Efficacy of RGn600 in Patients With Mild-to-moderate Alzheimer's Disease

Efficacy of RGn600 in Patients With Mild-to-moderate Alzheimer's Disease: a Pivotal, Sham-controlled, Randomized, Double-blind, Multicentric Investigation (LIGHT4LIFE)

Source: ClinicalTrials.gov · Last updated 21 Aug 2026

Brief summary (registry, in English)

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.

  • Patient with a short-term life-threatening pathology (e.g., evolving cancer; non-stable heart failure; severe hepatic, renal or respiratory failure, etc.)
  • Patient with a risk of epileptic seizure
  • Patient with major physical or neurosensorial disorders that may interfere with neurological assessments

Other

  • Patient protected by a French legal measure ("sauvegarde de justice", "tutelle" or "curatelle")

  • Non-menopausal woman
  • Patient living in a medical facility
  • Patient with skin lesions on the treatment application area (abdomen or head)

  • Patient with a genetic form of AD
  • Patient with chronic psychosis or psychotic episodes
  • Patient with known and non-supplemented vitamin B12 and folic acid deficiencies
  • Patient with known untreated hypothyroidism
  • Patient not able to meet treatment sessions as deemed by the investigator
  • Patient not able to complete requested investigation assessments as deemed by the investigator.

Who the study is looking for

  • Male or female aged 55 to 85 years old (both included)
  • Diagnosed with AD according to McKhann et al. international criteria dated 2011
  • 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
  • In case of treatment with AD symptomatic treatments (memantine and acetylcholinesterase inhibitors) and psychotropic treatments (anxiolytics, antidepressants and neuroleptics): with a stable dose of such treatments 4 weeks before inclusion
  • Who has a caregiver who is sufficiently and regularly present and can help the patient throughout the investigation, as deemed by the investigator
