2 Dosageand Administration


  •  Transfusional Iron Overload: Initial dose for patients with estimated glomerular filtration rate (eGFR) greater than 60 mL/min/1.73 m2 is 14 mg per kg (calculated  to nearest whole tablet ) once daily. (2.1)
  • NTDT Syndromes: Initial dose for patients with eGFR greater than 60 mL/min/1.73 m2 is 7 mg per kg (calculated to nearest whole tablet once daily. (2.2)
  • See Full Prescribing information for information regarding monitoring, administration, and dose-reductions for organ impairment. (2.1,2.2, 2.3, 2.4)  

2.1 Transfusional Iron Overload


Deferasirox tablets 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 1,000 mcg/L. Prior to starting therapy, or increasing dose, evaluate: 

Initiating Therapy: The recommended initial dose of deferasirox tablets for patients 2 years of age and older with eGFR greater than 60 mL/min/1.73 m2 is 14 mg per kg body weight orally, once daily. Calculate doses (mg per kg per day) to the nearest whole tablet. Changes in weight of pediatric patients over time must be taken into account when calculating the dose. During Therapy:
  • Monitor serum ferritin monthly and adjust the dose of deferasirox tablets, 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 3.5 or 7 mg per kg and tailor adjustments to the individual patient’s response and therapeutic goals.
  • In patients not adequately controlled with doses of 21 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 28 mg per kg may be considered. Doses above 28 mg per kg are not recommended [ see Warnings and Precautions (5.6)].
  • Adjust dose based on serum ferritin levels 
    • If the serum ferritin falls below 1,000 mcg/L at 2 consecutive visits, consider dose reduction, especially if the deferasirox tablets dose is greater than 17.5 mg/kg/day [see Adverse Reactions (6.1)].
    • If the serum ferritin falls below 500 mcg/L, interrupt deferasirox tablets therapy and continue monthly monitoring.
    • Evaluate the need for ongoing chelation therapy for patients whose conditions no longer require regular blood transfusions.
    • 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 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)].

2.2 Iron Overload in Non-Transfusion-Dependent Thalassemia Syndromes


Deferasirox tablets therapy should only be considered when a patient with NTDT syndrome has an LIC of at least 5 mg Fe/g dw and a serum ferritin greater than 300 mcg/L.

Prior to starting therapy, obtain:

• LIC by liver biopsy or by an FDA-cleared or approved method for identifying patients for treatment with deferasirox therapy

• Serum ferritin level on at least 2 measurements 1-month apart [see Clinical Studies (14)]

• Baseline renal function:

o Obtain serum creatinine in duplicate (due to variations in measurements)

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 patients with eGFR greater than 60 mL/min/1.73 m2 is 7 mg per kg body weight orally once daily. Calculate doses (mg per kg per day) to the nearest whole tablet.

• If the baseline LIC is greater than 15 mg Fe/g dw, consider increasing the dose to 14 mg/kg/day after 4 weeks.

During Therapy:

• Monitor serum ferritin monthly. Interrupt treatment when serum ferritin is less than 300 mcg/L and obtain an LIC to determine whether the LIC has fallen to less than 3 mg Fe/g dw.

• Use the minimum effective dose to achieve a trend of decreasing ferritin.

• Monitor LIC every 6 months.

• After 6 months of therapy, if the LIC remains greater than 7 mg Fe/g dw, increase the dose of deferasirox to a maximum of 14 mg/kg/day. Do not exceed a maximum of 14 mg/kg/day.

• If after 6 months of therapy, the LIC is 3 to 7 mg Fe/g dw, continue treatment with deferasirox at no more than 7 mg/kg/day.

• When the LIC is less than 3 mg Fe/g dw, interrupt treatment with deferasirox and continue to monitor the LIC.

• Monitor blood counts, liver function, renal function and ferritin monthly [see Warnings and Precautions (5.1, 5.2, 5.4)].

• Increase monitoring frequency for pediatric patients who have acute illness, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake. Consider dose interruption until 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)].

