Abstract Text

FMS-like Tyrosine Kinase 3 (FLT3) mutation is associated with poor survival in AML. The specific Anexelekto/MER Tyrosine Kinase (AXL) inhibitor ONO-7475 kills FLT3-mutant acute myeloid leukemia cells with targets including Extracellular-signal Regulated Kinase (ERK) and Myeloid Cell Leukemia 1 (MCL1). ERK and MCL1 are known resistance factors for Venetoclax (ABT-199), a popular drug for AML therapy, prompting the investigation of the efficacy of ONO-7475 in combination with ABT-199 in vitro and in vivo. ONO-7475 synergizes with ABT-199 to potently kill FLT3-mutant acute myeloid leukemia cell lines and primary cells. ONO-7475 is effective against ABT-199-resistant cells including cells that overexpress MCL1. Proteomic analyses revealed that ABT-199-resistant cells expressed elevated levels of pro-growth and anti-apoptotic proteins compared to parental cells, and that ONO-7475 reduced the expression of these proteins in both the parental and ABT-199-resistant cells. ONO-7475 treatment significantly extended survival as a single agent in vivo using acute myeloid leukemia cell lines and PDX models. Compared to ONO-7474 monotherapy, the combination of ONO- 7475/ABT-199 was even more potent in reducing leukemic burden and prolonging survival of mice in both model systems. These results suggest the ONO-7475/ABT-199 combination may be effective for acute myeloid leukemia therapy.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

FLT3 exon 14 ins	acute myeloid leukemia	sensitive	ONO-7475	Preclinical - Pdx & cell culture	Actionable	In a preclinical study, ONO-7475 treatment inhibited Erk phosphorylation and cell viability in acute myeloid leukemia cell lines harboring a FLT3-ITD mutation in culture, and reduced leukemia burden and prolonged survival in patient-derived xenograft (PDX) and cell line xenograft models (PMID: 34732043).	34732043
FLT3 exon 14 ins	acute myeloid leukemia	sensitive	ONO-7475 + Venetoclax	Preclinical - Pdx & cell culture	Actionable	In a preclinical study, the combination of ONO-7475 and Venclexta (venetoclax) synergistically inhibited cell viability and induced apoptosis in acute myeloid leukemia cell lines harboring a FLT3-ITD mutation in culture, and reduced leukemia burden and prolonged overall survival in patient-derived xenograft (PDX) and cell line xenograft models with increased efficacy over either agent alone (PMID: 34732043).	34732043
