Inclusion criteria

  • Clinically diagnosed with bacterial conjunctivitis

Exclusion criteria

  • Signs and/or symptoms of conjunctivitis for more than 96 hours
  • Signs and/or symptoms suggestive of fungal, viral, or allergic conjunctivitis
  • Clinical diagnosis of chlamydia in either eye

Treatment and study plan

Gatifloxacin 0.5% eye drops

Drug

Day 1 = 1 drop of study medication every 2hrs up to 8 times total; day 2-5 = 1 drop twice daily

Placebo Eye Drops

Drug

Day 1 = 1 drop of study medication every 2hrs up to 8 times total; day 2-5 = 1 drop twice daily

Primary outcomes

  1. Percentage of Patients With Clearing (Clinical Success) of Conjunctival Hyperemia and Conjunctival Discharge at Day 6

    Time frame: Day 6

    Percentage of patients that achieved clinical success, defined as achievement of a score of zero for both conjunctival hyperemia and conjunctival discharge in the study eye at Day 6. Conjunctival hyperemia and conjunctival discharge were each assessed on a 4-point severity grade scale (0=none, +1=mild, +2=moderate, +3=severe).

Secondary outcomes

  1. Percentage of Patients With Microbiological Cure at Day 6

    Time frame: Day 6

    Percentage of patients with microbiological cure, defined such that all bacteria present in the study eye at Day 1 (Baseline) are eradicated (or absent) at Day 6 based on a Classification of Microbial Response. (Eradication=pathogen is absent in follow-up culture; Reduction=pathogen is reduced from baseline below threshold count in follow-up culture; Persistence=pathogen reduced from baseline but is above or equal to threshold count in follow-up culture; and Proliferation=pathogen has increased in count from baseline in follow-up culture)

  2. Percentage of Patients With Clinical Improvement of Ocular Signs at Day 6

    Time frame: Day 6

    Percentage of patients with clinical improvement of ocular signs at Day 6 based on a 4-point scale (0 = none, 1 = mild, 2 = moderate, and 3 = severe), defined as a decrease (improvement) from Day 1 (Baseline) in the total score of conjunctival hyperemia and mucopurulent discharge (pus),with no increase (worsening) from Day 1 (Baseline) in either individual variable in the study eye.

  3. Percentage of Patients With Clinical Improvement of Ocular Symptoms at Day 6

    Time frame: Day 6

    Percentage of patients with clinical improvement of ocular symptoms at Day 6, defined as a decrease (improvement) from Day 1 (Baseline) in the total score of itching and tearing (each on 4-point scale: 0 = none, 1 = mild, 2 = moderate, and 3 = severe), with no increase (worsening) from Day 1 (Baseline) in any individual score in the study eye diagnosed with bacterial conjunctivitis
