Nab-Paclitaxel and Bevacizumab or Ipilimumab as First-Line Therapy in Treating Patients With Stage IV Melanoma That Cannot Be Removed by Surgery

This randomized phase II trial studies how well nab-paclitaxel and bevacizumab or ipilimumab works as first-line therapy in treating patients with stage IV melanoma that cannot be removed by surgery. Drugs used in chemotherapy, such as nab-paclitaxel, 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 stop the growth of tumor cells by binding to a protein called vascular endothelial growth factor (VEGF) and by preventing the growth of new blood vessels that tumors need to grow. Ipilimumab blocks a substance called cytotoxic T-lymphocyte-associated antigen-4 (CTLA4) on the surface of T cells and may help the immune system kill cancer cells. It is not yet known whether nab-paclitaxel and bevacizumab is more effective than ipilimumab in treating melanoma.
