  • BOXED WARNING (What is this?)

    WARNING: RENAL FAILURE, HEPATIC FAILURE, AND GASTROINTESTINAL HEMORRHAGE


    Renal Failure
        Deferasirox tablets for oral suspension can cause acute renal failure and death, particularly in patients with comorbidities and those who are in the advanced stages of their hematologic disorders.
        Evaluate baseline renal function prior to starting or increasing deferasirox tablets for oral suspension dosing in all patients. Deferasirox tablets for oral suspension are contraindicated in adult and pediatric patients with eGFR less than 40 mL/min/1.73 m2. Measure serum creatinine in duplicate prior to initiation of therapy. Monitor renal function at least monthly. For patients with baseline renal impairment or increased risk of acute renal failure, monitor renal function weekly for the first month, then at least monthly. Reduce the starting dose in patients with preexisting renal disease. During therapy, increase the frequency of monitoring and modify the dose for patients with an increased risk of renal impairment, including use of concomitant nephrotoxic drugs, and pediatric patients with volume depletion or overchelation [see Dosage and Administration (2.1, 2.4, 2.5), Warnings and Precautions (5.1), Adverse Reactions (6.1, 6.2)].

    Hepatic Failure
        Deferasirox tablets for oral suspension can cause hepatic injury including hepatic failure and death.
         Measure serum transaminases and bilirubin in all patients prior to initiating treatment, every 2 weeks during the first month, and at least monthly thereafter.
        Avoid use of deferasirox tablets for oral suspension in patients with severe (Child-Pugh C) hepatic impairment and reduce the dose in patients with moderate (Child-Pugh B) hepatic impairment [see Dosage and Administration (2.4), Warnings and Precautions (5.2)].

    Gastrointestinal Hemorrhage
     Deferasirox tablets for oral suspension can cause gastrointestinal (GI) hemorrhages, which may be fatal, especially in elderly patients who have advanced hematologic malignancies and/or low platelet counts.
    Monitor patients and discontinue deferasirox tablets for oral suspension for suspected GI ulceration or hemorrhage [see Warnings and Precautions (5.3)].

  • 1 INDICATIONS  AND  USAGE

    1.1 Treatment of Chronic Iron Overload Due to Blood Transfusions (Transfusional Iron Overload)

    Deferasirox tablets for oral suspension are indicated for the treatment of chronic iron overload due to blood transfusions (transfusional hemosiderosis) in patients 2 years of age and older.

    Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    1.3 Limitations of Use

    The safety and efficacy of deferasirox tablets for oral suspension when administered with other iron chelation therapy have not been established.

  • 2 DOSAGE  AND  ADMINISTRATION

    2.1 Transfusional Iron Overload

    Deferasirox tablets for oral suspension therapy should only be considered when a patient has evidence of chronic transfusional iron overload. The evidence should include the transfusion of at least 100 mL/kg of packed red blood cells (e.g., at least 20 units of packed red blood cells for a 40 kg person or more in individuals weighing more than 40 kg), and a serum ferritin consistently greater than 1000 mcg/L.

    Prior to starting therapy or increasing dose, evaluate:
     Serum ferritin level
     Baseline renal function:
           o Obtain serum creatinine in duplicate (due to variations in measurements) to establish accurate baseline
           o Calculate the estimated glomerular filtration rate (eGFR). Use a prediction equation appropriate for adult patients (e.g., CKD-EPI, MDRD method) and in pediatric patients    (e.g., Schwartz equations).
           o Obtain urinalyses and serum electrolytes to evaluate renal tubular function [see Dosage and Administration (2.4), Warnings and Precautions (5.1)]
     Serum transaminases and bilirubin [see Dosage and Administration (2.4), Warnings and Precautions (5.2)]
     Baseline auditory and ophthalmic examinations [see Warnings and Precautions (5.10)]

     Initiating Therapy:
    The recommended initial dose of deferasirox tablets for oral suspension for patients 2 years of age and older with eGFR greater than 60 mL/min/1.73 m2 is 20 mg per kg body weight orally, once daily. Calculate doses (mg per kg per day) to the nearest whole tablet.

    During therapy:
     Monitor serum ferritin monthly and adjust the dose of deferasirox tablets for oral suspension, if necessary, every 3 to 6 months based on serum ferritin trends.
     Use the minimum effective dose to achieve a trend of decreasing ferritin.
     Make dose adjustments in steps of 5 or 10 mg per kg and tailor adjustments to the individual patient’s response and therapeutic goals.
     In patients not adequately controlled with doses of 30 mg per kg (e.g., serum ferritin levels persistently above 2,500 mcg/L and not showing a decreasing trend over time), doses of up to 40 mg per kg may be considered. Doses above 40 mg per kg are not recommended [see Warnings and Precautions (5.6)].
     Adjust dose based on serum ferritin levels
            o If the serum ferritin falls below 1000 mcg/L at 2 consecutive visits, consider dose reduction, especially if the dose is greater than 25 mg/kg/day [see Adverse Reactions (6.1)].
           o If the serum ferritin falls below 500 mcg/L, interrupt deferasirox tablets for oral suspension and continue monthly monitoring.
           o Evaluate the need for ongoing chelation therapy for patients whose conditions no longer require regular blood transfusions.
            o Use the minimum effective dose to maintain iron burden in the target range [see Warnings and Precautions (5.6)].
     Monitor blood counts, liver function, renal function and ferritin monthly [see Warnings and Precautions (5.1, 5.2, 5.4)].
     Interrupt deferasirox tablets for oral suspension for pediatric patients who have acute illnesses, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake, and monitor more frequently. Resume therapy as appropriate, based on assessments of renal function, when oral intake and volume status are normal [see Dosage and Administration (2.4, 2.5), Warnings and Precautions (5.1), Use in Specific Populations (8.4), Clinical Pharmacology (12.3)].

    Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.


    2.3 Administration

    Do not chew tablets or swallow them whole.


    Take deferasirox tablets for oral suspension once daily on an empty stomach at least 30 minutes before food, preferably at the same time each day. Completely disperse tablets by stirring in water, orange juice, or apple juice until a fine suspension is obtained. Disperse doses of less than 1 g in 3.5 ounces of liquid and doses of 1 g or greater in 7 ounces of liquid. After swallowing the suspension, resuspend any residue in a small volume of liquid and swallow. Do not take deferasirox tablets for oral suspension with aluminum-containing antacid products [see Drug Interactions (7.1)].

    2.4 Use in Patients with Baseline Hepatic or Renal Impairment

    Patients with Baseline Hepatic Impairment

    Mild (Child-Pugh A) Hepatic Impairment: No dose adjustment is necessary.

    Moderate (Child-Pugh B) Hepatic Impairment: Reduce the starting dose by 50%.

    Severe (Child-Pugh C) Hepatic Impairment: Avoid deferasirox tablets for oral suspension [see Warnings and Precautions (5.2), Use in Specific Populations (8.7)].

    Patients with Baseline Renal Impairment

    Do not use deferasirox tablets for oral suspension in adult or pediatric patients with eGFR less than 40 mL/min/1.73 m2[see Dosage and Administration (2.5), Contraindications (4)].

    For patients with renal impairment (eGFR 40 to 60 mL/min/1.73 m2), reduce the starting dose by 50% [see Use in Specific Populations (8.6)].


    Exercise caution in pediatric patients witheGFR between 40 and 60 mL/min/1.73 m2. If treatment is needed, use the minimum effective dose and monitor renal function frequently. Individualize dose titration based on improvement in renal injury [see Use in Specific Populations (8.6)].



    2.5 Dose Modifications for Decreases in Renal Function while on Deferasirox Tablets for Oral Suspension

    Deferasirox tablets for oral suspension is contraindicated in patients with eGFR less than 40 mL/min/1.73 m2 [see Contraindications (4)].


