| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to demonstrate that the combination of rituximab and chlorambucil is safe by examining the adverse event profile.; Secondary Objective: The secondary objectives of this study are to determine the following outcome measures: •Overall response rate (ORR), complete response rate (CR), partial response rate (PR) and nodular partial response (nPR) •Progression-free survival •Disease-free survival •Duration of response •Overall survival •Proportion of patients who achieved eradication of detectable minimal residual disease ; Primary end point(s): The primary objective is to demonstrate that the combination of rituximab and chlorambucil is safe. The following safety parameters will be monitored during the study: AEs, SAEs, laboratory tests and physical examination (weight, vital signs and cardiopulmonary examination) | — |
