Aptose Biosciences Inc a clinical-stage company developing highly differentiated therapeutics that target the underlying mechanisms of cancer, announced that preclinical data for its pan-FLT3/BTK inhibitor CG’806 will be presented in two separate posters at the 2017 American Association for Cancer Research (AACR) Conference Hematologic Malignancies: Translating Discoveries to Novel Therapies, being held May 6-9 in Boston, MA.
Aptose is developing CG’806, a first-in-class pan-FLT3/BTK inhibitor, for acute myeloid leukemia (AML) and other hematologic malignancies. CG’806 is a highly potent inhibitor of the wild type and mutant forms of FLT3 (including internal tandem duplication, or ITD, and mutations of the receptor tyrosine kinase domain and the gatekeeper region), eliminates AML tumors in the absence of toxicity in murine xenograft models, and represents a potential best-in-class therapeutic for patients with FLT3-driven AML. In addition, CG’806 is a reversible, non-covalent, inhibitor of the wild type and mutant forms of the BTK enzymes. The spectrum of activity against specific clusters of kinase enzymes supports the development of CG’806 for AML, certain B cell malignancies and other hematologic malignancies.
Two separate presentations are planned for CG’806. Aptose scientists, with researchers from the Knight Cancer Institute at Oregon Health & Science University (OHSU), will present data related to the potency of CG’806 against various hematologic malignancy cell lines and patient bone marrow specimens. In a separate presentation, Aptose scientists, with researchers from the MD Anderson Cancer Center, will present data demonstrating CG’806’s potent activity against AML cells harboring specific wild type or mutant forms of FLT3.
