All references to the dispersible tablet formulation throughout the SmPC refer to medicinal products by different Marketing Authorisation Holders with dispersible tablet formulations of the active ingredient deferasirox. Treatment with Deferasirox Mylan should be initiated and maintained by physicians experienced in the treatment of chronic iron overload.
Posology Transfusional iron overload and non-transfusion-dependent thalassaemia syndromes require different posologies. All physicians who intend to prescribe Deferasirox Mylan must ensure they have received and are familiar with the physician educational material (Guide for healthcare professionals which also includes a prescriber checklist).
Transfusional iron overload Doses (in mg/kg body weight) must be calculated and rounded to the nearest whole tablet size. 4). In the EU, medicines containing deferasirox are available as film-coated tablets and dispersible tablets marketed under different tradenames as generic alternatives of deferasirox.

The patient’s response must be monitored, and a dose increase should be considered if sufficient efficacy is not obtained. 7 mg/kg/day Patients who require reduction of elevated body iron levels and who are also receiving >14 ml/kg/month of PRBC (approx >4 units/month for an adult).
21 mg/kg/day Patients who are well managed on deferoxamine. g. a patient receiving 40 mg/kg/day of deferoxamine for 5 days per week [or equivalent] could be transferred to a starting daily dose of 14 mg/kg/day of Deferasirox Mylan film-coated tablets).
1). Dose adjustment It is recommended that serum ferritin be monitored every month and that the dose of Deferasirox be adjusted, if necessary, every 3 to 6 months based on the trends in serum ferritin (see Table 2). 5 to 7 mg/kg/day and are to be tailored to the individual patient’s response and therapeutic goals (maintenance or reduction of iron burden).
Summary of the safety profile The most frequent reactions reported during chronic treatment in clinical studies conducted with deferasirox dispersible tablets in adult and paediatric patients include gastrointestinal disturbances (mainly nausea, vomiting, diarrhoea or abdominal pain) and skin rash.
Diarrhoea is reported more commonly in paediatric patients aged 2 to 5 years and in the elderly. These reactions are dose- dependent, mostly mild to moderate, generally transient and mostly resolve even if treatment is continued. During clinical studies dose-dependent increases in serum creatinine occurred in about 36% of patients, though most remained within the normal range.
Decreases in mean creatinine clearance have been observed in both paediatric and adult patients with beta-thalassemia and iron overload during the first year of treatment, but there is evidence that this does not decrease further in subsequent years of treatment.
Elevations of liver transaminases have been reported. Safety monitoring schedules for renal and liver parameters are recommended. 4). 4). Tabulated list of adverse reactions Adverse reactions are ranked below using the following convention: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be estimated from the available data).
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

Renal function Deferasirox has been studied only in patients with baseline serum creatinine within the age- appropriate normal range. During clinical studies, increases in serum creatinine of >33% on ≥2 consecutive occasions, sometimes above the upper limit of the normal range, occurred in about 36% of patients.
These were dose-dependent. About two-thirds of the patients showing serum creatinine increase returned below the 33% level without dose adjustment. In the remaining third the serum creatinine increase did not always respond to a dose reduction or a dose interruption.
In some cases, only a stabilisation of the serum creatinine values has been observed after dose reduction. 8). In some post-marketing cases, renal function deterioration has led to renal failure requiring temporary or permanent dialysis.
The causes of the rises in serum creatinine have not been elucidated. Particular attention should therefore be paid to monitoring of serum creatinine in patients who are concomitantly receiving medicinal products that depress renal function, and in patients who are receiving high doses of deferasirox and/or low rates of transfusion (<7 ml/kg/month of packed red blood cells or <2 units/month for an adult).
While no increase in renal adverse events was observed after dose escalation of deferasirox dispersible tablets to doses above 30 mg/kg in clinical studies, an increased risk of renal adverse events with film-coated tablet doses above 21 mg/kg cannot be excluded.
It is recommended that serum creatinine be assessed in duplicate before initiating therapy. Serum creatinine, creatinine clearance (estimated with the Cockcroft-Gault or MDRD formula in adults and with the Schwartz formula in children) and/or plasma cystatin C levels should be monitored prior to therapy, weekly in the first month after initiation or modification of therapy with deferasirox (including switch of formulation), and monthly thereafter.
1. 5). Patients with estimated creatinine clearance <60 ml/min.

