About

The overall purpose of this study is to characterise the clinical safety and performance of the Creo Medical MicroBlate™ Flex AB1 instrument in patients with pathologically confirmed malignancy eligible for surgical resection of their nodule, receiving bronchoscopic ablation prior to surgery.

Full description

This is a post-market, prospective, single-arm, multicentre, open-label, non-randomised study which will enrol up to 30 subjects in total (plus replacements if required due to drop out).

Prospective patients must have a histopathological-confirmed malignant lung lesion and be candidates for surgical resection. After being informed about the study and potential risks, all patients giving their written informed consent will undergo a screening visit to determine eligibility for study entry.

The study consists of two (2) stages (Stage A and Stage B). Stage A consists of the ablation and surgical resection being performed concurrently on Day 0 within a single procedure. Stage B consists of the ablation and the surgical resection being performed in separate procedures. The surgical resection will occur between Day 7 and Day 21, post-ablation, inclusive of those days. The aim is to follow local guidelines for treatment of lung cancer.

Patients undergoing Stage A will be released from the study at point of standard of care discharge from hospital post-surgery and will not be followed as part of the study (patients will receive SoC follow-up and care post release from study).

Patients undergoing Stage B will have evaluations at follow-up visits conducted at 7 (+/-3) days (via phone call) post ablation and prior to the surgical resection procedure. Stage B patients will be released from the study at point of standard of care discharge from hospital post-surgery and will not be followed as part of the study (patients will receive SoC follow-up and care post release from study).

Inclusion criteria

Patients who:

Have signed informed consent.
Subject is willing and able to comply with all aspects of the treatment and evaluation schedule.
Are ≥ 18 years old.
Have lung lesion(s)/nodule(s) which are histopathological-confirmed as cancer.
Have soft tissue lung lesion(s):
- ≤ 30 mm in the largest dimension of the pulmonary window for Stage A.
- ≤ 20 mm in the largest dimension of the pulmonary window for Stage B.

Subject is willing and able to comply with the study protocol requirements.
Are assigned an ASA (American Society of Anaesthesiologists) score of ≤ 3 or the patient is deemed fit for general anaesthesia.

Exclusion criteria

Patients who:

Are pregnant or breast feeding, as determined by standard site practices.
Have participated in an investigational drug or device research study within 30 days of enrolment that would interfere with this study.
Have a physical or psychological condition that would impair study participation or jeopardise the safety or welfare of the subject.

Have known pulmonary hypertension (PASP [pulmonary artery systolic pressure] >50mmHg).
Who are currently prescribed anticoagulants, clopidogrel or other platelet aggregation inhibitors which can´t be stopped or temporarily withheld.
Subject had a prior pneumonectomy.
Diagnosis of Small Cell Lung Cancer.
Any patient with clinically significant interstitial lung disease in the zone of planned ablation.
Subject had a therapeutic intervention (e.g., SBRT) within same lobe as the target lesion.
Subjects currently undergoing or underwent chemotherapy, systemic immunosuppressive treatment, or radiotherapy within 3 months of planned Study procedure.
