Study summary

The feasibility of a RF ablation catheter to bronchoscopically ablate lung tumors, will be evaluated in patients already scheduled for surgical resection.

Read the detailed description

This study is a prospective, single-arm, single-center, pilot study of bronchoscopic Radio-Frequency Ablation (RFA) treatment of target lung lesions, prior to surgical tumor resection. Up to ten (10) subjects will be treated at the investigational site.

Subjects identified for this study will be those that have a surgical resection already scheduled as part of their lung cancer treatment. Patients who have consented to participate in this study (enrolled) will undergo screening assessments to evaluate the inclusion criteria associated with their lung cancer and general health. Only patients that meet all of the inclusion criteria and none of the exclusion criteria will be scheduled for RFA treatment.

Prior to RFA, high-resolution computed tomography (HRCT) scans will be used to characterize the lesion and determine the access pathways for ablation. At the time of the RFA procedure, a point-of-entry, along a bronchial wall, is created under an image-guided navigation system. The RFA catheter is advanced down the access path until it reaches the tumor and RF is administered at the prescribed dose. Upon completion of the RFA treatment, the subject is immediately prepared for surgical resection in accordance with their lung cancer standard of care. There are no follow-up visits as part of this study, the subject is excited following surgical resection.

The resected tissue will undergo pathological evaluation for tissue viability.

Inclusion criteria

  • Proven NSCLC or pulmonary metastases from extra-thoracic primary tumor
  • Must be eligible for curative lung resection (lobectomy)

Exclusion criteria

Exclusion Criteria:

  • Any contraindication to bronchoscopy, for example:

    • Untreatable life-threatening arrhythmias.
    • Inability to adequately oxygenate the patient during the procedure.
    • Acute respiratory failure with hypercapnia (unless the patient is intubated and ventilated).

  • Known coagulopathy
  • Platelet dysfunction or platelet count \<100 x 10\^3 cells/mm3
  • History of major bleeding with bronchoscopy
  • Suspected pulmonary hypertension: additional testing required, such as ECG
  • Moderate-to-severe pulmonary fibrosis
  • Severe emphysema (GOLD III/IV) or chronic obstructive pulmonary disease (COPD):

additional testing and PI consent is required

  • Bullae >5cm located within the same lobe of target tumor/lesion
  • Any other severe or life-threatening comorbidity that could increase the risk associated with bronchoscopic RFA
  • Ongoing systemic infection
  • Contraindications to general anesthesia
  • Inability to stop anticoagulants or antiplatelet agents prior to procedure as dictated by the protocol
  • Prior thoracic surgery on the same side of the lung as the targeted tumor/lesion
  • Breastfeeding women or females of childbearing potential with a positive pregnancy test prior to the procedure or the intent to become pregnant during the study
  • Life expectancy of less than one year.
