Optimizing Fluid Status

February 27, 2014 updated by: Francisco Maduell

Clinical Investigation Plan Optimizing Fluid Status

Title of study: Optimizing Fluid Status

Study code: HD-IIT-01-E

Study design: Prospective open design in study centre at two locations

Applied medical device: Body Composition Monitor (BCM) for determination of fluid overload and dry weight

Aim of the study: To improve the fluid status in chronic HD patients (measured as OH (overhydration) or TAFO (time averaged fluid overload)) based on BCM measurements. Up to now, the BCM was occasionally applied in both locations of the study centre.

Study hypothesis: Regular measurement of fluid status (assessed by BCM) and display of dry weight (post-weight plan)will have significant consequences, namely a decrease of the:

  • time averaged fluid overload (TAFO),
  • proportion of patients with severe overhydration OH > 2.5 L,or OH/ECW > 15 %)
  • proportion of dehydrated patients (OH < -1.0 L, or OH < -7 %),
  • mean overhydration,
  • variance of overhydration,
  • time outside the reference range (-1.0L < OH < 2.5L).

Devices used in this study: Dialysis machine 5008 equipped with Blood Pressure Monitor BPM, Blood Volume Monitor BVM, Blood Temperature Monitor BTM, and Online Clearance Monitor OCM ; Body Composition Monitor BCM ; Data management software / database system NephroLink Disposables used in this study: BVM blood lines and BCM electrodes

Patients: 60 patients

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
56

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
intra-individual difference in TAFO between study start and study end
Time Frame: 3 months
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
