Microwave Ablation

Brief summary

Patients with medically inoperable and operable secondary soft tissue lesion(s) of the lung will have transbronchial microwave ablation performed using cone beam CT for probe guidance and confirmation.

Detailed description

Adult patients with medically inoperable and operable secondary soft tissue lesion(s) of the lung less than 2cm will undergo transbronchial microwave ablation performed by an interventional pulmonologist or thoracic surgeon using cone beam CT imaging for probe guidance and confirmation on ablation outcome. All treated patients will be followed for one year following the ablation procedure for efficacy and safety.

Interventions

DEVICEMicrowave ablation

Microwave ablations will be performed under general anesthesia via a transbronchial approach by an interventional pulmonologist or thoracic surgeon. Prior to the ablation, the treating physician will perform an endobronchial ultrasound (EBUS) to confirm disease staging.

Inclusion criteria

1. Signed Informed Consent 2. Patients greater or equal to 18 years of age 3. Performance status 0-2 (Eastern Cooperative Oncology Group classification \[ECOG\]) 4. Willing to fulfill all follow-up visit requirements 5. Medically inoperable and operable secondary soft tissue lesion(s) of the lung 6. A maximum of two ipsilateral soft tissue lesions less than or equal to 2cm in the outer two-thirds of the lung and not closer than 1cm to the pleura. Lesion size must be measured with at least 2-dimensional imaging.

Exclusion criteria

1. Scheduled concurrent procedure for the target soft tissue lesion(s) 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 coagulopathy at the time of screening 5. Patient with implantable devices, including pacemakers or other electronic implants 6. Prior pneumonectomy or bronchiectasis 7. Severe neuromuscular disease 8. Patient count less than or equal to 50,000/mm cubed 9. ASA (American Society of Anesthesiologists) score of greater than or equal to 4 10. Inability to tolerate anesthesia 11. Expected survival less than 6 months 12. Clinically significant hypertension 13. Chronic, continuous ventilator support, which uses bi-level positive airway pressure (PAP) to improve lung function for severe conditions (however, intermittent PAP, for non-pulmonary conditions, such as sleep apnea, is permitted) 14. Endobronchial soft tissue lesions proximal to the segmental airways 15. Imaging findings of active pulmonary infection 16. The patient was judged unsuitable for study participation by the Investigator for any other reason.

Design outcomes

Primary

MeasureTime frameDescription
Device User Experience SurveyDay of ablation (day 0)The Device User Experience Survey is an unvalidated, Sponsor-generated questionnaire aimed to increase the Sponsor's understanding of the usability of the NEUWAVE microwave ablation system. The questionnaire asks approximately 30 questions (includes yes/no responses, rating scales, and fill-in-the-blank sections) and is to be completed by the treating physician at the completion of each ablation. A summary of all treating physician responses will be generated at the completion of the study to summarize the overall user experience with the device.
Technical Success (lesion completely ablated)Day of ablation (day 0)Technical Success is determined by the treating physician and is defined as the ablation zone completely overlapping or encompassing the target lesion plus an ablative margin, as assessed by cone beam CT imaging, immediately following the ablation procedure.
Technique Efficacy (lesion completely ablated)30 days post-ablationTechnique Efficacy is determined by the treating physician and is defined as the ablation zone completely overlapping or encompassing the target lesion plus an ablative margin, as assessed by cone beam CT imaging, at Visit 3 (i.e. 30 days post-ablation).

Secondary

MeasureTime frameDescription
Secondary Efficacy Rate1 year post-ablationThe Secondary Efficacy Rate is defined as the percentage of soft tissue lesions that have undergone successful repeat ablations following identification of local soft tissue lesions progression, as assessed using CT imaging by the treating physician throughout the entirety of the study (i.e. 1 year post-ablation).
Length of Hospital StayDay of ablation (day 0)The Length of Hospital Stay is defined as the length of time of hospitalization from the end of the ablation procedure to the time of discharge (up to 23 hours post-ablation).
Hospital Readmission Rate30 days post-ablationThe Hospital Readmission Rate is defined as the percentage of patients who were readmitted to the hospital within 30 days of the ablation procedure.
Target Lesion Recurrence1 year post-ablationTarget Lesion Recurrence is defined as the reappearance of the lesion(s) at the treated site, as assessed using CT imaging by the treating physician throughout the entirety of the study (i.e. through 1 year post-ablation).
Adverse Events1 year post-ablationAny AEs attributable to the ablation procedure, including all device-related, procedure-related, and SAEs, evaluated from the start of the ablation procedure throughout the entirety of the study (i.e. through 1 year post-ablation).
Primary Efficacy RateDay of ablation (day 0)The Primary Efficacy Rate is the percentage of target lesions successfully eradicated following the first ablation procedure, as assessed using CT imaging by the treating physician on the day of ablation.

Other

MeasureTime frameDescription
EORTC QLQ-C301 year post-ablationThe EORTC (European Organization for Research and Treatment of Cancer) QLQ-C30 is a quality of life questionnaire with 30 questions aimed specifically for cancer patients. Patients will complete this questionnaire at each study visit.
Numeric Pain Scale30 days post-ablationThe Numeric Pain Scale is a questionnaire where the patient reports their pain on a scale from 0-10 (where 0 is 'no pain' and 10 is 'maximum pain). Patients will complete this questionnaire at each study visit through 30 days post-ablation.
EORTC QLQ-LC131 year post-ablationThe EORTC (European Organization for Research and Treatment of Cancer) QLQ-C30 is a quality of life questionnaire with 13 questions aimed specifically for lung cancer patients. The questionnaire asks patients to rate their responses on a scale from 1-4 (1 being not at all and 4 being very much). Patients will complete this questionnaire at each study visit.
