A Fixed Dose, Dose Response Study for Ropinirole Prolonged Release in Patients With Early Stage Parkinson's Disease (TANDEM-662)
June 18, 2018 updated by: GlaxoSmithKline
A Fixed Dose, Dose Response Study for Ropinirole Prolonged Release (PR) in Patients With Early Stage Parkinson's Disease
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.

Exclusion Criteria:
- Subjects with Parkinson's disease in whom dopaminergic therapy is not warranted at the time of screening.
- Subjects with severe, clinically significant condition(s) other than Parkinson's disease which, in the opinion of the investigator, render the subject unsuitable for the study (e.g., psychiatric, haematological, renal, hepatic, endocrinology, neurological [other than Parkinson's disease], cardiovascular, or active malignancy [other than basal cell carcinoma]).
- Subjects with crippling degenerative arthritis or other physical or mental conditions precluding accurate assessment of efficacy or safety.

- Subjects on chronic therapy with any of these agents may be enrolled but doses must have remained stable from 7 days prior to baseline (randomization) through the end of the treatment period. Smokers should maintain normal smoking habit.
- Women who are pregnant or breast-feeding.
- Use of an investigational drug from 30 days or 5 half-lives (which ever is longer) prior to baseline (randomization) to the end of the treatment period.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline (BL) in Unified Parkinson Disease (PD) Rating Scale (UPDRS) Motor Score
Time Frame: Baseline and Week 4 of the Maintenance Period (Study Week 17)
|
The UPDRS is a clinician based rating scale used to measure motor impairments and disability.
The UPDRS assesses six features of PD impairment.
These are evaluated using a combination of data collected by interview and examination of the participant.
One of the six features include the Part III - Motor Examination where scores can range 0-108 where the maximum score indicates the worse condition.
BL is defined as the last non-missing assessment measured on or before the first dose date.
The change from BL was calculated by subtracting the BL values from the individual post-randomization values.
The least squares(LS) means were estimated using the mixed model repeated measures(MMRM) adjusting for BL UPDRS motor score and race(white versus other) or by using the non-parametric rank analysis of covariance(ANCOVA).
