研究组 & 干预措施
Verteporfin and Ranibizumab
Photodynamic therapy with verteporfin in combination with ranibizumab injection. Patients received one treatment at baseline with verteporfin photodynamic therapy (PDT) in the study eye and thereafter based on re-treatment criteria at intervals of at least 90 days. Within 1-24 hours, patients also received Ranibizumab intravitreal injection on Day 1 and at Month 1 and 2 and thereafter according to the re-treatment criteria at intervals of at least 30 days through Day 150. From month 3 onward, re-treatments were determined based on study-specific re-treatment criteria that included evaluation of polyp progression on indocyanine green angiography (ICGA), and assessment of fluorescein angiograms and visual acuity.

Verteporfin monotherapy
Patients received one treatment at baseline with verteporfin photodynamic therapy in the study eye and thereafter based on re-treatment criteria at intervals of at least 90 days. Within 1-24 hours, patients also received Ranibizumab placebo (sham intravitreal injection) on Day 1 and at Month 1 and 2 and thereafter according to the re-treatment criteria at intervals of at least 30 days through Day 150. From month 3 onward, re-treatments were determined based on study-specific re-treatment criteria that included evaluation of polyp progression on indocyanine green angiography (ICGA), and assessment of fluorescein angiograms and visual acuity.

结局指标
主要结局
Number of Participants With Complete Regression (CR) of Polyps Measured by Indocyanine Green Angiography (ICGA)
时间窗: Month 6
Indocyanine green angiography (ICGA) assessments were performed using the Heidelberg Retinal Angiography 2 (HRA2) machine to measure the Total Lesion Area and the degree of polyp regression. Complete regression was defined as no polyps seen on the imaging.
次要结局
- Number of Participants With at Least One Complete Polyp Regression During 6 Months Assessed by ICGA(Baseline through end of study (6 months))
- Mean Change From Baseline in Central Retinal Thickness Measured by Optic Coherence Tomography (OCT)(Baseline and Month 6)
- Mean Change From Baseline in Best-corrected Visual Acuity (BCVA) of the Study Eye at Month 6(Baseline and Month 6)
