sorafenib with capecitabine for patients with measurable hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma

Summary: this research study will evaluate sorafenib (nexavar®) and capecitabine (xeloda®) to see the following: * how effective this combination of study drugs will be in treating hcc * how long subjects respond to these study drugs * what types of side effects can be expected, and * how severe the side effects are all subjects in this study will receive: * sorafenib twice a day by mouth * capecitabine twice a day by mouth treatment will be given in a 28-day treatment cycle. subjects will take sorafenib every day of the cycle. subjects will take capecitabine on days 1-7 and 15-21 of the cycle

hepatocellular carcinoma (hcc), also known as primary liver cancer, is the most common form of liver cancer and is responsible for 80 percent of the primary malignant liver tumors in adults. it is the fifth most common cancer in the world. hcc disproportionately affects men, with four times as many men developing the disease as women. in 2002, approximately 626,000 cases of hcc were reported worldwide (15,000 in the united states and 53,600 in europe), and more than 600,000 deaths (about 13,000 americans and 57,000 europeans) due to hcc were reported. the five-year relative survival rate is about seven percent. the gem-ox regimen has been used in the treatment of pancreatic cancer with encouraging results. preliminary results of the gem-ox combination have been encouraging as well.based on these observations the possibility of adding bevacizumab, a monoclonal antibody against vegf, is being studied by other investigators. however, the combination of gem-ox with bevacizumab is unlikely to be tolerated by hcc patients with child-pugh class b and c liver cirrhosis especially those with significant thrombocytopenia.it would seem therefore that the agents that could be tolerated by cirrhotic patients with advanced hcc would include capecitabine, erlotinib and sorafenib. we propose this phase ii trial of sorafenib + capecitabine combination in patients with hcc and advanced liver cirrhosis who have a platelet count of ≥ 40,000 and a child-pugh (c-p) class a-and b liver cirrhosis with a life expectancy of ≥16 weeks.
