Transcutaneous Submandibular Gland Biopsy: Feasibility of Repeat Biopsy as a Progression Marker for Parkinson's Disease
Tab Title Description
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
The purpose of this study is to perform biopsies of one of the glands that make saliva. The biopsied tissue will then be analyzed to see if it has changes that occur in Parkinson's disease. This study will determine whether it is possible to do a second biopsy a few years after a previous biopsy and determine whether there are changes in the biopsy that would allow for analysis of disease progression.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
