Discovery of the Impact of Targeted Lung Denervation (TLD) on the Severe and Very Severe COPD Population (DISCOVER TLD)

February 14, 2019 updated by: Nuvaira, Inc.
The DISCOVER TLD study is a multicenter, prospective, single-arm study designed to record the clinical outcomes of the CE-marked Nuvaira™ Lung Denervation System, in a subset of its CE-marked approved indication. This study is being conducted in Europe.

Study Overview

Status

Status

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Withdrawn

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

The purpose of this study is to evaluate the overall COPD patient experience with the Nuvaira™ Lung Denervation System and allow for the continued collection of safety and effectiveness data on the CE-marked product. The study is a multicenter, prospective, single-arm study designed to include patients, on average, who fall within a more severe stage of COPD, defined as 20-45% FEV1 percent predicted. Subjects will remain on respiratory medications per their standard of care and will be followed and tested per standard of care throughout the study.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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

40 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with diagnosis of advanced COPD [20% ≤ FEV1 ≤ 45% and FEV1/FVC < 70% (post-bronchodilator)] who are no longer smoking (quit at least 2 months prior to registry consent) and are able to undergo general anesthesia. All subjects will undergo a CT scan to determine whether bronchial anatomy is appropriate for TLD procedure.

Description

Inclusion Criteria:

  • Diagnosis of COPD with 20% ≤ FEV1 ≤ 45% and FEV1/FVC < 70% (post-bronchodilator)
  • History of long-term smoking, but non-smoking for a minimum of 2 months prior to study consent
  • Patient is a candidate for bronchoscopy
  • Patient agrees to all follow-up and provides written informed consent.

Exclusion Criteria:

  • Presence of lung or chest implants (eg. metal stent, valves, coils)
  • Pregnancy
  • Pre-existing pulmonary hypertension
  • Patient has a pacemaker, internal defibrillator, or other implantable electronic device
  • Inappropriate bronchial anatomy for procedure (per CT scan)
  • Previous abdominal surgical procedures on stomach, esophagus or pancreas
  • Previous treatment with TLD Therapy (in same areas)
  • Known allergy to bronchoscopy or general anesthesia medications
  • Inability to tolerate single lung ventilation for at least 2 min, 30 sec
  • Patient has a GCSI score of ≥ 18 at time of screening visit

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.
TLD Procedure
All subjects who are enrolled and meet the eligibility criteria will undergo Targeted Lung Denervation (TLD). TLD is a bronchoscopically-guided, minimally-invasive procedure using the Nuvaira™ Lung Devervation System. The Nuvaira System is intended for the long-term maintenance treatment of airway obstruction associated with COPD. TLD uses radiofrequency (RF) energy to ablate the airway nerve trunks of the vagus nerves that travel parallel to and outside of the main bronchi and into the lungs. Ablation of the nerves opens the airways and makes breathing easier.
Device: Targeted Lung Denervation (TLD)
Targeted Lung Denervation (TLD) procedure.

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
Change in Quality of Life (QOL)
Time Frame: 6 months; 12 months; 24 months post-procedure
Changes in the St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) over time will be assessed. Comparisons will be made to baseline score.
6 months; 12 months; 24 months post-procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Pulmonary Function
Time Frame: 6 months, 12 months, 24 months post-procedure
Basic spirometry tests including FEV1, FVC, forced impulse oscillometry, nitrogen wash-out measures will be performed per standard of care over time. Comparisons will be made to baseline measures.
6 months, 12 months, 24 months post-procedure
Change in 6-Minute Walk Test
Time Frame: 6 months, 1 year, 2 years
Change in 6MWT over time
6 months, 1 year, 2 years
Respiratory-related Adverse Events
Time Frame: 24 months
Respiratory-related adverse events will be collected throughout the registry. Rates of respiratory-related adverse events will be reported and compared to historical data.
24 months
Freedom from Device-related Adverse Events
Time Frame: Peri-procedure (within 7 days); 1 month and 6 months
Device-related adverse events will be collected through 6 months post-procedure. The number of subjects free from a device-related adverse event will be reported.
Peri-procedure (within 7 days); 1 month and 6 months

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2017

Primary Completion (Anticipated)

Primary Completion

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.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
