CureDRPLA Global Patient Registry

Study Overview
=================
Brief Summary
-----------------
The objective of the CureDRPLA Global Patient Registry is to establish a longitudinal database of patient-reported data on individuals affected with Dentatorubral-pallidoluysian atrophy (DRPLA) from anywhere in the world. The CureDRPLA Global Patient Registry will address patient needs by: Expanding patient engagement by documenting quality of life outcomes. Providing anonymized data to the DRPLA research community on patient experience with the disease and priorities for treatment. Connecting DRPLA patients with opportunities to participate in clinical research.

Detailed Description
-----------------
The CureDRPLA Global Patient Registry aims to collect data from Dentatorubral-pallidoluysian atrophy (DRPLA) patients worldwide to identify a well-characterized cohort for participation in retrospective and prospective research. Participants will be required to read and sign an IRB-approved informed consent document prior to accessing questionnaires within the Registry. The Registry is solely for patients diagnosed with DRPLA. After informed consent is given, and assent for those age 12 to the age of consent, participants will be asked to complete a series of questionnaires to include information on demographics, specifics of diagnosis, medical history, research, functional mobility, quality of life, and health economics. Participants will be asked to indicate if they are interested in being contacted by the Registry Coordinator for potential participation in future clinical trials and/or studies. Participants will have the option to withdraw from the Registry at any time, and upon withdrawal, they will no longer be contacted from the Registry for any reason. Data that they have entered will remain part of the Registry, but their identification will not be released for any reason. Active participants in the Registry will receive yearly email reminders to update their questionnaire data to reflect the current status of disease progression. The Registry is available in English, French, Italian, Japanese, Korean, and Portuguese to encourage DRPLA patients worldwide to register. Participation is completed online, please visit our website for more information https://curedrpla.org/en/global-patient-registry/ The REDCap Cloud platform will serve as the Registry Data Coordinating Center and will manage data entered into a web based electronic data capture (EDC) system that is 21 CFR Part 11 validated, ISO 27001 certified, HIPPA, CDISC, and GDPR compliant.
