What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye

    BCVA is measured in the study eye following each injection of OZURDEX® using the Snellen eye chart. BCVA measurements expressed in Snellen fractions are converted to logMAR units and the approximate Early Treatment Diabetic Retinopathy Study (ETDRS) letter score is based on the formula: approximate ETDRS letters=85+50 x log10 (Snellen fraction). The converted scores are "approximate ETDRS letters" to distinguish the scores from visual acuity measurements obtained using the ETDRS chart. One line on the EDTRS equals 5 ETDRS points. The lower the number of letters read correctly on the eye chart (lower number on the decimal scale) the worse the vision (or visual acuity). The higher the number of letters read correctly (higher number on the decimal scale), the better the vision (or visual acuity). A positive number change from baseline in the number of letters read means vision has improved and a negative number change from baseline means vision has worsened.

    Measured: Baseline, Week 12

Secondary outcomes (3)
  1. Percentage of Patients With an Increase of ≥2 Lines From Baseline BCVA in the Study Eye

    BCVA is measured in the study eye following each injection of OZURDEX® using the Snellen eye chart. BCVA measurements expressed in Snellen fractions are converted to logMAR units and the approximate ETDRS letter score is based on the formula: approximate ETDRS letters=85+50 x log10 (Snellen fraction). The converted scores are "approximate ETDRS letters" to distinguish the scores from visual acuity measurements obtained using the ETDRS chart. One line on the EDTRS equals 5 ETDRS points. The lower the number of letters read correctly on the eye chart (lower number on the decimal scale) the worse the vision (or visual acuity). An increase of 2 letters or more indicates an improvement in BCVA.

    Measured: Baseline, 48 Weeks

  2. Percentage of Patients With an Increase of ≥3 Lines From Baseline BCVA in the Study Eye

    BCVA is measured in the study eye following each injection of OZURDEX® using the Snellen eye chart. BCVA measurements expressed in Snellen fractions are converted to logMAR units and the approximate ETDRS letter score is based on the formula: approximate ETDRS letters=85+50 x log10 (Snellen fraction). The converted scores are "approximate ETDRS letters" to distinguish the scores from visual acuity measurements obtained using the ETDRS chart. One line on the EDTRS equals 5 ETDRS points. The lower the number of letters read correctly on the eye chart (lower number on the decimal scale) the worse the vision (or visual acuity). An increase of 3 letters or more indicates an improvement in BCVA.

    Measured: Baseline, 48 Weeks

  3. Mean Change From Baseline in Central Retinal Thickness

    Retinal thickness is assessed by optical coherence tomography (OCT) in the study eye. The retina is the light-sensitive part of the eye. OCT is a laser-based, noninvasive, diagnostic system providing high-resolution, three-dimensional images of the retina. A negative mean change from baseline indicates an improvement and a positive mean change from baseline indicates a worsening.

    Measured: Baseline, Week 24

Questions about this trial

What is this clinical trial studying?

An observational study of Macular Edema and Retinal Vein Occlusion, run by Allergan at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Jul 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye (time frame: Baseline, Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01571557, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2019.
