A Phase I/II Study of an Oral Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI), ZD 1839 (Iressa), [NSC #715055] With Radiation Therapy in Glioblastoma Multiforme
PRIMARY OBJECTIVES:
I. To identify the maximum tolerated dose of ZD 1839 (gefitinib) when given concurrently
with cranial radiotherapy.
II. To determine if ZD 1839, given orally on a daily basis starting at the time of
conventional radiation therapy (RT), may improve the overall survival of adults with
newly-diagnosed supratentorial glioblastoma multiforme, compared with historical controls,
stratifying by epidermal growth factor receptor (EGFR) status.
III. To determine, in a multi-institutional setting, the feasibility and toxicity of
prescribing ZD 1839.
SECONDARY OBJECTIVES:
I. Whether ZD 1839 also improves progression-free survival in these patients.
OUTLINE: This is a phase I, dose-escalation study of gefitinib followed by a phase II study.
Patients receive gefitinib orally (PO) once daily (QD) for 7 weeks. Beginning 1 week after
initiation of gefitinib, patients undergo radiation therapy QD 5 days a week for 6 weeks.
Treatment with gefitinib continues for up to 18 months in the absence of disease progression
or unacceptable toxicity.
After completion of study treatment, patients are followed up every 4 months for 1 year,
every 6 months for 2 years, and annually thereafter.
