Trial summary

The purpose of this study is to assess the association of retinal detachment (separation of the retina [the innermost layer of the eyeball] from its connection at the back of the eye) with exposure to oral ciprofloxacin or oral fluoroquinolones. Read more about this study

  • Child, Adult, Older adult

Study population: Participants with exposure to oral fluoroquinolones

Who may be able to join

  • At least 1 year of enrollment in the study for medical and pharmacy benefits after their cohort (group) entry (the day of their first ophthalmologist visit) for case-control design
  • Oral fluoroquinolone like levofloxacin or ciprofloxacin must be dispensed to participants for cohort design
  • At least one visit to an ophthalmologist and enrolled at least for 1 year in the study for medical and pharmacy benefits prior to the date of first occurrence of the exposure of levofloxacin or ciprofloxacin for cohort design
  • At least one visit to an ophthalmologist and enrolled at least for 1 year in the study for medical and pharmacy benefits prior to the diagnosis of their first retinal detachment (separation of the retina [the innermost layer of the eyeball] from its connection at the back of the eye) for case-only design

Who cannot join

  • Prior diagnosis of retinal detachment , prior diagnosis or procedure for inflammatory conditions of the eyeball, or hospital admission between cohort entry and the date of the retinal detachment

About this study

Official title: Oral Fluoroquinolones and the Risk of Retinal Detachment

The purpose of this study is to assess the association of retinal detachment (separation of the retina [the innermost layer of the eyeball] from its connection at the back of the eye) with exposure to oral ciprofloxacin or oral fluoroquinolones.

Read the detailed description

This is an observational (in which the investigators observe the outcomes of the study participants but do not intervene by, e.g, assigning the treatments) and retrospective (a study in which the exposures and outcomes occurred before the study began) study. It will use data from the Optuminsight and Truven Commercial Claims and Encounters databases, each of which will be evaluated separately using 3 designs: (1) Case-control (a design that compares the cases [study participants], ie, those with retinal detachment to controls, ie, a sample of similar people who did not have a retinal detachment) to assess whether their exposures to fluoroquinolones (FQs) differed. Two case-control studies are planned, one (replication) that mimics a previously reported study, the other (revised) that addresses more potential confounders than did that study , (2) Cohort (a design that follows the participants exposed to FQs and those not exposed to FQs to assess whether the two groups had different risks of developing retinal detachment), (3) Case-only (a design where the exposure history of individuals who had retinal detachment are examined to assess whether they were more likely to have had it when they were exposed to FQs than when they were not).

Study groupRoleWhat they receive
Participants exposed to oral fluoroquinolonesOral fluoroquinolones in this study are ciprofloxacin, levofloxacin, gatifloxacin, gemifloxacin, moxifloxacin, norfloxacin, and ofloxacin.

What is being measured

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

  1. Number of Retinal Detachments With Exposure to Oral Ciprofloxacin or to Oral Fluoroquinolones

    Oral fluoroquinolones in this study are gatifloxacin, gemifloxacin, levofloxacin, moxifloxacin, norfloxacin, and ofloxacin.

    Measured: 11 years

Secondary outcomes (6)
  1. Number of Retinal Detachments With Exposure to Oral Ciprofloxacin or to Oral Fluoroquinolones (Revised Case-Control Design)

    Oral fluoroquinolones in this study are gatifloxacin, gemifloxacin, levofloxacin, moxifloxacin, norfloxacin, and ofloxacin. Revised Case-control design is used for assessment of this outcome measure.

    Measured: 11 years

  2. Number of Retinal Detachments With Exposure to Individual Oral Fluoroquinolones (Revised Case-Control Design)

    Oral fluoroquinolones in this study are gatifloxacin, gemifloxacin, levofloxacin, moxifloxacin, norfloxacin, and ofloxacin. Revised Case-control design is used for assessment of this outcome measure.

    Measured: 11 years

  3. Number of Retinal Detachments With Exposure to Oral Fluoroquinolones Along With Oral Beta-Lactam antibiotic (Case-Control Design)

    Oral fluoroquinolones in this study are gatifloxacin, gemifloxacin, levofloxacin, moxifloxacin, norfloxacin, and ofloxacin. Case-control design is used for assessment of this outcome measure.

    Measured: 11 years

  4. Number of Retinal Detachments With Exposure to Oral Levofloxacin and Ciprofloxacin (Cohort Design)

    Cohort design is used for assessment of this outcome measure.

    Measured: 11 years

  5. Number of Retinal Detachments During the Period of Exposure With Oral Levofloxacin and Ciprofloxacin (Case-Only Design)

    Case-only design is used for assessment of this outcome measure.

    Measured: 11 years

  6. Number of Retinal Detachments During the Period of non-Exposure to Oral Levofloxacin and Ciprofloxacin (Case-Only Design)

    Case-only design is used for assessment of this outcome measure.

    Measured: 11 years

Questions about this trial

What is this clinical trial studying?

An observational study of Retinal Detachment, run by Janssen Research & Development, LLC.

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 1 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.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of Retinal Detachments With Exposure to Oral Ciprofloxacin or to Oral Fluoroquinolones (time frame: 11 years). 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.
