5. Study Description
Brief Summary
The purpose of this study is to examine the plasma concentration of vascular endothelial growth factor (VEGF) after standard treatment with one of the newest growth factor inhibitors, aflibercept (Eylea).
Patients with exudative age-related macular degeneration (AMD) are treated today with anti-growth factors (anti-VEGF). Eylea appears to have a longer duration of action in the eye and a more powerful effect on the edema in the macula than previously used growth factor inhibitors. This means that the disease can be controlled with fewer number of injections into the eye and the investigators can therefore reduce the risk of complications associated with this type of treatment.
It is unclear what the plasma VEGF concentration after treatment with Eylea into the eye in patients with wet age-related macular degeneration is.
Detailed Description
Macular edema secondary to exudative age-related macular degeneration is treated today primarily with vascular endothelial growth factor inhibitors, anti-VEGF.
There are currently four anti-VEGF drugs that are either approved or off-label used in ophthalmology. Pegaptanib (Macugen, Pfizer), ranibizumab (Lucentis, Novartis) aflibercept (Eylea, Bayer) and bevacizumab Avastin, Roche) . They have different molecules and pharmacodynamics .
VEGF plays an important role in many physiological and pathophysiological mechanisms. Studies have shown that even low-dose intravitreal treatment with bevacizumab leads to significant reduction of VEGF plasma concentration up to a month after treatment in patients with exudative AMD.
No significant systemic effect could be detected after intravitreal administration of ranibizumab or pegaptanib.
The purpose of this study is :
To determine if intravitreal treatment with Eylea affects VEGF plasma levels in patients with exudative AMD
How long after intravitreal injection is VEGF plasma concentration affected?
