About this study

Official title: Pilot Study of an Inhaled Treatment for Bronchopulmonary Dysplasia

The primary objective of this study is to provide expanded access of S-nitrosylation therapy for the treatment of bronchopulmonary dysplasia

Read the detailed description

Open label study with 20 participants, open-label, with block dose escalation of 3 subjects/dose (0.5 mL/kg of 0.25 mM, 0.5 mM, or 1 mM). A minimum of seven days of surveillance will separate dosing blocks. An additional 11 subjects will be enrolled at the maximum 1 mM block (5x10-7 moles/kg). The primary outcomes are safety during 30 minutes of inhalation, and for 4 hours after inhalation, as measured by occurrence of adverse events related to the treatment + time period [during administration and tracked for next 7 days].

What participants receive

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

  • GSNODrug

    Intervention will be 30 minutes of inhaled GSNO agent in enrollment blocks of three subjects/dose (0.5 mL/kg of 0.25 mM, 0.5 mM, or 1 mM) to infants.

What is being measured

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

  1. Treatment Emergent Adverse Events

    Occurrence of >grade 3 adverse events related to the treatment

    Measured: 7 days

Secondary outcomes (5)
  1. S-nitrosoglutathione change

    Percent change in S-nitrosoglutathione pre/post treatment

    Measured: 30 minutes

  2. Change in oxygen saturation index

    Percent change in oxygen saturation index (O.S.I.) pre/post treatment. oxygen saturation index [O.S.I. = (FiO2) x (mean airway pressure) x 100 / (SpO2)]. High OSI scores indicate worse respiratory failure (high OSI = bad, low OSI = good).Scale range: zero - infinity

    Measured: 4 hours

  3. Change in GSNO catabolism pre/post treatment

    Percent change in GSNO catabolism pre/post treatment

    Measured: 30 minutes

  4. Intermittent hypoxemia as measured by oxygen saturation post treatment

    Incidence, duration, and nadirs of intermittent hypoxemia (SpO2 <80%) as measured by oxygen saturation parameters post treatment

    Measured: 4 hours

  5. Ventilator parameters post treatment

    Change in ventilator parameters post treatment

    Measured: 4 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSNO in people with Bronchopulmonary Dysplasia, run by University Hospitals Cleveland Medical Center 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 5 inclusion and 12 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: withdrawn, as of the sponsor's last update on 22 Aug 2025. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Treatment Emergent Adverse Events (time frame: 7 days). 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 22 Aug 2025.
