A Phase 2 Study and Open-Label Extension of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease

Study on NEU-411 for early Parkinson's with specific diagnostic markers.

Recruiting
40-80 years
All
Phase 2

Early Parkinson's Disease is when the brain slowly stops controlling movement well. This study is looking at a medicine called NEU-411 to see if it helps people with a special type of Parkinson's where a gene called LRRK2 is too active. A DNA test will help find people with this special type. The study will see if NEU-411 is safe and works well.

People who join will either take NEU-411 or a placebo (a pill that does nothing) every day for 52 weeks. Around 150 people will join, and they will be randomly picked to get the real medicine or the placebo. A follow-up visit will happen two weeks after the last dose.

  • Participants must be aged 50-80 and have early Parkinson's.
  • They need a genetic test showing LRRK2 activity.
  • The study lasts about a year with regular medicine intake.

People with other serious health issues or different types of Parkinson's cannot join. Full details are in the study protocol.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
