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 proposed study will be open to any volunteer meeting the inclusion/exclusion criteria listed below. We intend to highlight differential analysis of clinical patients from exemplary disease states (such as congestive heart failure and chronic kidney disease), as well as other population characteristics such as age, sex, race, etc.

Who may be able to join

  • Age: Over18 years;
  • Able and willing to provide informed written consent.
  • Subjects will be enrolled who have been prescribed a blood volume procedure using the BVA-100, as a result either of their ordinary diagnostic care or of their participation in another study that uses blood volume measurement. Subjects will be adults under treatment for conditions normally associated with the need for volume assessment, such as Heart Failure, or scheduled to receive BVA-100 measurement as part of another study.

Who cannot join

  • Pregnant women or nursing mothers.
  • Women of childbearing potential not using adequate birth control methods.
  • Known hypersensitivity to iodine or eggs.
  • Other clinical basis for precluding the use of radioactive materials.

About this study

The proposed study is a prospective, observational, investigator and patient blinded study comparing the results of blood volume measurement using the FDA-cleared Daxor BVA-100 device to the Daxor BVA-200 device. Data from this study may be pooled with data from studies with similar design conducted at other sites, for the purposes of an FDA medical device submission.

Read the detailed description

Measurements of human blood volume will be made via the indicator dilution method, using gamma counter readings of the concentration of I-131 in a subject's blood sample taken after radio-iodinated Human Serum Albumin (HSA) has been injected into the bloodstream via venous access. Each subject receiving an injection will have five separate blood samples taken, which will be analyzed separately. Each of the five measurements will be conducted in duplicate with the BVA-100 instrument and the BVA-200 instrument. Sufficient blood will be withdrawn at each phlebotomy to permit such duplicate measurement.

Subjects will be enrolled who have been prescribed a blood volume procedure using the BVA-100, as a result either of their ordinary diagnostic care or of their participation in another study that uses blood volume measurement. Subjects will be adults under treatment for conditions normally associated with the need for volume assessment, such as Heart Failure, or scheduled to receive BVA-100 measurement as part of another study. An effort will be made to ensure a range of ages and a balance of the sexes.

Subjects will be enrolled and consented sequentially. The University of Tennessee Medical Center site will document any patient who is not enrolled in the study sequentially and the reason why or who declines enrollment. Demographics of patients not enrolled will be collected to permit identification of any trends in non-enrollment. We do not anticipate any sequential patient not being offered the opportunity to participate in order to assure that there is no bias in selection of patients ("all-comers").

What participants receive

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

  • BVA-200Diagnostic test

    Blood samples collected for measurement with the BVA-100 will also be tested with the BVA-200. The BVA-200 uses whole blood collection cartridges which allow for a precise amount of blood to be measured without the need to first centrifuge and then pipette plasma aliquots. A small amount of whole blood from each sample will be set aside for BVA-200 use, while the remainder of the blood sample is used for BVA-100 measurement. The BVA-200 device was developed with the support of the Department of Defense through Phase I (W81XWH19C0048) and Phase II (W81XWH20C0025) SBIR contracts.

What is being measured

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

  1. Establish equivalence of BVA-200 to BVA-100

    Comparison of a sufficient number of indicator-dilution volume measurements between BVA-100 and BVA-200 devices to establish substantial equivalence.

    Measured: Approximately 6 months.

Secondary outcomes (3)
  1. Establish equivalence of BVA-200 to BVA-100 in TBV, RCV, PV and ATR

    Comparison of a sufficient number of full 5-point time-zero blood volume measurements between BVA-100 and BVA-200 devices, to establish substantial equivalence, including measurement of:

    • Total Blood Volume (TBV)
    • Red Cell Volume (RCV)
    • Plasma Volume (PV)
    • Albumin transudation rate (ATR)

    Measured: Approximately 6 months.

  2. Filling consistency validation

    Validation of filling consistency of at least 100 whole blood quantitative collection cartridges, in at least 40 sets of 5 samples from the same patient

    Measured: Approximately 6 months.

  3. Usability

    Validation of the ability of personnel who are not laboratorians to understand the test procedures and perform the measurement after receiving training materials (which may be a combination of written instructions, video instructions, and individual instruction) in the use of the instrument. Usability is evaluated through a User Validation Survey consisting of yes or no questions, as well as questions answered on a scale of 1 (strongly disagree) to 5 (strongly agree), where 5 is the most favorable outcome.

    Measured: Approximately 6 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and High Blood Pressure, run by Daxor Corporation 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 5 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 29 Jan 2024. 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?

Establish equivalence of BVA-200 to BVA-100 (time frame: Approximately 6 months.). 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 29 Jan 2024.
