Significance of Duration of Maintenance Therapy With Rituximab in Non-Hodgkin Lymphomas

Phase 3

Active, not recruiting

• Conditions: Follicular Lymphomas; Non-Hodgkin's Lymphoma; Immunocytomas; Marginal Zone Lymphomas; Lymphocytic Lymphoma; Mantle-Cell Lymphomas
• Interventions: Drug: Rituximab / observation; Drug: Rituximab

• Registration Number: NCT00877214
• Lead Sponsor: Jurgen Barth

Brief Summary

The purpose of this study is to determine if an extended maintenance therapy with Rituximab in follicular and a maintenance therapy in other indolent and mantle cell lymphomas has advantages compared to a shorter or no maintenance therapy.

Detailed Description

Results from several randomised studies show a clinical benefit of a maintenance therapy with rituximab in follicular lymphomas. The advantage of a maintenance therapy in other indolent and mantle cell lymphomas is - due to the lower incidence of these diseases- not well investigated.

This study tries to determine the significance of an extended maintenance therapy with rituximab in follicular lymphomas and the significance of a maintenance therapy other indolent and mantle cell lymphomas compared to observation.
