Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Must have a diagnosis of acute bacterial conjunctivitis and exhibit purulent conjunctival discharge and redness in at least one eye.
  • Females of must utilized reliable methods and have a negative pregnancy test.

Exclusion criteria

Exclusion Criteria:

  • Pregnant or nursing females.
  • Known to fluoroquinolones or to any of the study ingredients.
  • Use of any antibiotic within 72 hours of treatment.
  • Any disease or condition that could interfere with the safety and efficacy evaluations of the study medications.
  • Participation in an ophthalmic drug or device research study within 30 days prior to entry into the study.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Clinical Resolution of Baseline Bacterial Conjunctivitis

    The absence (grade 0 on the ordinal scale) of ocular discharge and bulbar conjunctival injection

    Time frame: Day 5 +/- 1 day

  2. Microbial Eradication of Baseline Bacterial Infection

    Absence (grade 0 on the ordinal scale) of all ocular bacterial species that were present at or above the threshold value for that species from the Cagle list at baseline.

    Time frame: Day 5 +/- 1 day

Secondary outcomes

  1. Clinical Resolution of Baseline Bacterial Conjunctivitis

    The absence (grade 0 on the ordinal scale) of ocular discharge and bulbar conjunctival injection

    Time frame: Day 8 or 9

  2. Microbial Eradication of Baseline Bacterial Infection

    Absence (grade 0 on the ordinal scale) of all ocular bacterial species that were present at or above the threshold value for that species from the Cagle list at baseline.

    Time frame: Day 8 or 9

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jun 2006, a primary completion of Nov 2007 and a completion of Nov 2007. It does not say whether these dates are actual or estimated.

Results were first posted in Aug 2009, 1 year 9 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 24, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
