NCT05118269

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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).

    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.

    12 months

Secondary Outcomes (19)

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

    12 months, 18 months, 24 months

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

    12 months, 18 months, 24 months

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

    12 months, 18 months, 24 months

  • Improvement in other measures of pulmonary function- Forced Vital Capacity(FVC) change- at 12, 18 and 24 months

    12 months, 18 months, 24 months

  • Improvement in other measures of pulmonary function- Forced Vital Capacity Percent Predicted change- at 12, 18 and 24 months

Study Arms (2)

Treatment plus Optimal Medical Therapy

EXPERIMENTAL

Patients will be treated with the InterVapor System and Optimal Medical Therapy

Device: Treatment plus Optimal Medical Therapy

Optimal Medical Therapy (Control)

ACTIVE COMPARATOR

Patients will be treated according to Optimal Medical Therapy

Other: Optimal Medical Therapy

Interventions

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).

  • minute walk distance (6MWD) \> 100m and ≤ 450m
  • (Partial Pressure of Oxygen) PaCO2 ≤ 45 mm Hg; PaO2 \> 45 mm Hg on room air
  • Non-smoking for 4 months prior to study enrollment as confirmed by:
  • negative urine analysis or serum cotinine level of ≤ 10 ng/mL, or negative CO Hb test OR
  • If using smoking cessation product(s) containing nicotine at screening, serum cotinine level ≤ 13.7 ng/ml (or arterial carboxyhemoglobin ≤ 2.5%)

  • b. Evidence of completed Pulmonary Rehabilitation
  • ≥ 6 weeks out-patient or ≥ 3 weeks in-patient within 12 months of enrollment; or,
  • +2 more criteria

You may not qualify if:

  • DLCO \< 20% predicted
  • Uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure \>45 mm Hg) or evidence or history of cor pulmonale as determined by recent echocardiogram
