Evaluation of an Electric Stimulator for Medical Use by Personal (LRTPM1) for Visual Function in Early to Intermediate Dry Age-Related Macular Degeneration

2026년 7월 7일 업데이트: Nu Eyne Co., Ltd.

A Multicenter, Randomized, Double-Blind, Sham-Controlled, Parallel-Group Exploratory Clinical Trial Evaluating the Efficacy and Safety of an Electric Stimulator for Medical Use by Personal (LRTPM1) in Improving Visual Function in Patients With Early to Intermediate Dry Age-Related Macular Degeneration

The goal of this clinical trial is to evaluate the efficacy and safety of an electric stimulator for medical use by personal (LRTPM1) in patients with early to intermediate dry age-related macular degeneration.

The main questions this study aims to answer are:

  • Does the investigational device improve visual function, as assessed by best corrected visual acuity and contrast sensitivity?
  • What treatment-emergent adverse events occur during the study?

Participants will:

  • Be randomized to receive either active stimulation or sham stimulation
  • Apply the assigned investigational device at home once daily for 30 minutes over a 12-week treatment period
  • Visit the study site for eye examinations and safety assessments
  • Return for a follow-up visit 4 weeks after the end of treatment

상세 설명

This study is a multicenter, randomized, double-blind, sham-controlled, parallel-group exploratory clinical trial designed to evaluate the efficacy and safety of an electric stimulator for medical use by personal (LRTPM1) in patients with early to intermediate dry age-related macular degeneration. Eligible participants will be randomized to receive either active stimulation or sham stimulation and will apply the assigned investigational device at home once daily for 30 minutes over a 12-week treatment period, followed by a 4-week post-treatment follow-up visit. The primary objective is to evaluate changes in visual function, as assessed by best corrected visual acuity measured using the ETDRS visual acuity chart and contrast sensitivity testing. Secondary objectives include evaluating changes in geographic atrophy parameters on fundus autofluorescence, drusen area and volume on optical coherence tomography, and vision-related quality of life as assessed by the NEI VFQ-25. Safety will be evaluated based on treatment-emergent adverse events, vital signs, physical examinations, and ophthalmic examinations throughout the study period.

  6. Participants with ocular media opacity or other conditions that, in the investigator's opinion, may make ophthalmic imaging difficult to interpret, including cataract, vitreous opacity, or vitreous hemorrhage
  7. Participants with uncontrolled chronic systemic diseases, including diabetes mellitus or chronic kidney disease, or a history of malignancy, except for cases with no recurrence within the past 5 years and no history of chemotherapy
  8. Participants with autoimmune diseases, including Sjögren's syndrome, rheumatoid arthritis, systemic lupus erythematosus, or Graves' disease
  9. Participants with severe hearing impairment, sensory abnormalities, or cognitive impairment that may make it difficult to properly perform the study procedures or recognize or report adverse events
  10. Participants who are hypersensitive to orbital nerve stimulation and are unable to receive treatment
  11. Participants with a history of drug or alcohol abuse
  12. Participants diagnosed with psychiatric disorders, including depression, schizophrenia, bipolar disorder, or dementia
  13. Participants who have participated in another clinical trial within 30 days prior to screening
  14. Participants who are considered to have other contraindications to use of the investigational medical device, including underlying cardiac disease, seizure-related disorders, implanted metal or electronic devices in the head or neck area including deep brain stimulators, unexplained pain, implanted or wearable pacemakers, or other conditions listed in the product precautions and contraindications. Dental implants are exempt.
  15. Participants who, in the opinion of the investigator, are deemed inappropriate for participation in the study
  16. Female participants of childbearing potential who do not agree to use medically accepted contraception during the study period. Medically accepted methods of contraception include condoms, oral contraceptives used consistently for at least 3 months, injectable or implantable contraceptives, or intrauterine devices.

실험적: Experimental Group (Active Stimulation, n=20)
Participants randomized to the active stimulation group will receive the investigational electric stimulator for medical use by personal (LRTPM1). Participants will apply the assigned device at home once daily for 30 minutes over a 12-week treatment period, followed by a 4-week post-treatment follow-up.
장치: Transcutaneous Electrical Stimulation
The active intervention uses transcutaneous electrical stimulation (TES) delivered by the investigational personal-use electric stimulator (LRTPM1). Electrodes are attached to the ocular and periocular area, and the device delivers pulsed electrical stimulation. Participants will apply the assigned device once daily for 30 minutes over a 12-week treatment period.
