Study Description

Brief Summary: CLL2-BZAG is a prospective, open-label, multicenter phase-II trial to evaluate the efficacy and safety of a sequential regimen of bendamustine followed by obinutuzumab (GA101), zanubrutinib (BGB-3111) and venetoclax (ABT-199) in patients with relapsed/refractory CLL.

Detailed Description: In the CLL2-BZAG trial will be included a total of 40 patients with relapsed or refractory CLL in need of treatment. This trial will evaluate a debulking with two cycles bendamustine (only for patients with a high tumor load), followed by an induction and maintenance treatment with obinutuzumab, zanubrutinib and venetoclax in patients with relapsed/refractory CLL. Thus, this trial combines one established (chemotherapy) and three novel, synergistic (antibody, Bruton's tyrosine kinase(BTK)-inhibitor and Bcl-2 antagonist) principles of action in order to achieve deep and long lasting remissions with a short duration of treatment. Additionally, this trial has an extensive accompanying scientific program aiming at a better understanding of the kinetics of response and clonal evolution of CLL.
