Experimental antibody aims to tame rare brain disorder

NCT ID NCT04658199

First seen Jul 17, 2026 · Last updated Jul 17, 2026

Summary

This study tests the long-term safety of an experimental drug called UCB0107 (bepranemab) in people with progressive supranuclear palsy (PSP), a rare brain disorder that affects movement and balance. Participants who completed a prior study receive regular infusions of the drug. The main goal is to see if long-term use is safe and tolerable.
