Clinical efficacy studies were conducted with deferasirox dispersible tablets.
The absolute bioavailability(AUC) of deferasirox(dispersible tablet formulation) is about 70% compared to an intravenous dose.
Fifty-six patients under the age of 6 years participated in this pivotal study,28 of them receiving deferasirox dispersible tablets.
At a starting dose of 10 mg/kg/day, deferasirox dispersible tablets led to reductions in indicators of total body iron.
The principal analysis of the pivotal comparative study in 586 patients suffering from betathalassaemia andtransfusional iron overload did not demonstrate non-inferiority of deferasirox dispersible tablets to deferoxamine in the analysis of the total patient population.
In a healthy volunteer study, the concomitant administration of deferasirox dispersible tablets and midazolam(a CYP3A4 probe substrate) resulted in a decrease of midazolam exposure by 17%(90% CI: 8%- 26%).
The study compared the efficacy of two different deferasirox dispersible tablet regimens(starting doses of 5 and 10 mg/kg/day, 55 patients in each arm) and of matching placebo(56 patients).
In patients with non-transfusion-dependent thalassaemia syndromes andiron overload, treatment with deferasirox dispersible tablets was assessed in a 1-year, randomised, double-blind, placebo-controlled study.
It appeared from preclinical andclinical studies that deferasirox dispersible tablets could be as active as deferoxamine when used in a dose ratio of 2:1(i.e. a dose of deferasirox dispersible tablets that is numerically half of the deferoxamine dose).
It appeared from a post-hoc analysis of this study that,in the subgroup of patients with liver iron concentration≥7 mg Fe/g dw treated with deferasirox dispersible tablets(20 and 30 mg/kg) or deferoxamine(35 to≥50 mg/kg), the non-inferiority criteria were achieved.
In a healthy volunteer study, the concomitant administration of deferasirox dispersible tablets and midazolam(a CYP3A4 probe substrate) resulted in a decrease of midazolam exposure by 17%(90% CI: 8%- 26%).
During post-marketing experience, hepatic failure, sometimes fatal, has been reported with the deferasirox dispersible tablet formulation, especially in patients with pre-existing liver cirrhosis(see section 4.4).
The most frequent reactions reported during chronic treatment with deferasirox dispersible tablets in adult and paediatric patients include gastrointestinal disturbances(mainly nausea, vomiting, diarrhoea or abdominal pain) and skin rash.
On average, liver iron concentration decreased by 3.80 mg Fe/g dw in patients treated with deferasirox dispersible tablets(starting dose 10 mg/kg/day) and increased by 0.38 mg Fe/g dw in patients treated with placebo(p< 0.001).
Non-interventional post-authorisation safety study(PASS): In order to assess the long-term exposure and safety of deferasirox dispersible and film-coated tablets, the MAH should conduct an observational cohort study in paediatric non-transfusion-dependent thalassaemia patients over 10 years old for whom deferoxamine is contraindicated or inadequate conducted according to a CHMP-agreed protocol.
After adjustment of the strength, the film-coated tablet formulation(360 mg strength)was equivalent to deferasirox dispersible tablets(500 mg strength) with respect to the mean area under the plasma concentration time curve(AUC) under fasting conditions.
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.
On average, serum ferritin decreased by 222.0 µg/l in patients treated with deferasirox dispersible tablets(starting dose 10 mg/kg/day) and increased by 115 µg/l in patients treated with placebo(p< 0.001).
The availability of long-term efficacy and safety data from clinical studies conducted with deferasirox dispersible tablets used at doses above 30 mg/kg is currently limited(264 patients followed for an average of 1 year after dose escalation).
However, in patients with liver iron concentration<7 mg Fe/g dw treated with deferasirox dispersible tablets(5 and 10 mg/kg) or deferoxamine(20 to 35 mg/kg), non-inferiority was not established due to imbalance in the dosing of the two chelators.
In addition, in patients with liver iron concentration≥7 mg Fe/g dw with various rare anaemias orsickle cell disease, deferasirox dispersible tablets up to 20 and 30 mg/kg produced a decrease in liver iron concentration and serum ferritin comparable to that obtained in patients with beta-thalassaemia.
Deferasirox also comes as“dispersible” tablets.
In a study to assess the safety of deferasirox film-coated and dispersible tablets, 173 adult and paediatric patients with transfusion dependent thalassaemia or myelodysplastic syndrome were treated for 24 weeks.
Description of available deferasirox formulations(e.g. dispersible tablets, film-coated tablets and granules) o Different posology regimen o Different conditions of administration o Dose conversion table when switching from one formulation to another.
Bioavailability of deferasirox granules was 52% greater than that with dispersible tablets.
Each dispersible tablet of EXJADE 125 mg contains 125 mg deferasirox.
Bioavailability of deferasirox film-coated tablets was 36% greater than that with dispersible tablets.
Exjade(deferasirox) is now available as film-coated tablets in addition to the already authorised dispersible tablets.
In a healthy volunteer study, the concomitant administration of deferasirox(single dose of 30 mg/kg, dispersible tablet formulation) and the potent UGT inducer, rifampicin,(repeated dose of 600 mg/day) resulted in a decrease of deferasirox exposure by 44%(90% CI: 37%- 51%).
