NCT05926011

Brief Summary

This is a controlled investigation, with randomization of the patients, which aims at demonstrating the efficacy of device RGn600 in treating patients with mild-to-moderate Alzheimer's disease (AD). RGn600 is a non-invasive medical device which is applied on the head (helmet) and on the abdomen (abdominal belt). It combines 2 technologies:

  • PhotoBioModulation (PBM), which involves exposure to light from the red to near-infrared wavelengths using lasers and Light Emitting Diodes (LEDs)
  • Static Magnetic Stimulation (SMS), which consists in the application of a static magnetic field. Considering previous investigations, this innovative technology could reduce inflammation on the brain-gut axis, implicated in the development of Alzheimer's disease.

  • With mild-to-moderate AD, i.e., 10 ≤ MMSE score ≤ 26
  • With blood analyses results (for: thyroid-stimulating hormone, vitamin B12, folate, complete blood count including platelets, electrolytes including calcium, creatinine, clearance, alanine aminotransferase, aspartate aminotransferase, bilirubin, coagulation, C-reactive protein) dated less than 1 year ago in line with AD diagnosis, as deemed by the investigator
  • With brain Computed Tomography (CT) or/and Magnetic Resonance Imaging (MRI) scan dated less than 1 year ago in line with AD diagnosis, as deemed by the investigator
  • Who has a caregiver who is sufficiently and regularly present and can help the patient throughout the investigation, as deemed by the investigator
  • Affiliated to French social security
