An OBSERVATIONAL STUDY collects and analyzes data from participants in order to better understand a disease and to further the development of biomarkers and improved treatments.  For example, participants may be asked to complete questionnaires, provide blood or CSF samples, undergo scans, or use a wearable device. Data may be collected at a point in time or longitudinally.

The Charter for Clinical Trials in Parkinson's, published by The Cure Parkinson's Trust & Parkinson's Movement, provides helpful guidelines for potential trial participants.

Phase 1 evaluates therapy safety with small # participants ( <100).

Phase 2 evaluates therapy safety and efficacy with up to several hundred participants.

Phase 4 involves further study of therapies already FDA-approved.

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.     Clinical trial phase definitions
