A prospective phase II trial of NovoTTF-100A with Bevacizumab (Avastin) in Patients with Recurrent Glioblastoma
- To determine the efficacy of the combination of bevacizumab and NovoTTF-100A in bevacizumab-naive patients with recurrent GBM as measured by 6-month progression-free survival (PFS6)
- To assess safety and tolerability of the combination of bevacizumab and NovoTTF-100A in this population
- To evaluate overall survival in this population
- To determine objective response rate (ORR) by modified RANO criteria in this population
- To assess time-to-progression in this population
- To assess neurocognitive outcome and quality of life in this population
- Patients with histologically confirmed glioblastoma or other grade IV malignant glioma (i.e. gliosarcoma, small cell glioblastoma, etc.), recurrent after prior external-beam fractionated radiotherapy and temozolomide chemotherapy.
- Patients with up to two prior recurrences are allowed.
- Karnofsky performance status ≥ 70.
- Age ≥ 22 years old.
- Patients must have the following laboratory values:
- Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L
- Platelets ≥ 100 x 10^9/L
- Hemoglobin (Hgb) > 9 g/dL
- Serum total bilirubin le;1.5 x ULN
- ALT and AST ≤ 3.0 x ULN
- Serum creatinine ≤ 1.5 x ULN
- Blood coagulation parameters: INR ≤ 1.5
- Minimum interval since completion of radiation treatment is 12 weeks
- Minimum interval since last drug therapy
- 3 weeks since last non-cytotoxic therapy
- 3 weeks must have elapsed since the completion of a non-nitrosourea-containing chemotherapy regimen
- 6 weeks since the completion of a nitrosourea-containing chemotherapy regimen.
- Patients must have signed an approved informed consent and authorization permitting release of personal health information.
- Patients with the potential for pregnancy or impregnating their partner must agree to follow acceptable birth control methods to avoid conception. The effects of bevacizumab on developing fetus or nursing infant are not known. Female patients of child-bearing potential must have a negative pregnancy test.
- Patients must have no concurrent malignancy except curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix and breast, adequately treated stage I or II cancer from which the patient is in complete remission. Patients with other prior malignancies must be disease-free for ≥ three years.
- Patients must be maintained on a stable corticosteroid regimen from the time of their baseline scan until the start of treatment and/or for at least 5 days before starting treatment.
- Patients who have had previous treatment with bevacizumab.
- Patients who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury ≤ 4 weeks prior to starting study drug, or patients who have had minor procedures, percutaneous biopsies or placement of vascular access device ≤ 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury
- Patients with impaired cardiac function or clinically significant cardiac diseases, including any of the following:
- History or presence of serious uncontrolled ventricular arrhythmias
- Any of the following within 6 months prior to starting study drug: myocardial infarction (MI), severe/unstable angina, Coronary Artery Bypass Graft (CABG), Congestive Heart Failure (CHF), Cerebrovascular Accident (CVA), Transient Ischemic Attack (TIA), Pulmonary Embolism (PE)
- Uncontrolled hypertension (defined by a SBP ≥ 160 mm Hg or DBP ≥ 100 mm Hg while on anti-hypertensive medications)
- Patients with cirrhosis, or active viral or nonviral hepatitis.
- Implanted pacemaker, defibrillator or deep brain stimulator, other implanted electronic devices in the brain or documented clinically significant arrhythmias.
- Infra-tentorial tumor
- Evidence of increased intracranial pressure (clinically significant papilledema, vomiting and nausea or reduced level of consciousness)
- Known sensitivity to conductive hydrogels
- Known diagnosis of human immunodeficiency virus (HIV) infection (HIV testing is not mandatory)
- Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g. active or uncontrolled infection, uncontrolled diabetes) that could cause unacceptable safety risks or compromise compliance with the protocol
- Pregnant or breast-feeding women
- Patients unwilling or unable to comply with the protocol
