Clinical Trial Summary

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).

Clinical Trial Description

This is an open-label, multicenter, randomized phase III trial. The study plans to randomize patients with a 1:1 ratio to Arm A (Standard arm) or Arm B (Experimental arm). Once randomized, each patient will start immunochemotherapy with one of the approved regimens (R-CHOP, R-Bendamustine, G-CHOP, G-Bendamustine, G-CVP) chosen by the physician on a patient basis before randomization. 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. 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 Complete Remission (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 of G-bendamustine, 2 additional cycles of obinutuzumab); - In case if response less than Complete Remission (CR), Partial Remission (PR) or Stable Disease (SD), patients will complete treatment as planned for patients in Arm A. In both arms, 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. Patients with progressive disease at any time (regardless of treatment arm) will be addressed to salvage therapy. The study plans the evaluation of quality of life by collecting the Patient-Reported Outcome(s) (PROs) through the Functional Assessment of Cancer Treatment-Lymphoma (FACT-Lym questionnaire) at predetermined timepoints during the study. ;
