Interventions

SyB L-0501DRUG

SyB L-0501 (150 mg/m2/day) will be administered by intravenous drip infusion for 60 min for 2 consecutive days and the course will be observed for the next 26 days. This is taken as one cycle and administration is repeated for 2-9 cycles (when a plateau is not reached after nine cycles, administration of up to an additional three cycles for a maximum of 12 cycles is possible).

prednisoloneDRUG

Prednisolone will be administered (60 mg/m2/day) orally for 4 consecutive days and the course will be observed for the next 24 days.

Inclusion Criteria: Patients are included in the study if all of the following criteria are met: Patients confirmed to have multiple myeloma (symptomatic myeloma) defined in the diagnostic criteria of the International Myeloma Working Group (IMWG). * Patients with measurable lesions * Patients with no history of treatment (no history of chemotherapy or radiotherapy) * Patients should not be considered candidates for high dose therapy/autologous stem cell transplantation due to coexistent medical conditions, advanced age, poor performance status, refusal of high dose chemotherapy, or other reasons as judged by the patient and/or physician. * Expected survival of at least 3 months * Patients aged between 20 and 79 years (at the time of provisional registration) * Performance status (P.S.) grade 0-2. P.S. 3 possible only for osteolytic lesions * Patients with adequately maintained organ function (e.g., bone marrow, heart, lungs, liver, kidneys,) * Patients from whom written consent to participate in this study has been obtained. Exclusion Criteria: Patients are excluded from participating in the study if 1 or more of the following criteria are met: * Patients with apparent infections (including viral infections) * Patients with serious complications (hepatic failure, renal failure, or diabetes with insulin administration) * Patients with complications or a medical history of serious cardiac disease (e.g., myocardial infarction, ischemic heart disease) within 2 years before preliminary registration. Patients with arrhythmia requiring treatment. * Patients with serious gastrointestinal symptoms (profound or serious nausea / vomiting or diarrhea, etc.) * Patients who were hepatitis B virus antigen (HBsAG)-positive, hepatitis C virus (HCV) antibody-positive or human immunodeficiency virus (HIV) antibody-positive * Patients with a serious bleeding tendency \[e.g., Disseminated intravascular coagulation (DIC)\] * Patients with interstitial pneumonia, pulmonary fibrosis or pulmonary emphysema requiring treatment, or such diseases in the past * Patients with apparent amyloidosis as a complication * Patients with clinical symptoms of invasion or suspected invasion of the central nervous system. * Patients with active multiple cancers * Patients who have or previously had autoimmune hemolytic anemia. * Patients administered this investigational drug in the past * Patients who received hematopoietic stem cell transplantation in the past. * Patients who received cytokines such as granulocyte colony stimulating factor (G-CSF) or erythropoietin or a blood transfusion within 1 week before the screening examination prior to preliminary registration for this study * Patients who were administered an investigational drug during a clinical study or an unapproved drug within 3 months prior to preliminary registration in this study * Patients with prior allergies to medications similar to the investigational drug (e.g., alkylating agents, or purine nucleotide analogs), mannitol or prednisolone * Patients with drug addiction, narcotic addiction or alcoholism. * Patients who were pregnant, breastfeeding women or who had a possibility to be pregnant * Patients who do not agree to contraception during the following periods. For males, during or for 6 months after completion of administration of the investigational drug. For females, during or for 3 months after completion of administration of the investigational drug * Patients whom the investigator or the sub-investigators considered to be inappropriate for the study

Outcomes

Primary Outcomes

Complete Response (CR) Rate [Based on the Modified Southwest Oncology Group (SWOG) Criteria]

The proportion of subjects evaluated as CR was calculated. CR (modified SWOG) requires all of the followings: 1. Decline in serum myeloma protein by ≥75% to ≤25 g/L 2. Reduction in 24 h urinary protein by ≥90% to ≤200 mg/24 h 3. No increase in skeletal destruction 4. Serum calcium within normal range 5. No blood transfusion required in the previous 3 months

Time frame: Up to 36 weeks

Secondary Outcomes

CR Rate [Based on the International Myeloma Working Group (IMWG) Criteria]

The proportion of subjects evaluated as CR \[strict CR (sCR) + CR\] was calculated. sCR (IMWG): CR as defined below plus Normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence CR (IMWG): Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \<5% plasma cells in bone marrow

Time frame: Up to 36 weeks

Response Rate (Based on the IMWG Criteria)

The proportion of subjects evaluated as response \[sCR + CR + very good partial response (VGPR) + Partial Response (PR)\] was calculated. VGPR (IMWG): Serum and urine M-protein detectable by immunofixation but not on electrophoresis or 90% or greater reduction in serum M-protein plus urine M-protein level \<100mg per 24 h PR (IMWG): ≥50% reduction of serum M-protein and reduction in 24 h urinary M-protein by ≥90% or to \<200mg per 24 h

Time frame: Up to 36 weeks

CR Rate Based on the (Bladé) Criteria

The proportion of subjects evaluated as CR was calculated. CR (Bladé) requires all of the followings: 1. Absence of the original monoclonal paraprotein in serum and urine by immunofixation, maintained for a minimum of 6 weeks. The presence of oligoclonal bands consistent with oligoclonal immune reconstitution does not exclude CR. 2. \<5% plasma cells in a bone marrow aspirate and also on trephine bone biopsy, if biopsy is performed. If absence of monoclonal protein is sustained for 6 weeks it is not necessary to repeat the bone marrow, except in patients with non-secretory myeloma where the marrow examination must be repeated after an interval of at least 6 weeks to confirm CR. 3. No increase in size or number of lytic bone lesions (development of a compression fracture does not exclude response) 4. Disappearance of soft tissue plasmacytomas
