Romidepsin for Cutaneous T-cell Lymphoma

Abstract

Cutaneous T-cell lymphomas (CTCL) are relatively rare lymphomas with an annual incidence of approximately 0.2 to 0.8/100,000 and comprise a variety of clinical entities; mycosis fungoides or its leukemic variant Sezary syndrome account for the majority of cases. Advanced-stage disease is typically treated with bexarotene (a retinoid), interferon, or conventional chemotherapeutic agents, but relapses are inevitable. Histone deacetylase inhibitors, which modify the epigenome, are an attractive addition to the armamentarium. On the basis of 2 large phase II studies, the U.S. Food and Drug Administration approved intravenous romidepsin for patients with relapsed and/or refractory CTCL. Romidepsin provides a subset of patients with an opportunity for prolonged clinical responses with a tolerable side effect profile.
