ClinicalTrials.gov Identifier: NCT00060840
  Purpose

The purpose of this study is to assess the utility of nitric oxide for inhalation during left ventricular assist device (LVAD) implantation following cardiopulmonary bypass (CPB). This is to be assessed by the number of patients in each treatment group meeting failure criteria within 24 hours on study drug, as defined by two or more of the following:

  • Left ventricular flow rate index (LVFRI) ≤ 2.0 L/min/m2
  • Administration of ≥ 20 inotropic equivalents (IE)

    • 10 µg/kg/min dopamine, dobutamine, enoximone or amrinone is equivalent to 10 IE
    • 0.1 µg/kg/min epinephrine or norepinephrine is equivalent to 10 IE
    • 1 µg/kg/min milrinone is equivalent to 15 IE
    • 0.1 U/min vasopressin is equivalent to 10 IE
  • Mean arterial pressure (MAP) ≤ 55 mmHg
  • Central venous pressure (CVP) ≥ 16 mmHg
  • Percent mixed venous oxygen saturation (SvO2) ≤ 55%

Or at least one of the following criteria:

  • Failure to wean from cardiopulmonary bypass at least once due to hemodynamic failure. Re-initiation of cardiopulmonary bypass to correct bleeding or other technical issues will not be considere 'failure to wean'
  • Death

Primary Outcome Measures:
  • The primary objective of the trial is to assess the utility of nitric oxide for inhalation for the management of acute right ventricular failure during LVAD placement. [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]

Enrollment: 150
Study Start Date: July 2003
Study Completion Date: July 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
A: Active Comparator
Stratified based on the LVAD they receive (axial or pulsatile)
Drug: Nitric Oxide
40ppm of drug will be continuously administered at least 5 minutes prior to initiating the first weaning attempt from CPB
P: Placebo Comparator
Stratified based on the LVAD they receive (axial or pulsatile)
Drug: placebo
Open label investigational drug may be administered once a patient meets a minimum of two failure criteria or fails to wean at least once due to hemodynamic failure from cardiopulmonary bypass.

Detailed Description:

40 ppm of either nitric oxide for inhalation or N2 (placebo)will be continuously administered to the patient starting at least 5 minutes prior to initiating the first weaning attempt from CPB and continue until the patient is either extubated, has reached failure criteria, or has been treated with study drug for 48 hours following discontinuation of CPB, whichever come first.

All patients will be monitored peri-operatively with a pulmonary arterial line, central venous line, and systemic arterial line. Baseline data collection by a designated clinical staff member will begin following induction of anesthesia and prior to skin incision. Following a successful wean from cardiopulmonary bypass, post-op data will be collected within 1 hour following end time of surgery. Data will then be collected at 6, 12, 18, 24, and 48 hours from post-op or until extubation, in which case weaning from study drug will begin.

Open label investigational nitric oxide for inhalation may be administered once a patient meets a minimum of two of the failure criteria or fails to wean at least once due to hemodynamic failure from cardiopulmonary bypass.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • Scheduled to undergo their first LVAD implantation, (or at least 6 months after explanation of a previous LVAD).
  • Has a pulmonary vascular resistance of at least 2.5 Wood units (200 dynes/sec.) in the 30 days prior to LVAD placement.
  • Greater than 18 years of age.
  • Signed IRB approved informed consent.

Exclusion criteria:

  • Patients with congestive heart failure due to giant cell myocarditis or restrictive cardiomyopathy.
  • Elective Biventricular Assist Device (BiVAD) surgery, or current support with a temporary BiVad.
  • LVAD procedure expected to be done without cardiopulmonary bypass.
  • Pregnancy (a negative pregnancy test must be documented prior to enrollment).
  • Received nitric oxide by inhalation therapy within the past 24 hours.
  • Investigational drugs that are expected to change systemic or pulmonary vascular resistance are not allowed.
