About this study

Official title: Comparison of Effects of Bi-level Positive Airway Pressure Therapy and Nocturnal Oxygen Therapy on Right and Left Ventricular Hemodynamics in Overlap Syndrome (Co-existent Chronic Obstructive Airway Disease and Obstructive Sleep Apnea)

Patients with both sleep apnea and COPD have overlap syndrome, but their optimal management is not known. We plan to conduct a randomized trial of of bi-level PAP vs. night time oxygen to asses the impact of intervention on cardiac MRI and biomarkers.

Read the detailed description

Presence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in the same patient has been termed overlap syndrome, affecting 1% of the U.S. population. Despite the high prevalence of overlap syndrome, little research has been done in this field. Overlap syndrome has been recently reported to have higher death rate than COPD alone, which is due to effect on the heart. However, the mechanisms by which overlap syndrome affects the heart are not known well. Also, the ideal treatment for overlap syndrome is not known.

This study is being done to find the mechanisms by which overlap syndrome affects the right and left sides of heart (using cardiac MRI to study the heart). We will also compare the effect of treatment with bi-level positive airway pressure device (BPAP) vs. night-time oxygen on heart in overlap syndrome. These aims will allow us to test the hypothesis that overlap syndrome patients have worse heart function than COPD only or OSA only, and treatment with BPAP device will improve the heart function better than oxygen only.

At the baseline visit, the subject will undergo an overnight sleep study in the hospital. In the morning, blood draw to measure serum inflammatory biomarkers (C-Reactive Protein, interleukin-6, P-selectin, ICAM-1, TNF-alpha), urine catecholamine level, six-minute walk test, questionnaire for health-related quality of life score and modified Medical Research Council (MMRC) dyspnea score, lung function tests, ultrasound of forearm blood vessels and cardiac MRI will be done. No follow-up visit is needed if the subject does not have sleep apnea. If the subject has sleep apnea based on the sleep study, he/she will be allotted to treatment with a BPAP device or night-time oxygen for 6 months. If the subject does not want to be treated with BPAP or oxygen, CPAP device will be used to treat sleep apnea. During the duration of study treatment, phone calls and a brief study visit at 3 months will be done to make sure there is no discomfort related to the treatment. After 6 months of study treatment, cardiac MRI, ultrasound of forearm blood vessels, lung function tests, blood draw for serum inflammatory biomarkers, urine catecholamine level, six-minute walk test, and questionnaires for dyspnea score and quality of life score will be repeated.

This study will help us in better understanding of mechanisms of high death rate due to effects on the heart in overlap syndrome. It will also help us in understanding better ways to treat sleep apnea in COPD patients.

What participants receive

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

  • Bi-level positive airway pressure (BPAP)Device

    The level of BPAP will be titrated to treat OSA as well as hypoxemia and hypercapnia. The duration of therapy will be six months.

  • OxygenDrug

    Oxygen will be titrated to keep resting oxygen saturation (as measured by pulse oximeter) more than 88 percent. The duration of therapy will be six months.

  • CPAPDevice

    The level of CPAP will be titrated to treat OSA. The duration of therapy will be six months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Bi-level positive airway pressure (BPAP), Oxygen and CPAP in people with Chronic Obstructive Airway Disease, run by Brigham and Women's Hospital at 2 sites in United States.

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 2 inclusion and 10 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: withdrawn, as of the sponsor's last update on 12 Jan 2017. 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 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 withdrawn before enrolling participants, so there are no results.

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?

Right ventricular end-diastolic volume (time frame: Six months). 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 Jan 2017.
