The US Food and Drug Administration has accepted for priority review the new drug application for repotrectinib for the treatment of patients with ROS1-positive, locally advanced or metastatic non-small cell lung cancer (NSCLC).
Repotrectinib is an oral tyrosine kinase inhibitor (TKI) that targets ROS1– or NTRK-positive locally advanced or metastatic solid tumors. The new drug application is supported by data from the TRIDENT-1 trial (ClinicalTrials.gov Identifier: NCT03093116), which was designed to evaluate the anti-tumor activity and safety of repotrectinib in patients with advanced solid tumors, including NSCLC.
The study included 4 NSCLC expansion cohorts: ROS1 TKI-naïve patients (cohort 1); patients previously treated with 1 ROS1 TKI and 1 platinum-based chemotherapy (cohort 2); patients previously treated with 2 ROS1 TKIs and no chemotherapy (cohort 3); and patients previously treated with 1 ROS1 TKI and no prior chemotherapy (cohort 4).

The objective response rate (the primary endpoint) was 79% in cohort 1, 42% in cohort 2, 28% in cohort 3, and 38% in cohort 4. Repotrectinib demonstrated durable responses in both TKI-naïve and TKI-pretreated patients, including those with ROS1 resistance mutations.
The most commonly reported treatment-emergent adverse events included dizziness, dysgeusia, constipation, anemia, paresthesia, dyspnea, fatigue, nausea, and increased alanine transaminase.
A Prescription Drug User Fee Act target date of November 27, 2023, has been set for the application.
