Study Endpoints
Primary Endpoints
Number of Participants With Adverse Events
Adverse events are reported from first dose of study treatment until end of study treatment plus 12 weeks post treatment, up to a maximum timeframe of approximately 24 weeks (approximately 168 days).

An AE is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a patient or clinical investigation patient. The severity of the AEs (mild, moderate, severe) was based on the Common Terminology Criteria for Adverse Events (CTCAE). Number of participants in each category is reported in the table. A participant who falls multiple times in one category is counted only once.

Number of Participants With Ocular Adverse Events by Preferred Term in Study Eye
Adverse events are reported from first dose of study treatment until end of study treatment plus 12 weeks post treatment, up to a maximum timeframe of approximately 24 weeks (approximately 168 days).

An AE is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a patient or clinical investigation patient.

Number of Participants With Non-ocular Adverse Events (>=2%)
Adverse events are reported from first dose of study treatment until end of study treatment plus 12 weeks post treatment, up to a maximum timeframe of approximately 24 weeks (approximately 168 days).

An AE is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a patient or clinical investigation patient.

Intraocular Pressure (IOP) in Study Eye
Screening, and Day 85

Intraocular pressure was measured per the study site's regular practice.

Best Corrected Visual Acuity (BCVA) by Early Treatment Diabetic Retinopathy Study (ETDRS) Visual Acuity Charts in Study Eye
Days 2, 8, 15, 29, 43, 57, and 85

BCVA was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts. Visual function of the study eye was assessed using the ETDRS protocol. BCVA in study eye was analyzed with a mixed model for repeated measures. The model included treatment, visit, and the treatment by visit interaction as independent variables. An unstructured residual covariance structure was used. Baseline BCVA value and treatment naïve and treatment experienced variable were used as covariates. Min and max possible scores are 0-100 respectively. A higher score represents better visual functioning.

Inner Macular Thickness (Inferior)
Week 12 (Day 85)

Macular thickness was measured by spectral domain optical coherence tomography (SD-OCT).

Inner Macular Thickness (Temporal)
Week 12 (Day 85)

Macular thickness was measured by spectral domain optical coherence tomography (SD-OCT).

Outer Macular Thickness (Inferior)
Week 12 (Day 85)

Macular thickness was measured by spectral domain optical coherence tomography (SD-OCT).

Outer Macular Thickness (Temporal)
Week 12 (Day 85)

Macular thickness was measured by spectral domain optical coherence tomography (SD-OCT).

Number of Participants Without Changes in Foveal Avascular Zone as Measured by Fluorescein Angiography (FA) in Study Eye
Days 29, 57, 85, End of Study (Up to Day 140)

Foveal avascular zone was assessed by fluorescein angiography (FA).

Mixed Model Repeated Measures Analysis of Ratio to Baseline in Central Subfield Retinal Thickness (CSFT) in the Study Eye
Days 8, 15, 29, 43, 57, 85

Central subfield thickness was measured by spectral domain optical coherence tomography (SD-OCT). Central subfield retinal thickness was analyzed with a mixed model for repeated measures. The model included treatment, visit, and the treatment by visit interaction as independent variables. An unstructured residual covariance structure was used. Log-transformed baseline central subfield retinal thickness and treatment naïve and treatment experienced variable were used as covariates. Results were back-transformed to show results as a ratio to baseline.
