About Silevertinib

Silevertinib is an investigational oral, covalent, brain-penetrant fourth-generation tyrosine kinase inhibitor (TKI) that selectively targets classical and more than 50 non-classical EGFR mutations in NSCLC. It is also designed to potently inhibit key EGFR alterations seen in GBM, including EGFRvIII, while avoiding the paradoxical EGFR activation reported with reversible TKIs. To date, over 200 patients with EGFRm NSCLC or EGFR-altered GBM have been treated with silevertinib.

In addition to the ongoing Phase 2 trial of silevertinib in patients with non-classical EGFRm NSCLC, the Company is also conducting a randomized Phase 2 trial of silevertinib in patients with newly diagnosed EGFRvIII-positive GBM (NCT07326566).
