About this study

Official title: A Double-Blind, Randomized Study of Clinical Efficacy of Hypothermic Therapy Following Concussion in Adolescent Athletes as Compared to a Sham-Controlled Population

This study is being conducted to determine the clinical safety and efficacy of Pro-2-Cool mediated head and neck cooling when applied after concussion and improved symptomatology among adolescent athletes as quantified by post-concussion symptom severity (PCSS) score.

Read the detailed description

This is a multi-center, prospective, randomized, double-blinded, dual-arm comparative study enrolling up to a total of 66 patients (approximately 33 patients in the treatment arm and 33 patients in the control arm) following sports-related, concussion.

Being tested
Pro2Cool Device, Sham Cooling Garment Device

What participants receive

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

  • Pro2Cool DeviceDevice

    The Pro2Cool Device is a non-invasive hypothermic therapy ("cold therapy") device that provides localized cooling of the head and neck. Water and isopropyl alcohol cooled to 6°C by the chiller assembly circulate through the cooling garment to create conductive heat transfer from the scalp and carotid arteries, thus achieving cooling of the brain.

  • Sham Cooling Garment DeviceDevice

    The sham cooling garment device will be placed with impaired cooling function (only to the head), with sham treatment temperature being set to 19°C (instead of the therapeutic 6°C specification). There will be no thermal nylon barrier that will be used and flow to the neck bladder will be closed.

Study groupRoleWhat they receive
Pro2Cool intervention with standard of careExperimentalThe treatment arm will receive standard of care for concussion along with 30 minutes of headneck cooling in the clinic while being monitored for side effects. The Pro2Cool® will be used to provide head and neck cooling.
Receives: Device: Pro2Cool Device
Sham Pro2Cool with standard of careSham comparatorThe control arm will receive standard of care like the treatment group, along with 30 minutes of sham Pro2Cool® placement in the clinic while being monitored for side effects. The Pro2Cool® device will not be used to provide neck cooling; a sham cooling garment device will be placed with impaired cooling function (only to the head), with sham treatment temperature being set to 19°C (instead of the therapeutic 6°C specification).

Questions about this trial

What is this clinical trial studying?

A study testing Pro2Cool Device in people with Concussion, Mild, run by TecTraum Inc. at 3 sites 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 10 inclusion and 20 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: looking for participants now, as of the sponsor's last update on 12 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact John Zak, MD, MBA (216-789-7676, jzak@tectraum.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change quantified by post-concussion symptom severity (PCSS) assessment score (time frame: Post-injury to 72-hour follow-up). 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 12 Aug 2026.
