Clinical Trial Summary

This study is a prospective, single-arm, multi-center, pilot trial of Bronchoscopic Thermal Vapor Ablation for Lung Cancer (BTVA-C) in patients with primary lung cancer or metastatic cancer in the lung. Patients who have consented to participate in this study (enrolled) will be subject to eligibility screening and baseline assessments, prior to undergoing the BTVA-C procedure. Only patients that meet all of the inclusion criteria and none of the exclusion criteria will receive vapor ablation treatment.

Patients will be followed for up to 12 months.

Description:

This study is a prospective, single-arm, multi-center, pilot trial of Bronchoscopic Thermal Vapor Ablation for Lung Cancer (BTVA-C) in patients with primary lung cancer or metastatic cancer in the lung.

Subjects identified for this study will be those that have microscopic proof of malignancy. Patients who have consented to participate in this study (enrolled) will undergo screening assessments to evaluate the inclusion criteria associated with their lung cancer and general health. Only patients that meet all of the inclusion criteria and none of the exclusion criteria will be scheduled for treatment with the BTAV-C System.

A total of 10 subjects will be treated at up to 3 investigational sites within the EU.

Prior to the vapor ablation procedure, the patient's CT scan is analyzed to evaluate the location and size of the target lesion. The segments and airways associated with the lesion are identified and images are created to aid in the navigation to appropriate treatment locations during the upcoming procedure.

At the time of the vapor ablation procedure, the Uptake catheter is placed in a selected airway with a thin bronchoscope. A balloon at the distal end of the catheter is then inflated to occlude the bronchus prior to vapor infusion. Sterile water is heated to approximately 100° - 140°C by a reusable generator and vapor (steam) is infused into the targeted region for 8 seconds at a precisely controlled flow rate and power. If necessary, the catheter is moved to the next airway and the procedure is repeated until all desired airways have been treated (maximum 3 treatments). The treatment creates a uniform field of necrosis in the parenchyma around the lesion.

Patients will be evaluated for clinical symptoms in the 30-day period following ablation. Local control of the tumor will be evaluated based on Response Evaluation Criteria in Solid Tumors (RECIST) from low dose CT scans at 1, 3, 6 and 12 months following ablation.
