Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- Patient is of a legally consenting age, as defined by local regulations.
- Patient is, in the investigator's opinion, willing and able to comply with the protocol requirements.
- Patient has given voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care.
- Female patient is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study.
- Male patient agrees to use an acceptable method for contraception for the duration of the study.
- Patient was previously diagnosed with multiple myeloma based on standard criteria and currently requires second-, third-, or fourth-line therapy because of PD, defined as a 25% increase in M-protein, development of new or worsening of existing lytic bone lesions or soft tissue plasmacytomas, or hypercalcemia (serum calcium >11.5 mg/dL), or relapse from CR.

- Patient has measurable disease, defined as follows:
- For secretory multiple myeloma, measurable disease is defined as any quantifiable serum monoclonal protein value (generally, but not exclusively, greater than 1 g/dL of IgG M-Protein and greater than 0.5g/dL IgA) and, where applicable, urine light-chain excretion of ≥200 mg/24 hours.
- For oligo- or non-secretory multiple myeloma, measurable disease is defined by the presence of soft tissue (not bone) plasmacytomas as determined by clinical examination or applicable radiographs (i.e. MRI, CT-Scan). In patients with oligosecretory multiple myeloma, the serum and/or urine M-protein measurements are very low and difficult to follow for response assessments. Therefore, other disease sites (bone marrow; extramedullary mass) must be assessed and followed. In patients with non-secretory multiple myeloma, there is no M-protein in serum or urine by immunofixation.
- Patient has a Karnofsky performance status ≥60%.
- Patient has a life-expectancy >3 months.
- Patient has the following laboratory values at and within 14 days before Baseline (Day 1 of Cycle 1, before study drug administration):
- Platelet count ≥50 x 10E+9/L without transfusion support within 7 days before the laboratory test.
- Hemoglobin ≥7.5 g/dL, without transfusion support within 7 days before the laboratory test.
- Absolute neutrophil count (ANC) ≥0.75 x 10E+9/L without the use of colony stimulating factors.
- Corrected serum calcium <14 mg/dL (3.5 mmol/L).
- Aspartate transaminase (AST): ≤2.5 x the upper limit of normal (ULN).
- Alanine transaminase (ALT): ≤2.5 x the ULN.
- Total bilirubin: ≤1.5 x the ULN.
- Calculated or measured creatinine clearance: ≥20 mL/minute.
Who cannot join
- Patient previously received treatment with VELCADE.
- Patient previously was refractory to treatment with high-dose dexamethasone, as experiencing less than a partial response to or PD within 6 months after discontinuing dexamethasone, or discontinued dexamethasone because of ≥Grade 3 dexamethasone-related toxicity.
- Previous high-dose dexamethasone therapy is defined as >500 mg dexamethasone or equivalent over a 10-week period, whether administered alone or as part of the VAD regimen.
- Patient received nitrosoureas within 6 weeks or any other chemotherapy, including thalidomide or clarithromycin, or radiation therapy within 3 weeks before enrollment.
- Patient received corticosteroids (>10 mg/day prednisone or equivalent) within 3 weeks before enrollment.
- Patient received immunotherapy or antibody therapy within 8 weeks before enrollment.
Show all 22Show fewer
- Patient received plasmapheresis within 4 weeks before enrollment.
- Patient had major surgery within 4 weeks before enrollment. (Kyphoplasty is not considered major surgery.)
- Patient has a history of allergic reaction attributable to compounds containing boron or mannitol.
- Patient has peripheral neuropathy of Grade 2 or greater intensity, as defined by the NCI Common Toxicity Criteria (NCI CTC):
- Grade 2: Objective sensory loss or paresthesia (including tingling), interfering with function, but not interfering with activities of daily living (ADLs).
- Grade 3: Sensory loss or paresthesia interfering with ADLs.
- Grade 4: Permanent sensory loss that interferes with function.
- Patient had a myocardial infarction within 6 months of enrollment or has New York Heart Association (NYHA) Class III or IV heart failure uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
- Patient was treated for a cancer other than multiple myeloma within 5 years before enrollment, with the exception of basal cell carcinoma or cervical cancer in situ.
- Patient has cardiac amyloidosis.
- Patient has poorly controlled hypertension, diabetes mellitus, or other serious medical or psychiatric illness that could potentially interfere with the completion of treatment according to this protocol.
- Patient is known to be human immunodeficiency virus (HIV)-positive. (Patients assessed by the investigator to be at risk for HIV infection should be tested in accordance with local regulations.)
- Patient is known to be hepatitis B surface antigen-positive or has known active hepatitis C infection.
- Patient has an active systemic infection requiring treatment.
- Female patient is pregnant or breast-feeding.
- Patient currently is enrolled in another clinical research study and/or is receiving an investigational agent for any reason.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing bortezomib in people with Multiple Myeloma, run by Millennium Pharmaceuticals, Inc. at 93 sites in 13 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 20 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 93 sites in United States, Germany, France, Belgium, United Kingdom and 8 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00048230, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2012.
