Participants with r/r FL and DLBCL received RTX at a dose of 375 mg/m\^2 administered via IV infusion on Day 1 and pinatuzumab vedotin at a dose of 2.4 mg/kg administered via IV infusion on Day 2 for the first 2 cycles. RTX and pinatuzumab were administered on the same day (Day 1) in subsequent cycles beginning with the third cycle, in the absence of any infusion-related adverse events. Participants who developed PD were treated with RTX at 375 mg/m\^2 and polatuzumab vedotin at 2.4 mg/kg via IV infusion on Day 1, beginning no later than 42 days after the last dose of the prior study treatment until a second PD event, clinical deterioration, and/or intolerance to the crossover treatment for up to a maximum of 1 year (maximum 17 cycles on an every-21-day schedule).

Analysis was performed on safety-evaluable population (only participants who received pinatuzumab vedotin). Here, 'Overall Number of Participants Analyzed' signifies the number of participants evaluable for this outcome measure and 'Number Analyzed' signifies the number of participants evaluable at specified time points.