    For decreases in renal function while receiving deferasirox tablets for oral suspension [see Warnings and Precautions (5.1)], modify the dose as follows:

    Transfusional Iron  Overload

    Adults:

    • If the serum creatinine increases by 33% or more above the average baseline measurement, repeat the serum creatinine within 1 week, and if still elevated by 33% or more, reduce the dose by 10 mg per kg.

    Pediatric Patients (ages 2 to 17 years):

    • Reduce the dose by 10 mg/per/kg if eGFR decreases by greater than 33% below the average baseline measurement andrepeat the eGFR within 1 week.
    • Interrupt deferasirox tablets for oral suspension for acute illnesses, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake, and monitor more frequently. Resume therapy as appropriate, based on assessments of renal function, when oral intake and volume status are normal. Avoid use of other nephrotoxic drugs [see Warnings and Precautions (5.1)]. 
    • In the setting of decreased renal function, evaluate the risk benefit profile of continued deferasirox tablets for oral suspension use. Use the minimum effective deferasirox tablets for oral suspension dose and monitor renal function more frequently, by evaluating tubular and glomerular function. Titrate dosing based on renal injury. Consider dose reduction or interruption and less nephrotoxic therapies until improvement of renal function. If signs of renal tubular or glomerular injury occur in the presence of other risk factors such as volume depletion, reduce or interrupt deferasirox tablets for oral suspension to prevent severe and irreversible renal injury [see Warnings and Precautions (5.1)].

     All Patients (regardless of age):

    • Discontinue therapy for eGFR less than 40 mL/min/1.73m2[see Contraindications (4)].

     Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    2.6 Dose Modifications Based on Concomitant Medications

    UDP-glucuronosyltransferases (UGT) Inducers

    Concomitant use of UGT inducers decreases deferasirox tablets for oral suspension systemic exposure. Avoid the concomitant use of potent UGT inducers (e.g., rifampicin, phenytoin, phenobarbital, ritonavir) with deferasirox tablets for oral suspension. If you must administer deferasirox tablets for oral suspension with 1 of these agents, consider increasing the initial dose of deferasirox tablets for oral suspension by 50%, and monitor serum ferritin levels and clinical responses for further dose modification [see Dosage and Administration (2.1), Drug Interactions (7.5)].


    Bile Acid Sequestrants

    Concomitant use of bile acid sequestrants decreases deferasirox tablets for oral suspension systemic exposure. Avoid the concomitant use of bile acid sequestrants (e.g., cholestyramine, colesevelam, colestipol) with deferasirox tablets for oral suspension. If you must administer deferasirox tablets for oral suspension with 1 of these agents, consider increasing the initial dose of deferasirox tablets for oral suspension by 50%, and monitor serum ferritin levels and clinical responses for further dose modification [see Dosage and Administration (2.1), Drug Interactions (7.6)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Acute Kidney Injury, Including Acute Renal Failure Requiring Dialysis, and Renal Tubular Toxicity Including Fanconi Syndrome

    Deferasirox tablets for oral suspension are contraindicated in patients with eGFR less than 40 mL/min/1.73 m2. Exercise caution in pediatric patients with eGFR between 40 and 60 mL/minute/1.73 m2. If treatment is needed, use the minimum effective dose and monitor renal function frequently. Individualize dose titration based on improvement in renal injury [see Use in Specific Populations (8.6)]. For patients with renal impairment (eGFR 40 to 60 mL/min/1.73 m2) reduce the starting dose by 50% [see Dosage and Administration (2.4, 2.5), Use in Specific Populations (8.6)].


    Deferasirox tablets for oral suspension can cause acute kidney injury including renal failure requiring dialysis that has resulted in fatal outcomes. Based on postmarketing experience, most fatalities have occurred in patients with multiple comorbidities and who were in advanced stages of their hematological disorders. In the clinical trials, adult and pediatric deferasirox tablets for oral suspension-treated patients with no preexisting renal disease experienced dose-dependent mild, non-progressive increases in serum creatinine and proteinuria. Preexisting renal disease and concomitant use of other nephrotoxic drugs may increase the risk of acute kidney injury in adult and pediatric patients. Acute illnesses associated with volume depletion and overchelation may increase the risk of acute kidney injury in pediatric patients. In pediatric patients, small decreases in eGFR can result in increases in deferasirox tablets for oral suspension exposure, particularly in younger patients with body surface area typical of patients less than age 7 years. This can lead to a cycle of worsening renal function and further increases in deferasirox tablets for oral suspension exposure, unless the dose is reduced or interrupted. Renal tubular toxicity, including acquired Fanconi syndrome, has been reported in patients treated with deferasirox tablets for oral suspension, most commonly in pediatric patients with beta-thalassemia and serum ferritin levels less than 1,500 mcg/L [see Warnings and Precautions (5.6), Adverse Reactions (6.1, 6.2), Use in Special Populations (8.4), Clinical Pharmacology (12.3) ].


    Evaluate renal glomerular and tubular function before initiating therapy or increasing the dose. Use prediction equations validated for use in adult and pediatric patients to estimate GFR. Obtain serum electrolytes and urinalysis in all patients to evaluate renal tubular function [see Dosage and Administration (2.1)].


    Monitor all patients for changes in eGFR and for renal tubular toxicity weekly during the first month after initiation or modification of therapy and at least monthly thereafter. Monitor serum ferritin monthly to evaluate for overchelation. Use the minimum dose to establish and maintain a low iron burden. Monitor renal function more frequently in patients with preexisting renal disease or decreased renal function. In pediatric patients, interrupt deferasirox tablets for oral suspension during acute illnesses, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake, and monitor renal function more frequently. Promptly correct fluid deficits to prevent renal injury. Resume therapy as appropriate, based on assessments of renal function, when oral intake and volume status are normal [see Dosage and Administration (2.5), Warnings and Precautions (5.6), Adverse Reactions (6.1, 6.2), Use in Specific Populations (8.4)].

    5.2 Hepatic Toxicity and Failure

    Deferasirox tablets for oral suspension can cause hepatic injury, fatal in some patients. In Study 1, 4 patients (1.3%) discontinued deferasirox tablets for oral suspension because of hepatic toxicity (drug-induced hepatitis in 2 patients and increased serum transaminases in 2 additional patients). Hepatic toxicity appears to be more common in patients greater than 55 years of age. Hepatic failure was more common in patients with significant comorbidities, including liver cirrhosis and multiorgan failure [see Adverse Reactions (6.1)]. Acute liver injury and failure, including fatal outcomes, have occurred in pediatric deferasirox tablets for oral suspension-treated patients. Liver failure occurred in association with acute kidney injury in pediatric patients at risk for overchelation during a volume depleting event. Interrupt deferasirox tablets for oral suspension therapy when acute liver injury or acute kidney injury is suspected and during volume depletion. Monitor liver and renal function more frequently in pediatric patients who are receiving deferasirox tablets for oral suspension in the 20 to 40 mg/kg/day range and when iron burden is approaching normal. Use the minimum effective dose to achieve and maintain a low iron burden [see Dosage and Administration (2.5), Warnings and Precautions (5.6), Adverse Reactions (6.1)].


    Measure transaminases (AST and ALT) and bilirubin in all patients before the initiation of treatment, and every 2 weeks during the first month and at least monthly thereafter. Consider dose modifications or interruption of treatment for severe or persistent elevations.


    Avoid the use of deferasirox tablets for oral suspension in patients with severe (Child-Pugh C) hepatic impairment. Reduce the starting dose in patients with moderate (Child-Pugh B) hepatic impairment [see Dosage and Administration (2.4), Use in Specific Populations (8.7)]. Patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment may be at higher risk for hepatic toxicity.



