简要总结
This study evaluated the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity and anatomic outcomes compared to ranibizumab monotherapy and the durability of response observed in patients with choroidal neovascularization secondary to age-related macular degeneration.

研究组 & 干预措施
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.

结局指标
主要结局
Mean Change From Baseline in Best-corrected Visual Acuity (BCVA) of the Study Eye at Month 12
时间窗: Baseline and Month 12
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
时间窗: Month 2 up to Month 11
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.
