Pfizer Inc announced that the US Food and Drug Administration (FDA) has approved Lorbrena [lor-BREN-ah] (lorlatinib), a third-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) for patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on crizotinib and at least one other ALK inhibitor for metastatic disease; or whose disease has progressed on alectinib or ceritinib as the first ALK inhibitor therapy for metastatic disease. This indication is approved under accelerated approval based on tumour response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. This represents the third FDA approval Pfizer has received for an oncology treatment, including two lung cancer medicines, within two months.
Since Pfizer introduced XALKORI (crizotinib) as the first TKI for the treatment of ALK-positive metastatic NSCLC in 2011, the availability of these medicines has created an opportunity to provide patients with treatment options other than chemotherapy. However, lung cancer remains the leading cause of cancer-related death around the world.
