Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 50 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: * age-related macular degeneration (AMD) * choroidal neovascularization (CNV)

Who may be able to join

  • Sub-, extra- or juxta-foveal choroidal neovascularization (CNV) or macular scar due to AMD in the non-study eye.
  • No CNV or geographic atrophy in the study eye.
  • Best corrected visual acuity in the study eye of greater than 20/40 or better than 70 ETDRS letters.
  • Sufficiently clear ocular media and adequate pupillary dilatation to permit good quality fundus imaging of the study eye.
  • Subjects of either sex, aged 50 years.
  • Evidence of a signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial.
  • Willing and able to comply with scheduled visits, laboratory tests, and other trial procedures.

Who cannot join

  • Subjects presenting with any of the following will not be included in the study:
  • Evidence of manifest CNV by FA, color photography or ICG angiography in the study eye.
  • Any prior treatment for CNV to the study eye (excluding vitamins and AREDS formula).
  • Significant media opacities, including cataract, which might interfere with visual acuity assessments, or fundus imaging in the study eye. Subjects should not be entered if there is likelihood that they will require cataract surgery within the following 2 years.
  • Presence of other causes of choroidal neovascularization in the fellow eye, including pathologic myopia (spherical equivalent of -8 diopters or more negative, or axial length of 25 mm or more), the ocular histoplasmosis syndrome, angioid streaks, choroidal rupture, and multifocal choroiditis.
  • Any progressive eye disease other than AMD (eg, glaucoma, diabetic retinopathy) in the study eye.
Show all 11Show fewer
  • Presence of subretinal hemorrhage, serous or hemorrhagic pigment epithelial detachments, subretinal fibrosis or pigment epithelial tears or rips in the study eye.
  • Any medical condition that would interfere with the patient's ability to complete the trial.
  • Concurrent enrollment in any other observational or interventional clinical study.
  • Any treatment with an ocular or systemic investigational agent in the past 60 days for any medical condition.
  • Known serious allergies to the dye used in fluorescein angiography or ICG.

An observational study of Choroidal Neovascularization (CNV) and Age-related Macular Degeneration (AMD), run by Pfizer at 3 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identify the sequence of change in the chorioretinal interface during the development of CNV and the progression from dry to neovascular AMD. (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
