About this study
Official title: A Pilot Study of the Physiologic Effects of Using the Breathe Technologies Noninvasive Open Ventilation System During Constant Work Rate Exercise in Subjects With Chronic Obstructive Pulmonary Disease
Pilot study in 15 stable male subjects with severe-to-very severe Chronic Obstructive Pulmonary Disease (COPD) to evaluate the effects of short term use of the Breathe Technologies noninvasive open ventilation (NIOV) system on respiratory mechanics during constant work rate exercise in subjects with severe COPD.
Read the detailed description
Study was a randomized double-blinded crossover design in which subjects completed a series of exercises at a constant work rate while using 1) Test noninvasive ventilation (NIOV) system powered by compressed air, 2) Test NIOV system powered by 100% oxygen, 3) nasal cannula oxygen, 4) nothing (Control). Subjects were assessed during constant work rate exercise as reflected by exercise duration, isotime oxygenation (SpO2), and isotime dyspnea score (Borg). Exercise sessions took place over 4 visits with each visit lasting approximately 5 hours.

| Study group | Role | What they receive |
|---|---|---|
| NIOV - Room air | Experimental | Subjects exercise using the NIOV device powered by compressed air (room air, 21% O2). Receives: Device: NIOV - Room Air |
| NIOV - Oxygen | Experimental | Subjects exercise using the NIOV device powered by compressed medical oxygen (100% O2). Receives: Device: NIOV - Oxygen |
| Nasal Cannula Oxygen | Active comparator | Subjects exercise using a standard nasal cannula using medical oxygen (100% O2). Receives: Device: Nasal Cannula Oxygen |

What is being measured
The primary outcome is the main question the study is designed to answer.
Exercise Duration for Constant Work Rate Exercise Tests Under 4 Test Conditions
Mean differences between NIOV - oxygen, NIOV - Room Air, Nasal Cannula Oxygen, and no treatment (control).
Measured: Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxygen and Nasal Cannula Oxygen.
Secondary outcomes (2)
SpO2 During Constant Workrate Exercise at Isotime
Mean differences between NIOV - oxygen, NIOV - Room Air, Nasal Cannula Oxygen, and no treatment (control).
Measured: Outcome was measured in each of the Study day 1,2, 3 and 4. Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxyg
Borg Dyspnea Score During Constant Workrate Exercise at Isotime
Mean differences between NIOV - oxygen, NIOV - Room Air, Nasal Cannula Oxygen, and no treatment (control) at isotime. Borg Dyspnea Score ranges in values from 0 to 10. The lower score represent better outcome.
0 = No breathlessness at all, representing better outcome 10 = Maximum breathlessness, representing worse outcome
Measured: Outcome was measured in each Study day 1,2,3 and 4. Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxygen and N

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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Oct 2016). 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?
Exercise Duration for Constant Work Rate Exercise Tests Under 4 Test Conditions (time frame: Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxygen and Nasal Cannula Oxygen.). 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 12 Oct 2016; AzTrials last refreshed its copy on 6 Nov 2026.
