ETDRS-DRSS classifies diabetic retinopathy (DR) into 12 severity steps ranging from absence of retinopathy to advanced proliferative diabetic retinopathy (PDR). DRSS grades= 10 (DR absent) - 85 (very advanced PDR), DRSS 90 = ungradable. All DRSS values are converted into a 12-level scale, from 1 (DR absent) to 12 (very advanced PDR), allowing derivation of ≥2-step change from baseline for post-baseline assessment. A lower score represents less advanced diabetic retinopathy. The Cochran-Mantel Haenszel (CMH) method was used for analysis and weighted percentage of participants are estimated and reported in this outcome measure. Participants receiving supplemental treatments, prohibited therapy, or panretinal photocoagulation (PRP) were considered non-responders. Missing values not preceded by these intercurrent events were imputed using the last observation carried forward method. SD OCT= spectral-domain optical coherence tomography.

ITT Population included all participants who were randomized. Participants were grouped according to treatment assigned at randomization.

A vision threatening complication is defined as proliferative DR (PDR) or anterior segment neovascularization (ASNV) or center-involved diabetic macular edema (CI-DME). CI-DME is defined as central foveal thickness (CST) ≥325 micrometres (μm) on spectral-domain optical coherence tomography (SD-OCT). Composite strategy (i.e., considered to be an event) was applied to participants who received supplemental or prohibited therapy or PRP in the study eye. The rate of participants was calculated using the Kaplan-Meier (KM) method.

BCVA was measured at a starting test distance of 4 meters using a set of three Precision Vision^TM or Lighthouse distance acuity charts (modified ETDRS Charts 1, 2, and R). The BCVA letter score ranges from 0 to 100 (best score attainable), and a higher score indicates better visual acuity.

BCVA is measured using the ETDRS visual acuity chart starting at a test distance of 4 meters. The number of letters read correctly, Snellen fraction are converted to a decimal scale. There are 11 lines on a standard Snellen chart ranging from 0.1 (20/200) at worst to 2.0 (20/10) at best. 20/20 on the decimal scale is equal to 1.0. The higher the number of letters read correctly (higher number on the decimal scale), the better the vision (or visual acuity). The Snellen equivalent of 20/40 or better is 69 or more letters correctly read in the ETDRS chart.

CST is defined as the average thickness of the central 1 millimeter (mm) circle of the ETDRS grid centered on the fovea measured between the internal limiting membrane and the Bruch's membrane. CST is measured using spectral domain optical coherence tomography (SD-OCT). A central reading center graded the SD-OCT digital images. A negative change from baseline value represents a reduction in macular edema.

Total macular volume in cubic millimeter (mm^3), is the calculated volume from the layers of the retina based off OCT imaging. TMV is measured using SD-OCT.

An adverse event is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product,regardless of causal attribution.An adverse event can therefore be any unfavourable & unintended sign,symptom,or disease temporally associated with the use of a pharmaceutical product,whether considered related to the pharmaceutical product.Preexisting conditions which worsen during a study are also considered as adverse events.Ocular AEs are the events which are localized in the ocular region,graded according to the AE Severity Grading Scale as Mild:discomfort noticed,but no disruption of normal daily activity;Moderate:Discomfort sufficient to reduce or affect normal daily activity;Severe incapacitating with inability to work or to perform normal daily activity.Number of participants with ocular AEs in the study eye are reported in this outcome measure.As prespecified in the protocol, this outcome measure was applicable to participants in the PDS arm only.

The numbers of ADA-positive participants at baseline and after drug administration were to be summarized for participants exposed to Ranibizumab. PDS patients who were ADA positive at the reference visit and ADA titer increased after implant; in this case, the titer of one or more samples collected after implant must be at least 4-fold greater than the titer of the reference visit sample. These patients are considered to have treatment-enhanced ADA responses.

The numbers of neutralizing antibodies positive participants at baseline and after drug administration were to be summarized for participants exposed to Ranibizumab.

An AE related to study device or procedure is defined as any adverse event related to the use of an investigational medical device.

The PPPQ is a 3-item questionnaire that captures a participant's preference for treatment (PDS or intravitreal injections), the strength of their preference (very strong, fairly strong, and not very strong) and the reasons for their preference (less worry or nervousness, requires less time for treatment, less discomfort, fewer treatments and other reason).
