Brief summary

This is a multicenter, placebo controlled, parallel group, double-blind, randomized comparison study to evaluate the efficacy and safety of ropinirole IR tablets orally administered for 12 weeks in patients with symptomatic restless legs syndrome associated with Chronic kidney disease (CKD) managed with haemodialysis (including haemofiltration and haemodiafiltration) (hereinafter referred to as uRLS), to evaluate the efficacy and safety of long-term administration of ropinirole IR tablets, and assess the effect on the steady state pharmacokinetics in the long-term administration period of ropinirole IR tablets.

Interventions

DRUGRopinirole immediate release (IR)

Subjects completing the screening period will be randomized (1:1) to receive the IR or placebo for 12 weeks. The treatment will be started at the initial dose of 0.25 mg/day within 1 to 3 hours before bedtime. The maximum available dose is 3 mg/day. For all subjects completing short-term period and entering the long-term treatment period, the open-label treatment will be started from IR 0.25 mg/ day regardless of dose levels during short-term period. The dose will be upward titrated from 0.25 mg/day to 0.5 mg/day and after that in increments of 0.5 mg/day until sufficient efficacy is obtained (targeting much improved or very much improved in the CGI-I) without safety/tolerability problem.

DRUGPlacebo

Subjects completing the screening period will be randomized (1:1) to receive the IR or placebo for 12 weeks. The treatment will be started at the initial dose of 0.25 mg/day within 1 to 3 hours before bedtime.

Recruitment details

This study was prematurely terminated after 5 months had passed since its initiation, because GlaxoSmithKline (GSK) concluded that it was impossible to recruit sufficient participants within a reasonable timeframe. In this study, no participants had completed. The maximum duration was 24 weeks plus follow-up (up to Week 64).

Participants by arm

ArmCount
Ropinirole IR-Ropinirole IR
Participants received immediate-release (IR) tablets of ropinirole once daily for 12 weeks in the double-blind treatment period. The dose of investigational product (IP) was upward titrated from 0.25 milligram (mg)/day to 0.5 mg/day at an interval of at least 1 week, followed by upward titration in increments of 0.5 mg/day at intervals of at least 1 week until sufficient efficacy was obtained (targeting much improved or very much improved in the investigator/subinvestigator-assessed Clinical Global Impression - Improvement \[CGI-I\]) without a safety/tolerability problem, although the dose did not exceed 3 mg/day. All participants completing the double-blind treatment period were eligible to continue in the open-label long-term treatment period. In the open-label period, participants were to receive ropinirole IR tablets once daily for 52 weeks with a similar upward titration method as in the double-blind treatment period.

Placebo-Ropinirole IR
Participants received matching placebo to ropinirole IR in the double-blind treatment period. All participants completing the double-blind treatment period were eligible to continue in the open-label long-term treatment period. In the open-label period, participants received ropinirole IR tablets in the same way as in the ropinirole IR-ropinirole IR group.

Johns Hopkins RLSQOL Questionnaire Overall Life Impact Score for Participants Who Withdrew in the Long-term Treatment Period (LONG WD)

The RLSQOL questionnaire is a participant-rated questionnaire designed to assess the impact of RLS on the lives of participants. It consists of 18 items, 10 of which contribute to a single summary score (overall life impact). The response for each item is coded from 1 to 5, with 1 representing the best quality of life and 5 representing the worst quality of life. The lowest possible overall life impact score is 0, and the highest possible overall life impact score is 100. The score of 100 represents the best possible quality of life.

The Pittsburgh Sleep Quality Index (PSQI) Total Score at Week 0 and Week 12

The PSQI consists of the following 7 domains: sleep quality, duration getting to sleep, sleep duration, sleep adequacy, sleep disturbance, use of sleeping pill, and somnolence. These domains are numerically scored from 0 to 3, with 0 representing the least severe response and 3 representing the most severe response. The PSQI total score is calculated by summing the individual domain scores. The highest possible score is 21, which represents the most disturbances in sleep quality; the lowest possible score is 0, which represents an absence of disturbances in sleep quality.

Time frame: Week 0 and Week 12

Population: FAS. Participants withdrawn from the study before Week 12 were not included in the analysis.

The PSQI Total Score for Participants Who Withdrew fn the Long-term Treatment Period (LONG WD)

The PSQI consists of the following 7 domains: sleep quality, duration getting to sleep, sleep duration, sleep adequacy, sleep disturbance, use of sleeping pill, and somnolence. These domains are numerically scored from 0 to 3, with 0 representing the least severe response and 3 representing the most severe response. The PSQI total score is calculated by summing the individual domain scores. The highest possible score is 21, which represents the most disturbances in sleep quality; the lowest possible score is 0, which represents an absence of disturbances in sleep quality.

Time frame: LONG WD (up to Week 64)

Population: FAS. Participants with no measurement data in the long-term treatment period because of their premature withdrawal without receiving the IP in that period were not included in the analysis.

The PSQI Total Score for Participants Who Withdrew From the Double-Blind Treatment Period (DBT WD)

The PSQI consists of the following 7 domains: sleep quality, duration getting to sleep, sleep duration, sleep adequacy, sleep disturbance, use of sleeping pill, and somnolence. These domains are numerically scored from 0 to 3, with 0 representing the least severe response and 3 representing the most severe response. The PSQI total score is calculated by summing the individual domain scores. The highest possible score is 21, which represents the most disturbances in sleep quality; the lowest possible score is 0, which represents an absence of disturbances in sleep quality.

Time frame: DBT WD (up to Week 12)

Population: FAS. Participants with missing DBT WD data were not included in this analysis.
