Brief Summary
The purpose of this study was to assess the efficacy and safety of the anti-Vascular Endothelial Growth Factor (VEGF) agent ranibizumab (0.5 mg) with or without Panretinal laser photocoagulation (PRP) compared to PRP alone in patients with Proliferative Diabetic Retinopathy (PDR).

Outcome Measures
Primary Outcomes (1)
Change From Baseline in Area of Neovascularizations (NVs) at End of Core Study (EOCS)
The area of neovascularizations (NV) was assessed by a central reading center via fluorescein angiography (FA) images. The area of NV was calculated as the sum of area of neovascularization of the disc (NVD) and neovascularization elsewhere (NVE) and was recorded in square millimeters. A higher positive change value may indicate a greater formation of new, abnormal blood vessels and thus disease progression. One eye (study eye) contributed to the analysis.
Baseline, EOCS
Secondary Outcomes (8)
Change From Baseline in Area of Neovascularizations (NVs) at Month 3
Baseline, Month 3
Best Corrected Visual Acuity (BCVA) (ETDRS Letters) at EOCS

Study Arms (3)
Ranibizumab mono
EXPERIMENTALInterventional Core Phase: One intravitreal injection of ranibizumab 0.5 mg to the study eye monthly until stability regarding morphological parameters is confirmed (ie, no further improvement of morphology or no worsening of morphology for 3 consecutive months)
PRP mono
ACTIVE COMPARATORInterventional Core Phase: Panretinal laser photocoagulation (PRP) treatment administered to the study eye in accordance with the modified diabetic retinopathy study (DRS) guidelines for panretinal laser photocoagulation procedures
Ranibizumab+PRP
EXPERIMENTALInterventional Core Phase: Ranibizumab 0.5 mg as described for the ranibizumab mono arm and PRP treatment as described for the PRP mono arm until stability regarding morphological parameters is confirmed
Interventions
Pre-filled syringe for intravitreal injection
PRP treatment following DRS guidelines

- Masking Details
- An open-label design was chosen in which the evaluation of the primary objective was performed by a reading center. The reading center that evaluated the primary and several secondary objectives was blinded to randomization and therefore assessed these objectives uninfluenced by treatment information. However, laser burns were visible on the images, and no full blinding regarding panretinal laser photocoagulation (PRP) was possible for the reading center.
