Official title: Efficacy and Safety of Metvix® Natural Daylight Photodynamic Therapy Versus Conventional Metvix® Photodynamic Therapy in Subject With Mild Actinic Keratoses

The main objective of this study is to compare efficacy and safety of Metvix® natural daylight photodynamic therapy with those of Metvix® conventional photodynamic therapy in subjects with mild actinic keratoses (intra-individual comparison)

Being tested

What participants receive

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

  • Metvix®Drug

  • Photodynamic Therapy Blue lightProcedure or surgery

    Photodynamic therapy (PDT) is a medical treatment that utilizes a photosensitizing molecule (Metvix) and a blue light source to activate the applied drug

  • Photodynamic Therapy DaylightProcedure or surgery

    Photodynamic therapy (PDT) is a medical treatment that utilizes a photosensitizing molecule (Metvix) and a the day light to activate the applied drug

What is being measured

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

  1. Mean Change From Baseline in Total Number of Treated Mild Lesions Per Side at Week 12

    The number of lesions is assessed at baseline (before treatment) and 12 weeks later.

    The difference in lesions is recorded for each patient. The mean of disappeared lesions are then calculated for all patients.

    Measured: Baseline and Week 12

Secondary outcomes (3)
  1. Pain Assesment

    Pain assesment with a VAS Pain scale

    Visual analog scale [VAS] is a continuous scale comprised of a horizontal scale of 10 cm length . The scale is anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 10).

    Measured: at inclusion (after treatment)

  2. Lesions Disappearance Rate at 1 Months From Baseline.

    The number of lesions is assessed at baseline (before treatment) and 1 month later.

    The difference in lesions is recorded for each patient. The rate is the quotient: " difference in lesions between baseline and at 1 month "/nubmer of lesions at baseline

    Measured: 0(baseline),1 month

  3. Lesions Disappearance Rate at 6 Months From Baseline.

    The number of lesions is assessed at baseline (before treatment) and 6 month later.

    The difference in lesions is recorded for each patient. The rate is the quotient: " difference in lesions between baseline and at 6 month "/nubmer of lesions at baseline

    Measured: 0(baseline), 6 month

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Metvix®, Photodynamic Therapy Blue light and Photodynamic Therapy Daylight in people with Actinic Keratoses, run by University Hospital, Limoges at 1 site in France.

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 2 inclusion and 3 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 29 Jul 2025. 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 France. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Mean Change From Baseline in Total Number of Treated Mild Lesions Per Side at Week 12 (time frame: Baseline and Week 12). 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 NCT02373371, 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 29 Jul 2025.
