Product Labeling Index

Warning: Hepatotoxicity And Risk Of Teratogenicity

• HepatotoxicitySevere liver injury including fatal liver failure has been reported in patients treated with leflunomide, which is indicated for rheumatoid arthritis. A similar risk would be expected for teriflunomide because recommended doses of teriflunomide and leflunomide result in a similar range of plasma concentrations of teriflunomide. Concomitant use of teriflunomide with other potentially hepatotoxic drugs may increase the risk of severe liver injury.Obtain transaminase and bilirubin levels within 6 months before initiation of teriflunomide therapy. Monitor ALT levels at least monthly for six months after starting teriflunomide [see Warnings and Precautions (5.1)]. If drug induced liver injury is suspected, discontinue teriflunomide and start an accelerated elimination procedure with cholestyramine or charcoal [see Warnings and Precautions (5.3)]. Teriflunomide is contraindicated in patients with severe hepatic impairment [see Contraindications (4)]. Patients with pre-existing liver disease may be at increased risk of developing elevated serum transaminases when taking teriflunomide.• Risk of Teratogenicity Teriflunomide is contraindicated for use in pregnant women and in women of reproductive potential who are not using effective contraception because of the potential for fetal harm. Teratogenicity and embryolethality occurred in animals at plasma teriflunomide exposures lower than that in humans. Exclude pregnancy before the start of treatment with teriflunomide in females of reproductive potential. Advise females of reproductive potential to use effective contraception during teriflunomide treatment and during an accelerated drug elimination procedure after teriflunomide treatment. Stop teriflunomide and use an accelerated drug elimination procedure if the patient becomes pregnant [see Contraindications (4) , Warnings and Precautions (5.2,5.3),Use in Specific Populations (8.1) , and Clinical Pharmacology (12.3)].

1 Indications And Usage

Teriflunomide tablet is indicated for the treatment of patients with relapsing forms of multiple sclerosis.

2 Dosage And Administration

  • The recommended dose of teriflunomide tablet is 7 mg or 14 mg orally once daily. Teriflunomide tablet can be taken with or without food.Monitoring to assess safetyObtain transaminase and bilirubin levels within 6 months before initiation of teriflunomide tablet therapy. Monitor ALT levels at least monthly for six months after starting teriflunomide tablets[see Warnings and Precautions (5.1)].Obtain a complete blood cell count (CBC) within 6 months before the initiation of treatment with teriflunomide tablets. Further monitoring should be based on signs and symptoms of infection [see Warnings and Precautions (5.4)].Prior to initiating teriflunomide tablets, screen patients for latent tuberculosis infection with a tuberculin skin test or blood test for mycobacterium tuberculosis infection [see Warnings and Precautions (5.4)].Exclude pregnancy prior to initiation of treatment with teriflunomide tablets in females of reproductive potential [see Warnings and Precautions (5.2)].Check blood pressure before start of teriflunomide tablets treatment and periodically thereafter [see Warnings and Precautions (5.7)].

3 Dosage Forms And Strengths

Teriflunomide tablets are available as 7 mg and 14 mg tablets.Blue colored, pentagonal shaped, biconvex, film coated tablets, debossed with "14" on one side and "T" on other side. Each tablet contains 14 mg of teriflunomide.Light blue colored, hexagonal shaped, biconvex, film coated tablets, debossed with "7" on one side and "T" on other side. Each tablet contains 7 mg of teriflunomide.

4 Contraindications

  • Teriflunomide is contraindicated in/with:Patients with severe hepatic impairment [see Warnings and Precautions (5.1)].Pregnant women and females of reproductive potential not using effective contraception. Teriflunomide may cause fetal harm [see Warnings and Precautions (5.2 and 5.3) and Use in Specific Populations (8.1)].Patients with a history of a hypersensitivity reaction to teriflunomide, leflunomide, or to any of the inactive ingredients in teriflunomide. Reactions have included anaphylaxis, angioedema, and serious skin reactions[see Warnings and Precautions (5.5)].Coadministration with leflunomide [see Clinical Pharmacology (12.3)].

