About

This pilot early phase I trial studies the side effects of temozolomide, radiation therapy, and tumor treating fields therapy using Novo tumor treatment fields (TTF)-200A device in participants with glioblastoma. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. NovoTTF-200A device is a portable device that produces alternating electrical fields that may disrupt growth of cancer cells. Giving temozolomide, radiation therapy, and tumor treating fields therapy using NovoTTF-200A device may work better in treating participants with glioblastoma.

Full description

PRIMARY OBJECTIVES:

I. To evaluate the safety and toxicity of combination chemoradiotherapy with NovoTTF-200A device (Optune) treatment in newly diagnosed glioblastoma.

SECONDARY OBJECTIVES:

I. To determine the median progression-free survival of patients with newly diagnosed glioblastoma treated with radiotherapy with concurrent and adjuvant temozolomide plus Optune.

II. To evaluate the median overall survival, 1-year overall survival, and event-free survival.

III. Collect tumor O(6)-Methylguanine-DNA-methyltransferase (MGMT) methylation status and isocitrate dehydrogenase (IDH) mutation status.

IV. To evaluate the level of circulating tumor deoxyribonucleic acid (DNA) in glioblastoma patient serum during treatment.

V. To evaluate the quality of life of patients treated with radiotherapy with concurrent and adjuvant temozolomide plus Optune.

Allocation: N/A

Interventional model: Single Group Assignment

Masking: None (Open label)

---

30 participants in 1 patient group

Treatment (temozolomide, radiation, NovoTTF-200A device)

Experimental group

Description:

Participants receive temozolomide PO QD starting day 1 to the end of radiation therapy and undergo 30 fractions of radiation therapy over 15-20 minutes each, 5 days a week (Monday-Friday) for 6 weeks. Beginning day 1 of radiation therapy, participants undergo tumor treatment fields therapy using NovoTTF-200A device over 18 hours or more daily in the absence of disease progression or unacceptable toxicity. Beginning 28 days after the last dose of radiation therapy, participants receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Treatment:

Procedure: Tumor Treating Fields Therapy

Radiation: Radiation Therapy

Device: NovoTTF-200A Device

Drug: Temozolomide
