Phase III Randomized Multicenter Trial Comparing Continued Maintenance Therapy With the Bevacizumab + Taxane Versus Bevacizumab + Substituting Exemestane in Patients With Metastatic Breast Cancer or Locally Advanced With Estrogen Receptor Positive and Having at Least a Stable Disease After 16 to 18 Weeks of Treatment With Bevacizumab + Taxane.
Phase III Randomized Multicenter Trial Comparing Continued Maintenance Therapy With the Bevacizumab + Taxane Versus Bevacizumab + Substituting Exemestane in Patients With Metastatic Breast Cancer or Locally Advanced With Estrogen Receptor Positive and Having at Least a Stable Disease After 16 to 18 Weeks of Treatment With Bevacizumab + Taxane.
In first-line metastatic breast cancer, the bevacizumab-taxane to progression or toxicity, is currently the standard treatment. In patients expressing hormone receptors, it was shown that hormone therapy administered in maintenance after induction chemotherapy, could have a benefit regarding the progression-free survival. The investigators make the hypothesis that there would be interest to discontinue treatment with taxane after 4 months, and to begin hormone therapy while continuing maintenance bevacizumab.
Exemestane was chosen because it has been shown potentially active in patients who progressed after letrozole, anastrozole or tamoxifen.