Restart treatment when the LIC rises again to more than 5 mg Fe/g dw.

2.3 Administration


Swallow deferasirox tablets once daily with water or other liquids, preferably at the same time each day. Take deferasirox tablets on an empty stomach or with a light meal (contains less than 7% fat content and approximately 250 calories). Examples of light meals include 1 whole wheat English muffin, 1 packet jelly (0.5 ounces), and skim milk (8 fluid ounces) or a turkey sandwich (2 oz. turkey on whole wheat bread w/ lettuce, tomato, and 1 packet mustard). Do not take deferasirox tablets with aluminum-containing antacid products [see Drug Interactions (7.1)]. For patients who have difficulty swallowing whole tablets, deferasirox tablets may be crushed and mixed with soft foods (e.g., yogurt or applesauce) immediately prior to use and administered orally. Commercial crushers with serrated surfaces should be avoided for crushing a single 90 mg tablet. The dose should be immediately and completely consumed and not stored for future use.

For patients who are currently on chelation therapy with deferasirox tablets for oral suspension and converting to deferasirox tablets, the dose should be about 30% lower, rounded to the nearest whole tablet. The table below provides additional information on dosing conversion to deferasirox tablets.

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 [ see Warnings and Precautions (5.2), Use in Specific Populations (8.7)]. Patients with Baseline Renal Impairment Do not use deferasirox tablets 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 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) ].

2.5 Dose Modifications for Decrease in Renal Function While on Deferasirox Tablets


Deferasirox tablets 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  [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 7 mg per kg.

Pediatric Patients (ages 2 years to 17 years):
  • Reduce the dose by 7 mg per kg if eGFR decreases by greater than 33% below the average baseline measurement and repeat eGFR within 1 week
  •  Interrupt deferasirox tablets 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 use. Use the minimum effective deferasirox tablets 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 to prevent severe and irreversible renal injury [see Warnings and Precautions (5.1) ].

All Patients (regardless of age):

Non-Transfusion-Dependent Thalassemia Syndromes

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, interrupt therapy if the dose is 3.5 mg per kg, or reduce by 50% if the dose is 7 or 14 mg per kg.

Pediatric Patients (ages 10 years -17 years):

• Reduce the dose by 3.5 mg per kg if eGFR decreases by greater than 33% below the average baseline measurement and repeat the eGFR within 1 week.

• Increase monitoring frequency for pediatric patients who have acute illnesses, which can cause volume depletion, such as vomiting, diarrhea, or prolonged decreased oral intake. Consider dose interruption until 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 use. Use the minimum effective deferasirox tablets 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 to prevent severe and irreversible renal injury [see Warnings and Precautions (5.1)].

All Patients (regardless of age):

2.6 Dose Modifications Based on Concomitant Medications


UDP-glucuronosyltransferases (UGT) Inducers Concomitant use of UGT inducers decreases systemic exposure. Avoid the concomitant use of strong UGT inducers (e.g., rifampicin, phenytoin, phenobarbital, ritonavir) . If you must administer deferasirox tablets with a Strong UGT inducer, consider increasing the initial dose by 50%, and monitor serum ferritin levels and clinical responses for further dose modification [ see Dosage and Administration (2.1, 2.2), Drug Interactions (7.5)]. Bile Acid Sequestrants Concomitant use of bile acid sequestrants decreases systemic exposure. Avoid the concomitant use of bile acid sequestrants (e.g., cholestyramine, colesevelam, colestipol). If you must administer deferasirox tablets with a bile acid sequestrant, consider increasing the initial dose by 50%, and monitor serum ferritin levels and clinical responses for further dose modification [ see Dosage and Administration (2.1, 2.2), Drug Interactions (7.6)].

