Bevacizumab and Cediranib Maleate in Treating Patients With Metastatic or Unresectable Solid Tumor, Lymphoma, Intracranial Glioblastoma, Gliosarcoma or Anaplastic Astrocytoma

This phase I trial is studying the side effects and best dose of bevacizumab and cediranib maleate in treating patients with metastatic or unresectable solid tumor, lymphoma, intracranial glioblastoma, gliosarcoma or anaplastic astrocytoma. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Cediranib maleate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Bevacizumab and cediranib maleate may also stop the growth of cancer cells by blocking blood flow to the cancer. Giving bevacizumab together with cediranib maleate may kill more cancer cells.
