Study of Acalabrutinib (ACP-196) in Combination With Venetoclax (ABT-199), With and Without Obinutuzumab (GA101) Versus Chemoimmunotherapy for Previously Untreated CLL

Official Title

A Randomized, Multicentre, Open-Label, Phase 3 Study to Compare the Efficacy and Safety of Acalabrutinib (ACP-196) in Combination With Venetoclax With and Without Obinutuzumab Compared to Investigator's Choice of Chemoimmunotherapy in Subjects With Previously Untreated Chronic Lymphocytic Leukemia Without Del(17p) or TP53 Mutation

Summary:

The purpose of this study is to evaluate the efficacy and safety of acalabrutinib in combination with venetoclax and acalabrutinib in combination with venetoclax with and without obinutuzumab compared to chemoimmunotherapy in subjects with previously untreated CLL.

Trial Description

Primary Outcome:

• To evaluate the efficacy of acalabrutinib with venetoclax (Arm A) compared to chemoimmunotherapy fludarabine/cyclophosphamide/rituximab [FCR] or bendamustine/rituximab [BR] (Arm C): PFS

Secondary Outcome:

• To evaluate the efficacy of acalabrutinib with venetoclax in combination with obinutuzumab (Arm B) compared with FCR or BR (Arm C): PFS
• To evaluate the efficacy of acalabrutinib with venetoclax (Arm A) compared with FCR or BR (Arm C): PFS defined the same as above per investigator assessment.

This randomized, global, multicentre, open-label, Phase 3 study will evaluate the efficacy and safety of AV and AVG versus chemoimmunotherapy (FCR or BR) in subjects with previously untreated CLL without del(17p) or TP53. Subjects will be randomized in a 1:1:1 ratio into 3 arms through a block stratified randomization procedure. The study includes screening (35 days), treatment (from randomization until study drug discontinuation) and follow-up phase.
