Grade ≥3 treatment-related adverse events were observed in 55.73% and 42.86% of participants in the envonalkib and crizotinib groups, respectively. Envonalkib significantly improved PFS and delayed brain metastasis progression in advanced ALK-positive NSCLC.
Conclusions Compared with Cri, Env significantly prolonged PFS in advanced ALK-positive NSCLC pts who had not received a prior ALK inhibitor, and showed greater advantages in controlling BMs. The safety profiles following Env treatment were manageable.
