Emphysema or COPD Clinical Trial

Official title: A Pilot Study to Assess Treatment of Patients With Homogeneous Emphysema Using Sequential Segmental Bronchoscopic Thermal Vapor Ablation

Status Completed

Clinical Trial Summary

This study is a Prospective, single arm, single center pilot study following outcomes for 12 months after initial BTVA treatment. The primary objectives of the study are to prospectively document the safety and efficacy of sequential segmental treatment with BTVA in patients with a homogeneous distribution of emphysema that are not candidates for endobronchial valve therapy.

Clinical Trial Description

The study will include patients with severe emphysema as defined by pulmonary function tests, a homogeneous distribution of emphysema as determined by CT, who are not eligible for endobronchial valve therapy based on fissure integrity as determined by CT. Enrollment will continue until 10 patients have been treated per protocol or until a maximum of 15 patients total have been treated.

Patients will be enrolled at Thoraxklinik University of Heidelberg, Germany and followed for twelve (12) months.

The follow up data collected will include pulmonary function testing (spirometry, body plethysmography, DLCO), exercise capacity (six minute walk test) and imaging findings (chest x-ray and CT). Dyspnea score (mMRC) and quality of life questionnaire (SGRQ-C) information will be obtained. Information regarding adverse events, serious adverse events, and major medical complications will be collected at each visit. Serious adverse events will be adjudicated by an independent medical monitor in order to establish relatedness to the InterVapor device and procedure.

Descriptive statistics will be used to summarize all safety and efficacy data. There is no predefined hypothesis regarding safety, or efficacy.

Monitoring of the study will be undertaken as a continuous process to ensure that high-quality data are obtained and to ensure compliance with study procedures. ;
