Study of Acalabrutinib (ACP-196) Versus Ibrutinib in Previously Treated Subjects With High Risk CLL

This research study is evaluating an investigational drug, called ACP-196, in comparison with a drug called ibrutinib as a possible treatment for patients with CLL. The purpose of this study, which involves research, is to determine if an experimental drug: ACP-196 is safe and effective in the treatment of this disease.

Stanford is currently not accepting patients for this trial.
