What participants receive

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

  • Nitric Oxide for inhalationDrug

    Also called INOmax®

    Nitric Oxide (NO) for inhalation, given at 80ppm over 10 minutes using an INOvent® delivery system

  • OxygenDrug

    100% oxygen (O2) for inhalation, given at 80ppm over 10 minutes using an INOvent® delivery system

  • Nitric Oxide plus OxygenDrug

    Also called Inhaled Nitric Oxide, Oxygen

    Nitric Oxide (NO) for inhalation plus oxygen, given at 80ppm over 10 minutes using an INOvent® delivery system

What is being measured

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

  1. Number of Participants With Reversible Pulmonary Hypertension (Vasoreactivity)

    A composite of hemodynamic measurements were used to identify reversible pulmonary hypertension (vasoreactivity)

    Measured: on Day 1

Secondary outcomes (4)
  1. Number of Participants With Related Surgical Procedures Within 1 Year

    Number of participants who received surgery for pulmonary or cardiac disease within 1 year after treatment.

    Measured: within 1 year

  2. Number of Participants With Adverse Events (AEs)

    An AE was defined as any untoward medical occurrence. An AE need not have a causal relationship with treatment and included any event that was not seen at baseline or, if present at baseline, increased in severity.

    Measured: on Day 1

  3. Number of Participants With Serious Adverse Events (SAEs)

    SAEs were collected during the 12 hours after discontinuation of gas or discharge (whichever came first). An SAE was defined as any event that resulted in death, was life threatening, resulted in permanent disability or incapacity, required or prolonged inpatient hospitalization, or was a congenital anomaly. Important medical events that, without medical or surgical intervention, would also have resulted in one of the outcomes listed above were also considered as SAEs.

    Measured: within 12 hours

  4. Number of Participants With Related Surgical Procedures Within 3 Years

    Number of participants who received surgery related to pulmonary or cardiac disease within 3 years

    Measured: within 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Nitric Oxide for inhalation, Oxygen and Nitric Oxide plus Oxygen in people with Idiopathic Pulmonary Arterial Hypertension and Cardiomyopathy, run by Mallinckrodt at 18 sites in 5 countries.

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 10 inclusion and 5 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 20 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States, Spain, France, United Kingdom, Netherlands. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 16 Sep 2010). 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?

Number of Participants With Reversible Pulmonary Hypertension (Vasoreactivity) (time frame: on Day 1). 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 NCT00626028, which also lists 1 linked publication.

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 20 Dec 2019.
