A 6 Week Trial to Study the Efficacy and Safety of a Starting Dose 0.25 mg Pramipexole (Mirapex) in Patients With RLS
This trial is a 6-week, double-blind, randomized, active and placebo-controlled parallel-group study with a primary objective of comparison of starting doses of pramipexole fixed-dose (0.25 mg daily) and pramipexole titrated-dose (0.125 mg qd for 1 week, then 0.25 mg qd for the remaining 5 weeks) with placebo to evaluate efficacy and safety in treating RLS symptoms in patients diagnosed with idiopathic RLS.
The secondary objectives of this study will be to assess the onset of action of symptomatic relief of RLS for pramipexole with daily assessment of PGI and modified IRLS during two intervals of the first 2 weeks (Days 2, 3 and 4 and Days 9, 10, and 11) and assessment of IRLS, PGI and CGI-I at Weeks 1, 2, 4 and 6 (CGI-I additionally on Day 3).
