Active clinical trials for "Parkinson Disease"

This pilot study will test Nilotinib's ability to alter the abnormal protein build up in Parkinson disease and Diffuse Lewey Body Disease patients . Patients will receive Nilotinib at different doses for 6 months. Patients will then be tested to see if there is change in three areas: 1) has the disease symptoms changed. 2) has levels of a specific misfolded protein changed in the fluid around their brain and spine. 3) Have inflammatory markers changed in the patient's blood and fluid around their brain and spine. If successful, this drug could be used to slow down or stop the progression of disorders that involve abnormal collection of misfolded proteins. However, the main purpose of this pilot study is to check for the safety of using this medication at this level.

Study to assess the safety, tolerability and effectiveness of a switching from Domin® (talipexole) tablet to BI Sifrol® (pramipexole) tablet in patients with Parkinson's disease

The investigators are observing the effects 2,000 mg of L-tyrosine will have on 24 hour blood pressure fluctuations in individuals with Parkinson's disease.

Background: Up to 70% of the patients with Parkinson's Disease (PD) experience speech problems, which cause a diminished intelligibility. A reduced intelligibility has a profound negative impact on social interaction and quality of life. Since pharmacological treatment only has limited effects on speech, non-pharmacological treatment, like speech therapy, is particularly relevant. Cochrane reviews (Herd et al., 2012a; Herd et al., 2012b) showed that evidence for speech therapy in PD is increasing, but is still inconclusive. Moreover, only very intensive standardized treatment programs have been studied, which are only feasible for people with mild to moderate PD, but too intensive for people with advanced PD. Here, the investigators will perform the first large-scale study to demonstrate the efficacy of speech therapy in PD patients in all disease stages on quality of life and speech quality. Objective: The aim is to demonstrate the effectiveness of personalized and home-based speech therapy on quality of life, intelligibility and social participation for people with Parkinson's disease who have a reduced intelligibility of speech. Methods: The investigators will perform a single blind, randomized and controlled trial. A total of 215 patients (18 years and older) with PD in all disease stages who have difficulty with intelligibility affecting daily communication will participate in this study. The patients will be randomly allocated to either speech therapy or a waiting list control group (1:1 ratio). Speech therapy using telerehabilitation will be provided for 8 weeks which consists of 12-16 sessions. The control group will receive deferred treatment after 8 weeks. The measurements will take place before the randomization (To), after 8 weeks (T1), and for the experimental group also after 24 weeks (T2). The primary outcome measure is quality of life, as measured using the total score on the PDQ-39. Secondary outcome measures include speech and voice, speech intelligibility, non-motor symptoms and caregiver burden. Hypothesis: The investigators hypothesize that patients in all disease stages can improve their speech intelligibility by using the explicit feedback from external cues provided by instructed caregivers plus a dedicated smartphone/ tablet app (the Voice Trainer app).

The effect of auricular stimulation on the locomotion capability in patients with Parkinson's Disease was investigated.

This study will evaluate the safety, tolerability, and potential effects on cognition of GRF6021, a plasma-derived product, administered as an intravenous (IV) infusion, to subjects with Parkinson's disease and cognitive impairment.

This is a randomized placebo-controlled, double-blind, parallel-group, enriched enrollment randomized withdrawal study assessing the efficacy and safety of nabilone for non-motor symptoms in patients with Parkinson´s Disease. Nabilone is an analogue of tetrahydrocannabinol (THC), the psychoactive component of cannabis. Nabilone acts as a partial agonist on both Cannabinoid 1 (CB1) and Cannabinoid 2 (CB2) receptor in humans and therefore mimics the effect of THC but with more predictable side effects and less euphoria. Part 1 is an open-label dose adjustment phase of the study. In eligible patients, a screening period is followed by an open-label nabilone dose optimization phase and a stable phase for at least 1 week. Treatment responders will be included in Part 2 of the study (randomized placebo-controlled, double-blind, parallel-grouped). Part 2 is the placebo-controlled, double-blind, parallel-group randomized withdrawal phase of the study.

The main objective of the MONANTI study is twofold: Firstly, to determine the amount of the anti-dementia drugs donepezil and memantine in the blood (henceforth mentioned as 'serum level) in a broadly defined clinical population of patients suffering from dementia treated with the two drugs in question. Secondly, to determine whether adjustment of treatment of anti-dementia medication according to serum levels will benefit patients in terms of cognitive performance, quality of life, frequency and severity of side effects. The reason for conduction of this study is that the relationship between serum-level of anti-dementia drugs, clinical efficacy, compliance and side effects has only been scarcely investigated. Both a previously published study and a preliminary (pilot)study conducted imply that roughly 50 % of patients on donepezil have serum-levels outside the recommended interval. Thus, MONANTI will investigate if this is indeed the case in a broadly comprised population of patients suffering from dementia treated with donepezil or memantine. In addition, MONANTI will link serum levels to co-morbidity, level of compliance, medication interactions. It is hypothesized that the efficacy of anti-dementia medication can be significantly improved by adjustment of treatment according to serum levels. Also, it is hypothesized that the burden of side effects can be reduced in patients in whom too high serum levels are detected, if dosage reduction or change of treatment drug is done. MONANTI is a randomized study, in which the assessor is blinded to avoid related biases to the extent possible. To fit the enrollment criteria a patient must be newly diagnosed with either Alzheimer's disease, dementia with Lewy-bodies or Parkinson's disease with dementia and be described treatment with either donepezil or memantine. Also, the patient must not meet a list of (exclusion) criteria, which have been set up in order to avoid blur and biases of the results. Patients can be selected as participators on account of the above, including an informed consent to participation. Next, the participators will randomized be assigned to one of two study arms. In the first of these, the control arm, the participators receive only standard treatment and follow-up at the outpatient clinic, except for measurement of serum level of the anti-dementia medication with which they are treated and a genetic test for a few key genes thought to be relevant for the study (two liver enzymes, two genes linked to Alzheimer's disease). In the other arm, the intervention arm, the participators will be closely monitored for side effects after prescription of anti-dementia drugs. All these participators will be offered a measurement of serum level in case they experience possible side effects within 2 months of treatment initiation. If, not a measurement of the serum level will be done after 6 months. All patients in the intervention arm, will be offered adjustment of their treatment with the anti-dementia drug based upon serum level. To assess the possible effects of treatment adjustment seven clinical scoring tests will be used (MMSE, ACE, clock-drawing test, NPI-Q, DAD, GCI, GDS). Assessment includes symptom severity and level of compliance according to close relatives. To measure the effect of donepezil on brain (cholinergic) function 30 participants will be recruited for electroencephalography (EEG). These participants will have an EEG done at enrollment and after 6 months. In addition to the quantitative part study a qualitative part study with relatives of enrolled patients will be conducted. All the needed approvals have been obtained according to Danish law (approval by the Danish Data Protection Agency, Scientific Ethics Committee for Region Sjaelland, The Danish Medical Agencies).
