Lorlatinib in ALK- or ROS1-positive non-small cell lung cancer patients: Experience from an early access program in Turkey

Background: Lorlatinib, a third generation ALK and ROS1 inhibitor, is indicated for the treatment of patients with ALK+ metastatic NSCLC whose disease has progressed on crizotinib and at least one second-generation ALK inhibitor. The aim of this study is to evaluate the efficacy and safety of lorlatinib in an Expanded Access Program (EAP) in Turkey. Method: The EAP was open-label, multicenter, and single-arm. Patients were eligible to receive lorlatinib (100 mg po/day) if they had advanced stage ALK-or ROS1-positive NSCLC and had progressed on crizotinib and/or second generation ALK inhibitors such as ceritinib or alectinib. The primary endpoint was PFS with lorlatinib. Secondary endpoints were objective response rate, overall survival, and safety.