5.1 Hepatotoxicity

Severe liver injury including fatal liver failure and dysfunction has been reported in some patients treated with leflunomide, which is indicated for rheumatoid arthritis. A similar risk would be expected for teriflunomide because recommended doses of teriflunomide and leflunomide result in a similar range of plasma concentrations of teriflunomide. Patients with pre-existing liver disease may be at increased risk of developing elevated serum transaminases when taking teriflunomide. Patients with pre-existing acute or chronic liver disease, or those with serum alanine aminotransferase (ALT) greater than two times the upper limit of normal (ULN) before initiating treatment, should not normally be treated with teriflunomide. Teriflunomide is contraindicated in patients with severe hepatic impairment [see Contraindications (4)].In placebo-controlled trials, ALT greater than three times the ULN occurred in 61/1045 (5.8%) and 62/1002 (6.2%) of patients receiving teriflunomide 7 mg and 14 mg, respectively, and 38/997 (3.8%) of patients receiving placebo, during the treatment period. These elevations occurred mostly within the first year of treatment. Half of the cases returned to normal without drug discontinuation. In clinical trials, if ALT elevation was greater than three times the ULN on two consecutive tests, teriflunomide was discontinued and patients underwent an accelerated elimination procedure [see Warnings and Precautions (5.3)]. Of the patients who underwent discontinuation and accelerated elimination in controlled trials, half returned to normal or near normal values within 2 months.One patient in the controlled trials developed ALT 32 times the ULN and jaundice 5 months after initiation of teriflunomide 14 mg treatment. The patient was hospitalized for 5 weeks and recovered after plasmapheresis and cholestyramine accelerated elimination procedure. Teriflunomide-induced liver injury in this patient could not be ruled out.Obtain serum transaminase and bilirubin levels within 6 months before initiation of teriflunomide therapy. Monitor ALT levels at least monthly for six months after starting teriflunomide. Consider additional monitoring when teriflunomide is given with other potentially hepatotoxic drugs. Consider discontinuing teriflunomide if serum transaminase increase (greater than three times the ULN) is confirmed. Monitor serum transaminase and bilirubin on teriflunomide therapy, particularly in patients who develop symptoms suggestive of hepatic dysfunction, such as unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, or jaundice and/or dark urine. If liver injury is suspected to be teriflunomide -induced, discontinue teriflunomide and start an accelerated elimination procedure [see Warnings and Precautions (5.3)] and monitor liver tests weekly until normalized. If teriflunomide-induced liver injury is unlikely because some other probable cause has been found, resumption of teriflunomide therapy may be considered.

5.2 Teratogenicity

Teriflunomide may cause fetal harm when administered to a pregnant woman. Teratogenicity and embryo-fetal lethality occurred in animal reproduction studies in multiple animal species at plasma teriflunomide exposures similar to or lower than that in humans at the maximum human recommended dose (MHRD) of 14 mg/day [see Use in Specific Populations (8.1) ] . Teriflunomide is contraindicated for use in pregnant women and females of reproductive potential not using effective contraception [see Contraindications (4)and Warnings and Precautions (5.3)] .

5.3 Procedure For Accelerated Elimination Of Teriflunomide

  • Teriflunomide is eliminated slowly from the plasma [see Clinical Pharmacology (12.3)]. Without an accelerated elimination procedure, it takes on average 8 months to reach plasma concentrations less than 0.02 mg/L, although because of individual variations in drug clearance it may take as long as 2 years. An accelerated elimination procedure could be used at any time after discontinuation of teriflunomide. Elimination can be accelerated by either of the following procedures:Administration of cholestyramine 8 g every 8 hours for 11 days. If cholestyramine 8 g three times a day is not well tolerated, cholestyramine 4 g three times a day can be used.Administration of 50 g oral activated charcoal powder every 12 hours for 11 days.If either elimination procedure is poorly tolerated, treatment days do not need to be consecutive unless there is a need to lower teriflunomide plasma concentration rapidly.At the end of 11 days, both regimens successfully accelerated teriflunomide elimination, leading to more than 98% decrease in teriflunomide plasma concentrations.Use of the accelerated elimination procedure may potentially result in return of disease activity if the patient had been responding to teriflunomide treatment.

