  1. Abbreviations: EU-rituximab, European Union approved rituximab (MabThera®); TEAE, treatment-emergent adverse event; SAE, serious adverse event; USrituximab, United States licensed rituximab (Rituxan®)
  2. a Patient had reported Grade 2 drug hypersensitivity (to amlodipine), leading to treatment discontinuation
  3. Note: The number of patients is represented by n. Each patient was counted only once if the patient reported 1 or more events, the number of events is represented as (e) and could include multiple events for a patient. Percentages are based on the number of patients in the safety population
