New eye drug shows promise for blinding disease
NCT ID NCT06164587
First seen Jun 27, 2026 · Last updated Jul 21, 2026 · Updated 3 times
Summary
This early-stage trial tests an experimental drug called Kamuvudine-8 (K8) for people with geographic atrophy, a form of advanced age-related macular degeneration that causes vision loss. About 30 participants receive eye injections of K8 and are monitored for 26 weeks to check safety and whether the drug can slow vision decline or damage. The goal is to see if K8 is safe and worth testing in larger studies.

Inclusion Criteria: * Aged 50 or older, diagnosed with geographic atrophy (GA) due to age-related macular degeneration (AMD). * Best corrected visual acuity (BCVA) 24 or greater Early Treatment of Diabetic Retinopathy Study (ETDRS) letters (approximately Snellen 20/320 or greater), in study eye. * The entire geographic atrophy (GA) lesion must be completely visualized on the macula centered image and must be able to be imaged in its entirety and not contiguous with any areas of peripapillary atrophy except in such cases where there is a "neck" or some narrow area connecting the GA with the peripapillary atrophy, as determined by Fundus Autofluorescence (FAF) imaging at screening: * Both eyes must have GA and the total GA area in each eye must be ≥ 2.5 and ≤ 20.0 mm2 (1 and 8 disk areas \[DA\] respectively) * If geographic atrophy (GA) is multifocal, at least one focal lesion must be ≥ 1.25 mm2 (0.5 DA), with the overall aggregate area of GA, as specified above. * If geographic atrophy (GA) is unifocal, then the lesion must be extrafoveal. * Presence of any pattern of hyperautofluorescence in the junctional zone of geographic atrophy (GA). Absence of hyperautofluorescence (i.e., pattern = none) is exclusionary. * Fundus Autofluorescence (FAF), spectral-domain optical coherence tomography (SD-OCT), or Fluorescein Angiography (FA) imaging of entire geographic atrophy (GA)lesion at least 6 months prior to entry. General Exclusion Criteria: * Females who are pregnant, nursing, planning a pregnancy or who are of childbearing potential not using a reliable method of contraception * History or current evidence of hypersensitivity to any components of the study medication or fluorescein, as assessed by the investigator * Participation in any investigational drug or device study within 30 days prior to baseline * History or current evidence of a medical condition or medication use that may, in the opinion of the investigator, preclude the safe administration of study medication or affect the results of the study * Participation in any systemic experimental treatment or any other systemic investigational new drug within 6 weeks or 5 half-lives of the active ingredient (whichever is longer) prior to the start of study treatment. Clinical trials solely involving observation, over-the-counter vitamins, supplements, or diets are not exclusionary. Ocular Exclusion Criteria: * Active ocular or periocular infections, malignancy * History of major ophthalmic surgery in the past 3 months, and any ophthalmic surgery in study eye in the last 30 days * History of significant ocular disease other than AMD that may confound results * Any history or current evidence of exudative ("wet") AMD including any evidence of retinal pigment epithelium rips or evidence of retinal, choroidal, or peripapillary neovascularization in either eye * Known hypersensitivity to study drug or any of the excipients in implant * Macular atrophy secondary to a condition other than AMD * History of laser therapy in the macular region * Aphakia or surgically compromised/absent posterior capsule including presence of scleral fixated lenses. Note: YAG laser posterior capsulotomy for posterior capsule opacification done at least 60 days prior to screening is not exclusionary * History of prior posterior vitrectomy * History of prior intraocular gene therapy for any indication * History of extended hydroxychloroquine or pentosan polysulfate exposure (\> 3 months) * Current use of medications known to be toxic to the lens, retina, or optic nerve (e.g., deferoxamine, chloroquine/hydroxychloroquine \[Plaquenil®\], tamoxifen, phenothiazines, ethambutol, digoxin, pentosan polysulfate, and aminoglycosides). * Uncontrolled glaucoma (defined as intraocular pressure \>21mm Hg despite treatment with ocular hypotensive medications at baseline) * Prior participation in another interventional clinical study or treatment for GA in the study eye including topical, IVT, subretinal, suprachoroidal, periocular or oral medication or placebo within 5 half-lives of the active ingredient Prohibited Medications/Treatments: * Systemic anti-VEGF medications * Intravitreal injections of Syfovre (pegcetacoplan), Izervay (avacincaptad pegol) or other complement inhibitors in either eye * Gene therapy injections in either eye
