Clinical Investigation Evaluating the Performance, Safety and Clinical Benefit of the Endowave FlexAblate™ Microwave Ablation System in Patients Undergoing Lung Ablation Procedures.

The goal of this clinical trial is to learn if the FlexAblate™ Ablation System works to treat a lung cancer nodules and it will also learn about the safety of the ablation system.

Participants in this clinical trial will be patients aged over 18 years who have been previously diagnosed with cancer in the lung (primary or secondary malignant tumours) and deemed unsuitable for surgery or are declining surgery or, patients suitable for microwave ablation procedure based on clinical assessment.

Those who meet all of the eligibility criteria at a screening assessment (a review of eligibility to participate in the study includes review of information on the cancerous nodule, recording your medical history, current medications, a blood test, and quality of life assessments) will undergo the ablation treatment with FlexAblate™ Microwave Ablation System. Follow-up assessments will be at week 1 and months 1, 3, 6 and 12 will includes CT Scans (CT or "CAT" scan is a computed tomography scan), blood tests, assessment of overall health and quality of life assessments.

About this study

This is a prospective, single-arm, non-randomised clinical investigation. Up to 43 subjects will be enrolled from up to 5 sites. The clinical investigation is designed to evaluate the performance and safety of the Endowave FlexAblate™ Microwave Ablation System device in subjects undergoing lung ablation procedures. Microwave Ablation System device in subjects undergoing lung ablation procedures.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult ≥ 18 years of age who has provided signed informed consent.
  • Subject is able and willing to comply with the planned clinical investigation follow-up schedule
  • Pathological confirmed malignant nodule in the lung either primary or metastatic disease.
  • Target nodule is ≤ 20mm in maximum diameter.
  • There is ≥ 5mm of nodule-free lung parenchyma between target nodule and pleura or fissure.
  • Subject is a candidate for an elective lung ablation procedure as determined by institutional multi-disciplinary board or equivalent.
  • Subject or the lesion is not suitable for surgery or patient refuses surgery.

Exclusion criteria

  • Target nodule is abutting main or lobar stem bronchus, main pulmonary vasculature (vessel 5mm), heart, oesophagus and/or trachea.
  • Subjects who are extremely breathless or on home oxygen therapy.
  • Female subjects who are pregnant or nursing.
  • Subjects with uncorrectable coagulopathy or thrombocytopenia at time of screening.
  • Subjects with prior pneumonectomy.
  • Subjects who have had any radiation (i.e., SBRT or EBRT) to the intended ablation zone or lung ablation, surgical resection therapy, radiotherapy, or any other treating procedure within 30 days prior to the planned ablation procedure or those who plan to receive a lung ablation, surgical resection, or radiation therapy on the ablated lung side before completing the primary endpoint assessment (30 days post-ablation).
  • Subjects who have implantable electronic devices, including pacemakers or other electronic implants.
  • Known pulmonary hypertension (Pulmonary artery systolic pressure, PASP >50mmHg).
  • Active active pulmonary infection at time of screening or the procedure.
  • Subjects medically unable to stop anticoagulant or anti-platelet therapy for relevant time period prior to and following the ablation procedure.
  • Participation in an investigational drug or device clinical investigation within 30 days of enrolment that would interfere with this clinical investigation.
  • The investigator determines that participation in this clinical investigation may jeopardise the safety or welfare of the subject.

Treatment and study plan

microwave ablation

Device

FlexAblate Microwave Transbronchial Ablation System

Primary outcomes

  1. Technical Efficacy

    Time frame: 1 month

    Technical Efficacy defined as ablation of the target tumour with the ablation zone completely overlapping or encompassing the entire target tumour assessed using conventional CT imaging.

Secondary outcomes

  1. Procedure Technical Success

    Time frame: Day of procedure

    Procedure technical success defined by the investigator as successful deployment, activation and removal of the ablation catheter according to the investigation plan.

  2. Ablation Technical Success

    Time frame: At Discharge - Day 1

    Ablation technical success defined as the nodule treated according to the investigation plan and covered completely by the ablation zone with an adequate margin assessed using CT imaging.

  3. Safety Assessment - number of device or procedure related Serious Adverse Events

    Time frame: Through to 1 month follow-up

    Number of Serious Adverse events (SAE) related to the device or procedure associated with the use of the FlexAblate System.

  4. Safety Assessment - number of device or procedure related Adverse Events (AE)

    Time frame: Through to 3 months

    Number of Adverse Events (AE) related to the device or procedure.

  5. Quality of Life Assessment - European Organization for Research and Treatment of Cancer Quality of life questionnaire - Cancer (EORTC QLQ-C30)

    Time frame: 12 months

    Patients will rate their responses from 1 to 4 on a Likert Scale (1 being "not at all" and 4 being "very much").

  6. Quality of Life Assessment - EQ-5D-5L health-related quality of life questionnaire

    Time frame: 12 months

    Patients complete the 5 level descriptive system relating to 5 dimensions of health and the EQ visual analogue scale from 0 to 100 (where 0 means the worst health you can imagine and 100 means the best health you can imagine).

  7. Quality of Life Assessment - Bronchoscopic Ablation Patient Pain and Satisfaction Survey

    Time frame: 1 month

    Survey completed by the patient to assess their pain and satisfaction with the ablation procedure.

Other outcomes

  1. Ablation zone size assessment

    Time frame: Discharge - Day 1

    Evaluation of the ablation zone size defined as the radiologic region or zone of induced treatment effect by CT imaging.

  2. Assessment of Local Control

    Time frame: 12 months

    Assessment of target tumour local control defined as local suspicious growth under CT imaging at the originally ablated target tumour within or abutting the ablation zone.

  3. Device user experience

    Time frame: Day of procedure

    Device user experience questionnaire completed at the time of the procedure by the investigator or physician performing the ablation.

  4. Assessment of pulmonary function

    Time frame: 12 months

    Completion of Pulmonary Function Tests to assess pulmonary function.

  5. Ablation ablative margin assessment

    Time frame: Discharge - Day 1

    Evaluation of the size of the ablation margin defined as the ablation beyond the borders of the tumor by CT imaging.
