  Purpose

This study will assess the efficacy and safety of Ranibizumab alone or in combination with laser treatment vs. laser treatment alone in Proliferative Diabetic Retinopathy. Efficacy will be primarily measured by the change of area of neovascularizations as measured by Fluorescein Angiography at month 12 (difference to baseline value).

Drug: Ranibizumab
Procedure: Laser photocoagulation
Procedure: Ranibizumab & laser photocoagulation
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Multicenter Randomized Open-label Three-arms Controlled 12 Months Clinical Proof of Concept Study to Evaluate Efficacy and Safety of Ranibizumab Alone or in Combination With Laser Photocoagulation vs. Laser Photocoagulation Alone in Proliferative Diabetic Retinopathy

Primary Outcome Measures:
  • Change of area of neovascularizations as measured by Fluorescein [ Time Frame: baseline and month 12 ] [ Designated as safety issue: No ]
    Area of NVs will be measured via FLA images by Reading Cente


Secondary Outcome Measures:
  • BCVA in all patients (ETDRS letters) [ Time Frame: baseline and month 12 ] [ Designated as safety issue: No ]
    Best corrected visual acuity (BCVA) will be measured using standardized ETDRS charts

  • Change in classification of DR based on the ETDRS severity scale (assessed by FP) [ Time Frame: baseline, month 3 and month 12 ] [ Designated as safety issue: No ]
    Reading Center will evaluate severity scale using Fundus Photography images

  • Change in retinal thickness (OCT) [ Time Frame: baseline, month 3 and month 12 ] [ Designated as safety issue: No ]
    Central retinal thickness will be measured using OCT images graded by Reading Center

  • Rates of patients (%) [ Time Frame: baseline, month 3 and month 12 ] [ Designated as safety issue: No ]
    with ≥ 5/10/15 ETDRS letters gain -with no clinical relevant change (less than 5 letters gain or loss, "stable visual acuity") -with ≥ 5/10/15 ETDRS letters loss -with improvement in BCVA (ETDRS letters)
