Study type
Description of intervention(s) / exposure
Radiofrequency Ablation delivered to target lung areas (Cancerous Lesions). Radiofrequency Ablation involves the delivery of a measured dose of radiofrequency energy to the area surrounding the cancerous lesion.
The radiofrequency ablation will be delivered by an interventional pulmonologist (respiratory physician) in a bronchoscopy suite within a hospital.
Dose(s) of up to 80 watts 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 60 minutes to perform.
Lung resection will then occur according to the standard hospital procedures.
Subjects will be treated with Radiofrequency ablation and the interval between ablation and resection will be a minimum of 48 hours to a maximum of 2 weeks, with the exact scheduling determined by the investigator.

The possible risks of the Radiofrequency Ablation treatment:

- Very Common (>50%) - None.

Secondary outcome [1] 377139 0
Feasibility will be evaluated by assessing the ability of the Zidan Medical RFA System to achieve the following:

- Successful delivery of the radiofrequency ablation treatment according to the IFU and treatment plan.
- Histological evidence of ablation using a H&E tissue viability stain to assess the extent of the coagulative necrotic zone in relation to the tumor focus, as well as zones of temporary inflammation and edema.
- CT imaging, between ablation and resection procedures, to identify the extent of treatment areas.
Timepoint [1] 377139 0
During and at the completion of the BTVA-C Procedure

Can healthy volunteers participate?
Key exclusion criteria
1. The following lesions should be excluded from the study for safety reasons:

b. Tumors less than 1cm from any pleural surface
c. Tumours that do not have normal lung clearance of less than 1cm around the target lesion.
d. Tumours that are less than 2cm from major pulmonary artery vasculature (as assessed by CT)
2. Carcinoid lung tumors
3. Tumor is associated with atelectasis or obstructive pneumonitis or pleural effusion
4. Pulmonary function tests (PFTs): post-bronchodilator forced expired volume in one second (FEV1) or forced vital capacity (FVC) < 50% predicted, diffusing capacity of the lung for carbon monoxide (DLCO) <50% predicted

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 radiofrequency 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 radiofrequency ablation via a bronchoscope (tube down the throat), 2-14 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.