5 Warnings And Precautions


  • Acute Kidney Injury: Measure serum creatinine in duplicate before starting therapy. Monitor renal function during deferasirox therapy and reduce dose or interrupt therapy for toxicity. (2.1, 2.4, 5.1)
  • Hepatic Toxicity: Monitor hepatic function. Reduce dose or interrupt therapy for toxicity. (5.2)
  • Fatal and Nonfatal Gastrointestinal Bleeding, Ulceration, and Irritation: Risk may be greater in patients who are taking deferasirox in combination with drugs that have known ulcerogenic or hemorrhagic potential. (5.3)
  • Bone Marrow Suppression: Neutropenia, agranulocytosis, worsening anemia, and thrombocytopenia, including fatal events; monitor blood counts during deferasirox therapy. Interrupt therapy for toxicity. (5.4)
  • Age-related Risk of Toxicity: Monitor elderly and pediatric patients closely for toxicity. (5.5)
  • Hypersensitivity Reactions: Discontinue deferasirox for severe reactions and institute medical intervention. (5.7)
  • Severe Skin Reactions including Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN) and drug reaction with eosinophilia and systemic symptoms (DRESS): Discontinue deferasirox. (5.8)

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


Deferasirox is 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 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, adults and pediatric deferasirox-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 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, 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, 2.2)] . 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 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) ].

5.2Hepatic Toxicity and Failure


Deferasirox can cause hepatic injury, fatal in some patients. In Study 1, 4 patients (1.3%) discontinued deferasirox 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-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 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 in the 14 to 28 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 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.

5.3Gastrointestinal (GI) Ulceration, Hemorrhage, and Perforation


GI hemorrhage, including deaths, has been reported, 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 [ see Adverse Reactions (6.1)]. Monitor for signs and symptoms of GI ulceration and hemorrhage during deferasirox 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 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)].

5.4Bone Marrow Suppression


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

5.5 Age RelatedRisk of Toxicity


Elderly Patients Deferasirox has been associated with serious and fatal adverse reactions in the postmarketing setting among adults, predominantly in elderly patients. Monitor elderly patients treated with deferasirox more frequently for toxicity [see Use in Specific Populations (8.5)] . Pediatric Patients Deferasirox 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 equivalent to 14 to 28 mg/kg/day deferasirox when body iron burden was approaching or in the normal range. Interrupt deferasirox in patients with volume depletion, and resume deferasirox when renal function and fluid volume have normalized. Monitor liver and renal function more frequently during volume depletion and in patients receiving deferasirox in the 14 to 28 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 equivalent to 17.5 mg/kg/day deferasirox, 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 Reactions (6.1) , Use in Specific Populations (8.4)] . If the serum ferritin falls below 1,000 mcg/L at 2 consecutive visits, consider dose reduction, especially if the deferasirox dose is greater than 17.5 mg/kg/day [see Adverse Reactions (6.1)] . If the serum ferritin falls below 500 mcg/L, interrupt therapy with deferasirox 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 in the 14 to 28 mg/kg/day range, when the body iron burden is approaching or within the normal range can result in life threatening adverse reactions [see Dosage and Administration (2.1)] .

For patients with NTDT, measure LIC by liver biopsy or by using an FDA-cleared or approved method for monitoring patients receiving deferasirox therapy every 6 months on treatment. Interrupt deferasirox administration when the LIC is less than 3 mg Fe/g dw. Measure serum ferritin monthly, and if the serum ferritin falls below 300 mcg/L, interrupt deferasirox and obtain a confirmatory LIC [see Clinical Studies (14)].

5.7Hypersensitivity


Deferasirox 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 and institute appropriate medical intervention. Deferasirox is 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 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 immediately and do not reintroduce deferasirox therapy.

5.9 Skin Rash


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

5.10 Auditory and Ocular Abmormalities


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 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 equivalent to 17.5 mg/kg/day deferasirox 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 treatment and thereafter at regular intervals (every 12 months). If disturbances are noted, monitor more frequently. Consider dose reduction or interruption.

