About this study

Official title: Photoaging Reversing After Picosecond Laser With Diffractive Focus Lens Assessed by Cellular Resolution Optical Coherent Tomography in Asian Patient With Melasma

Background Melasma is a commonly acquired hypermelanosis that affects facial sun exposed areas, most commonly in Asians and other darker skin type females. Recent evidence has demonstrated melasma to be a photoaging disorder. The histological findings of melasma are similar to photoaging and include solar elastosis, increased mast cells and sebaceous glands, as well as increased vascularization. Pendulous active melanocytes with weakened basal membranes, and changes in nuclear morphology and chromatin texture of adjacent basal keratinocytes also seemed to be a characteristic feature of melasma.

Objectives:

Read more

To compare the difference of photoaging features of melasma skin and normal skin by optical coherence tomography (ApolloVue® S100 Image System, a 510(K) class II medical device) and reversal of photoaing features by 755nm picosecond alexandrite laser with diffractive lens.

Methodology:

We enroll 20 adults with facial melasma. The patients received 755nm picosecond alexandrite laser with diffractive lens array over whole face at W0, W4, and W8. Evaluation with VISIA, optical coherence tomography, Cutometer MPA580 at W4, W8, W12. All the patients will be instructed with use of moisturizer, gentle cleaning, and sunscreen use.

Anticipated results and applications:

This study expects to

  1. understand the role of 755nm picosecond alexandrite laser with diffractive lens of reversal of photodamage and improving the melasma by evaluation with optical coherence tomography and other noninvasive methods.
  2. Set evidence based guidance for melasma treatment and set the protocol or clinical path.

What is being measured

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

  1. Clinical improvement of melasma

    Clinical improvement of melasma after picosecond laser treatment will be assessed by both physician and patient at week 0, week 4, week 8, and week 12.

    Measured: 4 weeks

  2. Improvement of MASI score

    Improvement of melasma after picosecond laser treatment will be assessed using MASI score that will be calculated according to the image taken by VISIA at week 0, week 4, week 8, and week 12.

    Measured: 4 weeks

  3. Improvement of hydration, TEWL, viscoelasticity, or melanin and erythema index

    Improvement of melasma after picosecond laser treatment will be assessed using Cutometer® MPA 580 at week 0, week 4, week 8, and week 12.

    Measured: 4 weeks

  4. Number of subjects with clear tissue characteristics of melasma and/or normal skin in tomograms

    Number of subjects with clear tissue characteristics of tomograms will be compared to that with unclear tissue characteristics to identify the effect of the OCT on scanning melasma at study completion.

    Measured: 4 weeks

Secondary outcomes (1)
  1. Number of subjects with the distinction between melasma and normal skin in tomograms

    Number of subjects with the distinction between melasma and normal skin in tomograms will be compared to that with no distinction to verify the specific diseases that can be distinguished from others by the OCT at study completion.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing PicoSure 755nm picosecond alexandrite laser with diffractive lens, ApolloVue® S100 Image System and Cutometer® dual MPA 580 in people with Melasma, run by China Medical University Hospital at 1 site in Taiwan.

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 5 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: finished, as of the sponsor's last update on 20 Jul 2022. 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 Taiwan. 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?

What does the primary outcome measure?

Clinical improvement of melasma (time frame: 4 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?

On the ClinicalTrials.gov record for NCT04602819, which also lists 1 linked publication.

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 20 Jul 2022.
