What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and tolerability of Urelumab in combination with Rituximab as measured by incidence of adverse events (AEs), serious AEs, death, vital sign changes, electrocardiograms (ECGs), physical examination results, and laboratory test abnormalities |  | Up to 60 days after last dose of Urelumab | 
| Safety and tolerability of Urelumab in combination with Rituximab as measured by incidence of adverse events (AEs), serious AEs, death, vital sign changes, electrocardiograms (ECGs), physical examination results, and laboratory test abnormalities |  | Up to 110 days after last dose of Rituximab | 

Secondary Outcome Measures
