Brief summary
This study is a multicenter phase II trial which primary objective is to assess the anti-lymphoma activity of atezolizumab associated with a BCL-2 inhibitor (GDC-199, venetoclax) and an anti-CD20 monoclonal antibody (obinutuzumab) in three separate cohorts: * relapsed/refractory follicular lymphoma (FL) patients * relapsed/refractory aggressive (DLBCL) lymphoma patients * relapsed/refractory other indolent (iNHL) lymphoma patients (MZL and MALT)

Exclusion criteria
* Lymphocytic lymphoma (LL), waldenström macroglobulinemia, unmeasurable MALT lymphoma, Mantle Cell Lymphoma (MCL) and Follicular lymphoma for cohort 3 * Known CD20 negative status at last biopsy done (Biopsy at relapse/progression is mandatory) * Central nervous system or meningeal involvement by lymphoma * Prior history of Progressive Multifocal Leukoencephalopathy (PML) * Documented infection with HIV * Active Hepatitis B (HB) (positive Hepatitis B surface antigen (Ag-HBs) OR positive serology to hepatitis B (positive Ag-HBs or Hepatitis B core antibody (anti-HBc) or Polymerisation Chain Reaction (PCR) for viral DNA of HBV) Active Hepatitis C (HC) infection (patients with positive HCV serology (anti-HCV) are eligible only if PCR is negative from known HCV RNA) * Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) before inclusion, or any major episode of infection requiring treatment with IV antibiotics or hospitalization (relating to the completion of the course of antibiotics) within 4 weeks prior to first administration of study drug * Active immune-related disease criteria * Left Ventricular Ejection Fraction (LVEF) \< 45% as determined by echocardiography or multiple uptake gated acquisition (MUGA) scan * Any serious active disease or co-morbid medical condition (such as New York Heart Association Class III or IV cardiac disease, severe arrhythmia, myocardial infarction within the last 6 months, unstable arrhythmias, or unstable angina) or pulmonary disease (including uncontrolled obstructive pulmonary disease and history of bronchospasm or other according to investigator's decision) * Clinically significant history of liver disease, including viral or other hepatitis, current alcohol abuse, or cirrhosis * Any of the following laboratory abnormalities: * Hemoglobin \< 9 g/dL * Absolute neutrophil count (ANC) \< 1,000 cells/mm3 (1.0 G/L) unless due to lymphoma * Platelet count \< 75,000/mm3 (75 x 109/L) unless due to lymphoma * Serum glutamic-oxaloacetic transaminase (SGOT) / Aspartate Transaminase (AST) or Serum Glutamic-Pyruvate Transferase (SGPT) / Alanine Transaminase (ALT) 3.0 x upper limit of normal (ULN) unless disease involvement * Serum total bilirubin \> 2.0 mg/dL (34 μmol/L), except if disease related or in case of Gilbert syndrome * Calculated creatinine clearance (Cockcroft-Gault formula or MDRD) of \< 50 mL /min * International normalized ratio (INR) ≤ 1.5 x ULN for patients not receiving therapeutic anticoagulation * Partial thromboplastin time (PTT) or activated PTT (aPTT) \> 1.5 x ULN * Prior history of malignancies other than lymphoma unless the subject has been free of the disease for ≥ 3 years.
