Primary Outcome Measures:
  • Mean Change From Baseline in Best-corrected Visual Acuity (BCVA) of the Study Eye at Month 12 [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    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.

  • Percent of Patients With a Treatment-free Interval of at Least 3 Months Following the Month 2 Visit [ Time Frame: Month 2 up to Month 11 ] [ Designated as safety issue: No ]
    The number of patients with a ranibizumab treatment-free interval, ie, no active ranibizumab treatments for at least 3 months duration (at least 2 consecutive monthly visits), anytime following the Month 2 ranibizumab treatment. Only active ranibizumab treatments were considered.


Secondary Outcome Measures:
  • Change From Baseline in Total Area of Leakage of the Study Eye at Month 12 [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    Total area of leakage of the study eye was assessed at the Central Reading Center (CRC) using Fluorescein angiography (FA).

  • Percentage of Patients With Fluorescein Leakage in the Study Eye at Month 12 [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
    The percentage of patients with leakage of the study eye was assessed at the Central Reading Center (CRC) using Fluorescein angiography (FA).

  • Change From Baseline in Central Retinal Thickness at Month 12 [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    Optical coherence tomography was performed in the study eyes and the evaluations of the images were performed by the central reading center.

Arms Assigned Interventions
Experimental: Verteporfin With Standard Fluence Rate Plus Ranibizumab
Patients received three consecutive monthly ranibizumab injections on Day 1 and at Months 1 and 2, and thereafter as needed at intervals of at least 30 days based on retreatment criteria. These patients also received verteporfin photodynamic therapy (PDT) with standard fluence (SF) rate on Day 1 and then as needed from Month 3 at intervals of at least 90 days based on the retreatment criteria. From month 3 onward, retreatments were determined based on study-specific retreatment criteria that included retinal thickness by Optical Coherence Tomography (OCT), sub-retinal hemorrhage evaluated by ophthalmoscopic examination, visual acuity assessed using Early treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart and choroidal neovascularization (CNV) leakage assessed by fluorescein angiography (FA). Patients received sham intravitreal injections for the first 12 months if retreatment with ranibizumab was not warranted based on the retreatment criteria.
Drug: Verteporfin Photodynamic Therapy
After a 10-minute intravenous infusion of verteporfin at a dose of 6 mg/m^2 body surface area, verteporfin was activated by light application of 50 J/cm^2 (Standard Fluence rate) or 25 J/cm^2 (Reduced Fluence rate) to the study eye, begun 15 minutes after the start of the infusion.
Other Name: Visudyne
Drug: Ranibizumab
Ranibizumab 0.5 mg administered as an intravitreal injection.
Other Name: Lucentis
Drug: Ranibizumab Placebo
To maintain masking, patients in the combination groups received sham intravitreal injections whenever retreatment with active Ranibizumab was not warranted based on the retreatment algorithm.
Active Comparator: Ranibizumab Monotherapy
Patients received monthly ranibizumab injections for 12 months and thereafter as needed based on the retreatment criteria. These patients were also administered verteporfin placebo infusion with sham PDT on Day 1 and then as needed from Month 3 at intervals of at least 90 days based on the retreatment criteria. Retreatments were determined based on study specific retreatment criteria that included retinal thickness by Optical Coherence Tomography (OCT), sub-retinal hemorrhage evaluated by ophthalmoscopic examination, visual acuity assessed using Early treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart and choroidal neovascularization (CNV) leakage assessed by fluorescein angiography (FA).
Drug: Ranibizumab
Ranibizumab 0.5 mg administered as an intravitreal injection.
Other Name: Lucentis
Drug: Verteporfin Placebo
To maintain masking, as a placebo for verteporfin photodynamic therapy, patients were administered a 10-minute intravenous infusion of 5% dextrose solution, followed by light application of 50 J/cm^2 to the study eye, begun 15 minutes after the start of infusion.
Experimental: Verteporfin With Reduced Fluence Rate Plus Ranibizumab
Patients received three consecutive monthly ranibizumab injections on Day 1 and at Months 1 and 2, and thereafter as needed at intervals of at least 30 days based on retreatment criteria. These patients also received verteporfin PDT with reduced fluence (RF) rate on Day 1 and then as needed from Month 3 at intervals of at least 90 days based on the retreatment criteria. From month 3 onward, retreatments were determined based on study-specific retreatment criteria that included retinal thickness by Optical Coherence Tomography (OCT), sub-retinal hemorrhage evaluated by ophthalmoscopic examination, visual acuity assessed using Early treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart and choroidal neovascularization (CNV) leakage assessed by fluorescein angiography (FA). Patients received sham intravitreal injections for the first 12 months if retreatment with ranibizumab was not warranted based on the retreatment criteria.
Drug: Verteporfin Photodynamic Therapy
After a 10-minute intravenous infusion of verteporfin at a dose of 6 mg/m^2 body surface area, verteporfin was activated by light application of 50 J/cm^2 (Standard Fluence rate) or 25 J/cm^2 (Reduced Fluence rate) to the study eye, begun 15 minutes after the start of the infusion.
Other Name: Visudyne
Drug: Ranibizumab
Ranibizumab 0.5 mg administered as an intravitreal injection.
Other Name: Lucentis
Drug: Ranibizumab Placebo
To maintain masking, patients in the combination groups received sham intravitreal injections whenever retreatment with active Ranibizumab was not warranted based on the retreatment algorithm.
