This open-label, multicenter study will evaluate the efficacy and safety of RO50 72759 (GA101) in combination with CHOP chemotherapy in patients with advanced di ffuse large B-cell lymphoma. Patients will receive 8 cycles of RO5072759 (1000 m g intravenously on Day 1 of each 21-day cycle, during Cycle 1 RO5072759 will als

o be infused on Days 8 and 15) in combination with CHOP (Cyclophosphamide, Doxor ubicin, Vincristine, Prednisone) chemotherapy during cycles 1 to 6. A substudy w ill investigate the drug-drug interaction of RO5072759 (GA101) with CHOP chemoth erapy agents. For the substudy, an additional cohort of 15 patients will be enro lled at a subset of investigational sites.

Primary Outcome Measures:
  • Complete response (CR), tumor assessments according to the Revised Response Criteria for Malignant Lymphoma (Cheson et al., 2007) [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Overall response rate (ORR: complete response + partial response) [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety: Incidence of adverse events [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of Grade 3 or 4 infusion-related adverse events in patients receiving shorter duration infusion (SDI) [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Progression-free survival: time from first RO5072759 dose to first occurrence of disease progression or relapse or death of any cause [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Duration of response (CR and OR), defined as first occurrence of CR or OR until first occurrence of relapse or progression or death of any cause [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Pharmacokinetics: area under the concentration-time curve (AUC) [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Pharmacodynamics: Peripheral blood CD19-positive B-cell count [ Time Frame: up to approximately 24 months ] [ Designated as safety issue: No ]
