Group 1: Drug Approval and Clinical Trial Results - The approval of limertinib is based on positive outcomes from a Phase 3 clinical trial involving 337 treatment-naïve patients, which demonstrated significant improvements in progression-free survival (PFS) compared to gefitinib [2][3]. - Limertinib achieved a median PFS of 20.7 months versus 9.7 months for gefitinib, indicating a 56% risk reduction in disease progression or death [3]. - In patients with central nervous system (CNS) lesions, limertinib also showed a median CNS PFS of 20.7 months compared to 7.1 months, representing a 72% risk reduction for CNS progression or death [3]. Group 2: Safety Profile and Efficacy - The safety profile of limertinib aligns with known EGFR-targeted therapies, with adverse events primarily mild to moderate and no new safety signals identified during the trial [4]. - The drug has shown exceptional efficacy as a first-line therapy, particularly in patients with brain metastases, addressing a critical clinical need in this population [5].
