Brief summary

Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. This phase I/II trial is studying the side effects and best dose of ixabepilone and how well it works in treating patients with recurrent glioma.

Detailed description

PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose of BMS-247550 when administered to adults with recurrent malignant gliomas, receiving (Group A) or not receiving (Group B) anticonvulsants known to be metabolized by the P450 hepatic enzyme complex. II. To describe the pharmacokinetics of this route of administration, measuring BMS-247550, and determine the effects of hepatic enzyme inducing drugs, such as anticonvulsants, on the pharmacokinetics. III. To determine the response rate of adult patients with recurrent glioma to BMS-247550 administered at the MTD. IV. To describe the toxicity associated with this regimen in adult patients with recurrent malignant gliomas. SECONDARY OBJECTIVES: I. To determine the percent of patients with 6 month progression free survival, duration of progression free survival and survival associated with this therapy in adult patients with recurrent malignant gliomas. OUTLINE: This is a phase I, dose-escalation, multicenter study followed by a phase II, safety and efficacy, multicenter study. For phase I only, patients are stratified according to cytochrome P450-inducing anticonvulsant use (yes vs no). Phase I: Patients receive ixabepilone IV over 1 hour on days 1-5. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3 patients receive escalating doses of ixabepilone until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 patients experience dose-limiting toxicity. Phase II: Once the MTD is determined, additional patients receive ixabepilone as above at the MTD. Patients are followed every 2 months. PROJECTED ACCRUAL: A minimum of 10-15 patients will be accrued for the phase I portion of this study. A total of 22-33 patients will be accrued for the phase II portion of this study within 4-6 months.

Recruitment details

Fifty-seven subjects were enrolled in the Phase 1 and Phase 2 between October 2002 and November 2005. Subjects were enrolled from outpatient medical clinics

Pre-assignment details

Please note that 4 subjects in Arm B (non-P450- 6.8mg/m2) were used in the analysis and total n for the Phase 2. Hence, 19 new subjects were accrued to the Phase 2 portion of the study at the 6.8mg/m2 dose level, but the 4 subjects already treated at 6.8gmg/m2 were included in Phase 2 analysis.

Population: 4 subjects from Group B (Phase 1) were included in Group 3 (Phase 2). Only those on non-anticonvulsants at the dose of 6.8mg/m2/day were treated in Phase 2. No subjects treated at the MTD for P450, as the accrual goal for phase 2 reached before MTD for p450 was determined. P450 MTD determined as 9.6mg/m2 per CRM after all enrollment of phase 2

Primary

Response Rate of Patients at the MTD

Complete Response: Complete disappearance of all tumor on MRI scan, off all glucocorticoids with stable/improving neurologic exam for min4 wks. Partial Response: Greater than or equal to 50% reduction in tumor size on volumetric MRI scan, on a stable/decreasing dose of glucocorticoids, with stable/improving neurologic examination for min 4 wks. Progressive Disease: Progressive neurologic abnormalities not explained by causes unrelated to tumor progression (e.g. anticonvulsant or corticosteroid toxicity, electrolyte abnormalities, hyperglycemia, etc.) or a greater than 25% increase in the volume of the tumor by MRI scan. If neurologic status deteriorates, on stable/increasing dose of steroids, or if new lesions appear on serial MRI, further study treatment will be discontinued. Stable Disease: A patient whose clinical status and MRI volumetrics do not meet the criteria for Complete Response, Partial Response or Progressive Disease.

Time frame: 3 years

Population: no objective responses observed. 19 patients treated at the MTD from during Phase 2 and 4 patients treated at the MTD during the Phase 1 nonP450 arm 2 were included in the response analysis.
