Enrollment: 70
Healthy volunteers: no

Brief 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.

Detailed description:

Arms:
arm 1: None

Interventions: intervention 1: SyB L-0501 intervention 2: rituximab
Intervention descriptions: intervention 1: A dose of 90 mg/m\^2/day of SyB L-0501 is administered on Day 1 and Day 2 as an IV drip infusion, followed by 26-day observation. This is 1 cycle (28 days), which will be repeated for a maximum of 6 times. intervention 2: A dose of 375 mg/m\^2 of rituximab is administered on Day 1 (Day 0 in Cycle 1 only) as an IV drip infusion, followed by 26-day observation. This is 1 cycle (28 days), which will be repeated for a maximum of 6 times. From Cycle 2, rituximab will be coadministered with SyB L-0501 on Day 1. However, if the investigator or sub-investigator judges that the coadministration is difficult, rituximab may be administered on Day 0.
