  • Research summary

    This study will look at an investigational drug called OPT-302 and how safe it is and how well it works in treating patients with age-related macular degeneration (AMD) . AMD results from a disease of the macula, a yellow part at the back of the eye that is responsible for sharp vision and seeing in colour. Wet AMD occurs when abnormal blood vessels grow under the macula and retina, a part of the eye that helps to see. The abnormal blood vessels leak blood and fluid, causing problems with vision.
    There are several approved medications that are used to treat wet AMD such as aflibercept. However, these medications may not work to improve vision in all patients or may not improve vision enough, and hence new treatment options are needed.
    The study will also look at how the study drug is processed by the body (called ‘pharmacokinetics’ or ‘PK’ testing).
    In this study, the study drug and aflibercept (approved medication to treat wet AMD) will be given as separate injections into the eye. To determine the potential benefits of the study drug, some participants may receive a control or dummy injection of the study drug. This will be done to assess whether there is an additional effect of the study drug when given along with an approved therapy. Participants will be assigned to one of three groups at random and receive aflibercept with or without the study drug (1:1:1 ratio).

    About 990 people from different study centres around the world are expected to take part in this study. The expected duration of participation for each participant is a little less than 2 years (about 23 months and 2 weeks). While in the study participants will have up to 27 visits to the study centre.
