Active clinical trials for "Alzheimer Disease"

Alzheimer's disease (AD) is a fatal degenerative disease of the brain for which there is no cure. AD causes brain cells to die. AD is thought to be caused by an excess of beta-amyloid (β-amyloid), a sticky protein in the brain that forms amyloid plaques. At autopsy, AD patients are required to have these amyloid plaques in the brain in order to have a definitive diagnosis of AD. Inhibiting the enzyme gamma-secretase (γ-secretase) lowers the production of β-amyloid. Semagacestat (LY450139) is a functional γ-secretase inhibitor and was shown to lower β-amyloid in blood and spinal fluid in humans tested thus far and in blood, spinal fluid, and brain in animals tested thus far. This study used several different tests to measure the effect of semagacestat on both β-amyloid and amyloid plaques for some participants. The build-up of amyloid plaques was measured by a brain scan that takes a picture of amyloid plaques in the brain. Other tests measured the overall function of the brain and brain size in some participants. In this trial, participants who initially received placebo (inactive sugar pill) were, at a certain point in the study, switched over to active drug, semagacestat. In other words, all participants could eventually receive active drug. Participation could last approximately 2 years. Participants taking approved AD medications were permitted to participate in this study and continue taking these medications during the study. All participants who completed this study had the option to continue receiving semagacestat by participating in an open-label study. Preliminary results from this study (H6L-MC-LFAN [LFAN]) and another similar study (H6L-MC-LFBC [LFBC; NCT00762411]) showed semagacestat did not slow disease progression and was associated with worsening of clinical measures of cognition and the ability to perform activities of daily living. Study drug was stopped in all studies. Studies LFAN, LFBC, and open-label H6L-MC-LFBF (LFBF; NCT01035138) were amended to continue collecting safety data, including cognitive scores, for at least 7 months. The Clinical Trial Registry (CTR) will reflect results of analyses from the original LFAN protocol in addition to those from the amended LFAN protocol.

This study will provide an initial assessment of the safety, tolerability, and pharmacokinetics (PK) of PAZ-417 after administration of ascending single oral doses to healthy young Japanese male and healthy elderly Japanese male subjects.

This is a Phase I, multicenter, randomized, double-blind, placebo-controlled study that will be conducted in the United States and consists of a single ascending-dose stage followed by a multidose, parallel-treatment stage. This study will be conducted in approximately 50 adult patients between 50-85 years old who have mild to moderate Alzheimer's disease.

This study will evaluate compliance, tolerability, safety, efficacy and caregiver burden of rivastigmine patch 10 cm² treatment in people with Alzheimer's disease (MMSE 10-26) initiating therapy for the first time with a cholinesterase inhibitor, and in patients who were unresponsive to previous cholinesterase inhibitor treatment in a community setting.

This is a first-in-humans study of GSI-136, a drug being developed for the treatment of Alzheimer Disease. The main purpose of this study is to determine whether GSI-136 is safe and tolerable in healthy young and healthy elderly subjects. The amount of drug in the body and the effects of the drug on the body will also be evaluated at certain timepoints.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of E2609 when administered as single doses to healthy adult volunteers and healthy elderly subjects. The study will consist of 2 parts:(1) a single dose in healthy adult volunteers, at doses up to 800 mg or the maximum dose that can be tolerated, (2) a single dose of 50 mg in healthy elderly volunteers.

This is a Phase II, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the safety and efficacy of MABT5102A in patients with mild to moderate Alzheimer's Disease.

Based on prior published pilot studies, the investigators have initiated a larger, multi-site placebo-controlled clinical trial with Alzheimer's disease (AD) patients and individuals diagnosed with Mild Cognitive Impairment (MCI), with the hopes of (1) confirming (or denying) the above promising clinical findings, and (2) determining whether or not our formulation can delay MCI "conversion" to AD.

This study will evaluate the effect of 150 mg MSDC-0160 taken daily for 90 days compared to the effect of placebo on changes in brain glucose utilization using FDG-PET and cognition in older persons with mild Alzheimer's disease. Safety and tolerability of MSDC-0160 in this population will also be studied. These results will be used to design larger studies of MSDC-0160 in persons with mild Alzheimer's disease.

This is a prospective, 26-week, open-label, single-arm multi-center pilot study. Eligible patients will receive open-label treatment with rivastigmine capsules plus memantine tablets as add on therapy. This study is designed to evaluate the safety and tolerability of add on therapy with memantine to rivastigmine capsules in patients with probable AD (MMSE 10-20)
