Brief Summary:

The study comprises a main study of pembro-treated HCC patients and a sub-study of untreated HCC patients. In the main study, patients will be treated with pembrolizumab as neoadjuvant treatment approximately 4 weeks prior scheduled surgery. Adjuvant treatment with pembrolizumab with commence at approximately 4 weeks post-surgery for up to 12 months. Subjects will be followed up for a further 12 months after end of treatment for recurrence and survival.

The sub-study is a tumour sample collection study which will provide pre-treatment immune microenvironment data from up to 15 pairs of HCC/adjuvant liver tissue samples. Translational analyses performed for liver tissue samples in the sub-study will be harmonized with the analyses on liver tissue samples collected in the main study.

Arm Intervention/treatment
Experimental: Treatment
Neoadjuvant treatment will consist of one dose of IV pembrolizumab. Tumor resection will be performed approximately 4 weeks after neoadjuvant pembrolizumab. Adjuvant treatment with pembrolizumab will be administered 4 weeks after the surgery.
Drug: Pembrolizumab
200mg of intravenous infusion every 3 weeks
Other Name: MK-3475




Primary Outcome Measures :
  1. Number of subjects with HCC recurrence [ Time Frame: 2 years after hepatic resection ]
    To evaluate the effect of neoadjuvant and adjuvant pembrolizumab on recurrence rate

  2. Number of CD8+ Ki67+ T cells found in resected tumour from subjects [ Time Frame: Up to 24 months after hepatic resection ]
    To compare the phenotype of immune cells in the tumor microenvironment after tumor resection from recurrence-free verses recurrent subjects receiving pembrolizumab

    • Albumin: ≥3.0 g/dL
    • International Normalized Ratio (INR) or Prothrombin Time (PT) AND Activated Partial Thromboplastin Time (aPTT): ≤1.5 X ULN OR within therapeutic range for subjects on anticoagulant therapy. Abnormalities will be corrected prior to liver resection, if necessary according to institution practice
  • Have Child-Pugh score ≤ 6.
  • Be scheduled for liver resection within 5-6 weeks.
  • Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
  • Female subjects of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 120 days after the last dose of study medication.
  • Male subjects of childbearing potential must agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.
  • Have a performance status of 0-1 using the ECOG Performance Scale.
  • Have not had treatment for HCV or are not on current anti-HCV treatment for subjects with chronic infection by HCV. For subjects who have had anti-HCV therapy, the last dose of anti-HCV medication should be at least 4 weeks before first dose of pembrolizumab.
  • Have HBV viral load under 100 IU/mL with or without treatment, for subjects with chronic hepatitis B infection. HBV viral load must be less than 100 IU/mL on at least 4 weeks of anti-viral therapy prior to first dose of pembrolizumab.
