Prior Ocular treatment:

• Prior Verteporfin PDT, external-beam radiation, laser photocoagulation, macular surgery, or transpupillary thermotherapy
• Prior local treatment with Pegaptanib, Ranibizumab, Bevacizumab or other anti-angiogenic compound or any investigational treatment in both eyes or systemic use of bevacizumab within 90 days prior to randomization
• History of intraocular surgery including pars plana vitrectomy and intraocular hemorrhage displacement is not allowed with the exception of uncomplicated cataract surgery that is allowed within 60 days prior to screening
• Ocular conditions that required chronic concomitant therapy within 90 days prior to randomization with topical, ocular, or systemically administered corticosteroids or any herbal medication known to contain steroid-like components

61 participants in 3 patient groups

Verteporfin and Ranibizumab

Experimental group

Description:

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.

Treatment:

Drug: Verteporfin Photodynamic Therapy

Drug: Ranibizumab

Verteporfin monotherapy

Active Comparator group

Description:

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.
