About
New treatments are greatly needed for patients with recurrent glioblastoma. Metronomic temozolomide is a standard treatment option but has, at best, modest activity. The nanoliposomal irinotecan may be much more active than the parent compound irinotecan since nanoliposomal irinotecan's ability to cross the blood brain barrier is improved. This phase I study will establish the MTD of the combination of nanoliposomal irinotecan in combination with temozolomide safety and preliminary clinical efficacy of the combination of nanoliposomal irinotecan and metronomic temozolomide.
Full description
1.1 Primary Objective 1.1.1. To evaluate the maximum tolerated dose of nanoliposomal irinotecan with continuous low-dose temozolomide for patients with recurrent glioblastoma.
1.1.2 To assess the preliminary response rate and progression free survival of nanaliposomal irinotecan with continuous low-dose temozolomide in patients with recurrent glioblastoma.
1.2 Secondary Objectives 1.2.1 To evaluate the safety of nanoliposomal irinotecan with continuous low-dose temozolomide.

Progression or recurrence after at least one line of therapy. Patient must have received temozolomide and radiation but it is not required that they were given concurrently.
Age >18 years
Karnofsky performance score > 60
Life expectancy >12 weeks as noted by treating investigator
Laboratory results requirements
Not pregnant and not nursing. Women of child bearing potential must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 7 days prior to Day 1 of treatment. Post-menopausal women (surgical menopause or lack of menses >12 months) do not need to have a pregnancy test, please document status.
Confirmation of informed consent.
Men and women of childbearing potential enrolled in this study must agree to use adequate barrier birth control measures during the course of the study and for at least 2 months after the last treatment on study.
Recovered (< grade 1) from clinically significant effects of any prior surgery, radiotherapy or other anti-neoplastic therapy, except alopecia or hematological laboratory values
Stable corticosteroid dose at least 7 days prior to day 1
Patients must have assessable (measurable) disease at baseline by brain MRI. Must be contrast enhancing. The tumor size will be measured in millimeters and is the largest cross-sectional area using perpendicular measurements of contrast enhancing abnormality.
Patient must be able to tolerate brain MRI with contrast
