Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy, such as tetra-O-methyl nordihydroguaiaretic acid (EM-1421), work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase I/II trial is studying the side effects and best dose of EM-1421 and to see how well it works in treating patients with recurrent high-grade glioma.

- type
- ACTIVE_COMPARATOR
- label
- With Enzyme-inducing antiseizure drugs (+EIASD)
- description
- subjects on the +EIASD treatment arm were taking one of these antiseizure drugs: phenytoin, carbamazepine, phenobarbital, primidone and oxcarbazepine. Subjects will take terameprocol for 5 consecutive days each month by IV. Starting dose is 750mg/day. Dose escalation is 750, 1100, 1700, 2200, 3000, 4000, 5300, 7000, and 9300. NO intrasubject dose escalation. PK (pharmacological study) data will be collected on day one of cycle one infusion

- ACTIVE_COMPARATOR
- label
- With Non enzyme-inducing antiseizure drugs (-EIASD)
- description
- Subjects in the -EIASD group were either not being treated with antiseizure drugs or were taking ones that did not significantly induce hepatic enzymes such as gabapentin, lamotrigine, valproic acid, levetiracetam, tiagabine, topiramate, zonisamide and felbamate. Subjects will take terameprocol for 5 consecutive days each month by IV. Starting dose is 750mg/day. Dose escalation is 750, 1100, 1700, 2200, 3000, 4000, 5300, 7000, and 9300. NO intrasubject dose escalation. PK (pharmacological study) data will be collected on day one of cycle one infusion
