About this study

Official title: Efficacy and Safety of Long-term High-flow Nasal Cannula Oxygen Therapy in Stable COPD Patients with Home Oxygen Therapy (HOT): a Multicenter, Prospective, Randomized Controlled Study

This is a prospective, randomized parallel study for evaluation of the efficacy and safety of long-term nocturnal high-flow nasal cannula therapy (HFNC: with the myAIRVO2 as HFNC in this study) in stable COPD patients with the global initiative for chronic obstructive lung disease (GOLD) stage 2-4, PaCO2 >= 45 Torr and hypercapnia who require home oxygen therapy (HOT) using COPD exacerbation (Moderate or Severe).

Read the detailed description

An abroad study of the stable COPD patients was reported that HFNC usage decreased the frequency of COPD exacerbation.

In addition, the result of the pilot study (NCT02545855) of the stable COPD patient in Japan is indicated that HOT with HFNC improved their QOL and PaCO2 by comparing to HOT only.

Therefore, this study is planned to indicate the efficacy of HFNC which can increase the ventilation efficiency and have the function of heated humidification, by comparing HOT with HFNC to HOT only.

What participants receive

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

  • High-flow nasal cannula therapyDevice

    Also called myAIRVO2®

    Subjects will receive nocturnal high-flow nasal cannula therapy with the myAIRVO2®, in addition to their current Home oxygen therapy (HOT). The myAIRVO2® is used for at least 4 hours per day with flow rates in the range 30-40 L/min. The investigator can adjust the nocturnal oxygen flow rates to keep SpO2 88-92% stably. If the subjects report discomfort, the investigator can adjust the flow rates in the range at least 20 L/min.

  • Home oxygen therapy (HOT)Device

    All subjects will continue their current Home oxygen therapy (HOT) which kept original usage conditions at the time of enrollment throughout the entire duration of the study regardless of treatment arm assignment.

What is being measured

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

  1. Frequency (the number of occurrences per year) of COPD exacerbation (Moderate or Severe)

    COPD exacerbation will be assessed by the disease diary which is kept by each patient within the term of intervention.

    Measured: 52weeks

Secondary outcomes (16)
  1. Term from enrollment to the date of first COPD exacerbation (Moderate or Severe)

    The term from enrollment to the date of first COPD exacerbation is a duration from the start of intervention (Week0) to the date of first COPD exacerbation or death from any cause which ever comes first.

    The date of first COPD exacerbation will be assessed by the disease diary which is kept by each patient within the term of intervention.

    Measured: up to 52 weeks

  2. Term from enrollment to death from any cause

    Term from enrollment to death from any cause is a duration from the start of intervention (Week0) to death from any cause.

    Measured: up to 52 weeks

  3. Frequency (the number of occurrences per year) of COPD exacerbation (All Severity and Severe only)

  8. Dyspnea intensity: the modified medical research council (mMRC) score

    Dyspnea intensity will be evaluated by the modified medical research council (mMRC) score.

    Measured: 52weeks

  9. Arterial blood gas analysis (ABG): pH, PaO2, PaCO2, HCO3-, BE

    SpO2 will be evaluated by Pulse Oximeter.

    Measured: 52weeks

  11. Pulmonary functions: FVC, FEV1, FEV1%

    Lung function of the subjects will be assessed by the pulmonary function tests in the following indicators: vital capacity (VC, %VC), forced vital capacity (FVC, %FVC), forced expiratory volume in 1 second (FEV1, %FEV1), FEV1/FVC.

    Measured: 52weeks

  12. 6-minute walk test (6MWT)

    6MWT for the respiration rehabilitation is defined as the functional exercise capacity which is assessed by the following indicators: the distance (m), changes in pre- and post-6MWT pulse oximeter (SpO2), and post-6MWT modified borg scale.

    Measured: at 0, 12, 24 and 52 weeks

  13. Term from enrollment to the date of long-term (more than 1month) NPPV(Noninvasive Positive Pressure Ventilation) usage

    The term from the start of intervention (Week0) to the date of Long-term NPPV usage.

    Long-term NPPV usage is defined as more than 1month NPPV usage.

    Measured: 52weeks

  14. Flow rate(Oxygen / Total) (Arm A only)

    Oxygen flow rate / Total flow rate will be confirmed by the record of numerical value displayed on the device.

    Measured: 52weeks

  15. Total hours of myAIRVO2-use (Arm A only)

    Total hours of myAIRVO2-use will be confirmed by the record of numerical value displayed on the device.

    Measured: 52weeks

  16. Adverse events

    Adverse events will be determined by the latest version of MedDRA/J (Medical Dictionary for Regulatory Activities/J)at the time of Database lock.

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 6 inclusion and 15 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 20 Nov 2024. 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 Japan. 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?

Frequency (the number of occurrences per year) of COPD exacerbation (Moderate or Severe) (time frame: 52weeks). 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 NCT03282019, which also lists 1 linked publication.

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 20 Nov 2024.
