Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
