About this study

Official title: Treatment of Acne Scars With Fractional CO2 Laser Versus Radio-frequency Microneedling: A Randomized Controlled Trial

The study is a prospective, randomized, controlled, intra-person split-face trial with blinded evaluations. The objective is to compare efficacy and adverse effects of ablative fractional CO2 laser resurfacing versus radio-frequency microneedling for treatment of atrophic acne scars in the facial area. Two comparable areas with acne scars on each side of the face are treated. One area will be treated with fractional CO2 laser and the other area with radio-frequency microneedling.

Outcome measures will be assessed by blinded investigators and included subjects at baseline before treatment and at follow-up visits 2-4 days and 1 and 3 months post-treatment. On-site assessment and OCT will be performed at the time of the visits. OCT scans will be offered to the subjects and are optional. Clinical photos are used for documentation.

15 participants will be recruited. The participants will be recruited to enter the trial in the clinic by investigators at the Department of Dermatology, Bispebjerg Hospital, and must meet the inclusion criteria (at least 18 years of age, acne scars in the facial area, comparable atrophic acne scars on each side of the face, fitzpatrick skintype I-III) to be eligible to enter the study. No personal remuneration will be awarded the investigators. None of the collaborators have any personal economic interest in the study. Participants will not receive remuneration.

All treatments are performed at the Department of Bispebjerg Hospital and patients are covered by the Hospital's patient insurance.

The declaration of Helsinki will be respected as well as the standards of good clinical research. Respect for privacy as well as physically and mentally integrity of the participants will be maintained. The study will be performed in accordance with Danish Health care authorities.

Questions about this trial

What is this clinical trial studying?

A study testing Ablative fractional CO2 laser resurfacing/Radio-frequency microneedling in people with Acne Scars - Mixed Atrophic and Hypertrophic, run by Aarhus University Hospital at 1 site in Denmark.

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.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Feb 2020. 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 Denmark. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Merete Hædersdal, MD,PhD,DMSc (+4520416746, merete.haedersdal@regionh.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Asymmetry (scar texture, erythema, pigmentation) (time frame: 3 months). 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 5 Feb 2020.
