Brief Summary

Researchers are looking for new ways to treat diabetic macular edema (DME). In this trial, researchers want to learn if a trial medicine called MK-8748 can treat DME. An available standard (usual) treatment for DME is aflibercept. However, standard treatments such as aflibercept may not work for every person. The main goal of this trial is to learn if MK-8748 works as well as aflibercept to treat DME.
