NCT02860130

Brief Summary

The purpose of this research is to determine if an investigational new drug solution called Prismocitrate 18 lengthens extracorporeal circuit life in patients treated with continuous renal replacement therapy (CRRT). Patients who receive CRRT treatment with Prismocitrate 18 as the anticoagulant will be compared to patients who receive CRRT treatment with no anticoagulation.

Outcome Measures

Primary Outcomes (1)

  • Time to Occurrence of Selected Prismaflex® System Alarms/Conditions

    The point estimate is time point (number of hours of the extracorporeal circuit life of a filter) at which (100-percentile)% filters are still surviving (i.e. number surviving divided by number at risk), based on the Kaplan-Meier method. For example, for the 25th percentile: after 33.18 hours, 75% of filters are still surviving. Given the early termination, this study was not powered to show statistically significant changes in efficacy endpoints. The Prismaflex M150 Set extracorporeal circuit life of filters were intended to be assessed over a maximum of 120 hours (Treatment Period) by duration of time for which each Prismaflex M150 Set could be used continuously over a maximum 72 hour time-period in each patient. The end of the extracorporeal circuit life was defined by the occurrence of one or both of the following Prismaflex® System alarms/conditions if the alarms could not be mitigated: (1) "Warning: Filter Clotted", and/or (2) "Advisory transmembrane pressure (TMP) Too High."

    Up to 120 hours post CRRT treatment initiation

Secondary Outcomes (24)

  • Change From Baseline in Patient Ionized Calcium (iCa) by Hour

    Baseline and up to 120 hours post CRRT treatment initiation

  • Extracorporeal Circuit Ionized Calcium by Hour

    Up to 120 hours post CRRT treatment initiation

  • Delivery of Prescribed CRRT Dose by Day

    Up to 120 hours post CRRT treatment initiation

  • Number of Investigator Site Facilities That Passed Prismocitrate 18 Training Assessment

    Prior to study use of Prismocitrate 18

  • Change From Baseline in Serum Bicarbonate by Hour

    Baseline and up to 120 hours post CRRT treatment initiation

  • +19 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient must be receiving medical care in an intensive care unit (ICU) (e.g., medical ICU, surgical ICU, cardiothoracic ICU, Trauma ICU, Mixed ICU, other).
  • Adult patients with AKI or other serious conditions who require treatment with CRRT.
  • Patients are expected to remain in the ICU and on CRRT for at least 72 hours after randomization.
  • Patients already receiving standard-of-care CRRT must be randomized within 24 hours of initiation of their standard-of-care CRRT.

You may not qualify if:

  • Patients requiring systemic anticoagulation with antithrombotic agents for reasons other than CRRT. The exception is patients receiving subcutaneous heparin for deep vein thrombosis prophylaxis according to institutional practice or patients on aspirin may be enrolled.
  • Patients in whom citrate anticoagulation is contraindicated such as patients with a known allergy to citrate or who have experienced adverse events associated with citrate products including patients with a prior history of citrate toxicity or patients with uncorrected severe hypocalcemia (whether in the context of current citrate administration or due to the underlying disease state).
  • Patients who are not candidates for CRRT.
  • Patients who are receiving extracorporeal membrane oxygenation (ECMO) therapy.
  • Patients with severe coagulopathy \[i.e., platelets \< 30,000/mm3, international normalized ratio (INR) \> 2, partial thromboplastin time (PTT) \> 50 seconds\] including severe thrombocytopenia (platelets \< 30,000/mm3), HIT (heparin induced thrombocytopenia), ITP (idiopathic thrombocytopenia purpura), and TTP (thrombotic thrombocytopenia purpura) should not be enrolled in the trial.
  • Patients with fulminant acute liver failure or acute on chronic liver failure as documented by a Child-Pugh Liver Failure Score \> 10.
  • Patients with refractory shock associated persistent, worsening with lactic acidosis (lactate \> 4 mmol/L). However, patients with improving subsequent serum lactate levels may be enrolled.
  • Patients unlikely to survive at least 72 hours.
  • Female patients who are pregnant, lactating, or planning to become pregnant during the study period.
  • Patients who are currently participating in another interventional clinical study.
  • Patients with a medical condition that may interfere with the study objectives.

Limitations and Caveats

The study was terminated as it was proven to be extremely difficult to enroll patients. The study termination decision was unrelated to safety or efficacy. Given the early termination, this study was not powered to show statistically significant changes in efficacy endpoints.
