Study Endpoints

Primary Endpoints

Overall Response Rate
Response was assessed every 6 weeks for the first 9 months and every 12 weeks thereafter; maximum time on follow-up was up to 13.5 months

Overall response rate (ORR) is defined as the percentage of participants with best overall response (BOR) of a confirmed complete response (CR) or partial response (PR) as assessed by the investigators per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v)1.1. CR is defined as: * Disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to \< 10 mm. * Disappearance of all nontarget lesions and normalization of tumor marker level. All lymph nodes must be nonpathological in size (\< 10 mm short axis). * No new lesions. PR is defined as: * At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. * Non-progressive disease with regard to non-target lesions, persistence of 1 or more nontarget lesion(s) and/or maintenance of tumor marker level above the normal limits. * No new lesions.

Overall Response Rate (ORR) as Assessed by the Investigator
Up to approximately 26 months

ORR is defined as the percentage of participants who had confirmed complete response Complete Response (CR) or Partial Response (PR)

Phase 1a: Number of Participants Experiencing Adverse Events (AEs)
Up to 90 days after the last dose of study drug(s) regardless of whether the participant starts a subsequent anticancer therapy
Phase 1a: Number of Participants Experiencing Serious Adverse Events (SAEs)
Up to 90 days after the last dose of study drug(s) regardless of whether the participant starts a subsequent anticancer therapy
Phase 1a: Number of Participants Experiencing AEs meeting protocol defined Dose-Limiting Toxicity (DLT) criteria
Up to 90 days after the last dose of study drug(s) regardless of whether the participant starts a subsequent anticancer therapy
Phase 1a: Maximum Tolerated Dose (MTD) of BGB-A445
Up to 30 days after the last dose of study drug(s) or before the initiation of a new anticancer treatment, whichever occurs first

The MTD is defined as the highest dose evaluated for which the estimated toxicity rate is closest to the target toxicity rate of 30%

Phase 1b: RP2D of BGB-A445 when Administered Alone
Up to 30 days after the last dose of study drug(s) or before the initiation of a new anticancer treatment, whichever occurs first
Phase 1b: Overall Response Rate (ORR) as Assessed by the Investigator
Up to 30 days after the last dose of study drug(s) or before the initiation of a new anticancer treatment, whichever occurs first

ORR is defined as the proportion of participants who had confirmed complete response Complete Response (CR) or Partial Response (PR)

Secondary Endpoints

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
From first dose of study drug to 30 days after last dose. Maximum time on treatment was 11.2 months
Duration of Response (DOR)
From first dose to the end of study; maximum time on follow-up was up to 13.5 months.
Disease Control Rate (DCR)
From first dose to the end of study; maximum time on follow-up was up to 13.5 months
