Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if bronchoscopic lung volume reduction with endobronchial thermal liquid ablation (ETLA) works to treat severe emphysema in terms of feasibility and safety.

Participants will:

* Have up to two ETLA procedures
* Complete five clinic follow-up visits and two virtual follow-up visits.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

ETLA offers the potential to result in significant lung volume reduction of hyperinflated emphysematous regions, providing clinically meaningful improvement in pulmonary function and quality of life to a broad population of patients with severe emphysema. The REDUCE EU Pilot study will primarily evaluate the feasibility and safety of ETLA treatment in patients with severe emphysema. Secondarily, the study will evaluate the efficacy of sequential ETLA treatment.

Study Groups

Endobronchial Thermal Liquid Ablation (ETLA) Treatment

Participants will undergo up to two ETLA procedures separated by a minimum three-month interval.

Group Type EXPERIMENTAL

Endobronchial Therman Liquid Ablation (ETLA)

Intervention Type DEVICE

The ETLA System is a minimally invasive bronchoscopic treatment designed to deliver heated normal saline to targeted emphysematous lung regions with hyperinflation to cause tissue ablation and subsequent volume reduction as a means for treating emphysema. The ETLA procedures will be performed under general anesthesia. Each procedure will be limited to treatment in a single lung, with either unilateral or bilateral treatment over the two procedures.

* Total lung capacity (TLC) ≥ 100% predicted
* Residual volume (RV) ≥ 175% predicted
* 6 Minute Walk Distance (6MWD) ≥ 140 meters
* Dyspnea scoring ≥ 1 on the modified Medical Research Council scale (mMRC)
* Blood gas values of PCO2 ≤ 55 mmHg; PO2 ≥ 45 mmHg on room air
* Optimized medical management (consistent with GOLD guidelines) as confirmed by the Investigator
* Non-smoking for 3 months prior to study enrollment, as confirmed by lab testing
* Participant must engages in physical exercise beyond activities of daily living (i.e., a walking program, pulmonary rehabilitation) on n a regular basis for more than 6 weeks prior to enrollment and agree to continue the activity throughout study participation
* Participant must live within approximately 1 hour of the study hospital, or live within 1 hour of adequate regional care, or be willing to remain in the hospital for at least five days post-procedure
* Vaccinated for COVID-19, pneumococcus, and influenza (per European Union and Member State guidelines) or documented clinical intolerance or documented patient refusal
* Cognitively able to provide written informed consent and willing to comply with study requirements
* Severe emphysematous lung subsegments eligible for ETLA treatment

Exclusion Criteria

* Body mass index (BMI) \< 16 kg/m\^2 or ≥ 33 kg/m\^2

* History of bleeding disorders or enhanced predisposition to bleeding
* History of severe/massive hemoptysis defined as \>200ml of blood loss in \< 24 hours
* Unable to discontinue anti-coagulants or platelet inhibitors (acetylsalicylic acid \[ASA\]and non-ASA, including low dose) for at least 7 days prior to each procedure (or as per physician discretion based on the specific agent) and for at least 6 weeks after each procedure
* Daily systemic steroids equivalent to \> 15mg prednisolone
* Immunosuppressive drugs, such as for the treatment of cancer, autoimmune disease, or prevention of tissue/organ rejection
* Pregnant, lactating, or women of childbearing potential that plan to become pregnant within the study duration
* Currently enrolled in another trial studying an experimental treatment
* Any disease or condition likely to limit survival to less than one year
* Concomitant illnesses or medications that may pose a significant increased risk for complications following treatment with ETLA

* Active aspergillus infection
* Clinically significant bronchiectasis as determined by the Investigator
* Radiological evidence of bronchiectasis in target region(s) and/or cystic radiological bronchiectasis in any region of the lungs
* Clinically significant pulmonary fibrosis