    5.3 Gastrointestinal (GI) Ulceration, Hemorrhage, and Perforation

    GI hemorrhage, including deaths, has been reported in deferasirox tablets for oral suspension-treated patients, especially in elderly patients who had advanced hematologic malignancies and/or low platelet counts. Nonfatal upper GI irritation, ulceration and hemorrhage have been reported in patients, including children and adolescents, receiving deferasirox tablets for oral suspension [see Adverse Reactions (6.1)]. Monitor for signs and symptoms of GI ulceration and hemorrhage during deferasirox tablets for oral suspension therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. The risk of gastrointestinal hemorrhage may be increased when administering deferasirox tablets for oral suspension in combination with drugs that have ulcerogenic or hemorrhagic potential, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, oral bisphosphonates, or anticoagulants. There have been reports of ulcers complicated with gastrointestinal perforation (including fatal outcome) [see Adverse Reactions (6.2)].


    5.4 Bone Marrow Suppression

    Neutropenia, agranulocytosis, worsening anemia, and thrombocytopenia, including fatal events, have been reported in patients treated with deferasirox tablets for oral suspension. Preexisting hematologic disorders may increase this risk. Monitor blood counts in all patients. Interrupt treatment with deferasirox tablets for oral suspension in patients who develop cytopenias until the cause of the cytopenia has been determined. Deferasirox tablets for oral suspension are contraindicated in patients with platelet counts below 50 x 109/L.

    5.5 Age-Related Risk of Toxicity

    Elderly Patients

    Deferasirox tablets for oral suspension have been associated with serious and fatal adverse reactions in the postmarketing setting among adults, predominantly in elderly patients. Monitor elderly patients treated with deferasirox tablets for oral suspension more frequently for toxicity [see Use in Specific Populations (8.5)].


    Pediatric Patients

    Deferasirox tablets for oral suspension has been associated with serious and fatal adverse reactions in pediatric patients in the postmarketing setting. These events were frequently associated with volume depletion or with continued deferasirox tablets for oral suspension doses in the 20 to 40 mg/kg/day range when body iron burden was approaching or in the normal range. Interrupt deferasirox tablets for oral suspension in patients with volume depletion, and resume deferasirox tablets for oral suspension when renal function and fluid volume have normalized. Monitor liver and renal function more frequently during volume depletion and in patients receiving deferasirox tablets for oral suspension in the 20 to 40 mg/kg/day range when iron burden is approaching the normal range. Use the minimum effective dose to achieve and maintain a low iron burden [see Dosage and Administration (2.4), Warnings and Precautions (5.6), Use in Specific Populations (8.4)].


    5.6 Overchelation

    For patients with transfusional iron overload, measure serum ferritin monthly to assess for possible overchelation of iron. An analysis of pediatric patients treated with deferasirox tablets for oral suspension in pooled clinical trials (n=158) found a higher rate of renal adverse events among patients receiving doses greater than 25 mg/kg/day while their serum ferritin values were less than 1,000 mcg/L. Consider dose reduction or closer monitoring of renal and hepatic function, and serum ferritin levels during these periods. Use the minimum effective dose to maintain a low-iron burden [see Adverse Reaction (6.1), Use in Specific Populations (8.4)].

    If the serum ferritin falls below 1000 mcg/L at 2 consecutive visits, consider dose reduction, especially if the dose is greater than 25 mg/kg/day [see Adverse Reactions (6.1)]. If the serum ferritin falls below 500 mcg/L, interrupt therapy with deferasirox tablets for oral suspension and continue monthly monitoring. Evaluate the need for ongoing chelation for patients whose conditions do not require regular blood transfusions. Use the minimum effective dose to maintain iron burden in the target range. Continued administration of deferasirox tablets for oral suspension in the 20 to 40 mg/kg/day range when the body iron burden is approaching or within the normal range has resulted in life-threatening adverse events [see Dosage and Administration (2.1)].

    Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.


    5.7 Hypersensitivity

    Deferasirox tablets for oral suspension may cause serious hypersensitivity reactions (such as anaphylaxis and angioedema), with the onset of the reaction usually occurring within the first month of treatment [see Adverse Reactions (6.2)]. If reactions are severe, discontinue deferasirox tablets for oral suspension and institute appropriate medical intervention. Deferasirox tablets for oral suspension are contraindicated in patients with known hypersensitivity to deferasirox products and should not be reintroduced in patients who have experienced previous hypersensitivity reactions on deferasirox products due to the risk of anaphylactic shock.


    5.8 Severe Skin Reactions

    Severe cutaneous adverse reactions (SCARs) including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), which could be life-threatening or fatal have been reported during deferasirox tablets for oral suspension therapy [see Adverse Reactions (6.1, 6.2)]. Cases of erythema multiforme have been observed. Advise patients of the signs and symptoms of severe skin reactions, and closely monitor. If any severe skin reactions are suspected, discontinue deferasirox tablets for oral suspension immediately and do not reintroduce deferasirox tablets for oral suspension therapy.


    5.9 Skin Rash

    Rashes may occur during deferasirox tablets for oral suspension treatment [see Adverse Reactions (6.1)]. For rashes of mild to moderate severity, deferasirox tablets for oral suspension may be continued without dose adjustment, since the rash often resolves spontaneously. In severe cases, interrupt treatment with deferasirox tablets for oral suspension. Reintroduction at a lower dose with escalation may be considered after resolution of the rash.

    5.10 Auditory and Ocular Abnormalities

    Auditory disturbances (high frequency hearing loss, decreased hearing), and ocular disturbances (lens opacities, cataracts, elevations in intraocular pressure, and retinal disorders) were reported at a frequency of less than 1% with deferasirox tablets for oral suspension therapy in the clinical studies. The frequency of auditory adverse events irrespective of causality was increased among pediatric patients who received deferasirox tablets for oral suspension doses greater than 25 mg/kg/day when serum ferritin was less than 1,000 mcg/L [see Warnings and Precautions (5.6)].


    Perform auditory and ophthalmic testing (including slit-lamp examinations and dilated fundoscopy) before starting deferasirox tablets for oral suspension treatment and thereafter at regular intervals (every 12 months). If disturbances are noted, monitor more frequently. Consider dose reduction or interruption.

    6.1 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.

    Transfusional Iron Overload
    A total of 700 adult and pediatric patients were treated with deferasirox tablets for oral suspension (deferasirox) for 48 weeks in premarketing studies. These included 469 patients with beta-thalassemia, 99 with rare anemias, and 132 with sickle cell disease. Of these patients, 45% were male, 70% were Caucasian and 292 patients were  less than 16 years of age. In the sickle cell disease population, 89% of patients were black. Median treatment duration among the sickle cell patients was 51 weeks. Of the 700 patients treated, 469 (403 beta-thalassemia and 66 rare anemias) were entered into extensions of the original clinical protocols. In ongoing extension studies, median durations of treatment were 88 to 205 weeks.

    Six hundred twenty-seven (627) patients with MDS were enrolled across 5 uncontrolled trials. These studies varied in duration from 1 to 5 years. The discontinuation rate across studies in the first year was 46% (AEs 20%, withdrawal of consent 10%, death 8%, other 4%, lab abnormalities 3%, and lack of efficacy 1%). Among 47 patients enrolled in the study of 5-year duration, 10 remained on deferasirox tablets for oral suspension at the completion of the study.

    Table 1 displays adverse reactions occurring in  greater than 5% of deferasirox tablets for oral suspension-treated beta-thalassemia patients (Study 1), sickle cell disease patients (Study 3), and patients with MDS (MDS pool). Abdominal pain, nausea, vomiting, diarrhea, skin rashes, and increases in serum creatinine were the most frequent adverse reactions reported with a suspected relationship to deferasirox tablets for oral suspension. Gastrointestinal symptoms, increases in serum creatinine, and skin rash were dose related.

