Bortezomib and Romidepsin in Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

OBJECTIVES:

Primary

• Determine the maximum tolerated dose (MTD) for the combination of bortezomib and romidepsin administered weekly x 3 every (q) 4wk in patients with CLL/SLL, indolent B-cell lymphoma, PTCL or cutaneous T-cell lymphoma (CTCL).

Secondary

• Determine safety and tolerance and describe the toxicities of the combination.
• Demonstrate adequate methods for the assessment of pharmacodynamic responses of CLL cells to the combination with respect to effects on NF-kappa B (nuclear RelA and processing of p52 as a marker of p100 processing), expression of the NF-kappa B-dependent proteins XIAP and Bcl-xL, and Bim, and document pharmacodynamic responses observed in the course of this study * Document the pharmacodynamic responses associated with this regimen in these patients.
• Document the anticancer activity of this regimen in these patients.

OUTLINE: Patients receive bortezomib IV over 3-5 seconds and romidepsin IV over 4 hours on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Blood samples from patients with chronic lymphocytic leukemia are collected at baseline and after day 1 of course 1 of study treatment for pharmacodynamic and correlative laboratory studies.
