Cutaneous Effects of Cryogen Spray Cooling
A Phase 1 study testing Cutaneous Effects of Cryogen Spray Cooling in people with Pain, run by University of California, Irvine at 1 site in United States.
Trial summary
Cryogen Spray Cooling spurt is applied to the skin surface immediately before laser exposure. As liquid cryogen rapidly evaporates, the superficial skin temperature is reduced as a result of supplying the latent heat of vaporization. Read more about this study

About this study
Cryogen Spray Cooling spurt is applied to the skin surface immediately before laser exposure. As liquid cryogen rapidly evaporates, the superficial skin temperature is reduced as a result of supplying the latent heat of vaporization. Tetrafluoroethane, an environmentally compatible, non-toxic, non-flammable freon substitute, has been demonstrated in multiple studies to be a safe and effective cooling agent and is the only cryogenic compound currently approved for dermatologic use by the Food and Drug Administration.
Read the detailed description
The researcher can use laser treatment in combination with Cryogen Spray Cooling. The specific aim of this study is to characterize the clinical cutaneous effects of varying spurt durations and spurt delivery patterns that spurt durations of 100 ms or less will result in a very low incidence (less than 2%) of clinical skin effects (redness, blistering, local skin allergic reaction or skin discoloration) in any skin type.
Researchers can use Cryogen Spray Cooling to protect the skin epidermis during laser therapy to decrease treatment pain, allow safe treatment of darker skin types, and safe use of high laser fluences. Cryogen Spray Cooling with Tetrafluoroethane has been incorporated into many Food and Drug Administration approved, commercially available laser devices currently used for treatment of vascular lesions, hair removal and non-ablative skin rejuvenation.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Tetrafluoroethane, an environmentally compatible, non-toxic, non-flammable freon substitute, has been demonstrated in multiple studies to be a safe and effective cooling agent and is the only cryogenic compound currently approved for dermatologic use by the Food and Drug Administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Cutaneous Effects of Cryogen Spray Cooling in people with Pain, run by University of California, Irvine at 1 site in United States.
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 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 1 Nov 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 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.
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?
Skin cooling during laser treatment (time frame: 1 minute). 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 1 Nov 2022.
