About this study

Official title: An Open Label Safety Study of Inhaled Gaseous Nitric Oxide (gNO) for Adults & Adolescents With Non-Tuberculous Mycobacteria, Burkholderia Spp, Aspergillus Spp and Corona-like Viral (Sub-Study) Infections

Non tuberculous mycobacteria (NTM), Burkholdria spp, Aspergillus in the lung are almost impossible to eradicate with conventional antibiotics. In addition COVID-19 has know current treatment. These patients have few options to treat their lung infection. Nitric oxide has broad bactericidal and virucidal properties. It has been shown that nitric oxide was safe to be inhaled for similar cystic fibrosis patients and reduced drug resistant bacteria in the lungs. Further, research indicates that clinical isolates of NTM, Burkholderia spp, Aspergillus spp and Corona-like viruses can be eradicated by 160ppm NO exposure in the laboratory petri dish. This is not the first time inhaled NO treatment has been used in patients with difficult lung infections. This study will provide more data to see if NO therapy can reduce the bacterial load in the lungs, help the patients breath better; and in the case of COVID-19 act as a anti-viral agent resulting in the reduction of incidence of oxygen therapy, mechanical assistance of BIPAP, CPAP, intubation and mechanical ventilation during the study period.

Main Study

Primary Objective: Assess the safety of inhaled NO (gNO) in adults \& adolescents with NTM, Burkholderia, Aspergillus Lung Infections and Viral Lung (COVID-19) Infections

Safety will be evaluated by unanticipated adverse events in clinical labs (hematology, coagulation, and serum chemistries); in vitals; in inspired concentration of NO, O2 and NO2 delivered to each subject and; in real time methemoglobin and oxygen saturation levels.

Primary Endpoint:

Determine the safety of gNO in the NTM population,

  • as confirmed by no unanticipated adverse events
  • Absence of a deleterious mean change in FEV1% predicted (absolute) from baseline

Secondary safety Endpoint: Determine the efficacy of inhaled NO in adults with NTM, Burkholderia and Aspergillus Lung Infections

Efficacy will be evaluated by measuring the change in lung function with spirometry (specifically absolute change in FEV1 % predicted) from baseline to Days 5, 12, 19 and 26.

Secondary Efficacy Endpoint Determine the presence of an efficacy signal of gNO in the NTM, Burkholderia and Aspergillus Lung Infections

Efficacy will be assessed by the antimicrobial effect of inhaled NO on the density of NTM species and other microorganisms in sputum. Serial measurements of these microbial colony counts in sputum have been previously used as a measure of antimicrobial activity in other clinical trials of antibiotics in NTM.

  • as confirmed by an improvement in pre-treatment bacterial colonization and post-treatment bacterial colonization on Days 19 and 26 as compared to baseline.

Efficacy will be assessed by change in Quality of Life Score.

  • as assessed by an improvement in CRISS Score on Day 5, 19 and 26 as compared to baseline measurement;
  • as determined by improvement in six-minute walk test with one minute recovery as compared to baseline measurement.

COVID-19 Substudy

Primary Endpoint:

Efficacy will be evaluated by measuring reduction in the incidence of mechanical assistance of BIPAP, CPAP, intubation and mechanical ventilation during the study period.

Secondary Endpoints:

  1. Proportion of patients with mild COVID2019 who deteriorate to a severe form of the disease requiring mechanical intervention like BIPAP/CPAP, intubation and mechanical ventilation;
  2. Mortality from all causes during the study period;
  3. Negative conversion of COVID-19 RT-PCR from upper respiratory tract measured as the proportion of patients with a negative conversion of RT-PCR from an oropharyngeal or a nasopahryngeal swab;
  4. Time to clinical recovery defined as the time from initiation of the study to discharge or to normalization of fever (defined as <36.6°C from axillary site, or < 37.2°C from oral site or < 37.8°C from rectal or tympanic site), respiratory rate (< 24 bpm while breathing room air);
  5. Alleviation of symptoms recorded in the Modified Jackson Cols score with particular definition of cough (defined as mild or absent in a patient reported scale of severity).

What is being measured

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

  1. Measure the safety of 160ppm inhaled nitric oxide delivery in NTM subjects

    Measure the number of unanticipated adverse events over the duration of the study protocol

    Measured: 26 Days

Secondary outcomes (3)
  1. Measure the effect of 160ppm inhaled nitric oxide delivery on lung spirometry in NTM subjects

    Measure the change in absolute FEV1.0 change from baseline during 160 ppm inhalation therapy

    Measured: Day 5,12,19 and 26

  2. Measure the antimicrobial effect of 160ppm inhaled nitric oxide on lung NTM bacterial load in the sputum

    Measure the difference from baseline NTM species bacterial load (0 to +4) in sputum during 160ppm nitric oxide inhalation therapy

    Measured: Day 19 and 26

  3. Measure the effect of 160ppm inhaled nitric oxide on Quality of Life (CRISS) Score

    Measure the difference from baseline CRISS (0-100) during 160ppm nitric oxide inhalation therapy (lower score represents higher quality of life)

    Measured: Day 19 and 26

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 11 inclusion and 25 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: stopped early, as of the sponsor's last update on 16 Jul 2021. 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.

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?

The study was stopped early (reason given: Covid Incidence too low and Funding Completed). Results are not available in the source record.

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?

Measure the safety of 160ppm inhaled nitric oxide delivery in NTM subjects (time frame: 26 Days). 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 NCT03331445, 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 16 Jul 2021.
