E.1.1 | Medical condition(s) being investigated |
Diabetic Macular Oedema (DME) |

E.1.1.1 | Medical condition in easily understood language |
Diabetic macular oedema is a swelling in the light-sensitive tissue in the back of the eye (called the retina) in people with diabetes, caused by leaking of blood vessels. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the study is to select the THR-149 dose and to assess the difference in treatment effect between THR-149 and aflibercept in terms of increase in best corrected visual acuity (BCVA) from Baseline at Month 3.
|
|
E.2.2 | Secondary objectives of the trial |
• To assess the efficacy of 3 monthly intravitreal injections of THR-149 over-time
• To assess the safety of 3 monthly intravitreal injections of THR-149 over-time |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Written informed consent obtained from the subject prior to screening procedures

|
E.4 | Principal exclusion criteria |
