Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

Is microwave ablation generally safe for treating lung cancer?

Studies have shown that microwave ablation is generally safe for treating lung cancer, with research indicating its feasibility and safety in both human and animal models. ^{1 2 3 4 5}

How is the AveCure Flexible Microwave Ablation Probe treatment different from other lung cancer treatments?

The AveCure Flexible Microwave Ablation Probe is unique because it uses a flexible catheter to deliver microwave energy directly to lung tumors, offering a minimally invasive option for patients who cannot undergo surgery. This treatment can create larger ablation zones more quickly than traditional methods like radiofrequency ablation, and it does not require grounding pads, making it potentially more effective and convenient. ^{2 3 5 6 7}

What is the purpose of this trial?

This research study to determine the effectiveness of the AveCure Flexible Microwave Ablation Probe to destroy cancerous lung nodules up to 3 c m in size. This research study involves microwave ablation (MWA)

Eligibility Criteria

This trial is for adults over 22 with Stage I-II primary lung cancer, specifically solitary nodules up to 3 cm. They must have a confirmed type of malignancy and be candidates for surgery. Excluded are those with nodules under 1 cm, prior treatments on the nodule, contraindications to bronchoscopy, significant comorbidities, electronic implants, coagulopathy issues or participation in other lung cancer studies.

Inclusion Criteria

My tumor can be reached and checked with a special lung biopsy technique.

I am 22 years old or older and can give my consent.

You need to have a biopsy that shows the type of tumor you have, and it needs to be a good sample for testing.

Exclusion Criteria

My targeted tumor has been treated with radiation or chemotherapy before surgery.

I have a blood clotting disorder.

I cannot undergo a flexible bronchoscopy due to health reasons.

Treatment Details

Interventions

• AveCure Flexible Microwave Ablation Probe

Trial Overview The study tests the effectiveness of the AveCure Flexible Microwave Ablation Probe on destroying cancerous lung nodules up to 3 cm. It involves microwave ablation (MWA) using this probe through navigational bronchoscopy and cone beam CT scan confirmation during operation.

Participant Groups

Group I: AVECURE FLEXIBLE MICROWAVE ABLATION PROBE FOR LUNG NODULES Experimental Treatment 1 Intervention

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. * Ablation Procedure- MWA will be used to treat solitary pulmonary nodules up to 3cm. * CT scan will then be performed to evaluate the radiological changes 2 - 4 weeks after the ablation procedure. * Surgery will be performed to remove the lung nodule and the tissue will be evaluated by pathology.

AveCure Flexible Microwave Ablation Probe is already approved in United States for the following indications:

Approved in United States as AveCure Flexible Microwave Ablation Probe for:

• Palliative treatment in spinal procedures by ablation of metastatic malignant lesions in a vertebral body
• Coagulation and ablation of tissue in bone during surgical procedures
• Treatment of cancerous lung nodules up to 3 cm in size

Findings from Research

Microwave ablation is a safe and effective treatment for lung tumors, with a median time to tumor recurrence of 62 months and lower recurrence rates for tumors smaller than 3 cm.

The study found that larger tumors (greater than 3 cm) had higher odds of treatment failure and complications, highlighting the importance of tumor size in the success of microwave ablation.

Microwave Ablation for Lung Neoplasms: A Retrospective Analysis of Long-Term Results. Healey, TT., March, BT., Baird, G., et al.[2022]

In a pilot study involving 13 patients with inoperable peripheral lung cancer, endobronchial microwave ablation using navigation bronchoscopy achieved a technical success rate of 100%, indicating that the procedure is feasible and can be performed effectively.

The treatment resulted in a complete ablation rate of 78.6% and a 2-year local control rate of 71.4%, with a median progression-free survival of 33 months, suggesting that this method can provide significant therapeutic benefits for patients who are not candidates for surgery.

Microwave ablation via a flexible catheter for the treatment of nonsurgical peripheral lung cancer: A pilot study. Xie, F., Chen, J., Jiang, Y., et al.[2022]

The use of a novel three-dimensional visualization ablation planning system (3D-VAPS) in microwave ablation (MWA) for stage I non-small cell lung cancer (NSCLC) resulted in a 100% technical success rate and a 97.35% complete ablation rate three months post-procedure, indicating high efficacy.

The study reported no deaths during or within 30 days after the MWA procedure, and while complications such as pneumothorax and intrapulmonary hemorrhage occurred, the overall safety profile was deemed acceptable, suggesting that 3D-VAPS can help optimize the procedure and reduce risks.

The safety and feasibility of three-dimensional visualization planning system for CT-guided microwave ablation of stage I NSCLC (diameter ≤2.5 cm): A pilot study. Hu, Y., Xue, G., Liang, X., et al.[2023]

In a study of 231 patients with early-stage non-small cell lung cancer (NSCLC), those with tumors near bronchovascular bundles had lower local progression-free survival rates, indicating that tumor location significantly impacts treatment outcomes.

Achieving a specific ablation range during CT-guided microwave ablation may enhance local efficacy for tumors adjacent to bronchovascular bundles, potentially improving patient outcomes.

The study demonstrated that flexible bronchoscopy-guided water-cooled microwave ablation (MWA) is both feasible and safe for treating peripheral lung cancer in porcine models, with no complications reported during the procedures.

Ablation successfully created coagulation necrosis in lung tissue, indicating effective treatment, and showed signs of tissue repair after 4 weeks, suggesting potential for MWA as a therapeutic option for lung cancer.

Microwave ablation is emerging as a promising treatment for unresectable lung cancer, offering potential advantages over radiofrequency ablation, such as larger ablation zones and shorter heating times.

The study highlights a complication of microwave ablation, specifically bronchocutaneous fistula (BCF), and discusses various treatment options for BCF, emphasizing the importance of understanding device limitations as microwave ablation becomes more widely used.

In a study of 66 patients with advanced lung cancer, combining microwave ablation (MWA) with systemic treatment significantly improved the overall response rate (ORR) to 63.6%, compared to 24.4% in the control group receiving only systemic treatment.

The combination therapy was safe, with only mild adverse events reported, and it resulted in longer progression-free survival (PFS) and overall survival (OS) times, indicating a lower risk of disease progression and death.
