What is being measured

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

  1. Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) Score at 6 Months

    BCVA score in the study eye was based on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity charts (number of correct letters) and assessed at a starting distance of 4 meters.

    Measured: Baseline and 6 months

Secondary outcomes (6)

  1. Percentage of Participants Who Gained ≥ 15 Letters in BCVA Score at Month 6 Compared With Baseline

    BCVA score based on the ETDRS visual acuity charts (number of correct letters) and assessed at a starting distance of 4 meters.

    Measured: Baseline and 6 months

  2. Percentage of Participants Who Lost < 15 Letters in BCVA Score at Month 6 Compared With Baseline

    BCVA score based on the ETDRS visual acuity charts (number of correct letters) and assessed at a starting distance of 4 meters.

    Measured: Baseline and 6 months

  3. Percentage of Participants With a Central Foveal Thickness of ≤ 250 μm at Month 6

    A central reading center assessed all optical coherence tomography (OCT) images. Central foveal thickness was defined as the center point thickness.

    Measured: 6 months

  4. Mean Absolute Change From Baseline in Central Foveal Thickness at Month 6

    A central reading center assessed all OCT images. Central foveal thickness was defined as the center point thickness.

    Measured: Baseline and 6 months

  5. Mean Change From Baseline in the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) Near Activities Subscale Score at Month 6

    The NEI VFQ-25 (v. 2000; Interviewer Format) consisted of the base set of 25 questions, plus the optional additional questions (where questions A3, A4, and A5 pertained to the Near Activities Subscale). Scores ranged from 0 to 100; a higher score represented better functioning.

    Measured: Baseline and 6 months

  6. Mean Change From Baseline in the NEI VFQ-25 Distance Activities Subscale Score at Month 6

    The NEI VFQ-25 (v. 2000; Interviewer Format) consisted of the base set of 25 questions, plus the optional additional questions (where questions A6, A7, and A8 pertained to the Distance Activities Subscale). Scores ranged from 0 to 100; a higher score represented better functioning.

    Measured: Baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ranibizumab injection 0.3 mg and Ranibizumab injection 0.5 mg in people with Macular Edema and Retinal Vein Occlusion, run by Genentech, Inc..

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 9 inclusion and 35 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 28 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Feb 2011). 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?

Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) Score at 6 Months (time frame: Baseline and 6 months). 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 NCT00485836, which also lists 2 linked publications.

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 28 Jul 2017; AzTrials last refreshed its copy on 8 Nov 2026.
