AstraZeneca and BIND Therapeutics (formerly BIND Biosciences) are collaborating to develop AZD-1152HQPA (AZD2811) for the treatment of cancer. AZD2811, a novel, selective inhibitor of Aurora B kinase that has been shown to be active in both solid and hematological tumors in preclinical models, is the second Accurin candidate to enter clinical development. AZD1152-HQPA is a highly selective Aurora B inhibitor with IC50 of 0.37 nM in a cell-free assay. AZD1152-HQPA inhibited the proliferation of AML lines (HL-60, NB4, MOLM13), ALL line (PALL-2), biphenotypic leukemia (MV4-11), acute eosinophilic leukemia (EOL-1), and the blast crisis of chronic myeloid leukemia K562 cells with an IC50 ranging from 3 nM to 40 nM. The phase 1 trial is enrolling patients with advanced solid tumors, including patients with small cell lung cancer, and is being conducted by AstraZeneca under the companies’ 2013 collaboration agreement with BIND managing all chemistry, manufacturing and control activities.
