- At least 18 to 75 years of age inclusive, at the time of signing the informed consent.
- Diagnosis of diabetes mellitus (type 1 or type 2).
- Confirmation of DME with center involvement in at least one eye by fluorescein angiography.
- Confirmation of retinal thickening (diabetic macular edema) involving the center of the fovea in the study by Investigator.
- Best Corrected Visual Acuity (BCVA) letter score of 80 letter or worse (Snellen equivalent: equivalent to 20/25) or worse in the study eye.
