In Vitro

In vitro activity: Avitinib (also known as Abivertinib, AC0010, AC0010MA) is an oral, potent, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor selective for T790M resistance mutations. AC0010 is a pyrrolopyrimidine-based irreversible EGFR inhibitor, structurally distinct from previously reported pyrimidine-based irreversible EGFR inhibitors, such as osimertinib and rociletinib. AC0010 selectively inhibits EGFR active and T790M mutations with up to 298-fold increase in potency compared to wild-type EGFR. AC0010 selectively inhibited mutant EGFR phosphorylation with IC50 values of 7.3 nM and 2.8 nM in NCI-H1975 and NIH/3T3_TC32T8 cells, about 115- and 298-fold more sensitive than that of the inhibition of wild type EGFR in A431. Immunoblotting analysis confirmed that AC0010 potently inhibited EGFR-Tyr1068 phosphorylation in NCI-H1975 cells, and the selectivity ratio is at 65-fold for NCI-H1975 cells versus A431 cells. In addition to inhibition of EGFR-Tyr1068 phosphorylation, AC0010 inhibited phosphorylation of the downstream targets Akt and ERK1/2, two important kinases involved in cancer cell proliferation and survival, in NCI-H1975 and HCC827 cells. The selectivity of AC0010 was also assessed by testing its activity against a panel of 349 kinases. At a concentration of 1 μM, AC0010 exhibited greater than 80% inhibition in 33 out of 349 unique kinase assays (9.5%). Kinase targets with greater than 80% inhibition include JAK3, BTK and 5 TEC family members. However, at the cellular level, the kinase inhibitory potency is much less than with the enzymatic assay. Much weaker inhibition was seen in BTK and JAK3 cellular assays with IC50 values of 59 nM and 360 nM. When tested against a selected panel of 55 key molecular targets including receptors, ion channels and transporters, AC0010 (1 μM) inhibits 5 out of 55 targets over 50% inhibition of radioligand binding, including Adenosine A3, L-type calcium (Cav1.2) channel, dopamine transporter, 5-HT2A and 5-HT2B. However, in cell-based functional assays, no inhibition was detected for above 5 targets, implying that the risk of off-target binding of AC0010 is minimal at pharmacologically relevant concentrations


Kinase Assay: Kinase activity assay was performed by service provider, Reaction Biology Corp (Malvern, PA, USA). For the single dose screening assay, AC0010 concentration at either 1 μM or 10 μM was used. For IC50 value determinations, a 10-concentration gradient from 5.1x10-11-1.0x10-6 mol/L was set for the tested compounds. Staurosporine served as a control compound to monitor assay quality for IC50 value determinations and one-dose kinase activity assay.


Cell Assay: Cell proliferation is assayed by a cell viability reagent, WST-1. Cells are seeded at optimal density onto 96-well plates and incubated for 24 hours, followed by avitinib treatment for 72 hours. Cell viability is then assayed by incubating cells with WST-1 reagent for 2-3 hrs.

In Vivo Oral administration of avitinib at daily dose of 500 mg/kg results in complete remission of tumors with EGFR active and T790M mutations for over 143 days with no weight loss. Three major metabolites of avitinib are tested and show no wild-type EGFR inhibition and off-target effects such as inhibition of IGF-1R. Avitinib is safe in non-small cell lung cancer (NSCLC) patients at the dose range between 50 mg and 550 mg once per day and no hyperglycemia and other severe adverse effects are detected such as grade 3 QT prolongation[
