Purpose The primary objective of this study was to confirm the efficacy of romidepsin in patients with treatment refractory cutaneous T-cell lymphoma (CTCL). Patients and Methods This international, pivotal, single-arm, open-label, phase II study was conducted in patients with stage IB to IVA CTCL who had received one or more prior systemic therapies. Patients received romidepsin as an intravenous infusion at a dose of 14 mg/m(2) on days 1, 8, and 15 every 28 days. Response was determined by a composite assessment of total tumor burden including cutaneous disease, lymph node involvement, and blood (Sezary cells). Results Ninety-six patients were enrolled and received one or more doses of romidepsin. Most patients (71%) had advanced stage disease (>= IIB). The response rate was 34% (primary end point), including six patients with complete response (CR). Twenty-six of 68 patients (38%) with advanced disease achieved a response, including five CRs. The median time to response was 2 months, and the median duration of response was 15 months. A clinically meaningful improvement in pruritus was observed in 28 (43%) of 65 patients, including patients who did not achieve an objective response. Median duration of reduction in pruritus was 6 months. Drug-related adverse events were generally mild and consisted mainly of GI disturbances and asthenic conditions. Nonspecific, reversible ECG changes were noted in some patients. Conclusion Romidepsin has significant and sustainable single-agent activity (including improvement in pruritus) and an acceptable safety profile, making it an important therapeutic option for treatment refractory CTCL.
