Description
Key Inclusion Criteria:
- Relapsed or refractory multiple myeloma that was treated with or was considered inappropriate for treatment with bortezomib and an IMiD® drug (including an analogue).
- Eastern Cooperative Oncology Group (ECOG) Performance Status ≤2.
- Corrected calcium <10.6 mg/dL.
Key Exclusion Criteria:
- Candidates for stem cell transplantation willing to undergo transplantation. (Subjects who are candidates for stem cell transplantation, but are not willing to undergo transplant will be eligible for the study.)
- Autologous stem cell transplantation <3 months post-transplant.
- Prior allogeneic stem cell transplantation.
- Nonsecretory myeloma.
- Plasma cell leukemia (>2000/µL circulating plasma cells by standard cell counting differential), hyperleukocytosis (white blood cells >100,000/µL), clinical evidence of hyperviscosity syndrome, or polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes syndrome (POEMS), or primary systemic amyloidosis.
- Subjects who cannot undergo a brain magnetic resonance imaging (MRI) study.
- Clinically significant (as determined by the Investigator) 12 lead electrocardiogram (ECG) abnormalities, including QTc prolongation (>450 ms in males, >470 ms in females).
NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

Measure Description |
Time Frame |
|---|---|---|
|
Number of Participants With Dose Limiting Toxicities (DLTs)
Time Frame: Day 1 up to Day 28
|
DLTs = any ≥grade 3 toxicity related to treatment; treatment delays of ≥7 days due to any toxicity related to treatment, with the exception of hepatic transaminases; or alanine and/or aspartate aminotransferase (ALT and/or AST) >3*upper limit of normal (ULN) with either a total bilirubin >2*ULN or an international normalized ratio (INR) >1.5 related to treatment, or with the appearance of worsening fatigue, nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, or eosinophilia.
|
Day 1 up to Day 28
|
|
Objective Response Rate (ORR)
Time Frame: Day 1 up to Month 6
|
Response rates were classified according to the International Uniform Response Criteria for Multiple Myeloma (Durie et al, 2006).
|
Day 1 up to Month 6
|
|
Number of Participants With Adverse Events (AEs)
Time Frame: Day 1 up to Month 6
|
An AE was defined as any untoward medical occurrence in a participant administered medicinal (investigational) product and that does not necessarily have a causal relationship with this product.
An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
See the adverse events section of the record for more details.

Number Of Participants Who Achieve A Complete Response
Time Frame: Day 1 up to Month 6
|
Response rates were classified according to the International Uniform Response Criteria for Multiple Myeloma (Durie et al, 2006).
Complete Response (CR): negative immunofixation on the serum and urine, and disappearance of any soft tissue plasmacytomas , and ≤ 5% plasma cells in the bone marrow.
Stringent CR (sCR): CR as defined above, and normal free light chain (FLC) ratio, and absence of clonal cells in the bone marrow by immunohistochemistry or immunofluorescence, based on a κ/λ ratio of > 4:1 or < 1:2 performed on a minimum of 100 plasma cells.
|
Day 1 up to Month 6
|
|
Kaplan-Meier Estimates for Duration Of Response For Participants With A Response
Time Frame: Day 1 up to Month 6
|
Response rates were classified according to the International Uniform Response Criteria for Multiple Myeloma (Durie et al, 2006).
Kaplan-Meier methods were used to estimate the median duration of response and associated 95% confidence intervals.
|
Day 1 up to Month 6
|
|
Pharmacokinetic (PK) Profile Of Natalizumab
Time Frame: Cycles 1 and 6: Day 1 (before infusion and 0.25, 2, 6 and 24 hours after infusion), Days 8, 15, 22. Cycles 2-5: Day 1 (before infusion and 0.25 hour after infusion)
|
PK modeling, either compartmental or noncompartmental-based, was used to describe serum concentrations.
Standard PK parameters estimated include: area-under-the-concentration-time curve (AUC), maximum-observed concentration (Cmax), time-to-reach maximum concentration (Tmax), total body clearance (Cl), volume of distribution (Vd), and elimination half-life (t1/2).
|
Cycles 1 and 6: Day 1 (before infusion and 0.25, 2, 6 and 24 hours after infusion), Days 8, 15, 22. Cycles 2-5: Day 1 (before infusion and 0.25 hour after infusion)

Natalizumab Binding Saturation Of α4 Integrin Sites On Peripheral Blood Mononuclear Cells (PBMC)
Time Frame: Cycle 1: Day 1 (1 hour before infusion and 1 and 24 hours after infusion), Days 8, 15, 22. Cycles 2-5: 1 hour before and 1 hour after infusion). Cycle 6: Day 1 (1 hour before infusion and 1 hour after infusion), Days 8, 15, 22.
|
Cycle 1: Day 1 (1 hour before infusion and 1 and 24 hours after infusion), Days 8, 15, 22. Cycles 2-5: 1 hour before and 1 hour after infusion). Cycle 6: Day 1 (1 hour before infusion and 1 hour after infusion), Days 8, 15, 22.
