Discontinuing Disease-modifying Therapies in Stable Relapsing - Onset Multiple Sclerosis (DOT-MS). (DOT-MS)

October 13, 2020 updated by: Eline Coerver, Amsterdam UMC, location VUmc

The Safety and Cost-effectiveness of Discontinuing Disease-modifying Therapies in Stable Relapsing - Onset Multiple Sclerosis (DOT-MS): a Randomized Rater-blinded Multicenter Trial.

The aim of this study is to identify whether it is possible to safely discontinue treatment in relapsing-onset MS patients who have shown no evidence of active inflammation in the years prior to inclusion clinically and/or radiologically. The secondary objectives address the questions whether the discontinuation of first-line treatment has an effect on disability progression and whether the discontinuation of first-line treatment improves the quality of life for the patient. Furthermore, blood collections will be included to assess whether it is possible to retrospectively predict possible return of inflammatory activity with biomarkers such as neurofilament light (NFL) or patient characteristics such as disease activity prior to disease modifying therapy (DMT). In case of emerging disease activity after the cessation of therapy we will assess if reinitiation will lead to NEDA again, and if there are long-term consequences. If possible, post-hoc analysis are performed for the different types of treatment compounds.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Minimum age of 18 years
  • Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (PHI) in accordance with national and local privacy regulations.
  • Definite diagnosis of relapsing-onset MS according to the revised McDonald 2017 criteria
  • Treatment with one of the first-line DMTs: any of the interferons, glatiramer acetate, dimethylfumarate, teriflunomide
  • Complete absence of inflammatory activity (no objectively defined and confirmed relapses, no significant number (2 or more) of new-T2 lesions and no contrast-enhancing lesions) for 5 consecutive years under first-line treatment

Exclusion Criteria:

  • A switch between first-line disease modifying therapy over two years prior to inclusion, in case the switch has been due to in effectivity of the first DMT.
  • Women who want to discontinue medication because of a pregnancy wish and women who are pregnant or expect to become pregnant during the study period
  • Patients that have previously used interferon-beta and have been tested positive for neutralizing antibodies (NAbs).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical relapses
Time Frame: 2 years
New clinically confirmed relapses (defined according to the definition most often used in MS phase-III trials: the onset of new or recurrent symptoms that last > 24 hours, that are accompanied by new objective abnormalities on a neurological examination and that are not explained by non-MS processes such as fever, infection, severe stress or drug toxicity).
2 years
New lesions on MRI-brain
Time Frame: 2 years
New inflammatory disease activity on MRI (defined as 3 or more lesions on T2-weighted vimages or 2 or more gadolinium enhancing lesions on T1-weighted post-contrast MRI).
