What this trial studies

This clinical trial evaluates the safety and effectiveness of the i-Lumen AMD transpalpebral microcurrent device in patients with intermediate to advanced nonexudative age-related macular degeneration (AMD). Participants will undergo an initial loading regimen followed by seven maintenance sessions over 11 months, with monthly evaluations for three months post-treatment. The study aims to determine how this therapy impacts vision and overall eye health in affected individuals.

Who should consider this trial

Good fit: Ideal candidates are individuals with intermediate to advanced nonexudative AMD, specifically those with large drusen and a visual acuity letter score between 35 to 70.

Not a fit: Patients with implanted electrical devices, uncontrolled diabetes, or severe dry eye may not benefit from this therapy.

Why it matters

Potential benefit: If successful, this therapy could improve vision and quality of life for patients suffering from advanced stages of age-related macular degeneration.

How similar studies have performed: While this approach is relatively novel, similar studies exploring microcurrent therapy for eye conditions have shown promising results.

Eligibility criteria

Show full inclusion / exclusion criteria
Key Inclusion Criteria:

* Presence of at least one large druse \>125 microns in diameter due to AMD.
* BCVA letter score of 35 to 70 letters (inclusive) (Snellen equivalent 6/12 to 6/60 \[20/40 to 20/200\])

Key Exclusion Criteria:

* Any implanted electrical device(s) including deep brain stimulator, hearing or visual implants (i.e., cochlear implant, auditory brainstem implant, retinal prostheses), and/or cardiac defibrillator/pacemaker.
* Implanted metallic device within 20 cm of the Treatment electrode (study eye(s)) and/or the grounding electrode (base of the hairline on the back of the neck).
* Uncontrolled diabetes, defined as glycated haemoglobin (HbA1c) \>10% (13.3 mmol/L).
* Current tobacco or tobacco-related product use or history within the past 5 years of heavy smoking (defined as, on average, more than half a pack of cigarettes per day).
* Known severe allergy to fluorescein dye.
* Medical diagnosis of severe dry eye defined as requiring either artificial tears more than six (6) times a day or prescription drops (i.e., Restasis, Xiidra, or Cequa).
* History of seizure disorders, chronic migraines and/or cluster headaches.
* History and/or evidence of diabetic retinopathy in either eye as assessed by CF, fundus fluorescein angiography (FA), and OCT, to be confirmed by the Central Reading Centre.
* Other conditions which pre-dispose to chorioretinal atrophy such as inherited retinal dystrophy (i.e., Stargardt's disease, Best's disease, pattern dystrophy, central areolar choroidal dystrophy, etc.).
* History and/or evidence of exudative AMD in the study eye as assessed by CF, FA (or OCT-A ), and OCT, to be confirmed by Central Reading Centre.
* GA involving the foveal centre, as assessed by the Central Reading Centre using AF and OCT.
* History of intravitreal injections for GA (e.g., Syfovre or Izervay).
* Treatment with photobiomodulation (PBM) therapy or short pulse laser within 12 months prior to screening.
* Glaucoma requiring ≥3 medications and/or drops per day, or history of trabeculectomy.
* History of any kind of intraocular surgery, excluding cataract surgery performed ≥3 months from Screening.
* History of yttrium aluminium garnet (YAG) laser posterior capsulotomy \<1 month from Screening.
* Visually significant cataracts and/or visually significant posterior capsular opacification.
* History of amblyopia.
