Tasigna Drug Information

Recommended Dosage Dose

Tasigna twice daily at approximately 12-hour intervals on an empty stomach. No food should be consumed for at least 2 hours before the dose is taken and for at least 1 hour after the dose is taken. Advise patients to swallow the capsules whole with water.

For patients who are unable to swallow capsules, the contents of each capsule may be dispersed in 1 teaspoon of applesauce (puréed apple). The mixture should be taken immediately (within 15 minutes) and should not be stored for future use. Tasigna may be given in combination with hematopoietic growth factors, such as erythropoietin or G-CSF if clinically indicated.

Tasigna may be given with hydroxyurea or anagrelide if clinically indicated. Dosage in Adult Patients with Newly Diagnosed Ph+ CML-CP The recommended dosage of Tasigna is 300 mg orally twice daily. Dosage in Adult Patients with Resistant or Intolerant Ph+ CML-CP and CML-AP The recommended dosage of Tasigna is 400 mg orally twice daily.

If needed, attain the desired dose by combining different strengths of Tasigna capsules. Continue treatment as long as clinical benefit is observed or until unacceptable toxicity occurs. Table 1: Pediatric Dosing of Tasigna 230 mg/m 2 Twice Daily, Maximum Single Dose of

Discontinuation of Treatment After a Sustained Molecular Response (MR4.5) on Tasigna Patient Selection Eligibility for Discontinuation of Treatment Ph+ CML-CP patients with typical BCR-ABL transcripts, who have been taking Tasigna for a minimum of 3 years and have achieved a sustained molecular response (MR4.5, corresponding to = BCR-ABL/ABL ≤ 0.0032% IS), may be eligible for treatment discontinuation. Information on FDA authorized tests for the detection and quantitation of BCR-ABL transcripts to determine eligibility for treatment discontinuation is available at http://www.fda.gov/CompanionDiagnostics. Patients with typical BCR-ABL transcripts (e13a2/b2a2 or e14a2/b3a2), who achieve the sustained MR4.5 criteria, are eligible for discontinuation of Tasigna.

Patients must continue to be monitored for possible loss of molecular remission after treatment discontinuation. Use the same FDA-authorized test to consistently monitor molecular response levels while on and off treatment. Consider discontinuation in patients with newly diagnosed Ph+ CML-CP who have: been treated with Tasigna for at least 3 years maintained a molecular response of at least MR4.0 (corresponding to = BCR-ABL/ABL ≤ 0.01% IS) for one year prior to discontinuation of therapy achieved an MR4.5 for the last assessment taken immediately prior to discontinuation of therapy been confirmed to express the typical BCR-ABL transcripts (e13a2/b2a2 or e14a2/b3a2) no history of accelerated phase or blast crisis no history of prior attempts of treatment-free remission discontinuation that resulted in relapse.

Consider discontinuation in patients with Ph+ CML-CP that are resistant or intolerant to imatinib who have achieved a sustained molecular response (MR4.5) on Tasigna who have: been treated with Tasigna for a minimum of 3 years been treated with imatinib only prior to treatment with Tasigna achieved a molecular response of MR4.5 (corresponding to = BCR-ABL/ABL ≤ 0.0032% IS) sustained an MR4.5 for a minimum of one year immediately prior to discontinuation of therapy been confirmed to express the typical BCR-ABL transcripts (e13a2/b2a2 or e14a2/b3a2) no history of accelerated phase or blast crisis no history of prior attempts of treatment-free remission discontinuation that resulted in relapse. Monitor BCR-ABL transcript levels and complete blood count (CBC) with differential in patients who have discontinued Tasigna therapy monthly for one year, then every 6 weeks for the second year, and every 12 weeks thereafter. Upon the loss of MR4.0 (corresponding to = BCR-ABL/ABL ≤ 0.01% IS) during the treatment-free phase, monitor BCR-ABL transcript levels every 2 weeks until BCR-ABL levels remain lower than major molecular response for 4 consecutive measurements.

The patient can then proceed to the original monitoring schedule.

Reinitiation of Treatment in Patients Who Lose Molecular Response After Discontinuation of Therapy With Tasigna Newly diagnosed patients who lose MMR must reinitiate treatment within 4 weeks at the dose level prior to discontinuation of therapy. Patients who reinitiate Tasigna therapy should have their BCR-ABL transcript levels monitored monthly until major molecular response is re-established and every 12 weeks thereafter. Patients resistant or intolerant to prior treatment that included imatinib with confirmed loss of MR4.0 (2 consecutive measures separated by at least 4 weeks showing loss of MR4.0) or loss of MMR must reinitiate treatment within 4 weeks at the dose level prior to discontinuation of therapy.

