"With the initiation of the PERSIST-2 trial, we believe that the registration program for pacritinib is on track for a potential NDA submission in the latter part of 2015," said James A. Bianco, MD, President and CEO of CTI. "We have seen meaningful clinical benefits and good tolerability with pacritinib in myelofibrosis patients in Phase 2 trials without apparent drug-related thrombocytopenia or anemia. As such, we have had strong interest in site participation for this trial and will work diligently to activate these sites over the next several months."Pacritinib Development Program in Myelofibrosis Based on pacritinib's efficacy and tolerability profile demonstrated to date, CTI is pursuing a broad approach to advancing this therapy for myelofibrosis patients by conducting two Phase 3 clinical trials: one in a broad set of patients without limitations on blood platelet counts, the ongoing PERSIST-1 trial, and the other in patients with low platelet counts, the PERSIST-2 trial, as described above. In January 2013, CTI initiated PERSIST-1, which is a 270 patient randomized, open-label, multicenter Phase 3 trial comparing the efficacy and safety of pacritinib with that of best available therapy in patients with myelofibrosis. Best available therapy includes any physician-selected treatment other than JAK inhibitors and there is no exclusion by patient platelet count. The trial is currently enrolling patients at clinical sites in Europe, Australia, Russia and the United States. More details on the PERSIST-1 study can be found at www.clinicaltrials.gov. About Pacritinib Pacritinib is an oral tyrosine kinase inhibitor with dual activity against JAK2 and FLT3. The JAK family of enzymes is a central component in signal transduction pathways, which are critical to normal blood cell growth and development, as well as inflammatory cytokine expression and immune responses. Mutations in these kinases have been shown to be directly related to the development of a variety of blood-related cancers, including myeloproliferative neoplasms, leukemia and lymphoma. Pacritinib may offer an advantage over other JAK inhibitors through effective treatment of symptoms while having less treatment-emergent thrombocytopenia and anemia than has been seen in currently approved and in-development JAK inhibitors.
