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.
This phase I trial studies the side effects and best dose of giving bortezomib and romidepsin together in treating patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), indolent B-cell lymphoma, peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma (CTCL). Bortezomib and romidepsin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
