Bristol Myers Squibb announced that the European Medicines Agency (EMA) has validated its marketing authorization application for the next-generation tyrosine kinase inhibitor (TKI) repotrectinib as a treatment for ROS1 TKI-naïve and -pretreated adult patients with ROS1-positive locally advanced or metastatic non-small cell lung cancer (NSCLC) and TKI-naïve and -pretreated adult and pediatric patients 12 years and older with NTRK-positive locally advanced or metastatic solid tumors. The application was based on results from the registrational Phase 1/2 TRIDENT-1 trial (adult patients with ROS1-positiveNSCLCor NTRK-positivesolid tumors) and CARE study (pediatric patients with NTRK-positivesolid tumors). Validation of the application confirms the submission is complete and begins the EMA?s centralized review procedure.

In the TRIDENT-1 and CARE trials, repotrectinib demonstrated clinically meaningful response rates in patients across ROS1-positive NSCLC and NTRK-positive solid tumor cohorts. Durability of response was robust and intracranial responses were observed in both settings, as well as in patients whose tumors harbor common resistance mutations. The safety profile of repotrectinib was well characterized and generally manageable with routine standard-of-care treatments.

The study remains ongoing to assess long-term outcomes and additional endpoints across patient populations with ROS1-positive locally advanced or metastatic NSCLC and NTRK-positive locally advanced or metastatic solid tumors.