5.4 Bone Marrow Effects/Immunosuppression Potential/Infections

Bone Marrow EffectsA mean decrease compared to baseline in white blood cell (WBC) count of approximately 15% (mainly neutrophils and lymphocytes) and in platelet count of approximately 10% was observed in placebo- controlled trials with 7 mg and 14 mg of teriflunomide. The decrease in mean WBC count occurred during the first 6 weeks and WBC count remained low during treatment. In placebo-controlled studies, neutrophil count < 1.5x109/L was observed in 12% and 16% of patients receiving teriflunomide 7 mg and 14 mg, respectively, compared with 7% of patients receiving placebo; lymphocyte count <0.8x109/L was observed in 10% and 12% of patients receiving teriflunomide 7 mg and 14 mg, respectively, compared with 6% of patients receiving placebo. No cases of serious pancytopenia were reported in premarketing clinical trials of teriflunomide but rare cases of pancytopenia and agranulocytosis have been reported in the postmarketing setting with leflunomide. A similar risk would be expected for teriflunomide [see Clinical Pharmacology (12.3)].  Cases of thrombocytopenia with teriflunomide, including rare cases with platelet counts less than 50,000/mm3, have been reported in the postmarketing setting. Obtain a complete blood cell count (CBC) within 6 months before the initiation of treatment with teriflunomide. Further monitoring should be based on signs and symptoms suggestive of bone marrow suppression.Risk of Infection/Tuberculosis ScreeningPatients with active acute or chronic infections should not start treatment until the infection(s) is resolved. If a patient develops a serious infection consider suspending treatment with teriflunomide and using an accelerated elimination procedure. Reassess the benefits and risks prior to resumption of therapy. Instruct patients receiving teriflunomide to report symptoms of infections to a physician.Teriflunomide is not recommended for patients with severe immunodeficiency, bone marrow disease, or severe, uncontrolled infections. Medications like teriflunomide that have immunosuppression potential may cause patients to be more susceptible to infections, including opportunistic infections.In placebo-controlled studies of teriflunomide, no overall increase in the risk of serious infections was observed with teriflunomide 7 mg (2.2%) or 14 mg (2.7%) compared to placebo (2.2%). However, one fatal case of klebsiella pneumonia sepsis occurred in a patient taking teriflunomide 14 mg for 1.7 years. Fatal infections have been reported in the post-marketing setting in patients receiving leflunomide, especially Pneumocystis jiroveci pneumonia and aspergillosis. Most of the reports were confounded by concomitant immunosuppressant therapy and/or comorbid illness which, in addition to rheumatoid disease, may predispose patients to infection. In clinical studies with teriflunomide, cytomegalovirus hepatitis reactivation has been observed.In clinical studies with teriflunomide, cases of tuberculosis have been observed. Prior to initiating teriflunomide, screen patients for latent tuberculosis infection with a tuberculin skin test or with a blood test for mycobacterium tuberculosis infection. Teriflunomide has not been studied in patients with a positive tuberculosis screen, and the safety of teriflunomide in individuals with latent tuberculosis infection is unknown. For patients testing positive in tuberculosis screening, treat by standard medical practice prior to therapy with teriflunomide.VaccinationNo clinical data are available on the efficacy and safety of live vaccinations in patients taking teriflunomide. Vaccination with live vaccines is not recommended. The long half-life of teriflunomide should be considered when contemplating administration of a live vaccine after stopping teriflunomide.MalignancyThe risk of malignancy, particularly lymphoproliferative disorders, is increased with the use of some immunosuppressive medications. There is a potential for immunosuppression with teriflunomide. No apparent increase in the incidence of malignancies and lymphoproliferative disorders was reported in the teriflunomide clinical trials, but larger and longer-term studies would be needed to determine whether there is an increased risk of malignancy or lymphoproliferative disorders with teriflunomide.

5.5 Hypersensitivity And Serious Skin Reactions

Teriflunomide can cause anaphylaxis and severe allergic reactions [see Contraindications (4)]. Signs and symptoms have included dyspnea, urticaria, and angioedema including lips, eyes, throat, and tongue.Cases of serious skin reactions, including cases of Stevens-Johnson syndrome (SJS) and a fatal case of toxic epidermal necrolysis (TEN), have been reported with teriflunomide.In patients treated with leflunomide, the parent compound, very rare cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) have also been reported.Inform patients of the signs and symptoms of anaphylaxis and angioedema and signs and symptoms that may signal a serious skin reaction. Inform patients that a fever associated with signs of other organ system involvement (e.g., rash, lymphadenopathy, or hepatic dysfunction) may be drug-related. Instruct patients to discontinue teriflunomide and seek immediate medical care should these signs and symptoms occur. Discontinue teriflunomide, unless the reactions are clearly not drug-related, and begin an accelerated elimination procedure immediately [see Warnings and Precautions (5.3)]. In such cases, patients should not be re-exposed to teriflunomide [see Contraindications (4)].

5.6 Peripheral Neuropathy

In placebo-controlled studies, peripheral neuropathy, including both polyneuropathy and mononeuropathy (e.g., carpal tunnel syndrome), occurred more frequently in patients taking teriflunomide than in patients taking placebo. The incidence of peripheral neuropathy confirmed by nerve conduction studies was 1.4% (13 patients) and 1.9% (17 patients) of patients receiving 7 mg and 14 mg of teriflunomide, respectively, compared with 0.4% receiving placebo (4 patients). Treatment was discontinued in 0.7% (8 patients) with confirmed peripheral neuropathy (3 patients receiving teriflunomide 7 mg and 5 patients receiving teriflunomide 14 mg). Five of them recovered following treatment discontinuation. Not all cases of peripheral neuropathy resolved with continued treatment. Peripheral neuropathy also occurred in patients receiving leflunomide Age older than 60 years, concomitant neurotoxic medications, and diabetes may increase the risk for peripheral neuropathy. If a patient taking teriflunomide develops symptoms consistent with peripheral neuropathy, such as bilateral numbness or tingling of hands or feet, consider discontinuing teriflunomide therapy and performing an accelerated elimination procedure [see Warnings and Precautions (5.3)].

