Sorafenib improved OS among patients with hepatocellular carcinoma who were hepatitis C positive but hepatitis B negative, suggesting that the beneficial effects of sorafenib may be based on hepatitis status, according to results of a meta-analysis.
“Irrespective of the mechanism, our data suggest that in future trials in HCC, particularly where sorafenib is the control arm, there should be stratification according to etiology,” Richard Jackson, BSc, MSc, from the Liverpool Cancer Trials Unit of University of Liverpool in United Kingdom, and colleagues wrote. “Etiological differences have already been considered as factors in the interpretation of clinical trials.”
The analysis included 3,256 patients with HCC treated in three randomized phase 3 clinical trials that compared sorafenib (Nexavar, Bayer) with brivanib (BMS-540215, Bristol-Myers Squibb; n = 1,155), sunitinib (Sutent, Pfizer; n = 1,070) or linifanib (ABT-869, Abbott; n = 1,031).
