About this study
Official title: Prospective, Randomized, Placebo Controlled Trial of the Efficacy and Safety of Inhaled Nitric Oxide (NO) in Cystic Fibrosis (CF) Patients
Prospective, randomized, placebo controlled, phase II clinical study of subjects crossing over from an approved inhaled antibiotic to inhaled nitric oxide as compared to a placebo control arm.
Read the detailed description
This is a multi-center, randomized, placebo controlled, phase II clinical study comparing an investigational drug to a placebo control. Screening data will be reviewed to determine subject eligibility. All subjects including screen failure subjects will be recorded on screening logs at their respective sites. Upon successful completion of all screening procedures, a subject will be considered eligible for enrollment. The subject will be enrolled and randomized in as close a time proximity to the first treatment application as is possible in order to minimize the possibility of dropout while enrolled but before undergoing treatment. With a 1:1 investigational treatment to placebo control, subjects will be randomized to one of the two arms. Subjects in the investigational treatment arm will be administered doses of NO (0.5% NO in 99.5% nitrogen) diluted in room air by inhalation four times daily (30-minute inhalations at least 3 hours apart) for 7.5 days on Days 1, 2, 3, 4, 5, 8, 9, and 10 (three treatments on Days 1 and 10). Subjects in the placebo arm will breathe 100% nitrogen diluted in room air in the same proportion as the investigational arm. Subjects will remain in the clinic for 30 minutes after completing the last treatment of each day. All subjects will be asked to return to the clinic for additional evaluations on Days 15 and 36.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in FEV1 % predicted from baseline to Day 15
The primary efficacy variable for this study is absolute change from baseline FEV1% predicted to Day 15. For each subject, the change will be calculated as the FEV1% value minus the baseline FEV1%, i.e., a positive change in FEV1% values will indicate an increase in FEV1% after treatment. The primary endpoint for this trial is the comparison of the mean absolute change from baseline in FEV1% between treatment groups.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Nitric Oxide 160 ppm in people with Cystic Fibrosis, run by Novoteris, LLC at 7 sites in 2 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 16 inclusion and 33 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 5 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States, 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. Some participants in this study may receive a placebo. 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: Terminated for the safety of cystic fibrosis clinical trial subjects due to Covid-19.). 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?
Change in FEV1 % predicted from baseline to Day 15 (time frame: 15 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 5 Mar 2021; AzTrials last refreshed its copy on 8 Nov 2026.
