- Registration Number
- NCT00096434
- Lead Sponsor
- National Cancer Institute (NCI)
- Brief Summary
This phase II trial is studying how well sorafenib works in treating patients with metastatic breast cancer. Sorafenib may stop the growth of tumor cells by blocking the enzymes necessary for their growth and by stopping blood flow to the tumor.
- Detailed Description
OBJECTIVES:
I. Determine the tumor response rate in patients with metastatic breast cancer previously treated with an anthracycline- and/or taxane-containing regimen receiving sorafenib.
II. Assess the toxicity profile of this drug in these patients. III. Determine time to disease progression and survival time of patients treated with this drug.
IV. Correlate pre-treatment levels of activated ERK1/2 with tumor response in patients treated with this drug.
OUTLINE: This is a multicenter study.
Patients receive oral sorafenib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Patients are followed every 6 months until disease progression and then every 3 months for up to 5 years.

Group Intervention Description Arm I sorafenib tosylate Patients receive oral sorafenib twice daily on days 1-28.

Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Primary Outcome Measures
Name Time Method Proportion of confirmed tumor responses, graded according to RECIST criteria Up to 5 years A confirmed tumor response is defined to be either a CR or PR noted as the objective status on 2 consecutive evaluations at least 4 weeks apart. The tumor response rate is defined as the total number of eligible patients who achieved a complete or partial response according to the RECIST criteria divided by the total number of eligible patients enrolled on study. A 90% confidence interval for the true response rate will be constructed using the Duffy-Santner approach.
- Secondary Outcome Measures
Name Time Method Survival time Time from registration to death, assessed up to 5 years Estimated using the Kaplan-Meier method.
Time to progression Time from registration to disease progression, assessed up to 5 years Estimated using the Kaplan-Meier method.
Incidence of adverse events, graded according to the NCI-CTC version 3 Up to 5 years The maximum grade for each type of toxicity will be recorded for each patient at each treatment evaluation. The frequency of each type of toxicity will be determined.
