Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The population to be studied consists of subjects who require parenteral anticoagulant therapy with UFH in accordance with the approved label indications for heparin administration. • Therapeutic Group (T): Patients pre-heparin Patients undergoing procedure requiring anticoagulation with UFH

Who may be able to join

  • Therapeutic Group
  • Patients meeting all of the following criteria will be considered for entry into the study:
  • Males and females 18 years or older.
  • Patients scheduled for elective or urgent procedures requiring anticoagulation with UFH.
  • Patients requiring heparin anticoagulant therapy for any approved indication and being managed and monitored with the ACT test.

Who cannot join

  • The following criteria define the population of subjects who will not be accepted in the study:
  • The subject develops a significant, unexpected, concurrent illness or adverse event before the first whole blood sample is drawn.
  • The subject with a hematocrit of less than 20% or greater than 55% since these samples are not recommended for testing due to optical densities outside of the Hemochron instrument levels of detection.

About this study

This study is designed to evaluate and verify the clinical accuracy of the Hemochron® MCS 7000 Whole Blood Microcoagulation System; a point-of-care, whole blood Activated Clotting Time (ACT) measurement in comparison with the Hemochron Signature Elite® Whole Blood Microcoagulation System; a 510(k) cleared predicate device. This is a multi-center, prospective method comparison, with data to be analyzed separately from each site as well as combined for all sites.

Read the detailed description

The study will be performed in the clinical setting by trained professional operators.

Group 1: Whole Blood Coagulation Test 1, GEM Hemochron® 100

Group 2: Whole Blood Coagulation Test 2, Hemochron® Signature Elite® 7000 Whole Blood Microcoagulation System

Ex-vivo whole blood samples destined for discard after all medically directed tests are complete will be used from heparinized patients undergoing standard of care interventional procedures in different clinical settings. These include, but are not limited to, the cardiovascular operating room (CVOR), cardiac catheterization lab, surgical intensive care unit (SICU), the electrophysiology (EP) lab, and in extracorporeal membrane oxygenation (ECMO) applications.

A distribution of ACT values is necessary to evaluate clinical accuracy. The target number of subjects for each site is 100.

Samples will be examined at baseline (pre-heparin administration) and at the end of the procedure. Heparinized samples may be obtained for ACT testing once or multiple times while heparin is administered throughout the duration of the procedure. The frequency and time intervals of ACT testing will be determined by the Standard of Care. No additional blood volume or extra blood draws will occur as the result of this study.

The work flow for the testing process will be consistent across all sites. Expected duration of the study is dependent upon the site logistics but generally is expected to last no more than four to six weeks.

ACT results generated from the GEM Hemochron 100 instrument during this study will be used solely for research purposes and will not be used for anticoagulation management of study subjects. No patient follow up is required.

The study will include two GEM Hemochron 100 instruments, trained operators, and two Signature Elite instruments for each procedure.

Guidance was obtained from Point-of-Care Monitoring of Anticoagulation Therapy; Approved Guideline (CLSI POCT14-A), CLSI EP09-A3: "Method Procedure Comparison and Bias Estimation Using Patient Samples; Approved guideline Third Edition" and peer reviewed literature.

All study data will be collected on Case Report Forms and all analysis will be performed by Accriva.

Study groupRoleWhat they receive
Blood coagulation test 1Therapeutic: Waste blood from heparinized patients undergoing interventional procedures (standard of care) in different clinical settings will be used to conduct coagulation tests using GEM Hemochron 100 during the course of the procedure before ("baseline") and after heparin administration. There is no drug administration or therapeutic intervention in this study. The interventional procedure (described above) is standard of care and all results of blood coagulation testing using GEM Hemochron 100 performed in this study are not used to influence that care.
Receives: Diagnostic Test: GEM Hemochron 100 ACT
Blood coagulation test 2Therapeutic: Waste blood from heparinized patients undergoing interventional procedures (standard of care) in different clinical settings will be used to conduct duplicate coagulation tests using Signature Elite during the course of the procedure before ("baseline") and after heparin administration. There is no drug administration or therapeutic intervention conducted in the course of this study. The interventional procedure (described above) is standard of care. The only difference in standard of care is that the blood coagulation test is run in duplicate.

What is being measured

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

  1. Hemochron® MCS 7000 Whole Blood Microcoagulation System ACT measurements (time of whole blood coagulation in seconds) are clinically equivalent to those of the Hemochron Signature Elite® Whole Blood Microcoagulation System

    Demonstrate that the Hemochron® MCS 7000 Whole Blood Microcoagulation System Activated Clotting Time (ACT) measurements (time of whole blood coagulation in seconds) are clinically equivalent to those of the Hemochron Signature Elite® Whole Blood Microcoagulation System; a 510(k) cleared predicate device

    Measured: Therapeutic: 1 day; Normal: 1 day (duration of a single venous blood collection)

Questions about this trial

What is this clinical trial studying?

An observational study of Blood Coagulation Test, run by Accriva Diagnostics at 9 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 5 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 26 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 9 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?

Results are not available in the source record.

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?

Hemochron® MCS 7000 Whole Blood Microcoagulation System ACT measurements (time of whole blood coagulation in seconds) are clinically equivalent to those of the Hemochron Signature Elite® Whole Blood Microcoagulation System (time frame: Therapeutic: 1 day; Normal: 1 day (duration of a single venous blood collection)). 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 26 Jul 2018.
