Trial summary

Cutaneous Lupus erythematosus (CLE) is a chronic autoimmune connective tissue disease with a prevalence of 14.6 - 73.2/100,000, predominantly in women in mid adulthood. Cutaneous lesions occur in about 75-80% of patients with systemic lupus erythematodes.These lesions unfortunately and invariably lead to significant… Read more about this study

About this study

Official title: Within-subject, Investigator Initiated, Single-blind, Single-centre, Randomized Clinical Trial Investigating the Efficacy of Fractional Er:YAG Laser in Lupus Erythematosus Scars

Cutaneous Lupus erythematosus (CLE) is a chronic autoimmune connective tissue disease with a prevalence of 14.6 - 73.2/100,000, predominantly in women in mid adulthood. Cutaneous lesions occur in about 75-80% of patients with systemic lupus erythematodes.These lesions unfortunately and invariably lead to significant scarring and postinflammatory hypo- and hyperpigmentation.

Several studies have reported that laser treatments in patients with CLE have a positive effect and safety. However, only few case reports exist about the effect of ablative lasers such as Carbon Dioxide (CO2) and Erbium-doped Yttrium Aluminum Garnet (Er:YAG) lasers in CLE scarring.

Although no study shows a flare-up of CLE after laser treatment of the scars, many physicians are afraid of treating these often stigmatizing scars. Considering the huge psychological impact of facial scaring on quality of life, it is essential to explore and assess the value of already well-established treatment options for the management of scars also in patients with cutaneous lupus erythematodes.

Hereby the study seeks the subjective and objective improvement of the CLE-scars after treatment with fractional Er:YAG laser compared to control (untreated) areas.

What is being measured

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

  1. Average reduction of POSAS scar severity measure.

    Average reduction from baseline of Patient and Observer Scar Assessment Scale (POSAS), ranging from 12 to 120 with higher score indicating a worst condition.

    Measured: 24 weeks

Secondary outcomes (4)
  1. Cumulative incidence of localized disease flare-up.

    Cumulative incidence of disease flare-up defined according to localized Revised Cutaneous Lupus Erythematosus Disease Area and Severity Index (RCLASI) difference from baseline of 1 point or above. The localized RCLASI ranges from 0 to 13, with higher scores indicating a worst local disease activity.

    Measured: 4, 8, 12, 16 and 24 weeks

  2. Overall average reduction of POSAS scar severity measure.

    Overall average reduction from baseline of Patient and Observer Scar Assessment Scale (POSAS), ranging from 12 to 120 with higher score indicating a worst condition.

    Measured: 16 and 24 weeks

  3. Overall average scar improvement according to physician global assessment.

    Overall average scar improvement from baseline according to a 6-point Physician Global Assessment (PGA) scale, based on before-after pictures of lesions assessment, ranging from 1 to 6, with higher scores indicating a better outcome.

    Measured: 4, 8, 12, 16 and 24 weeks

  4. Average patient's satisfaction.

    Average patient's satisfaction score as assessed by a 9-point anchored visual analogue scale (VAS), ranging from -4 to +4, with negative scores indicating a worsening of condition compared to the untreated control scar, with 0 indicating no difference and with positive scores indicating an improvement.

    Measured: 16 and 24 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Er:YAG laser in people with Lupus Erythematosus, Cutaneous, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

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 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: withdrawn, as of the sponsor's last update on 6 Dec 2024. 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 Switzerland. 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. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Average reduction of POSAS scar severity measure. (time frame: 24 weeks). 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 6 Dec 2024.
