Systemic VEGF Protein Dynamics Following Intravitreal Injections of Ranibizumab Versus Aflibercept in Patients With Visual Impairment Due to Diabetic Macular Edema (TIDE DME)
October 26, 2016 updated by: Novartis Pharmaceuticals
A Randomized, Single-blinded, Multicenter, Phase IV Study to Compare Systemic VEGF Protein Dynamics Following Monthly Intravitreal Injections of 0.5 mg Ranibizumab Versus 2 mg Aflibercept Until Study Week 12 in Patients With Visual Impairment Due to Diabetic Macular Edema
The purpose of the study is to compare the effect of intravitreal injections of ranibizumab and aflibercept on systemic VEGF protein levels in DME patients in a detailed time course.

Description
Inclusion Criteria:

Exclusion Criteria:
- Stroke or myocardial infarction less than 3 months prior to screening.
- Presence of uncontrolled systolic blood pressure or diastolic blood pressure
- Renal failure requiring dialysis or renal transplant or renal insufficiency
- Untreated diabetes mellitus
- Use of any systemic anti-VEGF drugs
- Use of systemic or inhaled corticosteroids for at least 30 consecutive days within 3 months prior to screening.

For fellow eye
- Retinal or choroidal neovascularization or macula edema of any cause
Other protocol-defined inclusion/exclusion criteria may apply.
