The limited available data from deferiprone use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. Based on evidence and developmental toxicity in animal studies, deferiprone can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes . In the U.S. general population, the estimated background risk of major birth defects and of miscarriage is 2 to 4% and 15 to 20%, respectively. Data Human Data Post-marketing data available from 39 pregnancies of deferiprone-treated patients and 10 pregnancies of partners of deferiprone-treated patients are as follows: Of the 39 pregnancies in deferiprone-treated patients, 23 resulted in healthy newborns, 6 ended in spontaneous abortion, 9 had unknown outcomes, and 1 infant was born with anal atresia, nephroptosis, ventricular septal defect, hemivertebra and urethral fistula. Of the 10 pregnancies in partners of deferiprone-treated patients, 5 resulted in healthy newborns, 1 resulted in a healthy newborn with slight hypospadias, 1 was electively terminated, 1 resulted in the intrauterine death of twins, and 2 had unknown outcomes. Animal Data During organogenesis, pregnant rats and rabbits received deferiprone at oral doses of 0, 30, 80 or 200 mg/kg/day, and 0, 10, 50, or 150 mg/kg/day, respectively. The daily dose was administered as two equal divided doses approximately 7 hours apart. Doses of 200 mg/kg/day in rats and 150 mg/kg/day in rabbits, approximately 33% and 49% of the MRHD, respectively, resulted in increased post-implantation loss and reduced fetal weights in the presence of maternal toxicity (reduced maternal body weight and body weight gain in both rats and rabbits; abnormal large placenta at low incidence in rats). The 200 mg/kg/day dose in rats resulted in external, visceral and skeletal fetal malformations such as cranial malformations, cleft palate, limb malrotation, anal atresia, internal hydrocephaly, anophthalmia and fused bones. The dose of 150 mg/kg/day in rabbits resulted in external fetal malformations (partially opened eyes) and minor blood vessel and skeletal variations. In rats, malformations including micrognathia and persistent ductus arteriosus could be observed in the absence of maternal toxicity at doses equal to or greater than 30 and 80 mg/kg/day, approximately 5% and 13% of the MHRD, respectively."],"overdosage":["10 OVERDOSAGE No cases of acute overdose have been reported.

The main criterion for chelation failure was serum ferritin > 2,500 mcg/L before treatment with deferiprone. Deferiprone therapy (35 to 99 mg/kg/day) was considered successful in individual patients who experienced a ≥ 20% decline in serum ferritin within one year of starting therapy. Data from a total of 236 patients were analyzed. Of the 224 patients with thalassemia who received deferiprone monotherapy and were eligible for serum ferritin analysis, 105 (47%) were male and 119 (53%) were female. The mean age of these patients was 18.2 years (range 2 to 62; 91 patients were <17). For the patients in the analysis, the endpoint of at least a 20% reduction in serum ferritin was met in 50% (of 236 subjects), with a 95% confidence interval of 43% to 57%. A small number of patients with thalassemia and iron overload were assessed by measuring the change in the number of milliseconds (ms) in the cardiac MRI T2* value before and after treatment with deferiprone for one year. There was an increase in cardiac MRI T2* from a mean at baseline of 11.8 ± 4.9 ms to a mean of 15.1 ± 7.0 ms after approximately one year of treatment. The clinical significance of this observation is not known."],"pharmacodynamics":["12.2 Pharmacodynamics No clinical studies were performed to assess the relationship between the dose of deferiprone and the amount of iron eliminated from the body. Cardiac Electrophysiology At the maximum approved recommended dose, deferiprone does not prolong the QT interval to any clinically relevant extent."],"pharmacokinetics":["12.3 Pharmacokinetics Deferiprone Tablets (three times a day), 1,000 mg and 500 mg The mean C max and AUC of deferiprone was 20 mcg/mL and 50 mcg∙h/mL, respectively, in healthy subjects. The dose proportionality of deferiprone over the approved recommended dosage range is unknown. Absorption Deferiprone appeared in the blood within 5 to 10 minutes after oral administration. Peak serum concentration of deferiprone was reached approximately 1 to 2 hours after a single dose. Effect of Food No clinically significant differences in the pharmacokinetics of deferiprone were observed following administration with food. Elimination The elimination half-life of deferiprone is approximately 2 hours. Metabolism Deferiprone is metabolized primarily by UGT1A6. The major metabolite of deferiprone is the 3- O -glucuronide, which lacks iron binding capability. Excretion Following oral administration, 75% to 90% of the administered dose was recovered in urine (primarily as metabolite) in the first 24 hours. Specific Populations No clinically significant differences in the pharmacokinetics of deferiprone were observed based on sex, race/ethnicity, body weight, mild to severe (eGFR 15 to 89 mL/min/1.73 m 2 ) renal impairment, or mild (Child Pugh Class A) to moderate (Child Pugh Class B) hepatic impairment. The effect of age, including geriatric or pediatric populations, end stage renal disease or severe (Child Pugh Class C) hepatic impairment on the pharmacokinetics of deferiprone is unknown. Drug Interaction Studies In Vitro Studies UGTIA6 Inhibitors: Phenylbutazone (UGT1A6 inhibitor) decreased glucuronidation of deferiprone by up to 78%.

