Outcome Measures
Primary Outcomes (1)
Peak Unified Dyskinesia Rating Score (UDysRS)
The Unified Dyskinesia Rating Scale (UDysRS) combines patient, caregiver, and treating physician perspectives on both historical (Parts 1 \& 2) and objective (Part 3 \& 4) assessments of dyskinesia and dystonia. The historical portion and the objective ratings are added together to form total score ranging from 0 to 104 with higher scores indicating more severe dyskinesia.
11:00 am
Secondary Outcomes (3)
Peak Unified Dyskinesia Rating Scale - Objective Measures
11:00 am
Presence/Absence of Levodopa-induced Dyskinesia (LID).
Every half hour from 0900 to 1500
Clinical Dyskinesia Rating Scale (Peak)
11:00 am
Study Arms (3)
Statin Before Levodopa
Historical use of a statin BEFORE beginning levodopa
Statin After Levodopa
Historical use of a statin AFTER beginning levodopa
No Statin
No historical use of a statin
Interventions
Intravenous levodopa given 1.0 to 1.5 mg/kg/hr from 0930 - 1130 on a single visit day.

Limitations and Caveats
Type II statins became more popular in use during the course of the study, which led to recruitment difficulties initially and a pivot to allowing most all statin drugs.

- IPD Sharing
- Will share
- Shared Documents
- STUDY PROTOCOL, ICF
- Time Frame
- beginning 5 months and ending 2 years following article publication.
- Access Criteria
- Data will be shared with Investigators whose proposed use of the data has been approved by an independent review committee ("learned intermediary") identified for this purpose.
Individual participant data be available (including data dictionaries). Individual participant data that underlie the results reported the resultant article, after deidentification (text, tables, figures, and appendices). In addition to data, the study protocol and the informed consent form (ICF) will be provided. Data will be available beginning 6 months and ending 2 years following article publication. Data will be shared with Investigators whose proposed use of the data has been approved by an independent review committee ("learned intermediary") identified for this purpose. Data will be released to achieve aims in the approved proposal or for individual participant data meta-analysis. Proposals may be submitted up to 24 months following article publication. After 24 months the data will be available in the investigators' VA'S data repository but without investigator support other than deposited metadata.
