Laboratory correlates for a phase II trial of romidepsin in cutaneous and peripheral T-cell lymphoma.

ABSTRACT: Romidepsin has shown promise in the treatment of T-cell lymphomas, and so we evaluated molecular endpoints gathered from 61 patients enrolled on a phase II trial of romidepsin in cutaneous and peripheral T-cell lymphoma at the National Institutes of Health. The endpoints included histone H3 acetylation and ABCB1 gene expression in peripheral blood mononuclear cells (PBMCs); ABCB1 gene expression in tumour biopsy samples; and blood fetal haemoglobin levels (HbF), all of which were increased following romidepsin treatment. The fold increase in histone acetylation in PBMCs at 24 h was weakly to moderately well correlated with the pharmacokinetic parameters C(max) and area under the curve (AUC)(last) (rho = 0.37, P = 0.03 and rho = 0.36, P = 0.03 respectively) and inversely associated with cle