6 Adverse Reactions


The following clinically significant adverse reactions are also discussed in other sections of the labeling:


In patients with transfusional iron overload, the most frequently occurring (greater than 5%) adverse reactions are diarrhea, vomiting, nausea, abdominal pain, skin rashes, and increases in serum creatinine. In deferasirox-treated patients with NTDT syndromes, the most frequently occurring (greater than 5%) adverse reactions are diarrhea, rash and nausea.(6.1) To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy's Laboratories, Inc. at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical 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. Deferasirox was evaluated in healthy volunteer trials. Currently, there are no clinical data in patients with deferasirox tablets. Deferasirox contains the same active ingredient as deferasirox tablets for oral suspension. The following adverse reactions have been reported with deferasirox tablets for oral suspension. Transfusional Iron Overload A total of 700 adult and pediatric patients were treated with 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 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 at the completion of the study. Table 1 displays adverse reactions occurring in greater than 5% of deferasirox -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. Gastrointestinal symptoms, increases in serum creatinine, and skin rash were dose related.

a Adverse reaction frequencies are based on AEs reported regardless of relationship to study drug.

b Includes ‘abdominal pain’, ‘abdominal pain lower’, and ‘abdominal pain upper.’ 

C Includes ‘blood creatinine increased’ and ‘blood creatinine abnormal’. See also Table 2.

In Study 1, a total of 113 (38%) patients treated with deferasirox 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 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 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 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 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-treated patients required dose reductions. In this study, 5 patients in the deferasirox group developed elevations in SGPT/ALT levels greater than 5 times the ULN at 2 consecutive visits and 1 patient subsequently had deferasirox permanently discontinued.  Four additional patients discontinued 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 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)] .

Non-Transfusion-Dependent Thalassemia Syndromes

In Study 5, 110 patients with NTDT received 1 year of treatment with deferasirox 5 or 10 mg/kg/day and 56 patients received placebo in a double-blind, randomized trial. In Study 6, 130 of the patients who completed Study 5 were treated with open-label deferasirox at 5, 10, or 20 mg/kg/day (depending on the baseline LIC) for 1 year [see Clinical Studies (14)]. Table 3 and 4 display the frequency of adverse reactions in patients with NTDT. Adverse reactions with a suspected relationship to study drug were included in Table 3 if they occurred at ≥ 5% of patients in Study 5.

a The occurrence of nausea, and rash are included for Study 6. There were no additional adverse reactions with a suspected relationship to study drug occurring in >5% of patients in Study 6.

In Study 5, 1 patient in the placebo 10 mg/kg/day group experienced an ALT increase to greater than 5 times ULN and greater than 2 times baseline (Table 4). Three deferasirox-treated patients (all in the 10 mg/kg/day group) had 2 consecutive serum creatinine level increases greater than 33% from baseline and greater than ULN. Serum creatinine returned to normal in all 3 patients (in 1 spontaneously and in the other 2 after drug interruption). Two additional cases of ALT increase and 2 additional cases of serum creatinine increase were observed in the 1-year extension of Study 5. The number (%) of patients with NTDT with increase in serum creatinine or SGPT/ALT in Study 5 and Study 6 are presented in Table 4 below.

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-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  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 equivalent to 3.5 mg/kg deferasirox, starting at 20 mg/kg/day equivalent to 14 mg/kg/day deferasirox (95% CI: 1.08-1.48).
  • A 25% increased risk for acute kidney injury was observed with each 250 mcg/L decrease in serum ferritin starting at 1,250 mcg/L (95% CI: 1.01-1.56).
  • Among pediatric patients with a serum ferritin < 1,000 mcg/L, those who received deferasirox tablets for oral suspension dosage > 30 mg/kg/day, equivalent to 21 mg/kg/day deferasirox compared to those who received lower dosages, had a higher risk for acute kidney injury (OR = 4.47, 95% CI: 1.25-15.95), 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 equivalent to 17.5 mg/kg/day deferasirox when their serum ferritin was < 1,000 mcg/L (n = 158), had a 6-fold greater rate of renal adverse reactions (Incidence Rate Ratio IRR = 6.00, 95% CI: 1.75-21.36), and a 2-fold greater rate of dose interruptions (IRR = 2.06, 95% CI: 1.33-3.17) 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: 1.05-3.48) [see Warnings and Precautions (5.6)] .

