Inclusion criteria

  1. Diagnosis in one or both eyes of bacterial conjunctivitis based on:

    • symptoms less than or equal to 24 hours prior to first visit
    • rating > or equal to 1 for bulbar conjunctival injection
    • must have a rating > 1 for conjunctival discharge / exudate in at least one eye (the same eye as bulbar conjunctival injection ) at Visit 1, and
  2. Must experience some matting in the affected eye(s).
  3. 1 year of age or older, of any race and either sex
  4. Able to understand and sign an that has been approved by an Institutional Review Board; or if the subject is a minor, the informed consent must be signed and understood by the subjects legally authorized representative (parent or guardian). Assent to participate should be obtained from subjects 6 years of age or older unless not allowed by local regulation.
  5. Must agree to comply with study visit schedule, photographs and other study requirements. If subject is a minor, the parent or guardian must agree to ensure compliance.

Exclusion criteria

Exclusion Criteria:

  1. Cannot have had bacterial conjunctivitis as reported by subject (or parent if subject is a minor) for > 24 hours.
  2. Any current lid disease on clinical examination.
  3. Known or suspected allergy or to fluoroquinolones.
  4. Suspected fungal, viral (e.g. Herpes simplex) or Acanthamoeba infection, based on clinical observation.
  5. Any systemic or ocular disease or disorder, complicating factors or structural abnormality that would negatively affect the conduct or outcome of the study (e.g., hepatitis, acute or chronic renal insufficiency).
  6. Use of topical ocular medications during the study period.
  7. Antibiotics (systemic or topical) may not be used within 7 day of visit 1 or anytime after this visit for the duration of the study.
  8. Women of not using reliable means of .
  9. Women who are pregnant or lactating.
  10. Enrollment of more than one person per household at the same time.
  11. Enrollment of the investigator or his or her staff, family members of the investigator, family members of the investigator's staff, or individuals living in the households of these individuals.
  12. Participation in any drug or device study within 30 days of entering this study.
Terms in these criteria, in plain language(5)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Exploratory Outcomes From Digital Photography

    Photographs were taken before and after treatment. Outcome is the number of patients whose photographs showed a subjective visual change based upon an exploratory review of patient photographs in signs of bacterial conjunctivitis before and after treatment.

    Time frame: 24 hours after administration of first dose

Secondary outcomes

  1. Exploratory Evaluation of Changes in Ocular Signs and Symptoms

    Number of patients who had clinical resolution (0 on all scales below) from baseline (Day 1) to Day 2 in ocular and symptoms of bacterial conjunctivitis: Bulbar Conjunctival Injection - 0 (none) to 4 (Severe) scale. Conjunctival Discharge (Mucopurulent) - 0 (none) to 3 (Severe) scale. Lid Erythema - 0 (none) to 3 (Severe) scale. Lid Swelling - 0 (none) to 3 (Severe) scale. Palpebral Conjunctiva - 0 (none) to 3 (Severe) scale. Foreign Body Sensation - 0 (none) to 3 (Severe) scale. Tearing - 0 (none) to 3 (Severe) scale. Photophobia - 0 (none) to 3 (Severe) scale.

    Time frame: Baseline (Day 1) to Day 2

  2. Microbiological Culture Evaluation/Eradication Percent - Enterobacter Faecalis and Candida Albicans

    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

    Time frame: 24 hours after administration of first dose

  3. Microbiological Culture Evaluation/Eradication Percent - Eradication of All Other Isolates and Corynform-like

    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

    Time frame: 24 hour after administration of first dose

  4. Microbiological Culture Evaluation/Eradication Percent - Staphylococcus Aureus, Steptococcus Pneumoniae, and Enterobacter Cloacae

    Eradication percent (absence of specified bacteria) of each bacteria identified at Day 1

    Time frame: 24 hours after administration of first dose
