A Japan Phase I/II Study of Bortezomib in Relapsed or Refractory Multiple Myeloma Patients

This is an interventional treatment trial for Refractory focused on measuring bolus, intravenous, proteasome inhibitor, multiple myeloma, refractory, relapse Read More

Inclusion Criteria:

• Patients diagnosed with multiple myeloma based on the predetermined diagnostic criteria
• Patients who received at least standard first-line therapy and had documentation of failure to that therapy or relapsed after remission and currently requires therapy because of progressive disease (PD) as assessed by the investigator (subinvestigator) at enrollment. There is no limitation in the number of prior therapies (salvage therapies
• Number of regimens)
• Patients with measurable disease, defined as follows: Secretory Multiple myeloma: Quantifiable serum monoclonal protein value (in general, serum M protein values of >= 1.0 g/dL of IgG and >= 0.5 g/dL of IgA.), When M protein is excreted in urine, M protein is quantitatively assayable by urinary protein electrophoresis (in general, urinary M protein excretion of >= 0.2g/day.). Non-secretory Multiple myeloma: Presence of bidimensionally measurable soft tissue masses (plasmacytomas) with a longer diameter of 2cm and more as determined by applicable radiographies (i.e. MRI, CT-scan)
• Patients with a life expectancy of >= 3 months after initiation of JNJ-26866138 therapy
• Patients with a Karnofsky Performance Status (PS, general condition) of >= 60
• Patients aged >=20 and =< 75 at enrollment in the study
• Patients who can be hospitalized at least from the initial treatment of the study drug to the completion of Cycle 1 (including the 10-day observation period after JNJ-26866138 injection - when the next cycle is delayed because the "conditions for the start of the nextcycle" were not satisfied, patients must be hospitalized until the patient satisfies the criteria (it is possible to transfer patients to treatment on an outpatient basis when the next cycle is delayed due to reasons such as schedule adjustment

Exclusion Criteria:

• Patients with plasma cell leukemia (Definition of plasma cell leukemia: A state in which the proportion of plasma cells in peripheral blood is 20%, with their absolute count being more than 2x10 ^ 9L.)
• Patients with Crow-Fukase syndrome (multiple neuritis, pigmentation, endocrine disorder, swollen organ, sclerotic bone lesion and, etc.)
• Patients with peripheral sensory neuropathy of Grade 2 or worse ("neuropathy - sensory" in NCI-CTC Japanese translation JCOG version 2) or those with neuropathic pain of Grade 2 or worse ("neurologic pain" in NCI-CTC Japanese translation JCOG version)
• Patients who underwent allogeneic hematopoietic stem cell transplantation
• Patients who underwent two or more consecutive courses of autologous peripheral blood stem cell transplantation (tandem transplantation, etc.)
• Patients suspected of having cardiac amyloidosis (patients who had a left ventricular ejection fraction (LVEF) of less than 55% by echocardiogram)
• Patients with an active infection (fever of .38ºC)
• Patients with clinical findings of pneumonia (interstitial pneumonia) or pulmonary fibrosis or those having bilateral abnormal interstitial shadows (for example, ground-glass opacities, linear opacities) on chest CT (high resolution CT), regardless of the presence or absence of associated symptoms (consultation with specialists in the respiratory system or other fields was to be held if necessary)
• Patients with a heart disease of Class III or IV on the New York Heart Association (NYHA) cardiac function classification, patients who had myocardial infarction within 6 months prior to screening, or patients with uncontrolled angina pectris, serious ventricular arrhythmia, acute ischemia, active conduction disorder, or others
• Patients with a renal disease (chronic glomerulonephritis, diabetic nephropathy, hypertensive nephropathy, gouty nephropathy, etc.) leading to the onset of impaired renal function
• Patients with uncontrolled hypertension
• Patients on pharmacotherapy (oral hypoglycemic drug or insulin preparation) for diabetes mellitus
