About this study

Official title: A Randomized, Open-Label, Dose-Ranging Study to Evaluate the Pharmacokinetics and Initial Safety of Subcutaneous and Intramuscular Natalizumab in Subjects With Multiple Sclerosis

The primary objective of this study is to compare the pharmacokinetic (PK) and pharmacodynamics (PD) of single subcutaneous (SC) and intramuscular (IM) doses of 300 mg natalizumab to intravenous (IV) administration of 300 mg natalizumab in multiple sclerosis (MS) participants. The secondary objectives are to investigate the safety, tolerability and PK of repeated natalizumab doses administered SC and IM, to investigate the immunogenicity of repeated natalizumab doses administered SC and IM, to explore proof of concept within the secondary progressive multiple sclerosis (SPMS) population using change from baseline in clinical measures including: expanded disability status scale (EDSS), multiple sclerosis functional composite scale (MSFC), symbol digit modalities test (SDMT), visual analogue scale (VAS), and visual function test; and brain magnetic resonance imaging (MRI) measures including: number of new or newly-enlarging T2 hyperintense lesions, number of new T1 hypointense lesions, number of new gadolinium-enhancing (Gd+) lesions, whole brain atrophy, magnetization transfer ratio (MTR), and diffusion tensor imaging (DTI) and to observe the effect of natalizumab administered IV and SC on brain MRI measures in participants with relapsing forms of MS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum observed concentration (Cmax) of natalizumab

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

  2. Time to maximum observed concentration (Tmax) of natalizumab

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

  3. Area under the curve to the last measurable concentration (AUC0-last) of natalizumab

    Area under the curve to the last measurable concentration as measured by the trapezoidal rule.

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

  4. Apparent volume of distribution of natalizumab

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

  5. Half-life of natalizumab

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

  6. Area under the curve extrapolated to infinity (AUC0-∞) of natalizumab

    Measured: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

    Measured: Pre-dose, 4, 24 and 72 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56

Secondary outcomes (17)
  1. Number of Participants with adverse events

    Measured: 13-19 months

  2. Number of participants with abnormalities in vital signs

    Measured: 13-19 months

  3. Number of participants with changes in the physical examination

    Measured: 13-19 months

  4. Number of participants with abnormal laboratory test results

    Measured: 13-19 months

  5. Number of participants with natalizumab antibodies

    Measured: Days 28, 42, 56, Weeks 24 and 32

  6. Change from Baseline in expanded disability status scale (EDSS)

    The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist.

    Measured: Baseline, Weeks 8, 20, and 32

  7. Change form Baseline in Multiple Sclerosis Functional Composite Scale (MFSC)

    The MFSC consists of 3 tests: 1. Timed 25-Foot Walk, a quantitative mobility and leg function performance test where the participant is timed while walking for 25 feet; 2. 9-Hole Peg Test (9HPT), a quantitative test of upper extremity function that measures the time it takes to place 9 pegs into 9 holes and then remove the pegs. 3. 3 Second Paced Auditory Serial Addition Test (PASAT 3). The MSFC is based on the concept that scores for these 3 dimensions - arm, leg, and cognitive function are combined to create a single score that can be used to detect change over time. A composite z-score is created, which represents the number of standard deviations (SDs) a participant's test result is higher (z > 0) or lower (z < 0) than the average test result (z = 0) of the reference population.

    Measured: Baseline, Weeks 8, 20, and 32

  8. Change from Baseline in Symbol Digit Modalities Test (SDMT)

    SDMT is a screening test for cognitive impairment. Participants are given 90 seconds in which to pair specific numbers with given geometric figures using a key. Scores range from 0 to 110 (best).

    Measured: Baseline, Weeks 8, 20, and 32

  9. Change from Baseline in visual analog scale (VAS)

    The participant's global assessment of well-being as assessed using a visual analogue scale (VAS) is a quality of life measurement that will be evaluated for the specified time periods. Participants report how they feel on a scale of 0 to 100, where 0 indicates being "poor" and 100 being "excellent."

    Measured: Baseline, Weeks 8, 20, and 32

  10. Change from Baseline in visual function test

    Measured: Baseline, Weeks 8, 20, and 32

  11. Number of new or newly enlarging T2 hyperintense lesions

    Measured by magnetic resonance imaging (MRI).

    Measured: Baseline and Week 32

  12. Number of new gadolinium-enhanced lesions

    Measured by magnetic resonance imaging (MRI).

    Measured: Baseline and Week 32

  13. Number of new T1 hypointense lesions

    Measured by magnetic resonance imaging (MRI).

    Measured: Baseline and Week 32

  14. Whole brain atrophy

    Atrophy will be measured as the percent brain volume change (PBVC) and will be assessed using the Structural Image Evaluation of Normalized Atrophy (SIENA).

    Measured: Baseline and Week 32

  15. Percent change in magnetization transfer ratio (MTR)

    Remyelination will be measured using magnetization transfer ratio (MTR) in whole brain (WB) and normal-appearing brain tissue (NABT),

    Measured: Baseline and Week 32

  16. Diffusion tensor imaging (DTI)

    Measured: Baseline and Week 32

  17. Injection site pain assessment

    Measured: Pre-dose, 5 and 15 minutes and 24 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing natalizumab in people with Relapsing-Remitting Multiple Sclerosis and Secondary Progressive Multiple Sclerosis, run by Biogen at 12 sites in United States.

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 3 inclusion and 3 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 9 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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.

What does the primary outcome measure?

Maximum observed concentration (Cmax) of natalizumab (time frame: Pre-dose, 4, 24, 48, 72 and 96 hours post-dose and Days 7, 14, 21, 28, 35, 42 and 56). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Sep 2014.
