简要总结
This is an observational study to will evaluate and compare two Ranibizumab treatment regimens (Standard of care) in patients with neovascular (wet) age-related macular degeneration (wAMD) aiming to achieve and to maintain a maximum visual function benefit. The results will be used to generate further recommendations on the timing of treatment administration for patients with neovascular (wet) age-related macular degeneration (wAMD). In this context, the study will use the anatomical imaging (for example, optical coherence tomography [OCT]) to evaluate wAMD disease activity impacted by the recurrence of disease instability and for decision making in the treatment decision algorithm.

结局指标
主要结局
Mean Change in Visual Acuity
时间窗: Baseline to Month 12
Visual Acuity (VA) will be assessed using best correction determined from protocol refraction during screening and every 3 months throughout the study; in the monthly regimen and during screening and at every visit thereafter throughout the study in the treat and extend regimen. VA measurements (number of letters correctly identified) will be performed with the patient in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like VA testing charts at an initial testing distance of 4 meters. This outcome measure will describe the difference in the VA mean changes between the two regimens from Baseline to Month 12.
次要结局
- Proportion of patients with a loss of less than 5, 10, and 15 letters between the 2 treatment arms.(baseline to Month 24)
- Mean change in BCVA ETDRS between the 2 treatment arms at Month 12 compared to Month 3.(Month 12 and Month 3)
- Mean change in BCVA ETDRS between the 2 treatment arms.(Baseline to Month 24)
- Proportion of patients with a gain of equal or more than 5, 10, and 15 letters between the 2 treatment arms.(Baseline to Month 24)
- Proportion of patients with a loss of less than 5, 10, and 15 letters between the 2 treatment arms from baseline to Month 12 and from baseline to Month 24.(baseline to Month 12)
- Number of injections performed in each treatment arms.(Month 12 to Month 24)
