Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ranibizumab
104 patients with an eligible study eye were randomized to be treated with Ranibizumab IVT. 0.5 mg of commercially available Ranibizumab were used for intravitreal injection adminstered by an unblinded injecting physician. 3 injections were performed (Baseline, Month 1, Month 2).
Procedure: Neovascular Age-related Macular Degeneration
Blood measurement
Other Names:
  • Lucentis, Eylea
Active Comparator: Aflibercept
101 patients with an eligible study eye were randomized to be treated with Aflibercept IVT. 2.0 mg of commercially available Aflibercept were used for intravitreal injection admistered by an unblinded injecting physician. 3 injections were performed (Baseline, Month 1, Month 2).
Procedure: Neovascular Age-related Macular Degeneration

  • Lucentis, Eylea

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline at Month 3 in Plasma VEGF Following Intravitreal (IVT) Injection of Anti-VEGF Agent
Time Frame: Change from baseline at Month 3
Percent change in blood VEGF level is calculated as the difference in blood VEGF level measured after 3 month of anti-VEGF agent IVT treatment (Ranibizumab or Aflibercept) when compared to baseline blood VEGF level.
Change from baseline at Month 3

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline in Plasma VEGF Level Overtime
Time Frame: Change from baseline up to month 3
Plasma VEGF measurement performed at all visits and compared to baseline level
Change from baseline up to month 3
Correlation Between Percent Change From Baseline Plasma VEGF Level and the Serum Anti-VEGF Agent Overtime
Time Frame: pre-dose to post-dose at Baseline, week 1, week 2, month 1, month 2, and month 3
VEGF level and anti-VEGF concentration measured in the blood at each single visit, including pre- and post-dose measurement at the dosing visits.
pre-dose to post-dose at Baseline, week 1, week 2, month 1, month 2, and month 3
Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) of the Study Eye Over Time
Time Frame: Baseline, month 1, month 2, month 3
BCVA score is assessed on study eye based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity charts at a testing distance of 4 meters. An increase in score indicates an improvement in acuity. Change from baseline calculated as observed post-baseline value - baseline value.
Baseline, month 1, month 2, month 3
Mean Change From Baseline in Central Retinal Thickness (CRT) of the Study Eye Over Time
Time Frame: Baseline, month 1, month 2, month 3

CRT in micrometers assessed by Optical Tomography (OCT) at each single study visit. A reduction is thickness indicates an improvement is the lesion area.

Change from baseline calculated as observed post-baseline - baseline value.
Baseline, month 1, month 2, month 3
Number of Patients With Ocular and Systemic Adverse Events
Time Frame: Day 1 to day 85
The incidence of reported treatment emergent adverse events (TEAEs) and treatment emergent serious adverse events (TESAE).
Day 1 to day 85
