Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the safety and tolerability of suprachoroidally administered CLS-AX following intravitreal anti-VEGF therapy in subjects with neovascular age-related macular degeneration (AMD)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diagnosis of neovascular age-related macular degeneration in the study eye.
* Active subfoveal choroidal neovascularization (CNV) secondary to AMD
* Two or more prior anti-VEGF intravitreal injections
* EDTRS BCVA score ≤ 75 and ≥ 20 letters

Exclusion Criteria

* Any active ocular disease, ocular disorders or conditions, prior ocular surgery or infection in the study eye other than nAMD
* Other than IVT anti-VEGF treatments, no topical ocular or intraocular or periocular corticosteroid, or other treatments for CNV
* IOP ≥ 25mmHg or cup-to-disc ratio \>0.8
* Uncontrolled systemic disease (high risk or evidence of arterial and venous thromboembolism, CVA or stroke, unstable cardiovascular disease, uncontrolled hyperthyroidism, poor glycemic control, gastrointestinal bleed and/or high risk of GI perforation or fistula formation) or any other condition or therapy that would make the participant unsuitable for the study
* Currently enrolled in an investigational drug or device study or has used an investigational drug or device within 30 days or the Screening visit
