According to initial results presented this week at the 2015 Genitourinary Cancers Symposium in Orlando, Florida, the use of either Nexavar (sorafenib) or Sutent (sunitinib) provide no benefit to patients with locally advanced renal cell carcinoma who are at a high risk of recurrence.
The phase 3 trial conducted by the ECOG-ACRIN Cancer Research Group is the first and largest study reporting on the efficacy of sunitinib or sorafenib in patients who have undergone surgery to remove the kidney tumor.
"Unfortunately we found that the use of sunitinib or sorafenib in this setting did not reduce the incidence of recurrence as compared to standard care," said lead researcher Naomi B. Haas, MD, from the University of Pennsylvania's Abramson Cancer Center in Philadelphia.
For the international, phase III study, researchers enrolled 1,943 patients considered at high risk for recurrence following surgery to remove a kidney tumor and randomly assigned them to receive sorafenib, sunitinib, or placebo for 1 year.
Results of the study showed a median progression-free survival of 5.6 years for those treated with sunitinib compared with 5.6 years for those treated with sorafenib and 5.7 years for those who received placebo.
Research results highlighted today at the press conference of a major medical meeting report no benefit from the use of either Sutent (sunitinib) or Nexavar (sorafenib) among patients with locally advanced renal cell carcinoma at high risk of recurrence.
