The study hypothesis is that continuous ND0611 increases the bioavailability of levodopa and therefore the levodopa area-under-the-concentration-curve values, half-life, and trough concentrations The study will help determining the safety and tolerability of ND0611 and determine the pharmacokinetic profile of levodopa following multiple oral dosing of levodopa/carbidopa (LD/CD) and continuous delivery of ND0611

The investigators' hypothesis is that levodopa infusion may alleviate hyperhidrosis and orthostatic hypotension.
The purpose of this study is to determine the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 100 mg/benserazide 25 mg (Madopar® HBS 125).
This is a phase IIa study to assess the safety, tolerability, plasma pharmacokinetics and efficacy of intermittent oral administration of standard levodopa/carbidopa (LD/CD) vs.semi-continuous intra-oral administration of levodopa/carbidopa in patients with advanced Parkinson's disease (PD) who suffer motor fluctuations.The objective of this study is to assess the plasma pharmacokinetics (PK) of continuous intra-oral administration of LD/CD vs. intermittent administration of st...
The purpose of this study is to achieve approval for the use of carbidopa/levodopa/entacapone in early Parkinson's disease (PD) by demonstrating that when used as initial levodopa therapy in early PD, carbidopa/levodopa/entacapone provides significantly greater symptomatic benefit than immediate release carbidopa/levodopa administered at the same levodopa dosage level of 100 mg three times a day (t.i.d.).
The purpose of the study is to investigate PK of levodopa in plasma after repeated doses of 3 levodopa formulations given in combination with carbidopa and ODM-104 and compared to the PK of standard IR and CR levodopa formulations in the same combination.
The CELC200A2401 study has been designed in order to evaluate the hypothesis that administering the combination carbidopa/levodopa/entacapone at the time that levodopa therapy is initiated results in a decrease in the risk of the development of motor complications for the patient with PD.
The objective of this study is to investigate the effect of safinamide on levodopa blood levels, both after single and multiple dosing of safinamide . A further objective of the study is to assess the safety and tolerability of safinamide when given together with levodopa in the applied regimen. For that purpose, all study participants will undergo intensive blood sampling for investigation of levodopa levels and various tolerability examinations, such as the measurement...
The purpose of this study is to establish the efficacy of 20 mg/day and 40 mg/day doses of istradefylline for reducing the mean total hours of awake time per day spent in the OFF state in patients with advanced Parkinson's disease (PD) treated with levodopa.
The ELLDOPA study is a controlled clinical trial in patients with newly diagnosed PD to determine the optimal timing and dosing with levodopa (Sinemet or its generic equivalents).
The purpose of this study is to test the effects of carbidopa/levodopa/entacapone compared to the effects of immediate-release carbidopa/levodopa on end-of-dose wearing off in persons who have Parkinson's disease.
This study examines the effect of treatment of levodopa/entacapone on quality of life, as measured by the Parkinson's Disease-Questionnaire 8 (PDQ-8), in Parkinson's disease patients with no or minimal, non-disabling motor fluctuations.
The purpose of this study is to investigate the pharmacokinetics of levodopa, carbidopa, 3-OMD and ODM-104 after repeated doses of levodopa, carbidopa and ODM-104: an open, randomised, multicentre study with crossover design in healthy males and females.
IRL790 is an experimental small molecule compound with psychomotor stabilizing properties. The primary target is the dopamine D3 receptor, a target implicated in the generation of levodopa-induced dyskinesia, a side-effect frequently occurring with long-term levodopa treatment in patients with Parkinson's disease. In experimental animals IRL790 potently reduced levodopa-induced involuntary movement without impairing the antiparkinsonian effect of levodopa. The primary pu...
Both Continuous intrajejunal Levodopa Infusion (CLI) and Deep Brain Stimulation (DBS) are accepted therapies for the treatment of advanced Parkinson's disease (PD). To date, no comparative studies have been executed. The INVEST study is an open label randomised controlled trial with cost-effectiveness as primary outcome. Secondary outcomes will be quality of life, neurological impairments, among others.
This study is designed to determine whether levodopa will lead to an improvement in the development and tremor in children with Angelman syndrome (AS). It has been suggested that levodopa, a medication that is usually used to treat Parkinson disease in adults, may help children with AS in their overall development and reduce the tremor that some of them have. If levodopa is found to be beneficial for children with AS, this could lead to a new treatment for AS. Fu...
To find out if a single dose of Parcopa®, a form of levodopa that dissolves in your mouth, works faster than regular oral levodopa which is swallowed, in fluctuating PD patients.
The purpose of this study is to determine the safety, tolerability, pharmacokinetic and pharmacodynamic effects of single doses of Neu-120 in Parkinson's disease patients with levodopa-induced dyskinesia.
The primary objective of this study is to examine the effect of levodopa-carbidopa intestinal gel (LCIG) compared with optimized medical treatment (OMT) on dyskinesia in participants with advanced Parkinson's disease (PD).
This is a multi-center, international, open-label, safety study of ND0612, a solution of levodopa/carbidopa (LD/CD) delivered via a pump system as a continuous SC infusion in subjects with advanced Parkinson's Disease.
The study aims to investigate the effects of a short computerized training as a therapeutic add-on to standard therapy in patients with alcohol-use disorder.
In this study the aim is to evaluate the outcome of deep brain stimulation (DBS) and continuous intraduodenal levodopa therapy in patients with advanced Parkinson' disease by using Parkinson's KinetiGraph™ device which is a movement and acceleration measuring device. In this study we also evaluate the usability of Parkinson's KinetiGraph™ device by comparing it with written patient diaries.
This study is designed to determine the highest dose of levodopa/carbidopa that can be tolerated without any serious side effects by children with Angelman syndrome. It has been hypothesized that levodopa may lead to an improvement in the neurodevelopment and abnormal movements (e.g. tremors) in children with Angelman syndrome. Data from this study will be used to design a phase II trial to determine the efficacy of levodopa in treating children with Angelman syndrome.
The purpose of this study is to confirm that the dose levels and dosing frequency utilising the new Stalevo strengths would result into more stable levodopa plasma levels. Therefore, it is anticipated that when lower dose of Stalevo is administered after the first higher dose of Stalevo, this would result in equally high levodopa maximum concentration values (Cmax) after each dose throughout the day compared to Cmax after the first dose.
The purpose of this study is to determine whether oral intake of COMT inhibitors affects the smooth plasma levodopa levels achieved by intestinal levodopa/carbidopa infusion in advanced Parkinson's disease patients. The hypothesis is that COMT inhibitors make plasma concentrations of levodopa more fluctuating.
