Complete response was evaluated by an Independent Radiology Review Committee using available computed tomography (CT) and positron emission tomography (PET) scans collected at Baseline, end of cycle 3, and end of cycle 6 (or end of treatment) based on the Revised Response Criteria for Malignant Lymphoma.

1. Complete disappearance of all detectable clinical evidence of disease and disease-related symptoms if present before therapy.
2. PET scan was negative.
3. The spleen and/or liver, if enlarged before therapy on the basis of physical examination or CT scan, was not palpable on physical examination and was considered normal size by imaging studies; all splenic and hepatic nodules related to lymphomas disappeared.
4. If bone marrow was involved before treatment, the infiltrate cleared on repeated bone marrow biopsy.
5. No new sites of disease were detected.

All randomized subjects with non-GCB DLBCL who received at least 1 dose of any study drug, had at least 1 measurable lesion at baseline, and had at least 1 post-baseline response assessment

Overall response = Complete Response (CR) + Partial Response (PR) Response was evaluated by an Independent Radiology Review Committee using available computed tomography (CT) and positron emission tomography (PET) scans collected at Baseline, end of cycle 3, and end of cycle 6 (or end of treatment) based on the Revised Response Criteria for Malignant Lymphoma.

Complete Response: see primary endpoint Partial Response: At least a 50% decrease in the sum of the product of the diameters (SPD) of up to 6 of the largest dominant nodes or nodal masses.

Proportion of subjects who achieved a CR or PR with duration of at least 6 months. Duration of response (CR or PR) was calculated from the date of initial documentation of a response to the date of first documented evidence of disease progression or death due to disease progression. Response was evaluated by an Independent Radiology Review Committee using available computed tomography (CT) and positron emission tomography (PET) scans collected at Baseline, end of cycle 3, end of cycle 6 (or end of treatment) based on the Revised Response Criteria for Malignant Lymphoma.

Kaplan-meier estimate of subsequent anti-lymphoma therapy at 1-year. Time to subsequent anti-lymphoma therapy was measured from the date of randomization to the start date of new treatment. Death due to disease progression prior to subsequent therapy was considered as an event. Otherwise, time to next anti-lymphoma treatment was censored at the date of death or the last date known to be alive.

Intent to Treat Population

Kaplan-meier estimate of progression-free survival at 1-year. Progression-free survival was defined as the interval between the date of randomization and the date of first documented evidence of disease progression or death.

Kaplan-meier estimate of overall survival at 1-year measured from date of randomization.
