About this study

The purpose of this study is to compare the feasibility, safety and efficacy of hemodialysis with unfractionated heparin compared to hemodialysis with Citrasate in Critically Ill Patients.

Read the detailed description

Objective : To compare the feasibility, safety and efficacy of Sustained Low Efficiency Daily Hemodialysis (SLEDD) using regional anticoagulation with Citrasate® compared to systemic anticoagulation with unfractionated heparin in critically ill patients.

Design : Prospective, randomized, single-center clinical trial Setting : mixed medical-surgical 45 bed ICU in a tertiary university hospital Patients : 250 patients with Acute Kidney Injury (AKI) stage III needing renal replacement therapy Interventions : Patients are randomized to receive SLEDD using standard dialysate and systemic anticoagulation with UF versus SLEDD using Citrasate®-dialysate with no additional UF.

Measurements and main results :

Primary end point :

  • The incidence of premature interruptions of the dialysis procedure attributed to hemofilter clotting.

Secondary end points :

  • The incidence of bleeding episodes as defined by the WHO-criteria
  • The transfusion requirements
  • The incidence of technique failure
  • The incidence of metabolic derangements (metabolic alkalosis, metabolic acidosis, hypocalcemia, hypercalcemia, hypernatremia, hyponatremia)
  • The incidence of citrate intoxication
  • The dialysis efficiency expressed as Kt/V and URR

Tertiary end points :

  • All cause mortality at day 28 and day 90 after inclusion

What participants receive

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

  • Unfractionated heparinDrug

    Also called Unfractionated Heparin, LEO laboratories Ltd, MA #PL 0043/0041R

    dose 5-10 IU/kg/hrs adaptations of infusion rate upon APTT measurements during hemodialysis

  • CitrasateDrug

    Also called Citrasate, Advanced Renal Technologies, MA #K000792

    Citrasate is infused as a dialysate

Study groups in NCT01228292
Study groupRoleWhat they receive
Standard AnticoagulationActive comparatorHemodialysis is performed using standard anticoagulation using unfractionated heparin if no contra-indications for the use of heparin exist. If contra-indications for heparin exist a heparin coated hemofilter (Evodial) will be used. The use of unfractionated heparin or no heparin (with coated hemofilter) is a decision to be taken before every hemodialysis.
Receives: Drug: Unfractionated heparin
CitrasateExperimentalHemodialysis is performed with Citrasate
Receives: Drug: Citrasate

What is being measured

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

  1. The incidence of premature interruptions of the dialysis procedure attributed to hemofilter clotting.

    Measured: 6 hours after starting dialysis

Secondary outcomes (5)
  1. The incidence of technique failure defined as the number of patients who develop a contra-indication for the allocated anticoagulation regimen during the study period

    Measured: during whole wtudy

  2. The incidence of bleeding episodes. A bleeding episode is defined according to the WHO bleeding criteria

    Measured: during the whole study period

  3. The transfusion requirements defined as the total of units blood products administrated during the ICU stay and per dialysis treatment

    Measured: during the whole study period

  4. The incidence of metabolic derangements during the study period

    • Metabolic alkalosis (defined as a pH > 7,5 and a bicarbonate > 24 mmol/l)
    • Metabolic acidosis (defined as a pH < 7,25 and a bicarbonate < 18 mmol/l)
    • Hypocalcemia (defined as an ionized calcium < 0,9 mmol/l)
    • Hypercalcemia (defined as an ionized calcium > 1,2 mol/l)
    • Hypernatremia (defined as a Na+ > 145 mmol/l)
    • Hyponatremia (defined a a Na+ < 130 mmol/l)
    • Citrate toxicity (defined as a total calcium/ionized calcium ratio > 2,5)

    Measured: during the whole study period

  5. Dialysis efficiency expressed as Kt/V and URR

    Measured: 6 hours after starting dialysis

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Unfractionated heparin and Citrasate in people with Acute Kidney Injury and Hemodialysis, run by University Hospital, Antwerp at 1 site in Belgium.

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 2 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 26 Oct 2010. 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 Belgium. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Walter Verbrugghe, MD (003238214149, walter.verbrugghe@uza.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of premature interruptions of the dialysis procedure attributed to hemofilter clotting. (time frame: 6 hours after starting dialysis). 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 NCT01228292, which also lists 1 linked publication.

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 26 Oct 2010.
