About this study

Official title: Evaluation of the Clinical Performance of the Quantra System With the Quantra Surgical Cartridge in Adult Patients Undergoing Major Surgical Procedures

This study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the Quantra Surgical Cartridge in patients undergoing major surgical procedures specifically, major cardiac and vascular procedures and major orthopedic surgery (primarily complex spine surgeries).

Read the detailed description

The Quantra System is a fully integrated and automated in vitro diagnostic device which uses SEER Sonorheometry, an ultrasound-based technology, to characterize the viscoelastic properties of a whole blood sample during coagulation. The Quantra Surgical Cartridge was developed to monitor hemostasis during major surgical procedures in adult patients. The cartridge consists of four independent channels each containing different sets of reagents, which provide four measurements performed in parallel yielding six parameters that depict the functional status of a patient's coagulation system.

This multi-center, prospective, observational study will evaluate the performance of the Quantra System as compared to standard coagulation tests and comparable measures determined using the ROTEM Delta.

What is being measured

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

  1. Comparison of Quantra Clot Time and Clot Stiffness results to standard coagulation test results

    Coagulation function assessed by Quantra and standard coagulation tests

    Measured: Baseline, during surgery, and up to 24 hours post-surgery

  2. Comparison of Quantra Clot Time and Clot Stiffness results to comparable ROTEM Delta results

    Coagulation function assessed by Quantra and ROTEM Delta

    Measured: Baseline, during surgery, and up to 24 hours post-surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Blood Loss, Surgical, run by HemoSonics LLC at 4 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 6 inclusion and 6 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 31 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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. 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?

Comparison of Quantra Clot Time and Clot Stiffness results to standard coagulation test results (time frame: Baseline, during surgery, and up to 24 hours post-surgery). 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?
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 31 Jul 2018.
