November 14, 2023 updated by: Pulmonx Corporation

Post-Market Clinical Evaluation of the Zephyr Valve 5.5-LP EBV for Bronchoscopic Lung Volume Reduction (BLVR) Procedures

This is a Post-Market Evaluation of the Zephyr Valve 5.5-LP EBV to assess Treated Lobar Volume Reduction (TLVR), changes in lung function and the safety profile of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-center, single-arm, prospective, observational study. Approximately 70 study participants undergoing Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV will be enrolled and followed out to 3 months. Assessments will be conducted at 45 days and 3 months. The evaluation will be conducted at up to 6 sites.

Patients prescribed Zephyr Valve treatment for their emphysema will be consented and will be enrolled only after: 1) determination of little to no collateral ventilation between target and ipsilateral lobes and 2) implantation of at least one Zephyr Valve 5.5-LP EBV. Baseline data will be collected retrospectively after enrollment of a patient in the Post-Market Evaluation. Performance and safety of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP will be evaluated post-treatment based on data collected until 3 months after the treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The population evaluated will comprise of patients with hyperinflation associated with severe emphysema that are considered appropriate for the procedure by their physician, confirmed to have little to no collateral ventilation and had at least one Zephyr Valve 5.5-LP EBV implanted during the procedure.

Description

Inclusion Criteria:

  • Patients with severe emphysema prescribed treatment with Zephyr Valves
  • Zephyr Valve Treatment with the use of at least one Zephyr Valve 5.5-LP EBV

Exclusion Criteria:

  • Patients determined to have collateral ventilation between the target(s) and ipsilateral lobe(s).
  • Patients who undergo Zephyr Valve treatment, but no Zephyr Valve 5.5-LP EBV implanted.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Treatment
Patients undergoing Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.
Device: The Pulmonx Zephyr Endobronchial Valve (EBV) 5.5- LP
The Zephyr Valves are implantable bronchial valves intended to control airflow in order to improve lung function in patients with hyperinflation associated with severe emphysema and/or to reduce air leaks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treated Lobar Volume Reduction (TLVR) responders
Time Frame: 45 days
The percentage of patients treated with the Zephyr Valve 5.5-LP EBV who achieved a Treated Lobar Volume Reduction (TLVR) of the treated lobe (s) of ≥350ml as seen via HRCT at 45-days.
45 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