5.7 Increased Blood Pressure

In placebo-controlled studies, the mean change from baseline to the end of study in systolic blood pressure was +2.3 mmHg and +2.7 mmHg for teriflunomide 7 mg and 14 mg, respectively, and -0.6 mmHg for placebo. The change from baseline in diastolic blood pressure was +1.4 mmHg and +1.9 mmHg for teriflunomide 7 mg and 14 mg, respectively, and -0.3 mmHg for placebo. Hypertension was an adverse reaction in 3.1% and 4.3% of patients treated with 7 mg or 14 mg of teriflunomide compared with 1.8% for placebo. Check blood pressure before start of teriflunomide treatment and periodically thereafter. Elevated blood pressure should be appropriately managed during treatment with teriflunomide.

5.8 Respiratory Effects

Interstitial lung disease, including acute interstitial pneumonitis, has been reported with teriflunomide in the postmarketing setting.Interstitial lung disease and worsening of pre-existing interstitial lung disease have been reported during treatment with leflunomide. Interstitial lung disease may be fatal and may occur acutely at any time during therapy with a variable clinical presentation. New onset or worsening pulmonary symptoms, such as cough and dyspnea, with or without associated fever, may be a reason for discontinuation of therapy and for further investigation as appropriate. If discontinuation of the drug is necessary, consider initiation of an accelerated elimination procedure [see Warnings and Precautions (5.3)].

5.9 Concomitant Use With Immunosuppressive Or Immunomodulating Therapies

Co-administration with antineoplastic, or immunosuppressive therapies used for treatment of multiple sclerosis has not been evaluated. Safety studies in which teriflunomide was concomitantly administered with other immune modulating therapies for up to one year (interferon beta, glatiramer acetate) did not reveal any specific safety concerns. The long term safety of these combinations in the treatment of multiple sclerosis has not been established.In any situation in which the decision is made to switch from teriflunomide to another agent with a known potential for hematologic suppression, it would be prudent to monitor for hematologic toxicity, because there will be overlap of systemic exposure to both compounds. Use of an accelerated elimination procedure may decrease this risk, but may also potentially result in return of disease activity if the patient had been responding to teriflunomide treatment [see Warnings and Precautions (5.3)].

6 Adverse Reactions

  • The following serious adverse reactions are described elsewhere in the prescribing information:Hepatotoxicity [see Contraindications (4) and Warnings and Precautions (5.1)]Bone Marrow Effects /Immunosuppression Potential/Infections [see Warnings and Precautions (5.4)]Hypersensitivity and Serious Skin Reactions [see Contraindications (4) and Warnings and Precautions (5.5)]Peripheral Neuropathy [see Warnings and Precautions (5.6)]Increased Blood Pressure [see Warnings and Precautions (5.7)]Respiratory Effects [see Warnings and Precautions (5.8)]

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 to rates in the clinical  trials of another drug and may not reflect the rates observed in clinical  practice.A total of 2047 patients receiving teriflunomide (7 mg or 14 mg once daily) constituted the  safety population in the pooled analysis of placebo controlled studies in patients with relapsing forms  of multiple sclerosis; of these, 71% were female. The average age was 37  years.Table 1 lists adverse reactions in placebo-controlled trials with rates that were at least 2%  for teriflunomide patients and also at least 2% above the rate in placebo patients. The most  common were headache, an increase in ALT, diarrhea, alopecia, and nausea. The adverse reaction  most commonly associated with discontinuation was an increase in ALT (3.3%, 2.6%, and 2.3% of  all patients in the teriflunomide 7 mg, teriflunomide 14 mg, and placebo treatment arms,  respectively).Table 1. Adverse Reactions in Pooled Placebo-Controlled Studies in Patients  with  Relapsing Forms of Multiple  Sclerosis                                                               Adverse Reaction  Teriflunomide 7 mg (N=1045)  Teriflunomide 14 mg (N=1002)  Placebo (N=997)  Headache  18%  16%  15%  Increase in Alanine aminotransferase  13%  15%  9%  Diarrhea  13%  14%  8%  Alopecia  10%  13%  5%  Nausea  8%  11%  7%  Paresthesia  8%  9%  7%  Arthralgia  8%  6%  5%  Neutropenia  4%  6%  2%  Hypertension  3%  4%  2%  Cardiovascular  deathsFour cardiovascular deaths, including three sudden deaths, and one myocardial infarction in  a patient with a history of hyperlipidemia and hypertension were reported among  approximately 2600 patients exposed to teriflunomide in the premarketing database. These cardiovascular  deaths occurred during uncontrolled extension studies, one to nine years after initiation of treatment.  A relationship between teriflunomide and cardiovascular death has not been  established.Acute Renal FailureIn placebo-controlled studies, creatinine values increased more than 100% over baseline  in 8/1045 (0.8%) patients in the 7 mg teriflunomide group and 6/1002 (0.6%) patients in the 14  mg teriflunomide group versus 4/997 (0.4%) patients in the placebo group. These elevations  were transient. Some elevations were accompanied by hyperkalemia. Teriflunomide may cause acute  uric acid nephropathy with transient acute renal failure because teriflunomide increases renal uric  acid clearance.Hypophosphatemia In clinical trials, 18% of teriflunomide -treated patients had hypophosphatemia with  serum phosphorus levels of at least 0.6 mmol/L, compared to 7% of placebo-treated patients; 4%  of teriflunomide -treated patients had hypophosphatemia with serum phosphorus levels at least  0.3 mmol/L but less than 0.6 mmol/L, compared to 0.8% of placebo-treated patients. No patient  in any treatment group had a serum phosphorus below 0.3  mmol/L.

