CTI BioPharma Announces Data Presentations at the 56th American Society of Hematology Annual Meeting
SEATTLE, Dec. 1, 2014 /PRNewswire/ -- CTI BioPharma Corp. (CTI) (NASDAQ and MTA: CTIC) today announced the upcoming presentations of data highlighting pacritinib, an oral multikinase inhibitor with dual activity against JAK2 and FLT3, and tosedostat, an oral selective inhibitor of aminopeptidases, at the 56th American Society of Hematology (ASH) Annual Meeting and Exposition, being held December 6-9 in San Francisco, CA.
The presentations will include data on the activity of pacritinib in stroma adherent acute myeloid leukemia (AML) cells, a profile of kinase inhibition across several cell signaling pathways with pacritinib treatment and analysis of a Phase 2 trial of treatment with tosedostat in combination with cytarabine or decitabine in patients with AML or myelodysplastic syndrome (MDS). A summary of the presentations is below, and full abstracts can be accessed on the ASH website at www.hematology.org.

A Comparative Analysis of Dual JAK2/FLT3 Inhibitors Revealed the Effectiveness of Pacritinib in Combating Genetic Resistance
First Author: Meenu Kesarwani, Ph.D., Cincinnati Children's Hospital Medical Center, Cincinnati, OH
About Pacritinib
Pacritinib is a next generation oral multikinase 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.
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. The PERSIST-1 trial has completed enrollment with top-line results expected in the first quarter of 2015. The PERSIST-2 trial is actively enrolling patients.
In November 2013, CTI and Baxter International (Baxter) entered into a worldwide license agreement to develop and commercialize pacritinib in which CTI and Baxter will jointly commercialize pacritinib in the U.S. and Baxter has exclusive commercialization rights for all indications outside the U.S.
About Tosedostat
Tosedostat is an oral aminopeptidase inhibitor that has demonstrated anti-tumor responses in blood-related cancers and solid tumors in Phase 1–2 clinical trials. Presently, an ongoing Phase 2/3 trial is being conducted by the National Cancer Research Institute Haematological Oncology Study Group under the sponsorship of Cardiff University. In this Phase 2/3 trial, referred to as the AML Less Intensive (LI-1) trial, patients will be randomized to standard treatment, low dose cytarabine, versus one of five novel investigational treatments, one of which is tosedostat, each in combination with low dose cytarabine. Overall survival will serve as the primary endpoint of this trial.