    ***Includes ‘blood creatinine increased’ and ‘blood creatinine abnormal’, which were reported as adverse events. See also Table 2.

    In Study 1, a total of 113 (38%) patients treated with deferasirox tablets for oral suspension had increases in serum creatinine  greater than 33% above baseline on 2 separate occasions (Table 2) and 25 (8%) patients required dose reductions. Increases in serum creatinine appeared to be dose related [see Warnings and Precautions (5.1)]. In this study, 17 (6%) patients treated with deferasirox tablets for oral suspension developed elevations in SGPT/ALT levels  greater than 5 times the ULN  at 2 consecutive visits. Of these, 2 patients had liver biopsy proven drug-induced hepatitis and both discontinued deferasirox tablets for oral suspension therapy [see Warnings and Precautions (5.2)]. An additional 2 patients, who did not have elevations in SGPT/ALT  greater than 5 times the ULN, discontinued deferasirox tablets for oral suspension because of increased SGPT/ALT. Increases in transaminases did not appear to be dose related. Adverse reactions that led to discontinuations included abnormal liver function tests (2 patients) and drug-induced hepatitis (2 patients), skin rash, glycosuria/proteinuria, Henoch Schönlein purpura, hyperactivity/insomnia, drug fever, and cataract (1 patient each).

    In Study 3, a total of 48 (36%) patients treated with deferasirox tablets for oral suspension had increases in serum creatinine  greater than 33% above baseline on 2 separate occasions (Table 2) [see Warnings and Precautions (5.1)]. Of the patients who experienced creatinine increases in Study 3, 8 deferasirox tablets for oral suspension-treated patients required dose reductions. In this study, 5 patients in the deferasirox tablets for oral suspension group developed elevations in SGPT/ALT levels  greater than 5 times the ULN at 2 consecutive visits and 1 patient subsequently had deferasirox tablets for oral suspension permanently discontinued. Four additional patients discontinued deferasirox tablets for oral suspension due to adverse reactions with a suspected relationship to study drug, including diarrhea, pancreatitis associated with gallstones, atypical tuberculosis, and skin rash.

    In the MDS pool, in the first year, a total of 229 (37%) patients treated with deferasirox tablets for oral suspension had increases in serum creatinine  greater than 33% above baseline on 2 consecutive occasions (Table 2) and 8 (3.5%) patients permanently discontinued [see Warnings and Precautions (5.1)]. A total of 5 (0.8%) patients developed SGPT/ALT levels greater than 5 times the ULN at 2 consecutive visits. The most frequent adverse reactions that led to discontinuation included increases in serum creatinine, diarrhea, nausea, rash, and vomiting. Death was reported in the first year in 52 (8%) of patients [see Clinical Studies (14)].

    Proteinuria

    In clinical studies, urine protein was measured monthly. Intermittent proteinuria (urine protein/creatinine ratio  greater than 0.6 mg/mg) occurred in 18.6% of deferasirox tablets for oral suspension-treated patients compared to 7.2% of deferoxamine-treated patients in Study 1 [see Warnings and Precautions (5.1)].


    Other Adverse Reactions

    In the population of more than 5,000 patients with transfusional iron overload who have been treated with deferasirox tablets for oral suspension during clinical trials, adverse reactions occurring in 0.1% to 1% of patients included gastritis, edema, sleep disorder, pigmentation disorder, dizziness, anxiety, maculopathy, cholelithiasis, pyrexia, fatigue, laryngeal pain, cataract, hearing loss, gastrointestinal hemorrhage, gastric ulcer (including multiple ulcers), duodenal ulcer, renal tubular disorder (Fanconi Syndrome), and acute pancreatitis (with and without underlying biliary conditions). Adverse reactions occurring in 0.01% to 0.1% of patients included optic neuritis, esophagitis, erythema multiforme, and drug reaction with eosinophilia and systemic symptoms (DRESS). Adverse reactions, which most frequently led to dose interruption or dose adjustment during clinical trials were rash, gastrointestinal disorders, infections, increased serum creatinine, and increased serum transaminases.


    Pooled Analysis of Pediatric Clinical Trial Data

    A nested case control analysis was conducted within a deferasirox pediatric pooled clinical trial dataset to evaluate the effects of dose and serum ferritin level, separately and combined, on kidney function. Among 1213 children (aged 2 to 15 years) with transfusion-dependent thalassemia, 162 cases of acute kidney injury (eGFR <90 mL/min/1.73 m2) and 621 matched-controls with normal kidney function (eGFR >120 mL/min/1.73 m2) were identified. The primary findings were:


    -        A 26% increased risk of acute kidney injury was observed with each 5 mg/kg increase in daily deferasirox tablets for oral suspension dosage starting at 20 mg/kg/day (95% CI: 1.08 to 1.48).

    -        A 25% increased risk for acute kidney injury was observed with each 250 mcg/L decrease in serum ferritin starting at 1250 mcg/L (95% CI: 1.01 to 1.56).

    -        Among pediatric patients with a serum ferritin <1000 mcg/L, those who received deferasirox tablets for oral suspension dosage >30 mg/kg/day, compared to those who received lower dosages, had a higher risk for acute kidney injury (OR=4.47, 95% CI: 1.25 to 15.95), consistent with overchelation.


    In addition, a cohort based analysis of adverse events was conducted in the deferasirox pediatric pooled clinical trial data. Pediatric patients who received deferasirox tablets for oral suspension dose >25 mg/kg/day when their serum ferritin was <1000 mcg/L (n=158) had a 6-fold greater rate of renal adverse events (IRR = 6, 95% CI: 1.75 to 21.36) and a 2-fold greater rate of dose interruptions (IRR= 2.06, 95% CI: 1.33 to 3.17) compared to the time-period prior to meeting these simultaneous criteria. Adverse events of special interest (cytopenia, renal, hearing, and gastrointestinal disorders) occurred 1.9-fold more frequently when these simultaneous criteria were met, compared to preceding time-periods (IRR=1.91, 95% CI: 1.05 to 3.48) [see Warnings and Precautions (5.6)].


    Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.


    6.2 Postmarketing Experience

    The following adverse reactions have been spontaneously reported during postapproval use of deferasirox tablets for oral suspension in the transfusional-iron overload setting. Because these reactions are reported voluntarily from a population of uncertain size, in which patients may have received concomitant medication, it is not always possible to reliably estimate frequency or establish a causal relationship to drug exposure.

    Skin and Subcutaneous Tissue Disorders: Stevens-Johnson syndrome (SJS), hypersensitivity vasculitis, urticaria, alopecia, toxic epidermal necrolysis (TEN)


    Immune System Disorders: hypersensitivity reactions (including anaphylactic reaction and angioedema)


    Renal and Urinary Disorders: acute renal failure, tubulointerstitial nephritis


    Hepatobiliary Disorders: hepatic failure


    Gastrointestinal Disorders: gastrointestinal perforation


    Blood and Lymphatic System Disorders: worsening anemia

    5-Year Pediatric Registry

    In a 5-year observational study, 267 pediatric patients 2 to <6 years of age (at enrollment) with transfusional hemosiderosis received deferasirox. Of the 242 patients who had pre-and post-baseline eGFR measurements, 116 (48%) patients had a decrease in eGFR of ≥33% observed at least once. Twenty-one (18%) of these 116 patients with decreased eGFR had a dose interruption, and 15 (13%) of these 116 patients had a dose decrease within 30 days. Adverse events leading to permanent discontinuation from the study included liver injury (n=11), renal tubular disorder (n=1), proteinuria (n=1), hematuria (n=1), upper gastrointestinal hemorrhage (n=1), vomiting (n=2), abdominal pain (n=1), and hypokalemia (n=1).


