      Background

      Neurotrophic receptor tyrosine kinase (NTRK) gene fusions lead to the expression of chimeric TRK proteins with constitutively activated kinase function, conferring oncogenic potential across several tumour types. Entrectinib is a CNS-active, potent inhibitor of TRKA/B/C and ROS1. We present integrated efficacy and safety data for entrectinib in NTRK fusion-positive (NTRK-FP) solid tumours focusing on pts with NSCLC.

      Pts with locally advanced/metastatic NTRK-FP tumours (with or without baseline CNS disease) confirmed by nucleic acid-based methods, enrolled in global (>150 sites, 15 countries) phase 1/2 entrectinib trials (ALKA-372-001 [EudraCT 2012-000148-88], STARTRK-1 [NCT02097810], STARTRK-2 [NCT02568267]) were included. Disease burden was assessed per BICR using RECIST v1.1, after cycle 1 (4 wks) then every 8 wks. Primary endpoints: ORR, DOR by BICR. Secondary endpoints: PFS, OS, and safety.

      Outcomes in the total efficacy-evaluable population (n = 54; 10 tumour types, >19 histopathologies) are shown in the table; responses were seen in all tumour types, median PFS 11.2 mo. In the cohort of pts with NTRK-FP NSCLC (n = 10), BICR ORR was 70% (7/10). In NSCLC pts with CNS disease per investigator at baseline (n = 6), 4 had an intracranial response (2 complete, 2 partial); 1 had stable disease and 1 was not evaluable. In the safety population (68 pts with NTRK-FP solid tumors who received at least 1 dose of entrectinib), most treatment-related adverse events (TRAEs) were grade 1–2; grade 3: 32.4%, grade 4: 2.9%; no grade 5 TRAEs. TRAEs resulted in discontinuation in 4.4% and dose reduction in 39.7% of pts.

      fd69c5cf902969e6fb71d043085ddee6 Conclusions

      In this integrated analysis of global multicentre clinical trials, entrectinib was well tolerated and induced clinically meaningful, durable systemic and intracranial responses in pts with NTRK-FP solid tumours, including those with NSCLC. (Table).
