Tumor-Treating Fields Therapy in Preventing Brain Tumors in Participants With Extensive-Stage Small Cell Lung Cancer

PRIMARY OBJECTIVES:

I. To measure the feasibility and compliance of NovoTTF-200A as prophylactic cranial tumor
treatment fields (TTF) therapy, determined by percent (%) of patients continuing TTF therapy
until intracranial tumor progression, discontinuation due to dose limiting toxicity (DLT), or
6 months.

SECONDARY OBJECTIVES:

I. To evaluate time to intracranial failure after NovoTTF-200A. II. To evaluate overall
survival after NovoTTF-200A. III. To evaluate the rates of intracranial failure at 2, 4, 6,
8, 10, 12 months after NovoTTF-200A.

IV. To evaluate intracranial failure free survival after NovoTTF-200A. V. To evaluate the
rate of decline in Hopkins Verbal Language Test-Revised (HVLT-R) free recall, delayed recall
and delayed recognition, Controlled Oral Word Association Test (COWAT) and Trail Making Test
(TMT) Parts A and B at 2, 4, 6, 8, 10, 12 months after NovoTTF-200A.

VI. To evaluate time to neurocognitive failure after NovoTTF-200A. VII. To evaluate
neurocognitive failure-free survival after NovoTTF-200A. VIII. To evaluate quality of life
using the European Organization for Research and Treatment of Cancer Quality of Life
Questionnaire Core 30 (EORTC Quality of life Questionnaire C30) with BN20 addendum after
NovoTTF-200A.

IX. To assess adverse events, severity, and frequency associated with NovoTTF-200A using the
Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

OUTLINE:

Participants undergo tumor-treating fields therapy using the NovoTTF-200A device over 18
hours per day for a minimum of 4 weeks and up to 1 year in the absence of disease
progression, unacceptable toxicity, or intracranial failure.

After completion of study treatment, participants are followed up at 8 weeks.

Inclusion Criteria:

- Life expectancy of > 3 months

- Histologically proven extensive stage small cell lung carcinoma (ES-SCLC) (any T any N
and any M stage) within 6 months prior to start of study treatment with the
NovoTTF-200A, with a partial or complete response to at least four cycles of
first-line chemotherapy

- Karnofsky performance status (KPS) > 70

- Neutrophil count > 1.5 x 10^9/L

- Platelet count > 100 x 10^9/L

- Bilirubin < 1.5 x upper limit of normal (ULN)

- Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) < 2.5 x ULN or
< 5 x ULN if patient has documented liver metastases

- Serum creatinine < 1.5 x ULN

Exclusion Criteria:

- Evidence of brain metastases on magnetic resonance imaging (MRI) of brain with and
without contrast

- History of other prior malignancy except for superficial skin cancers

- No severe comorbidities:

- History of significant cardiovascular disease unless the disease is well
controlled. Significant cardiac disease includes second/third degree heart block;
significant ischemic heart disease; poorly controlled hypertension; congestive
heart failure of the New York

- Heart Association (NYHA) Class II or worse (slight limitation of physical
activity; comfortable at rest, but ordinary activity results in fatigue,
palpitation or dyspnea)

- History of arrhythmia that is symptomatic or requires treatment. Patients with
atrial fibrillation or flutter controlled by medication are not excluded from
participation in the trial

- History of cerebrovascular accident (CVA) within 6 months prior to start of study
treatment

- Active infection or serious underlying medical condition that would impair the
ability of the patient to received protocol therapy

- History of any psychiatric condition that might impair patient's ability to
understand or comply with the requirements of the study or to provide consent

- Active implantable electronic medical devices in the brain; a skull defect, a shunt,
or bullet fragments

- Known allergies to medical adhesives or hydrogel

- Unable to operate the NovoTTF-200A device independently or with the help of a
caregiver

- If a female, currently pregnant, breastfeeding, or unwilling to avoid pregnancy while
on study treatment

- Concurrent brain directed therapy (beyond NovoTTF-200A as per protocol)

- Prior clinical trial participation with brain directed therapy

- Concurrent treatment clinical trials
