     OUTLINE: This is a multicenter, phase I, dose-escalation study (Phase I completed) of dasatinib followed by a phase II randomized study. Patients are grouped according to study (1 vs 2). Patients in the phase II portion are stratified according to age (> 70 years of age vs ≤ 70 years of age), and ECOG performance status (0 vs 1 or 2).

     Phase I: Patients receive bevacizumab IV over 30-90 minutes on day 1. Patients also receive oral dasatinib once or twice daily on days 1-14 until the maximum-tolerated dose (MTD) is determined. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. (Phase I completed)

     Phase II (patients are randomized to 1 of 2 treatment arms):

       -  Arm I: Patients receive bevacizumab as in phase I and dasatinib at the MTD as determined in phase I. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

       -  Arm II: Patients receive bevacizumab as in phase I and oral placebo once or twice daily on days 1-14. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

     Quality of life is assessed by FACT-Br questionnaire at baseline and prior to every other course (no longer assessed as of 5/18/2009)(newly added as of 2/2/2010). Tissue samples are collected at baseline for biomarker studies and assessed by IHC, RT-PCR, and FISH. Patients undergo dynamic contrast-enhanced MRI at baseline, day 3 of course 1, and day 1 of course 2.

     After completion of study therapy, patients are followed up periodically for up to 3 years.

PRIMARY OBJECTIVES: I. To assess the anti-tumor activity (in terms of the tumor response rate using the Response Evaluation Criteria in Solid Tumors [RECIST] criteria) of pazopanib (pazopanib hydrochloride) (GW786034) in patients with advanced malignant pheochromocytomas and paragangliomas. SECONDARY OBJEC TIVES: I. To assess safety profile of pazopanib. II. To assess duration of tumor response. III. To assess time to treatment failure. IV. To assess progression-free survival time. V. To assess overall survival time. TERTIARY OBJECTIVES: I. For patients with secretory tumors, to examine changes in urinary catecholamine and/or metanephrine levels. II. For patients with secretory tumors, to examine whether pazopanib-induced changes in urinary catecholamine and/or metanephrine levels during the first cycle of treatment may be associated with objective tumor response. III. To examine associations between tumor response and somatic mutational status in archived tumors, or germline mutational status in patient's peripheral blood mononuclear cells, (presence of succinate dehydrogenase complex subunit D [SDHD], succinate dehydrogenase complex subunit B [SDHB], ret proto-oncogene [RET], von Hippel-Lindau tumor suppressor [VHL], neurofibromatosis type-1). IV. To examine associations between tumor response and tumor expression levels of angiogenic and vascular markers including hypoxia inducible factor 1, alpha (HIF-1a), vascular endothelial growth factor receptor (VEGF-R) (total and phospho-) and microvessel density in archival tumor tissue. IV. To examine whether the extent of tumor response/regression may be correlated with plasma pazopanib (GW786034) concentration achieved after the third cycle (first cycle after run-in cycles) of pazopanib (GW786034) therapy. OUTLINE: This is a multicenter study. Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo urine and blood sample collection at baseline and periodically during study for correlative studies. After completion of study therapy, patients are followed up every 3-6 months for a maximum of 3 years.

OBJECTIVES:

     Primary

       -  Determine whether there is a survival advantage for patients with newly diagnosed 1p/19q codeleted anaplastic glioma who receive concurrent temozolomide and radiotherapy (RT) followed by adjuvant temozolomide over that observed in patients treated with RT alone (control).

     Secondary

       -  Determine whether there is a neurocognitive advantage in patients who receive temozolomide alone (Arm III) vs temozolomide with concurrent RT (Arm II) over that observed in patients treated with RT alone (Arm I).

       -  Determine whether there is a difference in survival based on t(1;19)(q10,p10) translocation status and MGMT promoter hypermethylation status in these patients.

       -  Perform descriptive comparisons of additional secondary outcome endpoints, including time to progression, progression free survival, and the proportion of patients free of progression at 6, 12, and 24 months.

       -  Determine the toxicity of RT and concurrent/adjuvant temozolomide in these patients.

       -  Determine descriptively whether it is reasonable to delay RT by documenting the time to progression and progression-free survival of patients receiving temozolomide alone.

       -  Determine the quality of life and neurocognitive effects in patients treated on this protocol and correlate these results with outcome endpoints.

       -  Bank blood products (i.e., plasma, DNA, and buffy coat) and tumor tissue for future scientific investigations.

     OUTLINE: This is a multicenter study. Patients are stratified according to cooperative group (EORTC vs North American groups [NCCTG, RTOG, CTSU, and NCIC CTG]), age (≤ 50 years vs > 50 years), and ECOG performance status (0-1 vs 2). Patients are randomized to 1 of 3 treatment arms.

       -  Arm I: Patients undergo radiotherapy (RT) 5 days a week for 6 weeks in the absence of disease progression or unacceptable toxicity.

