A Randomized Controlled Trial of InterVapor® in France - The TARGET Trial

Uptake Medical Technology, Inc.3 enrolled

Overview

This study is designed to prospectively document changes in FEV1 and health-related quality of life 12 months following sequential segmental treatment with InterVapor® in patients with heterogeneous emphysema with upper lobe predominance. For validity of the study, the results will be compared to patients that receive optimal medical therapy.

The primary objectives are to prospectively document changes in FEV1 and health-related quality of life 12 months following sequential segmental treatment with Bronchoscopic Thermal Vapor Ablation (BTVA) using the InterVapor system in patients with heterogeneous emphysema with upper lobe predominance. The French TARGET trial is a prospective, multi-center, single blind, randomized controlled study. 150 participants will be enrolled in the study (1:1 randomization with 75 InterVapor, 75 controls) with a 24-month follow-up period. Subjects randomized to the Control Group may be allowed to cross over to the treatment group and offered the InterVapor treatment once they have completed the protocol defined 12-month follow-up period.

Interventions

Treatment plus Optimal Medical TherapyDEVICE

Patients will be treated with the InterVapor System in 1 to 2 segments in the upper lobes of each lung (2 to 3 segments total). Patients will also receive Optimal Medical Therapy. Guidelines for prescribing medical treatment for emphysema are published by the American Thoracic Society (ATS) and the National Heart Lung and Blood Institute/World Health Organization (NHLBI/World Health Organization , Global Initiative for Chronic Obstructive Lung Disease (GOLD) workshop summary).

Optimal Medical TherapyOTHER

Patients will receive Optimal Medical Therapy. Guidelines for prescribing medical treatment for emphysema are published by the American Thoracic Society (ATS) and the National Heart Lung and Blood Institute/World Health Organization (NHLBI/WHO GOLD workshop summary).

Outcomes

Primary Outcomes

Changes in FEV1 between Treatment vs Control at 12 months

Percentage change in Forced expiratory volume in 1 second (FEV1) compared to active comparator: Change in FEV1, percent change from baseline to 12 months in FEV1, where FEV1 is expressed in raw units of volume (mL).

Time frame: 12 months

St. George's Respiratory Questionnaire for patients with Chronic Obstructive Pulmonary Disease (SGRQ-C) changes between Treatment vs Control at 12 months

Health-related Qualify of Life (SGRQ-C) compared to active comparator. This is calculated as change from baseline to 12 months in SGRQ-C Total Score. SGRQ-C scores range from 0 to 100. A higher score means a worse outcome.

Time frame: 12 months

Secondary Outcomes

Improvement in other measures of pulmonary function- Forced Expiratory Volume, absolute change- at 12, 18 and 24 months

Change in FEV1, abs: Absolute change from baseline to follow-up in FEV1, where FEV1 is expressed in raw units of volume (mL).

Time frame: 12 months, 18 months, 24 months

Improvement in other measures of pulmonary function- Forced Expiratory Volume, Percent change- at 12, 18 and 24 months

Change in FEV1, Percent Predicted value: Percent change from baseline to follow-up in FEV1, where FEV1 is expressed in percent predicted computed by European Respiratory Standard (ERS) standards.

Time frame: 12 months, 18 months, 24 months
