Study Summary

This study will test the safety of limiting treatment time with acalabrutinib and obinutuzumab in people who have chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The researchers want to find out whether stopping the study drugs when the cancer responds to the treatment, followed by a period of observation in which no treatment is given, is better than, the same as, or worse than the usual approach. A usual treatment for CLL and SLL is to give the study drugs continuously until the cancer progresses, even if the disease is in remission. But when people receive these drugs for long periods of time, they can have serious side effects and their cancer can become resistant to treatment.

Primary Outcome

Progression free survival (PFS) will be measured from the time the patient initiates treatment, until documented progression of disease, relapse, or death due to any cause, whichever comes first.
