About the PERSIST Phase 3 Development Program of Pacritinib
Based on pacritinib's efficacy and tolerability profile demonstrated to date, CTI is pursuing a broad approach to advancing this therapy for patients with myelofibrosis by conducting two Phase 3 clinical trials: one in a broad set of patients without limitations on blood platelet counts, the PERSIST-1 trial, and the other in patients with low platelet counts, the PERSIST-2 trial.
In July 2014, CTI completed enrollment in the PERSIST-1 trial that was designed to enroll approximately 320 patients and is a randomized, open-label, multicenter trial comparing the efficacy and safety of pacritinib with that of best available therapy, other than JAK inhibitors, in patients with primary myelofibrosis, post-polycythemia vera myelofibrosis or post-essential thrombocythemia myelofibrosis, without exclusion for low platelet counts. The primary endpoint is the percentage of patients achieving a greater than or equal to 35 percent reduction in spleen volume measured by MRI or CT from baseline to 24 weeks of treatment.
In March 2014, CTI announced the initiation of the PERSIST-2 trial, which will evaluate pacritinib compared to best available therapy, including approved JAK2 inhibitors that are dosed according to product label, in patients with myelofibrosis whose platelet counts are less than or equal to 100,000/uL. The trial is designed to enroll up to 300 patients in North America, Europe, Australia and New Zealand. In October 2013, CTI reac
