Brief Summary

This study will evaluate the efficacy, safety, and Pharmacokinetics (PK) of the PDS with ranibizumab in participants with DME when treated every 24 weeks (Q24W) compared with intravitreal (IVT) ranibizumab 0.5 milligrams (mg) every 4 weeks (Q4W). The substudy will evaluate safety of re-implanting the updated PDS with ranibizumab and the refill-exchange procedures following re-implantation in participants with DME who were previously enrolled in the main study, GR40550. Up to 100 participants from the main study will be enrolled and followed for a maximum of 72 weeks post-re-implantation in the substudy.
