Study of Platelet Derived Growth Factor Receptor (PDGFR) in Recurrent Malignant Gliomas



The purpose of this study is to determine the survival, disease response, and side effects of Tasigna® (nilotinib) in patients who have malignant gliomas and are positive for Platelet Derived Growth Factor Receptor (PDGFR) amplification. This study is designed to test the hypothesis that patients with malignant gliomas with PDGFR amplification are sensitive to PDGFR kinase inhibitors.

    Trial Purpose

    The purpose of this study is to determine the survival, disease response, and side effects
    of Tasigna (nilotinib) in patients who have malignant gliomas and are positive for Platelet
    Derived Growth Factor Receptor (PDGFR) amplification. This study is designed to test the
    hypothesis that patients with malignant gliomas with PDGFR amplification are sensitive to
    PDGFR kinase inhibitors.

    Detailed Description

    Malignant gliomas (MG), including anaplastic gliomas (AG) and glioblastoma (GBM), are the
    most common primary brain tumor. Standard of care (surgery, radiotherapy, and temozolomide
    at initial diagnosis) results in a median survival of only 14 months. For patients with
    recurrent disease, conventional chemotherapy is generally ineffective with response rates
    <20%. Clearly there is need for improved treatments. Recent genome-wide studies have
    confirmed that GBM is a heterogeneous group of diseases that can be subclassified by shared
    genetic aberrations. The implication is that, in part, the underlying genetics may determine
    responsiveness to treatments and thus allow us to personalize therapy.

    This is an, open-label, non-randomized, phase II study with oral nilotinib in adult patients
    with biomarker-enriched, recurrent malignant gliomas who have developed tumor progression
    after standard therapy. Patients will be treated with oral nilotinib (starting with the
    labeled dose of 400 mg) daily until disease progression or intolerance. One cycle is defined
    as 28 days.

    Approximately 50 evaluable patients will be enrolled in this study, with 32 (grade IV) and
    18 (grade III) in separate arms.

    All patients will undergo clinical evaluation after each 28-day cycle. Neuroimaging studies
    (MRI) will be performed at baseline, 4 weeks, 8 weeks and then after every 2 cycles (8
    weeks). If a contraindication for MRI's exists, patients will undergo contrast-enhanced CT
    scans. Laboratory tests will be obtained weekly during the first 4 weeks, and then on days 1
    and 15 of all subsequent cycles. Patients will remain on study medication unless they
    develop tumor progression or unacceptable toxicity.

    lower-grade glioma. Pathology will be read centrally to confirm diagnosis.

    - Documentation of amplified PDGFRA by fluorescent in-situ hybridization (FISH),
    colorimetric in-situ hybridization (CISH), or quantitative PCR from tumor tissue (=>3
    copy number). Availability of unstained paraffin slides or the paraffin block of
    pretreatment baseline tissue is required for eligibility and for molecular analysis
    and would help to identify molecular predictors of outcome (all patients).

    - Participants must have a Karnofsky Performance Status (KPS) 60.

    steroid dose is increased between the date of imaging and registration, a new
    baseline MRI/CT is required. The same type of scan, i.e., MRI or CT must be used
    throughout the period of protocol treatment for tumor measurement. A patient who
    develops a contraindication to undergo an MRI scan during study treatment may remain
    on study and undergo contrast enhanced CT scans.

    greater than or equal to 60 days from the completion of radiation therapy to study

    - Subjects must have recovered from the toxic effects of prior therapy. Residual
    toxicity from any previous treatment must be Grade 1.

    investigational agent, 28 days from prior cytotoxic therapy (except 23 days from
    prior temozolomide, 14 days from vincristine, 42 days from nitrosoureas, 21 days from
    procarbazine administration), and 7 days for non-cytotoxic agents, e.g., interferon,
    tamoxifen, thalidomide, cis-retinoic acid, etc. (radiosensitizer does not count).
