At ASCO 2007, results from the SHARP trial were presented, which showed efficacy of sorafenib in hepatocellular carcinoma. The primary endpoint was median overall survival, which showed a 44% improvement in patients who received sorafenib compared to placebo (hazard ratio 0.69; 95% CI, 0.55 to 0.87; p=0.0001). Both median survival and time to progression showed 3-month improvements; however, there was no significant difference in median time to symptomatic progression ("p"=0.77). There was no difference in quality of life measures, possibly attributable to toxicity of sorafenib or symptoms related to underlying progression of liver disease. Of note, this trial only included patients with Child-Pugh Class A (i.e. mildest) cirrhosis. Because of this trial Sorafenib obtained FDA approval for the treatment of advanced hepatocellular carcinoma in November 2007.
