I. Determine the toxicity profile, dose-limiting toxicity, and maximum tolerated dose of flavopiridol (alvocidib) as consolidation chemotherapy after cytoreduction chemotherapy in patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.
I. Determine the pharmacokinetics and cellular pharmacodynamics of flavopiridol in these patients.
II. Determine the complete response (CR) and overall response rate (CR and partial response) of patients treated with flavopiridol.
OUTLINE: This is a dose-escalation study. Patients receive alvocidib intravenously (IV) over 30 minutes (loading dose), followed by alvocidib IV over 4 hours on days 1, 8, and 15.
Treatment repeats every 5 weeks 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 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. A total of 12 patients are treated at the MTD (i.e., recommended phase II dose). Patients undergo blood collection at baseline and periodically during study for pharmacokinetic and cytokine studies (levels of tumor necrosis factor-alpha, interleukin [IL]-6, -11, and -16) by enzyme-linked immunosorbent assay (ELISA). Interphase cytogenetics, p53 mutational status, p53/ATM function, V_H mutational status, zeta-chain-associated protein kinase 70 (ZAP-70) overexpression, and single nucleotide polymorphisms are also examined.
After completion of study treatment, patients are followed at 2 months and then every 3 months for 5 years.

|Official Title:||A Phase I Dose-Escalation Study of Flavopiridol (NSC 649890) Administered as a 30 Minute Loading Dose Followed by a 4-Hour Infusion in Patients With B-Cell Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) Following Cytoreduction With Chemotherapy|
|Study Start Date :||September 2006|
|Actual Primary Completion Date :||November 2012|
Experimental: Treatment (chemotherapy)
Patients receive alvocidib IV over 30 minutes (loading dose), followed by alvocidib IV over 4 hours on days 1, 8, and 15. Treatment repeats every 5 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity.

- Toxicity profile of alvocidib administered as a 30 minute loading dose followed by a 4-hour infusion once weekly for 3 consecutive weeks every 5 weeks as consolidation therapy following cytoreduction chemotherapy [ Time Frame: Day 1, every 2 courses, at 2 months and then every 3 months for 5 years after completion of study treatment ]Assessed utilizing the NCI Common Terminology Criteria for Adverse Events version 3.0.
- Dose-limiting toxicity of alvocidib as consolidation chemotherapy after cytoreduction chemotherapy in patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma [ Time Frame: Course 1 ]The National Cancer Institute Common Toxicity Criteria version 3.0 will be used to characterize toxicity. If no patients experience dose-limiting toxicity, dose escalation will occur. If 1 patient has a dose limiting toxicity, 3 additional patients will be enrolled at that dose. If fewer than 2 of 6 patients experiences dose limiting toxicity, then the next highest dose level will be used for the subsequent cohort of 3 patients. If at any dose level two or more of the six patients experience a dose limiting toxicity, 3 additional patients will be treated at the previous dose level.
- Pharmacokinetics and cellular pharmacodynamics of alvocidib administered in this schedule [ Time Frame: Baseline and day 1 ]Cytokine studies will be examined by standard ELISA assays to determine if increase IL-6 correlates with hypotension, hypoxemia, and tachycardia observed following treatment and to identify the source of production of this cytokine. We will examine interphase cytogenetics, p53 mutational status, p53/ATM functional assay, VH mutational status, and ZAP-70 over-expression.
- Complete response (CR) and overall response rate (CR and partial response) of alvocidib in patients with previously-treated CLL [ Time Frame: Baseline, every 2 courses, at 2 months and then every 3 months for 5 years after completion of study treatment ]Criteria for response will utilize the Revised National Cancer Institute-sponsored Working Group Guidelines.
