Treating neurological disease through non-invasive ultrasound
Ceretas is developing a non-invasive, safe and portable therapeutic ultrasound platform to treat diseases of the brain.
Our platform is designed to restore devastating neurodegenerative diseases such as Alzheimer’s disease. We aim to unlock targeted drug delivery to the brain, reduce the burden of dementia and address other neurological conditions including depression and addiction.

Neuromodulation
Neuromodulation using focused ultrasound safely modulates neuronal activity.
Preclinical data suggests neuromodulation may be an effective standalone treatment for Alzheimer’s disease and other forms of dementia.
Clearing Aggregated Proteins
The blood-brain barrier is a selective semi-permeable membrane between the blood and the brain. Focused ultrasound has been shown in preclinical animal models to be able to temporarily open the blood-brain barrier.
Emerging research by our team indicates that opening this barrier has the potential to clear aggregated proteins in the brain and improve cognition in Alzheimer’s patients.
Enhancing Drug Delivery via Blood-Brain Barrier Opening
The blood-brain barrier prevents 98% of small-molecule drugs and nearly 100% of large biologics from reaching the brain which limits the ability of many drug candidates to treat conditions such as Alzheimer’s and depression.
When used alongside microbubbles, focused ultrasound has the potential to open the blood-brain barrier and allow these drugs to reach targeted areas of the brain.
Portable
Our portable focused ultrasound device is designed for easy mobility, allowing for seamless use across various clinical settings. Lightweight and compact, it ensures efficient treatment and enhanced drug delivery anywhere.
Low Cost
Focused ultrasound offers high-quality, accurate treatment at a lower price. Efficient and accessible, it enables broader adoption without compromising results.
Non-invasive
Designed for non-invasive treatment, the device delivers therapeutic ultrasound without surgery or discomfort. It enhances drug delivery and supports disease management while ensuring patient safety and ease of use.
One Device, Multiple Applications

Selective neuromodulation to treat neurodegenerative disease
Neuromodulation is a series of techniques that act upon a person’s nervous system for therapeutic benefit. Exisiting neuromodulation techniques are invasive or limited to shallow brain targets.
Focused ultrasound can selectively target precise regions of the brain, selectively modulating neuronal activity without causing damage or substantial heating.
Our world-leading research team based at the Queensland Brain Institute have demonstrated the efficacy of focused ultrasound in multiple preclinical and clinical studies:
- Preclinical animal studies showed restoration of brain function, including memory and improved cognition.
- A Phase 1 safety trial in 12 patients with mild to moderate Alzheimer’s disease showed the treatment to be safe and well-tolerated.
- A 60 patient Phase 2 trial is expected to begin in 2025, focused on treating the behavioural and psychological symptoms of dementia (BPSD).

Clearing aggregated proteins linked to Alzheimer's disease
Focused ultrasound, combined with microbubbles has been shown to be able to temporarily open the blood-brain barrier. The blood-brain barrier is a barrier between the brain’s blood vessels (capillaries) and the cells and other components that make up brain tissue.
In preclinical animal studies, the team at the Queensland Brain Insitute has shown that protein aggregates such as amyloid plaques and tau tangles can be cleared by opening the blood-brain barrier. These aggregated proteins are linked to Alzheimer’s disease.


Enhancing drug delivery by opening the blood-brain barrier
The blood-brain barrier prevents the vast majority of potential drug treatments from reaching the brain. This limits the ability of many drug candidates to treat conditions such as Alzheimer’s disease and depression.
Focused ultrasound, when used alongside microbubbles, is able to temporarily open the blood-brain barrier, allowing drugs that otherwise couldn’t cross into the brain to reach their targets. This significantly expands the drug candidates for treating mental and neurological conditions.
