- 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

- Has known history of, or any evidence of active, non-infectious pneumonitis/interstitial lung disease.
- Has an active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
- Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
- Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.

5. Study Description
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.
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).
