入选标准
- •Adults ≥ 18 years with type 1 or 2 diabetes mellitus
- •Subjects with diabetic macular edema (DME) secondary to diabetes mellitus involving the center of the macula in the study eye
- •Decrease in vision determined to be primarily the result of DME in the study eye
- •Best-corrected visual acuity (BCVA) early treatment diabetic retinopathy study (ETDRS) letter score of 73 to 24 (20/40 to 20/320) in the study eye
排除标准
- •Laser photocoagulation (panretinal or macular) in the study eye within 90 days of Day 1
- •More than 2 previous macular laser treatments in the study eye
- •Previous use of intraocular or periocular corticosteroids in the study eye within 120 days of Day 1
- •Previous treatment with antiangiogenic drugs in either eye (pegaptanib sodium, bevacizumab, ranibizumab etc.) within 90 days of Day 1
- •Active proliferative diabetic retinopathy (PDR) in the study eye
- •Uncontrolled diabetes mellitus, as defined by HbA1c >12%
- •Only 1 functional eye even if that eye is otherwise eligible for the study
结局指标
主要结局
Change From Baseline in Best Corrected Visual Acuity (BCVA) as Measured by Early Treatment Diabetic Retinopathy Study (ETDRS) Letter Score at Week 52 - Last Observation Carried Forward (LOCF)
时间窗: Baseline up to week 52
Visual function of the study eye was assessed using the ETDRS protocol, which is a widely accepted international standard for macular laser photocoagulation treatment. A higher score represents better functioning. LOCF censored measurements after additional treatment.
次要结局
- Change From Baseline in National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) Near Activities Subscale at Week 52 - LOCF(Baseline up to week 52)
- Change From Baseline in National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) Distance Activities Subscale at Week 52 - LOCF(Baseline up to week 52)
- Percentage of Participants Who Gained at Least 10 Letters in BCVA as Measured by ETDRS Letter Score Compared With Baseline at Week 52 - LOCF(Baseline up to week 52)
- Percentage of Participants Who Gained at Least 15 Letters in BCVA as Measured by ETDRS Letter Score Compared With Baseline at Week 52 - LOCF(Baseline up to week 52)
- Percentage of Participants With a Greater Than Equal (>=) Two-step Improvement From Baseline in the ETDRS Diabetic Retinopathy Severity Score (DRSS) as Assessed by Fundus Photography (FP) at Week 52 - LOCF(Baseline up to week 52)
- Change From Baseline in Central Retinal Thickness (CRT) at Week 52 as Assessed on Optical Coherence Tomography (OCT) - LOCF(Baseline up to week 52)
