Lorlatinib, sold under the brand name Lorbrena in the United States, Canada, and Japan, and Lorviqua in the European Union, is an anti-cancer drug developed by Pfizer. It is an orally administered inhibitor of ALK and ROS1, two enzymes that play a role in the development of cancer.[4]
Medical uses
Lorlatinib is approved in the US and in Europe for the second- or third-line treatment of ALK-positive metastatic non-small-cell lung cancer (NSCLC).[5][6][4] It is the only ALK inhibitor with meaningful activity against ALK G1202R mutation in lung cancer.[clarification needed][medical citation needed]

History
Clinical studies
This section needs to be updated.(September 2019) |
Several clinical trials were orchestrated. Lorlatinib was analyzed in a clinical trial[11] of 296 patients with ALK+ NSCLC whose cancer had migrated to multiple parts of the body including the brain. A trial comparing lorlatinib with crizotinib was conducted, with a primary endpoint of "progression-free survival", which is the period of time a patient is in remission (the tumor ceases growth). Preclinical studies are investigating lorlatinib for treatment of neuroblastoma.
In 2017, Pfizer announced that lorlatinib was shown to have activity against lung and brain tumors in people with ALK or ROS1 positive advanced non-small-cell lung cancer.[12]
Approval
In 2015, FDA granted Pfizer
