A Phase I Scientific Exploratory Study of Epothilone B Analog in Patients With Solid Tumors and Gynecological Malignancies

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so
they stop growing or die.

PURPOSE: Phase I trial to study the effectiveness of BMS-247550 in treating patients who have
metastatic, recurrent, or locally advanced, ovarian cancer, breast cancer, or metastatic or
unresectable solid tumors.

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.
