About this study

Official title: A Multinational, Multicenter, Single Blood Sampling Exploratory Pharmacogenetic Study of the REGARD (the REbif® vs Glatiramer Acetate in Relapsing MS Disease) Trial

This study, REbif® vs Glatiramer acetate in relapsing multiple sclerosis (MS) disease - pharmacogenetic(s) (REGARD-PGx) is a single blood sampling exploratory pharmacogenetic study of the REGARD trial.

The aim of this trial is to provide additional data on the factors influencing interferon (IFN) beta response.

This is a Phase 4 trial involving subjects who previously participated in the REGARD trial. To address the trial objectives, a single visit follow-up trial will be performed during which a blood sample will be collected.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Blood samplingOther

    Subjects who had received Rebif® 44 microgram (mcg) three times a week for 96 weeks in study 24735 (NCT00078338) and not participated in the initial PGx sub-study will be enrolled in this retrospective cohort study wherein single blood sampling will be performed for pharmacogenetic markers analysis.

  • Blood samplingOther

    Subjects who had received Copaxone® (Glatiramer Acetate) 20 milligram once daily for 96 weeks in study 24735 (NCT00078338) and not participated in the initial PGx sub-study will be enrolled in this retrospective cohort study wherein single blood sampling will be performed for pharmacogenetic markers analysis.

What is being measured

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

  1. Percentage of Responders as Defined by Single Nucleotide Polymorphism (SNP) Markers

    A responder was defined as a participant with no multiple sclerosis (MS) relapse and no Expanded Disability Status Scale (EDSS) progression during 96 weeks in 24735 (NCT00078338). All responders were categorized on the basis of following six SNP markers: SNP1, SNP2, SNP3, SNP4, SNP5, and SNP6. Two types of variables were possible for each SNP marker: two-level genotype-based or three-level allele-based association variables. For the two-level genotype-based SNP markers (SNP2, SNP4, and SNP6), the absence or presence of the genotype was analyzed as the dichotomous variable as 0 (absence of the genotype) and 1 (presence of the genotype). For the three-level allele-based association SNP markers (SNP1, SNP3, and SNP5), the analysis was based on the number of copies of the allele (0, 1 and 2). Percentage of responders segregated on the basis of SNP marker variable were reported.

    Measured: Day 1 of EMR200136_023 study

Secondary outcomes (4)
  1. Number of Participants With Confirmed Expanded Disability Status Scale (EDSS) Progression as Defined by SNP2 Marker

    EDSS assesses disability in 8 functional systems. An overall score ranging from 0 (normal) to 10 (death due to MS) was calculated. EDSS progression was defined as increase by at least 1 point if last value of EDSS was equal to 5.5, and by at least 0.5 points if last EDSS was more than 5.5. SNP2 is two-level genotype-based SNP marker. The absence or presence of the genotype was analyzed as the dichotomous variable as 0 (absence of the genotype) and 1 (presence of the genotype). Number of responders segregated on the basis of SNP2 marker variable were reported.

    Measured: Day 1 of EMR200136_023 study

  2. Change in Time Constant 1 Gadolinium (T1 Gd) Enhancing Lesion Volume as Defined by SNP3 and SNP4 Markers

    Change in T1 Gd enhancing lesion volume was measured by using magnetic resonance imaging (MRI) scans. SNP4 is two-level genotype-based SNP marker. The absence or presence of the genotype was analyzed as the dichotomous variable as 0 (absence of the genotype) and 1 (presence of the genotype). SNP3 is a three-level allele-based association SNP markers. The analysis was based on the number of copies of the allele (0, 1 and 2). Change in T1 Gd enhancing lesion volume segregated on the basis of SNP3 and SNP4 marker variables were reported.

    Measured: Baseline (Day 1 of 24735 [NCT00078338] study) and Day 1 of EMR200136_023 study

  3. Change in Brain Volume as Defined by SNP2 Marker

    Change in brain volume was measured as the brain parenchymal fraction using MRI scans. SNP2 is two-level genotype-based SNP marker. The absence or presence of the genotype was analyzed as the dichotomous variable as 0 (absence of the genotype) and 1 (presence of the genotype). Change in brain volume segregated on the basis of SNP2 marker variables were reported.

    Measured: Baseline (Day 1 of 24735 [NCT00078338] study) and Day 1 of EMR200136_023 study

  4. Mean Number of Time Constant 2 (T2) Active Lesions Per Subject Per Scan as Defined by SNP5 Marker

    Mean number of T2 active lesions was measured by using MRI scans. SNP5 is a three-level allele-based association SNP markers. The analysis was based on the number of copies of the allele (0, 1 and 2). Mean number of T2 active lesions segregated on the basis of SNP5 marker variables were reported.

    Measured: Day 1 of EMR200136_023 study

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Blood sampling in people with Relapsing Multiple Sclerosis, run by EMD Serono at 1 site 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 2 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 10 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Mar 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Responders as Defined by Single Nucleotide Polymorphism (SNP) Markers (time frame: Day 1 of EMR200136_023 study). 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 10 Mar 2014.
