What was measured
Progression-free survival in the overall study population was defined as the time from randomization until the first documented day of disease progression or death from any cause, whichever occurred first, on the basis of investigator assessments according to the Revised Response Criteria for Malignant Lymphoma. Progression was defined as at least 50% increase in nodal lesions or \>/=50% increase in any node \> 1 centimeter (cm) or \>/= 50% increase in other target measurable lesions (e.g., splenic or hepatic nodules) and/or appearance of any new bone marrow involvement and/or appearance of any new lesion \> 1.5 cm or \>/= 50% increase in any previously involved node with a diameter \</= 1 cm such that it is now \>1.5 cm. Tumor measurements were obtained by CT/MRI.
Analysis population: The ITT population defined as all randomized participants grouped according to their randomized treatment arm regardless of what treatments were actually received.
Groups in this outcome
Rituximab+Chemotherapy
Participants will receive either 8 cycles of rituximab along with 6 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) (21-day cycle) or 8 cycles of rituximab along with 8 cycles of cyclophosphamide, vincristine, and prednisone (CVP) (21-day cycles) or 6 cycles of rituximab along with 6 cycles of bendamustine (28-day cycle) during the induction period. The induction period will be followed by either a maintenance or observation period for responders or non-responders, respectively. Responders will receive rituximab monotherapy every 2 months for 2 years during the maintenance period. Non-responders will receive no protocol specified treatment during the 2-year observation period. Finally, participants will be followed during a 5-year follow-up period. The chemotherapy regimen (CHOP or CVP or bendamustine) for individual participant will be chosen by the site prior to initiation of the study.
Obinutuzumab+Chemotherapy
Participants will receive either 8 cycles of obinutuzumab along with 6 cycles of CHOP (21-day cycle) or 8 cycles of obinutuzumab along with 8 cycles of CVP (21-day cycles) or 6 cycles of obinutuzumab along with 6 cycles of bendamustine (28-day cycle) during induction period. The induction period will be followed by either a maintenance or observation period for responders or non-responders, respectively. Responders will receive obinutuzumab monotherapy every 2 months for 2 years during the maintenance period. Non-responders will receive no protocol specified treatment during the 2-year observation period. Finally, participants will be followed during a 5-year follow-up period. The chemotherapy regimen (CHOP or CVP or bendamustine) for individual participant will be chosen by the site prior to initiation of the study.
