Efficacy Study to Evaluate Antimicrobial Effectiveness of ZuraPrep™ (ZX-ZP-0055)

A Pilot Clinical Evaluation of the Antimicrobial Effectiveness of Topically Applied ZuraPrep™

This is a randomized, paired-comparisons design where each subject receives two of the planned treatments.

ZuraPrep is being evaluated for safety and efficacy as a preoperative skin preparation against the Tentative Final Monograph (TFM) 10-minute end point recently revised by the FDA for the lower bound of a 95% confidence interval whereas there must be specific reductions of normal flora in the abdomen and groin areas. A positive control will be evaluated as well.

For replacement subjects, have Screening Day baseline counts of at least 1.3 x 103 CFU/cm2 per abdominal site (left and right) and/or 1.0 x 105 CFU/cm2 per groin site (left and right).
