Clinical Trials for Requip

Trial ID Title Status Sponsor Phase Summary
NCT00040209 JP-1730 to Treat Parkinson's Disease Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 2 This study will evaluate the effects of an experimental drug called JP-1730 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. JP-1730 affects chemical messengers believed to affect Parkinson's disease symptoms. Patients between 30 and 80 years of age with relatively advanced Parkinson's disease may be eligible for this 3-phase study. - Phase 1 - Baseline evaluation Participants will be evaluated with a medical history, physical examination, detailed neurologic evaluation, routine blood tests, urinalysis and an electrocardiogram. They will also have a 24-hour holter monitor (heart monitoring) and cardiology consultation. A chest X-ray and MRI or CT scan of the brain will be done if needed. Patients will, if possible, stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month before the study begins and throughout its duration. (If necessary, patients may use short-acting dopamine agonists, such as Mirapex and Requip.) - Phase 2 - Dose Finding Phase For 2 to 3 days, patients will be admitted to the NIH Clinical Center for a levodopa (a dopamine agonist) dose-finding procedure. For this procedure, patients stop taking Sinemet and instead have levodopa, and subsequently apomorphine, infused through a vein. During the infusions, the drug dose is increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Symptoms are monitored frequently to find the optimal dose. (Patients who have had dosing infusions in the last 3 months will not have to undergo this phase of the study.) - Phase 3 - Active Study Phase Within 3 months of the dose-finding phase, treatment will begin. Patients will receive seven doses of JD-1730 or placebo (an inactive substance) via puffs from an oral spray together with levodopa infusions over a 3-week period. The doses are given on days 1, 2, and 3 of the first week and then approximately twice a week for the next 2 weeks. For these doses, patients are hospitalized 4 days the first week and 2 days each for the next 2 weeks. All participants will receive placebo at some time during the study, and a few patients, selected at random, will receive only placebo the entire 3 weeks. The procedure for the infusions is the same as that for the dose-finding phase, with frequent evaluation of symptoms. Also, small blood samples are drawn up to three times each study day. At the end of the third week, patients will be discharged from the hospital. Their anti-parkinsonian medications may be readjusted, as needed. Patients will be contacted 2 weeks after the end of the study for a check on side effects and, if necessary, will be scheduled for a follow-up evaluation at the clinic. In addition to the above procedures, patients will be asked to have an optional lumbar a puncture (spinal tap) on the first and last days of the study to measure various brain chemicals and drug levels that cannot be measured in blood and urine. For this procedure, a local anesthetic is given and a needle is inserted in the space between the bones (vertebrae) in the lower back. About 2 tablespoons of fluid is collected through the needle.
NCT00076674 Levetiracetam Treatment of L-dopa Induced Dyskinesias Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 2 This study will evaluate the effects of levetiracetam (Keppra (Trademark) on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. Levetiracetam blocks certain protein receptors on brain cells and thus can change the spread of brain signals believed to be affected in patients with Parkinson's disease. Patients between 30 and 80 years of age with relatively advanced Parkinson's disease and dyskinesias due to levodopa therapy may be eligible for this 6-week study. Screening and baseline evaluation - Participants are evaluated with a medical history, physical examination and neurologic evaluation, blood tests, urinalysis, electrocardiogram (EKG), 24-hour holter monitor (heart monitoring), and cardiology consultation. A chest x-ray and MRI or CT scan of the brain are done if needed. If possible, patients stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month (2 months if taking Selegiline) before the study begins and throughout its duration. (If necessary, patients may use short-acting agents, such as Mirapex, Requip or Amantadine.) Dose-finding phase - Patients are admitted to the NIH Clinical Center for 2 to 3 days for a levodopa "dose-finding" procedure. For this test, patients stop taking Sinemet and instead have levodopa infused through a vein. During the infusions, the drug dose is increased slowly until parkinsonian symptoms improve or unacceptable side effects occur or the maximum study dose is reached. Symptoms are monitored frequently. (Patients who have had dosing infusions in the last 3 months do not have to undergo this phase of the study.) Active study phase - Patients are randomly assigned to take levetiracetam or placebo ("sugar pill") twice a day for 6 weeks. At the end of weeks 1, 2 4, and 5, patients come to the clinic for blood tests, an EKG, and a review of adverse side effects. At the end of weeks 3 and 6, patients are hospitalized to study the response to treatment. They again stop taking Sinemet and selegiline and their ability to perform motor tasks is evaluated. They are then placed on an L-dopa infusion for 10 hours. Placebo may be infused at various times instead of L-dopa. Motor symptoms are evaluated several times during the infusion. Blood is drawn once during the infusion for research studies. Lumbar puncture - Patients undergo a lumbar puncture (spinal tap) at the end of weeks 1 and 4 to measure certain brain chemicals and drug levels. For this test, a local anesthetic is given and a needle is inserted in the space between the vertebrae in the lower back. About 2 tablespoons of fluid is collected through the needle. Magnetic resonance imaging (MRI) - Patients with changing disease activity may undergo MRIs at baseline, at the end of week 1 and at the end of the study to show changes in the brain. The patient lies in a narrow cylinder (the scanner) that uses radio waves and a magnetic field to produce images of the brain, which show structural and chemical changes. Follow-up - 2 weeks after the study ends, patients are contacted by phone for a review of side effects or they return to the clinic for an evaluation.
