Dosage and Administration
openFDA Drug Labeling2 DOSAGE AND ADMINISTRATION Take eltrombopag tablets without a meal or with a meal low in calcium (≤ 50 mg). Take eltrombopag tablets at least 2 hours before or 4 hours after any medications or products containing polyvalent cations, such as antacids, calcium-rich foods, and mineral supplements. ( 2.4 , 7.1 , 12.3 ) Persistent or Chronic ITP: Initiate eltrombopag tablets at 50 mg orally once daily for most adult and pediatric patients 6 years and older, and at 25 mg orally once daily for pediatric patients aged 1 to 5 years. Dose reductions are needed for patients with hepatic impairment and some patients of East-/Southeast-Asian ancestry. Adjust to maintain platelet count greater than or equal to 50 x 10 9 /L. Do not exceed 75 mg per day. ( 2.1 , 8.6 , 8.7 ) Chronic Hepatitis C-associated Thrombocytopenia: Initiate eltrombopag tablets at 25 mg orally once daily for all patients. Adjust to achieve target platelet count required to initiate antiviral therapy. Do not exceed a daily dose of 100 mg. ( 2.2 ) First-line Severe Aplastic Anemia: Initiate eltrombopag tablets orally once daily at 2.5 mg/kg (in pediatric patients aged 2 to 5 years old), 75 mg (pediatric patients aged 6 to 11 years old) or 150 mg for patients aged 12 years and older concurrently with standard immunosuppressive therapy. Reduce initial dose in patients of East-/Southeast-Asian ancestry. Modify dosage for toxicity or elevated platelet counts. ( 2.3 , 8.7 ) Refractory Severe Aplastic Anemia: Initiate eltrombopag tablets orally at 50 mg once daily. Reduce initial dose in patients with hepatic impairment or patients of East-/Southeast-Asian ancestry. Adjust to maintain platelet count greater than 50 x 10 9 /L. Do not exceed 150 mg per day. ( 2.3 , 8.6 , 8.7 ) 2.1 Persistent or Chronic Immune Thrombocytopenia Use the lowest dose of eltrombopag tablets to achieve and maintain a platelet count greater than or equal to 50 x 10 9 /L as necessary to reduce the risk for bleeding. Dose adjustments are based upon the platelet count response. Do not use eltrombopag tablets to normalize platelet counts [see Warnings and Precautions (5.4) ]. In clinical trials, platelet counts generally increased within 1 to 2 weeks after starting eltrombopag tablets and decreased within 1 to 2 weeks after discontinuing eltrombopag tablets [see Clinical Studies (14.1) ] . Initial Dose Regimen Adult and Pediatric Patients 6 Years and Older with ITP Initiate eltrombopag tablets at a dose of 50 mg orally once daily, except in patients who are of East-/Southeast-Asian ancestry or who have mild to severe hepatic impairment (Child-Pugh class A, B, C). For patients of East-/Southeast-Asian ancestry with ITP, initiate eltrombopag tablets at a reduced dose of 25 mg orally once daily [see Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ]. For patients with ITP and mild, moderate, or severe hepatic impairment (Child-Pugh class A, B, C), initiate eltrombopag tablets at a reduced dose of 25 mg orally once daily [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] .

Warnings and Cautions
openFDA Drug Labeling5 WARNINGS AND PRECAUTIONS Hepatotoxicity:Monitor liver function before and during therapy. (5.2) Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia.(5.3) Thrombotic/Thromboembolic Complications:Portal vein thrombosis has been reported in patients with chronic liver disease receiving eltrombopag tablets. Monitor platelet counts regularly. (5.4) 5.1 Hepatic Decompensation in Patients With Chronic Hepatitis C In patients with chronic hepatitis C, eltrombopag tablets in combination with interferon and ribavirin may increase the risk of hepatic decompensation. In two controlled clinical trials in patients with chronic hepatitis C and thrombocytopenia, ascites and encephalopathy occurred more frequently on the arm receiving treatment with eltrombopag tablets plus antivirals (7%) than the placebo plus antivirals arm (4%). Patients with low albumin levels (less than 3.5 g/dL) or Model for End-Stage Liver Disease (MELD) score greater than or equal to 10 at baseline had a greater risk for hepatic decompensation on the arm receiving treatment with eltrombopag tablets plus antivirals. Discontinue eltrombopag tablets if antiviral therapy is discontinued. 