Active clinical trials for "Lewy Body Disease"

Brain oscillations are ubiquitous in the human brain and have been implicated in cognitive and behavioral states defined in precisely tuned neural networks. In neurodegenerative disorders, neurodegeneration is accompanied by changes in oscillatory activity leading to the emerging concept of neurological and psychiatric disorders as "oscillopathies". Dementia with Lewy bodies (DLB), which is the second most frequent cause of neurodegenerative dementia, is characterized by an important alteration of brain oscillations. The restoration of oscillations by neuronal entrainment in animal models of neurodegenerative disease has shown a significant reduction in the neuropathological load of toxic proteins, with a consequent significant increase in cognitive performance. Transcranial alternating current brain stimulation (tACS), is a neurophysiological method of non-invasive modulation of the excitability of the central nervous system that is having an increasingly numerous spectrum of potential therapeutic applications. Recent studies have demonstrated the effectiveness of this method in modulating the natural frequencies of cerebral oscillation, underlying multiple cognitive processes such as verbal memory, perception and working memory. On the basis of these premises, the treatment with alpha tACS is proposed in patients with DLB. In this randomized, double-blind, sham-controlled, cross-over study, the investigators will evaluate whether a single stimulation with alpha tACS on the occipital lobes can improve symptoms in patients with DLB.

TOPHAT (Trial of Ondansetron as a Parkinson's HAllucinations Treatment) is a double blind, individually randomized, placebo-controlled, parallel group, flexible dose trial of ondansetron (8-24mg/day) as a treatment for Parkinson's hallucinations, with a 12-week primary outcome and follow-up to 24 weeks.

This is a confirmatory investigational medicinal product (IMP) study to investigate the effects on cognition, functional decline and on neuropsychiatric symptoms of the Glucocerebrosidase (GCase) enhancing chaperone ambroxol in participants diagnosed with prodromal and early dementia with Lewybodies (DLB).

The purpose of this study is to learn more about the effectiveness of palliative care training for community physicians and telemedicine support services for patients and carepartners with Parkinson's disease and Lewy Body Dementia (LBD) or related conditions and their care partners. Palliative care is a treatment approach focused on improving quality of life by relieving suffering in the areas of physical symptoms such as pain, psychiatric symptoms such as depression, psychosocial issues and spiritual needs. Telemedicine is the use of technology that allows participants to interact with a health care provider without being physically near the provider.

Multi-center, randomized, double-blind, placebo-controlled, 6- month study in subjects with mild to moderate Dementia with Lewy Bodies.

The present study is a monocentric, therapeutic clinical trial involving forty patients diagnosed with Dementia with Lewy Bodies (DLB). The aim of this clinical trial is to evaluate the feasibility and relevance of repetitive transcranial magnetic stimulation (rTMS); a non-invasive neuromodulation technique, with a main emphasis on the evaluation of the outcome on cognitive fluctuations. For this purpose, we will compare two distinct rTMS conditions (control and experimental) in a pre-post rTMS setting. The experimental condition will be targeting the insular cortex which has been shown to be affected at prodromal DLB stages, in the form of decreased grey matter concentration and a decreased regional Cerebral Blood Flow (rCBF hypoperfusion) [Blanc et al., 2015 ; Roquet et al., 2016 ; Roquet et al., 2017]. Furthermore, these insular alterations are correlated to cognitive fluctuations [Chabran et al., 2020]. In DLB, cognitive fluctuations are particularly pervasive and manifest in the form of alertness alterations and modifications of arousal states. Participants will repeatedly undergo a series of clinical and cognitive assessments in addition to several neuroimaging examinations, namely multimodal Magnetic Resonance Imaging (MRI) and electroencephalogram (EEG) recordings, in order to evaluate potential physiological modifications and clinical changes of symptoms, pre-/post-rTMS.

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/

This study evaluates the safety and tolerability of treatment with K0706 in Dementia with Lewy Bodies (DLB). The hypothesis is that K0706 will be safe and tolerable and that this drug will alter CSF and plasma biomarkers in DLB. Clinical assessments of cognitive, behavioral and motor functioning will also be evaluated. A total of 45 participants will be randomized 1:1:1 into 3 groups (n=15/per group) to be treated with sachet of 192 mg powder of K0706 ( equivalent to 96 mg capsule of K0706) or sachet of 384 mg powder of K0706 (equivalent to 192 capsule of K0706) or sachet of matching placebo ( equivalent to a capsule of placebo) for 12 weeks, followed by 4-week wash-out period.

Dementia with Lewy Bodies (DLB) is an alphasynucleinopathy and the second most common form of dementia in the elderly. DLB shares striking neuropathological and clinical similarities with both Parkinson's disease (PD) and Alzheimer's disease (AD). Nilotinib (Tasigna®, AMN107, Novartis, Switzerland) is approved by the FDA and is well tolerated for CML treatment at oral doses of 600-800mg daily. The Investigators propose to perform a phase II randomized, double blinded, placebo controlled study to evaluate the impact of Nilotinib in patients with DLB.

This home-based study is a randomized (1:1) placebo-controlled trial of a single infusion of zoledronic acid-5 mg (ZA) for the prevention of fractures in men and women aged 60 years and older with Parkinson's disease and parkinsonism with at least 2 years of follow-up. A total of 3500 participants will be enrolled and randomized in the United States. Participants, follow-up outcome assessors, and study investigators will be blinded to assigned study treatment. This trial is funded by the National Institute of Aging.
