Protocol Summary

Protocol No.: OCR14655

Protocol Title: NovoTTF Therapy in Treating Patients With Recurrent Glioblastoma Multiforme

Principal Investigator: Tran, David

Objective: This pilot phase II trial studies how well Novocure's Tumor Treating Electric Fields (NovoTTF) therapy works in treating patients with recurrent glioblastoma multiforme. NovoTTF therapy uses a low intensity electric current to kill tumor cells. NovoTTF therapy may be effective treatment for brain cancer.

Phase: Phase II

Age Group: Adult

Age: 22 Years - N/A

Gender: All

Scope: Local

Treatment:
NovoTTF therapy:
Patients undergo NovoTFF therapy at least 18 hours daily for 6 months (bevacizumab-naive) or 4 months (bevacizumab-refractory). Treatment may continue for up to 2 years in patients experiencing CR, PR, or SD.

Detailed Eligibility:
INCLUSION CRITERIA:
1. Ages 22 years old and older
2. Histologically confirmed GBM (WHO grade IV); rare GBM variants (e.g. gliosarcoma, giant cell GBM, small cell GBM, GBM with oligodendroglioma features, GBM with PNET features) are allowed. Patients will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of GBM is made.
3. Received radiotherapy of at least 45 Gy and temozolomide chemotherapy as initial treatment for GBM.
4. Unequivocal evidence of recurrent or progressive GBM before or after bevacizumab treatment first based on radiographic appearances then confirmed by histologic confirmation through biopsy or resection.
5. Prior treatment with Gliadel wafer is allowed if it has been at least 3 months from placement.
6. There must be an interval of at least 12 weeks from the completion of radiotherapy to start of device treatment. When the interval is less than 12 weeks from the completion of radiotherapy, the histological confirmation of progression must be unequivocal per RANO criteria. The use of PET scan, perfusion imaging, and MRspectroscopy to differentiate between true early progression and pseudoprogression prior to biopsy or resection of probable recurrent tumor is per standard of care.
7. Karnofsky performance status of at least 60%.
8. Life expectancy of at least 3 months.
9. Planned biopsy or resection of recurrent tumor for therapeutic and/or diagnostic purpose, and with adequate bone marrow, hepatic, cardiac, and renal function to undergo this planned procedure.
10. For patients who have undergone or will undergo stereotactic biopsy of recurrent or progressive tumor, a post-operative MRI is not required, provided that the pre-biopsy MRI is within 21 days of registration. If the preoperative scan is more than 21 days before registration, the scan needs to be repeated. If the steroid dose is increased more than 50% between the date of biopsy and registration, a new baseline MRI is required on a stable or decreasing steroid dosage for at least 3 days even if the previous MRI was within 21 days of registration.
11. For patients who have undergone or will undergo open resection of recurrent or progressive tumor, residual disease following resection is not mandated for eligibility into the study. To best assess the extent of residual disease post-resection, a MRI scan should be done no later than 96 hours in the immediate post-resection period and within 21 days prior to registration. If the 96-hour scan is more than 21 days before registration, the scan needs to be repeated. If the steroid dose is increased more than 50% between the date of imaging and registration, a new baseline MRI is required on a stable or decreasing steroid dosage for at least 3 days.
12. Planned treatment with NovoTTF Therapy alone per FDA-approved indication. NovoTTF Therapy must start within 14 days of registration, but not less than 7 days or more than 21 days from stereotactic biopsy (if applicable) and not less than 21 days or more than 42 days from open resection (if applicable).
13. Availability of tissue from the initial diagnosis and the recurrent tumor that is estimated to be of sufficient quality and quantity for both genomic DNA and total RNA isolation; preferably some of the tissue would be snap frozen for high quality RNA preparation.
14. Because the genetic analyses described in Section 8.0 will be performed under HRPO# 201111001 ("Analysis of Histological, Genomic, Molecular, and Clinical Factors in CNS Cancer: the Neuro-Oncology Group"), for patients enrolling in this trial at WUSM, it is required that WUSM patients must also enroll in HRPO# 201111001. The genetic analyses for UF patients will take place at WUSM under the auspices of this protocol.
15. Recovery from the toxic effects of prior therapy to not more than grade 1 or >3 weeks from prior therapy to registration, whichever is later.
