NAD supplement trial for atypical parkinsonism
Treatments studied
Part of Brain & nervous system, Eyes & vision clinical trials.
This trial tests whether a supplement called nicotinamide riboside (NR) can help people with rare forms of parkinsonism (PSP, MSA, or CBS). It is a double-blind study, meaning neither you nor the doctors will know if you are getting the real supplement or a placebo.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 30 and 85 years old.
- You have been diagnosed with PSP, MSA, or CBS by a doctor.
- You have had a brain scan (DaTSCAN or FDOPA-PET) that fits your diagnosis, and if it was negative, it must be less than two years old.
- You can walk at least 5 steps with a walker or with help from one person (you don't need to walk alone).
- Your memory and thinking are good enough to participate (score of 20 or higher on a mental status test).
- You haven't taken nicotinamide riboside (NR) supplements or any experimental drugs in the last 90 days.

This study looks at genetic factors in people with PSP, CBS, MSA, or similar brain conditions, and also in their family members. It involves genetic testing to learn more about these diseases and may help find new treatments.
This study tests a remote monitoring system to track symptoms of progressive supranuclear palsy (PSP) and similar movement disorders. It may tell you how your condition changes over time without needing frequent clinic visits.
This Phase 1 study checks how safe a drug called ION464 is, how the body handles it, and how much of the drug reaches the bloodstream in adults with multiple system atrophy (MSA). It may help researchers find a dosing approach for future treatments for MSA.
This trial tests if a vitamin B3-like supplement, nicotinamide riboside, can help people with early to mid-stage Huntington's disease. You will be randomly assigned to take the supplement or a placebo to see if it slows the disease.
This study tests whether a supplement called NAD (a natural substance that helps cells produce energy) can improve symptoms in people with Parkinson's disease. You would take the supplement daily for several weeks, and researchers will check your movement, thinking, and overall well-being.
This trial tests a new medicine called NIO752 for people with progressive supranuclear palsy (PSP), a condition that affects movement, balance, and thinking. The goal is to see if it can help slow the disease's progression.
