This is a randomized, controlled, open-label, multicenter, phase 3 clinical study to valuate the efficacy and safety of ASKC202 combined with Limertinib in locally advanced or metastatic NSCLC with MET amplification/overexpression after failure of EGFR inhibitor therapy. Participants will continue to receive treatment until disease progression, intolerable toxicity, withdrawal of informed consent, death, or any other reasons for treatment discontinuation, whichever occurs first.
