Summary
This trial will test the safety & effectiveness of a potential new treatment for Progressive Supranuclear Palsy (PSP). It will be done in two phases: a randomized blind trial & an optional open-label extension.
Who is the study for?
This trial is for people aged 40-80 with Progressive Supranuclear Palsy (PSP) who've had symptoms for less than 5 years. They must be able to walk with little help, score at least 24 on a mental state exam, and not live in skilled nursing or dementia care facilities.
What is being tested?
The ORION Trial tests the effectiveness and safety of AMX0035 against a placebo in PSP patients. It starts with a phase where participants are randomly assigned to get either AMX0035 or placebo without knowing which one they receive.
What are the potential side effects?
While specific side effects of AMX0035 aren't listed here, common ones may include digestive issues, headaches, fatigue, and potential allergic reactions. The exact side effects will be monitored throughout the trial.