Deferiprone binds with ferric ions to form neutral 3:1 (deferiprone:iron) complexes that are stable at physiological pH. 12.2 Pharmacodynamics No clinical studies were performed to assess the relationship between the dose of deferiprone and the amount of iron eliminated from the body. Cardiac Electrophysiology At the maximum approved recommended dose, deferiprone does not prolong the QT interval to any clinically relevant extent. 12.3 Pharmacokinetics Deferiprone Tablets (three times a day), 1,000 mg and 500 mg The mean C max and AUC of deferiprone was 20 mcg/mL and 50 mcg∙h/mL, respectively, in healthy subjects. The dose proportionality of deferiprone over the approved recommended dosage range is unknown. Absorption Deferiprone appeared in the blood within 5 to 10 minutes after oral administration. Peak serum concentration of deferiprone was reached approximately 1 to 2 hours after a single dose. Effect of Food No clinically significant differences in the pharmacokinetics of deferiprone were observed following administration with food. Elimination The elimination half-life of deferiprone is approximately 2 hours. Metabolism Deferiprone is metabolized primarily by UGT1A6. The major metabolite of deferiprone is the 3- O -glucuronide, which lacks iron binding capability. Excretion Following oral administration, 75% to 90% of the administered dose was recovered in urine (primarily as metabolite) in the first 24 hours. Specific Populations No clinically significant differences in the pharmacokinetics of deferiprone were observed based on sex, race/ethnicity, body weight, mild to severe (eGFR 15 to 89 mL/min/1.73 m 2 ) renal impairment, or mild (Child Pugh Class A) to moderate (Child Pugh Class B) hepatic impairment. The effect of age, including geriatric or pediatric populations, end stage renal disease or severe (Child Pugh Class C) hepatic impairment on the pharmacokinetics of deferiprone is unknown. Drug Interaction Studies In Vitro Studies UGTIA6 Inhibitors: Phenylbutazone (UGT1A6 inhibitor) decreased glucuronidation of deferiprone by up to 78%. Polyvalent Cations: Deferiprone has the potential to bind polyvalent cations (e.g., iron, aluminum, and zinc)."],"indications_and_usage":["1 INDICATIONS AND USAGE Deferiprone tablets are indicated for the treatment of transfusional iron overload in adult patients with thalassemia syndromes when current chelation therapy is inadequate.

