Xalkori® (crizotinib)

What is XALKORI® and what is it used for?

XALKORI® as monotherapy is indicated for1:         

  • The first-line treatment of adults with ALK-positive advanced NSCLC
  • The treatment of adults with previously treated ALK-positive advanced NSCLC
  • The treatment of adults with ROS1-positive advanced NSCLC

XALKORI® is a cancer medicine used on its own to treat adults with a type of lung cancer called non-small cell lung cancer (NSCLC), when the disease is advanced2:

  • It is used if the NSCLC is ‘ALK-positive’, which means that the cancer cells contain certain changes affecting the gene responsible for a protein called ALK (anaplastic lymphoma kinase).
  • It is also used when the NSCLC is ‘ROS1-positive’. This means that the cancer cells contain changes affecting the gene responsible for the protein ROS1.

ALK and ROS1 belong to a family of proteins called receptor tyrosine kinases (RTKs), which are involved in the growth of cells. In patients either ‘ALK-positive’ or ‘ROS1-positive’, the ALK or ROS1 protein is abnormally active and can promote the growth of cancer cells and the development of new blood vessels that supply them2.

The active substance in XALKORI®, crizotinib, is an RTK inhibitor. It works mainly by blocking the activity of ALK or ROS1, including when the genetic change is present, thereby reducing the growth and spread of the cancer in ALK-positive or in ROS1-positive NSCLC2.

The medicine can only be obtained with a prescription.
