Bumetanide in Patients With Alzheimer's Disease
Sponsor: Stanford University
Summary
This study aims to investigate bumetanide in patients with biologically confirmed Alzheimer's disease (AD). Bumetanide is a potent diuretic administered orally and is FDA approved for the treatment of edema and hypertension. Repurposing bumetanide as a medication for AD has been proposed based on data that demonstrated its ability to "flip" the APOE genotype-dependent transcriptomic signatures in AD mouse and cell culture models. Critically, this discovery was subsequently explored in Electronic Health Record cohorts, which revealed that among individuals over the age of 65, bumetanide exposure was significantly associated with a lower prevalence of AD in three independent datasets. Primary Objective: To evaluate the safety and tolerability of bumetanide when administered to participants with biomarker-confirmed Alzheimer's disease. Secondary Objective: To evaluate the clinical and biomarker effects of bumetanide in participants with mild cognitive impairment or mild dementia due to Alzheimer's disease.
Official title: Phase IIa, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Safety and Tolerability of Bumetanide in Patients With Alzheimer's Disease.

Bumetanide
Bumetanide is an FDA approved loop diuretic that has been used for more than three decades to treat edema, congestive heart failure, and hypertension across the life span. It has a well-known side effect profile. Most importantly it can cause dehydration and electrolyte imbalance especially at higher doses. This medication is given to individuals at the similar age group as Alzheimer's disease patients and Alzheimer's disease or cognitive impairment do not preclude its use in patients who need it for its FDA indications. At low doses and when titrated carefully, the medication is well tolerated. However, it has not been studied specifically in Alzheimer's disease patients.
Placebo
A placebo has no active properties and is taken orally.
