Jan 01, 2015 · Results. We identified multiple novel crizotinib resistance mutations in the ROS1 kinase domain including the G2032R mutation. As the result of high-throughput drug screening, we found that the cMET/RET/VEGFR inhibitor cabozantinib XL184 effectively inhibited the survival of CD74-ROS1-WT and resistant mutants harboring Ba/F3 and MGH047 cells. We will also review emerging therapies in ROS1 positive NSCLC, including cabozantinib, lorlatinib, entrectinib, and ceritinib. Expert commentary: Targeted therapy in ROS1 positive NSCLC has resulted in improved clinical outcomes compared with traditional chemotherapy. Thus, it is essential to screen for ROS1 fusions in NSCLC patients.

ROS1 positive lung cancer is a lung tumor that tests positive for a ROS1 gene rearrangement, one of the known "driver mutations" found in lung cancer. ROS1 positive lung cancer accounts for only one percent to two percent of lung cancers. But, considering how common lung cancer is, it still represents many people with this disease.
ROS1 is a validated therapeutic target in NSCLC.

Apr 02, 2013 · Activated RET and ROS: two new driver mutations in lung adenocarcinoma. This review will focus on RET- and ROS1 kinases, their physiological role in the cell and their function as an oncogenic driver especially in lung adenocarcinoma. For instance, cabozantinib showed greater activity compared to vandetanib in cells harboring the RET. Jun 25, 2018 · ROS1-Rearranged NSCLC The ROS1-rearrangement was discovered in lung cancer around the same time as ALK in 2007. This receptor tyrosine kinase fusion is also seen in other tumor types such as brain. May 15, 2016 · Cabozantinib administration. The patient received cabozantinib at a dose of 60 mg daily in 28-day cycles as part of an ongoing phase II clinical trial NCT01639508 with an arm for ROS1-rearranged lung cancers.Inclusion criteria for patients in this trial were as follows: pathologic or cytologic evidence of non–small cell lung cancer NSCLC, clinical stage IV or recurrent/medically.
Cabozantinib is an oral small-molecule tyrosine kinase inhibitor. In vitro biochemical and/or cellular assays have shown that cabozantinib inhibits the tyrosine kinase activity of MET, vascular endothelial growth factor receptor 1 VEGFR1, VEGFR2, VEGFR3, AXL, RET, ROS1.

INTRODUCTION. There has been a decrease in the number of incidences of lung cancer recorded among men over the past few decades as well as among women in the last decade, 1 which has been attributed to the advances in screening methods, surgical and radiation techniques, and new therapeutic modalities. In non-small cell lung cancer NSCLC, many targetable receptors or protein kinases linked.
Lorlatinib showed clinical activity in patients with advanced ROS1-positive NSCLC, including those with CNS metastases and those previously treated with crizotinib. Because crizotinib-refractory patients have few treatment options, lorlatinib could represent an important next-line targeted agent. Jul 27, 2018 · Up to 50% of lung tumors harboring ROS1 fusion genes treated with crizotinib develop a secondary mutation, ROS1 G2032R, in the kinase domain. 8 Several next‐generation ROS1 inhibitors have been developed for patients with lung cancers harboring ROS1 fusion genes. 22 Preclinical studies showed that lorlatinib, foretinib and cabozantinib can.
