Brief Summary:

A randomized, double blind, phase II multicenter trial with the objective of assess the safety and efficacy of the PRO-157 ophthalmic solution in three different dosing regimens, versus Moxifloxacin, versus Gatifloxacin in patients with bacterial conjunctivitis.

Number of participants: 300 eyes, 60 per group.

Criteria for evaluation:

Measurements of effectiveness: Main efficacy criterion It will be determined as effective if there is a reduction in number or species of bacterial flora by comparing the basal culture against the final culture among the five different patient groups.

Reduction or absence of infection with the clinical evaluation through signs and symptoms.

Safety Measurements: it will be determined by visual acuity and adverse events Patients recruited will be treated for 7, for protocol purpose, the infected eye (s) will be taken into account at the time of baseline, however the study medication and procedures will be applied and performed in both eyes to protect the healthy eye.

The study is divided into the following evaluation periods:

Visit 1 baseline (day 1), visit 2 (day 3), final visit (day 8) and a telephone call (day 23) for the evaluation of adverse events.

Subjects will be allocated to any of the following regimen dosages:

  • PRO-157 1 drop 2 times daily
  • PRO-157 1 drop 3 times daily
  • PRO-157 1 drop 4 times daily
  • Moxifloxacin 1 drop 3 times daily
  • Gatifloxacin 1 drop 3 times daily. All regimen dosage will have a duration of 7 days. An artificial tear preservative free (Lagricel Ofteno®) will also be applied 15 minutes before instillation of study drug, during study period.

Data Analysis: The data will be analyzed by Intention to Treat (ITT) and per Protocol (PP) in which each of the variables is described, the ITT population will be constituted by all subjects recruited who have received at least one dose of the study, the PP population will be the subset of ITT composed of all subjects without any major deviation from the protocol and the bivariate analysis will be performed in this group.

Continuous quantitative variables are expressed and presented by measures of central tendency and dispersion (mean, standard deviation and ranges). Qualitative nominal and ordinal variables are presented by means of frequencies and proportions. The level of significance was an alpha of 0.05 or less.

Primary Outcome Measures :
  1. Change From Baseline Bacterial Culture [ Time Frame: up to one week ]

    Efficacy will be determined comparing the cultures of the lower conjunctival pouch, of the baseline (day 1) against final visit (day 8), quantifying and identifying the colony forming units (CFU) by genus and species.

    The evaluated variable is discrete quantitative type and the scale of measurement used will be CFU x mL considering the eradication, reduction or proliferation of the bacterial agent. It will be determined as effective if there is a reduction in number of bacterial flora in at least 95% of the evaluated subjects.


  2. Adverse Events [ Time Frame: during the intervention period for 7 days, and 15 days after the final visit ]
    Number of adverse events: dependent variable, discrete quantitative, the number of adverse events per group will be compared at the end of the study and it will be considered safe if there is not greater increase of 5% of serious adverse events.


Secondary Outcome Measures :
  1. Cases Frequency of Ocular Secretion [ Time Frame: Up to one week. ]
    Secretion ocular: qualitative ordinal variable. The secretion was evaluated by subject of study as present / absent, taking into consideration that each study subject represents two probable cases, one for each eye. On this premise, the statistical analysis of the number of cases reported in the final visit was made by study group.

  2. Number of Cases of Conjunctival Hyperemia [ Time Frame: up to one week ]
    Conjunctival hyperemia: qualitative ordinal variable. The conjunctival hyperemia was evaluated by subject of study as present / absent, taking into consideration that each study subject represents two probable cases, one for each eye. On this premise, the statistical analysis of the number of cases reported in the final visit was made by study group.

  3. Chemosis Frequency [ Time Frame: up to one week ]
    Chemosis: qualitative ordinal variable, measurement scale absent or present. The chemosis was evaluated by subject of study as present / absent, taking into consideration that each study subject represents two probable cases, one for each eye. On this premise, the statistical analysis of the number of cases reported in the final visit was made by study group.

  4. Eyelid Edema Frequency [ Time Frame: Up to one week ]

    Eyelid edema: qualitative ordinal variable, measurement scale absent or present.Between baseline (day 0) versus final visit (day 7).

    The eyelid edema was evaluated by subject of study as present / absent, taking into consideration that each study subject represents two probable cases, one for each eye. On this premise, the statistical analysis of the number of cases reported in the final visit was made by study group.


  5. Frequency of Corneal Epithelial Defects [ Time Frame: Up to one week ]

    Corneal epithelial defects: qualitative ordinal variable, measurement scale present or absent.

    The corneal epithelial defects was evaluated by subject of study as present / absent, taking into consideration that each study subject represents two probable cases, one for each eye. On this premise, the statistical analysis of the number of cases reported in the final visit was made by study group.