5 to 7 mg/kg/day. The maximum allowed dose is 28 mg/kg/day. If only very poor haemosiderosis control is achieved at doses up to 21 mg/kg/day, a further increase (to a maximum of 28 mg/kg/day) may not achieve satisfactory control, and alternative treatment options may be considered.
If no satisfactory control is achieved at doses above 21 mg/kg/day, treatment at such doses should not be maintained and alternative treatment options should be considered whenever possible. 5 to 7 mg/kg/day in patients treated with doses >21 mg/kg/day, until the target of 500 to 1 000 μg/l is reached.
5 to 7 mg/kg/day every 3 to 6 months to maintain serum ferritin levels within the target range and to minimise the risk of overchelation. 4). The availability of long-term efficacy and safety data from clinical studies conducted with Deferasirox Mylan dispersible tablets used at doses above 30 mg/kg (equivalent to 21 mg/kg when given as film- coated tablets) is currently limited (264 patients followed for an average of 1 year after dose escalation).
1). 5 Non-transfusion-dependent thalassaemia syndromes Chelation therapy should only be initiated when there is evidence of iron overload (liver iron concentration [LIC] ≥5 mg Fe/g dry weight [dw] or serum ferritin consistently >800 μg/l).
LIC is the preferred method of iron overload determination and should be used wherever available. 4). In the EU, medicines containing deferasirox are available as film-coated tablets and dispersible tablets marketed under different tradenames as generic alternatives of deferasirox.

Patients with pre-existing renal conditions and patients who are receiving medicinal products that depress renal function may be more at risk of complications. Care should be taken to maintain adequate hydration in patients who develop diarrhoea or vomiting.
There have been post-marketing reports of metabolic acidosis occurring during treatment with deferasirox. The majority of these patients had renal impairment, renal tubulopathy (Fanconi syndrome) or diarrhoea, or conditions where acid-base imbalance is a known complication.
Acid- base balance should be monitored as clinically indicated in these populations. Interruption of deferasirox therapy should be considered in patients who develop metabolic acidosis. Post-marketing cases of severe forms of renal tubulopathy (such as Fanconi syndrome) and renal failure associated with changes in consciousness in the context of hyperammonaemic encephalopathy have been reported in patients treated with deferasirox, mainly in children.
It is recommended that hyperammonaemic encephalopathy be considered and ammonia levels measured in patients who develop unexplained changes in mental status while on Deferasirox Mylan therapy. 8 Table 4 Dose adjustment and interruption of treatment for renal monitoring Serum creatinine Creatinine clearance Before initiation of therapy Twice (2×) and Once (1×) Contraindicated <60 ml/min Monitoring – First month after start of therapy or dose modification (including switch of formulation) Weekly and Weekly – Thereafter Monthly and Monthly Reduction of daily dose by 7 mg/kg/day (film-coated tablet formulation), if following renal parameters are observed at two consecutive visits and cannot be attributed to other causes Adult patients >33% above pre-treatment average and Decreases <LLN* (<90 ml/min) Paediatric patients > age appropriate ULN** and/or Decreases <LLN* (<90 ml/min) After dose reduction, interrupt treatment, if Adult and paediatric Remains >33% above pre- treatment average and/or Decreases <LLN* (<90 ml/min) * LLN: lower limit of the normal range ** ULN: upper limit of the normal range Treatment may be reinitiated depending on the individual clinical circumstances.
Dose reduction or interruption may be also considered if abnormalities occur in levels of markers of renal tubular function and/or as clinically indicated: • Proteinuria (test should be performed prior to therapy and monthly thereafter) • Glycosuria in non-diabetics and low levels of serum potassium, phosphate, magnesium or urate, phosphaturia, aminoaciduria (monitor as needed).
Renal tubulopathy has been mainly reported in children and adolescents with beta-thalassaemia treated with Deferasirox Mylan. g. proteinuria, Fanconi Syndrome). Hepatic function Liver function test elevations have been observed in patients treated with deferasirox.
Post- marketing cases of hepatic failure, sometimes fatal, have been reported in patients treated with deferasirox. Severe forms associated with changes in consciousness in the context of hyperammonaemic encephalopathy, may occur in patients treated with deferasirox, particularly in children.
It is recommended that hyperammonaemic encephalopathy be considered and ammonia levels measured in patients who develop unexplained changes in mental status while on Deferasirox Mylan. Care should be taken to maintain adequate hydration in patients who experience volume- depleting events (such as diarrhoea or vomiting), particularly in children with acute illness.
Most reports of hepatic failure involved patients with significant comorbidities including pre-existing chronic liver conditions (including […]
