Primary Outcome Measures:
  • The Progression Free Survival-6m rate defined as the proportion of subjects that are alive and progression-free at 6-months from the date of first dosing based on RECIST 1.1. [ Time Frame: 6 months ]
    The Progression Free Survival-6m rate defined as the proportion of subjects that are alive and progression-free at 6-months from the date of first dosing based on RECIST 1.1. PFS-6m rate will be estimated from Kaplan-Meier (K-M) product-limit estimate of PFS.

Enrollment: 8
Study Start Date: May 2012
Study Completion Date: February 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: E7016 plus TMZ Drug: TMZ
TMZ (at 150 mg/m2) will be administered orally according to the instructions on the product label, on Days 1 through 5 of the same 28-day cycle as E7016. TMZ capsules should be taken immediately after E7016. No food or drink intake, except water, will be allowed for 2 hours before or after administration.
Drug: E7016

E7016 capsules will be administered in the morning after at least a 2-hour fast. Subjects will be instructed not to eat or drink anything except water in the 2 hours prior and 2 hours after drug administration. Subjects will record the time at which they ate.

For the Single-Dose PK Period, 320 mg of E7016 will be administered once on Day -2. For the Multiple-Dose Treatment Cycle(s), 320 mg E7016 will be administered QD on Days 1 through 7 of each 28-day cycle.

If there is only one target lesion and it is a non-lymph node, it should have a longest diameter of greater than or equal to 1.5 cm.
    • Lesions that have had external beam radiotherapy (EBRT) or loco-regional therapies such as radiofrequency (RF) ablation must show evidence of progressive disease based on RECIST 1.1 to be deemed a target lesion.
  8. Subjects with brain metastases will be eligible under the following conditions:

    • have undergone complete surgical excision and are more than 1 month post-surgery with no radiographic evidence of disease recurrence in the brain or
    • have undergone stereotactic radio surgery (gamma knife procedure or radiotherapy ) and are more than 1 month post procedure and with no radiographic evidence of disease progression in the brain and
    • are asymptomatic and
    • discontinued corticosteroid treatment and/or anticonvulsive therapy at least 1 week prior to Cycle 1, Day 1
  9. Adequate renal function indicated by serum creatinine less than 1.5 mg/dL or calculated creatinine clearance greter than 50 mL/minute per Cockroft Gault formula
  10. Adequate bone marrow reserve:

    • Absolute neutrophil count (ANC) greater than or equal to 1500/mm^3 (greater than or equal to 1.5 x 10^3/mL)
    • Platelets greater than or equal to 100,000/mm^3 (without transfusion)
    • Hemoglobin greater than or equal to 10 g/dL (less than 10.0 g/dL acceptable if corrected by growth factor or transfusion)
  11. Adequate liver function:

    • Bilirubin less than or equal to 1.5 x the upper limit of normal (ULN) except for unconjugated hyperbilirubinemia of Gilbert's syndrome
    • Alkaline phosphatase, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) less than or equal to 3 times ULN (less than or equal to 5 x ULN if subject has liver metastases)
  12. Left ventricular ejection fraction (LVEF) greater than 50% on echocardiography or multiple-gated acquisition (MUGA) scanning
  13. Females must not be lactating or pregnant at screening or baseline (as documented by a negative beta-human chorionic gonadotropin [B-hCG] test with a minimum sensitivity of 25 IU/L or equivalent units of B-hCG). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug. All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing). Females of childbearing potential must not have had unprotected sexual intercourse within 30 days prior to study entry and must agree to use a highly effective method of contraception (e.g., total abstinence, an intrauterine device, a double-barrier method [such as condom plus diaphragm with spermicide], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double-barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. Females who are using hormonal contraceptives must have been on a stable dose of the same hormonal contraceptive product for at least 4 weeks prior to dosing and must continue to use the same contraceptive during the study and for 30 days after study drug discontinuation.
  14. Male subjects must have had a successful vasectomy (confirmed azoospermia) or they and their female partners must meet the criteria above (i.e., not of childbearing potential or practicing highly effective contraception throughout the study period and for 30 days after study drug discontinuation).
