Eligible patients will be randomly assigned to either the investigational treatment arm (RB alternating with RBAC) or the standard treatment arm (RB) in a 1:1 ratio. Patients will be stratified by age (≥70 years vs. 60-69), histologic morphology (blastoid/pleomorphic vs. non-blastoid/non-pleomorphic), and MIPI-C risk score (0/1 vs. 2/3).
This is a phase 2, multicenter, open-label, active-controlled randomized trial to determine efficacy and safety of rituximab/bendamustine (RB) alternating with rituximab/bendamustine/cytarabine (RBAC) compared with standard RB alone in the first-line treatment of elderly patients with mantle cell lymphoma, who are not eligible for high-dose therapy followed by autologous stem cell transplantation.
