“CG-806 has the potential to serve as a transformational agent for AML, chronic lymphocytic leukemia (CLL) and other hematologic malignancies,” said William G. Rice, Ph.D., chairman, president and chief executive officer of Aptose. “Recent pre-clinical studies, just highlighted at the 2018 AACR Annual Meeting, demonstrated CG-806’s superior potential to other FLT3 inhibitors on AML patient samples and superior potential to ibrutinib on CLL patient samples.”

Aptose Biosciences and CrystalGenomics announced that Aptose exercised its option under the 2016 Option Agreement to exclusively license CG-806, a first-in-class, non-covalent pan-inhibitor of the Bruton’s tyrosine kinase (BTK) and FMS-like tyrosine kinase 3 (FLT3) from CrystalGenomics.
Aptose has been conducting Investigational New Drug (IND) enabling studies with CG-806, as well as numerous preclinical studies. When tested against fresh bone marrow samples from patients with AML, CG-806 demonstrated superior potency and range of activity relative to all other FLT3 inhibitors evaluated. Likewise, CG-806 demonstrated superiority over ibrutinib when tested against samples from CLL patients.
"Aptose has made the clinical development of CG-806 a priority, and we are pleased to be working with them,” said Joong Myung Cho, Ph.D., chairman and chief executive officer of CrystalGenomics. “Aptose and its clinical advisors clearly recognize the potential of CG-806 as an exciting therapeutic option for patients with AML, CLL and other malignancies.”
CG-806 is being developed as a highly potent, oral small molecule for acute myeloid leukemia (AML), B-Cell malignancies and other hematologic malignancies.
With the early exercise of the option, Aptose owns global rights to develop and commercialize CG-806 for all indications outside of Korea and China – the Licensed Territory. The exercise triggers a payment of US $2.0 million to CrystalGenomics. CrystalGenomics is eligible for regulatory and sales milestone payments, as well as royalties on product sales in the Licensed Territory.
