A Study of Longer Interval of IVT IBI302 in Subjects With nAMD
Study Details
Study Description
Brief Summary
The study is designed for multi-center, randomized, double-masked, active-controlled study to evaluate the longer interval of intravitreal injection of IBI302 in subjects with neovascular age-related macular degeneration.

Outcome Measures
Primary Outcome Measures
- Percentage of Participants Gaining ≥0,5,10,15 Letters From the Baseline BCVA in the Study Eye Over Time [From Baseline to week 52]
Best Corrected Visual Acuity (BCVA) was measured on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters. The BCVA letter score ranges from 0 to 100 (best score), and a gain in BCVA letter score from baseline indicates an improvement in visual acuity.
Secondary Outcome Measures
- Percentage of Participants Loss >0,≥5,10，15 Letters From the Baseline BCVA in the Study Eye Over Time [Baseline to week 52]
Best Corrected Visual Acuity (BCVA) was measured on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters. The BCVA letter score ranges from 0 to 100 (best score), and a loss in BCVA letter score from baseline indicates a decline in visual acuity.
- Change of Central Subfield Thickness in the Study Eye from baseline [Baseline to week 52]
Central subfield thickness (CST) was defined as the distance between the internal limiting membrane (ILM) and Bruch's membrane using optical coherence tomography (OCT), as assessed by the central reading center.
- Change of Total Area of Choroidal Neovascularization Lesion/Total Area of Choroidal Neovascularization Leakage in the Study Eye from Baseline [From Baseline to week 52]
The total area of the choroidal neovascularization lesion/Total Area of Choroidal Neovascularization Leakage in the study eye was evaluated by a central reading center using fundus fluorescein angiography (FFA).
- Percentage of Participants in different dosage of IBI302 Arm on Once Every 8-Weeks, 12-Weeks,Treatment Intervals [At Week 20,40,52]
- Safety Summary of the Overall Number of Participants With at Least One Adverse Event by Event Type, in All Participants [From Baseline to week 52]
This safety summary reports the number and percentage of participants who experienced at least one adverse event (AE) during the study. AEs are categorized as any AEs, ocular AEs occurring in the study eye or fellow eye, systemic AEs, serious AEs, AEs related to treatment with study drug, AEs of special interest. The investigator independently assessed the seriousness and severity for each AE. Severity was graded according to the following grading scale: Mild = Discomfort noticed, but no disruption of normal daily activity; Moderate = Discomfort sufficient to reduce or affect normal daily activity; Severe = Incapacitating with inability to work or to perform normal daily activity.
