What was measured

Cycle length is 21 days for DLBCL cohorts and 28 days for FL cohorts. As pre specified in the protocol serum concentration of rituximab was not assessed in the Phase II NF Cohort (Arm G+H).

Analysis population: PK evaluable population included all the ITT participants in Cohort 1a (Phase Ib) and Arms A-D (Phase II) who received at least one study treatment and who provided suitable PK samples. 'Overall Number Analyzed' are the number of participants with data available for analysis. 'Number Analyzed' is the number of participants with data available for analysis at a specified timepoint.

Groups in this outcome

Cohort 1a (Phase Ib Safety Run-In): Pola+BR in FL

Participants with FL received pola, 1.8 mg/kg, as IV infusion on Day 2 of Cycle 1 (each cycle is 28 days), and thereafter on Day 1 of Cycles 2 to 6. Participants also received bendamustine 90 mg/m\^2, as IV infusion on Days 2 and 3 of Cycle 1, and thereafter on Days 1 and 2 of Cycles 2 to 6 and rituximab, 375 mg/m\^2, as IV infusion on Day 1 of Cycles 1 to 6, in combination with pola.
