Evidence of proliferative diabetic retinopathy with:
- Active retinal neovascularization defined by fluorescein angiography as non-high risk proliferative diabetic retinopathy (PDRP; NVD < 1/3 disc area; NVE < ½ disc area) or
- High risk PDRP treated with prior panretinal laser photocoagulation (PRP), showing persistent, active retinal neovascularization. The last session of PRP should not be within 12 weeks prior to enrolment.
Diabetes (Type I or II) must be stable which is defined as not requiring a change in medication over the last 4 weeks
Age ≥ 18
For female subjects of child-bearing age, a negative serum pregnancy test is mandatory. For subjects with reproductive potential, a willingness to utilize adequate contraception and not become pregnant. Adequate contraceptive measures include oral contraceptives (stable use for two or more cycles prior to Screening); IUD; Depo-Provera®; Norplant® System implants; condom or diaphragm used in conjunction with contraceptive sponge, foam or jelly; and abstinence.
Ability to regular follow-up visits
Patients requiring laser coagulation or intravitreal therapy with steroids or anti-VEGF drugs for diabetic macular edema within the first 6 months after enrolment
Patients with laser coagulation or any intravitreal therapy within three months prior to enrollment Media opacification not allowing adequate retinal examination
Allergy to fluorescein (Fluorescein Angiography)
Known HIV antibody, hepatitis B surface antigen, and/or hepatitis C antibody
History of malignancy except basal cell skin carcinoma prior to study entry
History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibody
