Arm Intervention/treatment
Experimental: Obinutuzumab

Participants will be randomized into 2 groups. Group 1 will receive obinutuzumab 1000 mg IV at baseline and Weeks 2, 24, 26, 50, and 52 plus MMF and oral prednisone. Group 2 receive obinutuzumab 1000 mg IV at baseline and Weeks 2, 24, 26, and 52 plus MMF and oral prednisone. Group 2 participants will receive a placebo infusion at their Week 50 visit.

Participants with an adequate response at Week 76 will continue receiving blinded obinutuzumab infusions every 6 months starting at Week 80.

Participants without an adequate response at Week 76 may be eligible for open-label obinutuzumab starting at Week 80.

 Drug: Obinutuzumab
Obinutuzumab will be administered by IV infusion at a dose of 1000 mg at Baseline and Weeks 2, 24, 26, 50 (group 2: placebo), and 52 and subsequently from Week 80 and every 6 months thereafter, based on response.
Other Name: Gazyva, GA101, RO5072759

Drug: MMF
MMF willl be administered at a target dose of 2.0 - 2.5 g/day in divided doses through Week 80.

Drug: Prednisone
Prednisone 0.5 mg/kg/day (maximum 60 mg/day) will be started on Day 2. Beginning on Day 15, prednisone will be tapered to 5 mg/day and continued until Week 80.

Drug: Methylprednisolone
Methylprednisolone 80 mg IV will be administered as predmedication prior to infusions.

Drug: Acetaminophen
Acetaminophen 650-1000 mg will be administered as premedication prior to infusions.

Drug: Diphenhydramine
Diphenhydramine 50 mg will be administered as premedication prior to infusions.
Placebo Comparator: Placebo

Placebo participants will receive obinutuzumab matched placebo at baseline and Weeks 2, 24, 26, 50, and 52 plus MMF and oral prednisone.

Participants with an adequate response at Week 76 will continue receiving blinded obinutuzumab infusions every 6 months starting at Week 80.

Participants without an adequate response at Week 76 may be eligible for open-label obinutuzumab starting at Week 80.

 Drug: Obinutuzumab
Obinutuzumab will be administered by IV infusion at a dose of 1000 mg at Baseline and Weeks 2, 24, 26, 50 (group 2: placebo), and 52 and subsequently from Week 80 and every 6 months thereafter, based on response.
