Active clinical trials for "Parkinson Disease"

This is a double blind placebo controlled trial in Parkinson's disease (PD) patients with neurogenic orthostatic hypotension (NOH). Investigators hypothesize that the study drug (droxidopa) may improve cerebral perfusion more robustly than systemic BP, possibly by direct action within the CNS vasculature. This study is designed to determine if droxidopa improves cerebral perfusion measures in PD patients with NOH, in addition to peripheral BP measures and subjective responses.

Due to Parkinson's Disease (PD) speech and language (SL) deficits may occur. Further, the literature reports that PD patients, who have not undergone deep brain stimulation (DBS), have deficits regarding voice quality (e.g. loudness and intelligibility of their voice), while PD patients who have undergone DBS suffer from deficits in word retrieval and speech apraxia symptoms. To-date, therapeutic approaches focusing specifically on SL deficits observed in PD-DBS patients are yet to be developed and evaluated. Therefore, this study investigates the short-and longterm effectiveness of specific and intensive, high-frequency speech-language therapy in terms of reducing SL-deficits compared to a nonspecific and non-verbal sham treatment (i.e. a rhythmic balance-movement training (rBMT)) as well as to a 'no-therapy' condition.

The purpose of this study is to demonstrate that young plasma infusions can be performed safely in patients with Parkinson's Disease (PD). Secondary outcomes will include behavioral and laboratory data that will support the next study that will inquire whether young plasma infusions improve or slow the progression of cognitive, mood and/or motor impairment and rate markers of the disease.

This is a two-center (University of Colorado, University of California San Francisco) community-based comparative effectiveness study of outpatient palliative care for Parkinson's disease (PD) and related disorders (progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), multiple systems atrophy (MSA), Lewy Body Dementia (LBD). In September 2018, the study was amended to also include Alzheimer's disease (AD) and related disorders (Frontotemporal Dementia (FTD), Primary Progressive Aphasia (PPA), Vascular Dementia). It will utilize a randomized stepped-wedge design to compare patient and caregiver outcomes between usual care in the community versus usual care augmented by palliative training and telemedicine support to provide other resources (e.g. social work).

The purpose of this study is to investigate the effect of food on the catechol-O-Methyltransferase (COMT) activity after repeated doses of opicapone (OPC, development code BIA 9-1067) in healthy subjects and to characterize the effects of food on the pharmacokinetics (PK) and tolerability of OPC after repeated doses.

In low-income areas worldwide, most patients with Parkinson's disease (PD) cannot afford long-term Levodopa therapy. A potential therapeutic option for them is the use of a legume called Mucuna Pruriens var. Utilis (MP), which has seeds with a high levodopa content (5-6%) and grows in all tropical areas of the world. MP powder is very cheap (total annual cost for a PD patient: 10-15 US $). The aim of this study is to assess efficacy and tolerability of acute and chronic use of MP compared to standard Levodopa therapy. The primary objective of this study is to investigate efficacy of acute levodopa challenge using MP in comparison to levodopa with a Dopa Decarboxylase Inhibitor (LD+DDCI) and without (LD-DDCI) and placebo. The secondary objectives are to investigate safety of acute intake of MP as well as efficacy and safety of chronic intake of MP over a 8-week period in comparison to usual LD+DDCI home therapy.

The purpose of this study is to improve outcomes for persons living with Parkinson's Disease (PD) and their family caregivers. The investigators hypothesize that outpatient interdisciplinary palliative care will improve patient-centered outcomes for PD patients at high-risk for poor outcomes.

This is the first study on the effect of the variable frequency stimulation (VFS) on Freezing of gait (FOG) in Parkinson's disease (PD) patients with STN DBS. FOG has responded poorly to High frequency stimulation (HFS) but can be alleviated by relatively VFS. This study would have significant clinical implications in the management of Freezing of gait (FOG) in these PD patients with subthalamic nucleus (STN) DBS. The investigators hypothesize that VFS could have better effect on FOG than HFS and low frequency stimulation (LFS).

The purpose of this study is to evaluate safety and effectiveness of the peripheral mechanical stimulation of the feet on gait variables, clinical status, risk of falls, BDNF levels, immunological profile and brain functional connectivity changes in patients with Parkinson's disease.

This is a follow-up study to assess safety and clinical activity of continued AFFITOPE® PD01A vaccinations in patients with Parkinson's disease. Patients, who have already participated in the AFF008 program will be involved and will receive a second boost immunization with AFFITOPE® PD01A. One study site in Vienna (Austria) will be involved. In addition, up to 6 patients will be offered participation within an untreated control Group.
