About this study

Official title: A Randomized, Double-Blind, Double-Dummy, Parallel-Group Study To Evaluate the Efficacy and Safety of Ocrelizumab in Comparison to Interferon Beta-1a (Rebif) in Patients With Relapsing Multiple Sclerosis

This randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with interferon beta-1a (Rebif) in participants with relapsing multiple sclerosis. Participants will be randomized to receive either ocrelizumab 600 mg or matching placebo intravenous (IV) as 300 mg infusions on Days 1 and 15 for the first dose and as a single infusion of 600 mg for all subsequent infusions every 24 weeks, with placebo injections matching interferon beta-1a SC three times per week; or interferon beta-1a 44 mcg SC injections three times per week (with placebo infusions matching ocrelizumab infusions every 24 weeks).

Being tested

Receives: Drug: Ocrelizumab; Drug: Interferon beta-1a-matching placebo

What is being measured

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

  1. Annualized Relapse Rate (ARR) in Participants With Relapsing Multiple Sclerosis (MS) at 96 Weeks In Double Blind Period

    ARR was protocol-defined and calculated as the total number of relapses for all participants in the treatment group divided by the total participant-years of exposure to that treatment.

    Measured: Week 96

Secondary outcomes (13)

  1. Time to Onset of Confirmed Disability Progression (CDP) for at Least 12 Weeks During the Double-Blind Treatment Period

    Disability progression was defined as an increase in the Expanded Disability Status Scale (EDSS) score of: A) >=1.0 point from the baseline EDSS score when the baseline score was less than or equal to (<=) 5.5 B) >=0.5 point from the baseline EDSS score when the baseline score was >5.5 The EDSS scale ranges from 0 (normal neurological exam) to 10 (death due to multiple sclerosis). This outcome measure was considered confirmatory only when results of both studies WA21092 and WA21093 were combined. Disability progression was considered confirmed when the increase in the EDSS was confirmed at a regularly scheduled visit at least 12 weeks after the initial documentation of neurological worsening. Participants who had initial disability progression with no confirmatory EDSS assessment and who were on treatment at time of clinical cut-off date were censored at the date of their last EDSS assessment.

    Measured: Week 104

  2. Number of T1 Gadolinium (Gd)-Enhancing Lesions as Detected by Brain Magnetic Resonance Imaging (MRI) During the Double-Blind Treatment

    The total number of T1 gadolinium-enhancing lesions for all participants in the treatment group was calculated as the sum of the individual number of lesions at Weeks 24, 48, and 96.

    Measured: Baseline up to week 96

  3. Number of New, and/or Enlarging T2 Hyperintense Lesions as Detected by Brain Magnetic Resonance Imaging (MRI) During the Double Blind Treatment

    The total number of new and/or enlarging T2 lesions for all participants in the treatment group was calculated as the sum of the individual number of lesions at Weeks 24, 48, and 96.

    Measured: Baseline up to week 96

  4. Percentage of Participants With Confirmed Disability Improvement (CDI) for at Least 12 Weeks In Double Blind Period

    Disability improvement was assessed only for the subgroup of participants with a baseline EDSS score of >= 2.0. It was defined as a reduction in EDSS score of: A) >=1.0 from the baseline EDSS score when the baseline score was >=2 and <=5.5 B) >= 0.5 when the baseline EDSS score > 5.5. The EDSS scale ranges from 0 (normal neurological exam) to 10 (death due to multiple sclerosis). This outcome measure was considered confirmatory only when results of both studies WA21092 and WA21093 were combined.

    Measured: Week 96

  5. Time to Onset of Confirmed Disability Progression (CDP) for at Least 24 Weeks During the Double-Blind Treatment Period

    Disability progression was defined as an increase in the Expanded Disability Status Scale (EDSS) score of: A) >=1.0 point from the baseline EDSS score when the baseline score was less than or equal to (<=) 5.5 B) >=0.5 point from the baseline EDSS score when the baseline score was >5.5 The EDSS scale ranges from 0 (normal neurological exam) to 10 (death due to multiple sclerosis). This outcome measure was considered confirmatory only when results of both studies WA21092 and WA21093 were combined. Disability progression was considered confirmed when the increase in the EDSS was confirmed at a regularly scheduled visit at least 24 weeks after the initial documentation of neurological worsening. Participants who had initial disability progression with no confirmatory EDSS assessment and who were on treatment at time of clinical cut-off date were censored at the date of their last EDSS assessment.

    Measured: Week 104

  6. Number of T1 Hypointense Lesions During the Double-Blind Treatment

    The total number of new T1-Hypo-Intense Lesions (Chronic Black Holes) for all participants in the treatment group was calculated as the sum of the individual number of new lesions at Weeks 24, 48, and 96.

