简要总结
In this pilot study the researchers will evaluate the safety and efficacy of 50% reduced fluence PDT combination therapy with ranibizumab. The researchers hope to gain information regarding the use of reduced fluence PDT combination therapy. The information gained from this pilot study may prompt further definitive studies comparing the safety and efficacy of both standard fluence PDT combination therapy, reduced fluence PDT combination therapy, and ranibizumab monotherapy.
The study will compare the use of combination therapy with ranibizumab and verteporfin PDT to ranibizumab alone in patients with exudative age-related macular degeneration (AMD). All patients will receive three consecutive monthly treatments with ranibizumab. Patients will be randomized 1:1:1 to 3 groups. Patients randomized to group 1 will receive only ranibizumab. Patients randomized to group 2 will also receive one treatment with reduced fluence (50% fluence) verteporfin PDT at day 0. Patients randomized to group 3 will also receive one treatment with standard fluence verteporfin PDT. All patients will also be evaluated for possible retreatment with ranibizumab and verteporfin PDT according to established criteria. Thirty patients will be recruited from one U.S. sites. Randomization will occur at the time of entry into the study. Follow-up will continue until month 12 (from day 0) in all subjects.

结局指标
主要结局
Mean Change in BCVA of ETDRS Letters From Baseline at 12 Months
时间窗: 12 months
Visual acuity is often measured using a chart called the ETDRS chart (Early Treatment Diabetic Retinopathy Study). A letter score is calculated based on the number of letters that can be correctly identified from specified distances. Higher letter scores correspond to better visual acuity. Lower letter scores mean poorer visual acuity. In this study the baseline visual acuity in letters is subtracted from the visual acuity in letters measured at the 12 month visit providing a letter score of vision gain or vision loss.
