Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This completed Phase 3 trial tested the oral drug dimethyl fumarate (Tecfidera) against an injected interferon in 156 children aged 10 to 17 with relapsing-remitting multiple sclerosis. The main goal was to see if the drug could prevent new brain lesions and control the disease safely. The study also looked at long-term safety in an optional extension phase.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dimethyl fumarate (Tecfidera)
What this could lead to
If successful, this could provide a safe and effective oral treatment option for children with relapsing-remitting multiple sclerosis, reducing brain lesions and slowing disability.
What could go wrong
This is a completed Phase 3 trial, but results may not apply to all children. Side effects like flushing and stomach issues are common with dimethyl fumarate, and long-term safety data are still limited.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: * Males and females aged from 10 to less than 18 years old at the time of informed consent or assent. * Must have a body weight of ≥30 kg. * Must have a diagnosis of RRMS (consensus definition for pediatric RRMS \[Krupp 2013\]). * Must be ambulatory with a baseline EDSS score between 0 and 5.5, inclusive. * Must have experienced at least 1 of the following 3 conditions: a) at least 1 relapse within the last 12 months prior to Day 1 with a prior brain MRI demonstrating lesions consistent with MS; b) at least 2 relapses within the last 24 months prior to Day 1, with a prior brain MRI demonstrating lesions consistent with MS; c) evidence of Gd-enhancing lesions of the brain on an MRI performed within the 6 weeks prior to Day 1. * Must be neurologically stable, with no evidence of relapse within 50 days prior to Day 1 and no evidence of corticosteroid treatment within 30 days prior to Day 1. * Participants of childbearing potential who are sexually active must be willing to practice effective contraception during the study and be willing and able to continue contraception for at least 30 days after their final dose of study treatment. Key Exclusion Criteria: * Primary progressive, secondary progressive, or progressive relapsing MS (as defined by \[Lublin and Reingold 1996\]). These conditions require the presence of continuous clinical disease worsening over a period of at least 3 months. Participants with these conditions may also have superimposed relapses but are distinguished from relapsing-remitting participants by the lack of clinically stable periods or clinical improvement. * Disorders mimicking MS, such as other demyelinating disorders (e.g., acute disseminated encephalomyelitis), systemic autoimmune disorders (e.g., Sjögren disease, lupus erythematosus), metabolic disorders (e.g., dystrophies), and infectious disorders. * History of premalignant or malignant disease. Participants with basal cell carcinoma that has been completely excised prior to screening will remain eligible. * History of severe allergic or anaphylactic reactions, or known drug hypersensitivity to DMF, fumaric acid esters, or interferon beta-1a (IFN Beta-1a). * History of abnormal laboratory results indicative of any significant endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, renal, and/or any other major disease that would preclude participation in a clinical study. * History of clinically significant cardiovascular, pulmonary, GI, dermatologic, growth, developmental, psychiatric (including depression), neurologic (other than MS), and/or other major disease that would preclude participation in a clinical study. * History of human immunodeficiency virus. * An MS relapse that has occurred within 50 days prior to Day 1 AND/OR the participant has not stabilized from a previous relapse prior to Day 1. * Other unspecified reasons that, in the opinion of the Investigator or Biogen Idec, make the participant unsuitable for enrollment. NOTE: Other protocol-defined inclusion/exclusion criteria may apply
