Reporting Groups
  Description
Early Pramipexole Patients initially randomized to pramipexole were up-titrated from 0.375 mg pramipexole daily to 0.75 mg pramipexole daily and then to 1.5 mg pramipexole daily over a 6 week period, and then 1.5 mg pramipexole daily was continued for the remainder of the 15 months of the study.
Delayed Pramipexole Patients initially randomized to placebo, received placebo for 6-9 months, then up-titrated from 0.375 mg pramipexole daily to 1.5 mg pramipexole daily over a 6 week period. These patients were then continued on 1.5 mg pramipexole daily for the remainder of the 15 months of the study.

Measure Type Secondary
Measure Title Modified Minnesota Disorders Interview (MMIDI) for Compulsive Buying at Month 12
Measure Description The MMIDI is a semi-structured interview designed to assess impulse control disorders; compulsive buying is assessed via 4 questions, a participant is considered as being compulsive if answering 'Yes' to Q1a and 'Yes' to 1 or more of Q2a, Q3a and Q4a.
Time Frame Month 12  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The FAS2 was made up of all treated participants with a baseline and on-treatment blinded rater assessment of the UPDRS during Phase 2 of the trial. 140 patients from the FAS2 were excluded due to insufficient MMIDI data.

Early Pramipexole 1.5 milligrams/day pramipexole (for up to 15 months)
