Participant Stories

“I participate because it is the right thing to do, for myself, for my children, and for the millions of people who have Parkinson’s disease.  Without participation there will be no cure.” –Mike, Diagnosed 7 years

Browse Clinical Trials by Type

Every clinical study has different objectives. Some trials test new treatments while others seek to answer questions about the disease through observation.

In an interventional trial, the investigators give the participants a particular investigational drug or other intervention, which may include a gene transfer, vaccine, device, or procedure, such as surgery. The intervention may or may not be assigned randomly, and sometimes treated individuals might be compared with those who receive no treatment. The researchers then measure how the health of the participant changes. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective.

In an observational study, there is no intervention. Studies that examine brain or motor activity, or genetic or environmental factors, may fall into this category. These studies are often done to better understand PD, which is an important part of developing new treatments, therapies, or preventions. Participants in observational studies do not receive investigational treatment for their disease.