5.2 Hepatotoxicity Eltrombopag tablets may increase the risk of severe and potentially life-threatening hepatotoxicity [see Adverse Reactions (6.1)] . One patient (< 1%) with ITP treated with eltrombopag tablets in clinical trials experienced drug-induced liver injury. Eleven patients (1%) with chronic hepatitis C treated with eltrombopag tablets in clinical trials experienced drug-induced liver injury. Treatment of ITP, Chronic Hepatitis C-associated Thrombocytopenia, and Refractory Severe Aplastic Anemia Measure serum ALT, AST, and bilirubin prior to initiation of eltrombopag tablets, every 2 weeks during the dose adjustment phase, and monthly following establishment of a stable dose [see Drug Interactions (7.5)] . Eltrombopag tablets inhibits UDP-glucuronosyltransferase (UGT)1A1 and organic anion-transporting polypeptide (OATP)1B1, which may lead to indirect hyperbilirubinemia. If bilirubin is elevated, perform fractionation. Evaluate abnormal serum liver tests with repeat testing within 3 to 5 days. If the abnormalities are confirmed, monitor serum liver tests weekly until resolved or stabilized. Discontinue eltrombopag tablets if ALT levels increase to greater than or equal to 3 x ULN in patients with normal liver function or greater than or equal to 3 x baseline (or greater than 5 x ULN, whichever is the lower) in patients with pre-treatment elevations in transaminases and are: progressively increasing, or persistent for greater than or equal to 4 weeks, or accompanied by increased direct bilirubin, or accompanied by clinical symptoms of liver injury or evidence for hepatic decompensation. If the potential benefit for reinitiating treatment with eltrombopag tablets is considered to outweigh the risk for hepatotoxicity, then consider cautiously reintroducing eltrombopag tablets and measure serum liver tests weekly during the dose adjustment phase. Hepatotoxicity may reoccur if eltrombopag tablets is reinitiated. If liver test abnormalities persist, worsen, or recur, then permanently discontinue eltrombopag tablets. First-Line Treatment of Severe Aplastic Anemia Measure ALT, AST, and bilirubin prior to initiation of eltrombopag tablets, every other day while hospitalized for h-ATG therapy, and then every 2 weeks during treatment. During treatment, manage increases in ALT or AST levels as recommended in Table 6. 5.3 Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia A randomized, double-blind, placebo-controlled, multicenter trial in patients with International Prognostic Scoring System (IPSS) intermediate-1, intermediate-2 or high risk MDS with thrombocytopenia, receiving azacitidine in combination with either eltrombopag tablets (n = 179) or placebo (n = 177) was terminated due to lack of efficacy …
Adverse Reactions
openFDA Drug Labeling6 ADVERSE REACTIONS The following clinically significant adverse reactions associated with eltrombopag are described in other sections. Hepatic Decompensation in Patients with Chronic Hepatitis C [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia [see Warnings and Precautions (5.3) ] Thrombotic/Thromboembolic Complications [see Warnings and Precautions (5.4) ] Cataracts [see Warnings and Precautions (5.5) ] Across all indications, the most common adverse reactions (≥ 20% in any indication) were: anemia, nausea, pyrexia, alanine aminotransferase increased, cough, fatigue, headache, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AvKARE at 1-855-361-3993 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Persistent or Chronic Immune Thrombocytopenia Adults In clinical trials, hemorrhage was the most common serious adverse reaction and most hemorrhagic reactions followed discontinuation of eltrombopag. Other serious adverse reactions included thrombotic/thromboembolic complications [see Warnings and Precautions (5.4) ] . The data described below reflect exposure of eltrombopag to patients with persistent or chronic ITP aged 18 to 85 years, of whom 66% were female, in three placebo-controlled trials and one open-label extension trial [see Clinical Studies (14.1) ] . Eltrombopag was administered to 330 patients for at least 6 months and 218 patients for at least 1 year. Table 8 presents the most common adverse drug reactions (experienced by greater than or equal to 3% of patients receiving eltrombopag) from the three placebo-controlled trials, with a higher incidence in eltrombopag versus placebo.

