  • A Study to Compare Whole Brain Radiotherapy and Memantine to Stereotactic Radiosurgery vs. Stereotactic Radiosurgery Alone to Treat Patients with Cancer That Has Spread to the Brain After Earlier Stereotactic Radiosurgery Jacksonville, FL

    The purpose of this study is to compare the effect of adding whole brain radiotherapy with hippocampal avoidance and memantine to stereotactic radiosurgery versus stereotactic radiosurgery alone in treating patients with cancer that has spread to the brain and come back in other areas of the brain after earlier stereotactic radiosurgery. Hippocampus avoidance during whole-brain radiation therapy decreases the amount of radiation that is delivered to the hippocampus, which is a brain structure that is important for memory.

    The medicine memantine is also often given with whole brain radiation therapy because it may decrease the risk of side effects of radiation on ...

  • A Study to Evaluate Stereotactic Radiosurgery Versus Hippocampal-Avoidant Whole Brain Radiotherapy for 10 or Fewer Brain Metastases from Small Cell Lung Cancer Scottsdale/Phoenix, AZ

    The primary objective of this study is to determine whether stereotactic radiosurgery (SRS) relative to whole brain radiotherapy with hippocampal avoidance (HA-WBRT) plus memantine for brain metastases from small cell lung cancer (SCLC) prevents cognitive function failure as measured by cognitive decline on a battery of tests: the Hopkins Verbal Learning Test – Revised (HVLT-R), Controled Oral Word Association (COWA) test, and the Trail Making Test (TMT). 

  • SPORT-DMG Rochester, MN; Scottsdale/Phoenix, AZ

    The purpose of this study is to evaluate the clinical outcomes of hypofractionation with planned courses of re-irradiation for patients with diffuse midline gliomas of the pons.

    Subjects will be screened by neurosurgery, radiation oncology, or pediatric oncology at outpatient clinic or by the multidisciplinary pediatric central nervous system tumor conference. Interested qualified patients and their families will be consented and offered participation in this study

  • FRACTIONATE Rochester, MN; Scottsdale/Phoenix, AZ; Jacksonville, FL

    All lesions 4.0 cm to 6.0 cm will receive 32.5 Gy/5 fractions and will be analyzed separately.  The portion of the trial is written as a phase II study without randomization noting the rarity of unresected brain metastasis of this size and the lack of comfort of treating radiation oncologist and neurosurgeons with single fraction SRS for tumors this large. However, noting the paucity of prospective data for this patient population enrolling patients on a clinical trial will provide a more accurate historical control for future trials.  Although this cohort was enrolled on the prospective phase I trial from ...

  • A Study to Compare Stereotactic Radiosurgery to Hippocampal-Avoidant Whole Brain Radiotherapy Jacksonville, FL; Rochester, MN

    The purpose of this study is to compare stereotactic radiosurgery (SRS) to whole brain radiotherapy (WBRT) in patients with 5 or more brain metastases.

  • Corticosteroids + Bevacizumab vs. Corticosteroids + Placebo (BEST) for Radiation Injury After Treatment for Brain Metastases Rochester, MN

    This randomized phase II study aims to investigate whether the addition of bevacizumab to standard corticosteroid therapy results in greater improvement in symptoms and less treatment-induced symptoms compared with standard corticosteroid therapy for patients with symptomatic brain radionecrosis following radiosurgery. It is hypothesized that the addition of bevacizumab to standard care corticosteroids will reduce treatment-induced toxicities and improve neurologic impairments in patients with brain radionecrosis following radiosurgery for brain metastases.

  • A Study to Compare Single Fraction Stereotactic Radiosurgery Compared with Fractionated Stereotactic Radiosurgery in Treating Patients With Resected Metastatic Brain Disease Jacksonville, FL; Rochester, MN; Scottsdale/Phoenix, AZ

    The purpose of this study is to compare how well single fraction stereotactic radiosurgery works versus fractionated stereotactic radiosurgery in treating patients with cancer that has spread to the brain from other parts of the body and has been removed by surgery. Single fraction stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Fractionated stereotactic radiosurgery delivers multiple, smaller doses of radiation therapy over time.

