What is being measured

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

Mean Average BCVA Change From Month 1 Through Month 6 to Baseline
the average of the changes in BCVA (letters) from baseline to any post-baseline visit, i.e. the mean of six differences to baseline for the six post-baseline visits at month 1 to 6. BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is pproximately 20/20. An increased score indicates improvement in acuity
Measured: Baseline, month 6

Secondary outcomes (9)

Mean BCVA Change at Month 6
The analysis was performed by an analysis of covariance (ANCOVA) model with average change in BCVA (letters) from Visit 1 through Visit 6 as dependent variable, and with the factors center, treatment and covariate baseline BCVA as predictors
Measured: Baseline, month 6
Number of Patients Gaining / Losing ≥ 15 / 10 / 5 Letters
BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is approximately 20/20. An increased score indicates improvement in acuity. This outcome assessed the number of participants who gained 15, 10 or 5 more letters of visual acuity at month 6 as compared with baseline
Measured: Baseline, 6 month
Time to Achieve a Significant Improvement ≥ 15 Letters
The time was analyzed by the Kaplan-Maier-Method, adjusting the calculation for dropouts
Measured: Baseline, month 6
Change Over Time in BCVA
The analysis was performed by an analysis of covariance (ANCOVA) model with average change in BCVA (letters) from Visit 1 through Visit 6 as dependent variable, and with the factors center, treatment and covariate baseline BCVA as predictors
Measured: Baseline, month 6
Change Over Time of the Central Retinal Thickness (CRT)
Retinal thickness was measured using Optical Coherence Tomography (OCT). The images were reviewed by a central reading center to ensure a standardized evaluation
Measured: Baseline, month 6
Changes in the Quality of Life According to the National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) Questionnaires
The VFQ-25 composite and subscale scores range from 0 to 100, a higher score indicating better functioning. The 12 subscales in the VFQ-25 are general health, general vision, ocular pain, near activities, distance activities, social function, mental health, role difficulties, dependency, driving, color vision, and peripheral vision. The scores on the subscales were added together for a total score, which ranged from 0 to 100. A higher score indicated improvement in quality of life due to vision function
Measured: Baseline, month 6
Changes in the Quality of Life According to the Short Form (36) Health Survey (SF-36)Questionnaires
SF-36 summary measures are norm-based scores with mean = 50 and SD = 10. Higher scores indicate better health
Measured: Baseline, month 6
Changes in the Quality of Life According to Euro Quality of Life (EQ-5D) Questionnaires
The EQ-5D visual analog scale ranges from 0 to 100, 0 representing the worst and 100 the best imaginable health state.
Measured: Baseline, month 6
Increase Rate of the Internal Ocular Pressure (IOP ) : Patients With ≥10% Increase in IOP Compared to Baseline
The proportion of patients with ≥ 10% increase in Internal Ocular Pressure (IOP) compared to baseline at any post-baseline visit.
Measured: Baseline, month 6

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ranibizumab in people with Visual Impairment and Macular Edema, run by Novartis Pharmaceuticals at 64 sites in 4 countries.

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 3 inclusion and 8 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 27 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 64 sites in Germany, United Kingdom, Hungary, Poland. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?

Mean Average BCVA Change From Month 1 Through Month 6 to Baseline (time frame: Baseline, month 6). 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 NCT01396083.

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 27 Sep 2016; AzTrials last refreshed its copy on 8 Nov 2026.
