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

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.
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
- 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).
- 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.
- 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.
- 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.
