This study is evaluating the efficacy of acalabrutinib in combination with bendamustine and rituximab (BR) compared with placebo plus BR in subjects with previously untreated mantle cell lymphoma.

To evaluate the efficacy of acalabrutinib in combination with bendamustine and rituximab (BR) compared with placebo plus BR based on Independent Review Committee (IRC) assessment of progression-free survival (PFS) per the Lugano Classification for Non-Hodgkin Lymphoma (NHL) in subjects with previously untreated mantle cell lymphoma (MCL).
