First seen Nov 01, 2025 · Last updated May 13, 2026 · Updated 26 times

Summary

This study looks at how many people with multiple sclerosis (MS) develop antibodies against the drug natalizumab when they receive it as an injection under the skin. Researchers will track about 400 patients from European MS registries, including both those new to the drug and those switching from an IV form. The goal is to better understand immune reactions and safety, not to test a new treatment.
