Tasigna (nilotinib) is a kinase inhibitor that interferes with a protein that signals cancer cells to multiply used to treat adult patients with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia in the chronic phase of the disease; it is also used to treat both chronic and accelerated Philadelphia chromosome positive myeloid leukemia in adults that are resistant or intolerant to prior therapy, including imatinib. Tasigna is available in generic form. Common side effects of Tasigna include:

  • skin rash,
  • itching,
  • headache,
  • nausea,
  • fatigue,
  • tiredness,
  • joint or muscle aches or pain,
  • back pain,
  • diarrhea,
  • constipation,
  • temporary hair loss, or
  • cold symptoms (stuffy nose, sneezing, cough, or sore throat).

Tell your doctor if you have serious side effects of Tasigna including:

Tasigna comes in a gelatin capsule at strengths of 150 and 200 mg. It is usually taken without food twice a day, at least 1 hour before or 2 hours after eating any food. The dosage is usually 300 mg per day, or 400 mg per day in those patients that are resistant or intolerant to prior therapy. However, because of the extensive and dire side effects in persons with underlying problems such as sudden death, hepatotoxicity, QT prolongation, myelosupression and other electrolyte and enzyme abnormalities, physicians often need to adjust the dose depending on several health factors; patients and physicians need to check the multiple tables available to develop a safe dose according to the patient's concurrent health problems and medications they take. Tasigna may interact with esomeprazole (Nexium) and other stomach acid reducers, ergotamine, dihydroergotamine, St. John's wort, theophylline, blood thinners or medication to prevent blood clots, antibiotics, tuberculosis medicine, antifungals, anti-malaria medication, cancer medication, immunosuppressants, medicine to prevent organ transplant rejection, heart or blood pressure medications, heart rhythm medications, medications to treat HIV/AIDS or hepatitis C, medicine to treat depression or mental illness, medicine to treat or prevent nausea, narcotics, sedatives, narcolepsy medication, seizure medication, or steroids. Tell your doctor all medications and supplements you use. Women who are pregnant should not take this drug; women who are breastfeeding should be cautioned that benefits to the mother must be weighed against the relatively unstudied risks to the infant. Safety and effectiveness of Tasigna use in pediatrics has not been established.

SIDE EFFECTS

The following serious adverse reactions can occur with Tasigna and are discussed in greater detail in other sections of labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In Adult Patients With Newly Diagnosed Ph+ CML-CP

The data below reflect exposure to Tasigna from a randomized trial in patients with newly diagnosed Ph+ CML in chronic phase treated at the recommended dose of 300 mg twice daily (n=279). The median time on treatment in the Tasigna 300 mg twice daily group was 61 months (range 0.1 to 71 months). The median actual dose intensity was 593 mg/day in the Tasigna 300 mg twice daily group.

The most common (greater than 10%) non-hematologic adverse drug reactions were rash, pruritus, headache, nausea, fatigue, alopecia, myalgia, and upper abdominal pain. Constipation, diarrhea, dry skin, muscle spasms, arthralgia, abdominal pain, peripheral edema, vomiting, and asthenia were observed less commonly (less than or equal to 10% and greater than 5%) and have been of mild-to-moderate severity, manageable and generally did not require dose reduction.

Increase in QTcF greater than 60 msec from baseline was observed in 1 patient (0.4%) in the 300 mg twice daily treatment group. No patient had an absolute QTcF of greater than 500 msec while on study drug.

The most common hematologic adverse drug reactions (all grades) were myelosuppression including: thrombocytopenia (18%), neutropenia (15%) and anemia (8%). See Table 9 for Grade 3/4 laboratory abnormalities.

Discontinuation due to adverse reactions, regardless of relationship to study drug, was observed in 10% of patients.

In Adult Patients With Resistant Or Intolerant Ph+ CML-CP And CML-AP

In the single open-label multicenter clinical trial, a total of 458 patients with Ph+ CML-CP and CML-AP resistant to or intolerant to at least one prior therapy including imatinib were treated (CML-CP=321; CML-AP=137) at the recommended dose of 400 mg twice daily.

The median duration of exposure in days for CML-CP and CML-AP patients is 561 (range 1 to 1096) and 264 (range 2 to 1160), respectively. The median dose intensity for patients with CML-CP and CML-AP is 789 mg/day (range 151 to 1110) and 780 mg/day (range 150 to 1149), respectively and corresponded to the planned 400 mg twice daily dosing.

The median cumulative duration in days of dose interruptions for the CML-CP patients was 20 (range 1 to 345), and the median duration in days of dose interruptions for the CML-AP patients was 23 (range 1 to 234).

In patients with CML-CP, the most commonly reported non-hematologic adverse drug reactions (greater than or equal to 10%) were rash, pruritus, nausea, fatigue, headache, constipation, diarrhea, vomiting and myalgia. The common serious drug-related adverse reactions (greater than or equal to 1% and less than 10%) were thrombocytopenia, neutropenia and anemia.

