Official title: Amyloid clearing therapy in dementia with Lewy bodies plus Alzheimers disease (ACT DLB+)

Funded at Stanford University · NIH-11264576 · Data updated 2026-11-12

A study tests an amyloid-clearing antibody in people who have both Dementia with Lewy bodies and Alzheimer's disease to see if it can safely help with their symptoms.

Who could benefit from this research

Could help

Adults diagnosed with both Dementia with Lewy bodies (DLB) and Alzheimer's disease pathology (DLB+AD).

Less likely to help

Some participants may not experience clinical benefit and could face treatment-related risks or adverse effects.

What this research studies

This patient-facing study investigates whether a monoclonal antibody that clears amyloid can be safely used in individuals with both DLB and AD. It is a phase 2, double-blind, placebo-controlled trial enrolling about 400 participants, with an additional 12-month observational follow-up to collect more clinical, imaging, and biomarker data. By combining AD and DLB pathology in a single trial, researchers aim to understand potential benefits or harms in this specific mixed-dementia population. If successful, the study could inform future treatment options for patients with co-occurring DLB and AD. The research is conducted at Stanford University and will involve close monitoring for adverse effects and meaningful changes in disease markers.

Why it matters

Potential benefit: If successful, participants may experience slowed disease progression or stabilization of symptoms and gain access to close medical monitoring and biomarker insights.

How similar studies have gone: Previous amyloid-clearing antibodies have shown safety and efficacy signals in Alzheimer's disease, but data in DLB+AD is not yet established.
