ROS1 positive | pancreatic cancer | predicted - sensitive | Entrectinib | Case Reports/Case Series | Actionable | In a Phase I trial, Rozlytrek (entrectinib) treatment resulted in stable disease in a patient with ROS1-positive pancreatic cancer (J Clin Oncol 32:5s, 2014 (suppl; abstr 2502)). | detail... |
ROS1 positive | lung non-small cell carcinoma | sensitive | Entrectinib | FDA approved | Actionable | In a combined analysis of 3 clinical trials (ALKA-372-001, STARTRK-1, STARTRK-2) that supported FDA approval, Rozlytrek (entrectinib) treatment resulted in an objective response rate of 77% (41/53), a median duration of response of 25 months in patients with ROS1 fusion positive non-small cell lung cancer, with median progression-free survival of 26 and 14 months for patients without (n=30) and with (n=23) CNS disease, respectively (Cancer Res 2019;79(13 Suppl):Abstract nr CT192; NCT02097810; NCT02568267). | detail... detail... |
