| NCT00004576 ↗ | Study of LY300164 for the Treatment of Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 2 | 2000-02-01 | This study will test the effectiveness of an experimental drug called LY300164 on improving Parkinson's disease symptoms, such as movement impairments and tremor, as well as involuntary movements produced by long-term treatment with levodopa. Patients with relatively advanced (Stage II to IV) Parkinson's disease between 30 and 75 years of age may be eligible for this 8-week study. Participants will have a complete medical history and physical examination, including blood tests and an electrocardiogram, and possibly brain magnetic resonance imaging (MRI), CT scan, and chest X-ray. Patients will stop taking all anti-parkinsonism medications except levodopa (Sinemet) and the experimental drug during the study. For the first 1 to 3 days, patients will be in the hospital for a levodopa "dose-finding" procedure. For this study, levodopa is infused through a vein for up to 8 hours, with symptoms monitored frequently to determine the doses that will produce two results: 1) the dose that is less than what is needed to relieve symptoms, and 2) the dose that relieves symptoms, but may produce dyskinesias. When these dose rates are determined, patients will begin treatment in one of two groups. One will take LY300164 3 times a day, along with levodopa, for 3 weeks. The second group will take placebo tablets (a look-alike tablet with no active ingredient) and levodopa on the same schedule as the LY300164 group. A brief medical examination and routine blood and urine tests will be done weekly. The drug dose will be increased every 3 to 4 days until significant side effects occur or the maximal dose is reached. Patients will be closely monitored for 4 hours after every increase. At the end of the 3 weeks, or when the maximal dose is reached, patients will be readmitted to the hospital for 2 to 3 days for a second levodopa dose-finding study, while continuing on LY300164 or placebo. After this test, patients will resume taking levodopa and the experimental drug or placebo as before for another 2 weeks. At the end of the 2-weeks, the entire procedure will be repeated in both groups, but the treatments will be switched-that is, the patients who were taking LY300164 will now take placebo, and the patients who took placebo will now take the drug. At the end of the second 3 weeks, the levodopa infusion procedure will be repeated once more. Throughout the study, parkinsonism symptoms and dyskinesias will be evaluated and blood samples will be drawn periodically to measure drug levels. |
| NCT00004733 ↗ | Timing of Levodopa Treatment in Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 3 | 1998-01-01 | 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). |
| NCT00006077 ↗ | Effects of Monoamine Reuptake Inhibitor NS2330 in Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 2 | 2000-08-01 | 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 for side effects for about 6 to 8 hours after taking the drug. At the beginning of weeks 2 and 5, the levodopa infusions will be repeated at the previously determined optimum rate. Throughout the study, parkinsonism symptoms, dyskinesias and depression will be evaluated. Blood and urine samples will be collected each week for standard safety tests, and blood will also be drawn periodically to measure NS2330 levels. |
| NCT00006337 ↗ | KW-6002 to Treat Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 2 | 2000-10-01 | This study will evaluate the effects of an experimental drug called KW-6002 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. This drug blocks the action of the neurotransmitter adenosine, thought to be involved in producing Parkinson's symptoms. Patients with relatively advanced (Stage II to IV) Parkinson's disease between 30 and 80 years of age may be eligible for this 7-week study. Participants will have a complete medical history and physical examination, including blood tests and an electrocardiogram, and possibly brain magnetic resonance imaging (MRI), CT scan, and chest X-ray. Patients enrolled in the study will, if possible, stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month before the study begins and throughout its duration. For the first 1 to 3 days, patients will be admitted to the NIH Clinical center to undergo a levodopa "dose-finding" procedure. For this study, patients will stop taking Sinemet and instead will have levodopa infused through a vein for up to 8 hours/day. During the infusions, the drug dose will be increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Symptoms will be monitored frequently to find two infusion rates: 1) one that is less than what is needed to relieve symptoms, and 2) one that relieves symptoms but may produce dyskinesias. This procedure will be repeated at the end of weeks 2, 4 and 6 of the study. When the patient's optimal dose is determined treatment will begin. Patients will take tablets or capsules containing KW-6002 or placebo (a look-alike pill with no active ingredient) once a day for 2 weeks, in addition to their regular Sinemet. All participants will receive placebo at least 2 weeks during the study; some patients will receive only placebo throughout the entire 7 weeks. At the end of weeks 1, 3 and 5, patients will be evaluated with a brief physical examination, routine blood and urine tests, and assessment of any adverse effects. Throughout the study, parkinsonian symptoms and dyskinesias will be evaluated and blood samples will be drawn periodically to measure drug levels. |
