A Phase III Randomized, Double Blind, Placebo-controlled Trial Comparing Capecitabine Plus Sorafenib Versus Capecitabine Plus Placebo in the Treatment of Locally Advanced or Metastatic HER2-Negative Breast Cancer
In Brief
A Phase 3 clinical trial evaluating Sorafenib (Nexavar, BAY43-9006), Placebo, and 1 other intervention for Breast Cancer. Completed, enrolled 537 participants across 153 sites in 23 countries.
Detailed 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.

Interventions
Capecitabine was administered orally at a dose of 1,000 milligram per square meter (mg/m\^2) twice daily (12 hours apart) on Days 1 through 14 of each 21-day cycle. Sorafenib was administered orally at a dose of 600 mg (200 mg in the morning, 400 mg in the evening) daily, continuously (that is, Days 1 to 21, inclusive). A treatment cycle consisted of 21 days. If tolerability criteria were met for a subject, capecitabine dose was escalated to 1,250 mg/m\^2 twice daily and sorafenib dose to a total daily dose of 800 mg for that subject.
Capecitabine was administered orally at a dose of 1,000 mg/m\^2 twice daily (12 hours apart) on Days 1 through 14 of each 21-day cycle. Placebo matching to sorafenib was administered orally, 3 tablets (1 tablet in the morning, 2 tablets in the evening) daily, continuously (that is, Days 1 to 21, inclusive). A treatment cycle consisted of 21 days. If tolerability criteria were met for a subject, capecitabine dose was escalated to 1,250 mg/m\^2 twice daily and placebo dose to a total daily dose of 4 tablets (2 tablets twice daily) for that subject.
