入选标准
- •Signed informed consent prior to participation in the study.
- •Type 1 or 2 diabetes mellitus and HbA1c of ≤12%.
- •DR in the Study Eye (DRSS as determined by the reading center based on color fundus photographs), who have not previously received intravitreal medications for DR or DME, and in whom pan-retinal photocoagulation (PRP) can be safely deferred for at least 6 months per the Investigator.
- •CST ≤320 microns and a BCVA ETDRS letter score in the Study Eye of ≥69 letters (approximate Snellen equivalent of 20/40 or better) in the Study Eye at screening and confirmed at Day 1; OR
- •CST >320 and ≤350 microns and a BCVA ETDRS letter score in the Study Eye of ≥79 letters (approximate Snellen equivalent of 20/25 or better) in the Study Eye at screening and confirmed at Day 1.
排除标准
- •Prior PRP in the Study Eye.
- •Current anterior segment neovascularization (ASNV), vitreous hemorrhage, or tractional retinal detachment in the Study Eye.
- •Prior intravitreal anti-VEGF treatment in the Study Eye for DR or DME within the last twelve (12) months prior to Day
- •Prior intravitreal or periocular steroid in the Study Eye for DR or DME within the last twelve (12) months prior to Day
- •Prior use of an investigational intravitreal treatment for DR or DME in the Study Eye.
- •History of vitreoretinal surgery in the Study Eye.
- •History of uveitis in either eye.
- •Cataract in the Study Eye that in the judgment of the Investigator is expected to require surgical extraction within 12 months of screening.
- •Significant media opacities, including cataract, in the Study Eye that might interfere with visual acuity, assessment of safety, OCT, or FP.
- •Any history or evidence of a concurrent ocular condition present in the Study Eye, that in the opinion of the Investigator could require either medical or surgical intervention or alter visual acuity during the study.
- •Active or suspected ocular or periocular infection or inflammation.
- •Women who are pregnant or lactating or intending to become pregnant during the study.
- •History of a medical condition that, in the judgment of the Investigator, would preclude scheduled study visits, completion of the study, or a safe administration of investigational product.
- •Recent history (within the 6 months prior to screening) of myocardial infarction, stroke, transient ischemic attack, acute congestive heart failure or any acute coronary event.
- •Uncontrolled blood pressure defined as a systolic value ≥ 180 mmHg or diastolic value ≥ 100 mmHg while at rest.
- •Other protocol-specified exclusion criteria may apply.
