Who cannot join

  • Diagnosis of Progressive MS
  • Previous treatment with any "second-line" immunomodulatory drug, eg natalizumab, alemtuzumab, fingolimod, or other long-acting immunosuppressive agents.

  • Patients having contraindication for or otherwise not compliant with MRI investigations
  • Simultaneous treatment with other immunosuppressive drugs
  • Active, severe infections Signs of infections are assessed before inclusion and each study-related infusion through clinical examination and further evaluated by laboratory and other relevant investigations in case of suspected ongoing infection. Hepatitis serology (HBsAg and anti-HBc) will be evaluated before treatment onset if not tested within the previous three years.
Show all 10Show fewer
  • Severe cardiac disorder, e.g signs of congestive heart failure or coronary artery disease. This will be evaluated through clinical assessment before inclusion.
  • Vaccination within 4 weeks of first dose of study medication.
  • Documented allergy or intolerance to the IP

About this study

Official title: RItuximab Long-Term DOSE Trial in Multiple Sclerosis - RIDOSE-MS. A Randomized Trial of Long-term Dosage of Rituximab in Multiple Sclerosis

A randomized trial of long-term dosage of rituximab in multiple sclerosis

Read the detailed description

This is a prospective randomized phase 3 study comparing two dosing regimens of Rituximab in long-term treatment of MS. Primary endpoint is no evidence of disease activity (NEDA) in a non-inferiority analysis between 12-months dosing interval of 500 mg rituximab with 6-months dosing interval. The endpoint is a compound of being free from release, new or enlarging MRI lesions and sustained progression of disability measured by EDSS.

Each patient will have one treating physician responsible for all ongoing medical questions and decisions regarding continuation in the study and one examining physician performing the blinded Expanded Disability Status Scale examination and assessments of exacerbations. The coordinating nurse will administer the study-related tests and administer the rituximab infusions. MRI investigations will be performed blinded for the dosing arm allocation.

Randomization will be performed via a randomization module in the national Swedish MS registry. The patients will be randomized in a 1:1 ratio and receive their treatments in accordance with clinical practice. Thus, the study will mimic the real-life situation in which the treatments will be administered. This will lead to a high degree of validity in relation to expected outcome in clinical practice.

What participants receive

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

  • RituximabDrug

    Also called Mabthera

    After one year in the trial, the patients are split in the two dosing-arms described above. The dose-comparison phase continues four years.

What is being measured

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

  1. No evidence of disease activity (NEDA)

    The proportion of patients maintaining No Evidence of Disease Activity-3 (NEDA-3) during year 2 - 4 of the trial: No relapse, no new T2 lesions (> 3 mm), no EDSS progression in either dose arm

    Measured: 3 years

Secondary outcomes (11)
  1. No evidence of disease activity (NEDA) in subgroups

    The proportion of patients maintaining NEDA-3 comparing the previous rituximab arm with the previous DMF arm from the RIFUND trial

    Measured: 4 years

  2. Time to first relapse

    Time to first relapse for the two dose arms

    Measured: 3 yeas

  3. Freedom of new or enlarged lesions on MRI

    Proportion of patients in each dosing arm without new/enlarging T2 lesions

    Measured: 3 years

  4. Development of brain atrophy

    Evolution of brain atrophy measured as brain parenchymal fraction (BPF) and corpus callosum area or -volume

    Measured: 3 years

  5. Development of confirmed sustained disability

    Proportion of patient with confirmed progression in EDSS according to pre-specified criteria

    Measured: 3 years

  6. Mean progression of disability

    The mean change in EDSS over the trial period in the two dosing arms

    Measured: 3 years

  7. Neurodegeneration

    The mean change of s-NFL concentration between the two dosing arms

    Measured: 3 years

  8. Dose persistence

    Time to discontinuation of dosing regimen allocation

    Measured: 3 years

  9. Development of hypogammaglobulinaemia

    The occurrence of hypogammaglobulinaemia in the two dosing arms

    Measured: 3 years

  10. Development of neutropenia

    The occurrence of neutropenia in the two dosing arms

    Measured: 3 years

  11. Development of infections

    The occurrence of infections in the two dosing arms

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Rituximab in people with Multiple Sclerosis, Relapsing-Remitting, run by Karolinska Institutet at 17 sites in Sweden.

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 6 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 19 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in Sweden. 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?

Results are not available in the source record.

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?

No evidence of disease activity (NEDA) (time frame: 3 years). 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 19 Apr 2021.
