An interventional study of Hyperthermia in Safety Study, sponsored by Marc Abreu. Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-21.
Sponsored by Marc Abreu · Not applicable, Interventional, and Treatment
The Abreu BTT 700 Temperature Management System (TMS) is a device that gently raises the body temperature of the participant to a fever-range level in a controlled setting. There will be one study treatment session. with the TMS system and four safety assessments: before the session, about two hours afterward, on the next day, and again on the third day after the session. Your participation in the study will last about three days in total. An electrocardiogram (ECG - traces the electrical activity of the heart) will be performed during screening. This is not a randomized or blinded study -- all participants will receive the same study treatment. The TMS system has been previously used in other settings, but this study is designed specifically to collect safety data in adult volunteers.
Participants are being asked to take part because they are healthy adults between the ages of 18 and 65 and have no history of any heart, cancer, or neurological disorders. Participation in this study will help researchers understand how healthy people respond to this technology before it is tested in people with specific medical conditions.
Voluntary Participation: Taking part in this study is completely voluntary. Volunteers do not have to participate and may withdraw at any time. Stopping to participate in the study will not result in any penalties or loss of benefits.
Benefits, Compensation, and Risk: Subjects may not receive any direct benefit from participating in this study. However, participation will help researchers develop safer treatments for others in the future. There is no cost to participate.
Possible risks include feeling tired, sweating, or experiencing temporary changes in heart rate or blood pressure. Rare but serious risks could include overheating, dehydration, or fainting. The study team will monitor you closely throughout the process to minimize risks and will stop the session immediately if there are any safety concerns.
256 studies on the registry are indexed under Hyperthermia; 73 are open to participants now.
This study's planned enrollment of 20 is below the median of 40 across 232 interventional studies indexed under Hyperthermia.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Start is estimated for Sep 2026; primary completion for Mar 2027, 6 months later.
Of 103 non-industry interventional studies with no phase under Hyperthermia, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 30. This study's planned 6 months is below that.
Counting every sponsor, half of 108 studies reached it within 18 months; a quarter within 7 and three quarters within 30.
How these figures are worked out, and which studies are left out of them.