6.2 Postmarketing Experience

  • The following adverse reactions have been identified during post approval use of teriflunomide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.Hypersensitivity reactions, some of which were severe, such as anaphylaxis and angioedema [see Warnings and Precautions (5.5)]Severe skin reactions, including toxic epidermal necrolysis and Stevens-Johnson syndrome [see Warnings and Precautions (5.5)]Thrombocytopenia [see Warnings and Precautions (5.4)]Interstitial lung disease [see Warnings and Precautions (5.8)]Pancreatitis

7 Drug Interactions

Effect of teriflunomide on CYP2C8 substratesTeriflunomide is an inhibitor of CYP2C8 in vivo. In patients taking teriflunomide, exposure of drugs metabolized by CYP2C8 (e.g., paclitaxel, pioglitazone, repaglinide, rosiglitazone) may be increased. Monitor these patients and adjust the dose of the concomitant drug(s) metabolized by CYP2C8 as required [see Clinical Pharmacology (12.3)].Effect of teriflunomide on warfarinCoadministration of teriflunomide with warfarin requires close monitoring of the international normalized ratio (INR) because teriflunomide may decrease peak INR by approximately 25%.Effect of teriflunomide on oral contraceptivesTeriflunomide may increase the systemic exposures of ethinylestradiol and levonorgestrel. Consideration should be given to the type or dose of contraceptives used in combination with teriflunomide [see Clinical Pharmacology (12.3)].Effect of teriflunomide on CYP1A2 substratesTeriflunomide may be a weak inducer of CYP1A2 in vivo. In patients taking teriflunomide, exposure of drugs metabolized by CYP1A2 (e.g., alosetron, duloxetine, theophylline, tizanidine) may be reduced. Monitor these patients and adjust the dose of the concomitant drug(s) metabolized by CYP1A2 as required [see Clinical Pharmacology (12.3)].Effect of teriflunomide on organic anion transporter 3 (OAT3) substratesTeriflunomide inhibits the activity of OAT3 in vivo. In patients taking teriflunomide, exposure of drugs which are OAT3 substrates (e.g., cefaclor, cimetidine, ciprofloxacin, penicillin G, ketoprofen, furosemide, methotrexate, zidovudine) may be increased. Monitor these patients and adjust the dose of the concomitant drug(s) which are OAT3 substrates as required [see Clinical Pharmacology (12.3)].Effect of teriflunomide on BCRP and organic anion transporting polypeptide B1 and B3 (OATP1B1/1B3) substratesTeriflunomide inhibits the activity of BCRP and OATP1B1/1B3 in vivo. For a patient taking teriflunomide, the dose of rosuvastatin should not exceed 10 mg once daily.  For other substrates of BCRP (e.g., mitoxantrone) and drugs in the OATP family (e.g., methotrexate, rifampin), especially HMG-Co reductase inhibitors (e.g., atorvastatin, nateglinide, pravastatin, repaglinide, and simvastatin), consider reducing the dose of these drugs and monitor patients closely for signs and symptoms of increased exposures to the drugs while patients are taking teriflunomide [see Clinical Pharmacology (12.3)].