In the three controlled persistent or chronic ITP trials, serum liver test abnormalities (predominantly Grade 2 or less in severity) were reported in 11% and 7% of patients for eltrombopag and placebo, respectively. Four patients (1%) treated with eltrombopag and three patients in the placebo group (2%) discontinued treatment due to hepatobiliary laboratory abnormalities. Seventeen of the patients treated with eltrombopag in the controlled trials with hepatobiliary laboratory abnormalities were re-exposed to eltrombopag in the extension trial. Eight of these patients again experienced liver test abnormalities (less than or equal to Grade 3) resulting in discontinuation of eltrombopag in one patient. In the extension persistent or chronic ITP trial, six additional patients had eltrombopag discontinued due to liver test abnormalities (less than or equal to Grade 3). In the three controlled persistent or chronic ITP trials, cataracts developed or worsened in 7% of patients treated with eltrombopag and 7% of patients in the placebo group. All patients had documented, preexisting risk factors for cataractogenesis, including corticosteroid use. In the extension trial, cataracts developed or worsened in 11% of patients who underwent ocular examination prior to therapy with eltrombopag. Seventy-tw …
Drug Interactions
openFDA Drug Labeling7 DRUG INTERACTIONS 7.1 Polyvalent Cations (Chelation) Eltrombopag chelates polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc) in foods, mineral supplements, and antacids. Take eltrombopag tablets at least 2 hours before or 4 hours after any medications or products containing polyvalent cations, such as antacids, dairy products, and mineral supplements to avoid significant reduction in absorption of eltrombopag tablets due to chelation [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)] . 7.2 Transporters Use caution when concomitantly administering eltrombopag tablets and drugs that are substrates of OATP1B1 (e.g., atorvastatin, bosentan, ezetimibe, fluvastatin, glyburide, olmesartan, pitavastatin, pravastatin, rosuvastatin, repaglinide, rifampin, simvastatin acid, SN-38 [active metabolite of irinotecan], valsartan) or breast cancer resistance protein (BCRP) (e.g., imatinib, irinotecan, lapatinib, methotrexate, mitoxantrone, rosuvastatin, sulfasalazine, topotecan). Monitor patients closely for signs and symptoms of excessive exposure to the drugs that are substrates of OATP1B1 or BCRP and consider reduction of the dose of these drugs, if appropriate. In clinical trials with eltrombopag tablets, a dose reduction of rosuvastatin by 50% was recommended. 7.3 Protease Inhibitors HIV Protease Inhibitors: No dose adjustment is recommended when eltrombopag tablets are coadministered with lopinavir/ritonavir (LPV/RTV). Drug interactions with other HIV protease inhibitors have not been evaluated. Hepatitis C Virus Protease Inhibitors: No dose adjustments are recommended when eltrombopag tablets are coadministered with boceprevir or telaprevir. Drug interactions with other hepatitis C virus (HCV) protease inhibitors have not been evaluated. 7.4 Peginterferon Alfa-2a/b Therapy No dose adjustments are recommended when eltrombopag tablets are coadministered with peginterferon alfa-2a (PEGASYS ® ) or -2b (PEGINTRON ® ). 7.5 Interference with Clinical Laboratory Tests Eltrombopag is highly colored and can cause patient sample discoloration, which is reported to interfere with some clinical laboratory tests, including, but not limited to bilirubin and creatinine. Bilirubin Testing : Eltrombopag can cause both positive and negative interference with bilirubin assays. If the laboratory results for bilirubin are inconsistent with clinical observations, further evaluation of liver function should be performed to clarify the clinical status of the patient. Evaluating contemporaneous aminotransferase values (AST, ALT) may help determine the validity of normal total bilirubin levels in the presence of clinical jaundice. Creatinine Testing : Eltrombopag can cause positive interference with creatinine measurements, leading to falsely elevated creatinine levels. In the event of an unexpected serum creatinine test result, further evaluation of renal function should be performed. Blood urea should be evaluated if serum creatinine is unexpectedly high. Communicate to the lab conducting testing if the patient is taking eltrombopag tablets. Re-testing using other methods may also help in determining the validity of the test results.
7.1 Polyvalent Cations (Chelation) Eltrombopag chelates polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc) in foods, mineral supplements, and antacids. Take eltrombopag tablets at least 2 hours before or 4 hours after any medications or products containing polyvalent cations, such as antacids, dairy products, and mineral supplements to avoid significant reduction in absorption of eltrombopag tablets due to chelation [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)] .
