About this study
Official title: A Phase 3 Multicenter, Randomized, Double-Masked, Placebo-Controlled Study of the Safety and Efficacy of Difluprednate in the Treatment of Inflammation Following Ocular Surgery
The purpose of this phase III study is to determine the efficacy of difluprednate in the treatment of inflammation following ocular surgery.
- Conditions
- Inflammation
- Being tested
- Difluprednate, Placebo
- Medical subject headings
- Inflammation
What participants receive

DifluprednateDrug
PlaceboDrug
| Study group | Role | What they receive |
|---|---|---|
| Difluprednate 0.05% BID | Experimental | Difluprednate 0.05% 1 drop BID for 14 days Receives: Drug: Difluprednate |
| Difluprednate 0.05% QID | Experimental | Difluprednate 0.05% 1 drop QID for 14 days Receives: Drug: Difluprednate |
| Placebo | Placebo comparator | Placebo for 14 days. Placebo was administered BID for 14 days and QID for 14 days. The outcomes of the 2 placebo groups were examined and were determined to be statistically indistinguishable so the placebo groups were pooled for comparison with the difluprednate groups. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Anterior Chamber Cell Grade of "0" on Day 8 (Difluprednate QID vs Placebo).
Measured on a 0 to 4 scale: "0" is ≤ 1 cell; "1" is 2-10 cells; "2" is 11-20 cells; "3" is 21-50 cells; "4" is > 50 cells.
Measured: Day 8 (QID)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Difluprednate in people with Inflammation, run by Sirion Therapeutics, Inc. 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 25 inclusion and 0 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 2 Jul 2009. 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. 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 2 Jul 2009). 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?
Anterior Chamber Cell Grade of "0" on Day 8 (Difluprednate QID vs Placebo). (time frame: Day 8 (QID)). 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 NCT00430092, 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 2 Jul 2009.
