keting experience, there have been reports of serious adverse reactions, some with a fatal outcome, in patients taking Exjade therapy, predominantly when the drug was administered to patients with advanced age, complications from underlying conditions or very advanced disease. Most of these deaths occurred within six months of Exjade initiation and generally involved worsening of the underlying condition. The reports do not rule out the possibility that Exjade may have contributed to the deaths.
5.8 Special Senses
Auditory disturbances (high frequency hearing loss, decreased hearing), and ocular disturbances (lens opacities, cataracts, elevations in intraocular pressure, and retinal disorders) have been reported at a frequency of <1% with Exjade therapy in the clinical studies. Auditory and ophthalmic testing (including slit lamp examinations and dilated fundoscopy) are recommended before starting Exjade treatment and thereafter at regular intervals (every 12months). If disturbances are noted, consider dose reduction or interruption.
5.9 Laboratory Tests
Measure serum ferritin monthly to assess response to therapy and to eva luate for the possibility of overchelation of iron. If the serum ferritin falls consistently below 500mcg/L, consider temporarily interrupting therapy with Exjade [see Dosage and Administration(2.2)].
In the clinical studies, the correlation coefficient between the serum ferritin and LIC was 0.63. Therefore, changes in serum ferritin levels may not always reliably reflect changes in LIC.
Perform laboratory monitoring of renal and hepatic function [see Warnings and Precautions(5.1,5.3)].
6 ADVERSE REACTIONS
6.1 Clinical Trials Experience
The following adverse reactions are also discussed in other sections of the labeling:
Renal Failure [see Warnings and Precautions (5.1)]. Hepatic Failure [see Warnings and Precautions (5.2)]. Fatal and non-fatal Gastrointestinal Bleedings [see Warnings and Precautions (5.3)]. Cytopenias [see Warnings and Precautions (5.4)].
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.
A total of 700adult and pediatric patients were treated with Exjade (deferasirox) for 48 weeks in premarketing studies. These included 469 patients with ß-thalassemia, 99 with rare anemias, and 132 with sickle cell disease. Of these patients, 45% were male, 70% were Caucasian and 292 patients were < 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 ß-thalassemia and 66 rare anemias) were entered into extensions of the original clinical protocols. In ongoing extension studies, median durations of treatment were 88-205weeks.
Table1 displays adverse reactions occurring in >5% of Exjade-treated β-thalassemia patients (Study1) and sickle cell disease patients (Study 3) with a suspected relationship to study drug. Abdominal pain, nausea, vomiting, diarrhea, skin rashes, and increases in serum creatinine were the most frequent adverse reactions reported with a suspected relationship to Exjade. Gastrointestinal symptoms, increases in serum creatinine, and skin rash were dose rel
