Primary Outcome Measures:
  • Change from baseline in OCT retinal thickness; evaluate the safety and tolerability of doses. [ Time Frame: After 12 months of therapy. ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Evaluation of visual acuity; change from baseline in OCT center-point retinal thickness; the need for focal/grid laser photocoagulation during the study; the progression of diabetic retinopathy [ Time Frame: After 12 months of therapy. ] [ Designated as safety issue: No ]
