Aptose Biosciences and CrystalGenomics Announce Issuance of Japanese Patent for CG-806
SAN DIEGO, TORONTO, and SEOUL, July 10, 2018 (GLOBE NEWSWIRE) -- Aptose Biosciences Inc. (“Aptose” or the “Company”) (NASDAQ:APTO) (TSX:APS), today announced that the Japan Patent Office has issued Japanese Patent No. 6325573 for CG-806. The granted patent claims various compounds, including the CG-806 compound, pharmaceutical compositions comprising the CG-806 compound, and uses for the treatment of various diseases, such as cancer. The patent is expected to provide protection until the end of 2033.
“This newly issued patent extends the CG-806 patent protection into an important market and is a welcome addition to the US patent that was issued last year,” stated Dr. William G. Rice, Chairman, President and Chief Executive Officer of Aptose. “As noted previously, we plan to continue expansion of the patent portfolio through additional findings and applications.”
About CG-806
CG-806 is an oral, first-in-class pan-FLT3/pan-BTK multi-kinase inhibitor. This small molecule demonstrates potent inhibition of wild type and mutant forms of FLT3 (including internal tandem duplication, or ITD, and mutations of the receptor tyrosine kinase domain and gatekeeper region), eliminates acute myeloid leukemia (AML) tumors in the absence of toxicity in murine xenograft models, and represents a potential best-in-class therapeutic for patients with AML. Likewise, CG-806 demonstrates potent, non-covalent inhibition of the wild type and Cys481Ser mutant forms of the BTK enzyme, as well as other oncogenic kinase pathways operative in B cell malignancies, suggesting CG-806 may be developed for various B cell malignancy patients (including CLL, MCL, DLBCL and others) that are resistant/refractory/intolerant to covalent BTK inhibitors.
