Lung Cancer Clinical Trial

Tumor Treating Fields (TTFields) Therapy to Manage Brain Metastases in Small Cell Lung Cancer

Summary

This phase II single-arm pilot study will evaluate the safety and preliminary efficacy of Optune-Tumor Treating Fields (TTFields) therapy as a prophylactic approach to reducing small cell lung cancer (SCLC) that has spread to the brain (brain metastases). Optune is a portable battery powered device that produces alternating electrical fields, termed tumor treatment fields ("TTFields") within the human body. These TTFields are applied to the patient by electrically insulated surface transducer arrays, which function to disrupt the rapid cell division of cancer cells.

PRIMARY OBJECTIVE:

I. Observed rate of brain metastases following TTFields therapy at 6 months.

SECONDARY OBJECTIVES:

I. Observed rate of brain metastases following TTFields therapy at 12 months. II. Survival of participants with SCLC after using TTFields therapy. III. Usage and overall safety characteristics of TTFields therapy. IV. Quality of life among participants using TTFields therapy. V. Observed rate of SCLC brain metastases at 6 months from the beginning of the 4th cycle of chemotherapy to development of brain metastases.

OUTLINE:

Participants will receive TTFields therapy on a continuous basis (i.e., 18-24 hours a day, 7 days a week) for a period of 12 months or until the development of brain metastases, whichever comes first. Participants will be able to carry the device in an over-the-shoulder bag or backpack so that they can receive continuous at-home treatment. The investigator or other designated healthcare provider will provide detailed instructions regarding the placement/replacement and positioning of the transducer arrays on the participants head. TTFields are applied to the shaved scalp via two pairs of orthogonally positioned transducer arrays. Each pair of transducer arrays will be centered on the participants shaved head such that one pair is placed on the left and right side of the head, and the second pair placed anteriorly and posteriorly. Transducer arrays should be replaced every 2 to 3 days, with a slight relocation of the new arrays ~2 cm from the prior location.

After completion of study treatment, patients are followed up periodically.

Eligibility Criteria

Inclusion Criteria:

Ability to understand and the willingness to sign a written informed consent document

Pathologically confirmed limited stage (LS)-SCLC or extensive stage (ES)-SCLC

LS-SCLC - stage I-III (Tany, Nany, M0) that can be safely treated with radiation doses. Excludes T3-4 due to multiple nodules that are too extensive of have tumor/nodal volume that is too large to be encompassed in a tolerable radiation plan
ES-SCLC - stage IV (Tany, Nany, M1), or T3-4 due to multiple nodules that are too extensive of have tumor/nodal volume that is too large to be encompassed in a tolerable radiation plan
Must be no more than 6 weeks from having received last dose of chemo- and/or radiotherapy for primary tumor to anticipated start of TTField therapy
Partial response to standard of care (chemo- and/or radiotherapy) as judged by treating physicians with no evidence of recurrence as observed by thoracoabdominal computed tomography (CT) within 12 weeks of enrollment
No brain metastases as observed by gadolinium (gd)-magnetic resonance imaging (MRI) within 12 weeks of enrollment
No previous or currently active second malignancy, with exception of non-metastatic prostate cancer, treated stage I breast cancer, skin malignancies
Life expectancy of at >= 3 months
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60)
Participants must be willing and able to fully comply with the minimum required 18 hours/day of TTField therapy
Women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation

Exclusion Criteria:

Malignant disease, other than that being treated in this study, with exception of non-metastatic prostate cancer, treated stage I breast cancer, skin malignancies
Implanted pacemaker, defibrillator or deep brain stimulator, or documented clinically significant arrhythmias

Active implanted medical device (e.g. deep brain stimulators, spinal cord stimulators, vagus nerve stimulators, pacemakers, defibrillators, and programmable shunts)

External medical devices (e.g., insulin pumps) are permitted
Skull defect (e.g. missing bone with no replacement)
Shunt
Bullet fragments
Evidence of increased intracranial pressure (midline shift > 5 mm, clinically significant papilledema, vomiting and nausea or reduced level of consciousness)
Sensitivity to conductive hydrogels
Pregnant or lactating women
Underlying serious skin condition on the scalp, which in the opinion of the investigator, would prevent or interfere with TTField therapy
Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of participant safety or study results
