Phase I Trial of Gemcitabine Hydrochloride and Alvocidib in Solid Tumors: Dose Finding and Safety Evaluation

This phase I trial is studying the side effects and best dose of gemcitabine hydrochloride and alvocidib in treating patients with solid tumors. Drugs used in chemotherapy, such as gemcitabine hydrochloride and alvocidib, 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

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose of gemcitabine and flavopiridol in patients with solid tumors.

SECONDARY OBJECTIVES:

I. Determine the safety profile and toxic effects of this regimen in these patients.

II. Determine the pharmacokinetics of flavopiridol with and without gemcitabine in these patients.

III. Determine, using pharmacodynamic assays, the activity of flavopiridol as a cdk inhibitor in these patients.

IV. Determine, using pharmacodynamic assays, the markers of this regimen in these patients.
