This study seeks to determine if increasing the dose of continuous renal replacement therapy (CRRT) reduces 90-day all cause mortality in Intensive Care Unit (ICU) patients with severe acute renal failure (ARF).

Condition Intervention Phase
Acute Renal Failure
Procedure: "augmented" CRRT regimen
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: Multicentre, Unblinded, Open Label, Randomised, Controlled Trial to Assess the Effect of Augmented Vs. Normal Continuous Renal Replacement Therapy (CRRT) on 90-Day All-Cause Mortality of Intensive Care Unit Patients With Severe Acute Renal Failure (ARF).

Further study details as provided by The George Institute:

Primary Outcome Measures:
  • Death from all causes at 90 days after randomisation. [ Time Frame: Within 90 days after randomisation ]

Secondary Outcome Measures:
  • Death within the in the intensive care unit. [ Time Frame: 0 to 90 days ]
  • Death within 28 days of randomisation. [ Time Frame: Within 28 days of randomisation. ]
  • Death prior to hospital discharge. [ Time Frame: 0 to 90 days ]
  • Length of ICU stay. [ Time Frame: 0 to 90 days ]
  • Length of hospital stay. [ Time Frame: 0 to 90 days ]
  • The need for and duration of other organ support (inotropic/vasopressor support and positive pressure ventilation). [ Time Frame: 0 to 90 days ]
  • CRRT-free days. [ Time Frame: 0 to 90 days ]
  • Dialysis-independent survival. [ Time Frame: 0 to 90 days ]

Arms Assigned Interventions
Experimental: Higher intensity CRRT regimen Procedure: "augmented" CRRT regimen
We randomly assigned critically ill patients with acute kidney injury to receive CRRT in the form of post-dilution continuous veno-venous hemodiafiltration (CVVHDF) at 25 ml/kg/hr (lower intensity) or 40 ml/kg/hr (higher intensity) of effluent flow.
Active Comparator: Lower intensity CRRT regimen Procedure: "augmented" CRRT regimen
We randomly assigned critically ill patients with acute kidney injury to receive CRRT in the form of post-dilution continuous veno-venous hemodiafiltration (CVVHDF) at 25 ml/kg/hr (lower intensity) or 40 ml/kg/hr (higher intensity) of effluent flow.

  Show Detailed Description


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. The treating clinician believes that the patient requires CRRT for acute renal failure.
  2. The clinician is uncertain about the balance of benefits and risks likely to be conferred by treatment with higher intensity or lower intensity CRRT.
  3. The treating clinicians anticipate treating the patient with CRRT for at least 72 hours.
  4. Informed consent has been obtained
  5. The patient fulfils ONE of the following clinical criteria for initiating CRRT:

    • Oliguria (urine output < 100ml/6hr) that has been unresponsive to fluid resuscitation measures.
    • Hyperkalemia ([K+] > 6.5 mmol/L).
    • Severe acidemia (pH < 7.2).
    • Urea > 25 mmol/liter.
    • Creatinine >300 micromol/L in the setting of ARF.
    • Clinically significant organ oedema in the setting of ARF (eg: lung).

Exclusion Criteria:

  1. Patient age is <18 years.
  2. Death is imminent (<24 hours).
  3. There is a strong likelihood that the study treatment would not be continued in accordance with the study protocol.
  4. The patient has been treated with CRRT or other dialysis previously during the same hospital admission.
  5. The patient was on maintenance dialysis prior to the current hospitalisation.
  6. The patient's body weight is <60 kg or >100kg.
  7. Any other major illness that, in the investigator's judgment, will substantially increase the risk associated with the subject's participation in this study.
