Beyond EGFR, ALK, and ROS1, there are a number of genomic subsets that have been of interest, particularly RET rearrangements, explains Drilon. RET rearrangements are fusions that are similar to ROS1, and occur in about 1% to 2% of NSCLC.
In 2016, there were 3 phase II studies, which demonstrated the response rate was anywhere from 15% to 50%, depending on the trial. The lesson there, according to Drilon, is that researchers are not quite seeing the same level of responses that are being seen with ALK and ROS1.
