What participants receive

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

  • Alma - Harmony XL LaserDevice

    Also called Modified Alma Laser Harmony Neodymium-Doped Yttrium Aluminium Garnet (Nd:YAG) Module

    The Erbium YAG laser at a 2940nm wavelength is used for ablative laser resurfacing as well as treating acne scars.

Study groups in NCT03333759
Study groupRoleWhat they receive
Laser TreatmentExperimentalPatients will receive one laser treatment (week 0) with the Erbium YAG laser at a 2940nm wavelength (Alma - Harmony XL Laser) and parameters corresponding with their acne scar severity. They will then return to the clinic 1, 4 and 8 weeks (7, 30, and 56 days + 7 days) after the treatment for their scars to be evaluated under optical coherence tomography. Laser parameters are as follows: iPixelEr 2940nm Erbium:YAG Module: mild scars: 7 by 7 (7X7) mm tip, energy 1400-1600 millijoules/P (mJ), pulse energy 5 Hz, 2-6 stacks, pulse mode L, 2-3 passes, 10% overlap moderate scars: 7X7 mm tip, energy 1600-1800 mJ/P, pulse energy 5 Hz, 2-6 stacks, pulse mode L, 2-3 passes, 10% overlap severe scars: 7X7 mm tip, 1800-2000 mJ/P, pulse energy 5 Hz, 2-6 stacks, pulse mode L, 2-3 passes, 10% overlap

What is being measured

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

  1. Change in blood flow

    Optical coherence tomography (OCT) will be used to quantitatively measure changes in facial atrophic acne scars in terms of blood flow (proportion of signals with strong dynamic signal (%)/depth (mm)).

    Measured: During 8 weeks

  2. Change in epidermal thickness

    Optical coherence tomography (OCT) will be used to quantitatively measure changes in facial atrophic acne scars in terms of epidermal thickness (mm).

    Measured: During 8 weeks

  3. Change in collagen content

    OCT will be used to qualitatively measure changes in facial atrophic acne scars in terms of collagen content. Collagen content will be measured in terms of brightness of OCT scan. Areas of skin that contain collagen tend to be brighter (more white in color) whereas areas with less collagen content tend to be darker.

    Measured: During 8 weeks

  4. Change in skin roughness

    OCT will be used to quantitatively measure changes in facial atrophic acne scars in terms of skin roughness (µm).

    Measured: During 8 weeks

Secondary outcomes (2)
  1. The Patient Scar Assessment Scale

    Scale (1-10) used to qualitatively monitor treatment and changes in scars by the patient.

    Measured: During 8 weeks

  2. The Observer Scar Assessment Scale

    Scale (1-10) used to qualitatively monitor treatment and changes in scars by the dermatologist.

    Measured: During 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Alma - Harmony XL Laser in people with Acne Vulgaris, run by University of Miami at 1 site in United States.

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 3 inclusion and 8 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: withdrawn, as of the sponsor's last update on 26 Jul 2018. 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 States. 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?

Change in blood flow (time frame: During 8 weeks). The study lists 4 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 26 Jul 2018.
