Study of Platelet Derived Growth Factor Receptor (PDGFR) in Recurrent Malignant Gliomas
a study on Glioma
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.
A Phase II Study of PDGFR Kinase Inhibitor in Biomarker-Enriched Recurrent Malignant Gliomas
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.

- INR < 1.5
- PTT within institution's normal range, unless receiving therapeutic low molecular weight heparin
- Female patients of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Male and female patients of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug.
- Participants must have an unequivocal progression by magnetic resonance imaging (MRI)or computed tomography (CT) scan. A scan must be performed within 14 days prior to registration and on a steroid dose that has been stable for at least 5 days. If the 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.
- Patients must have failed prior radiation therapy and must have an interval of greater than or equal to 60 days from the completion of radiation therapy to study entry.
