PREPARED: Comparison of prolonged and immediate release ropinirole in advanced Parkinson's disease. [2011.06]
BACKGROUND: PREPARED was a randomized, parallel-group, double-blind, multicenter study to evaluate the efficacy of adjunctive ropinirole prolonged release (PR) versus immediate release (IR) in patients with advanced Parkinson's disease (PD)... CONCLUSIONS: Adjunctive PR provided a significantly greater improvement in symptom control in terms of the odds of achieving >/= 20% maintained reduction in time spent "off" compared with IR. Interpretation may be confounded by the higher doses of PR versus IR that were achieved, in combination with lower doses of L-dopa by the study end. Despite dosing differences, the PR titration regimen was generally well tolerated, with an AE profile similar to that of IR. Copyright (c) 2011 Movement Disorder Society.

BACKGROUND: Pramipexole and ropinirole have become the first-line treatment for restless legs syndrome. The aim of this study was to perform the first direct comparison between these two molecules in restless legs syndrome... No significant side effects, except for mild morning nausea (2 patients treated with ropinirole, 3 with pramipexole, and 1 with placebo), were reported.
Clinical Trials Related to Requip XL (Ropinirole)
Study to Observe the Effect of Requip PDŽ Once-daily (QD) Versus Twice-daily (BID) [Recruiting]
1. In order to observe the benefit, side effects, and patient preference of Requip PD when
used in QD or BID dosing
2. In order to estimate the conversion rate of dopamine agonists into Requip PD
SWITCH:Restless Legs Patients Switched to Ropinirole From Pramipexole [Recruiting]
The purpose of this study is to determine the equipotent dose of ropinirole and pramipexole
for patients switched from pramipexole to ropinirole in patients with moderate to severe
primary Restless Legs Syndrome (RLS). The rationale behind Switch is that patients with
Restless Legs Syndrome can maintain stable efficacy and tolerability if correctly switched
from one dopamine agonist to an equipotent dose of another.
A Fixed Dose, Dose Response Study for Ropinirole Prolonged Release in Patients With Early Stage Parkinson's Disease [Recruiting]
This study is a fixed dose, dose response study to characterize the dose response for
ropinirole PR in early stage PD patients (Hoehn & Yahr stages I-III). After screening and
baseline assessments, subjects will be randomized to one of six final target treatment
groups (placebo, 2, 4, 8, 12 or 24mg/day ropinirole PR). The study will consist of a
screening period, an up-titration period, a maintenance period, a down titration period and
a follow up period. This study utilizes change from baseline in the UPDRS motor score as the
primary endpoint, in line with that used in the ropinirole PR monotherapy pivotal study
(SK&F101468/168). Clinical review of the primary and secondary endpoints will be performed
in order to establish the lowest maximally effective therapeutic dose.
A Phase III, Randomised, Double-blind, Placebo-controlled, Parallel Group Study of Six Months Treatment With Ropinirole PR as Adjunctive Therapy in Patients With Parkinson's Disease Who Are Not Optimally Controlled on L-Dopa [Recruiting]
This is a phase III, multicenter, randomized, double-blind, parallel group,
placebo-controlled study to compare the efficacy of 6-months therapy of ropinirole Prolonged
Release (PR) with that of placebo as adjunctive therapy to L-dopa in Parkinson's disease
patients not optimally controlled on L-dopa. This study will be conducted in China. Subjects
will have total 14 visits over the 26 week duration of the study.
Following screening, eligible subjects will receive study medication during the fourteen day
placebo run-in period which they will be instructed to take in addition to their background
L-dopa. If subjects are still eligible at the end of the placebo run-in period they will be
randomized (1: 1) to receive once daily doses of ropinirole PR or identical appearing placebo
tablets. Dosing will start at 2 mg ropinirole PR, or placebo equivalent. During the 24 week
treatment phase, the subjects dose will be adjusted according to the recommended schedule to
achieve symptomatic control. All subjects must be titrated to a minimum dose of 6 mg/day. If
sufficient symptomatic control is not achieved or maintained at a dose of 6mg/day of
ropinirole PR, the daily dose should be increased by 2mg at weekly or longer intervals up to
a dose of 8mg/day. If sufficient symptomatic control is still not achieved or maintained at a
dose of 8mg/day of ropinirole PR, the daily dose should be increased by 4mg at two weekly or
longer intervals. Further dose titration should not be conducted within the final 8 weeks of
the treatment phase. The maximum recommended daily dose is 24mg.
The planned reduction in L-dopa dose will begin once subjects are titrated to Dose Level 4
or Dose Level 5 of study medication. For each increase in study medication, there will be a
corresponding decrease in L-dopa. If loss of symptom control occurs with the reduction in
the background L-dopa dose, the dose of study medication should be increased to the next
higher dose level with no adjustment in the dose of L-dopa. If loss of symptom control
persists, subjects should be titrated up an additional dose level. Subjects who do not
experience an improvement in symptoms following upward titration by 2 dose levels of study
medication, should be "rescued" with L-dopa.
Subjects will be dispensed down-titration medication at the study completion/early
withdrawal visit if the patient did not enter extension study and should be scheduled to
return for a follow up visit 4 to 14 days after the last dose of study medication. The
extension study aim to evaluate the safety profile of ReQuip PR during long-term treatment
in subjects with advanced parkinson's disease.
A Fixed Dose Study of Ropinirole Prolonged Release as Adjunctive Treatment in Patients With Advanced Parkinson's Disease [Recruiting]
This is a double blind, fixed dose, parallel group study to characterize the dose response
of ropinirole PR as adjunctive therapy to L-dopa in patients with late stage Parkinson's
disease. The primary endpoint of this study, mean change from baseline in total awake time
spent "off' is the same endpoint as used in the ropinirole PR pivotal study for advanced
Parkinson's disease patients. This study includes a wide range of ropinirole doses (4-24mg)
with the 8mg, 12mg, and 16mg per day doses powered to detect a 1. 7 hour difference in total
awake time spent "off" compared with placebo. The dose of Ldopa will remain stable through
the study, unless the subject experiences tolerability issues that require an L-dopa dose
reduction. Up to three L-dopa dose reductions are allowed, making a total reduction of up to
approximately 30%. Keeping the L-dopa dose constant where possible is important to avoid
confounding the efficacy data. Clinical review of the primary and secondary endpoints will
be performed in order to establish the lowest maximally effective therapeutic dose.
