Study Groups

Obinutuzumab
Obinutuzumab (100 mg on Day 1 of Cycle 1, 900 mg on Day 2 of Cycle 1, and 1000 mg on Days 8 and 15 of Cycle 1 and Day 1 of Cycle 2; for Cycles 3 - 6 (1000 mg on Day 1) only as needed for participants to achieve low tumor burden) was administered via intravenous infusion during the debulking regimen.
After debulking, obinutuzumab (1000 mg) was administered via intravenous infusion on Day 1 of one 5-week and four 4-week cycles during the obinutuzumab/venetoclax combination part of the regimen. Venetoclax was administered according to a weekly ramp-up schedule over 5 weeks to the recommended daily dose of 400 mg.
Obinutuzumab
Administered via intravenous infusion
Venetoclax
The venetoclax dose was administered according to a weekly ramp-up schedule over 5 weeks to the recommended daily dose of 400 mg. Venetoclax was continued for a total duration of up to 53 weeks, including the 5-week ramp-up schedule. Participants were instructed to take venetoclax tablets with a meal and water at approximately the same time each day. Venetoclax tablets were to be swallowed whole and not chewed, crushed, or broken prior to swallowing.
Obinutuzumab/bendamustine
Obinutuzumab (100 mg on Day 1 of Cycle 1, 900 mg on Day 2 of Cycle 1, and 1000 mg on Days 8 and 15 of Cycle 1 and Day 1 of Cycle 2; for Cycles 3 - 6 (1000 mg on Day 1) only as needed for participants to achieve low tumor burden) was administered via intravenous infusion during the debulking regimen. Bendamustine (90 mg/m\^2 ) was to be administered to those with nodes or nodal mass \> 10 cm, or with del(11q) and \> 5 cm nodes, or at the discretion of the investigator as above, via intravenous infusion over 10 minutes on Days 1 and 2 (or Days 2 and 3 at the discretion of the investigator during Cycle 1) of each 28-day cycle for up to 6 cycles during the debulking regimen.
After debulking, obinutuzumab (1000 mg) was administered via intravenous infusion on Day 1 of one 5-week and four 4-week cycles during the obinutuzumab/venetoclax combination part of the regimen. Venetoclax was administered according to a weekly ramp-up schedule over 5 weeks to the recommended daily dose of 400 mg.
