What was measured

Event free survival was measured from the day of randomization to the date of first documented PD, relapse after response, start of a new treatment or death from any cause. Patients without an EFS event were censored at their last tumor assessment date.

Analysis population: Intent-to-treat (ITT) population was comprised of all patients randomized in the study, irrespective of whether they received treatment or not.

Groups in this outcome

Fludarabine+Cyclophosphamide (FC)

Fludarabine+cyclophosphamide (FC) intravenously for a total of 6 treatment cycles at intervals of 28 days. Fludarabine: 25 mg/m² IV on Days 1, 2, 3 for 6 cycles. Cyclophosphamide: 250 mg/m² IV on Days 1, 2, 3 for 6 cycles.

Fludarabine+Cyclophosphamide+Rituximab (FCR)

Rituximab and FC intravenously for a total of 6 treatment cycles at intervals of 28 days. Cycle 1: rituximab 375 mg/m² IV on Day 1; fludarabine 25 mg/m² IV on Days 2, 3, 4; cyclophosphamide 250 mg/m² IV on Days 2, 3, 4.
