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/Bendamustine n=36 Participants 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.
