Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Lenalidomide | For participants with normal renal function \[defined as Creatinine Clearance (CrCL ) ≥ 60 mL/min\], 5 mg lenalidomide was administered by mouth (PO) once daily (QD) on Days 1 through 28 of the first 28-day cycle, 10 mg lenalidomide PO QD on Days 1 through 28 starting at cycle 2, 15 mg lenalidomide PO QD starting at cycle 3 and for the remainder of the study until progressive disease (PD) or unacceptable toxicity, whichever occurred first. For participants with moderate renal impairment (defined as CrCL ≥ 30 to \< 60 mL/min), 2.5 mg lenalidomide PO QD on Days 1 through 28 of the first 28-day cycle, 5 mg lenalidomide PO QD on Days 1 through 28 starting at cycle 2, 7.5 mg lenalidomide PO QD starting at cycle 3 and for the remainder of the study until PD or unacceptable toxicity, whichever occurred first. | 100 | 224 | EG000 |
| Group 2 | Chlorambucil | Chlorambucil oral tablets at 0.8 mg/kg on Days 1 and 15 of each 28-day cycle for a total duration of 12 months | 93 | 223 | EG001 |
