Effect of TTFields (150 kHz) in Non-small Cell Lung Cancer (NSCLC) Patients With 1-10 Brain Metastases Following Radiosurgery (METIS)

Overview

About this study

The study is a prospective, randomized controlled phase III trial, to test the efficacy, safety and neurocognitive outcomes of advanced NSCLC patients, following stereotactic radiosurgery (SRS) for 1-10 brain metastases, treated with NovoTTF-100M compared to supportive treatment alone. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields or TTF) to the region of the malignant tumor, by means of surface, insulated electrode arrays.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • 18 years of age and older.
  • Life expectancy of ≥ 3 months.
  • New diagnosis of brain metastases from a histologically or cytologically confirmed primary or metastatic NSCLC tumor within 5 years of registration on the study. If the original histological proof of malignancy is greater than 5 years, then pathological confirmation is required (i.e., from extra-cranial or intracranial disease).
  • Karnofsky performance status (KPS) ≥ 70
  • 1 inoperable brain metastasis or 2- 10 brain lesions per screening MRI, confirmed by contrast enhanced MRI amenable to SRS according to the following criteria:
    • largest tumor volume < 10 cc;
    • longest tumor diameter < 3 cm;
    • Cumulative volume of all tumors ≤ 15 cc.
  • At least one measurable lesion per RANO-BM (Response Assessment in Neuro-Oncology Brain Metastases) Criteria for brain metastasis.
  • Patients must be receiving optimal therapy for their extracranial disease according to local practice at each center. Patients may continue on systemic therapy while receiving TTFields.
  • Able to operate the NovoTTF-100M device independently or with the help of a caregiver.
  • Clinical trials prior to enrollment are allowed, as long as no brain directed therapy was included (current treatment trials are exclusionary).

Exclusion Criteria:

  • Patients who are known to have somatic tumor mutations in the following genes, for which targeted agents are available that directly affect the treatment of brain metastasis: Anaplastic lymphoma kinase (ALK), epidermal growth factor receptor (EGFR), ROS-1 proto-oncogene, and proto-oncogene B-RAF.
  • Patients who have a single, operable brain metastasis.
  • Patients with significant edema leading to risk of brain herniation.
  • Patients with midline shift > 10mm.
  • Patients with intractable seizures.
  • Leptomeningeal metastases.
  • Recurrent brain metastases.
  • Prior WBRT for newly diagnosed brain metastases.
  • Severe comorbidities:
    • Clinically-significant inadequate hematological, hepatic and renal function, defined as: Neutrophil count < 1.5 x 10^9/L and platelet count < 100 x 10^9/L; bilirubin > 1.5 x upper limit of normal (ULN); aspartate transaminase (AST) and/or alanine aminotransferase (ALT) > 2.5 x ULN or > 5 x ULN if patient has documented liver metastases; and serum creatinine > 1.5 x ULN;
    • 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 randomization or that is not stable;
    • 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.
  • Implantable electronic medical devices in the brain.
  • Known allergies to medical adhesives or hydrogel.
  • Currently pregnant or breastfeeding.
  • Concurrent brain directed therapy (beyond SRS and NovoTTF-100M as per protocol).
