Objective: Ponezumab (PF-04360365) is a humanized anti-amyloid beta (Aβ) monoclonal antibody designed for treatment of Alzheimer disease (AD). A single 2-hour intravenous infusion of 0.1 to 10 mg/kg was previously shown to be safe and well tolerated in subjects with mild to moderate AD, with measurable effects on plasma and cerebrospinal fluid Aβ. This phase […]

Background: The class of acetylcholinesterase inhibitors (ChEI), including donepezil, rivastigmine, and galantamine, have similar efficacy profiles in patients with mild to moderate Alzheimer’s disease (AD). However, few studies have evaluated adherence to these agents. We sought to prospectively capture the rates and reasons for nonadherence to ChEI and determine factors influencing tolerability and adherence.; Methods/design: […]
Ginkgo biloba extract EGb 761® in dementia with neuropsychiatric features: a randomised, placebo-controlled trial to confirm the efficacy and safety of a daily dose of 240 mg

Schlaefke, Sandra
A multi-centre, double-blind, randomised, placebo-controlled, 24-week trial with 410 outpatients was conducted to demonstrate efficacy and safety of a 240 mg once-daily formulation of Ginkgo biloba extract EGb 761(®) in patients with mild to moderate dementia (Alzheimer’s disease or vascular dementia) associated with neuropsychiatric symptoms. Patients scored 9 to 23 on the SKT cognitive battery, […]
Memantine and brain atrophy in Alzheimer’s disease: a 1-year randomized controlled trial

Lemming, Ole,
Scheltens, Philip
The primary objective of this study was to evaluate the rate of total brain atrophy (TBA) with serial magnetic resonance imaging (MRI), using the Brain Boundary Shift Integral (BBSI), in patients with probable Alzheimer’s disease (AD) over the course of 52 weeks of treatment with memantine or placebo. This was a multi-national, randomized, double-blind, placebo-controlled, […]

Background: Preliminary evidence suggests that goal-oriented cognitive rehabilitation (CR) may be a clinically effective intervention for people with early-stage Alzheimer’s disease, vascular or mixed dementia and their carers. This study aims to establish whether CR is a clinically effective and cost-effective intervention for people with early-stage dementia and their carers.; Methods/design: In this multi-centre, single-blind […]
Pilot randomized controlled study of a histamine receptor inverse agonist in the symptomatic treatment of AD

Michelson, David
We performed a clinical trial to evaluate the effects of the histamine subtype-3 receptor inverse agonist MK- 0249 on cognition in AD patients. Mild-to-moderate AD patients were randomized 1:1 to 4 weeks of double-blind daily treatment with oral MK-0249 5-mg or placebo. Pharmacokinetic and PET data suggested that MK-0249 5-mg daily would achieve approximately 85% […]

Souvenaid aims to improve synapse formation and function. An earlier study in patients with Alzheimer’s disease (AD) showed that Souvenaid increased memory performance after 12 weeks in drug-naïve patients with mild AD. The Souvenir II study was a 24-week, randomized, controlled, double-blind, parallel-group, multi-country trial to confirm and extend previous findings in drug-naïve patients with […]
Longer duration of hormonal contraceptive use predicts better cognitive outcomes later in life
Background: The cognitive effects of postmenopausal hormone therapy (HT) have been studied extensively, but little is known about the relationship between premenopausal hormone use and cognition. Hormonal contraceptive use vs. nonuse may be a potential factor influencing cognitive processes in midlife. The aim of this study is to explore the effect of modification of hormone […]
11C-PiB PET assessment of change in fibrillar amyloid-beta load in patients with Alzheimer’s disease treated with bapineuzumab: a phase 2, double-blind, placebo-controlled, ascending-dose study

Background: Carbon-11-labelled Pittsburgh compound B ((11)C-PiB) PET is a marker of cortical fibrillar amyloid-beta load in vivo. We used (11)C-PiB PET to investigate whether bapineuzumab, a humanised anti-amyloid-beta monoclonal antibody, would reduce cortical fibrillar amyloid-beta load in patients with Alzheimer’s disease.; Methods: Patients with mild-to-moderate Alzheimer’s disease were randomly assigned to receive intravenous bapineuzumab or […]
