NCT02240030
This randomized, multicenter, placebo-controlled, double-blind study will evaluate the efficacy and safety of inhaled CVT 301 compared with placebo in PD patients experiencing motor response fluctuations (OFF phenomena) as an outpatient (i.e., at home) and in the clinic. Patients who successfully complete this study will be eligible to enroll into a 12 month treatment extension (CVT-301-004E) study.
NCT02361255
Parkinson's disease (PD) and Drug-induced Parkinsonism (DIP) can be clinically indistinguishable and DIP sometimes represents "unmasking of underlying PD. The objective of this study is to determine the relationship of underlying Parkinson's disease (PD) to the incidence and clinical outcome in DIP using non-motor assessments as a marker for nigrostriatal degeneration. Research Design: This is a nested case-control design to investigate risk factors associated with the development of DIP and persistent Parkinsonism after antipsychotic (AP) withdrawal (a potential clinical marker of underlying PD). Target enrollment is 45 subjects. Methodology: We will examine objective olfactory function (via objective olfactory testing), other non-motor symptoms of PD (via standardized validated questionnaires), and motor findings (via clinical exam and quantitative gait analysis) in: 1) DIP patients (30 subjects) compared to AP-treated patients without Parkinsonism (15 subjects) and 2) patients with persistent Parkinsonism compared to those whose symptoms resolve in the DIP cohort followed prospectively after a change in AP treatment. Additionally, in patients where it was performed clinically, we will evaluate dopamine transporter SPECT imaging (DaTI) as a marker of nigrostriatal integrity examining the ability of qualitative and semi-quantitative analysis to distinguish between pharmacologic and degenerative Parkinsonism. We will also measure serum uric acid and Apolipoprotein A1, two putative biomarkers in early PD, and examine their relationship with clinical and radiologic status.
NCT00105521
The purpose of this study is to test multiple doses of sarizotan to establish a dose with maximal safety and efficacy for treating treatment associated dyskinesia in Parkinson's disease participants.
NCT02136914
This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance. In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.
NCT01519271
Mild cognitive impairment, including difficulty with solving problems, planning, attention, or recalling information, can be a significant problem for individuals with Parkinson's disease. Even mild cognitive difficulties can lead to worse functioning, quality of life, depression, and difficulty for caregivers. Thus, ideally treatment at this stage would improve both cognitive symptoms and some of the other problems associated with these symptoms. Despite the fact that mild cognitive impairment is a serious problem for Parkinson's disease patients little is known about how best to treat it. This study is a 24-week clinical trial to see if a Food and Drug Administration (FDA)-approved drug, the Exelon (rivastigmine) Patch, is useful in treating mild cognitive impairment in patients with Parkinson's disease. Currently, the Exelon (rivastigmine) Patch is FDA-approved for the treatment of mild to moderate dementia in Alzheimer and Parkinson's disease patients.
NCT00632736
To evaluate the safety profile of ropinirole XL during long-term treatment in subjects with early and advanced Parkinson's disease
NCT00363727
This study evaluates how effective a new formulation of a marketed drug is in increasing the time to onset of dyskinesia (abnormal twisting, writhing movements) in patients with Parkinson's Disease who have been taking levodopa for less than 2 years.
NCT00936676
Eligible participants, who participated in the ADAGIO trial and who sign an approved informed consent form, will be enrolled into the study at their original study locations. participants who have stopped rasagiline therapy and in the opinion of the investigator will gain clinical benefit from restarting treatment can also be considered for enrollment in the Core follow-up study period. Use of any other anti-PD treatment is permitted as deemed necessary by the treating physician (according to the participants clinical status).
NCT03051607
Phase 3, international, multicenter, open-label 12 month safety study.
NCT03185481
The purpose of this study is to evaluate the long term safety and tolerability of PF-06649751 in Parkinson's disease patients who experience motor-fluctuations.
