Clinical Trial Summary

RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase II trial is studying how well erlotinib works in treating patients with recurrent glioblastoma multiforme or gliosarcoma.


Clinical Trial Description

OBJECTIVES:

Primary

- Determine the objective response rate in patients with recurrent epidermal growth factor receptor (EGFR)-positive and PTEN wild-type glioblastoma multiforme or gliosarcoma treated with erlotinib hydrochloride.

Secondary

- Assess the response rate in patients who also EGFRVIII mutant and PTEN wild type glioblastoma multiforme or gliosarcoma.

- Determine the progression-free survival of patients treated with this drug.

OUTLINE: This is an open-label study. Patients are stratified according to concurrent use of enzyme-inducing antiepileptic drugs (EIAEDs) (yes vs no).

Patients receive oral erlotinib hydrochloride once daily on days 1-28. Treatment repeats every 4 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity. Some patients may receive additional erlotinib hydrochloride after 1 year at their physician's discretion.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study. ;
