Title:
Entrectinib for ROS1-rearranged non-small cell lung cancer after crizotinib-induced interstitial lung disease: A case report
Published date:
10/04/2021
Excerpt:
We report an 85-year-old female patient with ROS1-rearranged NSCLC, who developed drug-induced interstitial lung disease (DI-ILD) 2 months after crizotinib treatment, and was treated with prednisolone followed by entrectinib. Entrectinib treatment resulted in stable disease with a marginal response after a partial response to crizotinib. Entrectinib treatment following crizotinib cessation due to DI-ILD was efficacious, which suggested that ROS1-G2032R gatekeeper mutation, frequently observed in crizotinib-resistant disease, was absent.
Secondary therapy:
prednisone

Title:
P12: Activity of gilteritinib in resistant ROS1 rearranged non-small cell lung cancer
Published date:
01/28/2022
Excerpt:
CONTRADICTING EVIDENCE: IC50 data summarized in the heatmap shows that ROS1 F2004C, ROS1 G2032R and ROS1 L2086F are entrectinib resistant. Cabozantinib, consistent with our previous published data harbors robust activity against ROS1 G2032R and ROS1 L2086F, however cabozantinib-resistance is imposed by ROS1F2004C mutation. Gilteritinib, intriguingly, is active with IC50 ≤ 25 nM against both ROS1 F2004C and ROS1 L2086F but not ROS1 G2032R.
