Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This study is designed to specifically target on patients with diabetic macular oedema who are poorly responsive to current anti-VEGF therapy (bevacizumab or ranibiznumab), and evaluate whether changing the therapeutic agent to intravitreal ziv aflibercept injection would lead to improved functional and anatomical outcomes. The 48 week treatment duration is appropriate for a pilot study.
The hypothesis of this study is that compounded intravitreal ziv Aflibercept injection may be effective in causing resolution of persistent sub or intraretinal fluid despite previous treatment with bevacizumab or ranibizumab by counteracting the effect of both VEGF-A and placental growth factor, with increased binding affinity. At the very least, being as effective as previous treatment but with fewer treatments.
