E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objective : To evaluate the efficacy of EG-Mirotin at doses 1mg and 2mg versus placebo on diabetic macular edema in diabetic retinopathy patients after 5 daily subcutaneous injections. Anatomical efficacy will be assessed by the measurement of central subfield retinal thickness (CSF Thickness) and retinal volume using Spectral Domain-Optical Coherence Tomography (SD-OCT). |
|
E.2.2 | Secondary objectives of the trial |
Secondary objective : To evaluate functional efficacy (visual acuity assessed by ETDRS charts) To evaluate reduction in vascular permeability using measurement of vascular leakage at the time of fluorescein angiography To evaluate the safety and tolerability of multiple administered dose of EG-Mirotin. To evaluate the pharmacokinetic of EG-Mirotin at doses 1mg and 2mg after 5 daily subcutaneous administrations. |

Best-corrected ETDRS visual acuity letter score between ≥ 79 (approximate Snellen equivalent 20/30 or better) and 24 (approximately 20/320), 13. Non proliferative retinopathy or inactive proliferative retinopathy treated by panretinal photocoagulation dating more than 6 months 14.

E.4 | Principal exclusion criteria |
1. Presence or history of protein drug hypersensitivity, or allergic disease diagnosed and treated by a physician. 2. Allergy to fluorescein 3. Patients who are pregnant or breastfeeding. Patients should not be enrolled if they plan to become pregnant during the time of study participation. 4. Any drug intake during the last month prior to the first administration except those defined in Section 5.3. 5. Use of anti-platelets drugs 6. Intensive insulin treatment (a pump or more than 3 daily injections) 7. Edema is considered to be due to a cause other than diabetic edema for the chosen eye, especially vitreoretinal interface abnormalities within 1 disc diameter of the fovea (e.g., a taut posterior hyaloid or epiretinal membrane). 8. An ocular condition is present resulting visual acuity would not improve from resolution of edema, at the discretion of the investigator (e.g. foveal atrophy, pigmentary changes, dense subfoveal hard exudates, nonretinal condition) for the chosen eye. 9. An ocular condition is present (others than diabetes) that, in the opinion of the investigator, might affect edema or alter visual acuity during the course of the study (e.g. vein occlusion, uveitis, or other ocular inflammatory disease, neovascular glaucoma…). 10. Substantial cataract that, in the opinion of the investigator, is likely to be decreasing visual acuity by 3 lines (i.e. cataract would be reducing acuity to 20/40 or worse if eye was otherwise normal) for the chosen eye. 11. Prior history of intravitreal or peribulbar injections of triamcinolone acetonide or vitrectomy, intravitreal injection of anti-VEGF treatment within the prior 4 months, 12. Prior history of yttrium–aluminum–garnet capsulotomy within the prior 2 months. 13. History of major ocular surgery (cataract or glaucoma surgery, pars plana vitrectomy) in the study eye within prior 4 months or anticipated within the next 4 months following randomization. 14. Prior focal photocoagulation within 4 months before administration 15. Prior panretinal scatter photocoagulation within 6 months before administration or need for a panretinal scatter photocoagulation within the next 4 months (severe pre proliferative diabetic retinopathy or proliferative diabetic retinopathy) 16. Active neovascularization of the disc, retina, iris, or angle, vitreous haemorrhage or tractional retinal detachment for the chosen eye 17. Macular ischemia (>grade 2) on fluorescein angiography 18. General anesthesia within 3 months before administration. 19. Major surgery within 28 days prior to randomization or major surgery planned during the next 6 months. 20. Positive HBs antigen or anti HCV antibody, or positive results for HIV 1 or 2 tests. 21. Significant renal disease, defined as a history of chronic renal failure requiring dialysis or kidney transplant, calculated creatinine clearance ≤ 60 mL/min. 22. Blood donation (including in the frame of a clinical trial) within 2 months before administration. 23. Patient who, in the judgment of the Investigator, is likely to be non-compliant or uncooperative during the study, or unable to cooperate because of a language problem, poor mental development. 24. Medical history which in the opinion of the investigator would make the patient unsuitable for participation in the study (including, but not limited, to patients with coronary insuffiency, thromboembolism diseases) . 25. Patient in the exclusion period of a previous study. 26. Patient who cannot be contacted in case of emergency 27. Patient under administrative or legal supervision
