A Phase 2, Multicenter, Randomized, Parallel Study to Evaluate the Efficacy and Safety of Two Doses of ENN0403 in Subjects with Diabetic Macular Edema (DME)
This is a multicenter, randomized, parallel study to evaluate the efficacy and safety of two doses of ENN0403 in subjects with diabetic macular edema (DME). Approximately 60 subjects will be randomized to receive ENN0403 capsule orally once a day at the low dose or high dose with a 1:1 ratio. The study period consisted of up to 2 weeks of screening, 12 weeks of treatment and 2 weeks of follow-up, and the entire trial period was up to 16 weeks.
• Provide written informed consent;
• Aware of the entire study process and requirements, understands the importance of medication compliance and completing all assessments on time throughout the study, and agrees to strictly follow the protocol and study procedures, including restrictions on drug combination during the study;
• Diagnosis of type 1 or type 2 diabetes mellitus and HbA1c≤10.0% with regular use hypoglycemic drugs and stable glycemic control 1 month before screening (at the discretion of the investigator);
• The decrease of BCVA is mainly caused byDiabetic Macular Edema in the study eye;
• BCVA letter score of ≤ 73 (Snellen 20/40) and ≥ 24 (Snellen 20/320) at screening visit and at baseline. If both eyes meet the inclusion criteria, the study eye will be determined by the investigator from a medical perspective. ( If both eyes meet the inclusion criteria，the eye with poor baseline vision will be selected as the study eye; If the BCVA number is the same, choose the eye with the thicker CRT as the study eye) ；
• Optical Coherence Tomography (OCT) foveal CRT at screening measuring ≥300 μm.
