About this study

Official title: A Randomised Open Label Placebo Controlled Study to Evaluate Fractional Collagen Synthesis in Keloids and Identify Biomarkers of Keloid Biology for Potential Application in Future Clinical Trials

This is a 3-arm randomised clinical enabling study, with no investigational product. Keloid patients who are scheduled for surgical excision of one or more keloid scars (up to nine) will be recruited to the study. The aim is to investigate how collagen synthesis within keloid scars is affected by the current approved steroid treatment for keloids, triamcinolone acetonide (TAC). The primary endpoint will be fractional collagen synthesis in keloids which have received intra-lesional injections of TAC, placebo or no treatment prior to their removal. Fractional collagen synthesis will be determined using an established isotope/mass spectrometric technique which measures levels of deuterium incorporation into collagen following administration of heavy water to the subject. In addition; keloid tissue samples will be evaluated post surgery to identify further biomarkers of extracellular matrix synthesis and degradation for application in future clinical studies. Subjects will complete a screening visit and will then be randomised to receive three intra-lesional injections of TAC or placebo, or no treatment, at an interval of 2-3 weeks. Subjects will be randomised to different treatment sequences depending on the number of keloids they have scheduled for surgery, in such a way that subjects with multiple keloids will receive different arms of study treatment in their different keloids. Planned surgery for removal of their keloid(s) will be performed at week 6-8. All subjects will receive daily heavy water (Deuterium oxide) administration (twice daily or thrice daily as directed), with the first dose being taken at the Week 2 clinic visit and the final dose being taken on the day prior to surgery. A follow-up visit will be conducted at 1-4 weeks post-surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Triamcinolone acetonideDrug

    Triamcinolone acetonide will be administered as intra-lesional injection in the keloid(s).

  • PlaceboDrug

    Placebo will supplied as commercial injectable saline, and will be administered as intra-lesional injection in the keloid(s).

What is being measured

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

  1. Fractional synthesis of collagen in keloid scars

    Post surgical excision of keloids, tissue samples will be obtained by snap frozen biopsies. Fractional synthesis of collagen (that is, the fraction of the collagen that is newly synthesised during the labelling period) will be determined using mass spectrometry which measures the levels of deuterium incorporation into hydroxyproline or alanine in the collagen from the excised tissue samples, following administration of heavy water (Deuterium oxide) to the subject

    Measured: Week 6-8

Secondary outcomes (4)
  1. Keloid scar volume before first dose and immediately prior to surgery

    For each keloid under evaluation, the keloid volume will be measured using three-dimensional (3D) photography

    Measured: Day 1 and Week 6-8

  2. Keloid scar surface area before first dose and immediately prior to surgery

    For each keloid under evaluation, the keloid surface area will be measured using 3D photography

    Measured: Day 1 and Week 6-8

  3. Keloid scar length and height before first dose and immediately prior to surgery

    For each keloid under evaluation, the keloid length and height will be measured using 3D photography

    Measured: Day 1 and Week 6-8

  4. Keloid scar vascularity before first dose and immediately prior to surgery

    For each keloid under evaluation, the keloid vascularity will be measured by laser Doppler

    Measured: Day 1 and Week 6-8

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Triamcinolone acetonide in people with Fibrosis, run by GlaxoSmithKline at 1 site in United Kingdom.

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 5 inclusion and 11 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: stopped early, as of the sponsor's last update on 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Temporary hold on recruitment during staff changes at the site). Results are not available in the source record.

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?

Fractional synthesis of collagen in keloid scars (time frame: Week 6-8). 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 15 May 2017.