Dosage Modification for QT Interval Prolongation See Table 2 for dose adjustments for QT interval prolongation. Table 2: Dosage Adjustments for Adult and Pediatric Patients With QT Prolongation

Dosage Modifications for Myelosuppression Withhold or reduce

Tasigna dosage for hematological toxicities (neutropenia, thrombocytopenia) that are not related to underlying leukemia (Table 3). Table 3: Dosage Adjustments for Neutropenia and Thrombocytopenia

Dosage Modifications for Selected Non-Hematologic Laboratory Abnormalities and Other Toxicities See Table 4 for dosage adjustments for elevations of lipase, amylase, bilirubin, and/or hepatic transaminases. Table 4: Dosage Adjustments for Selected Non-Hematologic Laboratory Abnormalities If clinically significant moderate or severe non-hematologic toxicity develops (including medically severe fluid retention), see Table 5 for dosage adjustments. Table 5: Dosage Adjustments for Other Non-Hematologic Toxicities

Dosage Modification for Hepatic Impairment

If possible, consider alternative therapies. If Tasigna must be administered to patients with hepatic impairment, consider the following dose reduction: Table 6: Dose Adjustments for Adult Patients With Hepatic Impairment

Dosage Modification With Concomitant Strong CYP3A4 Inhibitors Avoid the concomitant use of strong CYP3A4 inhibitors. Should treatment with any of these agents be required, interrupt therapy with Tasigna. If patients must be coadministered a strong CYP3A4 inhibitor, reduce dosage to 300 mg once daily in patients with resistant or intolerant Ph+ CML or to 200 mg once daily in patients with newly diagnosed Ph+ CML-CP.

However, there are no clinical data with this dose adjustment in patients receiving strong CYP3A4 inhibitors. If the strong inhibitor is discontinued, allow a washout period before adjusting Tasigna dose upward to the indicated dose. For patients who cannot avoid use of strong CYP3A4 inhibitors, monitor closely for prolongation of the QT interval.

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 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. 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-arm, 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. 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.

Sudden deaths and QT prolongation were reported. The maximum mean QTcF change from baseline at steady-state was 10 msec. Discontinuation due to adverse drug reactions was observed in 16% of CML-CP and 10% of CML-AP patients.

Most Frequently Reported Adverse Reactions Tables 7 and 8 show the percentage of adult patients experiencing non-hematologic adverse reactions (excluding laboratory abnormalities) regardless of relationship to study drug. Adverse reactions reported in greater than 10% of adult patients who received at least 1 dose of Tasigna are listed. Table 7: Most Frequently Reported Non-Hematologic Adverse Reactions (Regardless of Relationship to Study Drug) in Adult Table 8: Most Frequently Reported Non-Hematologic Adverse Reactions in Adult Patients With Resistant or Intolerant Ph+ CML Receiving Tasigna 400 mg Twice Daily (regardless of relationship to study drug) greater than or equal to Laboratory Abnormalities Table 9 shows the percentage of adult patients experiencing treatment-emergent Grade 3/4 laboratory abnormalities in patients who received at least one dose of Tasigna.

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 .

Treatment Discontinuation in Patients With Ph+ CML-CP 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%) 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%) 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 (13%) 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 during 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/m 2 twice daily (n = 69). The median time on treatment with Tasigna was 39.6 months (range, 0.7 to 63.5 months).

Thirty-nine patients (57%) had relative dose intensity superior to 90%. In pediatric patients with Ph+ CML-CP, the most common (greater than 20%) non-hematologic adverse reactions were hyperbilirubinemia, headache, alanine aminotransferase increased, rash, pyrexia, nausea, aspartate aminotransferase increased, pain in extremity, upper respiratory tract infection, vomiting, diarrhea, and nasopharyngitis. The most common (greater than 5%) Grade 3/4 non-hematologic adverse reactions were hyperbilirubinemia, rash, alanine aminotransferase increased, and neutropenia.

Discontinuation of study treatment due to adverse reactions occurred in 15 patients (22%). The most frequent adverse reactions leading to discontinuation were hyperbilirubinemia (9%) and rash (6%). Increase in QTcF greater than 30 msec from baseline was observed in 19 patients (28%).

No patient had an absolute QTcF of greater than 500 msec or QTcF increase of greater than 60 msec from baseline. Growth Retardation in Pediatric Population In a multicenter, open-label, single-arm study of 58 pediatric patients with newly diagnosed or resistant Ph+ CML-CP treated with Tasigna, with a median exposure of 56.7 months, adverse reactions associated with growth and deceleration of growth in regard to height were reported in 3 patients (5%). The adverse reactions include growth retardation in 2 adolescent patients and growth hormone deficiency with short stature in the remaining patient (age category: child).

Close monitoring of growth in pediatric patients under Tasigna treatment is recommended.

