Tapan Kadia, MD, The University of Texas MD Anderson Cancer Center, Houston, TX, highlights data coming from a Phase IB study of itacitinib combined with alemtuzumab in patients with T-cell prolymphocytic leukemia (T-PLL). To date, alemtuzumab has been the most effective therapy available for patients with T-PLL, although responses are not durable. In this study, patients initially treated with single agent itacitinib reported improvements in symptoms including rash and appetite. Following the addition of alemtuzumab, a high overall response rate (ORR) of 88% was observed in newly diagnosed patients, and an ORR of 57% in previously treated patients. A future study of the combination therapy, without the initial 2-week single agent itacitinib, is planned.
