Primary Outcome Measures:
  • To determine the safety and tolerability of PF-04523655 when administered as a single intravitreal injection [ Time Frame: Over a 24-Month Period ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To describe anatomical changes in the retina and choroid following the administration of PF-04523655 [ Time Frame: Day 14 ] [ Designated as safety issue: Yes ]
  • To determine the changes in visual acuity ETDRS chart after a single intravitreal injection of PF-04523655 [ Time Frame: Day 14 ] [ Designated as safety issue: Yes ]
  • To evaluate the safety, efficacy and frequency of dosing following administration of PF-04523655 of approved VEGF-inhibitors in those study patients requiring rescue therapy [ Time Frame: Monthly ] [ Designated as safety issue: Yes ]
  • To evaluate early response after a single intravitreal administration of PF-04523655 in patients who, in the opinion of the investigator, have the potential to show improvement in visual acuity from other treatment options (Stratum 2 patients) [ Time Frame: Day 14 ] [ Designated as safety issue: Yes ]

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient is ≥ 50 years old and in general good health. Patients with medically controlled chronic disease such as HTN, AODM, and hyperlipidemia may be included.
  • Patient is capable of giving consent.
  • Patient is willing and able to comply with the visit schedule and study procedures including follow-up visits.
  • Patient has documented CNV secondary to AMD with evidence of active disease characterized by blood vessel leakage or evidence of hemorrhage.
  • Patient has clear ocular media and adequate pupil dilation to allow good quality imaging by fundus photography.
  • Patient's intraocular pressure is ≤ 25 mmHg

Exclusion Criteria:

  • Patient is of childbearing potential. Every female patient is considered of child-bearing potential unless she has had sterilization surgery or is post-menopausal and has not had a menstrual period for at least 12 months.
  • Patient has CNV due to causes other than AMD, including ocular or periocular infections.
  • Patient has lesions not easily imaged and quantified.
  • Patient has underlying systemic disease such as cardiac, neurological, infectious disease, uncontrolled diabetes mellitis, or disease of the eye other than AMD. Patient may have medically controlled glaucoma.
  • Patient is participating in any concurrent interventional study.
