Microcurrent Stimulation Therapy for Intermediate to Advanced Nonexudative Age-related Macular Degeneration

Prior treatment

• Treatment with photobiomodulation (PBM) therapy or short pulse laser within 12 months prior to screening.

Other illness

• 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.
• Known severe allergy to fluorescein dye.
• History of seizure disorders, chronic migraines and/or cluster headaches.
• 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 of intravitreal injections for GA (e.g., Syfovre or Izervay).
• 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.
• History of amblyopia.

Lab values

• Uncontrolled diabetes, defined as glycated haemoglobin (HbA1c) \>10% (13.3 mmol/L).

Other

• 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).
• 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).
• 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 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.
• 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.
• Visually significant cataracts and/or visually significant posterior capsular opacification.

• 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 \[20/40 to 20/200\])