8.1 Pregnancy

Risk Summary Teriflunomide is contraindicated for use in pregnant women and females of reproductive potential not using effective contraception because of the potential for fetal harm based on animal data. Human data are not available at this time to inform the presence or absence of drug-associated risk with the use of teriflunomide during pregnancy. In animal reproduction studies in rat and rabbits, oral administration of teriflunomide during organogenesis caused teratogenicity and embryolethality at plasma exposures (AUC) lower than that at the maximum human recommended dose (MHRD) of 14 mg/day [see Data]. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The background risk of major birth defects and miscarriage in the indicated population is unknown.Clinical Considerations Women who wish to become pregnant should discontinue use of teriflunomide and undergo an accelerated elimination procedure to decrease the plasma concentration of teriflunomide to less than 0.02 mg/L (0.02 mcg/mL). Effective contraception should be used until is it verified that plasma concentrations of teriflunomide are less than 0.02 mg/L (0.02 mcg/mL) [see Warnings and Precautions (5.3) ]. Human plasma concentrations of teriflunomide less than 0.02 mg/L (0.02 mcg/mL) are expected to have minimal embryofetal risk [see Contraindications (4)and Warnings and Precautions (5.3) ]. If the patient becomes pregnant while taking this drug, stop treatment with teriflunomide, inform the patient of the potential risk to the fetus, and perform the accelerated drug elimination procedure to achieve plasma concentrations of less than 0.02 mg/L (0.02 mcg/mL) [see Warnings and Precautions (5.3)and Clinical Pharmacology (12.3) ]. Refer the patient to an obstetrician/gynecologist, preferably experienced in reproductive toxicity, for further evaluation and counseling [see Warnings and Precautions (5.2,5.3) ].Data Animal Data When teriflunomide (oral doses of 1, 3, or 10 mg/kg/day) was administered to pregnant rats throughout the period of organogenesis, high incidences of fetal malformation (primarily craniofacial, and axial and appendicular skeletal defects) and embryofetal death were observed at doses not associated with maternal toxicity. Adverse effects on embryofetal development were observed following dosing at various stages throughout organogenesis. Maternal plasma exposure at the no-effect level (1 mg/kg/day) for embryofetal developmental toxicity in rats was less than that in humans at the maximum recommended human dose (MRHD, 14 mg/day). Administration of teriflunomide (oral doses of 1, 3.5, or 12 mg/kg/day) to pregnant rabbits throughout organogenesis resulted in high incidences of fetal malformation (primarily craniofacial, and axial and appendicular skeletal defects) and embryofetal death at doses associated with minimal maternal toxicity. Maternal plasma exposure at the no-effect dose (1 mg/kg/day) for embryofetal developmental toxicity in rabbits was less than that in humans at the MRHD. In studies in which teriflunomide (oral doses of 0.05, 0.1, 0.3, 0.6, or 1.0 mg/kg/day) was administered to rats during gestation and lactation, decreased growth, eye and skin abnormalities, and high incidences of malformation (limb defects) and postnatal death were observed in the offspring at doses not associated with maternal toxicity. Maternal plasma exposure at the no- effect dose for pre- and postnatal developmental toxicity in rats (0.10 mg/kg/day) was less than that in humans at the MRHD. In animal reproduction studies of leflunomide, embryolethality and teratogenic effects were observed in pregnant rat and rabbit at or below clinically relevant plasma teriflunomide exposures (AUC). In published reproduction studies in pregnant mice, leflunomide was embryolethal and increased the incidence of malformations (craniofacial, axial skeletal, heart and great vessel). Supplementation with exogenous uridine reduced the teratogenic effects in pregnant mice, suggesting that the mode of action (inhibition of mitochondrial enzyme dihydroorotate dehydrogenase) is the same for therapeutic efficacy and developmental toxicity. At recommended doses in humans, teriflunomide and leflunomide result in a similar range of plasma concentrations of teriflunomide.

8.2 Lactation

Risk Summary It is not known whether this drug is excreted in human milk. Teriflunomide was detected in rat milk following a single oral dose. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for teriflunomide and any potential adverse effects on the breastfed infant from teriflunomide or from the underlying maternal condition.

8.3 Females And Males Of Reproductive Potential

Pregnancy Testing Exclude pregnancy prior to initiation of treatment with teriflunomide in females of reproductive potential. Advise females to notify their healthcare provider immediately if pregnancy occurs or is suspected during treatment [see Warnings and Precautions (5.2,5.3) and Use in Specific Populations (8.1)].Contraception Females Females of reproductive potential should use effective contraception while taking teriflunomide. If teriflunomide is discontinued, use of contraception should be continued until is it verified that plasma concentrations of teriflunomide are less than 0.02 mg/L (0.02 mcg/mL). Females of reproductive potential who wish to become pregnant should undergo an accelerated elimination procedure. Effective contraception should be used until it is verified that plasma concentrations of teriflunomide are less than 0.02 mg/L (0.02 mcg/mL) [see Warnings and Precautions (5.3) ]. Males Teriflunomide is detected in human semen. Animal studies to specifically evaluate the risk of male- mediated fetal toxicity have not been conducted. To minimize any possible risk, men not wishing to father a child and their female partners should use effective contraception. Men wishing to father a child should discontinue use of teriflunomide and either undergo an accelerated elimination procedure or wait until verification that the plasma teriflunomide concentration is less than 0.02 mg/L (0.02  mcg/mL) [see Warnings and Precautions (5.3)].Infertility Administration of teriflunomide to male rats resulted in no adverse effects on fertility. However, reduced epididymal sperm count was observed [see Nonclinical Toxicology (13.1)]. Effects of teriflunomide on fertility in humans have not been evaluated.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of teriflunomide did not include patients over 65 years old.

8.6 Hepatic Impairment

No dosage adjustment is necessary for patients with mild and moderate hepatic impairment. The pharmacokinetics of teriflunomide in severe hepatic impairment have not been evaluated. Teriflunomide is contraindicated in patients with severe hepatic impairment [see Contraindications (4), Warnings and Precautions (5.1), and Clinical Pharmacology (12.3)].

