入选标准
- •1. History of diabetes mellitus (Type 1 or Type 2).
- •2. Serum HbA1c =5.5% and =12% at the screening visit.
- •3. Subjects with diabetic macular edema affecting the fovea consisting of retinal
- •thickness on OCT measuring 275 µm or more in the central subfield at the screening
- •4. Reduced visual acuity resulting from retinal thickening involving the center of the
- •fovea and a best corrected visual acuity, using Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity protocol of 20/40 or worse (letter score of
- •=73) and up to 20/320 or better (letter score =24) in the study eye at the screening
- •5. Visual acuity score in the fellow eye of 20/400 or better (letter score of =19) at the
- •screening visit. Note: Only one eye will be treated (study eye), in the event both eyes are eligible for study entry the study eye should be selected by the investigator and subject.
- •6. Treatment for diabetic macular edema with laser photocoagulation can be withheld
- •for at least 90 days after the subject has enrolled in the study.
- •7. Ocular media and adequate pupillary dilation to allow good quality OCT and
- •stereoscopic fundus photography.
- •8. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
- •9. Subjects who are willing and able to comply with scheduled visits, treatment plan,
- •laboratory tests, and other study procedures such as telephone access from Call
- •Center for the administration of NEI-VFQ-25.
- •Note: Because the questionnaire or certified interviewers may not be available in all local languages needed, certain countries or sites or individuals will be exempt from this requirement (with prior approval from the sponsor). Those countries/sites/individuals impacted will be identified in a note to file.
- •10. Males and females aged 18 years or older. Female subjects either of non-childbearing potential (hysterectomized or believed to be post-menopausal as evidenced by a 3 year history of amenorrhea) or of childbearing potential are eligible, provided they have a negative urine pregnancy test at the Screening and Baseline visit. Female subjects of childbearing potential should be willing to use adequate (at least two forms of) contraceptive methods as described below during the treatment period and for 3 months after the last dose of study medication. Male subjects with partners of childbearing potential must agree to use adequate (at least one form of) contraception as described below during the treatment period and for 3 months after the last dose of study medication or be surgically sterile.
- •Acceptable contraceptive methods for female (need at least two):
- •a. Hormonal methods of contraception (including oral and transdermal
- •contraceptives, injectable progesterone, progestin subdermal implants,
- •progesterone-releasing IUDs) at least 14 days prior to the first dose of trial
- •medication;
- •b. Abstinence;
- •c. Placement of a copper-containing intrauterine device (IUD);
- •d. Condom with spermicidal foam/gel/film/cream/suppository;
- •e. Tubal ligation;
- •f. Male partner who has had a vasectomy for at least 4 months.
- •Acceptable contraceptive methods for male (need at least one):
- •a. Abstinence;
- •b. Use of condom for males with a vasectomy;
- •c. Without a vasectomy, must use a condom and be instructed that their female
- •partner should use another form of contraception such as an IUD, spermicidal
- •foam/gel/film/cream/suppository,
排除标准
- •1.Panretinal photocoagulation or macular photocoagulation performed in the study eye within 3 months of the screening visit.
- •2.Subjects receiving concomitant intravitreal anti-VEGF therapy in the non study eye. Intravitreal steroids in the non study eye are permitted.
- •3.Any concurrent intraocular condition in the study eye or previous surgery (eg, cataract, vitrectomy) that, in the opinion of the investigator, could either (a) require medical or surgical intervention during the 36-month study period to prevent or treat visual loss that might result from that condition, or (b) if allowed to progress untreated, could likely contribute to loss of at least 2 ETDRS lines of best corrected visual acuity over a 36-month period (c) may affect macular edema or reduce visual acuity during the course of the study eg, uveitis/ ocular inflammatory disease, vein occlusions, Irvine-Gass syndrome.
- •4.Cataract surgery in the study eye within 2 months prior to study enrollment.
- •5.High risk proliferative diabetic retinopathy (PDR) in the study eye. Inactive fibrosed neovascularization following pan retinal photocoagulation (PRP) laser therapy and non high risk PDR with no evidence of vitreous hemorrhage is permitted.
- •6.Current infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye.
- •7.Aphakia or absence of the posterior capsule in the study eye. Previous Yttrium Aluminum Garnet (YAG) capsulotomy performed 2 months or more prior to study entry associated with posterior intraocular lens implant is permitted.
- •8.Structural damage to the center of the macula in the study eye likely to preclude improvement in visual acuity following the resolution of macular edema, including but not limited to persistent DME involving the foveal center of more than 2 years in duration, atrophy of the retinal pigment epithelium, subretinal fibrosis, macular ischemia as defined by an enlarged foveal avascular zone (FAZ >1000µm on fundus fluorescein angiography), laser scar(s), organized hard exudative plaque, vitreomacular traction, epiretinal membrane evident on ophthalmic examination or by OCT.
- •9.Uncontrolled glaucoma (defined as intraocular pressure treatment with anti-glaucoma medications) with IOP ?30 mm Hg and/or advance disc cupping with glaucomatous visual field loss.
- •10.Subjects who have a history of any severe acute or chronic medical or psychiatric condition or laboratory abnormality that could increase the risk associated with study participation or could interfere with the interpretation of study results and, in the judgment of the investigator, could make the subject inappropriate for entry into this study; eg,;
- •History of gastrointestinal bleeding within 2 months of study enrollment;
- •Renal function insufficiency: serum creatinine >2.5 mg/dL or status post renal transplant or receiving dialysis;
- •liver function insufficiency: serum bilirubin >1.5 mg/dL, ALT >2 x ULN, AST > 2 x ULN, alkaline phosphatase > 2 x ULN;
- •History or evidence of severe cardiac disease (NYHA Functional Class III or IV) (Appendix 6), medical history of cerebral vascular accident, unstable angina, acute coronary syndrome, transient ischemic attacks, myocardial infarction, revascularization procedure within 6 months prior to screening visit, or ventricular tachyarrythmias requiring ongoing treatment;
- •History or evidence of clinically significant peripheral vascular disease such as intermittent claudication or prior amputation;
- •Stroke within 12 mo
