Brief Summary:

RATIONALE: COL-3 may stop the growth of brain tumors by stopping blood flow to the tumor.

PURPOSE: Phase I/II trial to study the effectiveness of COL-3 in treating patients who have progressive or recurrent brain tumors following radiation therapy or chemotherapy.

Condition or disease Intervention/treatment Phase
Brain and Central Nervous System Tumors Drug: incyclinide Phase 1 Phase 2

Detailed Description:


  • Determine the maximum tolerated dose, dose limiting toxicity, and safety profile of oral COL-3 alone or when combined with anticonvulsants known to be metabolized by CYP450 in patients with progressive or recurrent high grade anaplastic astrocytoma, anaplastic oligodendroglioma, or glioblastoma multiforme.
  • Define the pharmacokinetics and pharmacodynamics of COL-3 on this schedule and determine the effects of hepatic enzyme inducing drugs, such as anticonvulsants, on the pharmacokinetics.
  • Determine the response rate, disease free survival, and survival in patients treated with this regimen.

OUTLINE: This is a dose-escalation, multicenter study of COL-3. Patients are stratified by anticonvulsant (anticonvulsants that cause induction of CYP450 vs anticonvulsants that cause modest or no induction of CYP450 or no anticonvulsant).

  • Phase I: Patients receive oral COL-3 daily. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of COL-3 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity.

  • Phase II: Patients receive oral COL-3 daily at the MTD from the phase I portion of this study.

Patients are followed every 2 months until death.

PROJECTED ACCRUAL: A total of 15-18 patients will be accrued for phase I of the study and a total of 35 patients will be accrued for phase II of the study at a rate of 3 patients per month.
