Group Intervention Description Verteporfin and Ranibizumab Verteporfin Photodynamic Therapy 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 and Ranibizumab 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 Verteporfin Photodynamic Therapy 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. Ranibizumab monotherapy Ranibizumab Patients received one treatment at baseline with verteporfin placebo (with sham 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 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.
- Primary Outcome Measures
Name Time Method Number of Participants With Complete Regression (CR) of Polyps Measured by Indocyanine Green Angiography (ICGA) 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.
- Secondary Outcome Measures
Name Time Method Number of Participants With at Least One Complete Polyp Regression During 6 Months Assessed by ICGA Baseline through end of study (6 months) 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.
Mean Change From Baseline in Central Retinal Thickness Measured by Optic Coherence Tomography (OCT) Baseline and Month 6 High resolution 6 meridian scans were performed to measure central retinal thickness.
Mean Change From Baseline in Best-corrected Visual Acuity (BCVA) of the Study Eye at Month 6 Baseline and Month 6 BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is approximately 20/20. An increase in the VA score indicates improvement in visual acuity.
