- •Hemoglobin (HbA1c) value =< 11%
- •The study eye must meet the following criteria
- •Diabetic macular edema with central fovea involvement and visual impairment in subjects;
- •Best corrected visual acuity letter score (ETDRS)>= 19 (i.e., 20/400 or better) and <= 73 (i.e., 20/40 or worse)in the study eye;
- •CRT ≥ 275 μm;
- •No optometric media opacity and pupil shrinkage.
- •Best corrected visual acuity letter score (ETDRS) > =24 (i.e., 20/320 or better)in the fellow eyes
排除标准
- •Any eye has active ocular infections (e.g.,blepharitis, keratitis, scleritis, conjunctivitis);
- •The study eye has proliferative diabetic retinopathy (PDR), except for the PDR with regression after panretinal photocoagulation, and Inactive, fibrotic PDR
- •History of vitreous hemorrhage in the study eye within 2 months before screening
- •Structural retinal damage with fovea in the study eye (e.g. retinal pigment epithelium(RPE) atrophy, retinal fibrosis, laser scarring, dense hard exudation), or researchers believe that the study eye has other retinal damage that may hinder visual improvement after macular edema subsides
- •In addition to diabetic retinopathy, there are other causes of macular edema or visual changes in the study eye.
- •Ophthalmic conditions (e.g.,retinal vein occlusion (RVO) Choroidal neovascularization, retinal detachment, macular hole, retinal traction in macular region, epiretinal membrane, etc.)
- •Iris neovascularization in the study eye;
- •Uncontrollable glaucoma in the study eye (defined as intraocular pressure after antiglaucoma medication>= 25 mm Hg), or glaucoma filtering surgery history;
- •Researchers believe that cataract in the study eye may affect the judgement of examination or test results, or surgical treatment is required in 6 months following screening
- •The study eye has no lens( except intraocular lens)
- •History of Intraocular injection for corticosteroids (e.g. triamcinolone) at any time in the past 3 months, or corticosteroids injection around the eyes within one month before screening
- •History of vitrectomy in the studyeye
- •History of panretinal photocoagulation in the study eye in the past 6 months before screening; or panretinal photocoagulation may be required following screening
- •Study eye have received more than two local/grid retinal photocoagulation treatments, or history of local/grid retinal photocoagulation treatments in the study eye in the past 3 months before screening
- •History of anti-VEGF drugs treatments(e.g. Abercept, Pigatani Sodium, Razumab, Bevacizumab, etc.) in any eye or system within 3 months before screening;
- •History of any intraocular surgery (e.g. cataract surgery, YAG posterior capsulotomy, etc) in the study eye within 3 months before screening;
- •History of ophthalmic surgery involving macular areas (e.g. PDT, macular transposition) in the study eye, except for local/grid retinal photocoagulation
- •Any of the following general condition are present:
- •Uncontrolled blood pressure control (defined as systolic blood pressure > 150 mmHg or diastolic pressure > 95 mmHg after antihypertensive medication
- •The subjects is suffering from systemic infections and requiring oral, intramuscular or intravenous medication
- •History of stroke, transient ischemic attack, myocardial infarction or acute congestive heart failure in the past 6 months before screening;
- •Medicines with toxicity to the lens, retina or optic nerve (deferoxamine, chloroquine,hydroxychloroquine (chloroquine), tamoxifen and phenol etc.) is being used or may be used during the study period
- •Diagnosed systemic immune diseases (e.g. ankylosing spondylitis and systemic lupus erythematosus etc.), or any uncontrolled clinical problem (e.g. AIDS, malignant tumors, active hepatitis, serious mental, neurological, cardiovascular, respiratory and other systemic diseases, etc.)
- •History of allergy to fluorescein sodium and allergies to protein products for treatment or diagnosis, history of allergy to more than two drugs and/or non-drug factors, or suffering from allergic diseases now
- •Any of the following laboratory tests abnormalities:
- •Diabetic patients with uncontrolled blood glucose (fasting blood glucose >= 8.8 mmol/L);
- •Renal function impairment (Cr is 1.5 times higher than the upper limit of normal values in the local laboratory) Liver dysfunction (ALT or AST is 2 times higher than the upper limit of normal value in the local laboratory).
- •Abnormal coagulation function (prothrombin time >= the upper limit of normal value for 3 seconds) and activated partial thromboplastin time >= the upper limit of normal value for 10 seconds)
- •Patients with childbearing age with any of the following conditions:
- •Those who do not use effective contraceptive measures;
