Keloid Tissue Bank

November 14, 2014 updated by: Tirgan, Michael H., M.D.

Keloid Tissue Bank - Longitudinal Clinical Data Repository; A Genomic and Molecular Research to Identifying Molecular Markers and Signal Transduction Pathways in Keloid; and Correlations With the Natural History of the Disease.

Much progress in treatment of various tumors has been made in the laboratory and the results have been brought back to the patients, i.e. from bench to bedside. This trial intends to collect samples of keloid tissue from patients and study them in laboratory. Such a research may help us with finding better treatments for keloid.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

To aims of this trial are:

  1. To prospectively collect keloid and normal skin tissue samples from patients with keloid by performing keloid tissue biopsy and biopsy of uninvolved skin.
  2. To collect blood and/or saliva for genomics, proteomics, tissue culture, flow cytometery and other keloid investigational studies.
  3. To collect any keloid tissue that has been previously removed from the patient (unrelated to enrollment on this study).
  4. To prospectively collect keloid tissue from patients who are undergoing a planned surgical removal of their keloids.
  5. To evaluate keloid histology, genomics, proteomics, molecular markers, cytokines, growth factors receptors, ligands and signal transduction pathways within keloid tissue in order to find druggable targets.
  6. To prospectively follow the patients and correlate patient demographics and natural history of the disease, response to the past and future treatments with the genomic and molecular maker profiles.
  7. To culture nucleated blood cells from keloid patients in order to determine the genomics of this disease as well as learning about potential presence of keloid stem cell in peripheral blood. To use flow cytometry as well as other technology to search for circulating keloid stem cells in peripheral blood.
  8. To test in vitro:

A- The effect of small molecule kinase inhibitors on the activation of wild-type and mutant kinases.

B- The effects of various drugs that inhibit ligands, receptors or pathways.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patient with a clinical diagnosis of keloid who are 13 years or older.

Description

Inclusion Criteria:

  1. Patients must have clinically confirmed diagnosis of keloid
  2. Signed consent form; parent or a legal guardian should consent for children and those under age of 18.
  3. Have at least one paraffin block of excess keloid tissue that has been removed in the past; or is planned to be removed in future.
  4. Able and willing to undergo a keloid biopsy (optional)
  5. Able and willing to undergo biopsy of their normal appearing skin (optional, minimum age 18).

Exclusion Criteria:

  1. Individuals who are mentally challenged, who cannot consent to participate in this study.
  2. Psychological Illness that may result in non-compliance with the procedure and the required follow up.
  3. Known allergy to lidocaine or other local anesthetics.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Patients with keloid
All patients will have a clinical diagnosis of keloid and will consent to participate in this study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of cases with a genetic mutations within the study cohort will be measured.
Time Frame: Three years
Prevalence of various biomarkers and/or mutations will be determined and co-related with the clinical presentation of the disease.
Three years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2012

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 1, 2018

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
