Inclusion Criteria:

* Advanced biopsy-proven HCC
* Performance status ECOG 0-1
* Patients with Child Pugh A and B cirrhosis scores

* Patients on a liver transplant waiting list may be included
* Patient must not have curative treatment options other than liver transplant
* Patient may have been treated with intrahepatic treatment (chemoembolization or intrahepatic chemotherapy) or conventional chemotherapy or sorafenib or other experimental therapies prior to study entry. There is no limit for the number of prior therapies

* At least 4 weeks must have elapsed since administration of any anti-cancer treatment.
* Other anti-cancer treatments are not permitted during this study
* Patients must be more than 18 old and must be able to understand and sign an informed consent.

Exclusion Criteria:

* Suspected or biopsy confirmed brain metastases
* Patients with hepatic cirrhosis with Child-Pugh class C
* Patients who have received a liver transplant.
* Patients who had a surgical resection of the disease and who do not have measurable disease.
* Pregnant women
* Patients who still show objective response (complete or partial response) according to the RECIST criteria due to the last anti-cancer therapy
* Patients diagnosed with another type of cancer (excluding basal cell carcinoma) during the last five last years or whose cancer diagnosed previously is not in remission