( 5.2 ) Zinc Deficiency: Monitor during therapy and supplement for deficiency. ( 5.3 ) Embryo-Fetal Toxicity: Can cause fetal harm. ( 5.4 ) 5.1 Agranulocytosis and Neutropenia Fatal agranulocytosis can occur with deferiprone use. Deferiprone can also cause neutropenia, which may foreshadow agranulocytosis. Measure the absolute neutrophil count (ANC) before starting deferiprone therapy and monitor it regularly while on therapy [see Dosage and Administration (2.1) ] . Reduction in the frequency of ANC monitoring should be considered on an individual patient basis, according to the health care provider's assessment of the patient's understanding of the risk minimization measures required during therapy. Interrupt deferiprone therapy if neutropenia develops (ANC < 1.5 × 10 9 /L). Interrupt deferiprone if infection develops and monitor the ANC frequently. Advise patients taking deferiprone to immediately interrupt therapy and report to their physician if they experience any symptoms indicative of infection. The incidence of agranulocytosis was 1% of patients in pooled clinical trials of 642 patients with thalassemia syndromes. The mechanism of deferiprone-associated agranulocytosis is unknown. Agranulocytosis and neutropenia usually resolve upon discontinuation of deferiprone, but there have been reports of agranulocytosis leading to death. Implement a plan to monitor for and to manage agranulocytosis and neutropenia prior to initiating deferiprone treatment. For agranulocytosis (ANC < 0.2 × 10 9 /L) and severe neutropenia (0.2 x 10 9 /L ≤ ANC < 0.5 x 10 9 /L): Consider hospitalization and other management as clinically appropriate. Do not resume deferiprone in patients who have developed agranulocytosis unless potential benefits outweigh potential risks. Do not rechallenge patients who have developed neutropenia with deferiprone unless potential benefits outweigh potential risks. For neutropenia (ANC < 1.5 × 10 9 /L and ≥ 0.5 × 10 9 /L): Instruct the patient to immediately discontinue deferiprone and all other medications with a potential to cause neutropenia. Obtain a complete blood cell (CBC) count, including a white blood cell (WBC) count corrected for the presence of nucleated red blood cells, an absolute neutrophil count (ANC), and a platelet count daily until recovery (ANC ≥ 1.5 × 10 9 /L). 5.2 Liver Enzyme Elevations In pooled clinical trials, 7.5% of 642 patients with thalassemia syndromes treated with deferiprone developed increased ALT values. Four (0.62%) deferiprone-treated subjects discontinued the drug due to increased serum ALT levels and 1 (0.16%) due to an increase in both ALT and AST. Monitor serum ALT values monthly during therapy with deferiprone and consider interruption of therapy if there is a persistent increase in the serum transaminase levels [see Dosage and Administration (2.1) ] . 5.3 Zinc Deficiency Decreased plasma zinc concentrations have been observed on deferiprone therapy. Monitor plasma zinc annually, and supplement in the event of a deficiency [see Dosage and Administration (2.1) ]. 5.4 Embryo-Fetal Toxicity Based on findings from animal reproduction studies and evidence of genotoxicity, deferiprone can cause fetal harm when administered to a pregnant woman. The available data on the use of deferiprone in pregnant women are insufficient to inform risk. In animal studies, administration of deferiprone during the period of organogenesis resulted in embryo-fetal death and malformations at doses lower than equivalent human clinical doses. Advise pregnant women and females of reproductive potential of the potential risk to the fetus [see Use in Specific Populations (8.1) ] . Advise females of reproductive potential to use an effective method of contraception during treatment with deferiprone and for at least six months after the last dose.

However, in view of the genotoxicity results, and the findings of mammary gland hyperplasia and mammary gland tumors in rats treated with deferiprone in the 52-week toxicology study, tumor formation in carcinogenicity studies must be regarded as likely. Deferiprone was positive in a mouse lymphoma cell assay in vitro . Deferiprone was clastogenic in an in vitro chromosomal aberration test in mice and in a chromosomal aberration test in Chinese Hamster Ovary cells. Deferiprone given orally or intraperitoneally was clastogenic in a bone marrow micronucleus assay in non-iron-loaded mice. A micronucleus test was also positive when mice predosed with iron dextran were treated with deferiprone. Deferiprone was not mutagenic in the Ames bacterial reverse mutation test. A fertility and early embryonic development study of deferiprone was conducted in rats. Sperm counts, motility and morphology were unaffected by treatment with deferiprone. There were no effects observed on male or female fertility or reproductive function at the highest dose which was 25% of the MRHD."],"adverse_reactions_table":["

