Trial overview

Official title: A 4-Week, Randomized, Double-Blind, Cohort Study to Evaluate the Safety and Tolerability of Converting from Ropinirole Immediate Release (IR) to Ropinirole Controlled Release for RLS (CR-RLS) Formulation (Formerly Ropinirole Extended Release [XR]) in Patients with Restless Legs Syndrome (RLS)
Trial description: This is a multi-center, Phase III study to evaluate the safety and tolerability of proposed dose conversion recommendations for RLS subjects converting from ropinirole immediate release to ropinirole controlled-release for RLS.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Not applicable
Allocation:
Randomized
Primary outcomes:

Number of adverse events (AEs) post-conversion from ropinirole IR to ropinirole CR over period

Timeframe: Up to 5 weeks

Secondary outcomes:

Number of participants discontinuing the drug due to AEs post conversion from ropinirole IR to ropinirole CR-RLS

Timeframe: Up to 5 weeks

Number of participants with SAEs and severity of AEs

Timeframe: Up to 5 weeks

Number of participants with positive scores (improved) on clinical global impression improvement scale (CGI-I) pre-conversion and one week post-conversion

Timeframe: Up to 4 weeks

Change from pre-conversion in international RLS (IRLS) rating scale total score to one week post-conversion

Timeframe: Up to 5 weeks

Number of participants with pre-and one week post-conversion values of vital signs of potential clinical concern (PCC)

Timeframe: Up to 5 weeks

Change from pre-conversion in systolic and diastolic orthostatic SBP and DBP to one week post-conversion

Timeframe: Up to 5 weeks

Change from pre-conversion in pulse rate to one week post-conversion

Timeframe: Up to 5 weeks
