Dementia Paid Clinical Trials in California

This study will investigate different donanemab dosing regimens and their effect on the frequency and severity of ARIA-E in adults with early symptomatic Alzheimer's disease (AD) and explore participant characteristics that might predict risk of ARIA. Read Less

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.

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 study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies. Read Less

The purpose of this study is to determine whether CVL-871 is safe and tolerable in patients with Dementia-Related Apathy and if CVL-871 shows changes in clinical measurements of apathy. Read Less

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 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. Read Less

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

This is an extension study of the Phase 3 Studies 15-AVP-786-301, 15-AVP-786-302, and 17-AVP-786-305, which also allows participants from the Phase 2 Study 12-AVR-131 to be included. Read Less

This is a validation study to evaluate the acceptability, feasibility and preliminary efficacy of the Brain Health Program, a multimodal curriculum covering dementia risk factors and evidence-based change interventions. The goal of this study is to evaluate the Brain Health Program in individuals with identified risk factors for the onset of dementia and to prepare for a large-scale efficacy trial in this population.

This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide [d6-DM]/quinidine sulfate [Q]) compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer's type. Read Less

This is a multicenter randomized double-blind placebo-controlled Phase 2 study of an oral combination of tetrahydrocannabinol (THC) and cannabidiol (CBD) compared to placebo over 12 weeks. This study is designed to test the hypothesis that treatment with an oral combination of THC/CBD will reduce agitation hospice care-eligible patients with agitation and dementia as measured by the Cohen Mansfield Agitation Inventory (CMAI) when compared to placebo at 2 weeks. This study will enroll approximately 150 participants of any gender at least 40 years of age who are hospice care-eligible with agitation and dementia (HAD). Participants will be randomized (50:50) to either active study drug (T2:C100) or placebo. The double-blind period of this study is 12 weeks. A 24 week optional open-label extension will be offered to participants who complete the double-period. Read Less
