  • Fulvestrant With or Without Lapatinib in Treating Postmenopausal Women With Stage III or Stage IV Breast Cancer That is Hormone Receptor-Positive

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies fulvestrant and lapatinib to see how well they work compared to fulvestrant and a placebo in treating postmenopausal women with stage III or stage IV breast cancer that is hormone receptor-positive. Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Lapatinib may stop the growth of breast cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether fulvestrant is more effective with or without lapatinib in treating breast cancer.

  • Paclitaxel, Nab-paclitaxel, or Ixabepilone With or Without Bevacizumab in Treating Patients With Stage IIIC or Stage IV Breast Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies the side effects and how well different chemotherapy regimens with or without bevacizumab work in treating patients with stage IIIC or stage IV breast cancer. Drugs used in chemotherapy, such as paclitaxel, paclitaxel albumin-stabilized nanoparticle formulation (nab-paclitaxel), and ixabepilone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab may block tumor growth by targeting certain cells and slowing the growth of blood vessels to the tumor. It is not yet known which treatment regimen is more effective in treating patients with breast cancer.

  • Tamoxifen Citrate or Letrozole With or Without Bevacizumab in Treating Women With Stage III or Stage IV Breast Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies tamoxifen citrate or letrozole together with bevacizumab to see how well it works compared with tamoxifen citrate or letrozole alone in treating women with stage III or stage IV breast cancer. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate* or letrozole may fight breast cancer by blocking the use of estrogen by the tumor cells. Monoclonal antibodies, such as bevacizumab, may help control breast cancer by stopping the growth of blood vessels to the tumor. It is not yet known whether giving hormone therapy is more effective with or without bevacizumab in treating advanced breast cancer.
