About this study

Official title: Evaluation of Topical Vigamox in the Initial Management of Ocular Graft-Versus-Host Disease

In this study the investigators seek to prospectively measure the response of ocular graft-versus-host disease (GVHD) patients to treatment with topical Vigamox. The investigators will accomplish this by enrolling patients with bilateral ocular GVHD and treating one eye with topical Vigamox and the other eye with a placebo eye drop. By assessing the response to treatment with Vigamox, the investigators hope to identify a role for topical antibiotic treatment in ocular GVHD.

What is being measured

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

  1. Change in Ocular comfort

    • Ocular comfort will be rated by the participant for each eye on a 0-10 Visual Analog Scale
    • 0=no discomfort and 10=worst discomfort

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

Secondary outcomes (5)
  1. Change in Ocular Surface Disease Index (OSDI) score

    • 12 questions with answers ranging from 0=none of the time to 4=all of the time
    • The OSDI©is assessed on a scale of 0 to 100, with higher scores representing greater disability. The index demonstrates sensitivity and specificity in distinguishing between normal subjects and patients with dry eye disease.

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

  2. Change in Visual acuity

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

  3. Change in the Degree of Conjunctival injection

    -The degree of conjunctival injection will be graded based on the Validated Bulbar Redness scale

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

  4. Change in Corneal/conjunctival punctate epithelial erosions

    • The clinical exam will be conducted using the National Eye Institute Fluorescein Staining Scale to grade the degree of corneal and conjunctival stain with a cobalt blue slit lamp filter
    • This test divides the cornea into 5 sections. Staining is graded on a scale of 0-3, with 0 indicating absence of staining and 3 indicating severe staining.

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

  5. Change in Culture results

    -Conjunctival bacterial cultures will be obtained via swab before and after treatment

    Measured: First clinic visit through second clinic visit (estimated to be 9-14 days)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Vigamox in people with Ocular Graft-versus-host Disease, run by Washington University School of Medicine.

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 1 inclusion and 5 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: withdrawn, as of the sponsor's last update on 8 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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 Ocular comfort (time frame: First clinic visit through second clinic visit (estimated to be 9-14 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 8 Aug 2023.
