At data cutoff (June 20, 2022), 0 of 7 responders in the TKI-naïve cohort and 2 of 5 in the cohort with 1 prior TKI and no chemo had intracranial progression or death; intracranial DOR range was 1.9-14.8+ mo (TKI-naïve) and 3.0-11.1+ mo (1 TKI and no chemo), with 86% and 80% of pts with an intracranial response remaining on treatment, respectively....In TRIDENT-1, repotrectinib showed durable clinical activity in ROS1 TKI-naïve and -pretreated pts with or without BL CNS mets, including intracranial responses. Repotrectinib safety profile was similar in pts with ROS1+ NSCLC with or without CNS mets.
