What is this study?

The objective of this study is to assess the safety and efficacy of Apreo BREATHE system when used to support native airways and release trapped air in the treatment of adult COPD patients with emphysema suffering from dyspnea due to hyperinflation despite optimal medical treatment. The Apreo BREATHE Airway Scaffold is a permanent implant designed to tent open native airways.

It is , overseen by an independent and licensed medical staff.

The objective of this study is to assess the safety and efficacy of Apreo BREATHE system when used to support native airways and release trapped air in the treatment of adult COPD patients with emphysema suffering from dyspnea due to hyperinflation despite optimal medical treatment. The Apreo BREATHE Airway Scaffold is a permanent implant designed to tent open native airways. The study will include up to 250 participants at up to 25 study centers located in the United States and Europe. Study subjects will be followed for 3 years. The main questions it aims to answer are: Is it safe? Does it work?

Who this study is looking for

In plain language, from the study's own rules. The study team confirms the full details with you — this isn't a final yes or no.

✅ You may be able to join if…

  • Adults with COPD and emphysema who have shortness of breath from lung over-inflation despite best medical care
  • Age 40 to 84 (inclusive)
  • BMI 18 to 32 (inclusive)
  • mMRC score of 2 or higher (a breathlessness score described in the study)
  • Lung scan and breathing test results showing emphysema and air trapping, plus ability to walk at least 100 meters in 6 minutes

🚫 You may not be able to join if…

  • Unresolved lower lung infection (examples include pneumonia, MAI, fungus, or tuberculosis)
  • Steroid-dependent condition needing about 10 mg or more of oral corticosteroid per day
  • Very severe emphysema damage in both lungs based on the study’s CT scan limits
  • Too much carbon dioxide or too little oxygen while breathing room air (PaCO2 >50 mmHg or PaO2 ≤45 mmHg)
  • Pregnant, breastfeeding, or planning pregnancy during the study (childbearing potential)

Are you a good fit?

Simplified highlights. The study team always confirms the full details with you.

  • Adults roughly 40–84
  • A BMI around 18 or higher
  • Have Obesity / overweight or COPD (chronic lung disease)
  • !Some conditions may not be a fit: Heart / cardiovascular disease, High blood pressure, Asthma
  • !Not for people who are pregnant or breastfeeding

What to expect, step by step

  1. 1

    Usually a few weeks

    The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.

  2. 2

    Treatment

    If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.

  3. 3

    Follow-up

    After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.

What you need to know before you apply

What is this study testing?+

The objective of this study is to assess the safety and efficacy of Apreo BREATHE system when used to support native airways and release trapped air in the treatment of adult COPD patients with emphysema suffering from dyspnea due to hyperinflation despite optimal medical treatment. The Apreo BREATHE Airway Scaffold is a permanent implant designed to tent open native airways.

Is it safe? Who makes sure of that?+

This is a research study. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.

Will I get a placebo instead of the real treatment?+

Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.

Do I have to stop taking my current medications?+

It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.

Does it cost anything? Will I be paid?+

Study-related care is provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.

Do I need insurance? Will anyone ask about my immigration status?+

No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.

What if English isn't my first language?+

You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.

Is my information private?+

Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.

Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
