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.
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.

Three patients will be accrued to level 1. If no dose limiting toxicities are observed following completion of 4 weeks (2 cycles) of treatment then accrual to dose level 2 will proceed (patients must be evaluated prior to their cycle 3 treatment and this will be used to confirm DLTs). If a DLT is observed in one of the first 3 patients in a dose level, then accrual for that level will be expanded to 6 patients. Accrual will continue in this way until the MTD of nanoliposomal irinotecan with temozolomide 50mg/m2/day is determined. Two or more instances of DLT in a cohort of 6 patients will result in the preceding dose level being defined as the MTD. If two or more instances of DLT in a cohort of 6 patients occurs in dose level 1 then dose level -1 of nanoliposomal irinotecan will be investigated. After determination of the MTD, the final cohort will be expanded so that a total of 25 patients are treated on study. The final cohort will be treated at the MTD.

Determination of Maximum Tolerated Dose (MTD)
To evaluate the maximum tolerated dose of nanoliposomal irinotecan with continuous low-dose temozolomide for patients with recurrent glioblastoma.
Time frame: Every two weeks for 4 weeks
Response
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR."
Time frame: Every 2 months on study treatment then very 3 months once treatment has stopped, until progression of disease up to 2 years.
Survival Status of Participants Treated With Nanaliposomal Irinotecan With Continuous Low-dose Temozolomide in Patients With Recurrent Glioblastoma.
Time frame: Collected every 3 months once treatment has stopped, until progression of disease, up to 2 years.
Toxicities
Treatment emergent toxicities of nanoliposomal irinotecan with continuous low-dose temozolomide using CTCAE version 4.03, grades 2 through 4
Time frame: Baseline through 30 days post off study treatment
