This clinical trial tests the effectiveness of the AveCure flexible microwave ablation probe using cone beam computed tomography (CBCT)-guided robotic assisted bronchoscopic microwave ablation (MWA) to destroy cancerous lung nodules up to 3 cm in size in patients with lung cancer. Computed tomography (CT) images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient’s body. AveCure microwave ablation uses a directed electromagnetic wave to deliver a high-frequency, electric current to kill cancer cells by heating them. This trial may help determine whether AveCure flexible microwave ablation probe can be used bronchoscopically to help destroy target cancerous lung nodules that are up to 3 cm in size prior to surgery.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT05281237.
PRIMARY OBJECTIVES:
I. Determine the safety and feasibility of the AveCure 16 gauge flexible microwave ablation probe (AveCure 16G-FMAP) to ablate a target dominant nodule in surgically resectable lung cancer.
Ia. Feasibility of performing the procedure as planned in enrolled subjects (as defined by intraoperative pathologic confirmation of malignancy; CBCT confirmation of microwave probe centered in lesion, and completion of microwave treatment);
Ib. Feasibility of ablation will be defined as radiologic and/or pathologic evidence of ablation effect as evaluated on post-ablation CT imaging and standard of care pathologic evaluation of lung resection specimens;
Ic. Safety as defined by subject tolerance of the procedure as well as intraoperative and postoperative monitoring for complications including but not limited to hemoptysis, pneumothorax, pleural effusion, infection, post-ablation syndrome, and inability to subsequently have standard of care surgical resection as planned.
SECONDARY OBJECTIVES:
I. Further histologic evaluation of microwave ablation zone:
Ia. Size of ablation zone;
Ib. Size/proportion of viable cancer tissue;
Ic. Local tissue effects surrounding ablation zone.
II. Further radiologic evaluation of microwave ablation zone:
IIa. Size of presumed ablation zone per post-ablation CT imaging;
IIb. Dimensions and orientation of presumed ablation zone relative to intraoperative microwave catheter orientation.
III. Comparison of estimated radiologic ablation zone vs. histologic ablation zone on gross pathology.
IV. Comparison of pre-procedure planned ablation zone per microwave settings versus (vs.) actual ablation zone of resected pathology.
V. Evaluation of the radiologic progression of the ablation zone (comparison of immediate post-ablation CBCT vs CT obtained 1-4 weeks following ablation).
OUTLINE:
Patients undergo CBCT-guided robotic assisted bronchoscopic MWA. Patients then undergo follow-up chest high resolution CT scan (HRCT) and undergo surgery 2–6 weeks after the MWA procedure. Additionally, patients undergo chest X-ray throughout the study.
After completion of study treatment, patients are followed for up to 6 months after surgery.