8.7 Renal Impairment

No dosage adjustment is necessary for patients with mild, moderate, and severe renal impairment [see Clinical Pharmacology (12.3)].

10 Overdosage

There is no experience regarding teriflunomide overdose or intoxication in humans. Teriflunomide 70 mg daily up to 14 days was well tolerated by healthy subjects.In the event of clinically significant overdose or toxicity, cholestyramine or activated charcoal is recommended to accelerate elimination [see Warnings and Precautions (5.3)].

11 Description

Teriflunomide is an oral de novo pyrimidine synthesis inhibitor of the DHO-DH enzyme, with the chemical name (Z)-2-Cyano-3-hydroxy-but-2-enoic acid-(4-trifluoro methyl phenyl)-amide. Its molecular weight is 270.21, and the structural formula is C12H9F3N2O2 with the following chemical structure:Teriflunomide is a white to almost white powder that is soluble in N, N-Dimethyl formamide, sparingly soluble in acetone and insoluble in water.Teriflunomide is formulated as film-coated tablets for oral administration. Teriflunomide tablets contain 7 mg or 14 mg of teriflunomide and the following inactive ingredients:  colloidal silicon dioxide, corn starch, hydroxy propyl cellulose, lactose monohydrate, magnesium stearate and sodium starch glycolate. The film coating for the 14 mg tablet is made of hypromellose, titanium dioxide, polyethylene glycol indigo carmine aluminum lake and iron oxide yellow. In addition to these, the 7 mg tablet film coating includes talc and brilliant blue aluminum lake.

12.1 Mechanism Of Action

Teriflunomide, an immunomodulatory agent with anti-inflammatory properties, inhibits dihydroorotate dehydrogenase, a mitochondrial enzyme involved in de novo pyrimidine synthesis. The exact mechanism by which teriflunomide exerts its therapeutic effect in multiple sclerosis is unknown but may involve a reduction in the number of activated lymphocytes in CNS.

12.2 Pharmacodynamics

Potential to prolong the QT intervalIn a placebo controlled thorough QT study performed in healthy subjects, there was no evidence that teriflunomide caused QT interval prolongation of clinical significance (i.e., the upper bound of the 90% confidence interval for the largest placebo-adjusted, baseline-corrected QTc was below 10 ms).

12.3 Pharmacokinetics

  • Teriflunomide is the principal active metabolite of leflunomide and is responsible for leflunomide’s activity in vivo. At recommended doses, teriflunomide and leflunomide result in a similar range of plasma concentrations of teriflunomide.Based on a population analysis of teriflunomide in healthy volunteers and MS patients, median t1/2 was approximately 18 and 19 days after repeated doses of 7 mg and 14 mg respectively. It takes approximately 3 months respectively to reach steady-state concentrations. The estimated AUC accumulation ratio is approximately 30 after repeated doses of 7 or 14 mg.AbsorptionMedian time to reach maximum plasma concentrations is between 1 to 4 hours post dose following oral administration of teriflunomide. Food does not have a clinically relevant effect on teriflunomide pharmacokinetics. DistributionTeriflunomide is extensively bound to plasma protein (>99%) and is mainly distributed in plasma. The volume of distribution is 11 L after a single intravenous (IV) administration.MetabolismTeriflunomide is the major circulating moiety detected in plasma. The primary biotransformation pathway to minor metabolites of teriflunomide is hydrolysis, with oxidation being a minor pathway. Secondary pathways involve oxidation, N-acetylation and sulfate conjugation.EliminationTeriflunomide is eliminated mainly through direct biliary excretion of unchanged drug as well as renal excretion of metabolites. Over 21 days, 60.1% of the administered dose is excreted via feces (37.5%) and urine (22.6%). After an accelerated elimination procedure with cholestyramine, an additional 23.1% was recovered (mostly in feces). After a single IV administration, the total body clearance of teriflunomide is 30.5 mL/h.Drug Interaction StudiesTeriflunomide is not metabolized by Cytochrome P450 or flavin monoamine oxidase enzymes. The Potential Effect of teriflunomide on Other DrugsCYP2C8 SubstratesThere was an increase in mean repaglinide Cmax and AUC (1.7- and 2.4-fold, respectively), following repeated doses of teriflunomide and a single dose of 0.25 mg repaglinide, suggesting that teriflunomide is an inhibitor of CYP2C8 in vivo. The magnitude of interaction could be higher at the recommended repaglinide dose [see Drug Interactions (7) ].CYP1A2 SubstratesRepeated doses of teriflunomide decreased mean Cmax and AUC of caffeine by 18% and 55%, respectively, suggesting that teriflunomide may be a weak inducer of CYP1A2 in vivo [see Drug Interactions (7)].OAT3 SubstratesThere was an increase in mean cefaclor Cmaxand AUC (1.43- and 1.54-fold, respectively), following repeated doses of teriflunomide, suggesting that teriflunomide is an inhibitor of organic anion transporter 3 (OAT3) in vivo [see Drug Interactions (7)].BCRP and OATP1B1/1B3 Substrates There was an increase in mean rosuvastatin Cmax and AUC (2.65- and 2.51-fold, respectively), following repeated doses of teriflunomide , suggesting that teriflunomide is an inhibitor of BCRP transporter and organic anion transporting polypeptide 1B1 and 1B3 (OATP1B1/1B3) [see Drug Interactions (7)].Oral ContraceptivesThere was an increase in mean ethinylestradiol Cmaxand AUC0-24(1.58- and 1.54-fold, respectively) and levonorgestrel Cmaxand AUC0-24(1.33- and 1.41-fold, respectively) following repeated doses of teriflunomide [see Drug Interactions (7)].Teriflunomide did not affect the pharmacokinetics of bupropion (a CYP2B6 substrate), midazolam (a CYP3A4 substrate), S-warfarin (a CYP2C9 substrate), omeprazole (a CYP2C19 substrate), and metoprolol (a CYP2D6 substrate). The Potential Effect of Other Drugs on teriflunomidePotent CYP and transporter inducers: Rifampin did not affect the pharmacokinetics of teriflunomide.Specific populationsHepatic ImpairmentMild and moderate hepatic impairment had no impact on the pharmacokinetics of teriflunomide. The pharmacokinetics of teriflunomide in severe hepatic impairment have not been evaluated [see Contraindications (4), Warnings and Precautions (5.1), and Use in Specific Populations (8.6)].Renal ImpairmentSevere renal impairment had no impact on the pharmacokinetics of teriflunomide [see Use in Specific Populations (8.7)].GenderIn a population analysis, the clearance rate for teriflunomide is 23% less in females than in males.RaceEffect of race on the pharmacokinetics of teriflunomide cannot be adequately assessed due to a low number of non-white patients in the clinical trials.

