27 Clinical Trials for Various Conditions
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Up to approximately 670 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 study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Alzheimer's disease.
People under stress, such as those caring for an ill family member, often have trouble with their sleep. The aim of this study is to see if reducing stress and changing a caregiver's sleep and wake patterns will improve his/her sleep. The investigators also will see whether improvements in sleep result in improved mood, health, and general functioning.
In this study, researchers will learn more about a study drug called BIIB080. The study will focus on participants with mild cognitive impairment or mild dementia due to AD. The main question researchers are trying to answer is if BIIB080 can slow the worsening of AD more than placebo. It will focus on what dose of BIIB080 slows worsening of AD the most. To help answer this question, researchers will use the Clinical Dementia Rating-Sum of Boxes, also known as the CDR-SB. * Clinicians use the CDR-SB to measure several categories of dementia symptoms. * The results for each category are added together for a total score. Lower scores are better. Researchers will also learn more about the safety of BIIB080. The study will be split into 2 parts. The 1st part is the Placebo-Controlled Period. The 2nd part is the Long-Term Extension (LTE) Period. The 2nd part of the study will help researchers learn about the long-term safety of BIIB080, and how it affects the participant's daily life, thinking, and memory abilities in the longer term. A description of how the study will be done is given below. * After screening, participants will first receive either a low dose or high dose of BIIB080, or a placebo, as an injection into the fluid around the spinal cord (cerebrospinal fluid). A placebo looks like the study drug but contains no real medicine. * Participants will receive BIIB080 or placebo once every 12 weeks or 24 weeks. * After 76 weeks of treatment in the Placebo-Controlled Period, eligible participants will move onto the Extension Treatment period, which will last 96 weeks. * In the extension period, participants who received placebo will be switched to high dose BIIB080 every 12 or 24 weeks. * Participants may be in the study for up to 201 weeks, or about 4 years. This includes the screening and follow-up periods. * Participants can continue to take certain medications for AD. Participants must be on the same dose of medication for at least 8 weeks before the screening period. * After the screening period, most participants will visit the clinic every 6 weeks.
Alzheimer's disease (AD) is a progressive, irreversible neurological disorder and is the most common cause of dementia in the elderly population. Clinical symptoms of the disease may begin with occasional forgetfulness such as misplacement of items, forgetting important dates or events, and may progress to noticeable memory loss, increased confusion and agitation, and eventually, loss of independence and non-responsiveness. This study will assess how safe and effective ABBV-916 is in treating early AD. Adverse events, change in disease activity, and how ABBV-916 moves through body of participants will be assessed. ABBV-916 is an investigational drug being developed for the treatment of early AD. This study is conducted in 2 stages. Stage A is a multiple ascending dose study. There is a 1 in 4 chance that participants are assigned to receive placebo. Stage B is a proof-of-concept study. In Stage B, there is a 1 in 5 chance that participants will be assigned to receive placebo. The first 6 months of this study are "double-blind," which means that neither the trial participant nor the study doctors know which treatments will be given. This will be followed by a 2-year extension period in which all participants will receive ABBV-916. Approximately 195 participants aged 50-90 years will be enrolled in about 90 sites across the world. Participants will receive intravenous (IV) doses of ABBV-916 or placebo once every 4 weeks (Q4W) for 24 weeks and will be followed for an additional 16 weeks. Participants will have the option of participating in a 2-year, open-label, Extension Period receiving IV ABBV-916. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, magnetic resonance imaging (MRI), blood tests, checking for side effects and completing questionnaires.
A Randomized Pivotal Study of RenewTM NCP-5 for the Treatment of Mild Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type is a pivotal, single blind, parallel design, multi-site study intends to examine the efficacy and safety of RenewTM NCP-5 therapy in the treatment of Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type.

