Phase III Trial Comparing Capecitabine in Combination With Sorafenib or Placebo in the Treatment of Locally Advanced or Metastatic HER2-Negative Breast Cancer

Summary

The objective of this phase-III trial is to compare the efficacy and safety of sorafenib in combination with capecitabine versus capecitabine in combination with placebo in the treatment of subjects with locally advanced or metastatic HER2-negative breast cancer who are resistant to or have failed prior taxane and an anthracycline or for whom further anthracycline therapy is not indicated. After signing consent there can be up to 28 days before starting the treatment during which time a number of tests will be carried out which will include tumor evaluations and medical history. The following tests and evaluations will have to be done within 7 days of the start of treatment,on Day 1 of every cycle and at the end of study: Electrocardiogram, blood tests, patient quality of life questionnaires and a complete physical exam and vital signs. Treatment will be given in 21 day cycles with sorafenib/placebo to be taken every day for 21 days and capecitabine to be taken for the first 14 days. Patients will come in weekly for the first 6 weeks and then on Day1 for every cycle after the first 2 cycles. During the weekly visits the subjects will be check for any side effects and blood draws will happen for the study on Day 1 of each cycle. Subjects will be followed for overall survival.
