Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) as Assessed by the InvestigatorFrom date of randomization until the date of first documented progression or date of death from any cause, whichever came first (i.e., up to 27 months)

ORR was defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) per response evaluation criteria in solid tumors version(v) 1.1 (RECIST v1.1). Per RECIST v1.1., CR was defined as disappearance of all target 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.

Secondary Outcome Measures
NameTimeMethod
Duration Of Response (DOR) as Assessed by the InvestigatorFrom the first confirmed objective response until the first documentation of disease progression or death, whichever came first (i.e. up to 27 months)

DOR was defined as the time from the date of first documentation of a partial response (PR) or better to the date of first documentation of progressive disease or death whichever comes first, assessed based on RECIST v1.1. Median DOR was estimated using the Kaplan-Meier method. Per RECIST v1.1, PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive disease was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.

Time to Response (TTR) as Assessed by the InvestigatorFrom the randomization date to the first documentation of response (up to 27 months)

TTR was defined as the time from the randomization date to the date of first documented partial response (PR) or better by the investigator, assessed based on RECIST v1.1. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Disease Control Rate (DCR) as Assessed by the InvestigatorFrom date of randomization until the date of first documented progression or date of death from any cause, whichever came first (i.e., up to 27 months)

DCR was defined as the percentage of participants who achieve complete response (CR), partial response (PR) or stable disease (SD), assessed based on RECIST v1.1. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 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. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Clinical Benefit Rate (CBR) as Assessed by the InvestigatorFrom date of randomization until the date of first documented progression or date of death from any cause, whichever came first (i.e., up to 27 months)

CBR was defined as the percentage of participants who achieve complete response (CR), partial response (PR), or durable stable disease (stable disease defined as \>= 24 weeks). Per RECIST 1.1., CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 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.

Progression-Free Survival (PFS) as Assessed by the InvestigatorFrom the randomization date to the date of first documentation of disease progression or death, whichever came first (i.e., up to 27 months)

PFS was evaluated by the investigator according to RECIST version 1.1; and was defined as the time from the randomization date to the date of first documentation of disease progression or date of death from any cause, whichever occurred first. Median PFS was estimated using the Kaplan-Meier method. Per RECIST v 1.1, progressive disease was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.

Overall Survival (OS)From the randomization date until the date of death from any cause (up to 27 months)

OS was defined as the time from the randomization date until the date of death from any cause. Median OS was estimated using the Kaplan-Meier method.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)From the date of the first dose of study drug up to 30 days after last dose of study drug (i.e., up to 27 months)

A TEAE was defined as an adverse event (AE) that had an onset date or a worsening in severity from baseline (pretreatment) on or after the first dose of study drug(s) and up to 30 days after the last dose of study drug(s), or initiation of new anticancer therapy, whichever occurs first. AEs were graded for severity using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version (v) 5.0, where Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4 - Life-threatening consequences; and Grade 5: Death related to AE. The TEAEs leading to death in this data table exclude death due to disease under study.

Serum Concentrations of OciperlimabPredose on Day 1 of Cycles 1, 2, 5, 9 and 17; Post dose on Day 1 of Cycles 1 and 5 and Safety Follow-up Visit (i.e., up to 30 days after last dose [up to 27 months]) (each cycle duration = 21-days)

Serum samples were assayed for ociperlimab concentrations using a validated immunoassay. This outcome measure was not analyzed for Arm B as ociperlimab was not administered in Arm B.

Serum Concentrations of TislelizumabPredose on Day 1 of Cycles 1, 2, 5, 9 and 17; Post dose on Day 1 of Cycles 1 and 5 and Safety Follow-up Visit (i.e., up to 30 days after last dose [up to 27 months]) (each cycle duration = 21-days)

Serum samples were assayed for tislelizumab concentrations using a validated immunoassay.

Serum Concentrations of BAT1706Predose on Day 1 of Cycles 1, 2, 5, 9 and 17; Post dose on Day 1 of Cycles 1 and 5 and Safety Follow-up Visit (i.e., up to 30 days after last dose [up to 27 months]) (each cycle duration = 21-days)

Serum samples were assayed for BAT1706 concentrations using a validated immunoassay.

Number of Participants With Antidrug Antibodies (ADAs) to Ociperlimab, Tislelizumab, and BAT1706Up to 27 months

Serum samples were tested for the presence of ADAs to ociperlimab, tislelizumab and BAT1706 using a validated immunoassay. The analysis included: Treatment-emergent ADA: sum of treatment-boosted ADA patients and treatment-induced ADA participants as a percentage of the ADA-evaluable participants population; Treatment-boosted ADA: Baseline-positive ADA-evaluable patients with significant increases (4-fold or higher) in ADA titer after drug administration during the treatment or follow-up observation period; and Treatment-induced ADA: ADA-evaluable participants that were ADA-negative at baseline and ADA-positive after drug administration during the treatment or follow-up observation period.
