About this study
Official title: A Phase IIIB, Multicenter, Randomized, Double-Masked, Parallel-Group, Active-Controlled Study of the Safety and Efficacy of Difluprednate Ophthalmic Emulsion, 0.05% (Durezol™) 4 Times Daily (QID) and Prednisolone Acetate Ophthalmic Suspension, 1.0% (Pred Forte™) QID for the Treatment of Inflammation Following Cataract Surgery in Children 0 to 3 Years of Age
The primary objective of this study was to compare the safety and efficacy of Durezol™ compared to Pred Forte™ for the treatment of inflammation following cataract surgery in a pediatric population 0 to 3 years of age.
Read the detailed description
Parents or guardians instilled patients' assigned study medications once on the day of surgery (Day 0) and 4 times daily (QID) beginning on the day after surgery (Day 1) for 14 days followed by a tapering period of 14 days (dependent upon the Investigator's determination of adequate response to treatment). Patients were evaluated for safety and efficacy on the following visits: Day 0 (day of surgery), Day 1, Day 8 ± 1 day, Day 15 ± 2 days and Day 29 ± 2 days (end of study drug treatment). Additional safety visits occurred at 1 week after the last dose + 2 days and at 3 Months + 1 week. No inferential statistical analysis was planned for this study. Data was summarized using descriptive statistics.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Patients With an Anterior Cell Grade of 0 (no Cells) at Day 15 ± 2 Days
Anterior cell grade was assessed by the Investigator during slit lamp or ophthalmoscopy/light examination and graded on a 5-point scale: Grade 0=0 cells; Grade 1=1 to 10 cells; Grade 2=11 to 20 cells; Grade 3=21 to 50 cells; Grade 4=>50 cells. The presence of blood cells (red and white) in the anterior chamber of the eye (the fluid-filled space inside the eye between the iris and the cornea's innermost surface) is a sign of intraocular inflammation. A score of 0 indicates an absence of inflammation.
Measured: Day 15 ± 2 days

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of this study was to compare the safety and efficacy of Durezol™ compared to Pred Forte™ for the treatment of inflammation following cataract surgery in a pediatric population 0 to 3 years of age.
Detailed description
Parents or guardians instilled patients' assigned study medications once on the day of surgery (Day 0) and 4 times daily (QID) beginning on the day after surgery (Day 1) for 14 days followed by a tapering period of 14 days (dependent upon the Investigator's determination of adequate response to treatment). Patients were evaluated for safety and efficacy on the following visits: Day 0 (day of surgery), Day 1, Day 8 ± 1 day, Day 15 ± 2 days and Day 29 ± 2 days (end of study drug treatment). Additional safety visits occurred at 1 week after the last dose + 2 days and at 3 Months + 1 week. No inferential statistical analysis was planned for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Difluprednate ophthalmic emulsion, 0.05% and Prednisolone acetate ophthalmic suspension, 1.0% in people with Cataracts and Inflammation, 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 4 inclusion and 12 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 Jun 2013. 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 19 Jun 2013). 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?
Percentage of Patients With an Anterior Cell Grade of 0 (no Cells) at Day 15 ± 2 Days (time frame: Day 15 ± 2 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 Jun 2013.
