NCT03939767

Brief Summary

In this observational study researchers want to learn more about changes in visual acuity (clarity of vision) with proactive flexible treatments over time in patients suffering from wet age-related macular degeneration (wAMD) after decision to treat with Aflibercept (Eylea) was made. Wet AMD is an eye disease that progressively destroys the macula, the central portion of the retina, impairing central vision.

Outcome Measures

Primary Outcomes (1)

  • The change in BCVA (best corrected visual acuity)

    In treatment-naïve wAMD patients treated with IVT aflibercept in a flexible proactive treatment pattern (fixed dosing or T\&E (Treat and Extend Regimen)) by label regimen.

    Baseline to 12 months

Secondary Outcomes (7)

  • The change in BCVA

    Baseline to 24 and 36 months

  • The change in BCVA by intended treatment regimen

    Baseline to 12, 24 and 36 months

  • The proportion of patients (eyes) gaining or losing a visual acuity compared to baseline

    Baseline at 12, 24 and 36 months

  • The proportion of patients (eyes) achieving a Snellen equivalent of 20/40 or better (approximately 73 ETDRS letters)

    At 12, 24 and 36 months

  • The changes in central retinal thickness (CRT)

    Baseline to 12, 24 and 36 months

  • +2 more secondary outcomes

Study Arms (1)

wAMD patients

Patients with a diagnosis of wAMD and naïve to any treatment in the study eye will be enrolled after the decision by treating physician for IVT aflibercept therapy according to the local label.

Drug: Aflibercept (Eylea, BAY86-5321)

Interventions

As prescribed by the treating physician according to the local label. No IVT aflibercept will be provided due to a nature of observational study.

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Approximately 2.000 patients from sites in Asia-Pacific, Europe, Latin America and North America.

You may qualify if:

  • A diagnosis of wAMD.
  • Patients for whom the decision to initiate treatment with IVT aflibercept in a proactive regimen was made as routine clinical practice.
  • Treatment-naïve in the study eye (no prior therapy for wAMD).
  • Patient age ≥50 years of age.
  • Written informed patient consent before the start of data collection (according to the requirements of the local authorities and laws).

You may not qualify if:

  • Participation in an investigational program with interventions outside of routine clinical practice.
  • Patients with contraindications to IVT aflibercept listed in the local marketing authorization.
  • Planned treatment regimen outside of the local marketing authorization.
  • Patients with eye diseases, e.g. advanced glaucoma or visually significant cataracts, likely to require surgery during the observation period in the study eye.
  • Concomitant ocular or systemic administration of drugs up to 3 months before IVT aflibercept treatment that could interfere with or potentiate the mechanism of action of IVT aflibercept, including other anti-VEGF agents in the fellow eye.
  • Any other retinal disease which may interfere with the treatment of wAMD.
