  Purpose

This study examines the effect of intravitreally administered VEGF Trap in patients with wet AMD.

The purpose of this trial is to assess the ocular and systemic safety and tolerability of repeated intravitreal doses of VEGF Trap in patients with subfoveal choroidal neovascularization (CNV) due to AMD.

Primary Outcome Measures:
  • Mean Change of CR/LT From Baseline at Week 12 [ Time Frame: Baseline and at Week 12 ]
    CR/LT measured in micrometers (µm); lower individual values represent better outcomes.


Secondary Outcome Measures:
  • Mean Percent Change of CR/LT From Baseline at Week 12 [ Time Frame: Baseline and at Week 12 ]
    CR/LT measured in micrometers (µm); a more negative percentage represents a better outcome

  • Mean Change in Best Corrected Visual Acuity (BCVA) as Measured by Early Treatment Diabetic Retinopathy Study (ETDRS) From Baseline at Week 12 [ Time Frame: Baseline and at week 12 ]
    Defined study baseline range of ETDRS Best Corrected Visual Acuity of: letter score of 73 to 25 (20/40 to 20/320) in the study eye; a higher score represents better functioning

  • Percentage of Participants Who Gained at Least 15 Letters of Vision in the ETDRS Letter Score From Baseline at Week 12 [ Time Frame: At Week 12 ]
    Defined study baseline range of ETDRS Best Corrected Visual Acuity of: letter score of 73 to 25 (20/40 to 20/320) in the study eye; a higher score represents better functioning

Detailed Description:

This is a double masked, prospective, randomized study in which five groups of approximately 30 patients meeting the eligibility criteria will be randomly assigned in a balanced ratio to receive a series of intravitreal (IVT) injections of VEGF Trap into the study eye at 4- or 12 -week intervals over a 12-week period.

After Week 12, patients will be evaluated every 4 weeks. Patients will remain on study or may be eligible to enter a long-term extension study, in which they will continue to receive VEGF Trap.

Criteria

Inclusion Criteria:

  • Subfoveal CNV secondary to AMD.

  • Significant subfoveal atrophy or scarring.

  • Prior treatment with the following in the study eye:

    • Subfoveal thermal laser therapy.
    • Submacular surgery or other surgical intervention for the treatment of AMD.
    • Extrafoveal laser coagulation treatment within 12 weeks prior to Day 1.
