What is being measured

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

  1. Change From Baseline (Day 0) in Anterior Chamber Cell Grade at Day 14

    Inflammatory cells in the anterior chamber were assessed by the investigator during slit lamp examination and graded on a 5-point scale, with 0 = ≤ 1 cell count; 1 = 2 to 10 cell count; 2 = 11 to 20 cell count; 3 = 21 to 50 cell count; and 4 = > 50 cell count.

    Measured: Baseline (Day 0), Day 14

Secondary outcomes (9)
  1. Change From Baseline (Day 0) in Anterior Chamber Cell Grade at All Time Points Other Than Day 14

    Inflammatory cells in the anterior chamber were assessed by the investigator during slit lamp examination and graded on a 5-point scale, with 0 = ≤ 1 cell count; 1 = 2 to 10 cell count; 2 = 11 to 20 cell count; 3 = 21 to 50 cell count; and 4 = > 50 cell count.

    Measured: Baseline (Day 0), Day 3, Day 7, Day 21, Day 28, Day 35, Day 42

  2. Change From Baseline (Day 0) in Anterior Chamber Flare Grade at All Time Points

    Anterior chamber flare (protein escaping from dialated vessels) was assessed by the investigator during slit lamp examination and graded on a 5-point scale, with 0 = none; 1 = mild (trace to clearly noticeable, visible); 2 = moderate; 3 = marked; and 4 = severe.

    Measured: Baseline (Day 0), Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  3. Proportion of Subjects With Anterior Chamber Cell Grade of 0

    Inflammatory cells in the anterior chamber were assessed by the investigator during slit lamp examination and graded on a 5-point scale, with 0 = ≤ 1 cell count; 1 = 2 to 10 cell count; 2 = 11 to 20 cell count; 3 = 21 to 50 cell count; and 4 = > 50 cell count. Proportion is reported as percentage of subjects.

    Measured: Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  4. Proportion of Subjects With Anterior Chamber Cell Count of 0

    Inflammatory cells in the anterior chamber were assessed by the investigator during slit lamp examination and recorded based on actual cell count. Proportion is reported as a percentage of subjects.

    Measured: Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  5. Proportion of Subjects With Anterior Chamber Cell Count ≤5 and Flare Grade of 0

    Inflammatory cells in the anterior chamber were assessed by the investigator during slit lamp examination and recorded based on actual cell count. Anterior chamber flare (protein escaping from dialated vessels) was assessed by the investigator during slit lamp examination and graded on a 5-point scale, with 0 = none; 1 = mild (trace to clearly noticeable, visible); 2 = moderate; 3 = marked; and 4 = severe. Proportion is reported as percentage of subjects.

    Measured: Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  6. Proportion of Subjects With Anterior Chamber Cell Grade ≤1

    As assessed by the investigator during slit lamp examination. Anterior chamber cell grade was graded on a 5-point scale, with 0 = no cells; 1 = 1 to 10 cells; 2 = 11 to 20 cells; 3 = 21 to 50 cells; and 4 = more than 50 cells. Proportion is reported as percentage of subjects.

    Measured: Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  7. Proportion of Subjects Who Discontinued Due to Lack of Efficacy

    Lack of efficacy was defined as those subjects who discontinued study participation either due to treatment failure or an adverse event with a preferred term of iridocyclitis, iritis, uveitis, or vitritis. Proportion is reported as percentage of subjects.

    Measured: Time to Event

  8. Change From Baseline (Day 0) in Visual Analog Scale (VAS) Total Symptom Score at All Time Points

    The following symptoms were each graded by the subject according to a 0-100 visual analog scale (VAS) using a mark on a 100 mm line (0 = absent, 100 = maximal): eye pain, photophobia, blurred vision, and lacrimation. The total symptom score was calculated as the sum of the 4 individual symptom scores.

    Measured: Baseline (Day 0), Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

  9. Change From Baseline (Day 0) in Slit-Lamp Total Sign Score at All Visits

    The following signs were each graded on a 0 - 3 scale (0 = absent; 1 = mild; 2 = moderate; 3 = severe): posterior synechia, hypopyon, limbal injection, and keratic precipitates. Peripheral synechia was graded by the combined number of clock hours affected (0 = absent; 1 = < 3 hrs; 2 = 3-6 hours; 3 = > 6 hours). The total sign score was calculated as the sum of the 5 individual sign scores, the anterior chamber cell grade and the anterior chamber flare grade. The minimum/best total sign score was 0, and the maximum/worst total sign score was 23.

    Measured: Baseline (Day 0), Day 3, Day 7, Day 14, Day 21, Day 28, Day 35, Day 42

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Difluprednate 0.05% ophthalmic emulsion and Prednisolone acetate 1.0% ophthalmic suspension in people with Endogenous Anterior Uveitis, run by Alcon Research at 1 site in United States.

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 5 inclusion and 10 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 15 Nov 2012. 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 United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Nov 2012). 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 (Day 0) in Anterior Chamber Cell Grade at Day 14 (time frame: Baseline (Day 0), Day 14). 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 NCT01201798, 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 15 Nov 2012.
