Pre-operative Tumor Treating Fields in Patients With Resectable Lung Cancer

February 19, 2026 updated by: John Waters, University of Texas Southwestern Medical Center

Phase 0 Trial of Pre-operative Tumor Treating Fields in Patients With Resectable Lung Cancer

The purpose of this study is to study the clinical and biologic effects of Tumor Treatment Fields (TTFields) in patients undergoing resection of stage I-IIIA Non-Small Cell Lung Cancer (NSCLC). TTField is a non-invasive treatment that uses low-intensity electrical fields to treat cancer. Resection is the medical term for surgically removing part or all of a tissue, structure, or organ.

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

To study the clinical and biologic effects of Tumor Treatment Fields (TTFields) in patients undergoing resection of stage I-IIIA NSCLC.

Participants in this study will have a blood sample collected as well as vital signs along with a tumor tissue sample and tumor scan. Once it has been determined the participant can enroll into this study, he/she will come to the clinic for 5 scheduled visits over a period of 2 months .

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Diagnosis of stage I-IIIA NSCLC planned for surgical resection.
  2. Eastern Cooperative Oncology Group (ECOG) 0-2 performance status.
  3. Willingness and ability to undergo planned correlative studies, including imaging tests.
  4. Fresh biopsy diagnostic material obtained from standard of care procedure to perform baseline correlatives (10-15 slides)-if not available, enrollment will be considered on a case-by-case basis after discussion with and approval by the Lead Site PI or Lead Site Co-Principal Investigator.
  5. Ability to understand and the willingness to sign a written informed consent.

  6. All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

    • 6a. A female of child-bearing potential is any woman (regardless of sexual orientation, marital status, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
    • • Has not undergone a hysterectomy or bilateral oophorectomy; or
    • • Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
  7. Age ≥22 years at time of screening.

Exclusion Criteria:

  1. Receipt of prior therapy for the current NSCLC.
  2. Planned neoadjuvant therapy for the current NSCLC.
  3. History of major allergic reactions attributed to adhesive or compounds in TTFields micro-array.
  4. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements.
  5. Pregnant or nursing patients due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
  6. Use of electronic devices or prosthetics - i.e., pacemakers, defibrillators, spinal infusion pumps. Specific scenarios can be discussed with the Lead Site PI or Lead Site Co-Principal Investigator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Effect of TTF (Tumor-Treating Fields) on Fanconi anemia-related genes.
Time Frame: approximately 14-28 days
Determine the effect of TTFields on expression of Fanconi anemia pathway-associated genes in NSCLC.
approximately 14-28 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety of administering TTFields
Time Frame: approximately 14-28 days

Assess the safety of administering TTFields prior to standard of care lung cancer resection.

Analyses will be performed for all subjects having initiated TTFields therapy. The study will use the CTCAE version 5.0 for reporting of adverse events.
