Trial summary

Methyl aminolaevulinate photodynamic therapy (MAL-PDT) is advantageous in that it has few cosmetic side effects and minimises patient discomfort. However, its relatively low efficacy prevents its application to the treatment of actinic cheilitis(AC). Read more about this study

About this study

Official title: A Randomized, Prospective Study Comparing Methyl Aminolaevulinate Photodynamic Therapy With and Without Er:YAG Ablative Fractional Laser Treatment for Actinic Cheilitis

Methyl aminolaevulinate photodynamic therapy (MAL-PDT) is advantageous in that it has few cosmetic side effects and minimises patient discomfort. However, its relatively low efficacy prevents its application to the treatment of actinic cheilitis(AC). Er:YAG ablative fractional laser (AFL) treatment removes the stratum corneum to increase MAL uptake and may improve efficacy. However, no studies have directly compared the efficacy of MAL-PDT with and without Er:YAG AFL in treating AC

Read the detailed description

Actinic cheilitis (AC) is a keratinocytic neoplasm of the lip, especially the lower lip, is confined to the epidermis, and results from chronic or excessive ultraviolet exposure. AC is an early manifestation of lip squamous cell carcinoma (SCC), and SCC of the lip is usually associated with an identifiable pre-existent AC. Furthermore, the likelihood that AC will progress to SCC is higher than actinic keratosis (AK). Consequently, early identification and treatment of AC is recommended. PDT involves the activation of a photosensitizer by irradiation with 400- to 700-nm light to create cytotoxic oxygen and free radicals that kill dysplastic cells.

Methyl aminolaevulinate photodynamic therapy (MAL-PDT) is advantageous in that it has few cosmetic side effects and minimises patient discomfort. However, its relatively low efficacy prevents its application to the treatment of actinic cheilitis(AC).

Erbium:yttrium-aluminium-garnet (Er:YAG) ablative fractional laser (AFL) therapy has been used frequently to improve treatment efficacy of PDT. Er:YAG AFL can ablate stratum corneum with minimal penetration depth and producing minimal thermal injury. This approach creates microscopic vertical holes in the ablated tissue, surrounded by thin layers of coagulated tissue. Er:YAG AFL does not injure the entire thickness of the epidermis; therefore, healing times are minimised. Erbium:yttrium-aluminium-garnet (Er:YAG) ablative fractional laser (AFL) has been proven in recent studies to facilitate the delivery and uptake of topical MAL deep into the skin, enhancing porphyrin synthesis and photodynamic activation.

The aim of our study was to compare efficacy, recurrence rate, cosmetic outcome, and safety between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT in patients with AC.

What participants receive

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

  • Er:YAG AFL-PDTDrug

    Also called Er:YAG ablative fractional laser-assisted MAL-PDT

    Er:YAG AFL was performed with 350 µm ablation depth, level 1 coagulation, 22% treatment density, and a single pulse. MAL cream was then applied under occlusion for 3 hrs and illuminated with a red light-emitting diode light at 37 J/cm2.

  • MAL-PDTDrug

    Also called methyl aminolaevulinate-Photodynamic therapy

    a 1-mm thick layer of MAL (16% Metvix® cream, PhotoCure ASA, Oslo, Norway) was applied to the lesion and to 5 mm of surrounding healthy tissue. The area was covered with an occlusive dressing (Tegaderm, 3M, Saint Paul, MN, US) for 3 hours, after which the remaining cream was removed with saline gauze, and the red fluorescence of porphyrins was visualized with Wood's light. Each treatment area was then separately illuminated with red light-emitting diode (LED) lamps (Aktilite CL128; Galderma, Bruchsal, Germany) with peak emission at 632 nm and total light dose of 37 J cm-2. Areas scheduled to receive MAL-PDT received the second treatment 7 days later.

What is being measured

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

  1. Difference the efficacy between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT.

    Lesion response was classified as either complete (complete disappearance of the lesion) or incomplete (incomplete disappearance) on the basis of visual examination and palpation. The response of each lesion was clinically evaluated

    Measured: Efficacy was evaluated at 3 months and 12 months after treatment

Secondary outcomes (1)
  1. Difference of the cosmetic outcomes between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT.

    It was graded using a 4-point scale: excellent (only slight occurrence of redness or change in pigmentation), good (moderate redness or change in pigmentation), fair (slight-to-moderate scarring, atrophy, or induration), or poor (extensive scarring, atrophy, or induration)

    Measured: Cosmetic outcome was assessed by each investigator for all lesions that achieved a complete response at 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Er:YAG AFL-PDT and MAL-PDT in people with Actinic Cheilitis, run by Dong-A University at 1 site in South Korea.

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 1 inclusion and 10 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 23 Jul 2014. 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 South Korea. 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.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Difference the efficacy between Er:YAG AFL-assisted MAL-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT. (time frame: Efficacy was evaluated at 3 months and 12 months after treatment). 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 23 Jul 2014.
