简要总结
This study will evaluate the safety and efficacy of pembrolizumab (MK-3475) versus placebo as adjuvant therapy in participants with hepatocellular carcinoma (HCC) and complete radiological response after surgical resection or local ablation. The primary hypotheses of this study are that adjuvant pembrolizumab is superior to placebo with respect to: 1) recurrence-free survival (RFS) as assessed by blinded independent central review (BICR); and 2) overall survival (OS).

- •Has an eligibility scan (CT of the chest, triphasic CT scan or MRI of the abdomen, and CT or MRI of the pelvis) confirming complete radiological response ≥4 weeks after complete surgical resection or local ablation. Randomization needs to occur within 12 weeks of the date of surgical resection or local ablation.
- •Has no radiologic evidence of disease prior to enrollment.
- •Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 7 days prior to Cycle 1, Day

结局指标
主要结局
Recurrence-Free Survival (RFS)
时间窗: Up to ~6 years
RFS is defined as the time from randomization to first documentation of disease recurrence (local, regional, or distant) as assessed by BICR or by pathology consistent with HCC if required per the site's standard of care, or death due to any cause (both cancer and non-cancer causes of death), whichever occurs first.
Overall Survival (OS)
时间窗: Up to ~8 years
OS is defined as the time from randomization to death due to any cause.
Recurrence-Free Survival (RFS)
时间窗: Up to approximately 69 months
RFS was defined as the time from randomization to first documentation of disease recurrence (local, regional, or distant) as assessed by blinded independent central review (BICR) or by pathology consistent with HCC if required per the site's standard of care, or death due to any cause (both cancer and non-cancer causes of death), whichever occurred first. RFS was reported for each arm.
Overall Survival (OS)
时间窗: Up to approximately 69 months
OS was defined as the time from randomization to death due to any cause. OS was reported for each arm.
