CLINICAL NEWS Written in Featured research from recent issues of Blood PAPER SPOTLIGHT Combining Romidepsin and Pralatrexate in Relapsed/ Refractory T-Cell Lymphoma: Are Two Drugs Better Than One? In a phase I trial of patients with relapsed/refractory peripheral T-cell lymphoma (PTCL), combin- ing romidepsin and pralatrexate – two agents approved by the U.S. Food and Drug Administration for this indication – led to an overall response rate (ORR) of 71 percent, doubling the ORR that had previ- ously been seen with either agent alone. “PTCL is a group of rare, het- erogeneous malignancies with an aggressive course, character- ized by relative insensitivity to conventional chemotherapy and an inferior prognosis, compared [with] their B-cell counterparts,” Jennifer E. Amengual, MD, from the Center for Lymphoid Malignancies and Hebert Irving Comprehensive Cancer Center at Columbia University Medical Cen- ter in New York, and colleagues explained in the report published in Blood. Adding agents or trans- plantation to CHOP (cyclophos- phamide, doxorubicin, vincristine, prednisone) has led to “modest and marginal” improvements in survival, but by combining two new agents, the authors hoped to exploit the synergy observed in preclinical models of PTCL, without increasing toxicity. 18 ASH Clinical News This single-center, dose-escalation trial included 29 patients (median age = 54 years; range = 23-73 years) with previously treated PTCL. Patients were required to have an Eastern Cooperative On- cology Group performance status score of ≤2 and adequate organ and marrow function. People were ineligible for inclusion if they had central nervous system disease or lymphomatous menin- gitis or took concomitant CYP3A4 inhibitors. Seven patients (24%) had B-cell lymphomas and 18 (62%) had T- cell lymphomas, while four (14%) had blastic plasmacytoid dendritic neoplasm or H
