NCT ID NCT06235775
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at the long-term safety of a daily injection called GV1001 in people with progressive supranuclear palsy (PSP), a rare brain disease that affects movement and balance. It included 67 patients who had already completed a previous GV1001 study. Researchers monitored side effects and lab results over 12 months to see if the drug remains safe for extended use.
