What this trial studies

This investigation evaluates the efficacy of the RGn600 device, which combines PhotoBioModulation and Static Magnetic Stimulation, in patients with mild-to-moderate Alzheimer's Disease. The study is multicentric and will enroll 108 patients in France, who will be randomized to receive either the active RGn600 device or a sham device over a 26-week treatment period. Patients will undergo treatment sessions and be assessed for cognitive function, quality of life, and other health metrics at multiple follow-up visits over a year. The aim is to determine if this innovative non-invasive approach can reduce inflammation linked to Alzheimer's Disease.

Who should consider this trial

Good fit: Ideal candidates are males and females aged 55 to 85 diagnosed with mild-to-moderate Alzheimer's Disease.

Not a fit: Patients with severe Alzheimer's Disease or those not meeting the eligibility criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve cognitive function and quality of life for patients with Alzheimer's Disease.

How similar studies have performed: While this approach is innovative, similar studies using photobiomodulation have shown promise, suggesting potential for success.
