Trial summary
There is a lack of effective treatments for chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension. Previous studies have found that inhaled nitric oxide (iNO) can reduce pulmonary artery pressure and improve exercise capacity in COPD with pulmonary hypertension patients. Read more about this study

About this study
Official title: Study on the Mechanism of Inhaled Nitric Oxide in the Treatment of Patients With Chronic Obstructive Pulmonary Disease (COPD) Complicated With Pulmonary Hypertension
There is a lack of effective treatments for chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension. Previous studies have found that inhaled nitric oxide (iNO) can reduce pulmonary artery pressure and improve exercise capacity in COPD with pulmonary hypertension patients. However, the specific mechanism is unclear. The study aims to evaluate pulmonary ventilation/perfusion, pulmonary artery pressure, oxygenation, symptoms and quality of life in COPD with pulmonary hypertension patients after short-term treatment with iNO. Observing a series of pathophysiological changes caused by the treatment of pulmonary hypertension with iNO in COPD, the investigators hope to provide new theoretical basis and research ideas.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nitric Oxide Generation and Delivery SystemDevice
The Nitric Oxide Generation and Delivery System is used to deliver nitric oxide for inhalation therapy into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 15 May 2023. 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 China. 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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ruoxi He (+8618874167666, heruoxi1985@yeah.net), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ventilation-perfusion ratio (time frame: Baseline, Minutes 30). The study lists 3 primary outcomes in all. 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 15 May 2023.
