About this study

Official title: Portable Oxygen Concentrator (POC) Versus Standard of Care in Patients With Long-COVID Cognitive Impairment: a Randomized Crossover Exploratory Pilot Study.

A prospective, open label, randomized, crossover, pilot, exploratory study to describe the effect of the Inogen One® G4 POC on brain hypoxia, peripheral oxygen saturation and cognitive function in adults with longterm- COVID.

Read the detailed description

After a 2-week screening/baseline evaluation, participants will be randomized in a 1:1 allocation ratio to one of the following 2 sequences: 1) portable oxygen concentrator (POC) for a first 2-week period followed by standard of care (SOC) for a second 2-week period or 2) SOC for a first 2-week period followed by POC for a second 2-week period. There will be a washout period of one week between the two treatment periods. A total of 10 subjects will be enrolled per sequence.

What participants receive

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

  • Inogen One® G4Device

    Inogen One® G4 will be used for a minimum of 3h per day at Setting 3 during the intervention period.

Study groupRoleWhat they receive
Standard of Care (SOC)No interventionSOC is defined as the patient symptoms or complications based treatment.
Portable Oxygen ConcentratorExperimentalInogen One® G4 Portable Oxygen Concentrator (POC) is used on a prescriptive basis by subjects requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal cannula which channels oxygen from the concentrator to the subject. Inogen One® G4 is designed to provide a flow of high purity oxygen. Inogen One® G4 may be used in home, institution, vehicle and various mobile environments.

Questions about this trial

What is this clinical trial studying?

A study testing Inogen One® G4 in people with COVID-19, run by Inogen Inc. at 2 sites in Canada.

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 9 inclusion and 6 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: finished, as of the sponsor's last update on 14 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

COVID-19 related brain hypoxia and peripheral oxygen saturation (time frame: 14+/-3 days). The study lists 4 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 14 Jul 2023.
