Eligibility criteria:

        Inclusion Criteria:

          -  Diagnosis of Systemic Lupus Erythematosus (SLE), according to current American College
             of Rheumatology (ACR) criteria

          -  Diagnosis of International Society of Nephrology/Renal Pathology Society (ISN/RPS)
             2003 Class III or IV LN as evidenced by renal biopsy performed within 6 months prior
             to or during screening. Participants may co-exhibit Class V disease in addition to
             either Class III or Class IV disease

          -  Proteinuria (urine protein to creatinine ratio) greater than (>) 1.0

          -  For women who are not postmenopausal (greater than or equal to [>/=] 12 months of
             non-therapy-induced amenorrhea) or surgically sterile (absence of ovaries and/or
             uterus): agreement to remain abstinent or use two adequate methods of contraception,
             including at least one method with a failure rate of less than (<) 1 percent (%) per
             year, during the treatment period and for at least 18 months after the last dose of
             study drug

          -  For men: agreement to remain abstinent or use a condom plus an additional
             contraceptive method that together result in a failure rate of <1% per year during the
             treatment period and for at least 12 months after the last dose of study drug and
             agreement to refrain from donating sperm during this same period

        Exclusion Criteria:

          -  Retinitis, poorly controlled seizure disorder, acute confusional state, myelitis,
             stroke or stroke syndrome, cerebellar ataxia, or dementia that is currently active and
             resulting from SLE

          -  Presence of rapidly progressive glomerulonephritis

          -  Severe renal impairment as defined by estimated Glomerular Filtration Rate (GFR) <30
             milliliters per minute (mL/min) or the need for dialysis or renal transplant

          -  Greater than 50% of glomeruli with sclerosis on renal biopsy

          -  Treatment with cyclophosphamide or calcineurin inhibitors within the 3 months prior to
             randomization

          -  Unstable disease with thrombocytopenia or at high risk for developing clinically
             significant bleeding or organ dysfunction requiring therapies such as plasmapheresis
             or acute blood or platelet transfusions

          -  History of severe allergic or anaphylactic reactions to monoclonal antibodies or known
             hypersensitivity to any component of the obinutuzumab infusion

          -  Significant or uncontrolled medical disease in any organ system not related to SLE or
             LN, which, in the investigator's opinion, would preclude participant participation

          -  Concomitant chronic conditions, excluding SLE, (e.g., asthma, Crohn's disease) that
             required oral or systemic steroid use in the 52 weeks prior to screening

          -  Previous treatment with an anti-cluster of differentiation (CD20)-targeted therapy
             within 12 months

          -  Previous treatment with a biologic B-cell-targeted therapy (other than anti-CD20)
             within 6 months of randomization

          -  Known intolerance to MMF or MPA
