Overview
Brief Summary
This was a Phase 2, randomized, multicenter, open-label, 2-arm study to investigate the efficacy and safety of ociperlimab in combination with tislelizumab plus BAT1706, and tislelizumab plus BAT1706, as first-line treatment in participants with advanced Hepatocellular Carcinoma (HCC).

Arms & Interventions
Arm A: Ociperlimab + Tislelizumab + BAT1706
Participants received tislelizumab 200 milligrams (mg) intravenously once every 3 weeks followed by BAT1706 15 milligrams per kilogram (mg/kg) intravenously once every 3 weeks followed by ociperlimab 900 mg intravenously once every 3 weeks in 21-day treatment cycles until disease progression, unacceptable toxicity, or withdrawal for other reasons, whichever occurred first.

Outcomes
Primary Outcomes
Objective Response Rate (ORR) as Assessed by the Investigator
Time Frame: From 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 Outcomes
- Duration Of Response (DOR) as Assessed by the Investigator(From the first confirmed objective response until the first documentation of disease progression or death, whichever came first (i.e. up to 27 months))
- Time to Response (TTR) as Assessed by the Investigator(From the randomization date to the first documentation of response (up to 27 months))
- Disease Control Rate (DCR) as Assessed by the Investigator(From 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))
- Clinical Benefit Rate (CBR) as Assessed by the Investigator(From 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))
- Progression-Free Survival (PFS) as Assessed by the Investigator(From the randomization date to the date of first documentation of disease progression or death, whichever came first (i.e., up to 27 months))
- Overall Survival (OS)(From the randomization date until the date of death from any cause (up to 27 months))
- 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))
- Serum Concentrations of Ociperlimab(Predose 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))
