Drugs used in chemotherapy, such as flavopiridol, cytarabine, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving a new schedule of more than one drug (combination chemotherapy) may kill more cancer cells. This phase I trial is studying the side effects, best dose, and best schedule for flavopiridol when given together with cytarabine and mitoxantrone in treating patients with relapsed or refractory acute leukemia.

Clinical Details

Official title: Phase I Study of a Pharmacologically Derived Hybrid Bolus-Infusion Schedule of Flavopiridol (NSC 649890, IND 46,211) Given in Timed Sequential Combination With Cytosine Arabinoside (Ara-C) and Mitoxantrone for Adults With Relapsed and Refractory Acute Leukemias

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Maximum tolerated dose determined by dose-limiting toxicities graded according to NCI-CTC version 3.0

Detailed description: OBJECTIVES: I. Determine the toxicities of escalating doses of flavopiridol administered by "hybrid" bolus-infusion schedule and given in timed sequence with cytarabine and mitoxantrone hydrochloride in patients with refractory or relapsed acute leukemia. II. Determine the incidence of clinical response in patients treated with this regimen. OUTLINE: This is a dose-escalation study of flavopiridol. Patients receive flavopiridol IV over 30 minutes on days 1, 2, and 3. Patients receive cytarabine IV continuously over 72 hours beginning on day 6 and mitoxantrone hydrochloride IV over 60-120 minutes on day 9. Treatment repeats every 35-63 days for up to 2 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of flavopiridol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 or 2 of 6 patients experience dose-limiting toxicity. Serum and bone marrow samples are collected at baseline, during, and after completion of treatment for future studies. Flavopiridol levels are measured at baseline and on days 1-3 for pharmacokinetics.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
