NEUWAVE Flex Microwave Ablation System in the Ablation of Primary Soft Tissue Lesions of the Lung

December 18, 2020 updated by: Ethicon, Inc.

A Multicenter Study of the NEUWAVE Flex Microwave Ablation System in the Ablation of Medically Inoperable Primary Soft Tissue Lesions of the Lung: An Initial Experience

Patients with medically inoperable primary soft tissue lesion of the lung will have transbronchial microwave ablation performed via transbronchial approach by an interventional pulmonologist or thoracic surgeon using CT imaging. Prior to the ablation procedure, the treating physician will use endobronchial ultrasound to confirm staging. Patients will be followed for one year following the ablation procedure for efficacy and safety.

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

Patients with medically inoperable primary soft tissue lesion of the lung (lesions less than or equal to 2cm and located in the outer two-thirds of the lung and not closer than 1cm to the pleura) will have transbronchial microwave ablation performed using CT imaging. All ablations will be performed under general anesthesia via transbronchial approach by an interventional pulmonologist or thoracic surgeon.

Prior to the ablation procedure, the treating physician will use endobronchial ultrasound to confirm staging.

Patients will be followed for one year following the ablation procedure for efficacy and safety with specific follow-up visits at 30 days, 6 months, and 12 months post-ablation. A user experience questionnaire is completed by the treating physician to better understand the ease of the procedure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  4. Willing to fulfill all follow-up visit requirements.
  5. Medically inoperable primary soft tissue lesion of the lung or patient election not to have surgery. (Medically inoperable is defined per the following indicators: post op predictive FEV1 (forced expiratory volume in 1 second) < 40%; DLCO (diffusing capacity of the lung for carbon monoxide) < 40%; hypoxemia or hypercapnia diabetes with end-organ damage; or severe cerebral, cardiovascular, peripheral vascular disease, or chronic heart disease)

  6. One soft tissue lesion ≤ 2 cm in the outer two thirds of the lung and not closer than 1 cm to the pleura.

    (Outer two thirds of the lung is defined as peripheral beyond the segmental airway, past the segmental bronchi, such that proximal endobronchial soft tissue lesions are avoided; soft tissue lesions should not be contiguous with the pleura)

  7. Radiographic resolution of pneumonia

Exclusion Criteria:

  1. Scheduled concurrent procedure for the target soft tissue lesion other than those that are lung related.
  2. Pregnant or breastfeeding.
  3. Physical or psychological condition that would impair study participation.
  4. Patients with uncorrectable coagulography at time of screening.
  5. Patient with implantable devices, including pacemakers or other electronic implants.
  6. Prior pneumonectomy or bronchiectasis.
  7. Severe neuromuscular disease.
  8. Platelet count ≤ 50,000/mm3.

  10. Inability to tolerate anesthesia.
  11. Expected survival less than 6 months.
  12. Clinically significant hypertension.
  13. Chronic ventilator support, which uses bi-level positive airway pressure (PAP).
  14. Endobronchial soft tissue lesions proximal to the segmental airways

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
Number of Patients Whose Ablation Resulted in Technical Success
Time Frame: Immediately post-ablation (day 0)
Ablation of the target lesion according to the protocol and covered completely, with an adequate margin, as defined by the performing physician (that is, the ablation zone completely overlaps or encompasses the target lesion plus an ablative margin), as assessed by CBCT imaging, immediately following the procedure.
Immediately post-ablation (day 0)
Number of Patients Whose Ablation Resulted in Technique Efficacy
Time Frame: 30 days post-ablation
Ablation of the target lesion according to the protocol and covered completely, with an adequate margin, as defined by the performing physician (that is, the ablation zone completely overlaps or encompasses the target lesion plus an ablative margin), as assessed by CT imaging, 30 days (+/- 7 days) after the first ablation procedure.
30 days post-ablation
User Experience Survey (Part I)
Time Frame: Immediately post-ablation
A Sponsor-created survey completed by the treating physician immediately post-ablation. Questions were all YES/NO.
Immediately post-ablation
User Experience Survey (Part II)
Time Frame: Immediately post-ablation
A Sponsor-created survey completed by the treating physician immediately post-ablation. This question asked the time it took to place the probe in a position that was ready for ablation.
Immediately post-ablation
User Experience Survey (Part III)
Time Frame: Immediately post-ablation
A Sponsor-created survey completed by the treating physician immediately post-ablation. This question asked how many cone-beam CT (CBCT) scans were taken to place the probe such that it was ready for ablation.
Immediately post-ablation
User Experience Survey (Part IV)
Time Frame: Immediately post-ablation
A Sponsor-created survey completed by the treating physician immediately post-ablation. This question asked the distance of the tip of the probe to the center of the soft-tissue lesion (in mm) just before the ablation procedure was initiated.
Immediately post-ablation
User Experience Survey (Part V)
Time Frame: Immediately post-ablation
A Sponsor-created survey completed by the treating physician immediately post-ablation. This question asked how many times the probe had to be repositioned to complete the ablation procedure.
Immediately post-ablation

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
