R‑etodolac to protect brain blood vessels in Alzheimer’s

Repurposing of R-etodolac for Alzheimer's disease and related disorders

['FUNDING_OTHER'] · AUGUSTA UNIVERSITY · NIH-10985019

This work looks at whether R‑etodolac, a safer form of an arthritis drug, can help remove harmful amyloid from brain blood vessels and protect the brain in people with Alzheimer’s disease.

What this research studies

From my perspective, the team is repurposing R‑etodolac, the R‑enantiomer of the NSAID etodolac, because it may avoid the COX2-related side effects of the racemic drug. Their lab and animal work showed etodolac can restore blood–brain barrier function and reduce amyloid (Aβ) toxicity, and they plan experiments to see if R‑etodolac strengthens tight and adherens junction proteins and upregulates β‑catenin to reduce vascular Aβ. The project includes preclinical testing and development steps aimed at moving toward clinical use while monitoring for safety advantages of the R‑enantiomer. If clinical steps proceed, patients with Alzheimer’s or cerebral amyloid angiopathy might be asked to provide samples or consider early-phase participation.

Who could benefit from this research

Good fit: Ideal candidates would be people diagnosed with Alzheimer’s disease or cerebral amyloid angiopathy, particularly in early or moderate stages when vascular amyloid is present.

Not a fit: People without amyloid-related vascular disease, those with non-amyloid dementias, or patients with contraindications to NSAID-derived treatments may not benefit.

Why it matters

Potential benefit: If successful, this could slow or reduce vascular amyloid buildup and help preserve brain function in people with Alzheimer’s disease.

How similar studies have performed: Some laboratory and animal studies of etodolac and other NSAIDs showed protective effects on the blood–brain barrier and amyloid, but clinical trials of NSAIDs for Alzheimer’s have mostly failed, so using the R‑enantiomer is a novel and less-tested approach.
