Objective: To explore the effects of telmisartan, an angiotensin II type 1 receptor blocker with peroxisome proliferator-activated receptor γ-stimulating activity, on the levels of Aβ1-42, interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α) and cognition in elderly hypertensive patients with Alzheimer’s disease (AD).; Methods: A total of 48 patients with probable AD and essential hypertension were randomly […]

Research shows that certain antihypertensives taken during midlife confer Alzheimer’s disease (AD) related benefits in later life. We conducted a clinical trial to evaluate the extent to which the angiotensin converting enzyme inhibitor (ACE-I), ramipril, affects AD biomarkers including cerebrospinal fluid (CSF) amyloid-β (Aβ) levels and ACE activity, arterial function, and cognition in participants with […]
Comparison of pharmacokinetics, pharmacodynamics, safety, and tolerability of the amyloid β monoclonal antibody solanezumab in Japanese and white patients with mild to moderate alzheimer disease

Objectives: Solanezumab is a humanized anti-amyloid β monoclonal antibody being developed as a passive immunization treatment to slow the progression of Alzheimer disease (AD). Pharmacokinetics (PK), pharmacodynamics, safety, and tolerability after a single dose of solanezumab were compared between Japanese and white patients with AD.; Methods: Japanese and white patients with mild to moderate AD […]

Amyloid-β (Aβ) producing enzymes are key targets for disease-modifying Alzheimer’s disease (AD) therapies since Aβ trafficking is at the core of AD pathogenesis. Development of such drugs might benefit from the identification of markers indicating in vivo drug effects in the central nervous system. We have previously shown that Aβ(1-15) is produced by concerted β-and […]

Background: Gantenerumab is a fully human anti-Aβ monoclonal antibody in clinical development for the treatment of Alzheimer disease (AD).; Objectives: To investigate whether treatment with gantenerumab leads to a measurable reduction in the level of Aβ amyloid in the brain and to elucidate the mechanism of amyloid reduction.; Design: A multicenter, randomized, double-blind, placebo-controlled, ascending-dose […]

Introduction: Type 2 diabetes (DM-2) increases the risk of developing Alzheimer´s disease (AD), and patients with AD are more likely to develop DM-2. DM-2 and AD share some pathophysiological features. In AD, amyloid-β (Aβ) is accumulated as extracellular plaques in the gray matter of the brain, while in DM-2 islet amyloid polypeptide (IAPP) is accumulated […]

We previously showed that amyloid-β 1-42 (Aβ(42)) levels in cerebrospinal fluid (CSF) were markedly altered in response to a 4-week dietary intervention in normal aging and mild cognitive impairment (MCI). Here, we re-examined the data to assess whether diet-induced effects on CSF Aβ(42) were modulated by high intensity physical activity (hi-PA). Normal older adults (n […]
Effect of immunotherapy with bapineuzumab on cerebrospinal fluid biomarker levels in patients with mild to moderate Alzheimer disease

Grundman, Michael,
Liu, Enchi
Background: Given the slow and variable clinical course of Alzheimer disease, very large and extended clinical trials are needed to identify a beneficial clinical effect of disease-modifying treatments. Therefore, biomarkers are essential to prove that an anti-β-amyloid (Aβ) drug candidate affects both Aβ metabolism and plaque load as well as downstream pathogenic mechanisms.; Objective: To […]

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 […]

Background: Alzheimer’s Disease Neuroimaging Initiatives (“ADNI”) aim to validate neuroimaging and biochemical markers of Alzheimer’s disease (AD). Data of the pilot European-ADNI (E-ADNI) biological marker programme of cerebrospinal fluid (CSF) and plasma candidate biomarkers are reported.; Methods: Six academic EADC centres recruited 49 subjects (healthy controls, subjects with mild cognitive impairment (MCI) and AD). We […]
