BACKGROUND The precise mechanisms whereby cardiovascular risk factors increase the risk of Alzheimer’s disease (AD) have not been delineated. We reported that microvessels isolated from AD brains overexpress a diverse array of neurotoxic and inflammatory proteins, which is consistent with the process of vascular activation. In pre-clinical studies using AD animal models we showed that a vascular activation inhibitor reduced vascular-derived neuroinflammation and improved cognitive performance. Thrombin is a key mediator of cerebrovascular activation in AD. OBJECTIVE This study aims to investigate the safety and potential efficacy of the direct thrombin inhibitor dabigatran, in patients with mild cognitive impairment (MCI) or mild AD to decrease vascular-derived neuroinflammation and improve cognitive performance. METHODS Participants will be enrolled then evaluated quarterly throughout the 24-month study. This is a 24-month randomized-control, double-blind, placebo-controlled, multicenter, delayed-start, pilot study evaluating thrombin inhibition in people with biomarker-confirmed MCI probably due to AD or mild AD. 40 - 60 participants will be recruited between 50 - 85 years old. In the initial 9-months of study, either dabigatran or placebo will be orally administered to patients at a dose of 150 mg per day. After 9 months of the placebo-control (Phase I), the placebo arm will cross-over to an active, open-label (Phase II) where all patients will be treated with a 150 mg daily dose of dabigatran orally for an additional 12 months. A 3-month non-treatment follow-up period will assess duration of effects. RESULTS Beginning in July 2019, and concluding in August 2022, this study is expected to publish final results in January 2023. CONCLUSIONS BEACON is a first-in-kind randomized clinical trial targeting thrombin activation in AD therapeutics. This trial will stimulate translational investigations of an FDA-approved drugs in a newly defined therapeutic areas. CLINICALTRIAL Clinicaltrials.gov NCT03752294

ABSTRACT Life expectancy in Brazil has increased markedly over the last 30 years. Hence, age-related disorders, such as Alzheimer's disease (AD), warrant special attention due to their high prevalence in the elderly. Pharmacologic treatment of AD is based on cholinesterase inhibitors (ChEI) and memantine, leading to modest clinical benefits both in the short and long-term. However, clinical response is heterogeneous and needs further investigation. Objective: To investigate the rate of response to ChEI in AD after three months of treatment. Methods: Patients with mild or moderate dementia due to probable AD or to AD associated with cerebrovascular disease were included in the study. The subjects were assessed at baseline and again after three months of ChEI treatment. Subjects were submitted to the Mini-Mental State Examination (MMSE), Mattis Dementia Rating Scale, Katz Basic Activities of Daily Living, Pfeffer Functional Activities Questionnaire, Neuropsychiatric Inventory and Cornell Scale for Depression in Dementia. Good response was defined by a gain of ≥2 points on the MMSE after three months of treatment in relation to baseline. Results: Seventy-one patients, 66 (93%) with probable AD and five (7%) with AD associated with cerebrovascular disease, were evaluated. The good response rate at three months was 31.0%, being 37.2% and 21.4% in mild and moderate dementia, respectively. There were no significant differences on most tests, except for improvement in hallucinations, agitation and dysphoria in moderate dementia patients. Conclusion: The rate of good clinical response to ChEI was higher than usually reported. Specific behavioral features significantly improved in the subgroup of moderate dementia.
