Ofatumumab Shows Long-Term Improvements in Multiple Sclerosis Disease Activity

After 4 years of treatment with ofatumumab, 78.8% of patients with relapsing forms of multiple sclerosis who continuously received ofatumumab achieved NEDA-3 compared to 51.8% of those who switched from teriflunomide to ofatumumab.

Novartis announced new data from the phase 3 ASCLEPIOS 1/2 and the ALITHIOS open-label extension showing continuous treatment with ofatumumab (Kesimpta) for relapsing forms of multiple sclerosis (RMS) significantly increased the odds of achieving no evidence of disease activity (NEDA-3) compared to switching from teriflunomide. The data were presented at the European Academy of Neurology Annual Meeting held in Vienna, Austria.1

“Early initiation of high-efficacy therapies for the treatment of relapsing multiple sclerosis has been shown to improve long-term outcomes versus escalating from lower efficacy therapies,” Ludwig Kappos from University Hospital Basel, said in a statement. “NEDA-3 is an important endpoint for physicians to consider when deciding to initiate high efficacy therapy, with this latest data from ALITHIOS we can clearly see the benefit of starting [ofatumumab] early versus switching to it later from teriflunomide.”1

The data show that after 4 years of treatment, 78.8% of those who continuously received ofatumumab achieved NEDA-3, which was defined as having no MS relapses, no disability worsening, and no MRI activity compared to 51.8% of those who switched from teriflunomide to ofatumumab in the extension phase.1

The results build on previously presented efficacy data from both studies, showing sustained differences in cumulative responses, MRI lesion activity, and the risk of disability worsening between patients continuously treated with ofatumumab versus those who were switched at a later date.1

Ofatumumab is a targeted treatment that is precisely dosed to deliver B-cell therapy and provides the flexibility of self-administration for adults with RMS. The drug is designed to be delivered subcutaneously via a once-a-month injection.

Ofatumumab is currently approved for treatment of RMS in the United States, European Union, United Kingdom, Canada, China, Switzerland, Singapore, Australia, Japan, Argentina, United Arab Emirates, Albania, and India.

According to the Mayo Clinic, MS is a disabling disease of the central nervous system, including the brain and the spinal cord. The cause of MS is unknown, and it is considered an autoimmune disease in which the body’s immune system attacks its own tissues. The immune system malfunction destroys the fatty substances that coats protective nerve fibers.2

Individuals with MS can experience muscle stiffness, muscle spasms, paralysis, problems with bladder, bowel, or sexual functions, mental changes, depression, and epilepsy.2
