Background: Lorlatinib is a novel potent ALK inhibitor, with only a few studies reporting the results of its clinical use. Methods: This study describes the outcomes of lorlatinib treatment for 35 non-small cell lung cancer patients with ALK rearrangements, who had 2 ( n = 5), 1 ( n = 26) or none ( n = 4) prior tyrosine kinase inhibitors and received lorlatinib mainly within the compassionate use program. Results: Objective tumor response (OR) and disease control (DC) were registered in 15/35 (43%) and 33/35 (94%) patients, respectively; brain metastases were particularly responsive to the treatment (OR: 22/27 (81%); DC: 27/27 (100%)). Median progression free survival (PFS) was estimated to be 21.8 months, and median overall survival (OS) approached to 70.1 months. Only 4 out of 35 patients experienced no adverse effects; two of them were the only subjects who had no clinical benefit from lorlatinib. PFS and OS in the no-adverse-events lorlatinib users were strikingly lower as compared..... READ ARTICLE
