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
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
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.
