Eligibility Criteria
Inclusion
- Age ≥18 years at time of signing informed consent form (ICF)
- Documented diagnosis of diabetes mellitus (Type 1 or Type 2)
- Glycated haemoglobin (HbA1c) level of ≤10% within 2 months prior to screening or at screening
- Study eye
- Macular thickening secondary to DME involving the center of the fovea with CST ≥325 micrometer (µm) on SD-OCT at screening
- BCVA score of 78 to 25 letters (20/32 to 20/320 approximate Snellen equivalent)
Exclusion
- High-risk PDR
- Active intraocular inflammation (grade trace or above)
- Suspected or active ocular or periocular infection of either eye
- Uncontrolled ocular hypertension or glaucoma and any such condition the investigator determines may require a glaucoma-filtering surgery during a patient's participation in the study
- Cerebrovascular accident or myocardial infarction within 6 months prior to randomization
- Atrial fibrillation diagnosis or worsening within 6 months prior to randomization
- Uncontrolled blood pressure
- Substudy:
- Inclusion Criteria:
- Having experienced a septum dislodgement in the original implant while in the main study or after exiting the main study
- Sufficiently clear ocular media and adequate pupillary dilation to allow for analysis and grading by central reading center
- Exclusion Criteria (Cohort 1 Only):
- Recent history (in the last 3 months prior to enrollment) of other disease, other non-diabetic metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a condition that contraindicates the use of ranibizumab or surgical placement of the PDS implant; that might affect interpretation of the results of the study; or that renders the participant at high risk for treatment complications
- Active cancer within the last 12 months, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or prostate cancer
- Current systemic treatment for a confirmed active systemic infection
- Participation in an investigational trial that involves treatment with any drug or device (with the exception of vitamins and minerals or enrollment in Study GR40550) within 6 months prior to enrollment
- Use of antimitotic or antimetabolite therapy within 30 days
- Ocular Exclusion Criteria for Study Eye:
- Any ocular condition that may render the participant at high risk for surgical or treatment complications
- Intraocular surgery (including cataract surgery) within 1 month preceding the enrollment visit
- Any use of medicated intraocular implants (other than the PDS implant), at any time prior to enrollment
- History of rhegmatogenous retinal tears or peripheral retinal breaks within 3 months prior to the enrollment visit
- Any concurrent ocular condition that would require surgical intervention during the study to prevent or treat visual loss
- Concurrent conjunctival, tenon's capsule, and/or scleral condition in the supero-temporal quadrant of the eye (e.g., scarring, thinning, mass) that may affect the refill-exchange procedure of the PDS implant
- Ongoing ocular complications that might affect participant safety Ocular Exclusion Criteria for Either Eye
- Suspected or active ocular or periocular infection (e.g., infectious conjunctivitis or endophthalmitis)
- Any history of uveitis
- Active blepharitis
