New drug hope for kids with MS: ublituximab trial launches
NCT ID NCT07220252
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 4 times
Summary
This study tests the drug ublituximab in children aged 10 to 18 with relapsing multiple sclerosis (MS). It compares ublituximab to another drug, fingolimod, to see which better controls relapses. The trial involves 240 participants and will also monitor long-term safety and effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ublituximab (a drug given by IV infusion)
- What this could lead to
- If successful, this could provide a new treatment option for children with relapsing multiple sclerosis to reduce relapses.
- What could go wrong
- This is an early-to-mid stage trial (Phase 2/3) with 240 participants, so results may not confirm long-term benefit or safety. Risks include infusion reactions and infections.
