Brief Summary

The purpose of this Phase 4 study is to evaluate the safety of aflibercept 8mg in patients with proliferative diabetic retinopathy without center-involved diabetic macular edema.

Detailed Description

Subjects will be administered intravitreal aflibercept 8mg every 4 weeks, starting at week 0 for 8 weeks, then may be extended by 4-week intervals with no maximum between treatments with an end of study visit at week 96. At any visit, it will be determined if supplemental treatment is needed as determined by disease activity assessment until there is no regression of disease is noted and the extension intervals will begin again.

Conditions

Proliferative Diabetic Retinopathy (PDR)

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

All subjects

Subjects will receive 8mg aflibercept at week 0, 4, and 8. At week 8, subjects will enter a variable treatment and extension approach where they may be extended by 4-week intervals with no maximum interval between treatments until the end of study visit at week 96.

Supplemental: Disease activity will be assessed at every 4-week visit and supplemental treatment with panretinal photocoagulation (PRP) as needed and/or intravitreal (IVT) 8mg aflibercept injections as determined by the regression patterns listed below.

No regression: subjects will receive 8mg aflibercept and PRP every 4 weeks until they exhibit total regression, whereafter they may be re-extended.

Partial regression: subjects will receive 8mg aflibercept every 8 weeks and not be extended until total regression is exhibited.
