Study type
Description of intervention(s) / exposure
Thermal Vapor Ablation delivered to target lung areas (Cancerous Lesions). Thermal Vapor Ablation involves the delivery of a measured dose boiling water to the area surrounding the cancerous lesion.
The Vapor ablation will be delivered by an interventional pulmonologist (respiratory physician) in a bronchoscopy suite within a hospital.
One dose of 330 calories of energy is delivered to targeted lung lesions (according to a CT guided therapy plan) during a single bronchoscopic procedure prior to lung resection. This procedure will generally take less than 30 minutes to perform.
Lung resection will then occur according to the standard hospital procedures.
Subjects will be treated with Thermal Vapor Ablation (BTVA-C) and the interval between ablation and resection will be a minimum of 60 hours to a maximum of 105 hours, with the exact scheduling determined by the investigator.

Safety will be evaluated as the 30-day (or date of Day 30 follow-up) number of reported adverse events (AEs), serious adverse events (SAEs) related to the BTVA-C procedure.
Possible or known adverse events associated with the investigational device / procedure may include:
The possible risks associated with bronchoscopy:
Very Common (>50%)
- none
Common (between 10% and 50%)
- Sore throat
- Injury to teeth
- Bleeding

Uncommon (between 1% and 10%)
- Asthma-like reaction
- Fever

Rare (<1%)
- Infection (higher risk for smokers)
- Thrombosis (blood clot) in legs
- Pneumothorax
- Myocardial infarction (heart attack)
- Pulmonary enema
- Cardiac arrest
- Spasm of the muscles in your airway and / or voice box
- Death

The possible risks of the BTVA-C treatment:

- Bronchitis or pneumonitis (airway inflammation)
- Cough
- Minor bleeding
- Pain at the treatment site
- Respiratory distress

Uncommon (between 1% and 10%)
- Fever o Fatigue
- Loss of appetite
- Pneumonia
- Damage to lung lobes, chest wall or heart
- Pleural effusion (fluid between chest wall and lungs)

These possible adverse events will be evaluated by observation following the Vapor Ablation Procedure. CT Scans may be used to evaluate the impact of the Vapor Ablation on lung tissue if determined as required by the investigator.

Timepoint [1] 307837 0
30 days post BTVA-C procedure
Secondary outcome [1] 353091 0
Feasibility will be evaluated by assessing the ability of the BTVA-C System to achieve successful delivery of the thermal vapor ablation treatment according to the Instructions for Use (IFU) and navigation plan.
• Histological evidence of ablation using a tetrazolium based tissue viability stain to assess the extent and characteristics of the primary mechanism of thermal vapor ablation as well as secondary mechanisms (ischemia, nutrient depletion, apoptosis, necroptosis, etc.) in relation to the tumor focus.
• CT imaging, between ablation and resection procedures, to identify ischemic tissue within the treatment areas.
Timepoint [1] 353091 0
During and at the completion of the BTVA-C Procedure

Brief summary
The purpose of this study is to examine the feasibility and safety of a device for ablating cancerous lung tumors using a technique called thermal vapor ablation.

Who is it for?
You may be eligible for this study if you are aged 18 or older and are a suitable candidate for resection of a lung cancer tumor.

Study details
All participants will receive one treatment of thermal vapor ablation via a bronchoscope (tube down the throat), 2-4 days before undergoing their scheduled surgical lung resection. The treatment takes place under general anaesthetic in a day surgery procedure area. All participants will be followed-up using standard hospital procedures.

It is hoped that this research will provide information into the non-surgical treatments of lung cancer, thereby providing future non-surgery related options for the disease.
