Call your doctor before leaving home if you think you’ve been exposed to COVID-19 or have symptoms

Due to the presence of COVID-19 in our community, visitor restrictions are in place for all Duke clinics and hospitals. For your safety and the safety of others, we recommend patients do not bring a visitor to Duke clinics, if at all possible. If a visitor must accompany a patient, only one individual over 12 years of age is allowed. Patients and visitors will be screened for symptoms upon arrival. Individuals with flu-like symptoms are not allowed. View the complete list of Visitor Restrictions.

Effective immediately, Duke Health is prioritizing and rescheduling some non-emergent or non-critical surgeries, procedures, and appointments. Check our COVID-19 (Coronavirus) page for updates.

What is the Purpose of this Study?

We are doing this study to learn if the study procedure, Targeted Lung Denervation, can help COPD flare-ups and potential hospitalizations.
What is the Condition Being Studied?
COPD The primary purpose of conducting this study is to evaluate if Targeted Lung Denervation (TLD)Therapy in addition to optimal medical care (daily breathing medications you have been prescribed by your doctor) is better at reducing a moderate or severe worsening of symptoms (known as an COPD flare-ups or exacerbations) and related hospitalizations than optimal medical care alone.

Who Can Participate in the Study?

- Have not smoked in 2 months
- Have a previous history of smoking
- Diagnosed with COPD
- Have had a flare-up that required medical treatment
- Have not had surgetry on stomach
- Do not have medical device implanted

Age Group

What is Involved?

-Be randomized (like flipping a coin) to either Group 1 or Group 2
--Group 1 will receive the study procedure, Targeted Lung Denervation (TLD) which is radiofrequency delivered to the nerves in addition to their daily breathing medications
--Group 2 will continue their optimal care and breathing medications
- Get a bronchoscopy
- Complete blood draws
- Get a flu shot once a year
- Do Pulmonary (Lung) Function Tests (PFTs)
