Phase I/II trial to study the effectiveness of erlotinib in treating patients who have recurrent malignant glioma or recurrent or progressive meningioma. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.
OBJECTIVES: Phase 1 I. Determine the maximum tolerated dose of erlotinib in patients with recurrent malignant glioma or recurrent or progressive meningioma. II. Determine the safety profile of this drug in these patients. III. Determine the pharmacokinetics of this drug in these patients. Phase 2 I. Determine the 6-month progression-free survival (recurrent malignant glioma) II.12-month survival of patients treated with this drug (stable glioblastoma post radiation therapy) Phase 2 - Secondary Recurrent Malignant Glioma I. Objective Tumor Response rate associated with erlotinib therapy in recurrent or progressive malignant glioma. III. 12-month survival of patients treated with this drug Determine the safety profile of this drug in these patients. IV.. Determine the pharmacokinetics of this drug in these patients OUTLINE: This is a dose-escalation, multicenter study. Patients are stratified according to study phase (I vs II), concurrent enzyme-inducing antiepileptic drugs (EIAEDs) (yes vs no), histology (recurrent GBM vs recurrent anaplastic glioma vs recurrent meningioma vs stable GBM), preoperative candidacy (yes vs no), and concurrent steroids (yes vs no). Phase I: Patients concurrently receiving EIAEDs receive oral erlotinib once daily. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of erlotinib until the maximum tolerated dose (MTD) is determined. The MTD is the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Phase II: Once the MTD is determined, additional patients concurrently receiving EIAEDs are treated with erlotinib as above at the phase II dose. Patients not concurrently receiving EIAEDs are treated with erlotinib as above at a predetermined dose. Patients are followed for survival.

Number of Dose Limiting Toxicity (DLT) Each Dose Level Phase I
DLT Definition: any grade 3 thrombocytopenia and grade 4 anemia and neutropenia; any non-hematologic grade 3 toxicity; failure to recover from toxicities to be eligible for re-treatment with erlotinib within 2 weeks of the last dose of erlotinib.
Time frame: 28 days
Define Maximum Tolerated Dose (MTD) of Erlotinib by Phase 1 Cohorts
standard 3+3 dose escalation design 3 patients in each dose level, observed for 28 days before enrollment to next level. if none of the patients experienced DLT dose escalated, if 1 of 3 experienced DLT 3 more enrolled at that level, if none of the 3 additional pts had DLT escalate to next level, if one or more of the additional pts experienced DLT, the MTD was exceeded and 3 more patients were treated at the next lower dose (if only 3 pts treated at the lower dose). The MTD is the dose at which 0/3 or 1/6 patients have experienced a DLT with the next higher dose having at least 2/3 or 2/6 patients encountering DLT.
Time frame: cycle 1 - 28 days
6 Months Progression-free Survival in Recurrent Malignant Gliomas (Phase II)
Progression: 25% increase in the sum of products of all measurable lesions over smallest sum observed (over BL if no decrease), OR clear worsening of any evaluable disease, OR appearance of any new lesion/site, OR failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to this cancer).
Time frame: 6 months

1 Year Survival - Phase II Newly Diagnosed GBM Post RT
12 month survival for newly diagnosed stable GBM post RT treated with erlotinib post RT
Time frame: At 1 year
Overall Survival Newly Diagnosed GBM Post RT
Overall Survival defined as Time from Start of treatment to time of death due to any cause
Time frame: 2 years
Response Rate (Complete or Partial Response) Graded Using Modified RECIST Criteria Phase II
Measurable: Bidimensionally measurable lesions w/ clearly defined margins by MRI Evaluable: Unidimensionally measurable lesions, masses w/margins not clearly defined. Complete Response (CR): Complete disappearance of all measurable/evaluable disease. No new lesions. No evidence of non-evaluable disease. Patients on minimal/no steroids. Partial Response (PR): \>/= to 50% decrease under baseline in the sum of products of perpendicular diameters of all measurable lesions. No progression of evaluable disease. Responders must be on same/decreasing doses of dexamethasone. Stable/No Response: Does not qualify for CR, PR, or progression. Progression: 25% increase in the sum of products of all measurable lesions over smallest sum observed (over BL if no decrease), OR clear worsening of any evaluable disease, OR appearance of any new lesion/site, OR failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to this cancer).
