What the trial was testing
The RADIANCE enrolled 1,320 patients with multiple sclerosis. The study was sponsored by Celgene and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
The daily pill reduced MS relapses by 38% compared to the standard weekly injection.
The Lancet. Neurology · 2019 · NCT02047734
These findings — that people taking the daily pill had 38% fewer MS relapses than those on weekly injections — were published in the The Lancet. Neurology and represent the headline result of the study.
Researchers tracked outcomes across 1,320 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with multiple sclerosis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This treatment is FDA-approved and available now for relapsing MS. If you're currently on weekly injections and struggling with side effects or relapses, talk to your neurologist about whether switching to this pill might help. It worked better than the standard injection in this study and was easier for people to stay on.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Motor Imagery and Action Observation for Gait Function in MS
This study will investigate whether mentally simulating walking movements while watching others walk can improve walking performance in individuals with Multiple Sclerosis (MS). Participants will be divided into two groups: one group will watch walking videos and imagine themselves walking, while the other group will watch nature scenes. The study will measure muscle activity and walking patterns to assess the effects. The results may help support the use of mental practice techniques to improve mobility in people with MS.
Evaluate the Safety and Efficacy of Allogeneic Umbilical Cord Mesenchymal Stem Cells in Patients With Multiple Sclerosis
This study is to identify the safety and efficacy of repeat IV(Intravenous) and IT(Intrathecal) administrations of UMSC01 in patients with MS. While anti-inflammatory drugs are routinely used for the treatment of MS by inhibiting immune responses, their effects on axon remyelination or neuroregeneration are limited. The combined systemic delivery of UCMSCs via intravenous injection and local administration of the cells by IT was to have safety and therapeutic efficacy for patients with MS.
