Summary

This study is a prospective single arm trial designed to study the safety, feasibility and preliminary efficacy of a medical device, NovoTTF-200A used concomitantly with standard adjuvant treatment for newly diagnosed glioblastoma.

Detailed description

A prospective, single arm, non-randomized, open label pilot trial will enroll ten patients with histologically-confirmed newly diagnosed GBM who meet all eligibility criteria. Patients will be recruited to the study by the principal investigator (PI) or one of the co-investigators (CI) at one institution, Hackensack University Medical Center. Accrual is expected to continue for 18 months. The protocol has a planned enrollment of 10 patients. Should patients discontinue treatment on protocol for reasons unrelated to toxicity (e.g. lost to follow-up, withdrawal of consent), additional patient (s) may be enrolled to complete enrollment. Following maximal debulking surgery, patients will undergo a gadolinium enhanced brain MRI within 72 hours and a screening visit 2 to 4 weeks following surgery. Extent of resection will be recorded as biopsy, partial resection or gross-total resection based upon residual enhancing tumor on post-operative MRI.The day prior to XRT start, patients will have a clinic visit for training and application of the NovoTTF-200A device. During this visit, the patient will be educated regarding general use and maintenance of the device, with a particular focus upon strategies to prevent, identify and manage dermatologic adverse events (dAE). Temozolomide will be dosed nightly during XRT as per standard of care, and NovoTTF-200A will be worn continuously, removed during XRT and replaced as soon as possible thereafter. During XRT and for 12 weeks to follow, the patient will have study visits at regular intervals (TAB A) for a physical examination and to assess toxicity and device compliance. Visits outlined in TAB A are in addition to weekly visits during radiotherapy with the treating radiation oncologist. MRI will be obtained at 4 weeks (+/-7 days) and 12 weeks (+/-7 days) following completion of XRT, and maintenance temozolomide will recommence in 5/28 day cycles as per standard of care. Objective response will be assessed as defined by the Response Assessment in Neuro-Oncology (RANO) criteria (TAB C) by the treating physician and confirmed by a second investigator. In the case of suspected pseudoprogression, continued treatment and subsequent evaluations will help clarify whether it is true progression. Patients may continue treatment at the discretion of the investigator. If subsequent evaluations suggest that the tumor has in fact progressed, the date of progression will reflex to the date when the issue was first raised. However, if subsequent evaluations demonstrate improvement without change in therapy, the initial tumor increase may be considered pseudoprogression and response may be recorded as not evaluable for that time point. In the case of clinical progression, an unscheduled MRI will be obtained within 1 week of the investigator becoming aware of the clinical progression. No additional MRIs will be required after progression. Temozolomide and NovoTTF-200A will continue until the final study visit, or until disease progression or unacceptable toxicity. Thereafter, temozolomide, MRI and response assessments will continue as per standard of care. Following the final study visit, the patient will be followed at a minimum of every two months for survival, either by phone or in person. If the patient is free of unacceptable toxicity attributable to NovoTTF-200A, they will be offered the opportunity to continue the device at no financial cost, but without obligation to do so. Unacceptable toxicity includes the occurrence of device related serious adverse events or clinical and functional deterioration considered by the investigator to be prohibitive of continuing treatment. Treatment with the NovoTTF-200A device does not need to be terminated in the case of temozolomide toxicity. The primary endpoint will be safety and tolerability of combined modality treatment with radiotherapy, temozolomide and NovoTTF-200A, based upon the incidence and severity of adverse events. Secondary endpoints will be overall survival, progression free survival and quality of life.

Conditions

• Glioblastoma, Adult

Interventions

Type	Name	Description
DEVICE	NovoTTF-200A	* Begins the day prior to radiotherapy start and continues until the end of temozolomide maintenance cycle #2 or until evidence of disease progression or unacceptable toxicity. * Arrays are removed immediately prior to radiotherapy and replaced immediately thereafter.
DRUG	Temozolomide	Concomitant phase: * 75 mg/m2 per day for 42 days concomitant with radiotherapy. * Begins 1 day prior to XRT start. Maintenance phase: * Begins 4 weeks after concomitant phase completion (+/- 1 week). * Each cycle is 28 days (5 days of drug treatment followed by 23 days without). * Cycle 1: 150 mg/m2 once daily for the first 5 days of each treatment cycle. * Subsequent cycles: daily dose increased to 200 mg/m2, if the CTC non-hematologic toxicity for Cycle 1 is Grade ≤ 2 (except for alopecia, nausea and vomiting), absolute neutrophil count (ANC) is ≥ 1.5 x 109/L, and the platelet count is ≥ 100 x 109/L. The dose remains at 200 mg/m2 per day for the first 5 days of each subsequent cycle except if toxicity occurs.
RADIATION	3D conformal or intensity modulated radiation therapy (IMRT)	Radiotherapy will commence 4 weeks after the definitive surgical procedure (+/- 1 week), to a total dose of 54.0 - 60.0 Gy, delivered in 1.8 - 2.0 Gy fractions over 6 - 7 weeks. XRT target volumes will be determined utilizing all available imaging studies that best delineate extent of disease. Fusion image registration for treatment planning will be utilized as possible. Either 3D conformal or intensity modulated radiation therapy (IMRT) will be utilized.
