Key clinical point : Anticoagulant use is linked to worse progression-free survival (PFS) and objective response rate (ORR) in patients with ALK- and ROS1-rearranged advanced nonsmall cell lung cancer (NSCLC) treated with crizotinib.
Major finding : In the ROS1-rearranged group, anticoagulant use vs no use was associated with a shorter median PFS (5.1 vs 29 months) and poorer ORR (41.7% vs 80.5%). Similarly, in the ALK-rearranged group, anticoagulant use vs no use was associated with a shorter median PFS (7.1 vs 12 months) and poorer ORR (41% vs 74.3%).
Study details : The data come from a retrospective analysis of patients with ROS1- and ALK-rearranged advanced NSCLC (n = 206) who received crizotinib in the phase 1 PROFILE 1001 trial.
Disclosures: The study was funded by Pfizer. The authors reported receiving grants or personal fees from one or more pharmaceutical companies, including Pfizer, outside this work.
