About this study

Official title: HemoSonics-UVA Spinal Surgery Clinical Study Protocol

This study compares the results of current standard coagulation measurement devices to the Quantra System, a new device, using small amount of extra blood obtained during routine blood draws in neurosurgery patients.

Read the detailed description

HemoSonics is developing a novel POC diagnostic device, the Quantra System, to perform whole blood coagulation analysis and which is suitable for use in surgical and intensive care settings. The Quantra System employs a patented technology named sonorheometry, which was invented at the University of Virginia.

Sonorheometry uses ultrasound pulses to characterize the dynamic changes in viscoelastic properties of a blood sample during coagulation and clot lysis. The initial assay performed on the Quantra System will be the surgical assay for monitoring hemostasis during major surgical procedures in adult patients.

A clinical study will be conducted to evaluate the analytical performance as well as compared to existing coagulation monitoring technology

Questions about this trial

What is this clinical trial studying?

An observational study of Deformity of Spine, run by University of Virginia 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 3 inclusion and 8 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 11 May 2016. 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?

assay inter-instrument variability (time frame: 1 day). 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 11 May 2016.
