EUCROSS is a phase II trial to evaluate the efficacy and safety of crizotinib in patients with adenocarcinoma of the lung harbouring ROS1 translocations. In individual treatment attempts and an ongoing phase I trial crizotinib has shown remarkable effects on this selected subgroup of lung cancer patients. Crizotinib is a tyrosine kinase inhibitor, blocking the catalytic activity of rearranged ALK and ROS1 as well as MET. The patients eligible for the trial will be treated with 250mg crizotinib twice-daily. Tumor response to treatment will be assessed every 6 weeks by CT or MRI scans. In case of progression treatment beyond may be conducted if clinically indicated. To identify mechanisms of resistance to crizotinib treatment, an optional re-biopsy may be performed in these cases and fresh frozen tumor material will analyzed at the University of Cologne.
