29 Clinical Trials for Various Conditions
The primary objective is to determine the tolerability and efficacy of a low-dose ketamine infusion for the treatment of Levodopa-Induced dyskinesias (LID), both acutely and during post-infusion evaluation (week 2-6), as measured by a change in patient diaries of dyskinesia and the UDysRS. Secondary objectives include observing the effects of ketamine on various symptoms of Parkinson's disease and Levodopa side effects. This includes the duration of "off," "on without dyskinesia," and "troublesome dyskinesia" time during waking hours, effects on chronic and acute pain, quality of life, and other general PD symptoms as noted in the Unified Parkinson's Disease Rating Scale. There is no highly effective treatment for levodopa-induced dyskinesia. This research study will use intermittent infusions of ketamine, on 10 volunteer subjects, which could provide significant improvement in dyskinesia utilizing a novel mechanism of action compared to current treatment strategies. Positive results in this study could lead to new novel treatments for dyskinesia and further development for other PD symptoms such as depression and pain.
A Multi-Center, Phase II, Randomized, Double-Blind, Prospective, Active Placebo-Controlled Trial of Sub-Anesthetic Intravenous Infusion of Ketamine to Treat Levodopa-Induced Dyskinesia in Subjects with Parkinson's Disease.
This is a Phase 2b study investigating the efficacy and safety of mesdopetam as adjunct therapy on daily ON-time without troublesome dyskinesia in patients with Parkinson disease. Mesdopetam is taken for 84 days.
In this study, the investigators will examine the association of statin use and dyskinesia in a convenience sample Parkinson's disease patients in the Veterans Administration Health Care System.
This is a multicenter, randomized, three-arm, parallel-group, double-blind, placebo-controlled, study to evaluate the efficacy, safety and pharmacokinetics (PK) of pridopidine vs. placebo for the treatment of Levodopa Induced Dyskinesia (LID) in patients with Parkinson Disease.
The primary objective of this study is to evaluate the efficacy of buspirone in combination with amantadine in reducing levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD).
The purpose of this study is to evaluate the safety, tolerability and efficacy of eltoprazine to treat levodopa-induced dyskinesia in patients with Parkinson's disease
This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa-induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance. In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.

To evaluate the efficacy, safety, and tolerability of AVP-923 capsules containing 45 mg dextromethorphan and 10 mg quinidine (AVP-923-45) compared to placebo for the treatment of levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD).
This is a multi-center, randomized, double-blind, placebo-controlled, 4-arm parallel group study to evaluate the tolerability and efficacy of each of three dose levels of ADS-5102 oral capsules, an extended release formulation of amantadine, dosed once daily for the treatment of levodopa-induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) higher amantadine plasma concentrations during daytime hours when dyskinesia as well as motor and non-motor symptoms of PD are most problematic, ii) low amantadine plasma concentrations overnight, which may reduce the sleep disturbances and vivid dreams occasionally associated with amantadine, and iii) a reduced initial rate of rise in plasma concentration, which is expected to improve overall tolerability of amantadine.
The primary objective of the study is to evaluate the safety and tolerability of ADX48621 in Parkinson's disease patients following four weeks of dosing. The secondary objectives of the study include the evaluation of the efficacy of ADX48621 compared with placebo in reducing levodopa induced dyskinesia in patients with Parkinson's; the evaluation of the effect of ADX48621 on symptoms of Parkinson's disease and patient ability to function, and the evaluation of the effect of coadministration of ADX48621 on L-dopa efficacy.
Levodopa is the main drug treatment for Parkinson's disease. Levodopa can cause unwanted and uncontrolled movements called dyskinesias (LID). The severity of these movements can range from subtle to extremely debilitating. These movements may or may not interfere with normal activities such as putting on a coat or brushing ones teeth. Current estimates of the occurrence rate of LID range from 12 % to 100% after one year of levodopa treatment. These estimates used reporting mechanisms such as self-report and doctor-reported. These reporting mechanisms are not reliable. We will use an objective measure of dyskinesia in the first 5 years of treatment for Parkinson's disease. The purpose of this protocol is to use an objective measure to estimate dyskinesia onset.
