Overview
Brief Summary
The primary objective of the study is to assess the pharmacokinetic (PK) similarity of Boehringer Ingelheim (BI) 695500 vs. rituximab (MabThera®) in previously untreated patients with low tumor burden follicular lymphoma (LTBFL).
The secondary objective of the study is to evaluate the pharmacodynamics (PD), safety, and anti-tumor activity of BI 695500 vs. rituximab (MabThera®), as well as the presence of anti-drug antibodies (ADAs).

Outcomes
Primary Outcomes
Area Under the Concentration (AUC) Time Curve of BI 695500 and Rituximab (MabThera®) Over the First Dosing Interval (Pre-infusion on Day 1 to Pre-infusion on Day 8)
Time Frame: 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.
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.
Secondary Outcomes
- AUC of BI 695500 and Rituximab (MabThera®) Over the Fourth Dosing Interval (Pre-infusion on Day 22 to Day 29) (AUC Day 22-Day 29)(Blood samplings were done at pre-infusion and at end of infusion at 1, 2, and 4 hours from end of infusion 4, and at 24, 48, 72, 96 and 168 hours from start of infusion 4.)
- Maximum Measured Concentration of BI 695500 and Rituximab (MabThera®) in Plasma (Cmax) Following Dose 1(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.)
- Maximum Measured Concentration of Rituximab (MabThera®) and BI 695500 in Plasma (Cmax) Following Dose 4(Blood samplings were done at pre-infusion and at end of infusion at 1, 2, and 4 hours from end of infusion 4, and at 24, 48, 72, 96, 168, 336, 672, 1344, 2016 and 2880 hours from start of infusion 4.)
- Area Under the Depletion-time Curve of the Cluster of Differentiation (CD)19+ B-cell Count (% Change From Baseline (CFB)) in Peripheral Blood From Pre-infusion on Day 1 Until Last Measurement on Day 8 (Pre-infusion)(Blood samplings were done at pre-infusion and at end of infusion at 1, 2, and 4 hours from end of infusion, and at 24, 48, 72, 96 and 168 hours from start of infusion.)
- Change From Baseline (%) of CD19+ B-cells in Peripheral Blood Measured After Seven Days on Day 8 (Day 8 Pre-infusion Time Point)(Blood sampling was done at 168 hours from start of infusion.)
- Overall Response Rate (ORR) (Complete Response (CR) Plus Partial Response (PR)) Evaluated Approximately One Month After Last Dose of BI 695500 or Rituximab (MabThera®)(at Day 50.)
- Percentage of Patients With Treatment Emergent Adverse Events (TEAEs) Selected for Comparability Assessment of BI 695500 and Rituximab (MabThera®)(Adverse Events (AEs) that started or worsened on or after the first dose of study medication and prior to the last date of study medication + 4 months (120 days) inclusive.)