  • 7 DRUG INTERACTIONS

    7.1 Aluminum-Containing Antacid Preparations

    The concomitant administration of deferasirox tablets for oral suspension and aluminum-containing antacid preparations has not been formally studied. Although deferasirox has a lower affinity for aluminum than for iron, do not take deferasirox tablets for oral suspension with aluminum-containing antacid preparations due to the mechanism of action of deferasirox tablets for oral suspension.

    7.2 Agents Metabolized by CYP3A4

    Deferasirox may induce CYP3A4 resulting in a decrease in CYP3A4 substrate concentration when these drugs are coadministered. Closely monitor patients for signs of reduced effectiveness when deferasirox is administered with drugs metabolized by CYP3A4 (e.g., alfentanil, aprepitant, budesonide, buspirone, conivaptan, cyclosporine, darifenacin, darunavir, dasatinib, dihydroergotamine, dronedarone, eletriptan, eplerenone, ergotamine, everolimus, felodipine, fentanyl, hormonal contraceptive agents, indinavir, fluticasone, lopinavir, lovastatin, lurasidone, maraviroc, midazolam, nisoldipine, pimozide, quetiapine, quinidine, saquinavir, sildenafil, simvastatin, sirolimus, tacrolimus, tolvaptan, tipranavir, triazolam, ticagrelor, and vardenafil) [see Clinical Pharmacology (12.3)].

    7.3 Agents Metabolized by CYP2C8

    Deferasirox inhibits CYP2C8 resulting in an increase in CYP2C8 substrate (e.g., repaglinide and paclitaxel) concentration when these drugs are coadministered. If deferasirox tablets for oral suspension and repaglinide are used concomitantly, consider decreasing the dose of repaglinide and perform careful monitoring of blood glucose levels. Closely monitor patients for signs of exposure related toxicity when deferasirox tablets for oral suspension are coadministered with other CYP2C8 substrates [see Clinical Pharmacology (12.3)].

    7.4 Agents Metabolized by CYP1A2

    Deferasirox inhibits CYP1A2 resulting in an increase in CYP1A2 substrate (e.g., alosetron, caffeine, duloxetine, melatonin, ramelteon, tacrine, theophylline, tizanidine) concentration when these drugs are coadministered. An increase in theophylline plasma concentrations could lead to clinically significant theophylline-induced CNS or other adverse reactions. Avoid the concomitant use of theophylline or other CYP1A2 substrates with a narrow therapeutic index (e.g., tizanidine) with deferasirox tablets for oral suspension. Monitor theophylline concentrations and consider theophylline dose modification if you must coadminister theophylline with deferasirox tablets for oral suspension. Closely monitor patients for signs of exposure related toxicity when deferasirox tablets for oral suspension are coadministered with other drugs metabolized by CYP1A2 [see Clinical Pharmacology (12.3)].

    7.5 Agents Inducing UDP-glucuronosyltransferase (UGT) Metabolism

    Deferasirox is a substrate of UGT1A1 and to a lesser extent UGT1A3. The concomitant use of deferasirox tablets for oral suspension with potent UGT inducers (e.g., rifampicin, phenytoin, phenobarbital, ritonavir) may result in a decrease in deferasirox tablets for oral suspension efficacy due to a possible decrease in deferasirox concentration. Avoid the concomitant use of potent UGT inducers with deferasirox tablets for oral suspension. Consider increasing the initial dose of deferasirox tablets for oral suspension if you must coadminister these agents together [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].

    7.6 Bile Acid Sequestrants

    Avoid the concomitant use of bile acid sequestrants (e.g., cholestyramine, colesevelam, colestipol) with deferasirox tablets for oral suspension due to a possible decrease in deferasirox concentration. If you must coadminister these agents together, consider increasing the initial dose of deferasirox tablets for oral suspension [see Dosage and Administration (2.5), Clinical Pharmacology (12.3)].

    7.7 Busulfan

    Increased exposure of busulfan was observed with concomitant use with deferasirox. Monitor plasma concentrations of busulfan when coadministered with deferasirox to allow dose adjustment of busulfan as needed [see Clinical Pharmacology (12.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are no studies with deferasirox tablets for oral suspension in pregnant women to inform drug-associated risks.


    Administration of deferasirox to rats during pregnancy resulted in decreased offspring viability and an increase in renal anomalies in male offspring at doses that were about or less than the recommended human dose on an mg/m2 basis. No fetal effects were noted in pregnant rabbits at doses equivalent to the human recommended dose on an mg/m2 basis. Deferasirox tablets for oral suspension should be used during pregnancy only if the potential benefit justifies the potential risk to the 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. However, the background risk in the U.S. general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.


    Data

    Animal Data

    In embryo-fetal developmental studies, pregnant rats and rabbits received oral deferasirox during the period of organogenesis at doses up to 100 mg/kg/day in rats and 50 mg/kg/day in rabbits (1.2 times the maximum recommended human dose (MRHD) on an mg/m2 basis). These doses resulted in maternal toxicity but no fetal harm was observed.


    In a prenatal and postnatal developmental study, pregnant rats received oral deferasirox daily from organogenesis through lactation day 20 at doses of 10, 30, and 90 mg/kg/day (0.1, 0.3, and 1 times the MRHD on an mg/m2 basis). Maternal toxicity, loss of litters, and decreased offspring viability occurred at 90 mg/kg/day (1 times the MRHD on a mg/m2 basis) and increases in renal anomalies in male offspring occurred at 30 mg/kg/day (0.3 times the MRHD on a mg/m2 basis).

    8.2 Lactation

    Risk Summary

    No data are available regarding the presence of deferasirox or its metabolites in human milk, the effects of the drug on the breastfed child, or the effects of the drug on milk production. Deferasirox and its metabolites were excreted in rat milk. Because many drugs are excreted in human milk, and because of the potential for serious adverse reactions in a breastfeeding child from deferasirox and its metabolites, a decision should be made whether to discontinue breastfeeding or to discontinue the drug, taking into account the importance of the drug to the mother.



    8.3 Females and Males of Reproductive Potential

    Contraception

    Counsel patients to use non-hormonal method(s) of contraception since deferasirox tablets for oral suspension can render hormonal contraceptives ineffective [see Drug Interactions (7.2)].

    8.4 Pediatric Use

    Transfusional Iron Overload

    The safety and effectiveness of deferasirox tablets for oral suspension have been established in pediatric patients 2 years of age and older for the treatment of transfusional iron overload [see Dosage and Administration (2.1)].


    Safety and effectiveness have not been established in pediatric patients less than 2 years of age for the treatment of transfusional iron overload.


    Pediatric approval for treatment of transfusional iron overload was based on clinical studies of 292 pediatric patients 2 years to less than 16 years of age with various congenital and acquired anemias. Seventy percent of these patients had beta-thalassemia [see Indications and Usage (1), Dosage and Administration (2.1), Clinical Studies (14)]. In those clinical studies, 173 children (ages 2 to < 12 years) and 119 adolescents (ages 12 to < 17 years) were exposed to deferasirox.


    In general, risk factors for deferasirox-associated kidney injury include preexisting renal disease, volume depletion, overchelation, and concomitant use of other nephrotoxic drugs. Acute kidney injury, and acute liver injury and failure has occurred in pediatric patients. In a pooled safety analysis, pediatric patients with higher deferasirox tablets for oral suspension exposures had a greater probability of renal toxicity and decreased renal function, resulting in increased deferasirox exposure and progressive renal toxicity/kidney injury. Higher rates of renal adverse events have been identified among pediatric patients receiving deferasirox tablets for oral suspension doses greater than 25 mg/kg/day when their serum ferritin values were less than 1,000 mcg/L [see Dosage and Administration (2.5), Warnings and Precautions (5.1, 5.6), Adverse Reactions (6.1, 6.2)].


