Study summary

The objective of this Registry is to provide ongoing safety and effectiveness assessment of the Zephyr Valve treatment of adult patients with Chronic Obstructive Pulmonary Disease (COPD) Grade III and Grade IV in order to support the renewal of the inscription of the Zephyr Valve on the list LPPR (Art 165-1) in France.

Read the detailed description

This is a multi-center, single-arm, prospective Registry to be conducted at a minimum of 12 study centers. Approximately 150 patients with severe emphysema undergoing Zephyr Valve treatment will be enrolled and followed out to 3 years. Assessments will be performed at 45-days, 6-months, 12-months, 24-months and 36-months post-procedure.

Patients prescribed the Zephyr Valve treatment will be consented and will be enrolled only after determination of little to no collateral ventilation between target and ipsilateral lobes. Safety and effectiveness of the Zephyr Valve treatment will be evaluated post-treatment based on data collected out to 3-years post-treatment.

Study population

This is an all-comers Registry. Physicians at participating study centers will invite consecutive patients who are prescribed Zephyr Valve treatment to participate in the Registry and allow data collection.

Inclusion criteria

  • Patients with emphysema (COPD Grade III and Grade IV) considered appropriate for the bronchoscopic lung volume reduction procedure by the physician.
  • Subjects who signed an Informed Consent Form to allow data collection.

Exclusion criteria

Exclusion Criteria:

  • Subjects determined to have collateral ventilation between the target(s) and ipsilateral lobe(s).

What researchers measure

Primary outcomes

  1. Forced Expiratory Volume in 1 second (FEV1)

    The percent of patients achieving an improvement in the post-bronchodilator FEV1 of ≥12% at 12-months.

    Time frame: 12 months

Secondary outcomes

  1. Treated Lobar Volume Reduction (TLVR)

    Treated Lobar Volume Reduction (TLVR) assessed by High Resolution Computed Tomography (HRCT) at 45-days.

    Time frame: 45 days

Other outcomes

  1. Absolute Change in Forced Expiratory Volume in 1 second FEV1 Post-Bronchodilator

    Absolute Change in FEV1 from Baseline to 6-months, 12-months, 24-months and 36-months.

    Time frame: Baseline, 6-months, 12-months, 24-months and 36-months

  2. Percent Change in Forced Expiratory Volume in 1 second FEV1 Post-Bronchodilator

    Percent change in FEV1 from Baseline to 6-months, 12-months, 24-months and 36-months.

    Time frame: Baseline, 6-months, 12-months, 24-months and 36-months

  3. Absolute Change in Residual Volume (RV)

    Absolute Change in Residual Volume (RV) from Baseline to 6-months, 12-months, 24-months and 36-months.

    Time frame: Baseline, 6-months, 12-months, 24-months and 36-months

  4. Percent Change in Residual Volume (RV)

    Percent change in Residual Volume (RV) from Baseline to 6-months, 12-months, 24-months and 36-months.

    Time frame: Baseline, 6-months, 12-months, 24-months and 36-months

  5. Absolute Change in St. George's Respiratory Questionnaire (SGRQ) Total Score

    Absolute change in St. George's Respiratory Questionnaire (SGRQ) from Baseline to 6-months and 12-months. The St. George's Respiratory Questionnaire measures health status (quality of life) in patients with diseases of airways obstruction. Scores range from 0 to 100, with higher scores indicating more limitations.

    Time frame: Baseline, 6-months and 12-months

  6. Percent Change in St. George's Respiratory Questionnaire (SGRQ) Total Score

    Percent change in St. George's Respiratory Questionnaire (SGRQ) Total Score from Baseline to 6-months and 12-months. The St. George's Respiratory Questionnaire measures health status (quality of life) in patients with diseases of airways obstruction. Scores range from 0 to 100, with higher scores indicating more limitations.

    Time frame: Baseline, 6-months and 12-months

  7. Absolute Change in Modified Medical Research Council (mMRC)

    Absolute Change in the Modified Medical Research Council (mMRC) Dyspnea Scale from Baseline to 6-months and 12-months. The mMRC (Modified Medical Research Council) stratifies severity of dyspnea in respiratory diseases. The severity of dyspnea is rated on a scale of 0 to 4, with higher scores indicating more limitations.

    Time frame: Baseline, 6-months and 12-months

  8. Percent Change in Modified Medical Research Council (mMRC)

    Percent change in the Modified Medical Research Council (mMRC) Dyspnea Scale from Baseline to 6-months and 12-months. The mMRC (Modified Medical Research Council) stratifies severity of dyspnea in respiratory diseases. The severity of dyspnea is rated on a scale of 0 to 4, with higher scores indicating more limitations.

    Time frame: Baseline, 6-months and 12-months

  9. Absolute Change in Six-Minute Walk Distance (6MWT)

    Absolute change in Six-Minute Walk Distance (from 6MWT) from Baseline to 6-months and 12-months.

    Time frame: Baseline, 6-months and 12-months.

  10. Percent Change in Six-Minute Walk Distance (6MWT)

    Percent change in Six-Minute Walk Distance (from 6MWT) from Baseline to 6-months and 12-months.

    Time frame: Baseline, 6-months and 12-months.
