Brief Summary:
This is a phase 2 study whose purpose is to assess the efficacy of the combination of pembrolizumab and stereotactic body radiotherapy (SBRT) in patients with advanced hepatocellular carcinoma (HCC) who have experienced disease progression after treatment with sorafenib.

Condition or disease Intervention/treatment Phase
Hepatocellular Carcinoma Drug: Pembrolizumab Radiation: Stereotactic Body Radiotherapy (SBRT) Phase 2

Detailed Description:

Pembrolizumab will be administered intravenously as a 30-minute infusion at a dose of 200 mg every 21 days, until disease progression or intolerable toxicity.

Stereotactic radiotherapy will commence on day 2 of the first cycle of pembrolizumab, and will be delivered in 5 fractions over 8-15 days in accordance with institutional protocol.

Subjects will be re-evaluated for response every 12 weeks. In addition to a baseline scan, confirmatory scans should also be obtained 4-8 weeks following initial documentation of objective response.

Response and progression will be evaluated in this study using both RECIST 1.1and (iRECIST) guideline (Seymor 2017).

Arm Intervention/treatment
Experimental: Pembrolizumab and Stereotactic Body Radiotherapy (SBRT)

Pembrolizumab, intravenously, at a dose of 200 mg, once every 3 weeks

SBRT starting Day 2 of Cycle 1 of pembrolizumab treatment, given in 5 fractions over 10-15 days.

Drug: Pembrolizumab
Pembrolizumab is a humanized monoclonal antibody (mAb) of the IgG4/kappa isotype designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2.
Other Name: KEYTRUDA

Radiation: Stereotactic Body Radiotherapy (SBRT)
SBRT involves delivery of high doses of radiation therapy in smaller fractions




Primary Outcome Measures :
  1. Overall response rate [ Time Frame: 3 years ]
    To assess the systemic efficacy of combined SBRT and pembrolizumab in subjects with advanced HCC who have experienced disease progression after previous therapy, as measured by overall response rate (ORR).


Secondary Outcome Measures :
  1. Response rate in non-irradiated tumor lesions [ Time Frame: 3 years ]
    To measure the abscopal effect that is shrinkage of untreated tumors occurs concurrently with shrinkage of tumors within the scope of the localized treatment.

  2. Progression-free survival rate [ Time Frame: 3 years ]
    To determine the progression-free survival (PFS), in subjects receiving combination treatment with pembrolizumab and SBRT for advanced HCC who have experienced disease progression after sorafenib therapy.

  3. Overall survival rate [ Time Frame: 3 years ]
    To determine the overall survival (OS) in subjects receiving combination treatment with pembrolizumab and SBRT for advanced HCC who have experienced disease progression after sorafenib therapy.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Willing and able to provide written informed consent/assent for the trial
  • Be ≥18 years of age on day of signing informed consent.
  • Have a histologically- or cytologically-confirmed diagnosis of hepatocellular carcinoma (HCC), and at least one measurable lesion.
  • Have current liver function meeting Child Pugh Class A (5-6 points), with no encephalopathy or ascites.
  • Have intrahepatic HCC amenable to stereotactic body radiotherapy (SBRT):
  • maximum 10 lesions to be treated, and
  • total tumor diameter to be treated <20 cm
  • No single liver tumor >15 cm in diameter
  • No evidence of common or main branch bile duct invasion
  • No evidence of direct tumor extension into stomach, duodenum, small bowel, large bowel or diaphragm
  • Smaller satellites of HCC or non-definite HCC need not be encompassed within SBRT volumes if needed to respect normal tissue limits.
  • Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion.
  • Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Have demonstrated disease progression, after previous treatment with sorafenib for advanced or metastatic disease, lasting a minimum of 8 week period, allowing for appropriate interruptions and dose reductions.
  • Have recovered (to ≤ grade 1) from prior toxicities related to previous treatments at the time of study enrollment, with the exception of alopecia or skin depigmentation.
  • Be tested during screening for Hepatitis B-Virus surface antigen (HbsAg) status. Patients may be included in the study if they have adequately controlled hepatitis B
  • Patients must be tested during study screening for hepatitis C virus (HCV) RNA status. Patients with chronic infection by HCV who are untreated are allowed on study. In addition, patients with successful HCV treatment are allowed as long as 4 weeks have passed between completion of HCV therapy and start of study treatment.
  • Demonstrate adequate organ function.
  • Women of child-producing potential must agree to use effective contraceptive methods prior to study entry, during study participation, and for at least 30 days after the last administration of study medication. A serum pregnancy test within 72 hours prior to the initiation of therapy will be required for women of childbearing potential. Men treated or enrolled on this trial must agree to use adequate contraception prior to and for 4 months after completion of pembrolizumab administration.