Additional pediatric use information is approved for Novartis Pharmaceuticals Corporation's JADENU (desferasirox) tablets. However, due to Novartis Pharmaceuticals Corporation's marketing exclusivity rights, this drug product is not labeled with that information.

6.2 Postmarketing Experience


The following adverse reactions have been spontaneously reported during post-approval use of deferasirox 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), leukocytoclastic 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), vomiting (n = 2), renal tubular disorder (n = 1), proteinuria (n = 1), hematuria (n = 1), upper gastrointestinal hemorrhage (n = 1), abdominal pain (n = 1), and hypokalemia (n = 1).

7 Drug Interactions


  • Do not take deferasirox with aluminum-containing antacid preparations.(7.1)
  • Deferasirox increases the exposure of the repaglinide. Consider repaglinide dose reduction and monitor blood glucose levels. (7.3)
  • Avoid the use of deferasirox  with theophylline as theophylline levels could be increased. (7.4)
  • Deferasirox increases exposure of busulfan. Monitor plasma concentrations of busulfan when coadministered with deferasirox to allow dose adjustment of busulfan, as needed. (7.7)

7.1Aluminum-Containing Antacid Preparations


The concomitant administration of deferasirox 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 with aluminum-containing antacid preparations.

7.2Agents 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)].

7.3Agents 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 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 is coadministered with other CYP2C8 substrates [ see Clinical Pharmacology (12.3)].

7.4Agents 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. Monitor theophylline concentrations and consider theophylline dose modification if you must coadminister theophylline with deferasirox. Closely monitor patients for signs of exposure related toxicity when Deferasirox is coadministered with other drugs metabolized by CYP1A2 [ see Clinical Pharmacology (12.3)].

7.5Agents Inducing UDP-glucuronosyltransferase (UGT) Metabolism


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

7.6Bile Acid Sequestrants


Avoid the concomitant use of bile acid sequestrants (e.g., cholestyramine, colesevelam, colestipol) with deferasirox due to a possible decrease in deferasirox concentration. If you must coadminister these agents together, consider increasing the initial dose of deferasirox [ 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


  • Lactation: Advise women not to breastfeed. (8.2)

8.1 Pregnancy


Risk Summary There are no studies with the use of deferasirox 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 a 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 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 had 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 1.0 times the MRHD on a mg/m2 basis). Maternal toxicity, loss of litters, and decreased offspring viability occurred at 90 mg/kg/day (1.0 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 can render hormonal contraceptives ineffective [see Drug Interactions (7.2)].

8.4 Pediatric Use


Transfusional Iron Overload The safety and effectiveness of deferasirox 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.

Iron Overload in Non-Transfusion-Dependent Thalassemia Syndromes

The safety and effectiveness of deferasirox have been established in patients 10 years of age and older for the treatment of chronic iron overload with non-transfusion-dependent thalassemia (NTDT) syndromes [see Dosage and Administration (2.2)].

Safety and effectiveness have not been established in patients less than 10 years of age with chronic iron overload in NTDT syndromes.

Pediatric approval for treatment of NTDT syndromes with liver iron (Fe) concentration (LIC) of at least 5 mg Fe per gram of dry weight and a serum ferritin greater than 300 mcg/L was based on 16 pediatric patients treated with deferasirox therapy (10 years to less than 16 years of age) with chronic iron overload and NTDT. Use of deferasirox in these age groups is supported by evidence from adequate and well-controlled studies of deferasirox in adult and pediatric patients [see Indications and Usage (1.2), Dosage and Administration (2.2), Clinical Studies (14)].

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 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 equivalent to 17.5 mg/kg/day deferasirox 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 )].

