Conditions studied: Glioblastoma, Glioma, Gliosarcoma

In brief

This phase II trial will investigate the efficacy and safety of the addition of Optune (Tumor Treating Fields \[TTFields\] Therapy) to bevacizumab for patients with bevacizumab-refractory recurrent glioblastoma.

Who can join

Age: 22 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically proven diagnosis of glioblastoma or other grade IV malignant glioma (including variants of glioblastoma i.e., gliosarcoma, giant cell glioblastoma, etc.).
• Confirmation of tumor recurrence or progression on contrast magnetic resonance imaging (MRI) (with and without gadolinium contrast) as determined by Response assessment in neuro-oncology (RANO) criteria within 14 days prior to registration for patients who did not have recent resection of their glioblastoma or only had a stereotactic biopsy.
• Patients having undergone recent resection (within 5 weeks prior to registration) of their glioblastoma to treat current recurrence prior to study treatment must have recovered from the effects of surgery (including patient's skin having fully recovered from the surgical wound) Note: a 4-week window is required after surgery prior to starting treatment. For central nervous system (CNS) -related stereotactic biopsies, a minimum of 7 days must have elapsed prior to registration.
• Residual disease of recurrent glioblastoma is not mandated for eligibility into the study. To best assess the extent of residual disease post-operatively, a post-operative MRI scan must be performed prior to registration and is recommended to be within 96 hours post-surgery (although 24-48 hours would be optimum). Note: Patients who did have surgery with a post-operative contrast-enhanced scan falling outside the 5-week window prior to registration, must have a repeat MRI scan within 14 days prior to registration.
• Patients with up to two recurrences are allowed.
• Failure on bevacizumab (either as a monotherapy or a combination) as most recent regimen confirmed by tumor recurrence on MRI.
• The patient must have failed no more than one regimen of bevacizumab.
• The patient must not have received bevacizumab as an upfront treatment in newly diagnosed glioblastoma.
• There must be a minimum of 14 days (i.e., an interval equal to or greater than 14 days) since last treatment with bevacizumab and registration
• History/physical examination within 14 days prior to registration
• Karnofsky performance status ≥ 70 within 14 days prior to registration
• Age ≥ 22
• Absolute neutrophil count (ANC) ≥ 1,000 cells/mm3
• Platelets ≥ 75,000 cells/mm3
• Hemoglobin (Hgb) ≥ 9.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 9.0 g/dl is acceptable.)
• Creatinine ≤ 1.5 mg/dl
• Urine protein: creatinine (UPC) ratio < 1.0 within 14 days prior to registration OR urine dipstick for proteinuria ≤ 2+ (patients discovered to have > 2+ proteinuria on dipstick urinalysis at baseline must have a UPC ratio done that is <1.0 to be eligible. If the UPC ratio is ≥ 1.0 then the patients should undergo a 24-hour urine collection and must demonstrate ≤ 1g of protein in 24 hours to be eligible).
• Note: UPC ratio of spot urine is an estimation of the 24-hour urine protein excretion; a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1 gm. UPC ratio is calculated using one of the following formulas:
• [urine protein]/[urine creatinine]: if both protein and creatinine are reported in mg/dL
• [(urine protein) x0.088]/[urine creatinine]: if urine creatinine is reported in mmol/L
• Serum total bilirubin ≤ 1.5 x upper limit of normal (ULN) within 14 days prior to registration
• Alanine transaminase (ALT) and aspartate transaminase (AST) ≤ 3.0 x ULN within 14 days prior to registration
• Patients on full dose anticoagulants (e.g., warfarin or low molecular weight (LMW) heparin) must meet both of the following criteria:
• No active bleeding or pathological condition that carries a high risk of bleeding (e.g., tumor involving major vessels or known varices) within 14 days prior to registration
• One of the below criteria must be met based on patient's therapy:

You may not qualify if…

• Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years. (For example, carcinoma in situ of the breast, oral cavity, or cervix are all permissible).
• Infra-tentorial tumor.
• > 1 cm diameter of blood seen on contrast MRI (with and without gadolinium contrast)
• Major surgery such as intra-thoracic, intra-abdominal or intra-pelvic (with the exception of craniotomy), open biopsy or significant traumatic injury ≤ 4 weeks prior to registration, or patients who have had minor procedures, percutaneous biopsies or placement of vascular access device ≤ 1 week prior to registration, or who have not recovered from side effects of such procedure or injury.
• Implanted pacemaker, defibrillator or deep brain stimulator, other implanted electronic devices in the brain.
• Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months prior to registration.
• Transmural myocardial infarction within the last 6 months prior to registration
• Cerebrovascular accident (CVA), transient ischemic attack (TIA) within the last 6 months prior to registration
• Pulmonary embolism (PE) within the last 6 months prior to registration
• Uncontrolled hypertension (defined by a systolic blood pressure (SBP) ≥ 160 mm Hg or diastolic blood pressure (DBP) ≥ 100 mm Hg while on anti-hypertensive medications) within 14 days prior to registration.
• Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration.
• Chronic lung disease or Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration.
• Severe hepatic disease, defined as a diagnosis of Child-Pugh Class B or C hepatic disease.
• Known HIV positive patients.
• 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.
• Skull defects such as missing bone flap, a shunt, or bullet fragments.
• Significant intracranial pressure as per treating physician that may require surgical intervention.
• Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception.
• Breast feeding women.
• Prior allergic reaction to bevacizumab or severe adverse event with bevacizumab.
• Known sensitivity to conductive hydrogels.
• Prior treatment with the Optune® system.
• Active treatment on another clinical trial.
