Active clinical trials for "Alzheimer Disease"

The goal of this clinical study is to learn about an investigational gene therapy product called AVB-101, which is designed to treat a disease called Frontotemporal Dementia with Progranulin Mutations (FTD-GRN). FTD-GRN is an early-onset form of dementia, a progressive brain disorder that affects behavior, language and movement. These symptoms result from below normal levels of a protein called progranulin (PGRN) in the brain, which leads to the death of nerve cells (neurons), affecting the brain's ability to function. The main questions that the study aims to answer are: Is a one-time treatment with AVB-101 safe for patients with FTD-GRN? Does a one-time treatment with AVB-101 restore PGRN levels to at least normal levels? Could AVB-101 work as a treatment to slow down or stop progression of FTD-GRN? In this study there is no placebo (a dummy pill or treatment used for comparison purposes), so all participants will receive a one-time treatment of AVB-101 delivered directly to the brain, with follow-up assessments for 5 years.

This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).

This single-center, double-blind, placebo-controlled study will recruit in total 39 participants with either Mild Cognitive Impairment due to Alzheimer's disease (MCI) or Mild Alzheimer's disease dementia (mild AD). There will be 3 Dose levels. An initial cohort of 13 subjects will be randomized to a Dose level 1 (0.1 mg/kg vs. placebo) lasting 8 weeks. An additional 13 subjects will be recruited and randomized into Dose level 2 (0.25 mg/kg vs. placebo) for 8 weeks and 13 subjects for the last Dose level 3 (0.5 mg/kg vs. placebo) for 8 weeks. The primary objective will be to assess safety and tolerability of CpG 1018.

Approximately 90 patients, aged 50 to 80 years, with a diagnosis of early Alzheimer's disease will take part in this research study. This study will be conducted in the US. There will be 3 treatment groups: 2 Active doses and 1 group will receive placebo completely by chance. Patients, caregiver, Sponsor, nor study staff will know which treatment is assigned. There are 3 periods in this study: Screening to confirm suitability, Treatment to receive study medication, and Follow-up to check overall health post-participation

The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of MK-2214 in adults with mild cognitive impairment (MCI) or mild-to-moderate Alzheimer's Disease (AD). The primary hypothesis (Part 1) is that at a generally well tolerated dose level, the true geometric mean concentration at Day 85 of MK-2214 in cerebrospinal fluid is >0.3 nanomolar (nM). Optional healthy older participants (Part 2) may receive MK-2214 at dose levels determined by criteria met in Part 1.

The primary objective of this study is to verify the clinical benefit of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score as compared with placebo in participants with early Alzheimer's disease.

Recent findings suggest that sleep disruption may contribute to the generation and maintenance of neuropsychiatric symptoms including anxiety, depression, agitation, irritation, and apathy while treating sleep disruption reduces these symptoms. Impairments in the neural systems that support emotion regulation may represent one causal mechanism mediating the relationship between sleep and emotional distress. However, this model has not yet been formally tested within a sample of individuals with or at risk for developing Alzheimer's Disease (AD) This proposal aims to test a mechanistic model in which sleep disturbance contributes to neuropsychiatric symptoms through impairments in fronto-limbic emotion regulation function in a sample of individuals at risk for developing, or at an early stage of AD. This study seeks to delineate the causal association between sleep disruption, fronto-limbic emotion regulation brain function, and neuropsychiatric symptoms. These aims will be achieved through a mechanistic, randomized 2-arm controlled trial design. 150 adults experiencing sleep disturbances and who also have cognitive impairment with the presence of at least mild neuropsychiatric symptoms will be randomized to receive either a sleep manipulation (Cognitive Behavioral Therapy for Insomnia CBT-I; n=75) or an active control (n=75). CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Neuropsychiatric symptoms, fronto-limbic functioning, and sleep disruption will be assessed at baseline and at the end of the sleep manipulation through functional Magnetic Resonance Imaging (fMRI), clinical interviews, PSG recordings, and self-report questionnaires. Neuropsychiatric symptoms (anxiety and depression) and sleep disturbance (actigraphy, Insomnia Severity Index, and sleep diaries) will be assayed at baseline and each week throughout the sleep manipulation to assess week-to-week changes following an increasing number of CBT-I sessions. Wristwatch actigraphy will be acquired from baseline to the end of the sleep manipulation at week 11. Neuropsychiatric symptoms and sleep will be assessed again at six months post-manipulation.

Donepezil, as well as the other symptomatic drugs of Alzheimer's disease, is not any more reimbursed by the French healthcare system, due to a controversy about its efficiency. French health authorities currently preconize a non-rug approach based on cognitive remediation or stimulation. The aim of this study is to compare the efficiency of the 2 approaches (non-drug versus donepezil) on the symptoms of Alzheimer's disease after 6 months of treatment.

Study will be conducted to determine if caregivers who use music at home will feel less burden and whether the person they are caring for will demonstrate decreased symptoms of dementia. Caregivers will participate in a series of psycho-educational trainings for six weeks. During this time, caregivers will learn how to use singing, music listening and music with movement with their family member. Caregivers should feel less stressed and a decreased sense of burden. The care recipient should appear happier with less occurrences of depression or restlessness.

This study compares different music therapy (MT) experiences and their impact on memory and language in patients with Alzheimer's disease and Mild Cognitive Impairment. The 12-month study will assess the role of common experiences involving familiar music and other pleasant events (blinded control) to benefit cognition and measure the quality of life for people with Alzheimer's disease and Mild Cognitive Impairment. Following screening, all participants will meet with a licensed music therapist at the first study visit. Thereafter, each group will have an individualized schedule of follow-up telephone calls and visits. Screening for the study and participation in the study intervention can be completed in-person or from your home, if you do not live in the area.