NCT00086294 ACP-103 to Treat Parkinson's Disease Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 2 This study will evaluate the effects of an experimental drug called ACP-103 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term levodopa treatment. ACP-103 changes the spread of certain brain signals that are affected in patients with Parkinson's disease. Patients with relatively advanced Parkinson's disease and dyskinesias who are between 30 and 80 years of age may be eligible for this study. Candidates are screened with a complete medical history and physical examination, neurological evaluation, blood and urine tests, and electrocardiogram (ECG). A brain magnetic resonance imaging (MRI) scan, CT scan, and chest x-ray may be done if medically indicated. Patients enrolled in the study will, if possible, stop taking all antiparkinsonian medications for one month (2 months for Selegiline) before the study begins and throughout its duration. Exceptions are Sinemet (levodopa/carbidopa), Mirapex (pramipexole) and Requip (ropinirole). Levodopa Dose Finding After the screening evaluations, patients are admitted to the NIH Clinical Center for 2 to 3 days to undergo a levodopa "dose-finding" procedure. For this test, patients stop taking Sinemet and instead have levodopa infused through a vein. During the infusion, the drug dose is increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Side effects are monitored closely during the infusions, and parkinsonian symptoms are evaluated frequently during and after the infusions. The infusions usually begin early in the morning and continue until evening. Once the infusion is finished, patients resume taking their regular oral Sinemet dose. The infusions are repeated once a week during 1-day inpatient evaluations. Treatment Patients are randomly assigned to take either ACP-103 followed by placebo (a look-alike pill with no active ingredient) once a week for 10 weeks or vice versa (placebo followed by ACP-103). Patients are admitted to the Clinical Center for each dose. During this admission they have a brief medical examination, blood and urine tests, ECG, and review of symptoms or changes in their condition. They also have an infusion of levodopa (see above) at the previously determined optimal rate. Parkinsonism symptoms and dyskinesias are evaluated every 30 minutes for about 6 hours. At the end of the infusions and ratings, patients are discharged home with their regular Parkinson's medications until the following visit. Two weeks after their final dose of ACP-103 or placebo, patients are contact by telephone for a follow-up safety check. At that time, the investigator may ask the patient to return to the clinic for closer evaluation.
NCT00108667 Talampanel to Treat Parkinson's Disease Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 2 This study will evaluate the effects of the experimental drug talampanel on dyskinesias (involuntary movements) that develop in patients with Parkinson's disease as a result of long-term treatment with levodopa (Sinemet). The drug will be tested alone and in combination with amantadine-a drug commonly used to alleviate dyskinesias. Patients between 21 and 80 years of age with Parkinson's disease and dyskinesias may be eligible for this study. Screening and baseline evaluation. Participants are evaluated with a medical history, physical and neurologic examinations, blood and urine tests, electrocardiogram (EKG) and pregnancy test, if applicable. A chest x-ray and MRI or CT scan of the brain are done if needed. Patients stop taking all antiparkinsonian medications for one month (2 months if taking Selegiline) before the study begins and throughout its duration, except for certain medicines allowed, including Sinemet, Mirapex and Requip. Amantadine can be taken up to 1 week before beginning the study. Dose-finding phase. Patients are admitted to the NIH Clinical Center for 2 to 3 days for a levodopa "dose-finding" procedure. For this test, patients stop taking Sinemet and instead have it infused through a vein. During the infusions, the drug dose is increased slowly until parkinsonian symptoms improve or unacceptable side effects occur or the maximum study dose is reached. Symptoms are monitored frequently. At given times during the infusion, saline is given instead of Sinemet. The infusions usually begin in the early morning and continue until evening. Patients resume taking Sinemet between infusions. (Patients who have had dosing infusions in the last 3 months do not have to undergo this phase of the study.) After the dose-finding phase, patients are randomly assigned to take placebo (a "sugar pill") or talampanel. Those taking talampanel also receive amantadine at their usual dosages. At some point in the study, amantadine is replaced with placebo. Patients in the talampanel group also receive placebo for portions of the study. Active study phase. At study weeks 1, 5 and 7, patients are admitted to the Clinical Center overnight for a levodopa infusion with talampanel or placebo. The day before the infusion, patients have a brief physical examination, blood and urine tests, an EKG, and a review of symptoms or changes in their condition. The next day, they receive an infusion of levodopa at the dose determined in the dose-finding phase. Then they take a pill containing either talampanel or placebo. Their parkinsonian symptoms and dyskinesias are evaluated and videotaped every 30 minutes for about 6 hours. Blood is drawn and an EKG is obtained. At the end of the infusions and ratings, patients resume their regular Parkinson's medications and are given a new supply of study medications to take home. At weeks 2, 3, 4 and 6, patients come to the Clinical Center for a review of drug side effects. They have blood drawn and receive a new supply of study medications that last until the next visit. Follow-up. Two weeks after the study ends, patients are contacted by phone for a review of side effects or they return to the clinic for an evaluation.
NCT00260793 Open Label High Dose Ropinirole (Requip) Study for Patients With Parkinson's Disease Unknown status Colorado Neurology Phase 3 The purpose of this research study is to see if subjects with Parkinson's disease who are experiencing motor fluctuations ("on" and "off" states) and dyskinesias (involuntary excessive movements) would benefit from a higher dose of Requip as compared to the maximum FDA approved dose of dopamine agonist drugs (including Requip, Mirapex, and Permax). Requip as used in this study is investigational, which means it has not been approved by the US Food and Drug Administration (FDA) at this dose level.
