Measure: GEOMETRIC_MEAN
Unit: ng/mL
Interval / dispersion: Geometric Coefficient of Variation
Time frame: Cycle 1 Day 2: pre-dose, 5 min, 1 hour (h); 2h, 3h and 4h post dose

What was measured

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

Analysis population: PK evaluable population included all the ITT participants Phase Ib and 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.
