OASIS: OpicApone Sleep dISorder
Study Details
Study Description
Brief Summary
The aim of this study is to To investigate in an exploratory manner the efficacy of 50 mg opicapone when administered with the existing treatment of levodopa (L-dopa) plus a dopa decarboxylase inhibitor (DDCI), in Parkinson's disease (PD) patients with end-of-dose motor fluctuations and associated sleep disorders

| Phase 4 |
Detailed Description
This is an open-label, single-arm, multi-centre, interventional clinical study in PD patients with end-of-dose motor fluctuations and associated sleep disorders. The study consists of a 1-week screening period, a 6-week treatment period and 2 weeks of follow-up period. Expected duration of treatment for the individual patient is up to 6 weeks.

Outcome Measures
Primary Outcome Measures
- Total score of Parkinson's Disease Sleep Scale - version 2 (PDSS-2) [Up to 6 weeks]
Parkinson's Disease Sleep Scale version 2 (PDSS-2) is a patient-completed clinical rating scale that assesses the frequency of sleep disturbances over the past week. Each question is scored between 0 ("never") and 4 ("very often"), and a total score is calculated by summing a patient's responses to each of the 15 questions (minimum 0 to maximum 60)
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Able to comprehend and willing to sign an informed consent form and to comply with all aspects of the study.
-
Male or female patients aged 30 years or older.
-
Diagnosed with idiopathic PD according to the UK Parkinson's Disease Society Brain Bank Clinical Diagnostic Criteria (2006) or according to MDS Clinical Diagnostic Criteria (2015).
-
Signs of "wearing-off" phenomenon (end-of-dose motor fluctuations) with average total daily OFF time while awake of at least 1.5 hours, excluding the early morning pre-first dose OFF, despite optimal anti-PD therapy (based on investigator's assessment).
-
Disease severity Stages I-III (modified Hoehn & Yahr staging) at ON.
-
Experiencing PD associated sleep disorders for at least 4 weeks prior to V1.
-
Total PDSS-2 score ≥ 18.
-
Treated with 3 to 8 intakes per day of L-dopa/DDCI (which may include a slow-release formulation), on a stable regimen for at least 4 weeks before V1.
-
In case of any other anti-PD treatment, it should be on a stable regimen for at least 4 weeks before V1, and not likely to need any adjustment until V4.
-
No change in the chronic treatment regimen within the last 4 weeks before V1 of the following medication: sedatives, hypnotics, anti-depressants, anxiolytics or other medications prescribed for the treatment of sleep disorders
-
For females: Postmenopausal for at least 2 years before V1, surgically sterile for at least 6 months before V1, or practicing an effective method of contraception until V4. Female patients who request to continue with oral contraceptives must be willing to use non-hormonal methods of contraception in addition during the course of this study.
For males: Male patients who are sexually active with a partner of childbearing potential must use, with their partner, a condom plus an approved method of highly effective contraception during the treatment period until V4.
-
Have filled-in self-rating diary in accordance with the diary instructions and with ≤ 3 errors per day when awake, in the 3 days preceding V2a/V2b.
-
With at least 1.5 OFF hours per day, excluding the early morning pre-first dose OFF period (i.e. the time between wake-up and response to the first L dopa/DDCI dosage), as recorded in at least 2 of the 3 days in the self-rating diary for the 3 days preceding V2a/V2b.
-
Total PDSS-2 score ≥ 18.
-
Adequate compliance to relevant (PD and sleep disorders) concomitant medication during the screening period (based on the investigator's judgment).
Exclusion Criteria:
-
Non-idiopathic PD (atypical parkinsonism, secondary [acquired or symptomatic] parkinsonism, Parkinson-plus syndrome).
-
Severe and/or unpredictable OFF periods, according to investigator judgement.
-
Major/prominent non-PD-related sleep disorders (e.g. sleep apnoea or narcolepsy).
-
Treatment with prohibited medication: entacapone, tolcapone, monoamine oxidase (MAO) inhibitors (except selegiline up to 10 mg/day in oral formulation or 1.25 mg/day in buccal absorption formulation, rasagiline up to 1 mg/day or safinamide up to 100 mg/day), or antiemetics with antidopaminergic action (except domperidone) within the last 4 weeks before V1 or likely to be needed at any time until V4.
-
Treatment with apomorphine within the last 4 weeks before V1 or likely to be needed at any time until V4.
-
Previous or current use of opicapone.
-
Previous or planned (until the end of this study) L-dopa/carbidopa intestinal gel infusion, deep brain stimulation or stereotactic surgery (e.g. pallidotomy, thalamotomy).
