TASIGNA is a prescription medicine used to treat adults with newly diagnosed Philadelphia chromosome–positive chronic myeloid leukemia (Ph+ CML) in chronic phase. The efficacy of TASIGNA is based on major molecular response and cytogenetic response rates. The study is on-going and more data will be needed to determine long-term outcomes.
TASIGNA is also used to treat chronic phase or accelerated phase Philadelphia chromosome–positive chronic myeloid leukemia (Ph+ CML) in adults who are no longer benefiting from previous other treatments, including imatinib (GLEEVEC®), or have taken other treatments, including imatinib (GLEEVEC) but cannot tolerate them. The efficacy of TASIGNA is based on hematologic response and cytogenetic response rates.
In people with Ph+ CML, the bone marrow (the soft tissue inside bones where blood cells are made) produces too many white blood cells and these cells are often immature or damaged. TASIGNA is thought to work at the source of Ph+ CML by blocking the signal that causes your body to produce too many white blood cells.
Ph+ CML happens when an abnormal gene, called BCR-ABL, produces an abnormal protein called Bcr-Abl, which then leads to abnormalities in your body's process for making blood cells. The Bcr-Abl protein acts like a switch that keeps your white-blood cell production in the "on" position. Your bone marrow keeps making damaged white blood cells that, over time, crowd out healthy red blood cells and platelets.
TASIGNA may bind to the Bcr-Abl protein, which may block the signal that leads to the production of leukemic cells. Blocking the signal may lead to the death of leukemic cells and may help provide room for healthy blood cells to grow.
Even when test results show that TASIGNA is working, you may have levels of the Bcr-Abl protein in your blood that are not detectable by blood and bone marrow tests. If you stop taking TASIGNA or change your dose without speaking with your doctor, the abnormal protein could lead to the production of more leukemic cells. This is why it is so important you keep taking TASIGNA exactly as prescribed.
TASIGNA is thought to work similarly to GLEEVEC. GLEEVEC may bind to the Bcr-Abl protein, which may block the signal that causes your body to produce too many damaged white blood cells. However, over time, the Bcr-Abl protein can change or mutate. This can lead to GLEEVEC resistance, meaning that GLEEVEC no longer stops the signal that leads to the overproduction of damaged white blood cells. TASIGNA is thought to bind to some mutations of the Bcr-Abl protein that cause GLEEVEC resistance.
How TASIGNA Works
QT prolongation causes an irregular heartbeat, which may lead to sudden death.
Your doctor should check your heart with a test called an electrocardiogram (ECG):

IMPORTANT SAFETY INFORMATION ABOUT TASIGNA® (nilotinib)
What is the most important information to know about prescription TASIGNA?
TASIGNA can cause a possible life-threatening heart problem called QT prolongation.
QT prolongation causes an irregular heartbeat, which may lead to sudden death.
Your doctor should check your heart with a test called an electrocardiogram (ECG):
You may lower your chances for having QT prolongation with TASIGNA if you:
Who should not take TASIGNA?
Do not take if you have:
Taking TASIGNA:
Before taking TASIGNA
Talk to your doctor or pharmacist about all other medication(s) you may be taking, including prescription medicines, over-the-counter medicines, vitamins, and herbal supplements, since they may affect how TASIGNA works and increase your chance of serious and life-threatening side effects.
Tell your doctor if:
Also tell your doctor if you are pregnant, breast-feeding, or lactose-intolerant. The TASIGNA capsules contain lactose. Most patients who have mild or moderate lactose intolerance can take TASIGNA.
Serious side effects
TASIGNA may cause serious side effects including:
Your doctor may do blood tests to check you for TLS
Call your doctor immediately if you experience any of these symptoms. Your doctor may change your dose. Your doctor may have you stop TASIGNA for some time or lower your dose if you have side effects with it.
Common side effects
Most patients experience side effects at some time. Some common side effects you may experience include:
Be sure to tell your doctor or pharmacist if you have any side effects during treatment with TASIGNA. You are encouraged to report side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
It is not known if TASIGNA is safe or effective in children.
Tell your doctor if you are pregnant or planning to become pregnant. TASIGNA may harm your unborn baby. If you are able to become pregnant, you should use effective birth control during treatment with TASIGNA. Talk to your doctor about the best birth control methods to prevent pregnancy while you are taking TASIGNA.
Tell your doctor if you are breast-feeding or plan to breast-feed. It is not known if TASIGNA passes into your breast milk. You and your doctor should decide if you will take TASIGNA or breast-feed. You should not do both.
If you take too much TASIGNA, call your doctor or poison control center right away.
Your doctor will check your heart, do regular blood tests, and take bone marrow samples during treatment with TASIGNA. These are done to check for side effects with TASIGNA and to see how well TASIGNA is working for you. Your doctor should check your blood to monitor the amount of blood cells (white blood cells, red blood cells, and platelets) during treatment. These should be checked every 2 weeks for the first 2 months and then monthly thereafter, or as considered necessary by your doctor.
