简要总结
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.
详细描述
OBJECTIVES:
Primary
- Determine the maximum tolerated dose (MTD) of tetra-O-methyl nordihydroguaiaretic acid (EM-1421) in patients with recurrent high-grade glioma. (Phase I)
- Determine the response rate in patients treated with EM-1421 administered at the MTD. (Phase II)
Secondary
- Describe the pharmacokinetics of EM-1421 in these patients. (Phase I)
- Determine the effects of hepatic enzyme-inducing anticonvulsants on the pharmacokinetic profile of EM-1421 in these patients. (Phase I)
- Determine the toxicity of this drug in these patients. (Phase I)
- Assess the tolerability of this drug in these patients. (Phase I)
- Assess the antitumor activity of this drug, in terms of overall survival. (Phase I)
- Assess the overall survival of these patients. (Phase II)
- Assess the safety and tolerability of EM-1421 given at the MTD in these patients. (Phase II)

研究组 & 干预措施
With Enzyme-inducing antiseizure drugs (+EIASD)
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

干预措施: pharmacological study (Other)
With Non enzyme-inducing antiseizure drugs (-EIASD)
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.

结局指标
主要结局
Maximum Tolerated Dose (Phase I)
时间窗: first 30 days of treatment
Using the PEG formulation pts both with and without enzyme inducing antiseizure drugs (EIASD) were treated at Doses 750, 1100, 1700, 2200 mg/day for five days = 28pts Using the PEG free formulation pts with and without EIASD) were treated at 1700 and 2200 mg/day X 5 days = 8pgs
Maximum Tolerated Dose (Phase I) - Dose Limiting Toxicity (DLT)
时间窗: First 30 days
Dose limiting Toxicity defined as: Treatment related events; absolute neutrophil count \</=500 /mm3; platelets count \</=25,000/mm3; febrile neutropenia; any grade 3 or 4 non-hematologic toxicity; any delay in starting subsequent course of treatment for \>14 days because of incomplete recovery from treatment
