Trial overview
Official title: A fixed dose, dose response study for ropinirole prolonged release (PR) in patients with early stage Parkinson's Disease
Trial description: This study is a fixed dose, dose response study to characterize the doseresponse for ropinirole PR in early stage PD patients (Hoehn & Yahr stages I-III). Afterscreening and baseline assessments, subjects will be randomized to one of six final targettreatment groups (placebo, 2, 4, 8, 12 or 24mg/day ropinirole PR). The study will consistof a screening period, an up-titration period, a maintenance period, a down titrationperiod and a follow up period. This study utilizes change from baseline in the UPDRSmotor score as the primary endpoint, in line with that used in the ropinirole PRmonotherapy pivotal study (SK&F101468/168). Clinical review of the primary andsecondary endpoints will be performed in order to establish the lowest maximallyeffective therapeutic dose.

- Diagnosis of idiopathic Parkinson’s disease (according to modified Hoehn & Yahr
- criteria Stages I-III.)
- Subjects with Parkinson’s disease in whom dopaminergic therapy is not warranted at
- the time of screening.
Inclusion and exclusion criteria
Inclusion criteria:
- Diagnosis of idiopathic Parkinson’s disease (according to modified Hoehn & Yahr criteria Stages I-III.)
- Subjects aged 30 years or greater at screening. Women of child-bearing potential must be practicing a clinically accepted method of contraception during the study and for at least one month prior to randomization and one month following completion of the study. Acceptable contraceptive methods include abstinence, oral contraception, injectable progestogen, implants of levonorgestrel, estrogenic vaginal ring, percutaneous contraceptive patches, surgical sterilisation, male partner sterilization, intrauterine device [IUD], or double barrier method: condom or occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository.
- A baseline UPDRS motor score of at least 10.
- Limited prior exposure to low or moderate doses of L-DOPA (up to 3 months in total) or dopamine agonists including ropinirole (up to 6 months in total) is allowed provided treatment is discontinued for a minimum of 4 weeks prior to screening.
- Provide written informed consent for this study.
- Be willing and able to comply with study procedures.
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 with prior or current major psychosis (e.g., schizophrenia or psychotic depression) e.g. scoring 3 or 4 on UPDRS item 2 [thought disorder] or item 3 [depression].
- Subjects with severe clinical dementia e.g. scoring 3 or 4 on UPDRS item 1 [mentation].
- Subjects with severe dizziness or fainting due to postural hypotension on standing.
- Subjects with a personal history of melanoma.
- Subjects with clinically significant abnormalities in laboratory or ECG tests at Screening. If findings are outside the normal range and the subject is included, it must be documented by the investigator that the findings are not of clinical significance.
- Subjects diagnosed with an impulse control disorder. The modified MIDI will be conducted at screening. Subjects who score positive for this screen must be referred to a specialist for diagnostic evaluation prior to enrolling (screening) in the study.
- Subjects with an active suicidal plan/intent or have had active suicidal thoughts in the past 6 months. Subjects with a history of suicide attempt in the last 2 years or more than 1 lifetime suicide attempt.
- Current alcohol or drug dependence.
- Definite or suspected personal or family history of clinically significant adverse reactions or hypersensitivity to ropinirole (or to drugs with a similar chemical structure) that would preclude long-term dosing with ropinirole.
- Withdrawal, introduction, or change in dose of hormone replacement therapy and/or any drug known to substantially inhibit CYP1A2 (e.g. ciprofloxacine, fluvoxamine, cimetidine, ethinyloestradiol) or induce CYP1A2 (e.g. tobacco, omeprazole) within 7 days prior to baseline (randomization).
- 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.
