Paclitaxel and GEM 231 in Treating Patients With Recurrent or Refractory Solid Tumors

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of paclitaxel and GEM 231 in treating patients who have recurrent or refractory solid tumors.

OBJECTIVES: I. Determine the safety and maximum tolerated dose of GEM 231 and paclitaxel in patients with recurrent or refractory solid tumors. II. Determine any preliminary antitumor activity of this regimen in these patients.

OUTLINE: This is a dose escalation study of GEM 231. Patients receive paclitaxel IV over 3 hours on day 1, immediately followed by GEM 231 over 2 hours on days 1, 4, 8, 11, 15, and 18. Treatment continues every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients are treated with one of two doses of paclitaxel and escalating doses of GEM 231 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 2 of 6 patients experience dose limiting toxicity. Patients are followed monthly for 3 months.

PROJECTED ACCRUAL: A maximum of 1 patient will be accrued per week for this study until the maximum tolerated dose is reached.
