Boxed Warning

WARNING: RENAL FAILURE, HEPATIC FAILURE, and GASTROINTESTINAL HEMORRHAGE Renal Failure JADENU 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 JADENU dosing in all patients. JADENU is contraindicated in adult and pediatric patients with eGFR less than 40 mL/min/1.73 m 2 . 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 JADENU 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 JADENU 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 JADENU 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 JADENU for suspected GI ulceration or hemorrhage [see Warnings and Precautions (5.3)] . WARNING: RENAL FAILURE, HEPATIC FAILURE, and GASTROINTESTINAL H…

Dosage and administration

2 DOSAGE AND ADMINISTRATION Transfusional Iron Overload: Initial dose for patients with estimated glomerular filtration rate (eGFR) greater than 60 mL/min/1.73 m 2 is 14 mg per kg (calculated to nearest whole tablet or nearest whole sachet content for granules) once daily. ( 2.1 ) NTDT Syndromes: Initial dose for patients with eGFR greater than 60 mL/min/1.73 m 2 is 7 mg per kg (calculated to nearest whole tablet or nearest whole sachet content for granules) 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 JADENU 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: Serum ferritin level Baseline renal function: Obtain serum creatinine in duplicate (due to variations in measurements). 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). 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 JADENU for patients 2 years of age and older with eGFR greater than 60 mL/min/1.73 m 2 is 14 mg per kg body weight orally, once daily. Calculate doses (mg per kg per day) to the nearest whole tablet or nearest whole sachet content for granules. 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 JADENU, 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 JADENU dose is greater than 17.5 mg/kg/day [see Adverse Reactions (6.1)] . If the serum ferritin falls below 500 mcg/L, interrupt JADENU therapy to minimize the risk of overchelation, and continue monthly monitoring [see Warnings and Precautions (5.6)] . 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 JADENU 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 Popula…

Warnings

5 WARNINGS AND PRECAUTIONS Acute Kidney Injury: Measure serum creatinine in duplicate before starting therapy. Monitor renal function during JADENU 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 (GI) Bleeding, Ulceration, and Irritation: Risk may be greater in patients who are taking JADENU 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 JADENU 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 JADENU 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 JADENU. ( 5.8 ) 5.1 Acute Kidney Injury, Including Acute Renal Failure Requiring Dialysis and Renal Tubular Toxicity Including Fanconi Syndrome JADENU is contraindicated in patients with eGFR less than 40 mL/min/1.73 m 2 . Exercise caution in pediatric patients with eGFR between 40 and 60 mL/min/1.73 m 2 . 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 40-60 mL/min/1.73 m 2 ) reduce the starting dose by 50% [see Dosage and Administration (2.4, 2.5), Use in Specific Populations (8.6)] . JADENU 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 Exjade 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 Specific 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. Dose reduction or interruption may be considered if abnormalities occur in levels of markers of renal tubular function and/or as clinically indicated. Monitor serum ferritin monthly to evaluate for overc…

Drug interactions

7 DRUG INTERACTIONS Do not take JADENU with aluminum-containing antacid preparations. ( 7.1 ) Deferasirox increases the exposure of repaglinide. Consider repaglinide dose reduction and monitor blood glucose levels. ( 7.3 ) Avoid the use of JADENU 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 ) 7.1 Aluminum-Containing Antacid Preparations The concomitant administration of JADENU and aluminum-containing antacid preparations has not been formally studied. Although deferasirox has a lower affinity for aluminum than for iron, do not take JADENU with aluminum-containing antacid preparations. 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 JADENU 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 JADENU is 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 JADENU. Monitor theophylline concentrations and consider theophylline dose modification if you must coadminister theophylline with JADENU. Closely monitor patients for signs of exposure related toxicity when JADENU is 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 JADENU with strong UGT inducers (e.g., rifampicin, phenytoin, phenobarbital, ritonavir) may result in a decrease in JADENU efficacy due to a possible decrease in deferasirox concentration. Avoid the concomitant use of strong UGT inducers with JADENU. Consider increasing the initial dose of JADENU 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 JADENU due to a possible decrease in deferasirox concentration. If you must coadminister these agents together, consider increasing the initial dose of JADENU [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 o…

Pregnancy

8.1 Pregnancy Risk Summary There are no studies with the use of JADENU 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/m 2 basis. No fetal effects were noted in pregnant rabbits at doses equivalent to the human recommended dose on an mg/m 2 basis. JADENU 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/m 2 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/m 2 basis). Maternal toxicity, loss of litters, and decreased offspring viability occurred at 90 mg/kg/day (1.0 times the MRHD on a mg/m 2 basis), and increases in renal anomalies in male offspring occurred at 30 mg/kg/day (0.3 times the MRHD on a mg/m 2 basis).

Adverse reactions (label)

6 ADVERSE REACTIONS The following clinically significant adverse reactions are also discussed in other sections of the labeling: Acute Kidney Injury, Including Acute Renal Failure Requiring Dialysis, and Renal Tubular Toxicity Including Fanconi Syndrome [see Warnings and Precautions (5.1, 5.6)] Hepatic Toxicity and Failure [see Warnings and Precautions (5.2, 5.6)] GI Hemorrhage [see Warnings and Precautions (5.3)] Bone Marrow Suppression [see Warnings and Precautions (5.4)] Hypersensitivity [see Warnings and Precautions (5.7)] Severe Skin Reactions [see Warnings and Precautions (5.8)] Skin Rash [see Warnings and Precautions (5.9)] Auditory and Ocular Abnormalities [see Warnings and Precautions (5.10)] 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 Novartis Pharmaceuticals Corporation at 1-888-669-6682 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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. JADENU was evaluated in healthy volunteer trials. Currently, there are no clinical data in patients with JADENU tablets and JADENU Sprinkle granules. JADENU contains the same active ingredient as Exjade (deferasirox) tablets for oral suspension. The following adverse reactions have been reported with Exjade 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 (627) patients with myelodysplastic syndrome (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% (Adverse Events (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. Table 1.