    Monitor renal function by estimating GFR using an eGFR prediction equation appropriate for pediatric patients and evaluate renal tubular function. Monitor renal function more frequently in pediatric patients in the presence of renal toxicity risk factors, including episodes of dehydration, fever and acute illness that may result in volume depletion or decreased renal perfusion. Use the minimum effective dose [see  Warnings and Precautions (5.1)].


    Interrupt deferasirox tablets for oral suspension in pediatric patients with transfusional iron overload for acute illnesses, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake, and monitor more frequently. Resume therapy as appropriate, based on assessments of renal function, when oral intake and volume status are normal. Evaluate the risk benefit profile of continued deferasirox tablets for oral suspension use in the setting of decreased renal function. Avoid use of other nephrotoxic drugs [see Dosage and Administration (2.5), Warnings and Precautions (5.1)].

    Juvenile Animal Toxicity Data

    Renal toxicity was observed in adult mice, rats, and marmoset monkeys administered deferasirox at therapeutic doses. In a neonatal and juvenile toxicity study in rats, deferasirox was administered orally from postpartum Day 7 through 70, which equates to a human age range of term neonate through adolescence. Increased renal toxicity was identified in juvenile rats compared to adult rats at a dose based on mg/m2 approximately 0.4 times the recommended dose of 20 mg/kg/day. A higher frequency of renal abnormalities was noted when deferasirox was administered to non-iron overloaded animals compared to iron overloaded animals.

    Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation’s EXJADE® (deferasirox) tablets for oral suspension. However, due to Novartis Pharmaceuticals Corporation’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    8.5 Geriatric Use

    Four hundred thirty-one (431) patients  greater than or equal to 65 years of age were studied in clinical trials of deferasirox tablets for oral suspension in the transfusional iron overload setting. The majority of these patients had myelodysplastic syndrome (MDS) (n=393). In these trials, elderly patients experienced a higher frequency of adverse reactions than younger patients. Monitor elderly patients for early signs or symptoms of adverse reactions that may require a dose adjustment. Elderly patients are at increased risk for toxicity due to the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range.

    In elderly patients, including those with MDS, individualize the decision to remove accumulated iron based on clinical circumstances and the anticipated clinical benefit and risks of deferasirox tablets for oral suspension therapy.

    8.6 Renal Impairment

    Deferasirox tablets for oral suspension is contraindicated in patients with eGFR less than 40 mL/min/1.73 m2 [see Contraindications (4)]. For patients with renal impairment (eGFR 40 to 60 mL/min/1.73 m2), reduce the starting dose by 50% [see Dosage and Administration (2.4)]. Exercise caution in pediatric patients with eGFR between 40 and 60 mL/minute/1.73 m2 [see Dosage and Administration (2.4)]. If treatment is needed, use the minimum effective dose with enhanced monitoring of glomerular and renal tubular function. Individualize dose titration based on improvement in renal injury [see Dosage and Administration (2.4, 2.5)].

    Deferasirox tablets for oral suspension can cause glomerular dysfunction, renal tubular toxicity, or both, and can result in acute renal failure. Monitor all patients closely for changes in eGFR and renal tubular dysfunction during deferasirox tablets for oral suspension treatment. If either develops, consider dose reduction, interruption or discontinuation of deferasirox tablets for oral suspension until glomerular or renal tubular function returns to baseline [see Dosage and Administration (2.4, 2.5), Warnings and Precautions (5.1)].




    8.7 Hepatic Impairment

    Avoid the use of deferasirox tablets for oral suspension in patients with severe (Child-Pugh C) hepatic impairment. For patients with moderate (Child-Pugh B) hepatic impairment, the starting dose should be reduced by 50%. Closely monitor patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment for efficacy and adverse reactions that may require dose titration [see Dosage and Administration (2.4), Warnings and Precautions (5.2)].

  • 10 OVERDOSAGE

    Cases of overdose (2 to 3 times the prescribed dose for several weeks) have been reported. In one case, this resulted in hepatitis, which resolved without long-term consequences after a dose interruption. In one pediatric case, a dose of 2 to 3 times the prescribed dose for 6 days, resulted in acute renal failure requiring hemofiltration and acute liver injury/failure, which were reversible with intensive care support. Single doses up to 80 mg per kg per day in iron overloaded beta-thalassemic patients have been tolerated with nausea and diarrhea noted. In healthy volunteers, single doses of up to 40 mg per kg per day were tolerated. There is no specific antidote for deferasirox tablets for oral suspension.  In case of overdose, induce vomiting and employ gastric lavage.


  • 11 DESCRIPTION

    Deferasirox is an iron chelating agent. Deferasirox tablets for oral suspension contain 125 mg, 250 mg, or 500 mg deferasirox. Deferasirox is designated chemically as 4-[3,5-Bis (2-hydroxyphenyl)-1H-1,2,4-triazol-1-yl]-benzoic acid and its structural formula is:

    Structure

    Deferasirox is a white to slightly yellow powder. Its molecular formula is C21H15N3O4 and its molecular weight is 373.36 g/mol.


    Inactive Ingredients: Crospovidone (NF), sodium starch glycolate (NF), croscarmellose sodium (NF), colloidal silicon dioxide (NF), sodium lauryl sulphate (NF), povidone (K-30) (USP), lactose monohydrate (NF), and magnesium stearate (NF).

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Deferasirox tablets for oral suspension are an orally active chelator that is selective for iron (as Fe3+). It is a tridentate ligand that binds iron with high affinity in a 2:1 ratio. Although deferasirox has very low affinity for zinc and copper there are variable decreases in the serum concentration of these trace metals after the administration of deferasirox. The clinical significance of these decreases is uncertain.

    12.2 Pharmacodynamics

    Pharmacodynamic effects tested in an iron balance metabolic study showed that deferasirox (10, 20, and 40 mg per kg per day) was able to induce a mean net iron excretion (0.119, 0.329, and 0.445 mg Fe/kg body weight per day, respectively) within the clinically relevant range (0.1 to 0.5 mg per kg per day). Iron excretion was predominantly fecal.

    An analysis of pooled pediatric clinical trial data found a statistically significant relationship between exposure and the probability of renal toxicity (increase in serum creatinine and urinary protein), resulting in a decrease in renal function. Decreases in renal function resulted in an increase in deferasirox exposure, which may increase the probability of renal toxicity.

    Cardiac Electrophysiology

    At the maximum approved recommended dose, deferasirox does not prolong the QT interval to any clinically relevant extent.


    12.3 Pharmacokinetics

    Absorption

    Deferasirox tablets for oral suspension are absorbed following oral administration with median times to maximum plasma concentration (Tmax) of about 1.5 to 4 hours. The Cmax and AUC of deferasirox increase approximately linearly with dose after both single administration and under steady-state conditions. Exposure to deferasirox increased by an accumulation factor of 1.3 to 2.3 after multiple doses. The absolute bioavailability (AUC) of deferasirox tablets for oral suspension is 70% compared to an intravenous dose. The bioavailability (AUC) of deferasirox was variably increased when taken with a meal.


    Distribution

    Deferasirox is highly (~99%) protein bound almost exclusively to serum albumin. The percentage of deferasirox confined to the blood cells was 5% in humans. The volume of distribution at steady state (Vss) of deferasirox is 14.37 ± 2.69 L in adults.


