This is a prospective, observational case-control study comparing extracellular vesicles (EVs) from people with Gaucher disease, obligate GBA1 mutation carriers, and age- and gender-matched healthy volunteers. Blood plasma is collected at baseline and again at three months to measure EV quantity, size, and contents. The study aims to explore links between lysosomal dysfunction and EV characteristics and whether EVs could be useful biomarkers.
What it is studying. The study tests whether defects in lysosomal function associated with Gaucher disease or GBA1 carrier status are linked to changes in EV biogenesis, quantity, size, and cargo (including lipids, RNA, proteins and aggregates), and whether those differences relate to neuroinflammation or could serve as biomarkers.
What the researchers hope to learn. Scientific goals: to clarify how lysosomal dysfunction affects EV biogenesis and intercellular communication; to describe differences in EV quantity, size, and molecular cargo (lipids, RNA, proteins and aggregates) between Gaucher patients, carriers, and controls; and to evaluate whether EVs might be useful biomarkers or therapeutic targets for diseases linked to lysosomal dysfunction.
What this study is about
The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.
This is an observational study intended to generate preliminary data to understand how lysosomal dysfunction can affect the biogenesis of extracellular vesicles, its content and function. The primary objective of the proposed project is to decipher how extracellular vesicle (EV) biogenesis and its role in intercellular communication can be impaired as a consequence of defects in lysosomal function. Collectively these defects in EV biogenesis and function can contribute to the neuroinflammation observed in lysosomal storage diseases. Since EVs can cross the blood-brain barrier, their characterization may be valuable in identifying novel biomarkers. In the presence of a GBA1 mutation, the decrease in GCase activity will lower overall lysosome function and increase the secretion of EVs. Further, there will be differences in EV size, its cargo including lipids, RNA and proteins and their aggregates. In comparison to healthy controls, EVs isolated from patients with Gaucher disease (GD) and GBA1 carriers is hypothesized to show significant differences in terms of its characteristics and content, which can contribute to our understanding of the link between lysosomes and neurological disease.

Attend study visits for blood draws at baseline and again about 3 months later so plasma can be used to isolate and study extracellular vesicles (measuring EV quantity, size, and content). No study treatment or intervention is given (observational only). You must have documentation of GD diagnosis or GBA1 mutation status (or sequencing showing no GBA1 mutation for healthy volunteers).
How the study is structured. A prospective observational case-control design with three groups (patients with Gaucher disease, obligate carriers, and matched healthy volunteers). No experimental treatment is given. Participants provide blood plasma at baseline and at three months; isolated EVs are analyzed for quantity, size, and content and compared between groups.
Questions you could ask
These questions are suggestions for a conversation with the study team or your own clinician, not advice.
- This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
- The listed sites are in United States. Is any of them reachable for me, and does the study help with travel?
- Which of the eligibility criteria would need to be checked with tests before I could join?
