About

To assess the safety of intravitreal aflibercept injection in the treatment of proliferative diabetic retinopathy (PDR) by evaluating the incidence and severity of adverse events.

Full description

Single center, open label pilot study using 2.0mg intravitreal aflibercept injection. (IAI) 20 subjects with active PDR to be randomized into 2 groups, i.e. groups A and B. Subjects in both arms will be followed-up every 4 weeks until week 52. The primary endpoint of the study will be at week 52.

Subjects will be enrolled if the following criteria are met:

  • Ability to provide written informed consent and comply with study assessments for the full duration of the study
  • Age 18 years and older
  • Retinal neovascularization secondary to diabetic retinopathy
  • Best corrected visual acuity in the study eye better than 20/320 using an ETDRS chart
  • In the event that either eye of a potential subject meets enrollment criteria, the worse sighted eye will be enrolled into the study. Only one eye can be enrolled in the study.

Exclusion criteria

  • Participation in a study of an investigational drug or device within 30 days prior to potential enrollment into the study

  • Prior treatment with systemic anti-VEGF agents

  • Presence of any substantial ocular disease (other than diabetic retinopathy) that may compromise vision in the study eye and /or confound interpretation of the data; e.g. substantial cataracts, advanced glaucoma, optic neuritis, optic neuropathy or atrophy, marked macular atrophy, ocular vascular occlusion, history of retinal detachment, uveitis, viral or other forms of chorioretinitis, etc.

  • Prior treatment with anti-VEGF therapy in the study eye within 90 days of baseline

  • Prior treatment with PRP within 60 days

  • Active infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye

  • Uncontrolled glaucoma in the study eye (defined as IOP ≥ 25 mmHg despite treatment with anti-glaucoma medication)

  • History of cerebral vascular accident, myocardial infarction, transient ischemic attacks within 180 days of study enrollment.

  • History of allergy to fluorescein, topical antibiotic, povidone iodine (Betadine) or aflibercept.

  • Presence of vitreous hemorrhage that completely obstructs the view of the optic nerve (amount of vitreous hemorrhage will also be gated by 20/320 criteria)

  • Presence of TRD in the study eye.

  • Presence of pre-retinal fibrosis (not including epiretinal membrane)

  • Unwilling to discontinue sperm bank donation for any period of time after IAI treatment
