Abstract Text

Ibrutinib, an inhibitor of Bruton tyrosine kinase (BTK), has shown promising pharmacologic effects in acute myeloid leukemia (AML). In this study, we report that abivertinib or AC0010, a novel BTK inhibitor, inhibits cell proliferation, reduces colony-forming capacity, and induces apoptosis and cell cycle arrest in AML cells, especially those harboring FLT3-ITD mutations. Abivertinib was also found to be more sensitive than ibrutinib in treating AML. We demonstrate that in addition to targeting the phosphorylation of BTK, abivertinib also targeted the crucial PI3K survival pathway. Furthermore, abivertinib suppressed the expression of p-FLT3 and the downstream target p-STAT5 in AML cells harboring FLT3-ITD mutations. Moreover, in vitro and in vivo data revealed synergistic activity between abivertinib and homoharringtonine (HHT), a natural plant alkaloid commonly used in China, in treating AML cells with or without FLT3-ITD mutations. Collectively, these preclinical data suggest that abivertinib may be a promising novel agent for AML, with potential for combination treatment with HHT. Clinical studies on abivertinib-involved therapy are planned.

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.

Abivertinib		Avitinib\|AC0010\|AC0010MA	BTK inhibitor 37 EGFR Inhibitor 3rd gen 26	Abivertinib (AC0010) is a BTK inhibitor and a third-generation EGFR inhibitor that blocks the activity of mutant forms of EGFR while sparing wild-type EGFR, which potentially results in increased apoptosis and cell cycle arrest, and decreased viability and colony formation, and inhibits tumor growth (PMID: 27573423, PMID: 31310800).

FLT3 exon 14 ins	acute myeloid leukemia	sensitive	Abivertinib + Omacetaxine mepesuccinate	Preclinical - Patient cell culture	Actionable	In a preclinical study, treatment with the combination of Abivertinib (AC0010) and Synribo (omacetaxine mepesuccinate) resulted in increased apoptosis and reduced viability of acute myeloid leukemia (AML) cell lines harboring FLT3-ITD mutations and decreased viability of patient-derived AML cells harboring FLT3-ITD mutations in culture, and reduced tumor burden and increased survival in cell line xenograft models compared to either agent alone (PMID: 31310800).	31310800
FLT3 exon 14 ins	acute myeloid leukemia	predicted - sensitive	Ibrutinib	Preclinical - Cell culture	Actionable	In a preclinical study, Imbruvica (ibrutinib) treatment reduced viability of acute myeloid leukemia cells harboring FLT3-ITD mutations, however, with decreased response compared to cells treated with Abivertinib (AC0010) in culture (PMID: 31310800).	31310800
