SCV09 synbiotic for improving behavioral symptoms in Alzheimer's disease

A Pilot, Single-arm Study on the Efficacy and Safety of the Use of a Synbiotic Formula (SCV09) in Alzheimer's Disease Patients

Not applicable Interventional Chinese University of Hong Kong · NCT06948929

This pilot will try a synbiotic formula called SCV09 to see if it improves dementia-related behavior in people aged 60–85 with Alzheimer's disease who have a caregiver to assist with treatment and sample collection.

What this trial studies

This is a pilot, single-arm study administering the synbiotic formula SCV09 to patients with Alzheimer's disease who meet preset cognitive and behavioral thresholds. Eligible participants aged 60–85 with HK-MoCA ≤20 and NPI-12 ≥10 and a stable Alzheimer's medication history will receive SCV09 while being monitored for safety and changes in behavior. Clinical visits and stool sample collection will be used to track behavioral outcomes and explore gut microbiota changes associated with treatment. Findings are intended to estimate efficacy and safety and to inform the design of a future larger randomized controlled trial.

Who should consider this trial

Good fit: Ideal candidates are people aged 60–85 with a clinical diagnosis of Alzheimer's disease, HK-MoCA ≤20, NPI-12 ≥10, stable Alzheimer's medications, and a caregiver who can assist with treatment and stool sample collection.

Not a fit: Patients with concomitant Parkinson's disease or other neurodegenerative conditions affecting daily activities, a history of stroke, severe organ failure, active malignancy, recent major abdominal surgery, or on dialysis would be excluded and are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, SCV09 could reduce dementia-related behavioral symptoms and improve daily functioning and caregiver burden.

How similar studies have performed: Some small studies targeting the gut-brain axis have shown promising signals, but evidence remains limited and the approach is still experimental.