    Metabolism

    Glucuronidation is the main metabolic pathway for deferasirox, with subsequent biliary excretion. Deconjugation of glucuronidates in the intestine and subsequent reabsorption (enterohepatic recycling) is likely to occur. Deferasirox is mainly glucuronidated by UGT1A1 and to a lesser extent UGT1A3. CYP450-catalyzed (oxidative) metabolism of deferasirox appears to be minor in humans (about 8%). Deconjugation of glucuronide metabolites in the intestine and subsequent reabsorption (enterohepatic recycling) was confirmed in a healthy volunteer study in which the administration of cholestyramine 12 g twice daily (strongly binds to deferasirox and its conjugates) 4 and 10 hours after a single dose of deferasirox resulted in a 45% decrease in deferasirox exposure (AUC) by interfering with the enterohepatic recycling of deferasirox.


    Excretion

    Deferasirox and metabolites are primarily (84% of the dose) excreted in the feces. Renal excretion of deferasirox and metabolites is minimal (8% of the administered dose). The mean elimination half-life (t1/2) ranged from 8 to 16 hours following oral administration.


    Drug Interactions


    Midazolam: In healthy volunteers, the concomitant administration of deferasirox tablets for oral suspension and midazolam (a CYP3A4 probe substrate) resulted in a decrease of midazolam peak concentration by 23% and exposure by 17%. In the clinical setting, this effect may be more pronounced. The study was not adequately designed to conclusively assess the potential induction of CYP3A4 by deferasirox [see Drug Interactions (7.2)].


    Repaglinide: In a healthy volunteer study, the concomitant administration of deferasirox tablets for oral suspension (30 mg per kg/day for 4 days) and the CYP2C8 probe substrate repaglinide (single dose of 0.5 mg) resulted in an increase in repaglinide systemic exposure (AUC) to 2.3-fold of control and an increase in Cmax of 62% [see Drug Interactions (7.3)].


    Theophylline: In a healthy volunteer study, the concomitant administration of deferasirox tablets for oral suspension (repeated dose of 30 mg per kg/day) and the CYP1A2 substrate theophylline (single dose of 120 mg) resulted in an approximate doubling of the theophylline AUC and elimination half-life. The single dose Cmax was not affected, but an increase in theophylline Cmax is expected to occur with chronic dosing [see Drug Interactions (7.4)].

    Rifampicin: In a healthy volunteer study, the concomitant administration of deferasirox tablets for oral suspension (single dose of 30 mg per kg) and the potent UDP-glucuronosyltransferase (UGT) inducer rifampicin (600 mg/day for 9 days) resulted in a decrease of deferasirox systemic exposure (AUC) by 44% [see Drug Interactions (7.5)].


    Cholestyramine: The concomitant use of deferasirox tablets for oral suspension with bile acid sequestrants may result in a decrease in deferasirox tablets for oral suspension efficacy. In healthy volunteers, the administration of cholestyramine after a single dose of deferasirox resulted in a 45% decrease in deferasirox exposure (AUC) [see Drug Interactions (7.6)].

     Busulfan: Concomitant administration of deferasirox and busulfan resulted in an increase of busulfan exposure (AUC).

    In vitro Studies:

    • Cytochrome P450 Enzymes: Deferasirox inhibits human CYP3A4, CYP2C8, CYP1A2, CYP2A6, CYP2D6, and CYP2C19 in vitro.
    • Transporter Systems: The addition of cyclosporin A (PgP/MRP1/MRP2 inhibitor) or verapamil (PgP/MRP1 inhibitor) did not influence ICL670 permeability in vitro.

    Pharmacokinetics in Specific Populations


    Pediatric: Following oral administration of single or multiple doses, systemic exposure of adolescents and children to deferasirox was less than in adult patients. In children  less than 6 years of age, systemic exposure was about 50% lower than in adults.


    Geriatric: The pharmacokinetics of deferasirox have not been studied in elderly patients (65 years of age or older).


    Gender: Females have a moderately lower apparent clearance (by 17.5%) for deferasirox compared to males.


    Renal Impairment: Compared to patients with MDS and eGFR greater than 60 mL/min/1.73 m2, patients with MDS and eGFR 40 to 60 mL/min/1.73 m2 (n=34) had approximately 50% higher mean deferasirox trough plasma concentrations.


    Hepatic Impairment: In a single dose (20 mg/kg) study in patients with varying degrees of hepatic impairment, deferasirox exposure was increased compared to patients with normal hepatic function. The average total (free and bound) AUC of deferasirox increased 16% in 6 patients with mild (Child-Pugh A) hepatic impairment, and 76% in 6 patients with moderate (Child-Pugh B) hepatic impairment compared to 6 patients with normal hepatic function. The impact of severe (Child-Pugh C) hepatic impairment was assessed in only 1 patient.


  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    A 104-week oral carcinogenicity study in Wistar rats showed no evidence of carcinogenicity from deferasirox at doses up to 60 mg per kg per day (0.48 times the MRHD on an mg/m2 basis). A 26-week oral carcinogenicity study in p53 (+/-) transgenic mice has shown no evidence of carcinogenicity from deferasirox at doses up to 200 mg per kg per day (0.81 times the MRHD on a mg/m2  basis) in males and 300 mg per kg per day (1.21 times the MRHD on a mg/m2  basis) in females.


    Deferasirox was negative in the Ames test and chromosome aberration test with human peripheral blood lymphocytes. It was positive in 1 of 3 in vivo oral rat micronucleus tests.


    Deferasirox at oral doses up to 75 mg per kg per day (0.6 times the MRHD on a mg/m2 basis) was found to have no adverse effect on fertility and reproductive performance of male and female rats.

  • 14 CLINICAL STUDIES

    Transfusional Iron Overload
    The primary efficacy study, Study 1(NCT00061750),  was a multicenter, open-label, randomized, active-comparator control study to compare deferasirox and deferoxamine in patients with beta-thalassemia and transfusional hemosiderosis. Patients greater than or equal to 2 years of age were randomized in a 1:1 ratio to receive either oral deferasirox at starting doses of 5, 10, 20, or 30 mg per kg once daily or subcutaneous deferoxamine at starting doses of 20 to 60 mg per kg for at least 5 days per week based on LIC at baseline (2 to 3, greater than 3 to 7, greater than 7 to 14, and greater than 14 mg Fe/g dry weight). Patients randomized to deferoxamine who had LIC values less than 7 mg Fe/g dry weight were permitted to continue on their prior deferoxamine dose, even though the dose may have been higher than specified in the protocol.


    Patients were to have a liver biopsy at baseline and end of study (after 12 months) for LIC. The primary efficacy endpoint was defined as a reduction in LIC of greater than or equal to 3 mg Fe/g dry weight for baseline values greater than or equal to 10 mg Fe/g dry weight, reduction of baseline values between 7 and less than 10 to less than 7 mg Fe/g dry weight, or maintenance or reduction for baseline values less than 7 mg Fe/g dry weight.

    A total of 586 patients were randomized and treated, 296 with deferasirox and 290 with deferoxamine. The mean age was 17.1 years (range, 2 to 53 years); 52% were females and 88% were Caucasian. The primary efficacy population consisted of 553 patients (deferasirox n=276; deferoxamine n=277) who had LIC evaluated at baseline and 12 months or discontinued due to an adverse event. The percentage of patients achieving the primary endpoint was 52.9% for deferasirox and 66.4% for deferoxamine. The relative efficacy of deferasirox to deferoxamine cannot be determined from this study.

    In patients who had an LIC at baseline and at end of study, the mean change in LIC was -2.4 mg Fe/g dry weight in patients treated with deferasirox and -2.9 mg Fe/g dry weight in patients treated with deferoxamine.

