Phase I/II Trial of Oral Erlotinib (Tarceva, OSI-774) for Treatment of Relapsed/Refractory Glioblastoma Multiforme and Anaplastic Astrocytoma
In Brief
A Phase 2 clinical trial evaluating Erlotinib for Glioblastoma Multiforme and Anaplastic Astrocytoma. Completed, enrolled 11 participants across 1 site.
Detailed 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.

Timeline
Interventions
Tarceva®: Will be given at a starting dose of 150mg QD dose for the first cycle which is 28 days. This will be followed by 14 days of 100mg PO on a bid schedule and 150mg PO on a bid schedule for the final 14 days of the second cycle. Assuming no dose limiting toxicity, 150 mg PO tid will be continued for up to 10 more cycles. This is an outpatient regimen, in which the drug is admininistered orally. Tumor response will be assessed after every 2nd treatment cycle. Patients may receive a maximum of 12 cycles of treatment under this research protocol.
