Trial Outcomes & Findings for Pegaptanib for Retinal Edema Secondary to Diabetic Vascular Disease(Preserve) Study (NCT NCT01486238)

NCT ID: NCT01486238

Last Updated: 2013-07-16

Results Overview

The primary efficacy outcome measure is the proportion of subjects who gain two or more lines in BCVA score in the Study Eye compared with baseline at 24 weeks. The BCVA is to be measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol.

Participant Flow

Patients will be recruited from a single medical clinic (Valley Retina Institute), and randomly assigned 2:1 to Macugen® every 4 weeks (IVMac q4 arm) or Macugen® every 6 weeks (IVMac q6 arm). If both eyes are eligible, then one eye will be randomized into the trial.

All enrolled patients must have DME in one or both eyes. In patients with both eyes that meet criteria, only 1 eye will be considered eligible. All fellow eyes in these patients will be treated according to standard clinical guidelines.

PRIMARY outcome

Timeframe: 24 weeks

Population: Proportion of subjects who gain two or more lines BCVA was calculated.

The primary efficacy outcome measure is the proportion of subjects who gain two or more lines in BCVA score in the Study Eye compared with baseline at 24 weeks. The BCVA is to be measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol.

18 participants

SECONDARY outcome

Timeframe: 24 Weeks

Optical Coherence Tomography (OCT) will be used to assess the central foveal thickness of each patient. The mean change from baseline to week 24 will be calculated for each patient.

SECONDARY outcome

Timeframe: 24 weeks

There is a possibility that some subjects may not respond to the study treatment to which they have been assigned. Macular laser treatment is considered an alternative treatment for retinal edema. A lower proportion of subjects requiring macular laser treatment would indicate a superior treatment regimen. This will be assessed at week 12, and again at week 24.
