Filter by:The purpose of this study is to determine the safety and efficacy of TRx0237 16 mg/day and 8 mg/day in the treatment of subjects with Alzheimer's Disease compared to placebo. In addition, an open-label, delayed-start phase is included to demonstrate a disease-modifying effect of TRx0237.
Of the 1.4 million nursing home (NH) residents in long term care facilities, more than half have Alzheimer's disease or dementia. Due to changes in their familiar daily routines, difficulty expressing their thoughts or asking for what they need, and overstimulation (such as noise) or under stimulation (such as lack of activity), individuals with dementia often display disruptive behaviors like resisting help or continually repeating the same phrases. Medications are often prescribed to reduce agitation and aggressive behavior; however, these medications may not be effective and can have a negative impact on the individual. Therefore, families and other stakeholders strongly advocate the use of other types of approaches that focus on minimizing the cause of the behavior. Two facility-based methodologies include the transdisciplinary approach for integrated dementia care, which combines the expertise of all NH staff, who work together to build a common language and approach for each resident, and the multidisciplinary approach for problem-based dementia care, in which each staff member conducts individual assessments and makes discipline-specific recommendations. While prior research suggests that both of these facility-based approaches are useful, the circumstances under which each approach is most effective are not clear. This project will prospectively randomize 80 nursing homes to one of the two treatment arms to compare the effect of the transdisciplinary approach versus the multidisciplinary approach. This study will examine the difference between the two comparators with respect to facility rates of medications dispensed to residents with dementia, leading to enhanced quality of life for the resident. This project is important because it will address a key clinical dilemma NH staff face as they strive to optimize the use of alternative approaches to reduce disruptive behaviors in residents with dementia. Transforming the quality of dementia care in NHs and enhancing the quality of life of residents with dementia are high priorities for families and other advocates.
A study to assess the effect of heat application on the delivery profile of Corplex™ Donepezil Transdermal Delivery System (TDS)
For this project, neflamapimod and placebo will be provided free of charge by the EIP company (www.eippharma.com). Neflamapimod is currently tested in 2 clinical trials in AD, one in Europe (The Netherlands) and one in the USA (clinical trials.gov/VX-745). The company commenced in May 2015 dosing in two phase 2a clinical studies in patients with Early AD: one in the Netherlands that is focused on PET amyloid imaging as the primary biomarker of drug effect, and one in the US (California) that is focused on Cerebrospinal fluid (CSF) evaluation to determine CSF drug concentrations and effects on inflammatory markers and disease biomarkers. Pharmacokinetic evaluation in these patients has demonstrated blood drug concentration levels in the predicted therapeutic range; and importantly, the data from the US study demonstrate that the drug achieves target drug concentrations in CSF, thus confirming the drug robustly enters the brain in humans. The present project offers us a unique chance to test this promising drug in AD patients. The aim of the study is to focus on PET neuroinflammation imaging as the primary biomarker of this drug effect. The chosen biomarker for imaging neuroinflammation in patients is [1 8F]-DPA714.
France put a massive effort for improving dementia care through a national Alzheimer plan in 2008 and this effort was confirmed by the next government (Neurodegenerative Diseases Plan 2014-2019). Some new care models and interventions have been implemented such as Alzheimer specialized teams offering occupational therapy. The teams intervene at home with medical prescription. A recent pilot study demonstrated that occupational therapy has the potential to bring clinical benefits for both dementia patients and their caregivers. Nevertheless, occupational therapy has been designed as a short-term intervention and the end of intervention is challenging for therapists and patients. We aim to test the clinical and economic efficacy of maintaining occupational therapy over supplementary 4 months in a pragmatic randomized controlled trial.
A Phase 1, Crossover Study to Evaluate the Pharmacokinetics of Corplex™ Donepezil 10 mg Transdermal Delivery System Applied to Different Body Locations
This project will provide new data to address an important question linking Alzheimer's disease neuropathology to physical disability.
One major study objective is, using 2 study arms (data-driven health coaching plus RC vs. RC only), to evaluate the efficacy of data-driven health coaching. 'RC only' will serve as the control group. Participants will be enrolled in the trial on the basis of an existence of objective cognitive impairment defined by the MCI Screen (MCIS) and being in one of three functional stages as defined by the Functional Assessment Staging Test (FAST). The three FAST stages correspond to cognitive impairment without functional impairment (FAST 2), cognitive impairment with functional impairment without impairment in instrumental activities of daily living (FAST 3, also known as mild cognitive impairment, MCI), or cognitive impairment with impaired instrumental activities of daily living (FAST 4). Study objectives include measuring treatment related changes in cognitive and functional abilities, quality of life, and biological or biochemical measures. A second major study objective is to analyze longitudinal multi-omic data from individuals on a trajectory of early-stage dementia, to discover correlations between measured variables, and identify models of causation that can further advance knowledge and research in brain degeneration and healthy living
This pilot study aims to test clinical and connectivity changes following non-invasive stimulation of disease-specific networks in Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD). Brain network stimulation will be carried out with transcranial direct current stimulation (tDCS). Target networks will be the default mode network (DMN) and salience network (SN). Twenty AD and 20 bvFTD patients will be recruited and assessed with a comprehensive clinical, behavioral and cognitive battery, and 3 Tesla MRI scan (including resting-state functional MRI, arterial spin labeling, diffusion tensor imaging, structural MRI) at three time-points: baseline, after tDCS, and after 6 months. Patients will be randomized to 2 arms: anodal stimulation of the disease-specific network (DMN in AD, SN in bvFTD) or cathodal stimulation of the anti-correlated network (SN in AD, DMN in bvFTD). The intervention will consist of 10 tDCS sessions over two weeks. Cerebrospinal fluid (CSF) samples will be collected at baseline for biomarker's assessment; blood samples will be collected at each time-point to assess changes in peripheral inflammatory markers. Blood and CSF collection will be optional. A sample of 20 elderly controls will be included for baseline comparisons.
This research project concerns the evaluation of the Metabolic Hyperspectral Retinal Camera (MHRC), a novel medical instrument from Optina Diagnostics, for the detection of beta-amyloid plaques, a hallmark of Alzheimer's disease (AD), in the retina. The experimental device, produces multiple images of the retina when subjected to light in very specific colors (90-100 specific colors typically) and may be used to identify specific biomarkers based on their unique spectral signature. The retina is an extension of the brain and is the only optically accessible nervous tissue. The MHRC could represent a simple and non-invasive tool to facilitate the diagnosis of AD.
