Brief Summary

The purpose of this study is to determine the antitumor efficacy and safety of bendamustine (SyB L-0501: 90 mg/m^2/day) for a maximum of 6 cycles (1 cycle: intravenous administration for 2 consecutive days and 26-day observation period) in patients with relapsed/refractory multiple myeloma.

Conditions

Relapsed/Refractory Multiple Myeloma

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

SyB L-0501

Group Type: EXPERIMENTAL

SyB L-0501

Intervention Type: DRUG

The administration of SyB L-0501 at 90 mg/m\^2/day by 60-minute intravenous infusion for 2 consecutive days followed by 26 days of monitoring. This is considered to be one cycle and may be repeated up to 6 times. Dose reduction or discontinuation is permitted from the second cycle as necessary according to adverse events and the results of monitoring during the previous cycle.

Eligibility Criteria

Inclusion Criteria

(definition of progression according to the IMWG response criteria)

• 25% or more increase compared to baseline for the following values

• Serum M-protein level (however, the absolute value is 0.5 g/dL or higher)
• Urine M-protein level (however, absolute value is 200 mg/24 hours or higher)
• For lesions without measurable serum or urine M-protein values. involved/uninvolved free light chain (FLC) ratio (however, absolute value is 10 mg/dL or higher)
• Clear appearance of new bone lesions or soft tissue plasmacytoma or apparent growth in size of current bone lesions or soft tissue plasmacytoma

• Serum creatinine: < than 3.0 times the upper limit of normal range for the site
• Partial pressure of O2 (PaO2) ≥ 65 mmHg
• No abnormalities which require treatment are detected on ECG
• Left ventricular ejection fraction (LVEF)(echocardiography): ≥ 55%

9. Patients who have provided written consent for participation in this study
