Patients be randomized in a 1:1 ratio into 2 arms to receive either acalabrutinib monotherapy (Arm A) or rituximab in combination with chlorambucil (Arm B). The primary objective of this study is to compare the efficacy of acalabrutinib relative to chlorambucil plus rituximab in subjects with previously untreated chronic lymphocytic leukemia without del(17p) or TP53 mutation.
This is a randomized, multicenter, open-label, Phase 3 study to evaluate the efficacy and safety of Acalabrutinib versus Chlorambucil plus Rituximab in subjects with Previously Untreated Chronic Lymphocytic Leukemia.
