Study Bendamustine Concurrent Whole Brain Radiation Brain Metastases From Solid Tumors

This is an interventional treatment trial for Brain Metastases focused on measuring Brain and Nervous System Read More

Inclusion Criteria:

• Pathologically (histologically or cytologically) proven diagnosis of solid tumor malignancy within 5 years of registration. Pathological confirmation by pathologists at Moffitt Cancer Center is required.
• Cerebral metastases from known solid tumors diagnosed by contrast-enhanced brain magnetic resonance imaging (MRI) or contrast-enhanced head computed tomography (CT) for patients unable to receive MRIs
• Single metastases that have been resected
• Patient may have had prior radiosurgery or surgical resection for brain metastasis. Patients should have completed prior therapy at least 14 days but no longer than 56 days prior to study entry.
• Karnofsky Performance Status ≥ 70 within 28 days prior to study entry.
• Expected life span of ≥ 3 months
• Able to tolerate 3 week course of whole brain radiation therapy
• Able to receive a lumbar puncture (for post-MTD patients only)
• Adequate bone marrow, liver and renal function as assessed by the following: Hemoglobin > 9.0 g/dl; Absolute neutrophil count (ANC) > 1,500/mm³; Platelet count > 100,000/mm³; Total bilirubin < 1.5 x upper limit of normal (ULN); Alanine transaminase/Aspartic transaminase (ALT/AST) < 2.5 x the ULN (< 5 x ULN for patients with liver involvement); International normalized ratio (INR) < 1.5 or a prothrombin time/partial thromboplastin time (PT/PTT) within normal limits; Creatinine < 1.5 x ULN
• Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment.
• Ability to understand and sign a study-specific written informed consent prior to study entry.
• Patients receiving systemic therapy are eligible for this study if given >14 days prior to study entry and given no sooner than >14 days post radiation therapy (RT) completion.
• Complete history and general physical examination within 28 days prior to study entry

Exclusion Criteria:

• Known hypersensitivity to bendamustine or mannitol
• Patients with cerebral metastases from unknown primary tumors
• Patients with cerebral metastases from leukemias or lymphomas
• Patients with uncontrolled systemic cancer (i.e. evidence of systemic disease progression < 3 months prior to study entry)
• Systemic chemotherapy ≤14 days prior to study entry or ≤14 days after completing radiotherapy
• Patients who received prior BCNU wafer (Gliadel®) implantation for surgically resected cerebral metastatic lesions
• Patients with a life expectancy of less than 3 months
• Patients who received prior whole brain radiation therapy. As noted above, patients who received prior radiosurgery are allowed
• Patients with significant hydrocephalous
• Active clinically serious infection > Common Terminology Criteria for Adverse Events (CTCAE) Grade 2
