Flavopiridol in Treating Patients With Refractory Cancer

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 flavopiridol in treating patients who have refractory cancer.

OBJECTIVES: I. Determine the dose-limiting toxicity and maximum tolerated dose of flavopiridol in patients with refractory solid tumors or lymphoma. 2. Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is a dose-escalation study. Patients receive flavopiridol IV over 1 hour on day 1. Treatment continues every 3 weeks in the absence of disease progression. A cohort of 3-6 patients receives treatment at each dose level of flavopiridol. If dose-limiting toxicity (DLT) occurs in no more than 1 of 6 patients, subsequent cohorts of 6 patients each receive escalating doses of drug on the same schedule. Intrapatient dose escalation to the next level is permitted in the absence of DLT.

PROJECTED ACCRUAL: Approximately 36 patients will be accrued for this study within 27 months.

Eligibility Criteria:
DISEASE CHARACTERISTICS: Histologically proven refractory solid tumor or lymphoma requiring systemic therapy No standard therapeutic options exist Prostate cancer patients: Tumor progression during blockade of testicular and adrenal androgen required PSA elevation on 2 consecutive blood samples, 2 weeks apart Serum testosterone concentrations in the castrate range Leuprolide or other gonadotropin-releasing hormone (GnRH) analogs maintained if no prior orchiectomy No CNS neoplasms
