Polypoidal Choroidal Vasculopathy Clinical Trial
Official title:
A Random, Open-label Multicenter, Phase IV Study Assessing the Efficacy and Safety of Two Regimens of Anti-VEGF Therapy in Chinese Patients With Polypoidal Choroidal Vasculopathy
The study will evaluate the efficacy and safety of two different regimens of anti-VEGF Therapy (OCTA plus OCT guided 3+PRN vs. OCT guided 3+PRN) in Chinese patients with PCV. This study is to provide long-term safety data in the treatment of Chinese patients with PCV.

Primary | PCV lesion recurrence | PCV lesion recurrence is defined as the reappearance of new exudative biomakers (such as IRF, SRF, PED) or new hemorrhage detected on OCT or fundus examination in subsequent visits from the last visit showing clinical stability. PCV lesion recurrence rate will be compared at 24months between the two groups to assess the efficacy of OCTA plus OCT guided 3+PRN regimen. | 24 months | |
Secondary | Mean Snellen BCVA at every visit or treatment | Compare of mean Snellen Best-Corrected-visual-acuity at every visit or treatment between the two groups to assess the efficacy of OCTA plus OCT guided 3+PRN regimen. | 24 months | |
Secondary | Number of participants with treatment-related adverse events | Compare of Number of participants with treatment-related adverse events between the two groups to assess the safety of OCTA plus OCT guided 3+PRN regimen | 24 months | |
Secondary | Mean number of injections after the initial three loading dose monthly injections | Compare of mean number of injections after the initial three loading dose monthly injections between the two groups to assess the efficacy of OCTA plus OCT guided 3+PRN regimen. | 21 months | |
Secondary | Mean central macular thickness at every visit or treatment by OCT | Compare of mean central macular thickness by OCT at every visit or treatment between the two groups to assess the efficacy of OCTA plus OCT guided 3+PRN regimen. | 24 months |
