Official Title: Phase I/II Trial of Oral Erlotinib (Tarceva, OSI-774) for Treatment of Relapsed/Refractory Glioblastoma Multiforme and Anaplastic Astrocytoma
Brief Summary: This study will offer a safe treatment for patients with relapsing recurring glioblastoma (GBM) or anaplastic astrocytoma (AA). The trial will test the hypothesis that Erlotinib (Tarceva, OSI-774) can be safely used up to a dose of 150 mg two times a day for 12 months to ultimately enhance survival of patients with relapsed/refractory GBM/AA. Correlation of response to Tarceva with particular genetic alterations including epidermal growth factor receptor variant type III (EGFRvIII) amplification and phosphatase and tensin homolog (mutated in multiple advanced cancers 1) (PTEN) loss will be studied.
