About this study

Official title: Effects of iNO on Invasively Derived Pulmonary Vascular Parameters in Patients With Pulmonary Arterial Hypertension

Pulmonary hypertension is characterized by an increase in the pressures in the blood supply to the lungs greater than a mean pressure of 25mmHg and a concomitant increase in overall pulmonary vascular resistance (PVR). In patients who have remodeling of their pulmonary vasculature, PVR will increase with exercise instead of decreasing as it would in normal patients. Based on published evidence, the investigators intend to investigate the effects of inhaled nitric oxide (iNO) on patients undergoing standard exercise techniques who have separately and previously had an implanted pulmonary artery monitoring device (CardioMems by St Jude Medical, Inc.) placed.

What is being measured

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

  1. Difference in Ambulatory 6 Minute Walk Distance (6MWD) Pulmonary Artery (PA) Pressures (Systolic, Diastolic, Mean) Between the Post-intervention (iNO+) and Pre-intervention (iNO-) Condition as Measured by the CardioMems Device

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

Secondary outcomes (11)
  1. Change in CardioMems Cardiac Output

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

  2. Change in 6 Minute Walk Distance (6MWD)

    Difference (in distance walked between 2 set points over 6 minutes) at baseline (t=0) to post-intervention (t=2h).

    Measured: 2 hours

  3. Change in O2 Saturations

    Measured: 2 hours

  4. Change in Modified Borg Dyspnea Scale

    The Modified Borg Dyspnea scale measures patient's subjective analysis of dyspnea from 0 ("nothing at all") to 10 ("maximal") during the 6MWD test with the highest value recorded and difference calculated between baseline (t=0) and post-intervention (t=2h).

    Measured: 2 hours

  5. Change in O2 Requirements

    Number of patients that required more or less oxygen by nasal prongs during the course of the study.

    Measured: 2 hours

  6. Change in Mean Arterial Pressure

    Difference between baseline (t=0) and post-intervention (t=2h).

    Measured: 2 hours

  7. Change in Heart Rate

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

  8. Change in Rate Pressure Product

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

  9. Change in Right Ventricular (RV) Power

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

  10. Change in Stroke Volume

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

  11. Change in RV Stroke Work Index

    Difference between baseline (t=0) and post-intervention (t=2h)

    Measured: 2 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Nitric Oxide in people with Pulmonary Arterial Hypertension, run by Allegheny Singer Research Institute (also known as Allegheny Health Network Research Institute) at 1 site in United States.

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 4 inclusion and 1 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: finished, as of the sponsor's last update on 24 Sep 2018. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Sep 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference in Ambulatory 6 Minute Walk Distance (6MWD) Pulmonary Artery (PA) Pressures (Systolic, Diastolic, Mean) Between the Post-intervention (iNO+) and Pre-intervention (iNO-) Condition as Measured by the CardioMems Device (time frame: 2 hours). 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 NCT02734953, which also lists 3 linked publications.

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 24 Sep 2018.
