Alzheimer's Disease Paid Clinical Trials in California

This is a Phase Ia/Ib, two-part, randomized, placebo-controlled, double-blinded, first in human(FIH) study to evaluate the safety, tolerability, PK, and PD of ADEL-Y01 in healthy participants in Part 1 and participants with MCI due to AD and mild AD in Part 2. The study includes 2 parts: Part 1 (single ascending dose \[SAD\] and Part 2 (multiple ascending dose \[MAD\]). Read Less

The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Stage 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Stage 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.

This is a master protocol for 3 independent, seamlessly enrolling, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in patients with ADP * Substudy 1 (Phase 2) will evaluate efficacy and dose response of ACP-204 30 and 60 mg vs placebo. This substudy will be initiated first. * Substudies 2A and 2B (both: Phase 3) will be confirmatory studies of either both doses (ACP-204 30 and 60 mg, respectively) or a single dose from Part 1 vs placebo. Substudies 2A and 2B will be performed independently of each other and will commence after enrollment of Part 1. All 3 substudies will be analyzed independently of each other. Each substudy individually will consist of a screening period (up to 49 days); a double-blind treatment period (6 weeks); a safety follow-up period (30 days) for patients not rolling over into an open-label extension study; and vital status follow-up (for patients who terminated their substudy early).

The purpose of this study is to assess the effect of JNJ-64042056 on cognitive decline, as measured by Preclinical Alzheimer's disease Cognitive Composite 5 (PACC-5) compared with placebo. Read Less

The primary objective of the study is to determine the dose response of E2814, when concurrently administered with lecanemab, on the change from baseline at 18 months in cerebrospinal fluid (CSF) microtubule-binding region (MTBR)-tau-243 in participants with early Alzheimer's disease (AD).

The purpose of this research study is to test the study drug, referred to as remternetug, to determine its effectiveness for the study treatment of asymptomatic (at risk) Alzheimer disease in individuals with AD-causing mutations. This study will also investigate the effects of remternetug on biomarkers (measures of the disease including brain scans, blood and spinal fluid tests), examine safety data to identify any potential benefits or risks, and examine how well participants can tolerate remternetug. Stage 1 will determine if treatment with the study drug prevents or reverses amyloid beta (Aβ) accumulation compared with placebo in participants with dominantly inherited Alzheimer's disease (DIAD). Stage 2 will evaluate the effect of early anti-amyloid treatment on downstream biomarkers of AD in treated participants compared to external control groups. 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.

The goal of this clinical trial is to learn if restricting the time of eating to allow for prolonged fasting at night may reduce sleep disturbances, cognitive decay, and pathology in patients diagnosed with Mild Cognitive Impairment (MCI) or early to moderate Alzheimer's disease (AD). It will also learn about the feasibility of practicing 14 h of nightly fasting in this group of older adults. The main questions it aims to answer are: * Does prolonged nightly fasting of 14 h can reduce markers of AD pathology and aging and reduce cognitive and sleep alterations in MCI and AD patients? * Can patients with MCI and early /moderate AD sustain time-restricted eating for 3 to 6 months? Researchers will compare participants who fast for 14 h per night during 3 months to those who fast for less than 12 h/night. Researchers will also compare participants that fast for 3 months to those who fast during 6 months, to determine the effective duration of the intervention. Finally, researchers will evaluate whether following the time-restricted eating diet alongside a partner actively following the same diet, will increase adherence to the protocol compared to subjects that fast alone. Participants will: * Fast for 14 h a night (stop eating at 8 pm and start eating the following morning at 10 am) for 3 or 6 months * Visit the clinic three times (at the beginning of the study, 6 and 12 months later) * Provide blood samples and take a cognitive test during clinic visits * Keep a diary (or use an app on a smart phone) to record time of eating * Wear an activity tracker watch Read Less

Researchers want to learn if giving MK-1167 (the study medicine) along with acetylcholinesterase inhibitor (AChEI) therapy can improve symptoms of Alzheimer's disease dementia (AD dementia), such as memory and mental activity. AD dementia is the most common type of dementia. AChEI therapy is the standard treatment for AD dementia. The goals of this study are to learn: * If at least one dose level (amount) of MK-1167 works to improve a person's memory and thinking compared to a placebo * About the safety of MK-1167 and if people tolerate it Read Less

This is a multicenter randomized, double-blind, placebo-controlled Phase 2 study designed to evaluate the efficacy, safety, and tolerability of two doses of CT1812 compared to placebo in participants diagnosed with early Alzheimer's disease. Read Less

The purpose of the Trial-Ready Cohort - Down Syndrome (TRC-DS) is to enroll 120 healthy adults with Down syndrome (DS), between the ages of 25-55, into a trial ready cohort (TRC), and up to 450 participants in total including co-enrolled in the Alzheimer Biomarkers Consortium - Down Syndrome (ABC-DS) study. Participants enrolled in the TRC-DS will undergo longitudinal cognitive and clinical assessment, genetic and biomarker testing, as well as imaging and biospecimen collection. Using these outcome measures, researchers will analyze the relationships between cognitive measures and biomarkers of Alzheimer's disease (AD) to identify endpoints for AD clinical trials in DS that best reflect disease progression. To learn more about the study and participating sites, visit our study website at: https://www.trcds.org/. TRC-DS is collaborating with the Alzheimer's Disease Biomarker Consortium-Down Syndrome (ABC-DS) to allow study participants to be concurrently enrolled in both ABC-DS and TRC-DS, referred to as "co-enrollment". ABC-DS is a longitudinal, observational research study that is overseen at University of Pittsburgh Coordinating Center. ABC-DS participants who express interest in potentially joining a clinical trial in the future and who meet TRC-DS eligibility criteria, may choose to co-enroll in TRC-DS at an ABC-DS Site. Co-enrolled participants will adhere to the ABC-DS protocol and schedule of activities, but agree to share their data with the TRC-DS team and to receive invitations for future participation in clinical trials.
