Rituximab Maintenance Versus Observation After R2 Induction in Previously Untreated Marginal Zone Lymphoma (ROMA)

12. juni 2026 opdateret af: Qingqing Cai, Sun Yat-sen University

Rituximab Maintenance Versus Observation After Rituximab and Lenalidomide (R2) Induction in Previously Untreated Marginal Zone Lymphoma: A Multicenter, Phase 2, Randomized Trial

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Rituximab
Patients will receive induction therapy with rituximab and lenalidomide. If CR or PR: maintenance therapy with rituximab every 8 weeks for 2 years.
Medicin: 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.
Aktiv komparator: Observation
Patients will receive induction therapy with rituximab and lenalidomide. If CR or PR: observation.
Andet: 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.
