentage of participants who had complete response (CR) or partial response (PR). Per RECIST v.1.1., CR was defined as disappearance of all target lesions, non-target lesions and no new lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<) 10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
Up to 10.0 months
Number of Participants With Treatment Emergent Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs Leading to Discontinuation
An AE was defined as any unfavorable and unintended sign, symptom, or disease associated with the use of study drugs, whether considered related to study drugs or not. An SAE was any untoward medical occurrence that, at any dose, resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability, was a congenital anomaly or was considered a medically significant. TEAE was an AE that has an onset date or a worsening in severity from baseline on or after the first dose of study drug. Severity of AEs was assessed according to National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTCAE) v.5.0, which consists of: Grade 1 Mild; Grade 2 Moderate; Grade 3: Severe; Grade 4: Life-threatening; Grade 5: Death due to AE.
Part A: 47.2 Months; Part B: 24 Months; Part D: 15.2 Months; Part E: 10 Months