    Measured: Baseline up to week 96

  7. Change From Baseline in Multiple Sclerosis Functional Composite (MSFC) Score to Week 96 In Double Blind Period

    MSFC score consists of: A) Timed 25-Foot walk; B) 9-Hole Peg Test (9-HPT); and C) Paced Auditory Serial Addition Test (PASAT-3 version). The MSFCS is based on the concept that scores for these three dimensions (arm, leg, and cognitive function) are combined to create a single score (the MSFC) that can be used to detect change over time in a group of participants with MS. Since the three primary measures differ in what they actually measure, a common composite score for the three different measures i.e., Z- score was selected for the purpose. MSFC Score = {Z arm, average + Z leg, average + Z cognitive} / 3.0. The results from each of these three tests are transformed into Z-scores and averaged to yield a composite score for each participant at each time point. A score of +1 indicates that, on average, an individual scored 1 standard deviation (SD) better than the reference population and a score of -1 indicates that an individual scored 1 SD worse than the reference population.

    Measured: Baseline, Week 96

  8. Percent Change in Brain Volume as Detected by Brain Magnetic Resonance Imaging (MRI) From Week 24 to Week 96 In Double Blind Period

    Brain volume was recorded as an absolute "normalized" value at the baseline visit then recorded at subsequent visits as a percentage change relative to the absolute value at the baseline visit. Therefore, brain volume at Week 24 was calculated as the brain volume at the baseline visit multiplied by 1 + ([percentage change in brain volume from baseline visit to Week 24]/100). Estimates are from analysis based on mixed-effect model of repeated measures (MMRM) using unstructured covariance matrix: Percentage Change = Brain Volume at Week 24 + Geographical Region (US vs. ROW) + Baseline EDSS (< 4.0 vs. >= 4.0) + Week + Treatment + Treatment*Week (repeated values over Week) + Brain Volume at Week 24*Week. The EDSS scale ranges from 0 (normal neurological exam) to 10 (death due to multiple sclerosis).

    Measured: From week 24 up to week 96

  9. Change From Baseline in Short Form Health Survey-36 (SF-36) Physical Component Summary (PCS) Score at Week 96 In Double Blind Period

    The SF-36 is a multi-purpose, short-form health survey with 36 questions. It yields an 8-scale profile of functional health and well-being scores (domains) as well as psychometrically based physical and mental health summary measures. The SF-36 taps 8 health concepts: physical functioning, bodily pain, physical role functioning, emotional role functioning, emotional well-being, social functioning, vitality, and general health perceptions. The 8 scales are further summarized to 2 distinct higher-ordered clusters: the PCS and mental composite t-score (MCS). The range for all 8 domains as well as for the composite t- scores is from 0 to 100 with 100 as best possible health status and 0 as worst health status.

    Measured: Baseline, Week 96

  10. Percentage of Participants Who Have No Evidence of Disease Activity (NEDA) up to Week 96 In Double Blind Period

    NEDA was defined only for participants with a baseline EDSS score >=2.0. The EDSS scale ranges from 0 (normal neurological exam) to 10 (death due to multiple sclerosis). Participants who completed the 96- week treatment period were considered as having evidence of disease activity if at least one protocol- defined relapse (PDR), a confirmed disability progression (CDP) event or at least one MRI scan showing MRI activity (defined as Gd-enhancing T1 lesions, or new or enlarging T2 lesions) was reported during the 96-week treatment period, otherwise the participant was considered as having NEDA.

    Measured: Week 96

  11. Number of Participants With Adverse Events (AEs)

    AEs included infusion related reactions (IRRs) and serious MS relapses, but excluded non-serious MS relapses. Serious Adverse Events (SAEs) included serious MS relapses and serious IRRs.

    Measured: Baseline up to Week 96

  12. Exposure to Ocrelizumab (Area Under the Concentration - Time Curve, AUC) In Double Blind Period

    AUC represents total drug exposure for one dosing interval after the 4th dose.

    Measured: Pre-infusion at Weeks 1, 24, 48, 72; and 30 minutes post-infusion at Week 72; at any time during Weeks 84 and 96

  13. Number of Participants With Anti-Drug Antibodies (ADAs) to Ocrelizumab In Double Blind Period

    Number of participants positive for anti-drug antibodies (ADAs) to ocrelizumab is the number of post- baseline evaluable participants determined to have treatment-induced ADA or treatment-enhanced ADA during the study period.

    Measured: Baseline up to Week 96

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Interferon beta-1a and Ocrelizumab in people with Relapsing Multiple Sclerosis, run by Hoffmann-La Roche at 165 sites in 24 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 4 inclusion and 12 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 8 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 165 sites in United States, Germany, Italy, Spain, Poland and 19 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?

Yes. Results are posted in the registry (first posted 18 Jul 2017). 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?

Annualized Relapse Rate (ARR) in Participants With Relapsing Multiple Sclerosis (MS) at 96 Weeks In Double Blind Period (time frame: Week 96). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01412333, which also lists 16 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 8 Mar 2024; AzTrials last refreshed its copy on 6 Nov 2026.
