Overall survival (OS) of patients with TRK fusion–positive cancer receiving larotrectinib versus standard of care (SoC): A matching-adjusted indirect comparison (MAIC) using real-world data (RWD).
Excerpt:85 larotrectinib patients and 28 SoC patients were included. After matching, log-rank testing suggested no difference between the 2 groups (P=0.26), and larotrectinib was associated with a 78% lower risk of death (adjusted HR: 0.22 [95% confidence interval: 0.09, 0.54]; P=0.001), compared to SoC....This analysis suggests longer overall survival with larotrectinib, compared to SoC, in adult patients with TRK fusion cancer.
