Filter by:An open-label randomized study to evaluate the Safety, Tolerability, and PK of Low and High single doses of ND0612 (i.e. LD/CD ratio 60/7.5 mg/mL and 60/14 mg/mL), as well as the combination with oral Entacapone (concomitant catechol-O-methyl transferase [COMT] inhibitor) in PD subjects with well-defined morning "OFF" and a good response to LD. Exploratory efficacy parameters were collected (early evidence of effectiveness as part of Phase 1).
This single ascending dose study is to determine safety, tolerability, pharmacokinetics and immunogenicity of PRX002 in approximately 40 healthy subjects.
The purpose of this study is to see if the study drug, Mirabegron, is safe and effective in treating symptoms of Overactive Bladder in people with Parkinson's Disease.
The purpose of this study is to determine the effects of age on the pharmacokinetic (PK) profile of BIA 9-1067 and its metabolites.
The objective of this study is to investigate the efficacy and safety of two different dose levels of NT 201 (75 U or 100 U per cycle), compared with placebo, in reducing the salivary flow rate, and the severity and frequency of chronic troublesome sialorrhea that occurs as a result of various neurological conditions in adult subjects.
This is an extension study to evaluate the long-term safety and tolerability of ABT-SLV187 in subjects with advanced Parkinson's disease.
Changes in deep brain stimulation (DBS) settings can have a delayed effect on gait function, which makes it impractical to optimize DBS for gait parameters in the clinic. Wearable movement sensors could be used to assess gait impairment in the patient's home hours after treatment adjustments are made in the clinic. This study aims to quantitatively evaluate the effects of turning off deep brain stimulation on lower extremity and gait function over three hours. This study will provide vital information about our patient worn system's ability to detect changes in lower impairment over time, which could be used to assist with DBS tuning for the lower extremities and gait in the future.
Mild cognitive impairment and dementia are frequent non-motor complications of moderate to advanced Parkinson's disease. Brain positron emission tomography (PET) study findings confirm post-mortem evidence that cholinergic loss is related to cognitive impairment in Parkinson's disease. However, current cholinergic augmentation therapy is not always effective and it should only target those Parkinson's disease patients who have evidence of cholinergic system impairment. The objective of this study is to study the association of a particular subtype of cholinergic receptors, so-called nicotinic acetylcholine receptors, with cognition in Parkinson's disease using a novel PET marker of cholinergic system integrity.
This study is implemented to identify factors having an impact on improvement or exacerbation of non-motor symptoms, to provide information contributing to development of medical care in this field and improvement of patients' QOL, and to clarify the association between the use of istradefylline and non-motor symptoms or QOL.
Parkinson's disease, a degenerative disorder of the dopaminergic system, combines motor symptoms but also non-motor, such as depression, sleep disorders and circadian rhythms and impaired cognitive functions. Difficulties in balancing the dopaminergic treatment of these patients emphasizes the need to find effective adjuvant therapies. Light therapy (LT) represents one such innovative therapeutic approach. Although light has an obvious to visual pathways within the brain, today it is known to additionally exert non-visual effects throughout the body. Recently our team has shown that non-visual, non-circadian light plays a major role in the regulation of sleep, as well as cognitive brain function in general. The retina, the primary conduit for the transmission of light information is weakened or thinned in Parkinson's patients. The dopamine system is known to enhance the processing of light information and intraocular injection of L-dopa in animal models of Parkinson's disease, can reverse associated motor symptoms. This allows for the possibility that LT would strengthen the dopaminergic tone in the central nervous system. However, to this date its effectiveness for alleviating Parkinson's symptoms has only been suggested by two studies, both poorly controlled. Thus, through the convergence of basic and clinical data, a study examining the effect of LT directly in people Parkinson's disease symptoms, whilst controlling for the effects on sleep, circadian system, mood, and cognitive functioning, is of extreme importance. With this information our hope is to determine if these polymorphisms allow for a predictive model of response to LT treatment.
