Low-grade B Cell Non-Hodgkin's Lymphoma, Mantle Cell Lymphoma Where Hematopoietic Stem Cell Transplantation is Not Indicated
Conditions
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.
Interventions
DRUGSyB L-0501
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.
DRUGrituximab
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.

Overall Response Rate (PR or Better) Based on WHO Handbook for Reporting Results of Cancer Treatment (1979)
The criteria for Overall response rate (PR or better) based on WHO Handbook for Reporting Results of Cancer Treatment (1979) are shown below. Definition of PR: Measurable disease: 50% or more decrease in total tumor size of the lesions which have been measured to determine the effect of therapy by 2 observations not less than 4 weeks apart. In addition there can be no appearance of new lesions or progression of any lesion. Unmeasurable disease: Estimated decrease in tumor size of 50% or more for at least 4 weeks. Bone metastases: Partial decrease in size of lytic lesions, recalcification of lytic lesions, or decreased density of blastic lesions for at least 4 weeks.
Time frame: Up to 30 weeks
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Low-grade B-cell Non-Hodgkin's Lymphoma | Overall Response Rate (PR or Better) Based on WHO Handbook for Reporting Results of Cancer Treatment (1979) | 86.4 percentage of participants |
| Mantle Cell Lymphoma | Overall Response Rate (PR or Better) Based on WHO Handbook for Reporting Results of Cancer Treatment (1979) | 90.0 percentage of participants |
| Total | Overall Response Rate (PR or Better) Based on WHO Handbook for Reporting Results of Cancer Treatment (1979) | 87.0 percentage of participants |
Secondary
Overall Survival (OS)
Death due to any given cause was defined as an event. OS was calculated using the Kaplan-Meier estimator. The median and the 95% CI were calculated using Greenwood's formula.
Time frame: Up to 30 weeks
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Low-grade B-cell Non-Hodgkin's Lymphoma | Overall Survival (OS) | NA days |
| Mantle Cell Lymphoma | Overall Survival (OS) | NA days |
| Total | Overall Survival (OS) | NA days |
Secondary
Progression-Free Survival (PFS)
PFS is the period from registration date to the earliest onset date of any progression event calculated using the Kaplan-Meier estimator. The median and the 95% confidence interval (CI) were calculated using Greenwood's formula. Progression event was defined as progression (includes recurrence/relapse), initiation of post-study treatment, confirmation of other malignant tumor, or death due to any given cause. The date of progression was determined based on overall response assessed using IWRC, Revised RC, and WHO, and assessment by the primary physicians (excluding overall response).
Time frame: Up to 30 weeks
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Low-grade B-cell Non-Hodgkin's Lymphoma | Progression-Free Survival (PFS) | NA days |
| Mantle Cell Lymphoma | Progression-Free Survival (PFS) | NA days |
| Total | Progression-Free Survival (PFS) | NA days |
