NCT ID NCT06220669

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial tests an experimental drug called LY3541860 against a placebo in 63 adults with relapsing multiple sclerosis. The goal is to see if the drug can slow the appearance of new brain lesions seen on MRI scans. The study lasts about 9 months, with an additional 6 months of follow-up.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
LY3541860 (an experimental drug given by IV)
What this could lead to
If it works, this could point toward a new treatment that reduces brain lesion activity in people with relapsing multiple sclerosis.
What could go wrong
This is an early Phase 2 trial with only 63 participants, so results may not apply to everyone. The drug may not slow lesions better than placebo, and side effects are still being studied.
