Pharmacokinetics and Pharmacodynamics of BI 695500 vs. Rituximab as First Line-treatment in Patients With Low Tumor Burden Follicular Lymphoma

A Randomized, Double-blind, Parallel-arm, Phase I Study to Evaluate the Pharmacokinetics and Pharmacodynamics of BI 695500 vs. Rituximab (MabThera) Induction Immunotherapy as a First-line Treatment in Patients With Low Tumor Burden Follicular Lymphoma

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).

• Treatment within a clinical trial within 4 weeks prior to initiation of trial treatment. Patients who have received treatment with a drug that has not received regulatory approval for any indication within 4 weeks or a minimum of 5 half-lives, whichever is longer, of the initial dose of trial medication.
• Any other co-existing medical or psychological condition(s) that will preclude participation in the trial or compromise ability to give informed consent and/or comply with study procedures.
