Taking Part

Can I join?

There are several criteria to meet if you want to join the Orchestra Study. The most important ones are*:

  • Aged 40–75 years
  • Have been diagnosed with Parkinson’s disease in the past 2 years
  • Experience slowness of movement and at least one of the following:
    • Muscle stiffness/rigidity
    • Tremor/shaking
  • Have not taken any medications to treat Parkinson’s disease motor symptoms (symptoms related to movement) and are not expected to need any such medications in the next 6 months.

*There are additional criteria to enroll in the study—the study team will assess these and discuss them with you.

The study is investigating the effect of the study drug on the progression of Parkinson’s disease and associated symptoms over a longer period of time. Therefore, the Orchestra Study can only recruit individuals with mild Parkinson’s disease symptoms.

If you meet these criteria, take the pre-screener. If you pre-qualify, you will be referred to your nearest study site. At the study center, you will discuss the study in detail and find out whether you can take part.


What is informed consent?

Prior to any study related tests and procedures, you must agree to and sign an Informed Consent Form, or ICF.

This document explains the study in detail, including potential risks and benefits, as well as your rights and responsibilities.

Is the Orchestra Study right for me?

Taking part in clinical research requires careful thought. Before you decide whether to participate, make sure that you understand any potential risks involved.

There is no guarantee that you will benefit from taking part in this study. And remember, clinical studies are completely voluntary. You are free to leave at any time and for any reason, with no penalty to you.

Talking to your study team can help you decide whether you would like to participate in the Orchestra Study. They will explain the study to you and give you more details, including written information like the Informed Consent Form.


Study physicians and specialists will closely monitor participants’ condition and well-being throughout the study.
