A multicenter, double-blind, placebo-controlled trial of the PDE9A inhibitor, PF-04447943, in Alzheimer’s disease

Ambrose, Darlene,
Altstiel, Larry D.
Background: PF-04447943 is a potent, selective phosphodiesterase 9A (PDE9A) inhibitor that elevates guanoscine 3′,5′ – cyclic monophosphate (cGMP) in brain and cerebrospinal fluid. PDE9A inhibition enhances synaptic plasticity and improves memory in preclinical cognition models, and prevents decreases in dendritic spine density in transgenic mice that overexpress amyloid precursor protein (APP) leading to high levels […]

Objective: To investigate the effect of a medical food on cognitive function in people with mild Alzheimer’s disease (AD).; Methods: A total of 225 drug-naïve AD patients participated in this randomized, double-blind controlled trial. Patients were randomized to active product, Souvenaid, or a control drink, taken once-daily for 12 weeks. Primary outcome measures were the […]

Background: Bapineuzumab, a humanized anti-amyloid-beta monoclonal antibody, is in clinical development for the treatment of Alzheimer’s disease.; Methods: We conducted two double-blind, randomized, placebo-controlled, phase 3 trials involving patients with mild-to-moderate Alzheimer’s disease–one involving 1121 carriers of the apolipoprotein E (APOE) ε4 allele and the other involving 1331 noncarriers. Bapineuzumab or placebo, with doses varying […]

Sabbagh, Marwan N.,
Agro, Albert,
Bell, Joanne,
Aisen, Paul S,
Schweizer, Edward,
Galasko, Douglas
Objective: To evaluate the safety and tolerability of PF-04494700, an oral inhibitor of receptor for advanced glycation end products, in patients with mild-to-moderate dementia of the Alzheimer type.; Methods: Patients aged 50 years and older who met the National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer’s Disease and Related Disorders Association criteria for Alzheimer […]
Evaluating the cognitive effects of donepezil 23 mg/d in moderate and severe Alzheimer’s disease: analysis of effects of baseline features on treatment response
Sabbagh, Marwan,

Christensen, Daniel,
Doody, Rachelle,
Farlow, Martin,
Liu, Liang,
Mackell, Joan,
Fain, Randi
Background: Treatment of Alzheimer’s disease with acetylcholinesterase inhibitors can result in symptomatic benefits, but patients often show variable responses. The objective of this post hoc analysis was to investigate relationships between easily identifiable baseline characteristics/demographics and cognitive response in patients treated with either donepezil 23 mg/d or 10 mg/d and to identify factors potentially influencing response.; Methods: […]

Objective: To assess the safety and tolerability of high-dose creatine, the feasibility of enrolling premanifest and 50% at-risk subjects in a prevention trial, and the potential of cognitive, imaging, and blood markers.; Methods: Sixty-four eligible consenting participants were randomly allocated (1:1) to 15 g twice daily of creatine monohydrate or placebo for a 6-month double-blind […]
Repetitive transcranial magnetic stimulation combined with cognitive training is a safe and effective modality for the treatment of Alzheimer’s disease: a randomized, double-blind study

Gonen, Ofer,
Marton, Revital Gendelman,
Khaigrekht, Michael
Cortical excitability can be modulated using repetitive transcranial magnetic stimulation (rTMS). Previously, we showed that rTMS combined with cognitive training (rTMS-COG) has positive results in Alzheimer’s disease (AD). The goal of this randomized double-blind, controlled study was to examine the safety and efficacy of rTMS-COG in AD. Fifteen AD patients received 1-h daily rTMS-COG or […]
Fracture prevention in patients with cognitive impairment presenting with a hip fracture: secondary analysis of data from the HORIZON Recurrent Fracture Trial
Prieto-Alhambra, D.,
Judge, A.,
Arden, N. K.,
Cooper, C.,
Lyles, K. W.,
Javaid, M. K.
Unlabelled: Patients with cognitive impairment (CI) often do not receive secondary fracture prevention. Use of zoledronic acid led to a similar reduction in re-fracture risk but the survival benefit was limited to those without CI.; Introduction: We tested whether the effects of id (Zol) on re-frazoledronic accture and mortality differed in patients presenting with a […]

Importance: Agitation is common, persistent, and associated with adverse consequences for patients with Alzheimer disease. Pharmacological treatment options, including antipsychotics are not satisfactory.; Objective: The primary objective was to evaluate the efficacy of citalopram for agitation in patients with Alzheimer disease. Key secondary objectives examined effects of citalopram on function, caregiver distress, safety, cognitive safety, […]
