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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

* Any current ocular condition for which visual acuity loss would not improve from resolution of macular edema in the study eye
* History of rhegmatogenous retinal detachment in the study eye
* Any current or history of ocular disease other than nAMD in the study eye that may confound assessment of the macula or affect central vision
* History of the following therapies in the study eye:
