Filter by:A long-term follow-up study to obtain safety and efficacy data in subjects who completed phase 1/2a clinical trial of NEUROSTEM® (NCT02054208), comparing NEUROSTEM and placebo groups for up to 36 months after the initial administration in patients suffering from Alzheimer's disease
A recent study (Saltmarche et al., 21017) examined the effects of photobiomodulation (PBM), a kind of light therapy that uses red or near-infrared light to heal and protect tissue that has either been injured, is degenerating, or else is at risk of dying, in 5 older adults with dementia. After 12 weeks of PBM treatments, delivered with a commercially available, wearable device, the patients with mild to moderately severe dementia showed improvements on the Mini-mental State Exam (MMSE, p<0.003) and Alzheimer's Disease Assessment Scale-cognitive, ADAS-cog, p<0.03). The caregivers, who kept daily journals of their experiences during the 12 weeks of PBM treatment, reported better sleep, fewer angry outbursts, decreased anxiety and wandering in their loved-ones with dementia. The goals of this trial are to: (1) replicate this finding in a larger group of individuals with dementia and (2) to examine the underling brain mechanisms behind the changes in cognitive function.
850,000 people live with dementia in the UK, with that number expected to rise to more than 1 million within the next 5 years. The most common type of dementia (55%) is Alzheimer's dementia, and vascular dementia is the second commonest type (15%). Mild cognitive impairment (MCI) affects up to 20% of older adults and describes a set of symptoms rather than a specific medical condition or disease. A person with MCI has subtle problems with one or more of the following: day-to-day memory, concentrating, planning or organising, language (eg struggling to find the right word), and judging distances and seeing objects properly. Although MCI significantly increases the risk of developing dementia (by up to 5 times), at present it is not possible to accurately predict which patients with MCI will progress to dementia. In recent times there has been an increasing awareness that problems with brain blood flow may contribute to the development, or progression, of dementia. Tests of mental abilities, with standardised questions and pen-and-paper tests are a key component of the formal diagnosis of dementia, yet little is known of the effects of these tests on brain blood flow. Brain blood flow can be can be assessed non-invasively by the use of Trans Cranial Doppler (TCD). This means using ultrasound probes over both sides of the head to measure changes in blood flow in one of the main brain arteries (the middle cerebral artery). This proposed study will therefore use TCD to evaluate changes in brain blood flow during performance of the Addenbrooke's-III (ACE-III) cognitive assessment in four key groups of patients, specifically: 1. Healthy older adults 2. Patients with mild cognitive impairment (MCI) 3. Patients with vascular dementia 4. Patients with Alzheimer's dementia
The study goal is to evaluate user experience with our developed exergame, which was designed to increase physical activity, exercise self-efficacy, and social connections among caregivers of individuals with Alzheimer's disease (AD) or related dementias. Participants will use this garden-themed exergame for six weeks. Tailoring an exergame for caregivers of AD or related dementias has the potential to increase physical activity and to improve overall health and well-being in this vulnerable population, which in turn can benefit the patients for whom they provide care. All study sessions be held at a location convenient to participants.
The goal of the study is to learn about how possible benefits of movement and music for individuals with dementia. Individuals with dementia will participate in a dance class. The study includes assessments of walking, balance and cognition.
In Alzheimer's disease (AD) an imbalance between the production and clearance of the ß-amyloid peptide is hypothesized as the driving event of the disease. The decreased clearance of Aß could be partly linked to a progressive dysfunction of the brain vasculature and of the blood brain barrier (BBB). Among many possible explanations for these failures of the multiple clinical trials evaluating innovative drugs in AD, one is the lack of target engagement, as none of these drugs is able to readily cross BBB. This barrier acts as a wall that actively and passively prevents the crossing of molecules between the blood and the brain parenchyma compartments. Only 0.3% of intravenously injected anti-Aß immunoglobulins reach the brain despite a half-life of 15-20 days. Low intensity Focal ultrasound associated to microbubble injection can open the BBB in a non invasive way. These openings are reversible in 2 hours to 2 days depending on the intensity of the ultrasound. Ultrasound opening of the BBB was initially used in a transgenic mouse model of AD to increase the brain delivery of an anti-Aß antibody. In this article, the Aß load was reduced in ultrasound treated brain region. Surprisingly it was then demonstrated that the simple opening of the BBB without any adjunct anti-Aß treatment was able to drive the same Aß clearance effects. This is probably linked to endogenous antibodies that are able to penetrate the brain parenchyma and target Aß plaques. Four opening sessions elicited positive promnesic effects in these mice. Our group conceived and developed a mean to easily, reproductively and innocuously open the BBB. A unique extra-dural ultrasound emitter (sonoCloud®) is surgically implanted in the skull under local anesthesia. It emits low intensity contact ultrasound (LICU) that are not deterred by bone and thus are able to open the BBB.Preclinical studies show the SonoCloud® device is safe and efficient as it allowed reproducible and repeatable opening of the BBB in rabbits, dogs and non human primates. Drugs up to 2000 Kilo Daltons (kDa) are able to cross the BBB to reach the brain parenchyma in which the concentration of Carboplatin was increased by 700% in the BBB opened region. No adverse event was evidenced both clinically, by EEG, Evoked potential, MRI, 18 Fluorodeoxyglucose (FDG) PET and histology in the primates after 7 bi-monthly sessions of LICU BBB opening. SonoCloud® and its external generator have been certified by the academic start-up CarThéra (APHP, UPMC). Our multidisciplinary skills (neurology, neurosurgery, neuroimaging, basic science departments in the same University hospital setting) and our previous experience of BBB opening in Man give us the unique opportunity to translate this procedure from neuro-oncology to AD which could 1) Have a positive effect on brain lesion load and symptoms by itself and 2) allow anti-AD (or more broadly, central nervous system) drugs to engage their targe
The specific aims of this study are 1) to test the trial and intervention feasibility of Brain Care Notes (BCN) app, 2) To estimate the effect size of BCN on reducing informal caregiver burden at 6 months, and 3) To estimate the effect size of BCN on reducing patient behavioral and psychological symptoms of dementia (BPSD) at 6 months. Subjects will be recruited from the Aging Brain Care (ABC) program of Eskenazi Health and Indiana University Health located in central Indiana.
To evaluate the safety and tolerability of pimavanserin over 52 weeks of treatment in subjects with probable AD who have symptoms of agitation and aggression
This is a randomized, double-blind, placebo-controlled, parallel-group comparison study in subjects with Alzheimer's Disease. Following first screening period, subjects will be randomly assigned into one of the following arms: AstroStem and placebo control in a 1:1 ratio. AstroStem or placebo control will be administered via I.V. at Week 0. This procedure will be repeated 9 times at 2-week interval. Subjects will be scheduled for two follow-up visits at Weeks 30 and 52 to evaluate primary and secondary outcome endpoints.
This first time study in humans was designed to assess tolerability and safety of repeated subcutaneous injections of ABvac40, an active immunization against the C-terminal end of Abeta1-40.
