Entrectinib is a potent small-molecule inhibitor of the TRKA, TRKB, TRKC, ROS1, and ALK proteins.

Evidence (entrectinib):

A pooled analysis of three phase I/II trials evaluated the efficacy and safety of entrectinib in patients with metastatic or locally advanced or unresectable NTRK fusion−positive solid tumors. The efficacy analysis included 54 adult patients with advanced or metastatic NTRK fusion−positive solid tumors.[41]

The objective response rate was 57% (95% CI, 34.2%−70.8%). Seven percent of patients had a complete response, and 50% of patients had a partial response.[41][Level of evidence C2]

For the five patients with thyroid cancer, the overall response rate was 20% (95% CI, 1%−72%).
