What was measured

Time to progression-free survival (PFS) event was defined as the time between randomization and the date of first documented PFS event: disease progression, relapse or death by any cause, whichever came first.

Analysis population: Participants from the Intent-to-treat population, all randomized participants, who experienced a PFS event. Participants who did not have a PFS event at the time of the final analysis were censored at the date of the last contact.

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. Cycles 2-6: rituximab 500 mg/m² IV on Day 1; fludarabine 25 mg/m² IV on Days 1, 2, 3; cyclophosphamide 250 mg/m² IV on Days 1, 2, 3.
