Theliatinib, a potent and highly selective EGFR inhibitor, with anti-tumor activity. Ki of 0.05 nM for wild type EGFR, and IC50s of 3 and 22 nM for EGFR and EGFR T790M/L858R mutant, respectively.

EGFR:0.05 nM (Ki), EGFR:3 nM (IC50), EGFR (L858R/T790M):22 nM (IC50)

Seven- to nine week old NOD-SCID immunodeficient or BALB/cASlac-nu/nu male or female mice. Fresh tumor specimens from newly diagnosed patients were collected during surgery and separated into three parts for the following: (1) To prepare formalin fixed paraffin embedded (FFPE) sections; (2) For snap freezing in liquid nitrogen for DNA extraction and sequencing and (3) For subcutaneous implantation into NOD-SCID mice (P0) and subsequent passages in additional NOD-SCID or nude mice once the tumor size reached 800~1500 mm^3. After several consecutive in vivo passages, the PDECX models (P3~P7) were used to evaluate the anti-tumor efficacy of theliatinib or gefitinib or AZD4547.
