In this preclinical study, we evaluated the anti-leukemic efficacy of EBD-300, a novelmammalian-derived asparaginase lacking glutaminase activity, in combination with Venetoclax(VEN).<h4>Results</h4>EBD-300 monotherapy exhibited significant activity in AML cell lines harboringchromosome 7/7q deletions, which are likely dependent on extracellular asparagine due to thepresence of only a single copy of the asparagine synthetase (ASNS) gene - the enzymeresponsible for endogenous asparagine synthesis. Here, GLS is linked to acute myeloid leukemia.