Postmarketing Experience

The following adverse reactions have been identified during postapproval 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. Blood and Lymphatic System Disorders: thrombotic microangiopathy Nervous System Disorders: facial paralysis Musculoskeletal and Connective Tissue Disorders: osteonecrosis

Tumor Lysis Syndrome Tumor lysis syndrome (TLS) cases have been reported in Tasigna treated patients with resistant or intolerant CML. Malignant disease progression, high white blood cell (WBC) counts and/or dehydration were present in the majority of these cases. Due to potential for TLS, maintain adequate hydration and correct uric acid levels prior to initiating therapy with Tasigna.

Pregnancy Risk Summary Based on findings from animal studies and the mechanism of action, Tasigna can cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of nilotinib to pregnant rats and rabbits during organogenesis caused adverse developmental outcomes, including embryo-fetal lethality, fetal effects, and fetal variations in rats and rabbits at maternal exposures (AUC) approximately 2 and 0.5 times, respectively, the exposures in patients at the recommended dose ( see Data ).

Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are respectively. Data Animal Data In embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of nilotinib up to 100 mg/kg/day and 300 mg/kg/day, respectively, during the period of organogenesis. In rats, oral administration of nilotinib produced embryo-lethality/fetal effects at doses ≥ 30 mg/kg/day.

At ≥ 30 mg/kg/day, skeletal variations of incomplete ossification of the frontals and misshapen sternebra were noted, and there was an increased incidence of small renal papilla and fetal edema. At 100 mg/kg/day, nilotinib was associated with maternal toxicity (decreased gestation weight, gravid uterine weight, net weight gain, and food consumption) and resulted in a single incidence of cleft palate and two incidences of pale skin were noted in the fetuses. A single incidence of dilated ureters was noted in a fetus also displaying small renal papilla at 100 mg/kg/day.

Additional variations of forepaw and hindpaw phalanx unossified, fused sternebra, bipartite sternebra ossification, and incomplete ossification of the cervical vertebra were noted at 100 mg/kg/day. In rabbits, oral administration of nilotinib resulted in the early sacrifice of two females, maternal toxicity and increased resorption of fetuses at 300 mg/kg/day. Fetal skeletal variations (incomplete ossification of the hyoid, bent hyoid, supernumerary short detached ribs and the presence of additional ossification sites near the nasals, frontals and in the sternebral column) were also increased at this dose in the presence of maternal toxicity.

Slight maternal toxicity was evident at 100 mg/kg/day but there were no reproductive or embryo-fetal effects at this dose. When pregnant rats were dosed with nilotinib during organogenesis and through lactation, the adverse effects included a longer gestational period, lower pup body weights until weaning and decreased fertility indices in the pups when they reached maturity, all at a maternal dose of 60 mg/kg (i.e., 360 mg/m 2, approximately 0.7 times the clinical dose of 400 mg twice daily based on body surface area).

Pediatric Use The safety and effectiveness of Tasigna have been established in pediatric patients greater than or equal to 1 year of age with newly diagnosed and resistant or intolerant Ph+ CML in chronic phase. There are no data for pediatric patients under 2 years of age. Use of Tasigna in pediatric patients 1 year to less than 2 years of age with newly diagnosed or resistant or intolerant Ph+ CML in chronic phase is supported by efficacy in pediatric patients 2 to 6 years of age for these indications.

The safety and effectiveness of Tasigna have been established in pediatric patients greater than or equal to 1 year of age with resistant or intolerant Ph+ CML in accelerated phase based on evidence of effectiveness from an adequate and well-controlled single-arm study in adults with safety data from two pediatric studies as described in the next paragraph. Use of Tasigna in pediatric patients 1 to less than 18 years of age is supported by evidence from two clinical trials. No differences in efficacy or safety were observed between the different age subgroups in the two trials.

The frequency, type, and severity of adverse reactions observed were generally consistent with those observed in adults, with the exception of the laboratory abnormalities of hyperbilirubinemia (Grade 3/4: 16%) and transaminase elevation (AST Grade 3/4: 2.9%, ALT Grade 3/4: 10%), which were reported at a higher frequency in pediatric patients than in adults. For pediatric growth and development, growth retardation has been reported in pediatric patients with Ph+ CML-CP treated with Tasigna. The safety and effectiveness of Tasigna in pediatric patients below the age of 1 year with newly diagnosed, or resistant or intolerant Ph+ CML in chronic phase and accelerated phase, have not been established.

Tasigna is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome.

Overdose with nilotinib has been reported, where an unspecified number of Tasigna capsules were ingested in combination with alcohol and other drugs. Events included neutropenia, vomiting, and drowsiness. In the event of overdose, observe the patient and provide appropriate supportive treatment.
