A Study of Bevacizumab (Avastin) in Combination With Rituximab (MabThera) and CHOP (Cyclophosphamide, Hydroxydaunorubicin [Doxorubicin], Oncovin [Vincristine], Prednisone) Chemotherapy in Patients With Diffuse Large B-cell Lymphoma
Summary
This 2-arm study was designed to compare the efficacy and safety of bevacizumab (Avastin) in combination with rituximab (MabThera) and CHOP (cyclophosphamide, hydroxydaunorubicin \[doxorubicin\], Oncovin \[vincristine\], prednisone) chemotherapy (R-CHOP) versus rituximab plus CHOP chemotherapy (R-CHOP) in previously untreated patients with CD20-positive diffuse large B-cell lymphoma (DLBCL). Patients were randomized to receive 8 cycles of treatment with R-CHOP plus bevacizumab or R-CHOP plus placebo. Treatment with bevacizumab/placebo and R-CHOP was given either on a 2-week or 3-week schedule and bevacizumab was given at a weekly average dose of 5 mg/kg (10 mg/kg for 2-week cycles and 15 mg/kg for 3-week cycles).
