Official title
Rituximab Maintenance Versus Observation After Rituximab and Lenalidomide (R2) Induction in Previously Untreated Marginal Zone Lymphoma: A Multicenter, Phase 2, Randomized Trial
Overview
This is a multicenter, phase 2, randomized trial to compare rituximab maintenance with observation after rituximab and lenalidomide (R2) induction therapy in patients with previously untreated marginal zone lymphoma. Patients who achieve complete response or partial response after R2 induction will be randomized to receive rituximab maintenance or observation.
Interventions
- Drug Rituximab
Patients will receive R2 induction therapy consisting of rituximab and lenalidomide. Patients who achieve complete response or partial response after induction will receive rituximab maintenance every 8 weeks for up to 2 years. - Other Observation
Patients will receive R2 induction therapy consisting of rituximab and lenalidomide. Patients who achieve complete response or partial response after induction will undergo observation without maintenance anti-lymphoma therapy.
Primary outcome measures
- 2-year progression-free survival rate [Time frame: At 2 years after randomization]
Secondary outcome measures (9)
- Complete response rate [Time frame: Up to 24 months after randomization]
- Overall response rate [Time frame: Up to 24 months after randomization]
- Duration of response [Time frame: Up to 24 months after randomization]
- Overall survival [Time frame: Up to 24 months after randomization]
- Event-free survival [Time frame: Up to 24 months after randomization]
- Disease-free survival [Time frame: Up to 24 months after randomization]
- Incidence of progression of disease within 24 months [Time frame: Within 24 months from the start of induction therapy]
- Patient-reported outcomes [Time frame: Up to 24 months after randomization]
- Incidence of adverse events and serious adverse events [Time frame: Up to 30 days after the last study treatment or during follow-up as clinically indicated]
