AveCure Flexible Microwave Ablation Probe for Peripheral Lung Nodule
Trial Status: active
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.
Inclusion Criteria
Subject with primary, treatment naïve, lung cancer (dominant nodule up to 3 cm) with diagnosis confirmed on previous pathology, intraoperative rapid on-site evaluation (ROSE), or intraoperative frozen section pathology.
* Dominant nodule will be defined as the only nodule on the CT for which therapeutic intervention is thought indicated by the multidisciplinary team.
* Non-dominant nodule(s) will be defined as any separate lung nodule(s) that are smaller than the dominant lung nodule and for which plan of the multi-disciplinary team plan is for further monitoring with CT chest rather than therapeutic intervention
Target nodule/tumor which can be accessed via robotic bronchoscopy and confirmed location with cone beam CT scan intra-operatively
Candidate for surgical resection as evaluated by a thoracic surgeon involved in their clinical care. While wedge resection is acceptable, all patients should be deemed candidates for lobar resection if needed
* Surgical candidates will be defined as:
** Patients who otherwise have adequate cardiopulmonary status to undergo lung respective surgery as evaluated by a thoracic surgeon involved in their clinical care.
*** Standard of care pulmonary functions test will be obtained prior to bronchoscopy as deemed necessary by treating surgeon.
** Patients without evidence of N2/N3 or metastatic disease, as upfront surgery would not typically be offered to such patient as part of their cancer-directed care.
*** The absence of N2/N3 disease or metastatic disease will be confirmed by review of pre-operative positron emission tomography (PET)-CT and/or magnetic resonance imaging (MRI)s obtained as part of standard of care radiographic staging evaluation.
*** The absence of N2/N3 disease will additionally be confirmed with clinically indicated minimally invasive mediastinal staging (e.g. endobronchial ultrasound bronchoscopy [EBUS]) which may be performed under the same general anesthesia session prior to the microwave ablation treatment.
Participants must be at least 22 years old and able to provide consent
Tumor is >= 1 cm from the central bronchial tree (distal 2 cm of the trachea, carina, and named major lobar bronchi up to their first bifurcation)
Lung lesion is not contiguous with and >= 0.5 cm from the pleura/fissures
Exclusion Criteria
Subjects in whom flexible bronchoscopy is contraindicated
Any comorbidity that the investigator feels would interfere with the safety of the subject or the evaluation of study objectives
Pacemaker, implantable cardioverter, or another electronic implantable device
Patients with increased bleeding risk (e.g. prothrombin time [PT]/international normalized ratio [INR] > 1.5, platelets [PLTS] < 150 K, uninterruptable anticoagulation, uninterruptable dual antiplatelet therapy)
Patients in other therapeutic lung cancer studies
Subject is pregnant or breastfeeding
Coronavirus disease 2019 (COVID-19) positive patient at the time of procedure

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 patients (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 patient 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– 4 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.