In patients with CML-AP, the most commonly reported non-hematologic adverse drug reactions (greater than or equal to 10%) were rash, pruritus and fatigue. The common serious adverse drug reactions (greater than or equal to 1% and less than 10%) were thrombocytopenia, neutropenia, febrile neutropenia, pneumonia, leukopenia, intracranial hemorrhage, elevated lipase and pyrexia.

Sudden deaths and QT prolongation were reported. The maximum mean QTcF change from baseline at steady-state was 10 msec. Increase in QTcF greater than 60 msec from baseline was observed in 4.1% of the patients and QTcF of greater than 500 msec was observed in 4 patients (less than 1%) [see BOXED WARNING, WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].

Discontinuation due to adverse drug reactions was observed in 16% of CML-CP and 10% of CML-AP patients.

Elevated total cholesterol (all grades) occurred in 28% (Tasigna 300 mg twice daily) and 4% (imatinib). Elevated triglycerides (all grades) occurred in 12% and 8% of patients in the Tasigna and imatinib arms, respectively. Hyperglycemia (all Grades) occurred in 50% and 31% of patients in the Tasigna and imatinib arms, respectively.

Most common biochemistry laboratory abnormalities (all grades) were alanine aminotransferase increased (72%), blood bilirubin increased (59%), aspartate aminotransferase increased (47%), lipase increased (28%), blood glucose increased (50%), blood cholesterol increased (28%), and blood triglyceride increased (12%).

Treatment Discontinuation In Ph+ CML-CP Patients Who Have Achieved A Sustained Molecular Response (MR4.5)

In eligible patients who discontinued Tasigna therapy after attaining a sustained molecular response (MR4.5), musculoskeletal symptoms (e.g. myalgia, pain in extremity, arthralgia, bone pain, spinal pain, or musculoskeletal pain), were reported more frequently than before treatment discontinuation in the first year, as noted in Table 10. The rate of new musculoskeletal symptoms generally decreased in the second year after treatment discontinuation.

In the newly diagnosed population in whom musculoskeletal symptoms occurred at any time during the TFR phase, 23/53 (43.4%) had not resolved by the TFR end date or data cut-off date. In the population previously treated with imatinib in whom musculoskeletal events occurred at any time during the TFR phase, 32/57 (56.1%) had not resolved by the data cut-off date.

The rate of musculoskeletal symptoms decreased in patients who entered the Tasigna treatment reinitiation (NTRI) phase, at 11/88 (12.5%) in the newly diagnosed population and 14/56 (25%) in the population previously treated with imatinib. Other adverse reactions observed in the Tasigna re-treatment phase were similar to those observed Tasigna use in patients with newly diagnosed Ph+ CML-CP and resistant or intolerant Ph+ CML-CP and CML-AP.

In Pediatric Patients With Newly Diagnosed Ph+ CML-CP Or Resistant Or Intolerant Ph+ CML-CP

The data below reflect exposure to Tasigna from two studies in pediatric patients from 2 to less than 18 years of age with either newly diagnosed Ph+ CML-CP or imatinib/dasatinib resistant or intolerant Ph+ CML-CP treated at the recommended dose of 230 mg/m² twice daily (n=69) [see Clinical Studies]. The median time on treatment with Tasigna was 13.8 months (range: 0.7 to 30.9 months). The median actual dose intensity was 435.5 mg/m²/day (range: 149 to 517 mg/m²/day), and the median relative dose intensity was 94.7% (range: 32 to 112%). Forty patients (58.0%) had relative dose intensity superior to 90%.

In pediatric patients with Ph+ CML-CP, the most common (greater than 20%) non-hematologic adverse drug reactions were headache, rash, hyperbilirubinemia, alanine aminotransferase increased, pyrexia, nausea, upper respiratory tract infection, aspartate aminotransferase increased, and vomiting. The most common (greater than 5%) Grade 3/4 non-hematologic adverse drug reactions were alanine aminotransferase increased and hyperbilirubinemia.

Laboratory abnormalities of hyperbilirubinemia (Grade 3/4: 13%) and transaminase elevation (AST Grade 3/4: 1%, ALT Grade 3/4: 9%), were reported at a higher frequency than in adult patients.

The most common hematological adverse drug reactions (greater than or equal to 30% of patients, of all grades) were decreases in total white blood cells (54%), platelet count (44%), absolute neutrophils (41%), absolute lymphocytes (32%), and hemoglobin (30%).

Discontinuation due to adverse reactions occurred in 9 patients (13%). The adverse reactions leading to discontinuation were hyperbilirubinemia (6%) and rash (4%).

Increase in QTcF greater than 30 msec from baseline was observed in 17 patients (25%). No patient had an absolute QTcF of greater than 500 msec or QTcF increase of greater than 60 msec from baseline.

Postmarketing Experience

The following adverse reactions have been identified during post approval use of Tasigna. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
