efficacy and safety study of syb l-0501 in combination with rituximab in patients with untreated, low-grade b cell non-hodgkin's lymphoma and mantle cell lymphoma

Conditions: Low-grade B Cell Non-Hodgkin's Lymphoma; Mantle Cell Lymphoma Where Hematopoietic Stem Cell Transplantation is Not Indicated

Summary: the purpose of this study is to assess the efficacy and safety of syb l-0501 (two-day consecutive 90 mg/m2/day iv drip infusions) in combination with rituximab (375 mg/m2 iv drip infusion) on untreated, low-grade b cell non-hodgkin's lymphoma and mantle cell lymphoma where hematopoietic stem cell transplantation is not indicated.
