What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Greater Than or Equal to ≥10 Letter (or 2 Line) Improvement in Vision at 1 Year
Refraction and best-corrected visual acuity (VA) measurements were performed using retro-illuminated, modified Ferris-Bailey Early Treatment Diabetic Retinopathy Study (ETDRS) charts
Measured: Baseline, Year 1
Secondary outcomes (11)
Number of Participants With a ≥ 10 Letter (or 2 Line) Improvement in Vision at 2 Years
Refraction and best-corrected VA measurements were performed using retro-illuminated, modified Ferris-Bailey ETDRS charts
Measured: Baseline, Year 2
Number of Participants With a ≥ 15 Letter Improvement in Vision at 1 Year
Refraction and best-corrected VA measurements were performed using retro-illuminated, modified Ferris-Bailey ETDRS charts
Measured: Baseline, Year 1
Number of Participants With a ≥ 15 Letter Improvement in Vision at 2 Years
Refraction and best-corrected VA measurements were performed using retro-illuminated, modified Ferris-Bailey ETDRS charts
Measured: Baseline, Year 2
Number of Eyes With a 2 or More Step Increase in Degree of Retinopathy at 1 Year
Retinopathy changes were monitored using fundus photography and fluorescein angiograph (FA) assessments. An Independent Reading Center, using trained graders, evaluated the presence of retinopathy using a modified 12-step version of the ETDRS Final Retinopathy Severity Scale, that ranged from step 1 (retinopathy level of 10 or 12) to step 12 (retinopathy level of 85A or 85B) where an increase in the step or retinopathy level indicated a worsening of the condition.
Measured: Baseline, Year 1
Number of Eyes With a 2 or More Step Decrease in Degree of Retinopathy at 1 Year
Retinopathy changes were monitored using fundus photography and FA assessments. An Independent Reading Center, using trained graders, evaluated the presence of retinopathy using a modified 12-step version of the ETDRS Final Retinopathy Severity Scale, that ranged from step 1 (retinopathy level of 10 or 12) to step 12 (retinopathy level of 85A or 85B) where a decrease in the step or retinopathy level indicated an improvement.
Measured: Baseline, Year 1
Number of Eyes With a 2 or More Step Increase in Degree of Retinopathy at 2 Years

Measured: Baseline, Year 2
Change From Baseline in Mean VA Score at 1 Year
Changes in VA monitored through refraction and best-corrected VA measurements using retro-illuminated, modified Ferris-Bailey ETDRS chart with participants at a 4-meter distance from chart. Distance VA expressed as an ETDRS score (number of letters correctly read) ranging from 0 to 60, where higher ETDRS scores represented better vision. Change from baseline for each patient equaled the visual acuity obtained at the observation minus the visual acuity at baseline.
Measured: Baseline, Year 1
Change From Baseline in Mean VA Score at 2 Years
Changes in VA monitored through refraction and best-corrected VA measurements using retro-illuminated, modified Ferris-Bailey ETDRS chart with participants at a 4-meter distance from chart. Distance VA expressed as an ETDRS score (number of letters correctly read) ranging from 0 to 60, where higher ETDRS scores represented better vision. Change from baseline for each patient equaled the visual acuity obtained at the observation minus the visual acuity at baseline.
Measured: Baseline, Year 2
Number of Participants Requiring Focal or Grid Laser Treatment During Year 1
Included focal laser coagulation, focal laser photocoagulation, panretinal laser photocoagulation, retinal laser coagulation, and retinal laser photocoagulation
Measured: 1 year
Number of Participants Requiring Focal or Grid Laser Treatment During Year 2
Included focal laser coagulation, focal laser photocoagulation, panretinal laser photocoagulation, retinal laser coagulation, and retinal laser photocoagulation
Measured: 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Macugen in people with Macular Edema Associated With Diabetes Mellitus, run by Pfizer at 73 sites in 18 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 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 73 sites in United States, France, Germany, Czechia, Brazil and 13 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 30 Mar 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants With Greater Than or Equal to ≥10 Letter (or 2 Line) Improvement in Vision at 1 Year (time frame: Baseline, Year 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00605280, which also lists 1 linked publication.
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Nov 2018; AzTrials last refreshed its copy on 6 Nov 2026.
