About this study

Official title: Nitric Oxide in Right Ventricular Dysfunction: Improvements in Clinical and Hemodynamic Parameters on Venoarterial Extracorporeal Membrane Oxygenation (VA-ECMO; NOVICE)

This pilot study is designed to investigate the effect of inhaled nitric oxide on cardiac, pulmonary artery, and systemic hemodynamics at various time points during venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Patients who have been initiated on VA-ECMO will be invited to participate. Inhaled nitric oxide (iNO) will be used early after VA-ECMO cannulation (once consent is obtained). After baseline hemodynamic, biochemical, and echocardiographic parameters are assessed, iNO will be initiated and all parameters will be reassessed after 30 minutes and 6 hours. Inhaled nitric oxide will then be discontinued and all parameters repeated. At the time of VA-ECMO weaning (timing determined by clinical team), iNO will be reinitiated with repeat assessment of hemodynamic, biochemical, and echocardiographic parameters both prior to the wean and after the wean (whether successful or not).

Read the detailed description

This is a proof of concept, pilot, phase II study using iNO in patients on VA-ECMO. Stage 1 will assess the participant's response to iNO early after cannulation. Stage 2 will assess the participant's response to iNO during the ECMO weaning process.

Stage 1 Patients in whom VA-ECMO is being initiated will be invited to participate. Hemodynamic, echocardiographic, and biochemical parameters will be measured immediately prior to iNO administration and repeated 30 minutes after iNO initiation. iNO will be continued for six hours to allow hemodynamic and oxygenation parameters to stabilize as per previous protocols in the literature. After six hours, hemodynamic, echocardiographic, and biochemical parameters will be re-assessed after which iNO will be discontinued. All parameters will be re-evaluated 30 minutes after iNO discontinuation.

Stage 2 A weaning trial will be performed at 1) the earliest signs of myocardial recovery or b) day 5. Myocardial recovery will be defined as: mean arterial pressure > 60 millimeters of mercury (mmHg) on no or minimal inotropic/vasopressor support, arterial pulse pressure > 10 mmHg, and minimal respiratory support (oxygen saturation > 88% on < 2 liters by nasal cannulae, or minimal ventilator setting if intubated). Inhaled nitric oxide will be re-initiated 30 minutes prior to the ECMO weaning trial. Adequacy of perfusion will be defined as a mixed venous oxygen saturation of > 70%. Hemodynamic, echocardiographic, and biochemical parameter will be recorded immediately prior to iNO administration and then at 30 minutes prior to the ECMO weaning trial. ECMO will be weaned as per the standard protocol at the University Health Network with re-assessment of all parameters after weaning is complete. When ECMO weaning is unsuccessful, these parameters will be recorded immediately prior to re-initiation of full flow VA-ECMO and 30 minutes thereafter. VA-ECMO weaning will be re-attempted at 24-48 hours at the discretion of the medical team.

What participants receive

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

  • Inhaled nitric oxideDrug

    Stage 1: Patients in whom VA ECMO is being initiated will be invited to participate. Hemodynamic, echocardiographic, and biochemical parameters will be measured immediately prior to iNO administration, and thirty minutes after initiation. After six hours, hemodynamic, echocardiographic, and biochemical parameters will be re-assessed after which iNO will be weaned. All parameters will be re-evaluated 30 minutes after iNO discontinuation.

    Stage 2: iNO will be re-initiated 30 minutes prior to the ECMO weaning trial. Hemodynamic, echocardiographic, and biochemical parameter will be recorded immediately prior to iNO administration and then at 30 minutes prior to the ECMO weaning trial. When ECMO weaning is unsuccessful, these parameters will be recorded immediately prior to re-initiation of full flow VA ECMO and 30 minutes thereafter. If successful, data will be collected after the wean and after iNO discontinuation.

What is being measured

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

  1. Participant recruitment

    Recruitment of ten participants

    Measured: February 2020

  2. Right Heart - Qualitative function, change from baseline

    Mild/moderate/severe dysfunction as determined by reading echocardiographer

    Measured: After 6 hours of inhaled nitric oxide

  3. Right Heart - Tricuspid annular plane systolic excursion (TAPSE), change from baseline

    Measured in milimeters

    Measured: After 6 hours of inhaled nitric oxide

  4. Right Heart - RV fractional area change, change from baseline

    Measured in percent

    Measured: After 6 hours of inhaled nitric oxide

  5. Right Heart - longitudinal myocardial velocity (S'), change from baseline

    Measured in meters per second

    Measured: After 6 hours of inhaled nitric oxide

Secondary outcomes (3)
  1. Left Heart Function

    Left ventricular ejection fraction

    Measured: After 6 hours of inhaled nitric oxide

  2. Weaning success

    Explore the effect of iNO on the rate of successful VA ECMO weaning.

    Measured: Within 5 days of cannulation but may be repeated at 7 days if initially unsuccessful.

  3. Long-term RV function

    Assess RV function after LVAD implantation or cardiac transplantation if these occur during the same hospitalization.

    Measured: Within three months of initial ECMO cannulation.

Questions about this trial

What is this clinical trial studying?

An observational study of Extracorporeal Membrane Oxygenation and Nitric Oxide, run by Filio Billia at 1 site in Canada.

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 7 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 4 Nov 2020. 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 Canada. 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?

Results are not available in the source record.

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

Contact Andrea L Daly, MD (16475457454, andrealdaly@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Participant recruitment (time frame: February 2020). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Nov 2020.
