Study Description

Brief Summary

This phase I trial studies the side effects and best dose of lenalidomide when given together with alvocidib in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma. Lenalidomide may stop the growth of leukemia or lymphoma by blocking blood flow to the cancer. Alvocidib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving lenalidomide together with alvocidib may kill more cancer cells.

Detailed Description

PRIMARY OBJECTIVES:

To determine the maximum tolerated dose (MTD) of flavopiridol (alvocidib) in combination with lenalidomide in patients with relapsed or refractory B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).
To define the specific toxicities and the dose limiting toxicity (DLT) of flavopiridol in combination with lenalidomide in the treatment of patients with relapsed or refractory CLL/SLL.

SECONDARY OBJECTIVES:

To assess preliminary efficacy of flavopiridol combined with lenalidomide in patients with relapsed/refractory CLL/SLL to justify future, rigorous phase II studies of the combination in CLL.
To determine the pharmacokinetics of flavopiridol and lenalidomide alone and in combination in patients with CLL/SLL.
To correlate select pre-treatment prognostic markers, including interphase cytogenetics with minimal residual disease, progression-free survival, response, and toxicity following combination therapy with flavopiridol and lenalidomide.
To determine patient cytokine expression profiles immediately pre-treatment, after flavopiridol dosing, and after combination flavopiridol and lenalidomide therapy to assess the impact of lenalidomide on flavopiridol induced cytokine release (interleukin [IL]-6).
To assess if pre-treatment ex vivo and in vivo (day 1 and day 3 of lenalidomide) immune (B-cell, natural killer [NK] cell, and T-cell) activation correlates with response and toxicity of lenalidomide therapy.
To assess the in vivo effect of lenalidomide on flavopiridol on the modulation of selected intracellular pharmacodynamic targets including signal transducer and activator of transcription 3 (acute-phase response factor) (STAT3), myeloid cell leukemia sequence 1 (BCL2-related) (Mcl-1), and other downstream IL-6 targets.

OUTLINE: This is a dose-escalation study of lenalidomide.

Patients receive alvocidib intravenously (IV) over 4.5 hours on days 1, 8, and 15 in course 1 followed by a week of rest. Beginning in course 2 and all subsequent courses, patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 and alvocidib IV over 4.5 hours on days 3, 10, and 17. Treatment repeats every 35 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 2 years.

Outcome Measures

Primary Outcome Measures

MTD of lenalidomide when combined with alvocidib, defined as the maximum dose level with fewer than 2 of 6 patients experiencing dose limiting toxicity (DLT) [Up to day 70]
Incidence of DLT in patients treated with alvocidib and lenalidomide graded according to NCI CTCAE version 4.0 [Up to day 70]
Toxicities classified as DLT during course 1 will not be considered DLT for the combination of lenalidomide and flavopiridol, but will result in patient removal from the study.

Secondary Outcome Measures

Pharmacokinetic parameters of alvocidib and lenalidomide alone and in combination in plasma samples [Baseline, day 1 of course 1, and on days 2-3 of course 2]
Samples will be analyzed in batches to assess plasma drug concentrations, the plasma drug concentration-time profile (AUC), volume of distribution (Vss), clearance (CL), and half-life. Standard paired statistical tests, parametric and nonparametric, will be used to compare baseline with treatment values. With data collected serially over time, repeated measures analysis of variance will be used to analyze data.
Plasma IL-6 and selected cytokine levels [Up to 5 years]
Standard paired statistical tests, parametric and nonparametric, will be used to compare baseline with treatment values. With data collected serially over time, repeated measures analysis of variance will be used to analyze data.
B-cell activation as assessed by surface antigen (CD40, CD80, CD86, HLA-DR, and CD95) expression [Up to 5 years]
Standard paired statistical tests, parametric and nonparametric, will be used to compare baseline with treatment values. With data collected serially over time, repeated measures analysis of variance will be used to analyze data.