NCT02224664
This study will be an open label, dose escalation study to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of repeated daily quaque die (QD) doses given over 21 days (Day 3 to Day 23) to sequential cohorts of subjects with Parkinson's disease. Each cohort will have 2 study periods. For each cohort, subjects will enter Period 1 and if they meet criteria, approximately 12 subjects will be enrolled into Period 2 and dosed with PF 06649751. Based on results observed in a previous study, Cohorts 1 and 2 will not be conducted. Cohorts 3 - 6 will test doses uptitrated to 5 mg, 15 mg and 25 mg QD. Doses may be modified based on emerging safety, tolerability and PK data, but the maximum daily dose that will be given in any cohort will have PK predictions at steady state that are anticipated to be below toxicokinetic limits. An option for down titration to the previous dose level is available should the investigator consider that an AE is intolerable. Following down titration, a single up titration to the next dose level may be attempted if the subject remains symptom free for at least 48 hrs. Safety, tolerability and PK data of Cohort 3 will be reviewed prior to initiating the dosing in Cohorts 4 and 5. Available safety, tolerability and PK data up to Day 24 of at least 5 subjects from Cohorts 4 will be reviewed prior to initiating the dosing in Cohort 6.
NCT01167608
Parkinson's disease (PD) is the second most common neurodegenerative disorder in the elderly. In most people, the illness is complicated by co-occurring psychiatric problems such as depression and anxiety. These non-motor concerns negatively affect the course and management of the disease, often leading to poor outcomes for both patients and their families. Despite these deleterious consequences, psychiatric symptoms in PD are both underreported by patients as well as under-recognized and under-treated by health care providers. The primary purpose of this study is to identify and describe barriers to mental healthcare utilization for people with Parkinson's disease. Secondary objectives include the assessment of attitudes and preferences regarding the need for mental health services in the PD community and the acceptability of telehealth interventions as a method for improving access and quality of care. In order to accomplish these aims, participants will be asked to fill out an anonymous survey which will take about 15-30 minutes to complete. To best accommodate PD patients with varying levels of disability, participants will have the option to complete the survey online, on paper, or over the phone. The information obtained from this study will be used to support future treatment development efforts (i.e., phone and internet based interventions, community based trainings with local providers) intended to improve access and quality of mental health care for people with PD. To the best of the investigators knowledge, this is the first study to systematically examine barriers to mental healthcare utilization in PD in a national sample.
NCT02505737
There is a critical need for treatments that address depression and barriers to mental health care in Parkinson's disease (PD). This randomized-controlled trial will evaluate a 10-session telephone-guided cognitive behavioral self-help program (TH-CBT) for depression in PD (dPD). 72 people with dPD (and their caregivers) will receive either TH-CBT plus enhanced usual care (INTERVENTION GROUP) or enhanced usual care only (CONTROL GROUP). Groups will be compared at baseline, midpoint, endpoint, and 1 and 6 months post-treatment. Participants assigned to the control group with have the opportunity to receive the experimental intervention (TH-CBT) after the data collection period (e.g., after the 6-month follow-up evaluation). Given the public health impact of improved depression treatment in PD, the knowledge to be gained may be significant and the project could directly impact clinical practice.
NCT00219284
To assess motor function and quality of life (QoL) in Parkinson's disease (PD) subjects with end-of-dose wearing off, comparing immediate and delayed switch to carbidopa/levodopa and entacapone.
NCT01485172
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.

NCT02871427
This study seeks to evaluate the long-term safety and effectiveness of nelotanserin for the treatment of visual hallucinations (VHs) and Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) in subjects with Lewy body dementia (LBD).
NCT01738178
Parkinson's disease is a common neurodegenerative disorder in which patients experience progressive motor disability and many disabling non-motor symptoms. Recent studies have consistently found that people who do not use caffeine are at higher risk of developing Parkinson's disease. This suggests that caffeine may have potential as a treatment for PD. In a pilot study of caffeine for daytime sleepiness in PD, there was evident benefit on the motor manifestations of disease. There have been other lines of evidence that have suggested caffeine could be useful in PD. This study is to evaluate the efficacy of caffeine 200 mg BID vs matching placebo for motor and non-motor aspects of disease. This will be in three stages. In the first six-month stage, medications will be held constant, to see whether caffeine does have motor benefits. Then we will perform a four-year extension stage to define if the effects of caffeine persist (or even magnify), and to see if caffeine helps reduce dose of other PD meds and/or prevents their side effects. Finally, we will finish with a six-month stage in which we will place all patients on caffeine - this will allow us to assess caffeine's use in later disease, but more importantly, will assess whether early use of caffeine produces long term changes beyond its immediate effects.
NCT00986414
This phase IIb study is designed to determine the safe and efficacious dose or dose range of AFQ056 for the treatment of patients with moderate to severe Parkinson's disease with L-Dopa induced dyskinesias.