    Reduction of LIC and serum ferritin was observed with deferasirox doses of 20 to 30 mg per kg per day. Deferasirox doses below 20 mg per kg per day failed to provide consistent lowering of LIC and serum ferritin levels (Figure 1). Therefore, a starting dose of 20 mg per kg per day is recommended [see Dosage and Administration (2.1)].

    Figure 1. Changes in Liver Iron Concentration and Serum Ferritin Following Deferasirox (5 to 30 mg per kg per day) in Study 1
    Figure 1
    Study 2 (NCT00061763) was an open-label, noncomparative trial of efficacy and safety of deferasirox given for 1 year to patients with chronic anemias and transfusional hemosiderosis. Similar to Study 1, patients received 5, 10, 20, or 30 mg per kg per day of deferasirox based on baseline LIC.

    A total of 184 patients were treated in this study: 85 patients with beta-thalassemia and 99 patients with other congenital or acquired anemias (myelodysplastic syndromes, n=47; Diamond-Blackfan syndrome, n=30; other, n=22). Nineteen percent  of patients were less than 16 years of age and 16% were  greater than 65 years of age. There was a reduction in the absolute LIC from baseline to end of study (-4.2 mg Fe/g dry weight).

    Study 3 (NCT00067080) was a multicenter, open-label, randomized trial of the safety and efficacy of deferasirox relative to deferoxamine given for 1 year in patients with sickle cell disease and transfusional hemosiderosis. Patients were randomized to deferasirox at doses of 5, 10, 20, or 30 mg per kg per day or subcutaneous deferoxamine at doses of 20 to 60 mg per kg per day for 5 days per week according to baseline LIC.

    A total of 195 patients were treated in this study: 132 with deferasirox and 63 with deferoxamine. Forty four percent (44%)  of patients were less than 16 years of age and 91% were black. At end of study, the mean change in LIC (as measured by magnetic susceptometry by a superconducting quantum interference device) in the per protocol-1 (PP-1) population, which consisted of patients who had at least 1 post-baseline LIC assessment, was -1.3 mg Fe/g dry weight for patients receiving deferasirox (n=113) and -0.7 mg Fe/g dry weight for patients receiving deferoxamine (n=54).

    One-hundred five (105) patients with thalassemia major and cardiac iron overload were enrolled in a study assessing the change in cardiac MRI T2* value (measured in milliseconds, ms) before and after treatment with deferasirox. Cardiac T2* values at baseline ranged from 5 to less than 20 ms. The geometric mean of cardiac T2* in the 68 patients who completed 3 years of deferasirox therapy increased from 11.98 ms at baseline to 17.12 ms at 3 years. Cardiac T2* values improved in patients with severe cardiac iron overload (less than 10 ms) and in those with mild to moderate cardiac iron overload (greater than or equal to 10 to less than 20 ms). The clinical significance of these observations is unknown.

    Six hundred twenty-seven (627) patients with MDS were enrolled across 5 uncontrolled trials. Two hundred thirty-nine (239) of the 627 patients were enrolled in trials that limited enrollment to patients with IPSS Low or Intermediate 1 risk MDS, and the remaining 388 patients were enrolled in trials that did not specify MDS risk stratification but required a life expectancy of greater than 1 year. Planned duration of treatment in these trials ranged from 1 year (365 patients) to 5 years (47 patients). These trials evaluated the effects of deferasirox therapy on parameters of iron overload, including LIC (125 patients) and serum ferritin (627 patients). The percent of patients completing planned duration of treatment was 51% in the largest 1-year study, 52% in the 3-year study and 22% in the 5-year study. The major causes for treatment discontinuation were withdrawal of consent, adverse reaction, and death. Over 1 year of follow-up across these pooled studies, mean change in serum ferritin was -332.8 (±2615.59) mcg/L (n=593) and mean change in LIC was -5.9 (±8.32) mg Fe/g dw (n=68). Results of these pooled studies in 627 patients with MDS suggest a progressive decrease in serum ferritin and LIC beyond 1 year in those patients who are able to continue deferasirox.

  • MEDICATION GUIDE

    Deferasirox (dee-FER-a-sir-ox)

    Tablets for Oral Suspension


    What is the most important information I should know about deferasirox tablets for oral suspension?

    Deferasirox tablets for oral suspension can cause serious side effects, including:

    Kidney problems. Deferasirox tablets for oral suspension can cause sudden (acute) kidney problems, including kidney failure that may require treatment with dialysis, and may cause death. Deaths have happened mostly in people who also have other health problems and had a blood disorder that was in an advanced stage. Adults and children who already have kidney problems and are taking certain medicines with deferasirox tablets for oral suspension may also have an increased risk of sudden kidney problems. Be sure to tell your healthcare provider about all the medicines you take during treatment with deferasirox tablets for oral suspension.


    Your healthcare provider should do blood and urine tests to check your or your child’s kidney function before and during treatment with deferasirox tablets for oral suspension. Call your or your child’s healthcare provider right away if:


    • your child becomes sick with fever, vomiting, or diarrhea and cannot drink fluids normally during treatment with deferasirox tablets for oral suspension. Your child may be dehydrated. Your child’s healthcare provider may need to temporarily stop treatment with deferasirox tablets for oral suspension and treat your child for dehydration to help prevent kidney problems. Your child’s healthcare provider may monitor your child’s kidney function more closely.
    • you notice that you or your child are passing less urine than usual during treatment with deferasirox tablets for oral suspension.

    Liver problems. Deferasirox tablets for oral suspension can cause liver problems, including liver failure that can sometimes cause death. Liver problems with deferasirox tablets for oral suspension may be more common in people who are over 55 years of age but can also happen in children. Liver failure has happened more often in people with cirrhosis of the liver and failure of other organs. Liver failure has also happened along with kidney problems in certain children who become dehydrated. See “Kidney problems” above.
    Your healthcare provider should do blood tests to check your liver function before you start and regularly during treatment with deferasirox tablets for oral suspension. Call your healthcare provider right away, if you develop any of the following signs and symptoms:

        drowsiness    yellowing or increased yellowing of your skin or eyes 
        upper right stomach-area (abdomen) pain    dark urine

    Bleeding, ulcers and tears of the stomach or intestine. Severe stomach and intestine bleeding (hemorrhage) that have caused death have happened in some people treated with deferasirox tablets for oral suspension, especially in elderly people who have advanced blood cancers or low platelet counts. Some people have also had ulcers of the stomach or intestine, sometimes with tears (perforation) that have caused death. In some people who have taken deferasirox tablets for oral suspension, including children and adolescents, irritation of the upper gastrointestinal tract, ulcers, and bleeding have happened, but did not cause death.

    Your risk of severe bleeding (hemorrhage) may be increased if you take deferasirox tablets for oral suspension along with other medicines that can cause ulcers or bleeding, such as:


       nonsteroidal anti-inflammatory drugs (NSAIDs)   certain osteoporosis medicines called oral bisphosphonates
       corticosteroids   blood thinner medicines


    Before you start taking deferasirox tablets for oral suspension, tell your healthcare provider if you are taking one of these medicines. Ask your healthcare provider if you are not sure. If you develop an ulcer of the stomach or intestine, or severe bleeding, your healthcare provider may stop deferasirox tablets for oral suspension.
    Elderly people may be at a higher risk of developing serious side effects and death due to serious side effects with deferasirox tablets for oral suspension. Your healthcare provider may need to monitor you more closely during treatment with deferasirox tablets for oral suspension.

    • Tell your healthcare provider if you get heartburn during treatment with deferasirox tablets for oral suspension.
    • Get emergency medical help right away if you vomit blood or pass black or bloody stools, or if you have severe stomach-area (abdomen) pain during treatment with deferasirox tablets for oral suspension.
