About this study

Official title: A Pilot Study to Assess Treatment of Patients With Homogeneous Emphysema Using Sequential Segmental Bronchoscopic Thermal Vapor Ablation

This study is a Prospective, single arm, single center pilot study following outcomes for 12 months after initial BTVA treatment. The primary objectives of the study are to prospectively document the safety and efficacy of sequential segmental treatment with BTVA in patients with a homogeneous distribution of emphysema that are not candidates for endobronchial valve therapy.

Read the detailed description

The study will include patients with severe emphysema as defined by pulmonary function tests, a homogeneous distribution of emphysema as determined by CT, who are not eligible for endobronchial valve therapy based on fissure integrity as determined by CT. Enrollment will continue until 10 patients have been treated per protocol or until a maximum of 15 patients total have been treated.

Patients will be enrolled at Thoraxklinik University of Heidelberg, Germany and followed for twelve (12) months.

The follow up data collected will include pulmonary function testing (spirometry, body plethysmography, DLCO), exercise capacity (six minute walk test) and imaging findings (chest x-ray and CT). Dyspnea score (mMRC) and quality of life questionnaire (SGRQ-C) information will be obtained. Information regarding adverse events, serious adverse events, and major medical complications will be collected at each visit. Serious adverse events will be adjudicated by an independent medical monitor in order to establish relatedness to the InterVapor device and procedure.

Descriptive statistics will be used to summarize all safety and efficacy data. There is no predefined hypothesis regarding safety, or efficacy.

Monitoring of the study will be undertaken as a continuous process to ensure that high-quality data are obtained and to ensure compliance with study procedures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of SAEs, Major Medical complications, and unanticipated serious adverse device effects (USADEs) (safety endpoint)

    Occurrence of SAEs, Major Medical complications, and unanticipated serious adverse device effects (USADEs) (safety endpoint)

    Measured: Baseline to 6 months

  2. Change in FEV1 (efficacy endpoint)

    Change in FEV1 (efficacy endpoint)

    Measured: Baseline to 6 months

  3. Change in St Georges Respiratory Questionnaire for COPD Patients (SGRQ-C) score (efficacy endpoint)

    This trial will utilize the SGRQ-C which is a shortened version of the SGRQ questionnaire. The SGRQ is a validated, disease-specific questionnaire that measures health-related quality of life in patients with COPD.

    The instrument has 3 domains (activity, symptoms, and impacts) and a total score. A Total and three-component scores are calculated: Symptoms; Activity; Impacts. Each questionnaire response has a unique empirically derived 'weight'. The lowest possible weight is zero and the highest is 100. Each component of the questionnaire is scored separately. Sum of maximum possible weights for each component and Total: Symptoms 566.2, Activity 982.9, Impacts 1652.8. Total (sum of maximum for all three components) 3201.9 Higher weights indicate worse outcomes. The difference in the domain scores and total score at follow-up visits relative to baseline will be calculated and reported.

    Measured: Baseline to 6 months

Secondary outcomes (9)
  1. Change in FVC

    Change in Forced Vital Capacity

    Measured: Baseline to 6 months

  2. Change in FRC

    Change in Forced Residual Capacity

    Measured: Baseline to 6 months

  3. Change in RV

    Change in Residual Volume

    Measured: Baseline to 6 months

  4. Change in TLC

    Change in Total Lung Capacity

    Measured: Baseline to 6 months

  5. Change in RV/TLC

    Change in Residual Volume/Total Lung Capacity

    Measured: Baseline to 6 months

  6. Change in DLCO

    Change in Diffusing capacity of the lung for carbon monoxide

    Measured: Baseline to 6 months

  7. Change in Modified Medical Research Council (mMRC) Dyspnea scale

    Change in dyspnea score.

    Grade Degree of Breathlessness Related to Activities Grade 0 No breathlessness except with strenuous exercise Grade 1 Breathlessness when hurrying on the level or walking up a slight hill Grade 2 Walks slower than people of the same age on the level because of breathlessness or has to stop for breath when walking at own pace on the level Grade 3 Stops for breath after walking about 100 yards or a few minutes on the level Grade 4 Too breathless to leave the house or breathless when dressing or undressing Max score=4, Min score=0 One score is reported based on grade. Higher values represent worse outcomes. For patients with a higher mMRC grade (e.g. ≥2) and clinical circumstances consistent with respiratory disease, measuring spirometry (e.g., FEV₁ and FVC), determining the patient's GOLD stage, helps guide therapeutic interventions.

    Measured: Baseline to 6 months

  8. Change in 6MWD

    Change in six minute walk distance

    Measured: Baseline to 6 months

  9. Change in volume of the treated lobe(s)

    Change in lung volume assessed by CT

    Measured: Baseline to 6 months

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of SAEs, Major Medical complications, and unanticipated serious adverse device effects (USADEs) (safety endpoint) (time frame: Baseline to 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03670121, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Nov 2021.
