The US Food and Drug Administration (FDA) has granted orphan drug designation to CG’806 for the treatment of patients with acute myeloid leukemia (AML).
CG’806 is an oral, first-in-class pan-FLT3/pan-BTK inhibitor being developed by Aptose Biosciences Inc.
In preclinical studies, CG’806 inhibited all wild-type and mutant forms of FLT3 tested, suppressed multiple oncogenic pathways operative in AML, and eliminated AML tumors (without toxicity) in murine xenograft models.
In addition, CG’806 demonstrated non-covalent inhibition of the wild-type and Cys481Ser mutant forms of the BTK enzyme, as well as other oncogenic kinases operative in B-cell malignancies.
Preclinical results with CG’806 were presented as posters at the AACR conference “Hematologic Malignancies: Translating Discoveries to Novel Therapies,” which took place last May.
“Results from non-clinical studies that we and our research collaborators have generated are promising and give reason for our eagerness to begin clinical trials in both AML and B-cell malignancies in 2018,” said William G. Rice, PhD, chairman, president, and chief executive officer at Aptose.
“We are pleased that the FDA has recognized the unique potential of CG’806 to address AML and has assigned CG’806 the status of orphan drug designation.”
About orphan designation
The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.
The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved.
