Experimental: GP2013 - proposed biosimilar rituximab
10 mg/mL in 500 mg (50 mL) single-use vials. For i.v. administration, two 500 mg vials (1000 mg of active molecule) of concentrate are diluted in 0.9% NaCl solution and infused i.v. The treatment course consists of 2 i.v. infusions 2 weeks apart (at Day 1 and Day 14).

- Number of Patients Experiencing Anaphylactic Reactions [ Time Frame: Within 24 hours of each study drug infusion: on Day 1 and Day 14 ]
2006 NIAID/FAAN* criteria were used for identification of anaphylactic reactions within 24h of each study drug infusion.
For patients with no history of infusion-related reactions during their previous treatments with rituximab, symptoms/signs in at least 2 out of 4 organ systems:
- Skin/mucosal tissue
- Respiratory organs
- Drop of systolic blood pressure (<90 mmHg or variance from baseline >30%) or associated symptoms
- Gastrointestinal organs were defined as an anaphylactic reaction.
The same criteria were also applied to patients with history of infusion-related reactions during their previous treatments with rituximab. In addition, if these patients experienced only a rapid drop in systolic blood pressure (<90 mmHg or variance from baseline >30%), this was defined as an anaphylactic reaction disregarding involvement of other organ systems.

- Number of Patients Experiencing Hypersensitivity Reactions [ Time Frame: 24 weeks study duration ]The standardized MedDRA query (SMQ) - Hypersensitivity reactions (SMQ 20000214) was used for the identification of hypersensitivity reactions overall from first infusion in the adverse event database.
- Immunogenicity [ Time Frame: 24 weeks study duration ]
Number of patients tested positive for anti-drug-antibodies (ADA) post-randomization.
Patients with negative ADA results at screening and at least one evaluable post-randomization ADA assessment are included in the analysis
- Number of Patients Experiencing Potential Infusion-Related Reactions [ Time Frame: On the day of and on the day after each study drug infusion (e.g. on study day 1 and 2 for the 1st study drug infusion and on study day 14 and 15 for the 2nd study drug infusion, if the second drug infusion was given on study day 14) ]Patients, experienced infusion related reactions repeatedly (i.e. during the first and second infusion) are counted only once in the overall line.
