About this trial
The goal of this placebo-controlled double-blind Phase 2 clinical trial is to test in people with early Alzheimer's Disease.
The main questions it aims to answer are:
* Does treatment with fasudil, a ROCK-inhibitor, lead to significant improvement in working memory (based on computer-based working memory composite scores) compared to placebo in individuals with early Alzheimer's disease (AD) over 12 months? * What is the effect of fasudil treatment for 12 months on other cognitive functions, brain metabolism measured by Fluorodeoxyglucose Positron Emission Tomography (FDG-PET), and other relevant clinical functions and biomarkers in individuals with early Alzheimer's disease (AD)? * Treatment will be escalated to a maintenance dose of 120 mg total daily dose for up to 50 weeks, with regular clinic visits for efficacy and safety evaluations. * Assessments will include cognitive tests, FDG-PET scans, and biomarker analyses, with follow-up by the Data and Safety Monitoring Board for ongoing safety review.
The study will compare participants receiving fasudil with those receiving placebo to see if fasudil treatment leads to improvements in cognitive functions, brain metabolism measured by FDG-PET.
Eligibility criteria
Qualifiers
Early AD, eg Stage 3 MCI or Stage 4 (mild AD dementia), as recently defined by the FDA (2018; Figure 2)
A significant change on a validated AD amyloid or tau biomarker (as determined either by visual reading of amyloid PET scans using any of the approved ligands, or CSF Aβ 1-42 levels or blood p-tau 217 cut-offs as determined by the clinical research laboratory)
A CDR Global rating of 0.5 or 1.0 (Morris 1993) and have an MRI scan within the past two years that has no findings inconsistent with AD
Capacity to give informed consent based on the clinical judgement of an experienced clinician
Disqualifiers
Significant cerebrovascular disease, as indicated by clinical history, neurological examination, or on MRI (including cortical infarction or deep white matter or periventricular white matter hyperintensities with a Fazekas scale score of 3 (Fazekas et al 1987).
A history of cerebrovascular bleeding or severe bleeding of the digestive tract, lungs, nose or skin
Severe renal impairment (GFR <30) or serum creatinine or urea nitrogen values ≥3 times Upper normal limit (ULN) at screening or baseline
Moderate to severe hepatic impairment. Serum alanine transaminase (ALT) or aspartate transaminase levels ≥3 times ULN at screening or baseline
