Comparison Study of Daily Ultrafiltration and Twice-weekly Hemodialysis

April 28, 2014 updated by: Renal Research Institute

Pilot Trial To Study Blood Pressure, Weight and Hydration State in Patients Undergoing A Treatment Regimen of Daily Ultrafiltration and Twice-weekly Hemodialysis As Compared to Conventional Three Times Per Week Hemodialysis

In this study, the researchers want to find out how patients who have ultrafiltration (removal of excess fluid) 6 times a week and twice-weekly dialysis (removal of excess fluid and waste products) do in terms of their blood pressure and weight. The researchers believe that maintaining patients at their estimated target weight throughout the week using daily ultrafiltration will reduce their blood pressure to levels shown in other similar studies. Such a reduction in blood pressure may reduce the incidence of cerebral vascular disease, peripheral vascular disease, coronary artery disease, and congestive heart failure. The researchers also believe that patients' quality of life will improve while they are undergoing daily ultrafiltration.

Studies show that more frequent dialysis treatments result in fewer symptoms for patients. The patients feel better and avoid the weight gains and symptoms that patients have on three times a week dialysis. In addition, their blood lab results are better controlled, requiring less medication.

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.

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