Monitoring recommendations for all pediatric patients with Transfusional Iron Overload and NTDT

It is recommended that serum ferritin be monitored every month to assess the patient’s response to therapy and to minimize the risk of overchelation [see Warnings and Precautions (5.6)].

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 in pediatric patients with transfusional iron overload, and consider dose interruption in pediatric patients with non-transfusion-dependent 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 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)] .

JuveRenile 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 JADENU® (deferasirox) tablets. 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 patients greater than or equal to 65 years of age were studied in clinical trials of deferasirox in the transfusional iron overload setting. Two hundred twenty-five of these patients were between 65 and 75 years of age while 206 were greater than or equal to 75 years of age. 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.

8.6Renal Impairment


Deferasirox 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) , Clinical Pharmacology (12.3) ]. Exercise caution in pediatric patients with an 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 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 treatment. If either develops, consider dose reduction, interruption or discontinuation of deferasirox 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 use in patients with severe (Child-Pugh C) hepatic impairment. For patients with moderate (Child-Pugh B) hepatic impairment, reduce the starting dose 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), Clinical Pharmacology (12.3)].

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 of deferasirox up to 80 mg per kg per day with the tablet for oral suspension formulation in iron-overloaded beta-thalassemic patients have been tolerated with nausea and diarrhea noted. In healthy subjects, single doses of up to 40 mg per kg per day with the tablet for oral suspension formulation were tolerated.

Early signs of acute overdose are digestive effects such as abdominal pain, diarrhea, nausea, and vomiting. Hepatic and renal disorders have been reported, including cases of liver enzyme and creatinine increased with recovery after treatment discontinuation. An erroneously administered single dose of 90 mg/kg led to Fanconi syndrome which resolved after treatment.

There is no specific antidote for deferasirox. In case of overdose, it may be treated with induction of vomiting or gastric lavage, and by symptomatic treatment. 

11 Description


Deferasirox is an iron-chelating agent provided as a tablet for oral use. Deferasirox is designated chemically as 4-[3,5-bis(2-hydroxy-phenyl)-1H-1,2,4-triazol-1-yl] benzoic acid and has the following structural formula:

Deferasirox is a white to slightly yellow colour powder. It has a molecular formula C21H15N3O4 and molecular weight of 373.36.It is freely soluble in Dimethyl Formamide; sparingly soluble in Dimethylsulfoxide and practically insoluble in water.

Deferasirox tablets contain 90 mg, 180 mg, or 360 mg deferasirox. Inactive ingredients include colloidal silicon dioxide, croscarmellose sodium, hydrogenated castor oil, lactose monohydrate, low substituted hydroxy propyl cellulose, microcrystalline cellulose, poloxamer (188), povidone (K30) and sodium stearyl fumarate. The film coating contains .hypromellose, titanium dioxide, propylene glycol, talc and iron oxide yellow.

12 Clinical Pharmacology


12.1 Mechanism of Action


Deferasirox is 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 with the tablet for oral suspension formulation 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 Based on studies in patients with the tablet for oral suspension, deferasirox is absorbed following oral administration with median times to maximum plasma concentration (Tmax) of about 1.5 to 4 hours. In healthy subjects, deferasirox showed comparable Tmax. The maximal concentrations (Cmax) and area under the curve (AUC0-24h, AUCτ) 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 with the tablet for oral suspension formulation.

Tablets The absolute bioavailability [as measured by area under the curve over time to infinity (AUCinf)] of deferasirox tablets for oral suspension is 70% compared to an intravenous dose. The bioavailability (as measured by AUC inf) of deferasirox tablets was 36% greater than with deferasirox tablets for oral suspension. After strength- adjustment, the mean AUCinf of deferasirox tablets (i.e., 360 mg strength) was similar to that of deferasirox tablets for oral suspension (i.e., 500 mg strength) under fasting conditions; however the mean Cmax was increased by 30%. The 30% increase in Cmax observed with deferasirox tablets is not clinically meaningful.

