Active clinical trials for "Alzheimer Disease"

This first time study in humans was designed to assess tolerability and safety of repeated subcutaneous injections of ABvac40, an active immunization against the C-terminal end of Abeta1-40.

This is a Phase 1, randomized, double-blind, placebo-controlled, 6-period crossover study to evaluate the effects of BPN14770 10 mg and 50 mg in reversing scopolamine-induced cognitive impairment in healthy volunteers. A positive control, donepezil 10 mg, will be included, and additivity of BPN14770 50 mg to donepezil 10 mg in reversing scopolamine effects will also be evaluated.

clinical trial to assess the efficacy of Acetyl-L-carnitine

Alzheimer's disease (AD) is a common neurodegenerative disease characterized by the accumulation of amyloid plaques and neurofibrillary tangles. Current consensus is that the AD pathological process begins decades before clinical symptoms occur. This long "preclinical" phase of AD might first become detectable in middle-age as deposits of hyperphosphorylated tau (P-tau) in the transentorhinal cortex and subcortical nuclei such as the locus coeruleus (LC) and the nucleus basalis of Meynert. There is strong preliminary evidence showing that cerebrospinal fluid (CSF) levels of orexin-A (OxA) are associated with increased P-tau (r=.52, p<.01) and total-tau (T-tau) (r=.42, p<.01) in cognitively normal older adults (mean age: 69.6±8.6 years). This study poses that onset of tauopathy in the LC results in down regulation of orexin receptors, leading to a homeostatic increase of OxA production by the hypothalamus, which results in changes in core body temperature (CBT) and sleep disruption that cause further neurodegeneration. This hypothesis will be tested by demonstrating that increases in CSF P-tau are associated in vivo with tau PET uptake, and that tau binding in the LC is associated with increases in CSF OxA (Aim 1); and second, by analyzing the downstream consequences of increased central nervous system (CNS) OxA on sleep architecture and CBT (Aim 2). To test these hypotheses, 19 older adults (age 55-75) balanced by sex, will first perform a full clinical evaluation and PET-MRI where Tau burden will be analyzed by PET-MR using 18F-MK6240 (visits 1-2). Subjects will later undergo 7 days of actigraphy followed by nocturnal polysomnography (NPSG) for 2 consecutive nights (N1-2) during which we will measure CBT (visits 3-4). A morning lumbar puncture (LP) will be performed after N2 to obtain CSF.

This study evaluates the effect of ORM-12741 on agitation/aggression symptoms in Alzheimer's disease. Two thirds of the patients will receive ORM-12741 and one third will receive placebo.

A method of detecting amyloid in the retina has been developed. A specially designed retinal camera will directly visualze and record retinal amyloid and via image processing will generate a number: the retinal amyloid index (RAI). The amount of retinal amyloid correlates with cerebral amyloid and has a predictive value in Alzheimer's disease. Telomere attrition accounts for cellular aging and is felt to have a pivotal role in Alzheimer's disease. The investigators plan to screen individuals to select those having retinal amyloid then evaluate an oral telomerase activator to determine if its use can alter the RAI over time compared to placebo.

This is a Phase I, randomized, placebo-controlled, double-blind study to evaluate the safety, tolerability, pharmacokinetics, and preliminary activity of RO7105705 in two participant populations: healthy participants and participants with mild-to-moderate Alzheimer's disease. This study is a single dose, dose-escalation, and multiple dose study comprising approximately six single dose cohorts in healthy participants administered RO7105705, either intravenously (IV) or subcutaneously (SC), and comprising one or more multiple dose cohorts in healthy participants administered RO7105705 IV every week (QW), a total of 4 doses, and one or more multiple dose cohorts in participants with Alzheimer's disease administered RO7105705 IV QW, a total of 4 doses.

The purpose of this study is to evaluate the safety, tolerability and efficacy of LY3002813 in early symptomatic Alzheimer's disease.

This study is a Phase 2, randomized, placebo controlled, dose ranging study of piromelatine (5, 20, and 50 mg daily for 6 months) versus placebo to determine an effective dose based on efficacy (cognitive performance), safety and tolerability in patients with mild dementia due to AD.

The purpose of this study is to determine if oxaloacetate (OAA) is safe and tolerable at doses of up to 2 grams per day in people with Alzheimer's disease (AD).
