Official title

Cutaneous Phosphorylated Alpha-Synuclein for Detection of Prodromal Synucleinopathies

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In collaboration with approximately 8 centers that specialize in iRBD we will recruit a total of 80 individuals for the study. All subjects will be enrolled into a 2-year longitudinal study where skin biopsies will be performed at 3 sites on each patient at 12-month intervals (baseline, year 1, year 2). Plasma blood collection will be performed at 12-month intervals (baseline, year 1, year 2). Detailed quantified examination, cognitive evaluation, medical history, and questionnaires will be performed at each visit. Additional biomarker, imaging and clinical information (if available) will be obtained for the purpose of determining phenoconversion to clinically apparent synucleinopathy. Subjects enrolled in the study will have baseline evaluations and follow up visits at 12 and 24 months to define any changes to clinical diagnosis (clinical phenoconversion). Skin biopsies will be repeated at the 12- and 24-month follow up visits to determine the rate of P-SYN accumulation over time and the rates of nerve fiber degeneration within punch skin biopsies.
