Arm A: DRL_RI
Subjects who have already received at least 1 full course comprising two 1000 mg infusions of either US-rituximab or EU-rituximab and are candidates for re-treatment with Rituximab, will be enrolled. DRL\_RI will be administrated in combination with MTX as two 1000 mg infusions on Day 1 and Day 15 Experimental: Arm A: DRL\_RI: Proposed rituximab biosimilar, 100mg or 500mg, concentrate for solution for infusion
Arm B: US-Rituximab or EU-Rituximab
Subjects who have already received at least 1 full course comprising two 1000 mg infusions of either US-rituximab or EU-rituximab and are candidates for re-treatment with rituximab, will be enrolled. Patients enrolled in Arm -B will continue to receive US-rituximab or EU-rituximab. The rituximab reference product used (US-licensed rituximab \[Rituxan\] or EU-approved rituximab \[MabThera\]) should be the same in the prior and the randomized treatment course, respectively. Arm B: Rituxan®/Mabthera®: Reference product US- rituximab (Rituxan®) or EU-rituximab (MabThera®), 100mg or 500mg, concentrate for solution for infusion
