About Pacritinib

Pacritinib is an oral tyrosine kinase inhibitor (TKI) with dual activity against JAK2 and FLT3.  The JAK family of enzymes are 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.

CTI is pursuing a broad approach to advancing pacritinib 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 will be in patients with low platelet counts, the PERSIST-2 trial, which is expected to begin in the fourth quarter of 2013.  In October 2013, we reached agreement with the U.S. Food and Drug Administration on a Special Protocol Assessment, or SPA, for the PERSIST-2 pivotal trial.  A SPA is a written agreement between CTI and the FDA regarding the design, endpoints and planned statistical analysis approach of the trial to be used in support of a potential New Drug Application, or NDA, submission.  

About Tosedostat

Tosedostat is an oral, aminopeptidase inhibitor that has demonstrated significant anti-tumor responses in blood-related cancers and solid tumors in Phase 1-2 clinical trials.  CTI has exclusive marketing and co-development rights to Chroma Therapeutics Ltd.'s drug candidate tosedostat in North, Central and South America.
