What is being measured

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

  1. Change in Fluorescein Corneal Staining (FCS) Score From Baseline to Last Observation Carried Forward (LOCF)

    FCS indicates the damage to the corneal epithelium. Per the National Eye Institute/Industry Workshop report, the cornea was divided into 5 fractions, each of which was given a staining score from 0 to 3, and the total score was calculated(0-15). 0 is better.The change from baseline (CFB) to LOCF at the end of instillation (LOCF endpoint) was used to analyze dose-response. A general linear model was used to examine if slope parameters were not equal to zero.

    Measured: Baseline, 4weeks

Secondary outcomes (1)
  1. Change in Lissamine Green Conjunctival Staining (LGCS) Score From Baseline to Last Observation Carried Forward (LOCF)

    LGCS indicates the damage to the conjunctival epithelium. Per the National Eye Institute/Industry Workshop report, the conjunctival sac and the conjunctina was divided into 6 ractions, each of which was given a staining score from 0 to 3, and the total score was calculated(0-18). 0 is better. The CFB to each study time point was compared between the active-drug groups and the placebo group, and LOCF endpoint scores were used to compare the active-drug groups and the placebo group. In each treatment group, baseline scores and those obtained at each study time point were compared.

    Measured: Baseline, 4weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 1% OPC-12759 ophthalmic suspension and 2% OPC-12759 ophthalmic suspension in people with Dry Eye Syndromes, run by Otsuka Pharmaceutical Co., Ltd. at 6 sites in Japan.

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 6 inclusion and 9 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 13 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 6 sites in Japan. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 5 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?

Change in Fluorescein Corneal Staining (FCS) Score From Baseline to Last Observation Carried Forward (LOCF) (time frame: Baseline, 4weeks). 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 NCT00475319, 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 13 Jun 2013.
