Study of Regorafenib After Sorafenib in Patients With Hepatocellular Carcinoma

Inclusion Criteria:

* Histological or cytological confirmation of HCC (hepatocellular carcinoma) or non-invasive diagnosis of HCC as per American Association for the Study of Liver Diseases criteria in patients with a confirmed diagnosis of cirrhosis
* Barcelona Clinic Liver Cancer stage Category B or C that cannot benefit from treatments of established efficacy with higher priority such as resection, local ablation, chemoembolization or systemic sorafenib.
* Failure to prior treatment with sorafenib (defined as documented radiological progression according to the radiology charter). Randomization needs to be performed within 10 weeks after the last treatment with sorafenib.
* Tolerability of prior treatment with sorafenib defined as not less than 20 days at a minimum daily dose of 400 mg QD within the last 28 days prior to withdrawal.
* Liver function status Child-Pugh Class A. Child Pugh status should be calculated based on clinical findings and laboratory results during the screening period.

Local or loco-regional therapy of intrahepatic tumor lesions (e.g. surgery, radiation therapy, hepatic arterial embolization, chemoembolization, radiofrequency ablation, percutaneous ethanol injection, or cryoablation) must have been completed \>/=4 weeks before first dose of study medication. Note: patients who received sole intrahepatic intraarterial chemotherapy, without lipiodol or embolizing agents are not eligible.

* Eastern Cooperative Oncology Group Performance Status of 0 or 1.
* Adequate bone marrow, liver and renal function as assessed by the following laboratory tests conducted within 7 days before randomization.
* Glomerular filtration rate \>/= 30 ml/min/1.73 m\^2 according to the Modification of diet in renal disease study equation.
* At least one uni-dimensional measurable lesion by computed tomography (CT) scan or magnetic resonance imaging (MRI) according to RECIST (RECIST version 1.1), and modified RECIST for HCC. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, may be considered measurable if there has been demonstrated progression in the lesion.
* Life expectancy of at least 3 months.
* Women of childbearing potential and men must agree to use adequate contraception .

Exclusion Criteria :

* Sorafenib treatment within 2 weeks of randomization.
* Prior systemic treatment for HCC, except sorafenib.
* Permanent discontinuation of prior sorafenib therapy due to sorafenib related toxicity.
* Known history or symptomatic metastatic brain or meningeal tumors (head CT or MRI at screening to confirm the absence of central nervous system \[CNS\] disease if patient has symptoms suggestive or consistent with CNS disease).
* Uncontrolled hypertension (systolic blood pressure \[BP\] \> 150 mmHg or diastolic pressure \> 90 mmHg despite optimal medical management).
* Uncontrolled ascites (defined as not easily controlled with diuretic or paracentesis treatment).
* Ongoing infection \> Grade 2 according to NCI-CTCAE (National Cancer Institute - Common Terminology Criteria for Adverse Events) v. 4.0. Hepatitis B is allowed if no active replication is present. Hepatitis C is allowed if no antiviral treatment is required.
* Clinically significant bleeding NCI-CTCAE version 4.0 Grade 3 or higher within 30 days before randomization.
* Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 6 months before the start of study medication.
* Patients unable to swallow oral medications.
* Interstitial lung disease with ongoing signs and symptoms at the time of screening.
