Overview
Brief Summary
This is a prospective international, multi-center, randomized, double-blind controlled study designed to assess and compare the pharmacokinetics, pharmacodynamics and the safety of PBO-326 (Rituximab) and Mabthera (Rituximab) in combination with CHOP in previously untreated patients with diffuse B cells Non Hodgkin lymphoma.
Detailed Description
At present R-CHOP (Rituximab plus Cyclofosfamide, Doxorrubicine, Vincristine and Prednisone) has became standard of care of patients with B cells Non Hodgkin Lymphoma CD20+. Study will perform pharmacodynamic (PD) and pharmacokinetic (PK) measurment of a novel Rituximab in comparison with Mabthera and evaluates safety both metabolic as well immunologic. Study protocolo is designed to provide data on impact of treatment interchange of both study drugs (PBO-326 and Mabthera).

Outcomes
Primary Outcomes
Basal and final serum CD 20 levels comparison.
Time Frame: Every 14 days for the duration of treatment
Primary outcome is the depletion of CD20+ B cells. This will be measured every 14 days and comparison will be made basal levels versus visit 2, visit 3, visit 4, visit 5, visit 6, visit 7 and visit 8.
Secondary Outcomes
- Comparison of safety of PBO-326 versus Mabthera(Every 14 days measurements)
