Study summary

The objective of the study is to demonstrate the antimicrobial efficacy of the Zurex Preoperative Prep (ZuraPrep - clear) on skin flora of the abdomen and inguinal regions of human subjects.

Read the detailed description

The primary objective of this study is to measure the antimicrobial effectiveness of a single investigational test article, ZuraPrep™ as specified by the Healthcare Antiseptics, Topical Antimicrobial Drug Products Final Rule of December 20, 2017. The treatments will be ZuraPrep™ as the investigational test article, ChloraPrep® as an active control, and ZuraPrep™ Vehicle as a negative control. For efficacy at 30 seconds post-prep, the test article should be superior to the negative control using a margin of 1.2 log10 CFU/cm2 and non-inferior to the active control using a margin of 0.5 log10 CFU/cm2.

What researchers measure

Primary outcomes

  1. Bacterial Reduction - Groin

    A 3-log10 CFU/cm\^2 bacterial reduction on the inguinal region is considered a success.

    Time frame: 30 seconds post product application

  2. Bacterial Reduction - Abdomen

    A 2-log10 CFU/cm\^2 bacterial reduction on the abdomen region is considered a success.

    Time frame: 30 seconds post product application

Secondary outcomes

  1. Bacterial Counts Not Exceeding Baseline in the Abdomen and Groin Region

    Bacterial counts should not exceed baseline on the abdomen or groin region

    Time frame: 6 hours post product applcation
