Brief Summary:

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxyurea, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving imatinib mesylate together with hydroxyurea may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving imatinib mesylate together with hydroxyurea works in treating patients with recurrent or progressive meningioma.

Condition or disease	Intervention/treatment	Phase
Glioblastoma; Gliosarcoma	Drug: hydroxyurea; Drug: imatinib mesylate	Phase 2

Detailed Description:

OBJECTIVES:

Primary

• Evaluate the activity of imatinib mesylate and hydroxyurea, as measured by 6-month progression-free survival, in patients with recurrent or progressive meningioma.

Secondary

• Evaluate the progression-free survival (PFS)
• Overall survival (OS),
• Objective response rate among patients treated with this regimen.

OUTLINE: This is an open-label study.

Patients receive oral imatinib mesylate once or twice daily and oral hydroxyurea twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 21 patients will be accrued for this study.

Intervention/treatment

Experimental: Imatinib mesylate+hydroxyurea; All patients receive imatinib mesylate and hydroxyurea orally on a daily, continuous basis. Dosing of imatinib mesylate is adjusted for patients who are also receiving p450-inducing anti-epileptic drugs.

Drug: hydroxyurea; Hydroxyurea is administered orally twice a day. The dose will be set at 500 mg twice a day for all patients. If vomiting occurs not additional trial medication should be taken that day in an effort to replace the material that has been vomited. It is recommended that patients take their prescribed hydroxyurea at the same time that they take their prescribed imatinib mesylate, however, a 30-60 minute interval between agents is acceptable, if required for practical or other compliance issues.; Other Names: Droxia; Hydrea; Hydroxycarbamide Drug: imatinib mesylate; Imatinib administered orally on daily, continuous basis. Imatinib doses of 400mg/600mg administered once daily, whereas daily doses of 800mg/greater administered as equally divided dose taken twice day. Dose for Imatinib: Patients receiving p450-inducing antiepileptic drugs:500mg twice day Patients not receiving p450-inducing antiepileptic drugs:400mg/day. If patients who were not on Cytochrome P450, family 3, subfamily A (CYP3A) enzyme-reducing anti-epileptic drug (EIAED) when originally enrolled must initiate CYP3A enzyme-inducing anti-epileptic drug while on study, study regimen will remain same for minimum of 2 wks before pt transitions to dosing as specified for patients on anti-epileptic drug. If patients originally enrolled must discontinue all EIAEDs while on study, in interest of patient safety, dosing of study regimen will transition to that of patients not on anti-epileptics immediately.; Other Name: Gleevec

Primary Outcome Measures :

1. Progression-free Survival at 6 Months [ Time Frame: From the date of study treatment initiation to the date of the first documented progression or death from any cause, whichever came first, assessed up to 69 months. For each participant, PFS was assessed at 6 months after treatment initiation. ]
   Percentage of participants surviving six months from the start of study treatment without progression of disease. PFS was defined as the time from the date of study treatment initiation to the date of the first documented progression according to the Macdonald criteria, or death due to any cause.

Secondary Outcome Measures :

1. Median Progression-free Survival (PFS) [ Time Frame: From the date of study treatment initiation to the date of the first documented progression or death from any cause, whichever came first, assessed up to 69 months. ]
   Time in months from the start of study treatment to the date of first progression according to Macdonald criteria, or to death due to any cause. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve.
2. Median Overall Survival (OS) [ Time Frame: From the date of study treatment initiation to the date of death from any cause, assessed up to 69 months. ]
   Time in months from the start of study treatment to date of death due to any cause. Patients alive at last follow-up are censored as of that follow-up date. Median OS was estimated using a Kaplan-Meier curve.
3. Objective Response Rate [ Time Frame: 69 Months ]
   Percentage of participants with an objective response (complete response or partial response). Per modified Macdonald criteria and assessed by MRI, complete response (CR) was the disappearance of all target lesions and partial response (PR) was a ≥50% decrease in the sum of the longest diameter of target lesions. Objective response = CR+PR.
