05:37 EDTCTICCTI announce UK National Cancer Research Institute Phase 2 trial for Pacritinib
Cell Therapeutics announced the initiation of an international cooperative group Phase 2 clinical trial of pacritinib in adult patients with relapsed acute myeloid leukemia, or AML, with mutations of the FLT3 gene. Mutation of the FLT3 gene is found in approximately one-third of AML patients and is an independent risk factor for poor prognosis. Pacritinib is an oral JAK2/FLT3 inhibitor that has demonstrated encouraging activity in preclinical models of AML with mutated FLT3 gene, including additional FLT3 mutations that confer resistance to other targeted FLT3 agents. The trial is being conducted by the AML Working Group of the National Cancer Research Institute Haematological Oncology Study Group in AML and high risk Myelodysplastic Syndrome under the sponsorship of Cardiff University and supported by Cancer Research UK. This Phase 2 trial is part of a larger ongoing study in AML, referred to as the AML17 trial, which includes multiple arms evaluating first line regimens for AML. Patients with the FLT3 mutation, who are enrolled in this study and relapse following standard therapy, will be offered therapy with pacritinib. Approximately 80 patients at sites in England and Wales will be enrolled and, if an encouraging response rate is observed, a pacritinib arm may be adopted in the first line therapy study.

14:25 EDTCTICCTI BioPharma announces analysis of kinase inhibition by pacritinib
CTI BioPharma announced that an analysis of kinase inhibition by pacritinib, a next generation oral multikinase inhibitor in Phase 3 clinical development, demonstrated a unique kinome profile among agents in development for myelofibrosis and suggests potential therapeutic benefit across a spectrum of blood-related cancers. Researchers presented the findings from this analysis at the 56th American Society of Hematology Annual Meeting and Exposition held December 6-9 in San Francisco, CA."The kinome profile of pacritinib shown in this analysis highlights how pacritinib is different from other JAK inhibitors that are currently on the market and in development for myelofibrosis," said Srdan Verstovsek, M.D., Ph.D., Director, Clinical Research Center for MPNs at The University of Texas MD Anderson Cancer Center and principal investigator for the Phase 3 PERSIST-2 trial of pacritinib. "One of the findings observed in clinical trials to date is the lack of myelosuppression seen with other treatments. Pacritinib's potent inhibition of FLT3, c-fms, IRAK1 and c-kit, all critical targets in hematologic malignancies, highlights its potential therapeutic utility in other indications, such as AML, MDS, CMML and CLL." The in vitro profiling of pacritinib across a panel of kinases showed the inhibition of all members of the JAK/FLT pathways, with the exception of JAK1. The JAK/FLT pathways are frequently dysregulated in many types of cancers. Additionally, pacritinib was found to inhibit the kinases c-fms and IRAK1. Disruption in the c-fms and IRAK1 pathways have been indicated to be involved in acute myeloid leukemia, myelodysplastic syndrome, chronic myelomonocytic leukemia and chronic lymphocytic leukemia. CTI believes the clinical efficacy and reduced myelosuppression seen in Phase 2 trials of pacritinib in patients with myelofibrosis is also likely attributable to this unique kinase inhibition profile. "These data not only demonstrate the unique attributes of pacritinib compared to other marketed agents or agents in development for the treatment of myelofibrosis, many of which have activity against JAK1, but also show the potential for broader use in other blood-related cancers," said Jack Singer, M.D., Executive Vice President, Global Medical and Translational Medicine at CTI and lead author of the analysis. "We are excited to pursue additional indications, such as AML, MDS, CMML and CLL, all of which are currently being evaluated in Phase 2 clinical trials, so we can potentially offer these patients an effective and less toxic treatment option."
