Effects of Monoamine Reuptake Inhibitor NS2330 in Parkinson's Disease
NCT00006077 · View on ClinicalTrials.gov ↗
Study Summary
This study will evaluate the effects of an experimental drug called NS2330 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. This drug prevents the neurotransmitter dopamine from entering nerve cells. Patients between 18 and 75 years old who have moderately advanced Parkinson's disease and motor problems resulting from levodopa therapy may be eligible for this 5-week study. Candidates will have a complete medical history and physical examination with a detailed neurological evaluation. If needed, some patients will undergo a magnetic resonance imaging (MRI) or computerized tomography (CT) scan of the brain and a chest X-ray. All patients will have blood and urine tests and an electrocardiogram (EKG) and will take a written test for evaluation of depression. Patients enrolled in the study will, if possible, stop taking all antiparkinson medications except levodopa (Sinemet) for one month before the study begins and through its duration. For the first 1 to 3 days, patients will undergo a levodopa "dose-finding" procedure. For this study, patients will stop taking their usual oral levodopa medicine and instead will have levodopa infused through a vein for up to 12 hours. During the infusions, the drug dose will be increased slowly until either 1) parkinsonism symptoms improve, 2) dyskinesias appear, 3) unacceptable side effects occur, or 4) the maximum study dose is reached. When the patient's optimal dose is determined, treatment will begin. Patients will take three pills containing NS2330 or placebo (a look-alike pill with no active ingredient) 3 days a week for up to 5 weeks, in addition to their regular levodopa medication. All participants will receive placebo at some point in the study; some patients will receive only placebo throughout the entire 5 weeks. On treatment days, patients will have a brief medical examination before receiving the drug and will then be monitored

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00006077
The ClinicalTrials.gov registry entry for NCT00006077 describes a study currently listed as completed. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 50 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Parkinson's Disease appearing as the primary indexed condition, and to 2 interventions — of which NS2330 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00006077 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
