Filter by:Approximately twenty four (24) subjects will participate in this research trial. The research trial will be conducted in approximately twelve (12) medical centers in the following countries: Germany, France, South Africa, Austria and Canada. The research trial will last until December 2011.
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 responsiveness of a variety of available dyskinesia rating scales to treatment with amantadine or placebo in Parkinson's disease patients with dyskinesia. The study will be a parallel, double-blind, randomized trial of 68 patients treated with amantadine or placebo for 8 weeks. Pre-treatment evaluations will be performed and compared to end of study evaluations on the best treatment dose (200 or 300 mg amantadine or matching placebo) daily. Safety evaluations will be conducted. The responsiveness of the different scales will be evaluated statistically with a mixed model in which changes in the outcome measures over time will include a fixed effect of treatment group assignment. The model will additionally account for random effects of intercepts (the scale scores at baseline) that will include both random variation (person-specific) and specific variation associated with rate of change in outcome. The investigators may include adjustments for possible confounding covariates, including baseline demographics and center. The goal of the program is to provide researchers with the best scale(s) to distinguish dyskinesia change in Parkinson's disease (PD) associated with amantadine in comparison to placebo and to establish the magnitude of effect achievable with amantadine as a comparator "gold standard" that must be met or surpassed by future anti-dyskinetic agents. Additionally, with the use of paper and pencil questionnaires, the study will investigate the impact of patient optimism and patient and rater expectation of positive effects on the dyskinesia rating outcomes.
This phase IIb study is designed to determine the safe and efficacious dose or dose range of AFQ056 for the treatment of patients with moderate to severe Parkinson's disease with L-Dopa induced dyskinesias.
Natural Orifice Translumenal Endoscopic Surgery (NOTES) describes a new field of investigational surgery which uses the endoscope as the primary operative tool. The insertion sites for the endoscope include natural orifices such as the mouth, anus, vagina, or urethra. Multidisciplinary teams of surgeons and gastroenterologists collaborate to develop safe and effective surgical techniques via the natural orifice route in order to avoid surgical incisions. Early studies have focused on transvaginal surgery as the access route to the abdomen as it sidesteps troubling questions about infection and closure of the organ. This study is a pilot study to test the feasibility to NOTES transvaginal cholecystectomy using conventional surgical and endoscopic tools.
Prospective randomized trial of single incision versus standard 4 port laparoscopic cholecystectomy. Hypothesis is that the operative time will be longer with single incision.
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?
Previous researchers indicate that impaired cognitive flexibility was the primary factor distinguishing patients with from those without tardive dyskinesia (TD)1, and cognitive dysfunction correlates positively with the severity of TD2. Longitudinal data raised the possibility that the association between cognitive dysfunction and TD may reflect not organic vulnerability to but rather a state marker for this movement disorder as "tardive dementia"3. Atypical antipsychotic had been reported to alleviate the severity of TD4 and improved neurocognitive function separately5. But no researchers ever investigated the correlation of the two effects simultaneously. This randomized, single-blind and controlled study compared the effect of atypical antipsychotic on TD, neurocognitive function and associated factors for these changes.
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 purpose of this study is to study different kinds of dyskinesias in advanced Parkinson's disease appearing at different levels of levodopa infusion dose. The hypothesis is that different dyskinesias (dystonia, chorea) correlate to different levels of levodopa concentrations, as detected in plasma.
