Eligibility Inclusion Criteria: - 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. - Safe to withhold treatment of the study eye with laser photocoagulation, intravitreal steroid injection, or intravitreal vascular endothelial growth factor (VEGF) inhibitor for the duration of the study. - Body weight greater than equal to (>=) 50 kilograms (kg) and Body mass index (BMI) within the range 18 to 43 kg per square meter (inclusive) at screening. - Male participants must agree to refrain from donating sperm, plus either be abstinent from heterosexual or homosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent or must agree to use acceptable contraception/barrier to use acceptable contraceptive methods if their partner is of childbearing potential. This criterion must be followed from the first dose of study treatment until the follow-up visit. - A female participant is eligible to participate if she is not of childbearing potential. Exclusion Criteria: - Additional eye disease in the study eye that in the opinion of the Investigator could compromise assessment. - History of choroidal neovascularization in the study eye, or current choroidal neovascularization in the fellow eye requiring treatment. - Active Proliferative diabetic retinopathy (PDR) in the study eye or untreated active PDR in the fellow eye. - Ischemic maculopathy on fluorescein angiography. - Intraocular surgery or laser photocoagulation in the study eye within 90 day. - Use of intravitreal ranibizumab,or bevacizumab within 42 days (6 weeks), or aflibercept within 56 days (8 weeks) of dosing in the study eye. - Use of intraocular steroids in the study eye within 180 days of dosing. - Use of or expected need for intravitreal or intraocular treatment in the study eye during course of the study. - Use of any systemically administered anti-angiogenic agent within 6 months of dosing. - Evidence of vitreomacular traction as determined by the Investigator. - Uncontrolled intraocular pressure in the study eye despite treatment with glaucoma medication. - Within 6 months prior to the Screening Visit, use of medications known to be toxic to the retina, lens or optic nerve - Uncontrolled diabetes as indicated by glycated hemoglobin (HbA1c) >12% at Screening. - Active ulcer disease or gastrointestinal bleeding by history within 6 months of screening or by exam at the time of screening. - Certain type of liver disease. - Participant who, in the Investigator's opinion, poses a significant suicide risk. - History or current evidence of any serious or clinically significant cardiac, gastrointestinal, renal, endocrine, neurologic, hematologic, infectious or other condition that is uncontrolled. - Corrected (QTc) interval >450 milliseconds (msec) or QTc >480 msec in participants with bundle branch block. - Use of certain medications that may interfere with the study medication or eye assessments (these will be identified by the study doctor). - Current enrollment, or recent participation in a study of investigational intervention or medical research. - Sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the Investigator or Medical Monitor, contraindicates participation in the study. - Any other reason the investigator deems the participant should not participate in the study. - Other protocol-defined inclusion/exclusion criteria may apply.
