An OBSERVATIONAL STUDY is a type of clinical study in which participants are identified as belonging to study groups and are assessed for biomedical or health outcomes. Participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions/treatments.
Assessment may be based on data collected from participants at a point in time or over a period of time.
|INT Phase 1||40||26|
|INT Phase 2||61||30|
|INT Phase 3||17||9|
|INT Phase 4||14||6|
|INT No Phase||170||72|
Studies with no phase specified may include evaluations of interventions such as exercise, physical therapy, speech therapy, dietary supplements and more.

Phase 3 evaluates therapy safety and efficacy with 100's or thousands of participants.
An INTERVENTIONAL STUDY (or Clinical Trial) is a clinical study in which participants are assigned an intervention such as a medication, device, or procedure, so that researchers can evaluate its effects on biomedical or health-related outcomes. Participants may receive diagnostic, therapeutic, or other types of interventions. Randomized, placebo-controlled clinical trials are the gold standard for assessing the safety and effectiveness of a therapy.

This page provides access to information about currently recruiting interventional and observational Parkinson's disease studies taking place around the world. It is intended to help patients and controls find trials of interest to them that they may qualify to participate in. Unless otherwise noted, recruiting trial information is provided through ClinicalTrials.gov. (See ClinicalTrials.gov overview.) Further information about any trial you may be interested in can be obtained by contacting the trial coordinator listed in the trial description.
Phase 4 involves further study of therapies already FDA-approved.
