What is being measured

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

  1. Change in Levels of Biomarkers After Dosing With Maxidex

    Biomarkers are an indicatior of inflammation. In this study, the level of biomarkers before and after anti-inflammatory treatment (Maxidex) is measured for the treatment group. In the control group, the biomarker level is measured at baseline and 2 weeks later. ddCt (Delta-Delta-Ct) is the number of polymerase chain reaction (PCR) cycles required to generate a quantifiable number.

    Measured: Baseline to 2 weeks

Secondary outcomes (4)
  1. Correlation Between Biomarker Expression and Ocular Symptoms

    Correlation factor: tumor necrosis factor (TNF) messenger RNA (mRNA) vs. OSDI (Ocular Surface Disease Index).

    Measured: Baseline to 2 weeks

  2. Correlation Between Biomarker Expression and Tear Film Break up Time

    Correlation factor:

    TNFmRNA vs. TFBUT (Tear Film Break-up Time)

    Measured: Baseline to 2 weeks

  3. Correlation Between Biomarker Expression and NaFl (Sodium Fluorescein) Staining

    Correlation factor:

    TNFmRNA vs. NaFl staining

    Measured: Baseline to 2 weeks

  4. Correlation Between Biomarker Expression and the Schirmer Test

    Correlation factor: TNFmRNA vs. Schirmer

    Measured: Baseline to 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Maxidex and No treatment in people with Sjogren's Syndrome, run by Alcon Research at 2 sites in Canada.

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 3 inclusion and 7 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 12 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 12 Apr 2010). 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 Levels of Biomarkers After Dosing With Maxidex (time frame: Baseline to 2 weeks). 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 12 Apr 2010.
