name Xalkori when referring to the generic drug name Crizotinib.
Drug type: Xalkori capsules is a targeted therapy. It is
an oral receptor tyrosine kinase inhibitor - (For more detail, see "How this drug
What this drug is used for:
For the treatment of non-small cell lung cancer that is caused by a defect in a
gene called ALK (anaplastic lymphoma kinase). The cancer must be (ALK)-positive
as indicated by an FDA-approved test.
Note: If a drug has been approved for one use, physicians may elect to use
this same drug for other problems if they believe it may be helpful.
How this drug is given:

tells you to.
- If you miss a dose, take it as soon as you remember. If it is too close to your
next dose (within 6 hours), just take your next dose at your regular time.
- Do not take more than 1 dose of Xalkori capsules at one time. Call your health
care provider right away if you take too much.
- The amount of Xalkori capsules that you will receive depends on many factors,
your general health or other health problems, and the type of cancer or condition
being treated. Current recommendation is for one tablet twice daily, higher
doses do not give a better response and may cause increased toxicity. Your
doctor will determine your dose and schedule.

These side effects are less common side effects (occurring in about 10-29%) of patients
receiving Xalkori capsules:
A serious, but very uncommon side effect of Xalkori capsules is pneumonitis
(swelling of the lungs). When this side effect occurred, it was often accompanied

Monitoring and testing:
You will be checked regularly by your health care professional while you are taking
Xalkori capsules, to monitor side effects and check your response to therapy.
How this drug works:
Targeted therapy is the result of about 100 years of research dedicated to understanding
the differences between cancer cells and normal cells. To date, cancer treatment
has focused primarily on killing rapidly dividing cells because one feature of cancer
cells is that they divide rapidly. Unfortunately, some of our normal cells
divide rapidly too, causing multiple side effects.
Targeted therapy is about identifying other features of cancer cells. Scientists
look for specific differences in the cancer cells and the normal cells. This
information is used to create a targeted therapy to attack the cancer cells without
damaging the normal cells, thus leading to fewer side effects. Each type of
targeted therapy works a little bit differently but all interfere with the ability
of the cancer cell to grow, divide, repair and/or communicate with other cells.
There are different types of targeted therapies, defined in three broad categories.
Some targeted therapies focus on the internal components and function of the cancer
cell. The targeted therapies use small molecules that can get into the cell
and disrupt the function of the cells, causing them to die. There are several
types of targeted therapy that focus on the inner parts of the cells.
Other targeted therapies target receptors that are on the outside of the cell.
Therapies that target receptors are also known as monoclonal antibodies. Antiangiogenesis
inhibitors target the blood vessels that supply oxygen to the cells, ultimately
causing the cells to starve.
Xalkori capsules is a targeted therapy that targets and binds to the tyrosine kinase
receptors and inhibits ALK, Hepatocyte Growth Factor Receptor (HGFR, c-Met) and
Recepteur d’Origine Nantais (RON) on the surface of the cell. By binding to
these receptors Xalkori capsules blocks an important pathway that promotes
Research continues to identify which cancers may be best treated with targeted
therapies and to identify additional targets for more types of cancer.