| NCT00009048 ↗ | EMD 128130 for the Treatment of Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 2 | 2001-01-01 | This study will evaluate the effects of an experimental drug called EMD 128130 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. EMD 128130 inhibits the function of serotonin, a chemical messenger thought to regulate dopamine release, and thus affect Parkinson's disease symptoms. Patients with relatively advanced Parkinson's disease between 30 and 80 years of age may be eligible for this 3-phase study. - Phase 1 - Baseline Evaluation Participants will have a medical history, physical examination, detailed neurologic evaluation, routine blood tests, urinalysis and an electrocardiogram. A chest X-ray and MRI or CT scan of the brain will be done if needed. In addition, an ACTH stimulation test will be done before and at the end of the study. For this test, a hormone called ACTH is injected into a vein. A small amount of blood is drawn before the injection and 30 and 60 minutes afterwards to measure levels of another hormone called cortisol. After these tests are completed, patients will, if possible, stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month before the study begins and throughout its duration. - Phase 2 - Levodopa and Apomorphine Dose Finding For 1 to 3 days, patients will be admitted to the NIH Clinical center to undergo a levodopa and apomorphine (a dopamine agonist) "dose-finding" procedure. For this procedure, patients will stop taking Sinemet and instead will have levodopa, and subsequently apomorphine, infused through a vein. During the infusions, the drug dose will be increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Symptoms will be monitored frequently to find two infusion rates: 1) one that is less than what is needed to relieve symptoms, and 2) one that relieves symptoms but may produce dyskinesias. - Phase 3 - Active Study Patients will begin the treatment phase within 3 months of the dose-finding phase. After a brief physical examination, routine blood tests, and evaluation of parkinsonism symptoms, patients will begin taking either EMD 128130 tablets or capsules or a placebo (a look-alike pill with no active ingredient) twice a day, along with Sinemet, for 3 weeks. All participants will receive placebo at least 1 week during the study, and about four patients, selected at random, will receive only placebo the entire 3 weeks. Levodopa and apomorphine infusions will be repeated at the end of weeks 1, 2 and 3 of Phase 3. The procedure for the infusions will be the same as in the dose-finding phase. Throughout the study, parkinsonian symptoms and dyskinesias will be assessed and blood samples will be drawn periodically to measure drug levels. Patients will return for a follow-up evaluation 2 weeks after the end of the study. |
| NCT00013624 ↗ | Riluzole to Treat Parkinson's Disease | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 2 | 2001-03-01 | This study will evaluate the effects of the drug riluzole on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. Riluzole blocks the action of the chemical messenger glutamate, thought to be involved in producing Parkinson's symptoms. The drug is currently approved to treat amyotrophic lateral sclerosis, another neurologic condition. Patients with relatively advanced Parkinson's disease between 20 and 80 years of age may be eligible for this 4-week study. Participants will have a complete medical history and physical examination, and a detailed neurological evaluation. The evaluations will include blood tests and an electrocardiogram, and possibly brain magnetic resonance imaging (MRI), CT scan, and chest X-ray. Participants will, if possible, stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month before the study begins and throughout its duration. For the first 1 to 3 days, patients will be admitted to the NIH Clinical Center to undergo a levodopa "dose-finding" procedure. For this study, patients will stop taking their oral Sinemet and instead will have levodopa infused through a vein for up to 8 hours/day. During the infusions, the levodopa dose will be increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Symptoms will be monitored frequently to find two infusion rates: 1) one that is less than what is needed to relieve symptoms (suboptimal rate), and 2) one that relieves symptoms but may produce dyskinesias (optimal rate). When the dose-finding phase is completed, treatment will begin. Patients will take riluzole or placebo (a look-a-like pill with no active ingredient) twice a day, along with their regular Sinemet, for 3 weeks. (All participants will receive placebo at some time during the study, and some patients will receive only placebo throughout the entire 4 weeks.) At the end of each week, patients will be readmitted to the hospital and receive the previous week's dose of riluzole or placebo in combination with a levodopa infusion at the rate determined in the dose-finding phase of the study. The procedure for the infusion will be the same as that for the dose-finding phase. The dose of riluzole will be increased until the optimum dose has been achieved or until side effects occur (at which time the dose will be lowered or the drug stopped). Throughout the study, parkinsonian symptoms and dyskinesias will be evaluated using standardized rating scales and blood samples will be drawn periodically to measure drug levels. |
