Study Details

Study Description

Brief Summary

The primary objectives of this study are to determine the maximal tolerated dose (MTD) of PAC-1 in combination with temozolomide in patients with high grade glioma: glioblastoma multiforme (GBM) or anaplastic astrocytoma after progression following standard first line therapy (Component 2), by evaluation of toxicity and tolerability.

Condition or Disease Intervention/Treatment Phase
  • Drug: PAC-1 Compound
Phase 1

Detailed Description

PAC-1 in combination with temozolomide (Component 2): after the MTD is established for single agent PAC-1 in Component 1, a modified-Fibonacci dose-escalation 3+3 design starts in Component 2, at a PAC-1 dose one level lower than the MTD of PAC-1 established in the single agent PAC-1 component (i.e., Component 1) and 150 mg/m2 dose of temozolomide given for the 5 days starting at day 8 of cycle 1 in cohorts of 3-6 patients. The combination cohort that reaches MTD will expanded to at least 9 patients, similar to the PAC-1 alone cohort at MTD. For all dose cohorts, pharmacokinetics of PAC-1 will be assessed following doses administered on days 1 and 11 of the first cycle. Temozolomide pharmacokinetics will be performed on Day 11 of the first cycle.

Arms and Interventions

Arm Intervention/Treatment
Experimental: PAC-1 in combination with temozolomide

Temozolomide (PO) will be dosed at 150 mg (adjusted for body size area [m2]) daily for 5 days starting on day 8 at cycle 1, and then for each successive cycle. In Component 2, the first PAC-1 dose will be 1 dose level lower than the PAC-1 MTD established in Component 1, and the maximum dose will not exceed 450 mg. PAC-1 will be taken in the morning on days 1-21 in each 28-day cycle.

    Primary Outcome Measures

    1. Maximum Tolerated Dose (MTD) [During treatment cycle 1 (first 28 days)]

      MTD, defined as the highest tolerated dose of PAC-1 tested in combination with temozolomide in patients with high grade glioma.

    Secondary Outcome Measures

    1. Adverse Effects [Up to 30 days post final dose]

      Toxicity will be graded using the Common Terminology Criteria for Adverse Events version 4 (CTCAE v4)

    2. Disease Response [Through study completion, an average of one year]

      Disease response will be assessed by RANO criteria.
