Brief Summary

To evaluate the safety and tolerability of intravitreal injection of LX109 in patients with nAMD.

Detailed Description

In this study, 9 to 12 participants were enrolled in an open monocular, single dose escalation study design. Two dose groups were set up: low dose group (7×109 VG/ eye, 0.05ml) and high dose group (3.5×1010 VG/ eye, 0.05ml). Among them, 3 to 6 subjects were enrolled in low-dose group and 6 subjects were enrolled in high-dose group.

Eligibility Criteria

Exclusion Criteria

• 1. In the investigator's judgment, concomitant eye diseases of the study eye at screening or baseline may cause subjects to fail to respond to study therapy or confuse the interpretation of study findings. For example, diabetic retinopathy, retinal vein obstruction, retinal retinal detachment, macular hiatus (stage 3 or 4), uveitis, vitreous macular traction affecting central vision, macular anterior membrane involving macular fovea or damaging macular structure, equivalent spherical lens ≤-8.00D of the study eye, etc.

2. To investigate the presence of subretinal hyperreflective substance (SHRM) involving the fovea except CNV lesions; 3. Central serous chorioretinopathy (CSC) was confirmed in the study eyes at any time; 4. Study retinal detachment in the eye at any time; 5. Non-study eye BCV A less than decimal recorded visual acuity 0.05(<19 ETDRS letters); 6. The presence of uncontrolled glaucoma (defined as intraocular pressure ≥25mmHg after standard treatment) in the study eye; 7. Active intraocular or periocular inflammation or infection in the study eye or non-study eye; 8. To investigate the presence of CNV or macular edema secondary to causes other than AMD; 9. In the study, the refractive medium of the eye is seriously cloudy or the pupil cannot be sufficiently dilated, affecting BCVA or causing insufficient acquisition Clear eye imaging data, such as OCT, FFA, and fundus photography, affect researchers' observation of safety and efficacy.

Eye Treatment： 10. Internal eye surgery, such as vitrectomy, cataract phacoemulsification, trabeculectomy, or other filtering surgery, was performed within 3 months prior to baseline screening or study eye screening; 11. Study eyes screened or treated with intravitreal drug injections or drug-containing intraocular implants other than anti-VEGF drugs, such as intraocular corticosteroids, within 6 months prior to baseline; 12. Research eye or systemic have received gene therapy; 13. Study eyes screened or treated with macular laser photocoagulation or photodynamic therapy (PDT) or full vision membrane laser photocoagulation within 3 months prior to baseline; 14. Study eyes were screened or underwent YAG laser posterior capsulectomy or laser trabeculectomy or laser periiridectomy within 1 month prior to baseline
