About this study

Whole-body hyperthermia (WBH) to an internal temperature of 38.5 C (101.3 F) using an infrared heating device has been associated with significant reductions in clinical depression. This prior work utilized a WBH medical device that is manufactured in Germany, is not FDA approved, and is not widely available. The goal of this initial pilot project is to ascertain whether an infrared sauna, the Curve Sauna Dome, which is readily accessible (i.e., can be purchased by consumers in the US) can be used to conduct WBH that achieves an internal body temperature of of 101.3 F in healthy volunteers.

Read the detailed description

Prior work has demonstrated that whole body hyperthermia (WBH) to an internal temperature of 38.5 C (101.3 F) using an infrared heating device is associated with significant reductions in clinical depression. This prior work utilized a Heckel WBH device, a medical device manufactured in Germany that is not FDA-approved and that is not widely available. The goal of this pilot project is to ascertain whether the Curve Sauna Dome, an infrared sauna that is readily accessible (i.e., can be purchased by consumers in the US) can be used to conduct WBH that achieves an internal body temperature of of 38.5 C (101.3 F) in healthy volunteers.

What participants receive

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

  • Curve Sauna DomeDevice

    All participants receive WBH for 80-110 minutes in an infrared sauna. Participants lay supine in the sauna during this time, and their head is external to the sauna.

What is being measured

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

  1. Sauna Curve Dome successfully induces a core body temperature of 101.3

    Achieving core body temperature of 101.3 F using a rectal temperature assessment method

    Measured: Duration of time in Curve Sauna Dome, up to ~110 minutes

  2. Adverse Events Causing Cessation of Curve Sauna Dome Session

    Any adverse event causing stopping of sauna session prior to achieving 101.3 F

    Measured: Duration of time in Curve Sauna Dome, up to ~110 minutes

Secondary outcomes (1)
  1. Time to Achieve Core Body Temperature of 101.3 F in Curve Sauna Dome

    Amount of time before participant achieves core body temperature of 101.3 F using a rectal temperature assessment method

    Measured: Duration of time in Curve Sauna Dome, up to ~110 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Curve Sauna Dome in people with Core Body Temperature 101.3 F, run by University of California, San Francisco 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 9 inclusion and 18 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 2 Feb 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?

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?

Sauna Curve Dome successfully induces a core body temperature of 101.3 (time frame: Duration of time in Curve Sauna Dome, up to ~110 minutes). The study lists 2 primary outcomes in all. 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 NCT04249700, 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 2 Feb 2023.
