摘要

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 with wild-type EGFR. In a xenograft model, oral administration of AC0010 at a daily dose of 500 mg/kg resulted in complete remission of tumors with EGFR-active and T790M mutations for over 143 days with no weight loss. Three major metabolites of AC0010 were tested and showed no wild-type EGFR inhibition or off-target effects, such as inhibition of IGF-1R. AC0010 is safe in non-small cell lung cancer (NSCLC) patients at a dose range between 50 and 550 mg once per day, and no hyperglycemia or other severe adverse effects were detected, such as grade 3 QT prolongation. The objective responses were observed in NSCLC patients with EGFR T790M mutation.
