Pacritinib is an oral tyrosine kinase inhibitor (TKI) 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 certain blood related cancers including myeloproliferative neoplasms, leukemia and lymphoma.About the Pacritinib Phase III Program Results from earlier Phase I and II studies of pacritinib demonstrated encouraging results, including meaningful clinical benefits coupled with good tolerability among patients with advanced myelofibrosis. Based on the efficacy and tolerability profile demonstrated to date, the pivotal program for pacritinib includes two Phase III clinical trials: PERSIST-1 is studying efficacy and safety in a broad set of patients with myelofibrosis without limitations on blood platelet counts, and PERSIST-2 will evaluate efficacy and safety in patients with low platelet counts, and is expected to begin in the fourth quarter of 2013.
