Reduced Fluence Photodynamic Therapy (PDT) With Visudyne in Combination With Lucentis for Age-Related Macular Degeneration
Study Details
Study Description
Brief Summary
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.

Outcome Measures
Primary Outcome Measures
- Mean Change in BCVA of ETDRS Letters From Baseline at 12 Months [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.
- Mean Letters Gained of Best Corrected Visual Acuity Using ETDRS Protocol [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.
Secondary Outcome Measures
- Time to First Retreatment After Loading Doses [12 months]
- Average Number of PDT Retreatments Over 12 Months [12 months]
- Central Macular Thickness Reduction on OCT [12 months]
- Average Number of Ranibizumab Retreatments Over 12 Months [12 months]

-
Choroidal neovascular membrane greater than 9 disc diameters in size.
-
Previous posterior vitrectomy in the study eye.
-
Concurrent disease in the study eye that could compromise visual acuity or require medical or surgical intervention during the study period.
