Objectives: To assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of 12 weekly infusions of solanezumab, an anti-β-amyloid (Aβ) antibody, in patients with mild-to-moderate Alzheimer’s disease. Cognitive measures were also obtained.; Methods: In this phase 2, randomized, double-blind, placebo-controlled clinical trial, 52 patients with Alzheimer’s disease received placebo or antibody (100 mg every 4 weeks, 100 […]

Objective: To preliminarily assess the safety and efficacy of transdermal nicotine therapy on cognitive performance and clinical status in subjects with mild cognitive impairment (MCI).; Methods: Nonsmoking subjects with amnestic MCI were randomized to transdermal nicotine (15 mg per day or placebo) for 6 months. Primary outcome variables were attentional improvement assessed with Connors Continuous […]
Effect of second-generation antipsychotics on caregiver burden in Alzheimer’s disease

Kaczynski, Richard,
Sultzer, David L.,
Schneider, Lon S.
Background: Alzheimer’s disease (AD) imposes a severe burden upon patients and their caregivers. Severity of psychiatric symptoms and behavioral disturbances is an important determinant of caregivers’ experience of burden. These symptoms may be improved with atypical antipsychotic treatment.; Objective: Data from the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer’s Disease (CATIE-AD) trial were used to evaluate […]
Concord grape juice supplementation and neurocognitive function in human aging

Polyphenol compounds found in berry fruits, in particular flavonoids, have been associated with health benefits including improvement in cognition and neuronal function with aging. Concord grape juice contains polyphenols, including anthocyanins and flavanols, and previous research has shown improvement in a number of human health conditions with grape juice supplementation. In the current study, older […]
Medication adherence and tolerability of Alzheimer’s disease medications: study protocol for a randomized controlled trial

Frame, Amie,
Hendrie, Hugh C.,
Callahan, Chris M.,

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: […]

Background: This study was designed to assess changes in brain volume and cognitive abilities in memantine-treated patients with Alzheimer’s disease (AD) by using an exploratory, single-arm, delayed-start design.; Methods: Cholinesterase inhibitor-treated patients with AD (N = 47; Mini-Mental State Examination score range: 15-23) were enrolled in an observational lead-in period (weeks: 1-24), followed by an […]
Memantine and functional communication in Alzheimer’s disease: results of a 12-week, international, randomized clinical trial

Post hoc analyses suggest that memantine treatment may provide communication-related benefits in patients with Alzheimer’s disease (AD). In this 12-week, international, randomized, double-blind, placebo-controlled trial of memantine (10 mg bid), the functional communication abilities of patients with AD (MMSE range: 10-19) were assessed using the Functional Linguistic Communication Inventory (FLCI; primary measure). Two combined subscales […]
Subgroup analysis of US and non-US patients in a global study of high-dose donepezil (23 mg) in moderate and severe Alzheimer’s disease

Yardley, Jane,
Mackell, Joan
To better understand responses in the large number of US-based patients included in a global trial of donepezil 23 mg/d versus 10 mg/d for moderate-to-severe Alzheimer’s disease (AD), post hoc exploratory analyses were performed to assess the efficacy and safety in US and non-US (rest of the world [RoW]) patient subgroups. In both subgroups, donepezil […]
Efficacy and safety of donepezil 23 mg versus donepezil 10 mg for moderate-to-severe Alzheimer’s disease: a subgroup analysis in patients already taking or not taking concomitant memantine
Doody, Rachelle S.,
Geldmacher, David S.,
Farlow, Martin R.,
Sun, Yijun,
Moline, Margaret,
Mackell, Joan
Background/aims: A large multicenter trial of donepezil 23 mg/day versus donepezil 10 mg/day for moderate-to-severe Alzheimer’s disease allowed patients taking concomitant memantine. We evaluated the efficacy/safety of donepezil 23 and 10 mg/day in this trial, with respect to concomitant memantine use.; Methods: Prespecified analysis of data from a 24-week, randomized, double-blind trial. Patients were randomized […]