Nearly all Parkinson's disease (PD) patients eventually develop abnormal and unwanted movements (dyskinesias; LID) caused by the gold standard treatment, Levodopa. The severity of these movements can range from subtle to extremely debilitating and may or may not interfere with normal activities such as putting on a coat or brushing ones teeth. The purpose of this study is to demonstrate the validity and reliability of objectively measuring dyskinesia with a forceplate.
The ultimate goal of this proposal is to reduce dyskinesia in Parkinson's Disease (PD) patients. Dyskinesias are abnormal movements, often caused by the standard treatment for PD symptoms, levodopa. In this study, we will test if biochemical devices are equal to the clinical rating system in measuring dyskinesias.
This is a 105-week open-label study to evaluate the safety and tolerability of ADS-5102 oral capsules, an extended release formulation of amantadine, in Parkinson's Disease (PD) patients with Levodopa Induced Dyskinesia (LID).
This study was terminated early due to slow enrollment with 87 of 162 planned subjects enrolled. The purpose of this multi-center, randomized, double-blind, parallel-group, 16 week study is to compare the efficacy and safety of two different dose levels of Amantadine Extended Release Tablets to placebo for the treatment of levodopa induced dyskinesia in patients with Parkinson's disease.
The purpose of this multi-center, randomized, double-blind, parallel-group, 26 week study is to compare the efficacy and safety of two different dose levels of Amantadine Extended Release Tablets to placebo for the treatment of levodopa induced dyskinesia in patients with Parkinson's disease.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in patients with a diagnosis of Parkinson's Disease consistent with the UK Parkinson's Disease Society (UKPDS) Brain Bank diagnostic criteria, who are experiencing wearing off symptoms and levodopa-induced dyskinesia.
This open-label study is designed to assess the long-term safety and tolerability of dipraglurant in PD patients for up to 52 weeks (at doses of 150-300 mg per day) for patients that have completed an Addex sponsored double-blind clinical trial of dipraglurant.
This study is designed to evaluate the safety and efficacy of dipraglurant in PD patients with dyskinesia (randomized 1:1 to receive active or placebo) for 12 weeks (1 week at 150 mg per day and 11 weeks at 300 mg per day). The primary efficacy assessment will be based on the Unified Dyskinesia Rating Scale (UDysRS). Patients who complete the 12-week blinded treatment period may have the option to roll into an open-label safety extension study for an additional 12-month treatment period.
The study is designed to answer the question: will nicotine at doses that do not cause serious side effects, show feasibility in treatment of levodopa-induced dyskinesia in patients with Parkinson's disease?
The primary objective of this study is to determine whether intramuscular injections of botulinum toxin type A (Botox®) in selected cervical muscles at antidystonic dosages can reduce levodopa-induced peak-dose dyskinesias (LID) in the cervical region in adult patients with idiopathic Parkinson's disease. It is hypothesized that the intramuscular injection of antidystonic doses of botulinum toxin into cervical muscles will decrease the duration and severity of LID in the cervical region in patients with Parkinson's disease (PD).
This study is to evaluate long-term safety, tolerability and efficacy for AFQ056 in patients who have completed an AFQ056A study in Parkinson's disease L-dopa induced dyskinesias (PD-LID).
This study will assess the efficacy and safety of modified release AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)
This study will assess the efficacy and safety of AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)
The purpose of this study is to generate long-term safety, tolerability and efficacy data for AFQ056 in patients who have participated in and completed any AFQ056 phase II study in PD-LID (Parkinson's disease, L-dopa induced dyskinesias).
This Phase IIb exploratory study is designed to determine whether AFQ056 is safe and effective and whether it can increase the therapeutic window of L-dopa in patients whose control of their Parkinson's Disease symptoms is limited by the development of dyskinesia induced by use of L-dopa.
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.