( 8.2 ) Pediatric use information is approved for Chiesi USA, Inc.'s FERRIPROX® (deferiprone) tablets. However, due to Chiesi USA, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 8.1 Pregnancy Risk Summary In animal reproduction studies, oral administration of deferiprone to pregnant rats and rabbits during organogenesis at doses 33% and 49%, respectively, of the maximum recommended human dose (MRHD) resulted in structural abnormalities, embryo-fetal mortality and alterations to growth (see Data ) . The limited available data from deferiprone use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. Based on evidence and developmental toxicity in animal studies, deferiprone can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes . In the U.S. general population, the estimated background risk of major birth defects and of miscarriage is 2 to 4% and 15 to 20%, respectively. Data Human Data Post-marketing data available from 39 pregnancies of deferiprone-treated patients and 10 pregnancies of partners of deferiprone-treated patients are as follows: Of the 39 pregnancies in deferiprone-treated patients, 23 resulted in healthy newborns, 6 ended in spontaneous abortion, 9 had unknown outcomes, and 1 infant was born with anal atresia, nephroptosis, ventricular septal defect, hemivertebra and urethral fistula. Of the 10 pregnancies in partners of deferiprone-treated patients, 5 resulted in healthy newborns, 1 resulted in a healthy newborn with slight hypospadias, 1 was electively terminated, 1 resulted in the intrauterine death of twins, and 2 had unknown outcomes. Animal Data During organogenesis, pregnant rats and rabbits received deferiprone at oral doses of 0, 30, 80 or 200 mg/kg/day, and 0, 10, 50, or 150 mg/kg/day, respectively. The daily dose was administered as two equal divided doses approximately 7 hours apart. Doses of 200 mg/kg/day in rats and 150 mg/kg/day in rabbits, approximately 33% and 49% of the MRHD, respectively, resulted in increased post-implantation loss and reduced fetal weights in the presence of maternal toxicity (reduced maternal body weight and body weight gain in both rats and rabbits; abnormal large placenta at low incidence in rats). The 200 mg/kg/day dose in rats resulted in external, visceral and skeletal fetal malformations such as cranial malformations, cleft palate, limb malrotation, anal atresia, internal hydrocephaly, anophthalmia and fused bones. The dose of 150 mg/kg/day in rabbits resulted in external fetal malformations (partially opened eyes) and minor blood vessel and skeletal variations. In rats, malformations including micrognathia and persistent ductus arteriosus could be observed in the absence of maternal toxicity at doses equal to or greater than 30 and 80 mg/kg/day, approximately 5% and 13% of the MHRD, respectively. 8.2 Lactation Risk Summary There is no information regarding the presence of deferiprone in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, including the potential for tumorigenicity shown for deferiprone in animal studies, advise patients that breastfeeding is not recommended during treatment with deferiprone, and for at least 2 weeks after the last dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential prior to initiating deferiprone. Contraception Females Deferiprone can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Advise female patients of reproductive potential to use effective contraception during treatment with deferiprone and for at least 6 months after the last dose. Males Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with deferiprone and for at least 3 months after the last dose [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use Safety and effectiveness of deferiprone tablets have not been established in pediatric patients with chronic iron overload due to blood transfusions who are less than 8 years of age. Pediatric use information is approved for Chiesi USA, Inc.'s FERRIPROX® (deferiprone) tablets. However, due to Chiesi USA, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 8.5 Geriatric Use Clinical studies of deferiprone did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

However, in view of the genotoxicity results, and the findings of mammary gland hyperplasia and mammary gland tumors in rats treated with deferiprone in the 52-week toxicology study, tumor formation in carcinogenicity studies must be regarded as likely. Deferiprone was positive in a mouse lymphoma cell assay in vitro . Deferiprone was clastogenic in an in vitro chromosomal aberration test in mice and in a chromosomal aberration test in Chinese Hamster Ovary cells. Deferiprone given orally or intraperitoneally was clastogenic in a bone marrow micronucleus assay in non-iron-loaded mice. A micronucleus test was also positive when mice predosed with iron dextran were treated with deferiprone. Deferiprone was not mutagenic in the Ames bacterial reverse mutation test. A fertility and early embryonic development study of deferiprone was conducted in rats. Sperm counts, motility and morphology were unaffected by treatment with deferiprone. There were no effects observed on male or female fertility or reproductive function at the highest dose which was 25% of the MRHD."]},"tags":[{"label":"Iron Chelator","category":"class"},{"label":"Small Molecule","category":"modality"},{"label":"Deoxyhypusine hydroxylase","category":"target"},{"label":"DOHH","category":"gene"},{"label":"V03AC02","category":"atc"},{"label":"Oral","category":"route"},{"label":"Solution","category":"form"},{"label":"Tablet","category":"form"},{"label":"Generic Available","category":"availability"},{"label":"Active","category":"status"},{"label":"Iron overload","category":"indication"},{"label":"beta Thalassemia","category":"indication"},{"label":"Chiesi","category":"company"},{"label":"Approved 2010s","category":"decade"},{"label":"Chelating Agents","category":"pharmacology"},{"label":"Iron Chelating Agents","category":"pharmacology"},{"label":"Sequestering Agents","category":"pharmacology"}],"phase":"marketed","safety":{"boxedWarnings":["WARNING: AGRANULOCYTOSIS AND NEUTROPENIA Deferiprone can cause agranulocytosis that can lead to serious infections and death.
