The following adverse reaction information represents the pooled data collected from single arm or active-controlled clinical trials with FERRIPROX Tablets (deferiprone) (three times a day) or FERRIPROX Oral Solution (deferiprone).
Thalassemia Syndromes The safety of FERRIPROX was evaluated in the pooled clinical trial database [see Clinical Studies ( 14.1 )] .
Patients received FERRIPROX Tablets (three times a day) or FERRIPROX Oral Solution.
FERRIPROX was administered orally three times a day (total daily dose either 50, 75, or 99 mg/kg), N=642.
Among 642 patients receiving FERRIPROX, 492 (76.6%) were exposed for 6 months or longer and 365 (56.9%) were exposed for greater than one year.
The median age of patients who received FERRIPROX was 19 years (range 1, 77 years); 50.2% female; 71.2% White, 17.8% Asian, 9.2% Unknown, 1.2% Multi-racial and 0.6% Black.
The most serious adverse reaction reported in clinical trials with FERRIPROX was agranulocytosis [see Warnings and Precautions ( 5.1 )] .
The most common adverse reactions (≥6%) reported during clinical trials were nausea, vomiting, abdominal pain, arthralgia, alanine aminotransferase increased and neutropenia.
The table below lists the adverse drug reactions that occurred in at least 1% of patients treated with FERRIPROX in clinical trials in patients with thalassemia syndromes.
Table 3: Adverse reactions occurring in ≥ 1% of FERRIPROX-treated patients with thalassemia syndromes * Neutropenia includes events of severe neutropenia (ANC ≥0.2 x 10 9 /L and <0.5 x 10 9 /L).

Chromaturia (reddish/brown discoloration of the urine) is a result of the excretion of iron in the urine.
Sickle Cell Disease or Other Anemias The safety of FERRIPROX compared to deferoxamine was evaluated in LA38-0411 [see Clinical Studies ( 14.2 )] .
Patients received FERRIPROX Tablets or FERRIPROX Oral Solution orally three times a day (total daily dose 75-99 mg/kg/day) n=152) or the control arm, deferoxamine, 20-40 mg/kg/day (children) or 40-50 mg/kg/day (adults), by subcutaneous infusion for 5 – 7 days per week, n=76.
Among 152 patients receiving FERRIPROX, 120 (78.9%) were exposed for 6 months or longer and 17 (11.2%) were exposed for greater than one year.
The median age of patients who received FERRIPROX was 15 years (range 3, 59 years); 54.6% male; 78.9% White, 15.1% Black and 5.9% Multi-racial.
The most common adverse reactions (≥6%) reported during clinical trials in patients with SCD or other anemias were pyrexia, abdominal pain, bone pain, headache, vomiting, pain in extremity, sickle cell anemia with crisis, back pain, alanine aminotransferase (ALT) increased, aspartate aminotransferase (AST) increased, arthralgia, oropharyngeal pain, nasopharyngitis, neutrophil count decreased, cough and nausea.
The table below lists the adverse reactions (irrespective of a causal assessment; adverse events) of interest that occurred in patients treated with FERRIPROX in clinical trials in subjects with sickle cell disease or other anemias.

Pediatric patients (<17 years) had an increase in the following adverse reactions as compared to adults: abdominal pain, neutrophil count decreased, bone pain and oropharyngeal pain.
