What the trial was testing
The ASCLEPIOS I enrolled 927 patients with multiple sclerosis. The study was sponsored by Novartis 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
People on ofatumumab had 49% fewer relapses per year and 97% fewer new active brain lesions compared to those taking teriflunomide.

These findings — that ofatumumab reduced the annualized relapse rate by nearly half compared to the standard daily oral treatment — were published in the New England Journal of Medicine and represent the headline result of the study.
Researchers tracked outcomes across 927 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
Ofatumumab (Kesimpta) is FDA-approved for relapsing MS and can be self-injected at home once a month after an initial loading period. ASCLEPIOS I and II together enrolled nearly 1,900 people — one of the larger relapsing MS trial programs in recent years. If you have relapsing MS and want a high-efficacy, home-based option, ask your neurologist whether ofatumumab fits your situation.
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.

Clinical and Urodynamic Assessment of Bladder Sensation in Multiple Sclerosis
The aim of the study is to assess the association between bladder sensations progression during bladder filling and severity of Overactive bladder (OAB) in patients with multiple sclerosis.
Cohort Study on Neuroimmune Diseases in the Reproductive Age
Neuroimmune diseases are more prevalent among women of reproductive age. Studies have shown that neuroimmune diseases may impact fertility. Therefore, effective management of neuroimmune diseases during pregnancy is particularly important. This study included a follow-up period of up to five years in patients with pregnancy-associated neuroimmune disorders. Data collected included relapse frequency, symptomatology, imaging findings, treatment regimens, peripheral blood profiles, EDSS scores, and MRI results. In addition, maternal drug concentrations, postpartum relapse rates, and neonatal development were monitored after delivery. Following the successful completion of the five-year follow-up, the research team plans to continue the prospective epidemiological study with ten-year follow-up phases. The aim of this study is to generate detailed clinical data on pregnancy-associated autoimmune diseases and to equip clinicians with evidence-based strategies for optimizing disease management during the reproductive age.
