Summary

This Phase 2 trial tests whether the drug LM11A-31 can slow the progression of Progressive Supranuclear Palsy (PSP), a rare brain disorder that affects movement and balance. About 147 people with early-stage PSP will receive either the drug or a placebo twice daily for several months. Researchers will measure changes in disease severity using a specialized rating scale.
