Neovascular (Wet) AMD
Conditions
Brief summary
This will be a clinical study to assess initial safety and tolerability of IVT ABI-110 in patients diagnosed with wet macular degeneration (wAMD), including symptomatic macular PCV.
Detailed description
This is a Phase 1/2a, open-label, multiple-cohort, dose-escalation study to evaluate the safety, tolerability, and preliminary efficacy of IVT ABI-110 (AAV2.N54-VEGF-Trap) injection in subjects with wAMD), including symptomatic macular PCV. This trial will include a screening period, confirmation of response to EYLEA (aflibercept), single administration of ABI-110, and follow-up period of 104 weeks after IVT ABI-110 injection.

Inclusion criteria
Key Inclusion Criteria: * General: 1. Must be willing and able to provide written, signed informed consent. 2. Age: Subjects ≥ 50 and ≤ 89 years of age at the time of signing the informed consent Study eye: 3. Diagnosis of wAMD, including symptomatic macular PCV, confirmed by the Central Reading Center 4. The macular neovascularization lesion must be confirmed as determined by the Central Reading Center based on SD-OCT imaging at screening. 5. BCVA ≤ 20/25 and ≥ 20/250 (≤ 80L and ≥ 30L ETDRS letters) 6. History of ≥ 2 anti-VEGF injections prior to trial entry with meaningful response to anti-VEGF and continued need for anti-VEGF treatment 7. Response to anti-VEGF at trial entry Key
Exclusion criteria
* Study or Fellow Eye: 1. Prior gene therapy, either eye 2. Any active ocular/intraocular infection or inflammation (e.g., blepharitis, infectious conjunctivitis, keratitis, scleritis, uveitis) or history of idiopathic or autoimmune-associated uveitis, either eye 3. History of retinal disease other than wAMD or PCV, study eye 4. Any condition preventing visual acuity improvement (e.g., fibrosis, atrophy, or retinal epithelial tear in the center of the fovea), study eye. 5. History of (or active) retinal detachment, study eye 6. Uncontrolled glaucoma (defined as IOP \> 25 mmHg despite treatment), study eye, or history of steroid-response ocular hypertension/glaucoma in either eye 7. History of intravitreal therapy, (other than anti-VEGF therapy) such as intravitreal steroid injection or investigational product, in the 6 months prior to screening, study eye 8. Any prior treatment with photodynamic therapy or laser photocoagulation, study eye 9. History of glaucoma filtration, vitrectomy, or other procedure that could affect drug distribution or clearance, study eye.
