Atezolizumab, Obinutuzumab, and Venetoclax in Treating Patients With Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or Relapsed or Refractory Richter Syndrome

Description

This phase II trial studies how well atezolizumab, obinutuzumab, and venetoclax work in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma or Richter syndrome that has come back (recurrent) or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as atezolizumab and obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as venetoclax, 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. Giving atezolizumab, obinutuzumab, and venetoclax may work better in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or Richter syndrome.

Conditions

Chronic Lymphocytic Leukemia, Recurrent Transformed Chronic Lymphocytic Leukemia, Refractory Transformed Chronic Lymphocytic Leukemia, Richter Syndrome, Small Lymphocytic Lymphoma
