Real-World Study of Intravitreal Aflibercept 8 mg in Pretreated Eyes With nAMD or DME

Sponsor: Grupo de Estudos da Retina

View on ClinicalTrials.gov

Summary

The goal of this multicentre observational study is to evaluate the interval-extension potential, effectiveness, and safety of intravitreal aflibercept 8 mg in pretreated eyes with neovascular age-related macular degeneration (nAMD) or diabetic macular oedema (DME) under routine clinical practice in Portugal. It consists in an ambidirectional longitudinal cohort with retrospective collection of pre-switch clinical and treatment history and prospective follow-up after initiation of intravitreal aflibercept 8 mg in routine clinical practice. The main questions it aims to answer are: \- Can treatment intervals be extended after switching to intravitreal aflibercept 8 mg while maintaining disease control in pretreated eyes with nAMD or DME? What are the functional, anatomical, and safety outcomes associated with intravitreal aflibercept 8 mg in routine clinical practice? Participants are adults with nAMD or DME who have previously received intravitreal treatment and are switched to aflibercept 8 mg as part of routine clinical care. No study-specific interventions or procedures are performed. Clinical data are collected prospectively through the Portuguese national Retina.PT registry during routine follow-up visits, including treatment patterns, injection intervals, visual acuity, retinal anatomical assessments, and ocular and systemic safety outcomes.

Aflibercept 8mg

Intravitreal aflibercept 8 mg administered as part of routine clinical practice according to the locally approved prescribing information.
