FDA Grants Xalkori Priority Review for Non-Small Cell Lung Cancer
Pfizer announced that the Food and Drug Administration (FDA) has accepted and granted Priority Review for a supplemental New Drug Application (sNDA) for Xalkori (crizotinib). Xalkori is a treatment for metastatic non-small cell lung cancer (NSCLC) patients whose tumors are ROS1-positive.
The sNDA submission was based on data from a multicenter, single-arm Phase 1 study, which evaluated Xalkori in 53 patients with ROS1-positive metastatic NSCLC. Data showed that Xalkori exhibited marked anti-tumor activity in these patients, with safety profile consistent with that observed in patients with anaplastic lymphoma kinase (ALK)-positive metastatic NSCLC.
The FDA granted Breakthrough Therapy designation to Xalkori for this potential indication in April 2015. If approved, Xalkori would become the first FDA-approved biomarker-driven therapy for the treatment of ROS1-positive metastatic NSCLC.
Xalkori is a kinase inhibitor currently indicated for the treatment of patients with metastatic NSCLC whose tumors are ALK-positive as detected by an FDA-approved test.For more information call (800) 438-1985 or visit Pfizer.com.
