Trial Outcomes & Findings for Clinical Study to Compare 3 Multi-Layered Foam Dressings for the Management of Chronic Wounds (NCT NCT03662997)

NCT ID: NCT03662997

Last Updated: 2021-04-01

Results Overview

Dressing strike-through determined @ Wk1 Day 3\&7, and Wk3 Day 17\&21. Dressing strike-through that occurred Day 3 and/or 7, Day 17 and/or 21 were included in final dataset. Contributing factors to strike-through: Saturation of dressing pad: * Inappropriate dressing type * Inappropriate dressing change freq. (i.e. more frequent changes required) * Change in wound condition (e.g. increase in exudate amt) Dislodgement of dressing: * Suboptimal dressing application (e.g. selection of inappropriate dressing size, failure to clean periwound skin before applying dressing, insufficient fixation) * Exposure of dressing to mechanical forces (e.g. off-loading devices, patient mobility) * Patient interference w/ dressing Dressing design deficiency: * Insufficient fluid handling capacity (absorption, retention and/or moisture vapor transmission) * Insufficient adhesion * Insufficient conformability (i.e. ability to conform to body contours \& challenging anatomical wound locations)

PRIMARY outcome

Timeframe: 4 weeks

Population: Intent-to-treat (ITT) analysis set of superiority. Participants were combined into 2 cohorts: participants in the Five-layer vs Hydropolymer into one cohort, \& Five-layer vs Hydrocellular were similarly combined into a second cohort to allow for reporting and analysis in order to compare # of incidences of strike-through when participants received one dressing or the other first for the 4 week treatment phase. Number of participants analyzed differ from baseline due to missing values.

Dressing strike-through determined @ Wk1 Day 3\&7, and Wk3 Day 17\&21. Dressing strike-through that occurred Day 3 and/or 7, Day 17 and/or 21 were included in final dataset. Contributing factors to strike-through: Saturation of dressing pad: * Inappropriate dressing type * Inappropriate dressing change freq. (i.e. more frequent changes required) * Change in wound condition (e.g. increase in exudate amt) Dislodgement of dressing: * Suboptimal dressing application (e.g. selection of inappropriate dressing size, failure to clean periwound skin before applying dressing, insufficient fixation) * Exposure of dressing to mechanical forces (e.g. off-loading devices, patient mobility) * Patient interference w/ dressing Dressing design deficiency: * Insufficient fluid handling capacity (absorption, retention and/or moisture vapor transmission) * Insufficient adhesion * Insufficient conformability (i.e. ability to conform to body contours \& challenging anatomical wound locations)

SECONDARY outcome

Timeframe: 4 weeks

Population: ITT analysis set. Means and standard deviations represent participants' responses from follow-up visits aggregated. Participants were combined into 2 cohorts: participants in the Five-layer vs Hydropolymer into one cohort, \& Five-layer vs Hydrocellular were similarly combined into a second cohort to allow for reporting \& analysis in order to compare health-related quality-of-life when using each type of dressing. Number of participants analyzed differ from baseline due to missing values.

The SF-12 health survey consists of 12 questions that yield an eight-scale profile of functional health and well-being, and 2 component summary measures of physical and mental health. SF-12 scores range from 0 to 100 with lower scores indicate lower levels of health. SF-12 questionnaire was administered at Screening/Baseline, Day 14, and Day 28 visits, and scored by a 3rd party vendor. Results are mean differences between five-layer vs the comparator dressing and presented for each of the 8 health domains, and 2 component summary measures. Negative scores indicate lower SF-12 scores (indicating lower levels of health) for the five-layer treatment group; positive scores indicate higher SF-12 scores for the five-layer group.

POST_HOC outcome

Timeframe: 1 week

Population: Intent-to-treat (ITT) analysis set of superiority. Participants were combined into 2 cohorts: participants in the Five-layer vs Hydropolymer into one cohort, \& Five-layer vs Hydrocellular were similarly combined into a second cohort to allow for reporting and analysis in order to compare the % of participant in compliance with 7-day wear time protocol in the first week of treatment. Number of participants analyzed differ from baseline due to missing values.

Compliance with the 7-day wear time protocol, within the first critical week of treatment. Compliance is defined as participants who wore a dressing continuously from time of application until removal at Day 7 visit. This includes participants whose dressing did not have strikethrough up to Day 7 and those who wore their dressing until strikethrough at Day 7 when dressing was removed.
