What participants receive

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

  • Dermal HandpieceDevice

    Radiofrequency (RF) will travel through the RF generator through the electrodes and into the dermal layer beneath the surface of the skin. The microneedles of the dermal cartridges coupled with the thermal heat will stimulate neocollagenesis and neoelastosis, aiding in the reduction of submental laxity.

Questions about this trial

What is this clinical trial studying?

A study testing Dermal Handpiece in people with Skin Laxity, run by University of Texas Southwestern Medical Center at 1 site in United States.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 28 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 19 Dec 2023. 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?

Yes. Results are posted in the registry (first posted 19 Dec 2023). 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?

Percent Change From Baseline of Soft Tissue Surface Area (time frame: Month 3 and Month 6 Follow Up). The study lists 5 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 19 Dec 2023.
