Post-Market Optimization Study of the EMPOWER® RF Catheter to Ablate Soft Tissue Lesions in the Lung

• Conditions: Lung Diseases
• Interventions: Device: Radiofrequency (RF) catheter

• Registration Number: NCT04131777
• Lead Sponsor: Broncus Medical Inc

Brief Summary

A post-market study to assess the performance and safety of a RF ablation catheter to bronchoscopically ablate lung lesions will be evaluated in patients with confirmed diagnosis of non-small cell lung cancer or metastatic lung lesions who are scheduled for surgical resection.

Detailed Description

This study is a prospective, single-arm, multi-center, post-market study of bronchoscopic radio frequency (RF) ablation treatment malignant lung lesions prior to surgical resection. Up to 15 patients will be treated at the participating sites.

Patients identified for the study will have been scheduled for surgical resection as part of their treatment for lung lesions. The RF ablation procedure will be performed during a standard-of-care bronchoscopic procedure at minimum of 24 hours prior to resection. The patients exits the study following surgical resection. The resected tissue will undergo pathological evaluation for tissue viability.

Arm && Interventions

Group	Intervention	Description
Optimized	Radiofrequency (RF) catheter	Patients treated using optimal RF algorithm
Roll-in	Radiofrequency (RF) catheter	Initial patients enrolled until optimal RF algorithm is determined

Primary Outcome Measures

Name	Time	Method
Performance - maximum diameter of zone of thermal necrosis surrounding treated lesion	The interval between ablation and tissue resection for pathological analysis is a minimum of 24 hours, but the exact interval depends on the investigator's standard of care	Maximum diameter (in mm) of ablation zone (thermal necrosis) surrounding treated lesion as measured in resected tissue by quantitative histopathological and gross pathological analysis
Performance - ability of the user and device to deliver ablative treatment in accordance with the catheter's Instructions for Use	Assessed at the time of the RF ablation procedure	The ability of the ablation treatment to be delivered as per the Instructions for Use will be assessed using a binary categorical scale (yes/no)
Safety - Adverse events (AEs) and serious adverse events (SAEs)	AEs and SAEs related to the RF procedure/device will be reported for the interval beginning with the RF ablation procedure and ending with the surgical resection of the ablated lung tissueion	The incidence of reported adverse events and serious adverse events related to the RF ablation procedure/device
