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
  • No healthy volunteers
  • Adult, Older adult
  • Adults with hypertension on hemodialysis Hypertensive, long-term (3 months or more) hemodialysis patients will be studied over a 6 hemodialysis baseline phase during which 44-hour interdialytic ambulatory BP will be performed and baseline symptoms collected. Patients with well-controlled hypertension, on anti-hypertensive therapy will have blood pressure medications withdrawn until they become hypertensive as assessed by 44-hour interdialytic ambulatory blood pressure recording. We will exclude patients who have had vascular event (stroke, myocardial infarction or limb ischemia requiring bypass) within previous six months, ambulatory BP >170 mm Hg systolic or >100 mm Hg diastolic, those who miss 2 or more hemodialysis treatments in the previous month, abuse street-drugs, require home oxygen, have symptomatic congestive heart failure or are morbidly obese (body mass index > 40 kg/m2).

What participants receive

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

  • UltrafiltrationOther

    All patients participating in the trial require evaluation of dry-weight at each dialysis visit for evaluation. An initial weight loss of 0.1kg/10 kg body-weight will be prescribed per dialysis. If ultrafiltration is not tolerated based on muscle cramps, need for excessive saline or symptomatic hypotension, the intensity of ultrafiltration will be reduced by 50%. If ultrafiltration is still not tolerated, the weight loss will be further reduced by 50%. If the patient cannot tolerate at least 0.2 kg incremental weight loss per dialysis, the patient will be said to be at goal dry-weight. Thus, by this protocol, all patients must experience symptoms of volume depletion to be at dry weight.

What is being measured

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

  1. The primary outcome parameter will be systolic reduction in 44h-interdialytic ambulatory BP with ultrafiltration as compared to the control group by intention to treat analysis

    Measured: 0, 4, 8 wks

Secondary outcomes (1)
  1. Per protocol analysis of primary outcome with 1. weight loss as the covariate. 2. baseline left-atrial size and weight loss as covariates.3. Others: (Description restricted by space limitation)

    Measured: 0, 4, 8 wks

Questions about this trial

What is this clinical trial studying?

A study testing Ultrafiltration in people with Hypertension and Left Ventricular Hypertrophy, run by Indiana University 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?

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 28 Mar 2011. 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?

The primary outcome parameter will be systolic reduction in 44h-interdialytic ambulatory BP with ultrafiltration as compared to the control group by intention to treat analysis (time frame: 0, 4, 8 wks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00067665, which also lists 6 linked publications.

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 28 Mar 2011.
