BVA-200 vs BVA-100 Validation Study

Status Completed

Clinical Trial Summary

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.

Clinical Trial 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 Sufficient blood will be withdrawn at each phlebotomy to permit such duplicate measurement.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"). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
