Adverse Events

This study is an open-label, dose-escalating, 48-week study assessing the safety, tolerability, bioactivity and duration of action of a single intravitreal injection of 0.1 mg, 0.25 mg, or 0.5 mg AXT107 in approximately 18 subjects (up to 6 subjects per dose) with Diabetic Macular Edema (DME).

Upon providing informed consent, subjects will be sequentially enrolled into the study. Decision regarding dose escalation will be based on the recommendation from the Data Monitoring Committee (DMC). The first 3 eligible subjects will receive the low dose of AXT107 injection. After the 3 low dose subjects complete a 7-day follow-up, the DMC will review their safety data. If an acceptable safety profile is determined by the DMC, 3 additional subjects will be enrolled to receive the mid dose of AXT107 injection. Upon completion of a 7-day follow-up, review of the safety data, and determination of an acceptable safety profile by the DMC for the mid dose subjects, 3 additional subjects will be enrolled to receive the high dose of AXT107 injection.