7.2 Transporters Use caution when concomitantly administering eltrombopag tablets and drugs that are substrates of OATP1B1 (e.g., atorvastatin, bosentan, ezetimibe, fluvastatin, glyburide, olmesartan, pitavastatin, pravastatin, rosuvastatin, repaglinide, rifampin, s …
Use in Specific Populations
openFDA Drug Labeling8 USE IN SPECIFIC POPULATIONS Lactation:Advise women not to breastfeed during treatment. (8.2) 8.1 Pregnancy Risk Summary Available data from a small number of published case reports and postmarketing experience with eltrombopag tablets use in pregnant women are insufficient to assess any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction and developmental toxicity studies, oral administration of eltrombopag to pregnant rats during organogenesis resulted in embryolethality and reduced fetal weights at maternally toxic doses. These effects were observed at doses resulting in exposures that were six times the human clinical exposure based on area under the curve (AUC) in patients with persistent or chronic ITP at 75 mg/day, and three times the AUC in patients with chronic hepatitis C at 100 mg/day (see Data). 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 in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an early embryonic development study, female rats received oral eltrombopag at doses of 10, 20, or 60 mg/kg/day (0.8, 2, and 6 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.3, 1, and 3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day). Increased pre- and post-implantation loss and reduced fetal weight were observed at the highest dose which also caused maternal toxicity. In an embryo-fetal development study eltrombopag was administered orally to pregnant rats during the period of organogenesis at doses of 10, 20, or 60 mg/kg/day (0.8, 2, and 6 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.3, 1, and 3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day). Decreased fetal weights (6% to 7%) and a slight increase in the presence of cervical ribs were observed at the highest dose which also caused maternal toxicity. However, no evidence of major structural malformations was observed. In an embryo-fetal development study eltrombopag was administered orally to pregnant rabbits during the period of organogenesis at doses of 30, 80, or 150 mg/kg/day (0.04, 0.3, and 0.5 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.02, 0.1, and 0.3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day). No evidence of fetotoxicity, embryolethality, or teratogenicity was observed. In a pre- and post-natal developmental toxicity study in pregnant rats (F0), oral eltrombopag was administered from gestation Day 6 through lactation Day 20. No adverse effects on maternal reproductive function or on the development of the offspring (F1) were observed at doses up to 20 mg/kg/day (2 times the human clinical exposure based on AUC in patients with ITP at 75 mg/day and similar to the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day). Eltrombopag was detected in the plasma of offspring (F1). The plasma concentrations in pups increased with dose following administration of drug to the F0 dams. 8.2 Lactation Risk Summary There are no data regarding the presence of eltrombopag or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. However, eltrombopag was detected in the pups of lactating rats 10 days postpartum suggesting the potential for transfer during lactation. Due to the potential for serious adverse reactions in a breastfed child from eltrombopag tablets, breast …
Mechanism of Action
openFDA Drug Labeling12.1 Mechanism of Action Eltrombopag is a TPO-receptor agonist that interacts with the transmembrane domain of the human TPO-receptor (also known as cMpl) and initiates signaling cascades that induce proliferation and differentiation of megakaryocytes leading to increased platelet production.
Description
openFDA Drug Labeling11 DESCRIPTION Eltrombopag tablets contain eltrombopag olamine, a small molecule thrombopoietin (TPO) receptor agonist for oral administration. Eltrombopag olamine is a biphenyl hydrazone. The chemical name for eltrombopag olamine is 3'-{(2Z)-2-[1-(3,4-dimethylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4- ylidene]hydrazino}-2'-hydroxy-3-biphenylcarboxylic acid - 2-aminoethanol (1:2). It has the molecular formula C 25 H 22 N 4 O 4 • 2(C 2 H 7 NO). The molecular weight is 564.65 g/mol for eltrombopag olamine and 442.5 g/mol for eltrombopag free acid. Eltrombopag olamine has the following structural formula: Eltrombopag olamine is practically insoluble in aqueous buffer across a pH range of 1 to 7.4, and is sparingly soluble in water. Eltrombopag tablets contain eltrombopag olamine in the amount equivalent to 12.5 mg, 25 mg, 50 mg, or 75 mg of eltrombopag free acid. The inactive ingredients of eltrombopag tablets are: Tablet Core: microcrystaline cellulose, mannitol, povidone, isomalt, calcium silicate, sodium starch glycolate, and magnesium stearate. Coating: 12.5 mg: hypromellose 2910, titanium dioxide, triacetin. 25 mg: hypromellose 2910, titanium dioxide, triacetin, ferric oxide yellow, ferric oxide red. 50 mg: hypromellose 2910, titanium dioxide, triacetin, FD&C Blue No. 1/brilliant blue FCF aluminum lake, FD&C Blue No. 2/indigo carmine aluminum lake, ferrosoferric oxide. 75 mg: hypromellose 2910, titanium dioxide, triacetin, ferric oxide red. molecule
Overdosage
openFDA Drug Labeling10 OVERDOSAGE In the event of overdose, platelet counts may increase excessively and result in thrombotic/thromboembolic complications. In one report, a subject who ingested 5000 mg of eltrombopag tablets had a platelet count increase to a maximum of 929 x 10 9 /L at 13 days following the ingestion. The patient also experienced rash, bradycardia, ALT/AST elevations, and fatigue. The patient was treated with gastric lavage, oral lactulose, intravenous fluids, omeprazole, atropine, furosemide, calcium, dexamethasone, and plasmapheresis; however, the abnormal platelet count and liver test abnormalities persisted for 3 weeks. After 2 months' follow-up, all events had resolved without sequelae. In case of an overdose, consider oral administration of a metal cation-containing preparation, such as calcium, aluminum, or magnesium preparations to chelate eltrombopag and thus limit absorption. Closely monitor platelet counts. Reinitiate treatment with eltrombopag tablets in accordance with dosing and administration recommendations [see Dosage and Administration (2.1, 2.2)] .