The administration of deferasirox tablets with a light meal (approximately 250 calories with fat content less than 7% of total calories) indicated that the AUCinf and Cmax were similar to that under fasting conditions. The administration of deferasirox tablets with a high-fat meal (approximately 1000 calories with fat content greater than 50% of total calories), increased AUCinf by 18% and Cmax by 29% compared to that under fasting conditions [see Dosage and Administration (2.3)] .

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 subjects 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 (AUCinf) 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 dose). The mean elimination half-life (t1/2) ranged from 8 to 16 hours following oral administration.

Drug Interactions

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

Repaglinide: 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) increased repaglinide AUCinf to 2.3­ fold and Cmax of 1.6-fold [see Drug Interactions (7.3)].

Theophylline: 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 AUCinf  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: The concomitant administration of deferasirox tablets for oral suspension (single dose of 30 mg per kg) and the strong uridine diphosphate glucuronosyltransferase (UGT) inducer rifampicin (600 mg per day for 9 days)  decreased deferasirox AUCinf by 44% [ see Drug Interactions (7.5)].

Cholestyramine: The concomitant administration of cholestyramine after a single dose of deferasirox tablets for oral suspension decreased deferasirox AUCinf by 45% [ see Drug Interactions (7.6)].

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

In vitro studies:Deferasirox inhibited human CYP2A6, CYP2D6, and CYP2C19 in vitro. Deferasirox is not a substrate of P-glycoprotein, MRP1 or MRP2.

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.

Sex: The apparent clearance is 17.5% lower in females compared to males.

Renal Impairment: Compared to patients with MDS and eGFR greater than 60 mL/min/1.73m2, patients with MDS and eGFR 40 to 60 mL/min/1.73m2 (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) AUCinf 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/kg/day (0.7 times the MRHD on a 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/kg/day (1.2 times the MRHD on an mg/m2 basis) in males and 300 mg/kg/day (1.7 times the MRHD on an 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/kg/day (0.9 times the MRHD on an mg/m2 basis) was found to have no adverse effect on fertility and reproductive performance of male and female rats.

14 Clinical Studies


Deferasirox was evaluated in healthy subjects. There are no clinical data in patients with deferasirox. Deferasirox contains the same active ingredient as deferasirox tablets for oral suspension. The following information is based on clinical trials conducted with deferasirox tablets for oral suspension.

Transfusional Iron Overload The primary efficacy study, Study 1(NCT00061750), was a multicenter, open-label, randomized, active-comparator control study to compare deferasirox tablets for oral suspension 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 tablets for oral suspension 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 than14 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 to10 mg Fe/g dry weight, reduction of baseline values between 7 and less than10 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 tablets for oral suspension 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 tablets for oral suspension 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 tablets for oral suspension 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 tablets for oral suspension and -2.9 mg Fe/g dry weight in patients treated with deferoxamine.

Reduction of LIC and serum ferritin was observed with deferasirox tablet for oral suspension doses of 20 to 30 mg per kg per day. Deferasirox tablets for oral suspension 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 Tablets for Oral Suspension (5 to 30 mg per kg per day) in Study 1

Study 2 (NCT00061763) was an open-label, noncomparative trial of efficacy and safety of deferasirox tablets for oral suspension 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 tablets for oral suspension 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 or equal to 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 tablets for oral suspension relative to deferoxamine given for 1 year in patients with sickle cell disease and transfusional hemosiderosis. Patients were randomized to deferasirox tablets for oral suspension 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 tablets for oral suspension 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 tablets for oral suspension (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 tablets for oral suspension 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 than10 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 patients with MDS were enrolled across 5 uncontrolled trials. Two hundred thirty- nine 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 tablets for oral suspension 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 tablets for oral suspension.

