Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to examine both the genetic profile and the biomarkers implicated in keloid scar formation.

Hypothesis:

1. Differences in the genetic profiles of lesional and non-lesional skin contribute a given population's propensity to develop keloids
2. Differences in biomolecules expressed in subjects with and without keloids can help predict keloid occurrence and severity
3. Biomarker analysis will provide useful insights for future targeted therapies for keloid scars

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objectives:

1. Determine gene expression profiles of keloid scar tissue using samples collected longitudinally
2. Define and compare the molecular biomarkers of keloid scars in keloid (lesional) and non-lesional skin biopsies and serum samples from adult subjects

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

Baseline lesional and non-lesional biopsies and re-biopsy 6-8 weeks later with intralesional triamcinolone injections at 9-10, 12-16, and 24-32 weeks.

Group Type ACTIVE_COMPARATOR

Biopsy and/or triamcinolone injection

Intervention Type PROCEDURE

Subjects will have their blood drawn during the first study visit. Subsequently, a punch biopsy and/or triamcinolone injection will be given based on group timeline.

Group 2

Baseline lesional biopsy and re-biopsy at 6-8 weeks with intralesional triamcinolone injections at 3-4, 9-10, 12-16, and 24-32 weeks

Group Type ACTIVE_COMPARATOR

Biopsy and/or triamcinolone injection

Intervention Type PROCEDURE

Subjects will have their blood drawn during the first study visit. Subsequently, a punch biopsy and/or triamcinolone injection will be given based on group timeline.

Group 3

Baseline lesional and non-lesional biopsy and re-biopsy 3-4 months later with intralesional triamcinolone injections at 18-20 and 24-32 weeks.

Group Type ACTIVE_COMPARATOR

Biopsy and/or triamcinolone injection

Intervention Type PROCEDURE

Subjects will have their blood drawn during the first study visit. Subsequently, a punch biopsy and/or triamcinolone injection will be given based on group timeline.

Group 4

Baseline lesional biopsy and re-biopsy at 3-4 months with intralesional triamcinolone injections at 3-4, 6-8, 18-20 and 24-32 weeks.

Group Type ACTIVE_COMPARATOR

Biopsy and/or triamcinolone injection

Intervention Type PROCEDURE

Subjects will have their blood drawn during the first study visit. Subsequently, a punch biopsy and/or triamcinolone injection will be given based on group timeline.

Group 5

Normal patient skin (surgical or adjacent to other biopsy) from subjects with no self-reported history of keloids.

Group Type ACTIVE_COMPARATOR

Biopsy and/or triamcinolone injection

Intervention Type PROCEDURE

Subjects will have their blood drawn during the first study visit. Subsequently, a punch biopsy and/or triamcinolone injection will be given based on group timeline.

Earlobe Keloid

Complete excision of an earlobe keloid measuring \> 10mm will be taken.

Group Type OTHER

Excisional Biopsy

Intervention Type PROCEDURE

Complete excision of an earlobe keloid will be taken.
