An IV Drug Cut Multiple Sclerosis Relapses in Half Versus a Pill

Researchers compared ublituximab (a drug given through an IV) to teriflunomide (a pill) in people with relapsing multiple sclerosis. Those who got ublituximab had 59% fewer relapses and far fewer new brain lesions over nearly two years.

What the trial was testing

The ULTIMATE 1 enrolled 549 patients with multiple sclerosis. The study was sponsored by TG Therapeutics, Inc. 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 taking ublituximab had 59% fewer relapses than those on teriflunomide.

The New England journal of medicine · 2022 · NCT03277261

These findings — that ublituximab cut relapse rates by more than half compared to teriflunomide — were published in the The New England journal of medicine and represent the headline result of the study.

Researchers tracked outcomes across 549 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

Ublituximab was FDA-approved in 2022 based on these results and is now available as Briumvi. About half of patients had mild reactions during the infusion. Talk to your neurologist about whether this treatment is right for you.

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.
