Study Details

FIL\_FOLL19 is an open-label, multicenter, randomized phase III trial. The sponsor of this clinical trial is Fondazione Italiana Linfomi (FIL). The Primary Objective of the study is to demonstrate that, in patients with newly diagnosed, advanced stage Follicular Lymphoma (FL) with high tumor burden according to the Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria, a treatment strategy that reduces the number of chemotherapy cycles in case of early response to immunochemotherapy is not inferior compared to standard therapy at full dose in terms of Progression-Free Survival (PFS).

Arms

  • Experimental: Standard arm (A)
    Patients will start immunochemotherapy with one of the approved regimens (R-CHOP, R-Bendamustine, G-CHOP, G-Bendamustine, G-CVP). Patients randomized to Arm A will receive an induction immunochemotherapy at full doses (standard schedule). After cycle 4, patients will be assessed for response and will complete their planned therapy if at least a stable disease is confirmed. At the end of induction responding patients (CR, PR) will be addressed to a standard anti-CD20 maintenance (1 dose every 8 weeks for two years) with the same Monoclonal Antibody (MoAb) given during induction.
  • Experimental: Experimental arm (B)
    Patients will start immunochemotherapy with one of the approved regimens (R-CHOP, R-Bendamustine, G-CHOP, G-Bendamustine, G-CVP). Patients randomized to Arm B will start their induction treatment with 4 cycles of the immunochemotherapy standard dose chosen by the physician: after cycle 4, patients will be assessed for response and will proceed with subsequent treatment based on the quality of their response. Specifically: * Patients achieving a CR will receive a shortened treatment: in detail, they won't receive any further chemotherapy but will complete induction with 4 additional cycles of only the Monoclonal Antibody (MoAb) given during the first four cycles; * In case if response less than CR, (PR,SD), patients will complete treatment as planned for patients in Arm A. At the end of induction responding patients (CR, PR) will be addressed to a standard anti-CD20 maintenance (1 dose every 8 weeks for two years) with the same Monoclonal Antibody (MoAb) given during induction.
