A Study to Assess the Effect of Safinamide on Levodopa Pharmacokinetics

2014-08-27 03:17:31 | BioPortfolio

Summary

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 of vital signs (blood pressure, pulse, body temperature), recording of ECGs and questioning to find out how the study participants are feeling. Furthermore, blood samples will be drawn and urine tests will be performed repeatedly for safety purpose during the course of the study.

The results of this clinical trial may be used for the drug registration of safinamide in the future.

Safinamide in Idiopathic Parkinson's Disease (IPD) With Motor Fluctuations, as add-on to Levodopa

Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) defi...

Safinamide in Levodopa Induced Dyskinesia in Parkinson's Disease Subjects

The purpose of this research trial is to determine in Parkinson's disease patients if safinamide (experimental drug) can attenuate the dyskinesia induced by levodopa. The word "experimenta...

Carbidopa/Levodopa/Entacapone Versus Immediate Release (IR) Carbidopa/Levodopa on Non-Motor Symptoms in Patients With Idiopathic Parkinson's Disease

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 ...

A Study to Evaluate Fixed Dose Carbidopa/Levodopa/Entacapone Versus Immediate Release Carbidopa/Levodopa

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 ...

Intravenous Levodopa for the Diagnosis of Parkinson's Disease

Patients with Parkinson's disease have low levels of the neurotransmitter dopamine. Dopamine is responsible for motor function and normal physical activity. Patients with Parkinson's dise...

Medical and Biotech [MESH] Definitions

An inhibitor of DOPA DECARBOXYLASE, preventing conversion of LEVODOPA to dopamine. It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA. It has no antiparkinson actions by itself.

A selective, irreversible inhibitor of Type B monoamine oxidase. It is used in newly diagnosed patients with Parkinson's disease. It may slow progression of the clinical disease and delay the requirement for levodopa therapy. It also may be given with levodopa upon onset of disability. (From AMA Drug Evaluations Annual, 1994, p385) The compound without isomeric designation is Deprenyl.

An inhibitor of DOPA DECARBOXYLASE that does not enter the central nervous system. It is often given with LEVODOPA in the treatment of parkinsonism to prevent the conversion of levodopa to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system and reducing the required dose. It has no antiparkinson actions when given alone.

A deaminated metabolite of LEVODOPA.

A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.
