Experimental Alzheimer's drug aims to lower brain 'Tangles' in Early-Stage patients

NCT ID NCT05469360

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial tests a drug called NIO752 in 38 people with mild Alzheimer's or mild cognitive impairment due to Alzheimer's. The drug is given as one or two injections into the spinal fluid to see if it can lower levels of tau protein, a key marker of Alzheimer's damage. The main goal is to check safety and how well the drug works at reducing tau, not yet to improve symptoms.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
NIO752 (a drug injected into the spinal fluid to target tau protein)
What this could lead to
If successful, this could point toward a treatment that slows or stops Alzheimer's by reducing harmful tau protein buildup in the brain.
What could go wrong
This is a very early Phase 1 trial with only 38 participants, so it is primarily testing safety and dosing—not yet proven to help memory or thinking. The drug is injected into the spine, which carries risks like headache or infection.
