Non-Hodgkin's Lymphoma
Conditions
Brief summary
This two-stage, multi-center, randomized, controlled, open-label study will investigate the pharmacokinetics, efficacy and safety of rituximab SC versus rituximab IV in participants with previously untreated follicular non-Hodgkin's lymphoma. Participants will be randomized to receive 375 milligrams per meter square (mg/m\^2) rituximab as IV infusion or 1400 milligrams (mg) rituximab SC. In addition, participants will receive standard chemotherapy. Participants who achieved a complete or partial response (PR) after 8 treatment cycles, will receive maintenance treatment for a further maximum number of 12 cycles. Maintenance treatment cycles will be repeated every 8 weeks. This is a two-stage study. Stage 1 was designed to confirm the chosen rituximab SC dose resulting in comparable rituximab serum Ctrough levels compared with rituximab IV, when given as part of induction treatment every 3 weeks. Enrollment for Stage 2 started after the rituximab SC dose was established in Stage 1. Stage 2 aimed to further investigate the efficacy and safety of rituximab SC compared with rituximab IV. The anticipated time on study treatment is 96 weeks.
Interventions
First cycle of rituximab IV infusion (375 mg/m\^2) + 7 cycles of rituximab SC (1400 mg; rituximab induction) in administered every 3 weeks. Participants achieving at least PR entered rituximab SC (1400 mg) maintenance therapy once every 8 weeks for 24 months.
Eight cycles of rituximab IV infusion (375 mg/m\^2; rituximab induction) administered every 3 weeks. Participants achieving at least PR during induction, entered rituximab IV maintenance therapy (375 mg/m\^2) once every 8 weeks for 24 months.
Eight cycles of cyclophosphamide (750 mg/m\^2 IV) administered every 3 weeks.
Eight cycles of doxorubicin (50 mg/m\^2 IV) administered every 3 weeks.
Eight cycles of doxorubicin (1.4 mg/m\^2 IV) administered every 3 weeks.
Eight cycles of prednisone/prednisolone (100 mg/day or 40 mg/m\^2/day IV/orally) administered Days 1 to 5 of every 21 days cycle.

Percentage of Responses Who Showed Rituximab SC Formulation Convenient as Compared to Rituximab IV Formulation as Assessed by Physician/Nurse Opinion
All investigator physicians and nurses involved in this study were asked to complete question i.e. Which formulation of rituximab (SC or IV) do you think is more convenient? based on their experience with the rituximab SC and IV formulations across all participants and presented as rituximab SC is much more convenient; rituximab SC is a little more convenient; both formulations are equally convenient; rituximab IV is a little more convenient; and rituximab IV is much more convenient.
Time frame: After Cycle 8 of induction treatment (24 weeks) and during the maintenance part of the study after 12 months (i.e., Cycle 15), and after the end of the maintenance treatment, (i.e., Cycle 20) (1 Cycle=4 weeks for Cycle 8 and 8 weeks for Cycles 15 and 20)

Stage I and II (Pooled): Event-Free Survival Assessed Using International Working Group Response Criteria for NHL
Event-free survival was defined as the time from randomization to disease progression/relapse, death or initiation of new NHL therapy. If the specified event (progression/relapse, death or new anti-lymphoma treatment) did not occur, event-free survival was censored at the last tumor assessment date either during treatment or follow up. Event-free survival analysis was performed using Kaplan-Meier curves. Baseline, D1 of all cycles (Cy 1-20) (1 Cy=3 weeks for Cy1-8 & 8 weeks for Cy9-20), at early withdrawal, at follow-up, every 12 weeks for 96 weeks or until documented disease progression/relapse or death (up to a median of 27 months; up to data cutoff of 31 Oct 2017 \[up to 6 years\])