Non-Transfusion-Dependent Thalassemia

Study 5(NCT00873041) was a randomized, double-blind, placebo-controlled trial of treatment with deferasirox tablets for oral suspension for patients 10 years of age or older with NTDT syndromes and iron overload. Eligible patients had an LIC of at least 5 mg Fe/g dw measured by R2 MRI and a serum ferritin exceeding 300 mcg/L at screening (2 consecutive values at least 14 days apart from each other). A total of 166 patients were randomized, 55 to the deferasirox tablets for oral suspension 5 mg/kg/day dose group, 55 to the deferasirox tablets for oral suspension 10 mg/kg/day dose group, and 56 to placebo (28 to each matching placebo group). Doses could be increased after 6 months if the LIC exceeded 7 mg Fe/g dw and the LIC reduction from baseline was less than 15%. The patients enrolled included 89 males and 77 females. The underlying disease was betathalassemia intermedia in 95 (57%) patients, HbE betathalassemia in 49 (30%) patients, and alpha-thalassemia in 22 (13%) patients. There were 17 pediatric patients in the study. Caucasians comprised 57% of the study population and Asians comprised 42%. The median baseline LIC (range) for all patients was 12.1 (2.6 to 49.1) mg Fe/g dw. Follow-up was for 1 year. The primary efficacy endpoint of change in LIC from baseline to Week 52 was statistically significant in favor of both deferasirox dose groups compared with placebo (p less than or equal to 0.001) (Table 5). Furthermore, a statistically significant dose effect of deferasirox was observed in favor of the 10 mg/kg/day dose group (10 versus 5 mg/kg/day, p = 0.009). In a descriptive analysis, the target LIC (less than 5 mg Fe/g dw) was reached by 15 (27%) of 55 patients in the 10 mg/kg/day arm, 8 (15%) of 55 patients in the 5 mg/kg/day arm and 2 (4%) of 56 patients in the combined placebo groups.

Study 6 (NCT00873041) was an open-label trial of deferasirox tablets for oral suspension for the treatment of patients previously enrolled on Study 5, including cross-over to active treatment for those previously treated with placebo. The starting dose of deferasirox tablets for oral suspension in Study 6 was assigned based on the patient’s LIC at completion of Study 5, being 20 mg/kg/day for an LIC exceeding 15 mg Fe/g dw, 10 mg/kg/day for LIC 3 to 15 mg Fe/g dw, and observation if the LIC was less than 3 mg Fe/g dw. Patients could continue on 5 mg/kg/day if they had previously exhibited at least a 30% reduction in LIC. Doses could be increased to a maximum of 20 mg/kg/day after 6 months if the LIC was more than 7 mg Fe/g dw and the LIC reduction from baseline was less than 15%. The primary efficacy endpoint in Study 6 was the proportion of patients achieving an LIC less than 5 mg Fe/g dw. A total of 133 patients were enrolled. Twenty patients began Study 6 with an LIC less than 5 mg Fe/g dw. Of the 113 patients with a baseline LIC of at least 5 mg Fe/g dw in Study 6, the target LIC (less than 5 mg Fe/g dw) was reached by 39 (35%). The responders included 4 (10%) of 39 patients treated at 20 mg/kg/day for a baseline LIC exceeding 15 mg Fe/g dw, and 31 (51%) of 61 patients treated at 10 mg/kg/day for a baseline LIC between 5 and 15 mg Fe/g dw. The absolute change in LIC at Week 52 by starting dose is shown in Table 5 below.

Medication Guide


Deferasirox (de fer a sir ox) tablets

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

Deferasirox tablets can cause serious side effects, including:

Kidney problems: Deferasirox tablets can cause 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 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. 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. Call your healthcare provider right away if: • your child becomes sick with fever, vomiting, or diarrhea and cannot drink fluids normally during treatment with deferasirox tablets. Your child may be dehydrated. Your healthcare provider may need to temporarily stop treatment with deferasirox tablets and treat your child for dehydration to help prevent kidney problems. Your 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.

Liver problems. Deferasirox tablets can cause liver problems, including liver failure that can sometimes cause death. Liver problems with deferasirox tablets 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.
