OBJECTIVES:
- Determine the maximum tolerated dose, recommended phase II dose, and associated toxic effects of BMS-247550 in patients with advanced solid tumors.
- Determine the pharmacokinetic and pharmacodynamic relationship of this treatment regimen in these patients.
- Assess the extent of microtubule bundle and mitotic aster formation and cell cycle kinetics in peripheral blood mononuclear cells in these patients treated with this regimen.
- Determine any evidence of antitumor activity of this treatment regimen in these patients.
- Evaluate the relationship between tumor response and the occurrence of mutation in the class 1 isotype of B-tubulin and B-tubulin isotype distribution in patients with advanced or recurrent solid tumors, ovarian cancer, or breast cancer treated with this regimen.
- Investigate Multi-Drug Resistance Gene (MDR1), Multidrug Resistance-associated Protein (MRP) Gene, and canalicular multispecific organic anion transporter 1(cMOAT) messenger ribonucleic acid (mRNA) and protein expression as prognosticators of tumor response in these patients treated with this regimen.
- Determine the relationship between stathmin expression and phosphorylation status as a function of response in these patients treated with this regimen.
- Correlate the expression of proapoptotic (p53, bax, bad, and bid) and antiapoptotic (survivin, inhibitors of apoptotic proteins, bcl-2, and bcl-x) proteins in tumor samples and/or ascites with response and clinical outcome in these patients treated with this regimen.
OUTLINE: This is a dose-escalation, multicenter study.
- Part I: Patients with advanced solid tumors receive BMS-247550 IV over 1 hour every 3 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of BMS-247550 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
- Part II: Patients with ovarian, breast, or other cancer receive BMS-247550 as in the part I portion of the study at the MTD. Treatment continues in the absence of disease progression or unacceptable toxicity.
Patients are followed at 2 months.
PROJECTED ACCRUAL: Approximately 42-66 patients will be accrued for this study within 12-16 months.