Alzheimer's disease (AD) is a progressive, irreversible neurological disorder and is the most common cause of dementia in the elderly population. Clinical symptoms of the disease may begin with occasional forgetfulness such as misplacement of items, forgetting important dates or events, and may progress to noticeable memory loss, increased confusion and agitation, and eventually, loss of independence and non-responsiveness. This study will assess how safe and effective ABBV-552 is in treating symptoms of early AD. Adverse events, change in disease activity, how ABBV-552 moves through body of participants and the body response to ABBV-552 will be assessed. ABBV-552 is an investigational drug being developed for the treatment of Alzheimer's disease (AD). Study doctors put the participants in 1 of 4 groups (3 active dose groups and a placebo group), called treatment arms. Each group receives a different treatment. There is a 1 in 4 chance that participants will be assigned to placebo. Approximately 240 participants aged 50-90 years with mild AD will be enrolled in approximately 60 sites across the world. Participants will receive oral ABBV-552 or placebo capsules once daily for 12 weeks and followed for 30 days after the last dose of study drug. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
This study will assess how safe ABBV-552 is and how ABBV-552 moves through the body of adult healthy Japanese and Han Chinese participants. Adverse Events will be assessed. ABBV-552 is an investigational drug being developed for potential treatment of Alzheimer's disease (AD). Approximately 18 adult healthy Japanese and Han Chinese volunteers will be enrolled in 2 sites in the United States. Japanese participants assigned to Arm 1 will receive ascending doses of ABBV-552 oral capsules once every week for 3 weeks. Han Chinese participants assigned to Arm 2 will receive oral ABBV-552 capsules on Day 1. All participants will be followed for 30 days after their last dose. Participants will be confined for 22 days or 8 days depending on the Arm they are assigned to. Adverse Events and blood tests will be performed.

Clinic visits will occur 4 weeks after the baseline visit, and then every 12 weeks until the end of the study. The safety of simufilam, and its efficacy in enhancing cognition and slowing cognitive and functional decline will be evaluated.
Background: In Alzheimer s disease (AD) the brain cannot use glucose as a fuel. The brain can use ketones as a fuel instead of glucose. Researchers want to test a supplement, Ketone Ester (KE). It may improve brain metabolic function and cognition in normal people and, perhaps, down the road, in patients with AD. Objective: To study the change in brain ketone levels in people after 28 days of taking KE compared with baseline and placebo. Also, to study changes in cognitive performance. Eligibility: People 55 years old or older with metabolic syndrome and no cognitive impairment Design: Participants will have 4 visits. Participants will be screened at Visit 1 with: Medical history Physical exam Blood and urine tests Cognitive testing Participants will be randomly assigned to receive either the study supplement or a placebo with same amount of calories. Neither they nor the researchers will know which they receive. Visit 2 will include repeats of some screening tests. It will also include: Stool sample (brought from home) MRI/MRS: Participants will lie on a table that slides in and out of a scanner. A coil will be placed over their head. They may be asked to perform leg exercises. First dose of study supplement or placebo About 2 weeks after Visit 2, Visit 3 will include blood and urine tests and a questionnaire. About 2 weeks after Visit 3, Visit 4 will include repeats of the Visit 2 tests. Participants will drink the study supplement or placebo 3 times per day during the study. They will keep a daily log of each dose. They will bring the log to Visits 3 and 4. Participants will by contacted by phone once per week during the study to see how they are doing.

This research will look at how the brain may change in people with Alzheimer disease (AD). The purpose of this research is to find out whether changes in the brain in people with Alzheimer disease can be detected using a brain imaging test. Most people with Alzheimer disease have changes in the brain that result in deposits of a protein called beta-amyloid. In this study, the investigators will be using a radioactive drug, \[18F\]MNI-558 that binds to beta-amyloid. This drug is experimental and has not been approved by the FDA. Brain imaging using PET (positron emission tomography) will be done to see if the investigators can evaluate the areas of beta-amyloid in the subjects with Alzheimer disease. The investigators will compare these scans with those done in healthy normal volunteers. PET is a brain-scanning test used in medicine and scientific research to see how the brain is working. The PET imaging test used in this study is not being done for diagnostic purposes.
The purpose of the study is to evaluate the efficacy and safety of MNI-513 positron emission tomography (PET) for detection/exclusion of cerebral amyloid beta in patients with Alzheimer's disease compared to healthy volunteers.
