What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of Dermal Response Score at 15-30 Minutes Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 15-30 minutes following patch removal on Day 2 post 24 hrs of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 2 (15-30 minutes post patch removal)

  2. Frequency of Dermal Response Score at 24 Hours Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 24 hours following patch removal on Day 3 post 48 hrs of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 3 (24 hours post patch removal)

  3. Frequency of Dermal Response Score at 48 Hours Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 48 hours following patch removal on Day 4 post 72 hours of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 4 (48 hours post patch removal)

  4. Average Dermal Response Score at 30 Minutes Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 15-30 minutes following patch removal on Day 2 post 24 hours of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 2 (15-30 minutes post patch removal)

  5. Average Dermal Response Score at 24 Hours Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 24 hours following patch removal on Day 3 post 48 hours of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 3 (24 hours post patch removal)

  6. Average Dermal Response Score at 48 Hours Post Patch Removal

    Product tolerability was assessed by Dermal Response Score. Test sites were evaluated 48 hours following patch removal on Day 4 post 72 hours of patch application. Response score from 0 to 7; 0= No evidence of irritation, 1= Minimal erythema, barely perceptible, 2= Definite erythema, readily visible; minimal edema or minimal papular response, 3= Erythema and papules, 4= Definite edema, 5= Erythema, edema and papules, 6= Vesicular eruption, 7= Strong reaction spreading beyond test site.

    Measured: At Day 4 (48 hours post patch removal)

Secondary outcomes (1)
  1. Number of Participants With Combined Skin Irritation (Dermal Response) Scores at 30 Minutes, 24 Hours and 48 Hours Post Patch Removal

    A trained assessor assessed all patch sites.Following scores were used to express response observed at time of examination:0=No evidence of irritation,1=Minimal erythema;barely perceptible,2=Definite erythema,readily visible;or minimal edema; or minimal papular response,3=Erythema and papules,4=Definite edema,5=Erythema, edema,and papules,6=Vesicular eruption,7=Strong reaction spreading beyond test site.Other features indicative irritation (Superficial irritation) scores were:GradeA/Score0=Slight glazed appearance,GradeB/Score1=Marked glazing,GradeC/Score2=Glazing with peeling and cracking,GradeF/Score3=Glazing with fissures,Grade G/Score 3=Film of dried serous exudate covering all or portion of patch,Grade H/Score3=Small petechial erosions and/or scabs.The letter grades were converted to scores.Superficial irritation scores were only provided if there was a dermal response score >0.No effect is 0 score(i.e. no evidence).Full Range 0-10.Lower score indicates better product tolerabily

    Measured: At Day 2 (15-30 minutes), Day 3 (24 hours) and Day 4 (48 hours) post patch removal

Questions about this trial

What is this clinical trial studying?

A study testing Experimental Daily Defense Serum A, Experimental Daily Defense Serum C and Experimental Daily Defense Serum G in people with Skin Care, run by GlaxoSmithKline at 2 sites in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Sep 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of Dermal Response Score at 15-30 Minutes Post Patch Removal (time frame: At Day 2 (15-30 minutes post patch removal)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jan 2019.