  • The NeoGlioma Study Jacksonville, FL

    This study aims to evaluate the safety of preoperative radiosurgery in the treatment of patients with biopsy-proven high grade glioma prior to conventional therapy. Safety is defined as any acute grade 3 (CTCAE v5.0) or greater unplanned adverse event from the time of enrollment until 4 weeks following postoperative radiotherapy.

  • Pre-operative vs. Post-operative Radiosurgery for Metastatic Brain Tumors Scottsdale/Phoenix, AZ; Jacksonville, FL; Rochester, MN

    The purpose of this study is to determine whether there is an increase in the time of a first occurrence of either: local recurrence, leptomeningeal disease, or symptomatic radiation brain necrosis in patients with brain metastases who receive SRS prior to surgery as compared to patients who receive surgery prior to SRS.

     

  • Short Course Radiotherapy for the Treatment of Patients With Glioblastoma, SAGA Study Scottsdale/Phoenix, AZ; Rochester, MN; Jacksonville, FL

    The purpose of this study is to demonstrate non-inferior 12-month overall survival of patients with GlioblastomA (GBM) treated with dose escalated hypofractionated radiotherapy compared to standard of care. Also, to demonstrate the safety and favorable quality of life via physician-reported G3+ toxicitycompare if SBRT is non-inferior to standard of care on the proportion of overall survival of patients with glioblastoma 12 months after randomization.

     

  • Treatment of Brain AVMs (TOBAS) Study Jacksonville, FL

    The purpose of this study is to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty.

  • A Registry for Children Treated with Proton Radiation Therapy Rochester, MN

    The purpose of the Pediatric Proton Consortium Registry (PPCR) is to enroll children who have been treated with proton radiation in the United States in order to describe the population that currently receives protons and better evaluate its benefits over other therapies. The data collected from this study will help facilitate research on proton beam radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data which many centers that deliver proton radiation therapy already collect in routine operations.

  • A Study to Compare Optimal MRI Timing for Pre-surgical Planning to LINAC-based Therapy Rochester, MN

    The purpose of this research is to compare two different standard-of-care pre-surgical imaging methods. 

  • A Study of Nivolumab and Multi-fraction Stereotactic Radiosurgery with or without Ipilimumab in Treating Participants with Recurrent Grade II-III Meningioma Scottsdale/Phoenix, AZ; Jacksonville, FL; Rochester, MN

    The purpose of this study is to evaluate the side effects and best dose of nivolumab when given together with multi-fraction stereotactic radiosurgery and to see how well they work with or without ipilimumab in treating participants with grade II-III meningioma that has come back. Monoclonal antibodies, such as nivolumab and ipilimumab, may interfere with the ability of tumor cells to grow and spread. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. It is not yet known whether giving nivolumab and multi-fraction ...

  • A Study of Using Geometrically Accurate Functional MRI to Enable Personalized Radiotherapy of Glioblastoma Scottsdale/Phoenix, AZ

    The purpose of this study is to create a new Magnetic resonance imaging (MRI) technique with true contrast to the background reference points in functional MR images of individual patients. Functional MRI has been widely used in staging, grading and treatment response monitoring of glioblastoma.  MRI has great soft tissue and tumor tissue contrast and can assist in outlining the target. It has proven able to offer functional information such as cell density, permeability of the micro-blood vessels, and the oxygen level of the tumor.

  • Intervention for Children Undergoing Proton Radiation for Brain Cancer Rochester, MN

    The purpose of this study is to develop and pilot a novel early intervention program for children undergoing proton radiation thereapy (PRT) for brain tumors.

    Survivors of childhood brain cancers who undergo radiation therapy can have damage to normal brain tissue.  Activities such as attention training and physical exercise can improve mental function in children with brain injury that is caused by the radiation therapy.  Improvements in children’s ability to learn, behavior and fitness will lead to a better developmental outcome and quality of life in the longer term.
