PRIMARY outcome

Timeframe: Blood samplings were done at pre-infusion and at end of infusion at 1, 2, and 4 hours from end of infusion 1, and at 24, 48, 72, 96 and 168 hours from start of infusion 1.

Population: The PK analysis Set Inferential (PKSI) used for inferential analysis of PK parameters, consisted of all randomized subjects who received at least one dose of trial medication and had an estimable primary PK parameter value and were without important protocol deviations that would significantly affect the PK of BI 695500 or Rituximab (MabThera®).

This outcome measure presents area under the concentration time curve of BI 695500 and Rituximab (MabThera®) over the first dosing interval (pre-infusion on Day 1 to pre-infusion on Day 8) (AUCDay 1-Day 8) for assessment of PK (Pharmacokinetics) similarity.
