At last contact, 268 patients (51.1%) had discontinued therapy, and the median drug exposure was 17.5\u00a0months. Fifty patients (18.7%) died while taking ruxolitinib. The reasons for discontinuation in the remaining 218 patients were the lack (22.9%) or loss (11.9%) of a spleen response, ruxolitinib\u2010related adverse events (27.5%), progression to blast phase (23.4%), ruxolitinib\u2010unrelated adverse events (9.2%), and allogeneic transplantation during response (5.1%). The median survival after ruxolitinib was 13.2\u00a0months and was significantly better in the 167 patients who discontinued ruxolitinib in chronic phase (27.5 vs 3.9\u00a0months for those who discontinued in blast phase; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001). No survival differences were observed among patients who discontinued ruxolitinib in chronic phase because of lack of response, loss of response, or ruxolitinib\u2010related adverse events.
