Trial Outcomes & Findings for Oral and Dermal Tolerability Clinical Study of an Experimental Denture Wipe (NCT NCT03478644)

NCT ID: NCT03478644

Last Updated: 2018-10-15

Results Overview

Proportion of participants experiencing or reporting TE oral AEs on or before 14 days of use treatments were reported. TE AEs include AEs that were identified during an oral soft tissue examination, a dermal assessment or reported by the subject. AEs were categorized as oral or non-oral by the Clinical Research scientist prior to database lock (oral AE's were AEs effecting tissues associated with the oral cavity extending from the labial mucosa to the pharyngeal area).

Participant Flow

All participants were recruited at one center in the United States.

A total of 155 participants were screened, of which first 31 eligible participants with complete upper dentures were included in Phase 1 (food removal testing). Out of 155 participants, 152 were randomized in Phase 2 (oral soft tissue and dermal assessment). 3 participants were not randomized as 2 were screened failure and 1 withdrew from study.

PRIMARY outcome

Timeframe: up to 14 days

Population: Analysis for this outcome was performed on safety population which included all the participants who were randomized and received treatment at least once during the study. No inferential statistical analysis has been performed for this outcome.

SECONDARY outcome

Timeframe: Day 7, Day 14

Population: Analysis for this outcome was performed on safety population which included all participants who were randomized and received treatment at least once during the study.

Dermal assessment performed by a suitably qualified dermatologist on the front and back of the participant's dominant hand (hand with which participant used to hold the wipe during use) using skin irritation score that range from 0-4 as follows: 0 = no apparent cutaneous involvement, 0.5= equivocal reaction, 1= slight erythema with or without oedema, 2= moderate erythema, oedema with or without papules, 3= severe erythema, oedema with or without papules, 4= severe erythema, oedema with vesicles or blisters. Any site where skin irritation was scored ≥2, was visually assessed and reported.

SECONDARY outcome

Timeframe: Day 7

Population: Analysis for this outcome was performed on safety population which included all participants who were randomized and received treatment at least once during the study.

All the participants supplied with a consumer acceptability questionnaire (Question \[Q\] 1 to 4) to complete immediately before \& after their first use of treatment at home after eating a meal. The number of participants with individual score was reported. After eating \& before cleaning denture: Q1= how fresh does denture feel?, Q2= how clean does denture feel?; Look in the mirror and smile, now answer the following questions: Q3= after eating \& before cleaning, how clean does denture/smile look ?, Q4= after removing \& cleaning denture, how fresh does denture feel?, Q5= after removing \& cleaning denture, run your tongue over denture teeth, how clean does denture feel?, Q6= after removing \& cleaning denture, how clean does denture/smile look?, Q7= after removing \& cleaning denture, how satisfied are you with amount of debris removed? All questions were scored as follows for respective parameter(fresh/clean/satisfied): 0=Not at all, 1=slightly, 2=moderately, 3=very, 4=extremely.
