Filter by:The primary objective of this study is to evaluate the efficacy of valbenazine versus placebo on improving chorea in participants aged 6 to 70 years who have dyskinesia due to cerebral palsy (DCP) with choreiform movements.
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.
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).

Levodopa-induced dyskinesia is a common problem in Parkinson's disease (PD). In particular, targeting non-dopaminergic systems may be an option for reducing dyskinesia without worsening motor symptoms. One such target may be histamine. The central histaminergic system is involved in diverse biological functions including thermoregulation, eating, and sleep; a role in motor activity is suggested by strong histaminergic innervation of the basal ganglia. Histamine H2 receptors are highly expressed in the striatum, particularly on the GABAergic striatal-pallidal and striatal-nigral pathways Histamine H2 stimulation modulates acetylcholine release. Previous studies have demonstrated that blocking acetylcholine with anticholinergic agents can induce chorea. The investigators propose that histamine H2 receptor stimulation decreases acetylcholine in the striatum and increases activity of the direct striatal output pathway, a key component of the neural mechanisms underlying dyskinesia. The investigators hypothesise that H2 antagonists would reduce activity of the direct striatopallidal pathway and so potentially reduce levodopa-induced chorea Famotidine has also been assessed in schizophrenia in a small cases series to treat schizophrenia, with tolerability. Clinical experience thus suggests the suitability of using this agent as a histamine H2 antagonist in clinical studies for PD.
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).
The purpose of the study is to test whether body-worn wireless motion sensors can measure dyskinesias (involuntary movements caused by medications) in individuals with Parkinson disease (PD) independent of voluntary activity being performed and other PD motor symptoms (e.g. tremor).
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 purpose of the study is to investigate the anti-dyskinetic effect of several doses of sarizotan in Parkinson patients in order to generate information on the dose-response relationship (dose-finding).
