Study Summary

This trial studies how well bendamustine and rituximab in combination with copanlisib work in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma. Drugs used in chemotherapy, such as bendamustine and rituximab, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Copanlisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bendamustine and rituximab with copanlisib may work better than bendamustine and rituximab alone in treating chronic lymphocytic leukemia or small lymphocytic lymphoma.

Primary Outcome

Will use a Simon optimal two-stage design.
