A Phase II, Open-Label, Multicenter Study of Efficacy, Safety, and Biomarkers in Patients With Previously Untreated Advanced Diffuse Large B-Cell Lymphoma Treated With GA101 (RO5072759) in Combination With CHOP Chemotherapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This open-label, multicenter study will evaluate the efficacy and safety of obinutuzumab \[RO5072759 (GA101)\] in combination with CHOP (Cyclophosphamide, Doxorubicin, Vincristine, Prednisone) chemotherapy in patients with advanced diffuse large B-cell lymphoma. Patients will receive 8 cycles of obinutuzumab (1000 mg intravenously on Day 1 of each 21-day cycle, during Cycle 1 obinutuzumab will also be infused on Days 8 and 15) in combination with CHOP chemotherapy on Day 1 of cycles 1 to 6. A substudy will investigate the drug-drug interaction of obinutuzumab with CHOP chemotherapy agents. For the substudy, an additional cohort of approximately 15 patients are planned to be enrolled at a subset of investigational sites.
