In-vivo Efficacy Study of Patient Preoperative Preps

September 30, 2024 updated by: Solventum US LLC

Assessment of the Antimicrobial Efficacy of 3M CHG/IPA Preoperative Skin Preparation Against Resident Human Skin Flora on the Abdominal and Inguinal Regions

The purpose of this study is to evaluate the antimicrobial efficacy of the 3M CHG/IPA Prep on skin flora of the abdominal and inguinal regions of human subjects.

Study Overview

Detailed Description

The primary efficacy is evaluated by demonstration that the product provides a lower bound of the 95% confidence interval of percent responders that is greater than or equal to 70%. On the abdominal sites, a responder is defined as a subject with a 2-log10 per cm2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at 6 hours. On the inguinal sites, a responder is defined as a subject with a 3-log10 per cm2 bacterial reduction at 10 minutes and for whom the skin flora does not return to baseline at 6 hours.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Safety as Assessed by Skin Irritation Scores
Time Frame: Baseline
Skin irritation rating (0-3) scores for dryness, edema, erythema and rash. 0 = no reaction, 1 = mild, 2 = moderate, 3 = severe. A skin irritation rating of 3 in any category represents significant irritation and qualifies as an adverse event.
