...Pts with advanced solid tumors with molecular alterations in TrkA, ROS1 or ALK were treated in Sch B (QD) or Sch C (4d on/3d off)...Entrectinib is well tolerated. The majority of pts reported G1/ G2 AEs. 13 pts reported ≥ G3 AEs….In this trial with entrectinib administered in 3 different dosing schedules, significant antitumor response was observed in pts with relevant molecular alterations, notably ROS1 rearranged NSCLC at doses ≥ 400 mg/m2/day and the only NTRK1 rearranged pt treated to date.