       -  Arm II: Patients undergo RT as in arm I and receive oral temozolomide once daily on days 1-7 for 6 weeks. Beginning 4 weeks after completion of concurrent chemoradiotherapy, patients receive adjuvant oral temozolomide once daily days 1-5. Treatment with adjuvant temozolomide repeats every 28 days for 6-12 courses in the absence of disease progression and unacceptable toxicity.

       -  Arm III: Patients receive oral temozolomide once daily on days 1-5. Treatment repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.

     Patients complete neurocognitive questionnaires (i.e., the Hopkins Verbal Learning test, the Controlled Oral Word Association test from the Multilingual Aphasia Examination, General Mental Ability: Trail Making tests A and B, and the Recall and Recognition of Word List encoded from the HVLT-R test) and quality of life questionnaires (i.e., EORTC QOL-C30 and QOL-BN20) at baseline and periodically during study therapy.

     Tumor tissue samples are collected during surgery and analyzed by FISH to detect t(1:19), and for MGMT gene promoter hypermethylation status and additional known prognostic markers, including but not limited to PTEN, EGFR, EGFRvIII, and p53.

     After completion of study therapy, patients are followed periodically.

OBJECTIVES:

     Primary

       -  To determine whether the addition of temozolomide to fractionated radiotherapy improves the progression-free survival (PFS) of patients with symptomatic or progressive low-grade gliomas.

       -  To determine whether the addition of temozolomide to fractionated radiotherapy improves the median overall survival (OS) of these patients.

     Secondary

       -  To determine whether combination therapy with temozolomide and radiotherapy improves or maintains cognition and quality of life compared to radiotherapy alone.

       -  To compare the toxicities (severe or worse [≥ grade 3]) of radiotherapy with vs without temozolomide in these patients.

       -  To assess the impact of the presence or absence of 1p and 19q deletion on PFS and OS.

       -  To determine the impact of 1p and 19q status on PFS and OS of patients treated with temozolomide.

       -  To create a tumor and tissue bank, including plasma and germ line DNA, within the ECOG Pathology Coordinating Office.

     OUTLINE: This is a multicenter study. Patients are stratified according to age (< 40 years vs ≥ 40 years), 1p and 19q status (both deleted vs either/both intact vs undeterminable), pre-operative maximum tumor diameter (< 6 cm vs ≥ 6 cm [based on T2 or FLAIR MRI]), Karnofsky performance status (60-70% vs 80-100%), and contrast enhancement on pre-treatment MRI scan (present vs absent). Patients are randomized to 1 of 2 treatment arms.

       -  Arm I: Patients undergo 3-dimensional conformal or intensity-modulated radiotherapy once daily 5 days a week for 5½ weeks (28 fractions).

       -  Arm II: Patients undergo radiotherapy as in arm I and receive concurrent oral temozolomide once daily for 5½ weeks. Beginning 28 days after completion of chemoradiotherapy, patients receive oral temozolomide alone once daily on days 1-5. Treatment with temozolomide repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.

     Some patients undergo quality-of-life and neurocognitive (e.g., visual scanning speed, divided attention, language, memory, and fine motor skills) assessments at baseline, annually until disease progression, and at the time of disease progression.

     Tumor tissue samples are collected at baseline for confirmation of diagnosis and determination of 1p and 19q deletion status. Peripheral blood, serum, and additional tumor tissue samples may be collected for further research studies.

     After completion of study treatment, patients are followed up periodically for up to 15 years.

OBJECTIVES: - To evaluate the diagnostic and prognostic relevance of various molecular, cytogenetic, and other tumor markers in high-grade glioma in paraffin-embedded tissue collected from patients enrolled in the Mayo Clinic or North Central Cancer Treatment Group (NCCTG) high-grade glioma trials conducted since 1979. - To evaluate alterations of specific chromosomes and chromosomal regions including 7, 9p, 10p, 10q, 13q, 17p, 17q, 19q, 22q, X, and Y using PCR analysis of microsatellite repeats and FISH. - To determine DNA ploidy by flow cytometric analysis. - To examine various markers of cellular proliferation and cellular function including flow cytometric determination of %S-phase, %G2M, and immunohistochemical evaluation of PCNA, Ki-67, and p53. - To evaluate additional markers identified by the Glioma Markers Network. - To compare the incidence of markers in the major histologic subtypes (anaplastic astrocytoma [AA], anaplastic oligoastrocytoma [AOA], glioblastoma multiforme [GBM]) and to assess their correlation in the total group, as well as within each of these subtypes. - To compare the ploidy determinations by FISH and flow cytometry. OUTLINE: Paraffin-embedded tissue and peripheral blood samples, previously or currently collected from clinical trials participants at the time she/he enrolled in the trial, are evaluated for as many markers as possible, changes in cytogenic and molecular genetic tumor markers, frequency distributions of all tumor markers and histological and clinical variables by polymerase chain reaction, IHC, flow cytometry, and FISH analysis.
