Tasigna Drug Information

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-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.

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%) . 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.

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 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). The median actual dose intensity was 427.7 mg/m 2 /day (range 149.1 to 492.8 mg/m 2 /day), and the median relative dose intensity was 93% (range, 32.4 to 107.1%). 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. Laboratory abnormalities of hyperbilirubinemia (Grade 3/4: 16%) and transaminase elevation (AST Grade 3/4: 2.9%, ALT Grade 3/4: 10%), were reported at a higher frequency than in adult patients. The most common hematological laboratory abnormalities (greater than or equal to 30% of patients, of all Grades) were decreases in total white blood cells (54%), platelet count (44%), absolute neutrophils (44%), hemoglobin (38%), and absolute lymphocytes (36%). 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). Of the 58 pediatric patients, five (9%) crossed two main percentile lines from baseline and three (5%) crossed three main percentile lines from baseline (percentile lines: 5 th, 10 th, 25 th, 50 th, 75 th, 90 th, and 95 th ). 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 2% to 4% and 15% to 20%, 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. At 30 mg/kg/day in rats and 300 mg/kg/day in rabbits, the maternal systemic exposure (AUC) were 72700 ng*hr/mL and 17100 ng*hr/mL, respectively, representing approximately 2 and 0.5 times the exposure in humans at the highest recommended dose 400 mg twice daily.

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). At doses up to 20 mg/kg (i.e., 120 mg/m 2, approximately 0.25 times the clinical dose of 400 mg twice daily based on body surface area) no adverse effects were seen in the maternal animals or the pups.

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 . The 25 patients with newly diagnosed Ph+ CML-CP were in the following age groups: 6 children (age 2 to less than 12 years) and 19 adolescents (age 12 to less than 18 years). The 44 patients with resistant or intolerant Ph+ CML-CP included 18 children (age 2 to less than 12 years) and 26 adolescents (age 12 to less than 18 years). All pediatric patients received Tasigna treatment at a dose of 230 mg/m 2 twice daily, rounded to the nearest 50 mg dose (to a maximum single dose of 400 mg). 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. 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.