13.1 Carcinogenesis, Mutagenesis , Impairment Of Fertility

CarcinogenesisNo evidence of carcinogenicity was observed in lifetime carcinogenicity bioassays in mouse and rat. In mouse, teriflunomide was administered orally at doses up to 12 mg/kg/day for up to 95­-104 weeks; plasma teriflunomide exposures (AUC) at the highest dose tested are approximately 3 times that in humans at the maximum recommended human dose (MRHD, 14 mg/day). In rat, teriflunomide was administered orally at doses up to 4 mg/kg/day for up to 97-104 weeks; plasma teriflunomide AUCs at the highest doses tested are less than that in humans at the MRHD.MutagenesisTeriflunomide was negative in the in vitro bacterial reverse mutation (Ames) assay, the in vitro HPRT assay, and in in vivo micronucleus and chromosomal aberration assays. Teriflunomide was positive in an in vitro chromosomal aberration assay in human lymphocytes, with and without metabolic activation. Addition of uridine (to supplement the pyrimidine pool) reduced the magnitude of the clastogenic effect; however, teriflunomide was positive in the in vitro chromosomal aberration assay, even in the presence of uridine.4-Trifluoromethylaniline (4-TFMA), a minor metabolite of teriflunomide, was positive in the in vitro bacterial reverse mutation (Ames) assay, the in vitro HPRT assay, and the in vitro chromosomal aberration assay in mammalian cells. 4-TFMA was negative in in vivo micronucleus and chromosomal aberration assays.Impairment of fertilityOral administration of teriflunomide (0, 1, 3, 10 mg/kg/day) to male rats prior to and during mating (to untreated females) resulted in no adverse effects on fertility; however, reduced epididymal sperm count was observed at the mid and high doses tested. The no-effect dose for reproductive toxicity in male rats (1 mg/kg) is less than the MRHD on a mg/m2 basis.Oral administration of teriflunomide (0, 0.84, 2.6, 8.6 mg/kg/day) to female rats, prior to and during mating (to untreated males) and continuing to gestation day 6, resulted in embryolethality, reduced fetal body weight, and/or malformations at all doses tested. Due to marked embryolethality at the highest dose tested, no fetuses were available for evaluation. The lowest dose tested is less than the MRHD on a mg/m2 basis.

14 Clinical Studies

Four randomized, controlled, double-blind clinical trials established the efficacy of  teriflunomide in patients with relapsing forms of multiple  sclerosis.Study 1 was a double-blind, placebo-controlled clinical trial that evaluated once daily doses  of teriflunomide 7 mg and teriflunomide 14 mg for up to 26 months in patients with relapsing forms  of multiple sclerosis. Patients were required to have a diagnosis of multiple sclerosis exhibiting  a relapsing clinical course, with or without progression, and to have experienced at least  one relapse over the year preceding the trial or at least two relapses over the two years preceding  the trial. Patients were required not to have received interferon-beta for at least four months, or  any other multiple sclerosis medication for at least six months before entering the study, nor  were these medications permitted during the study. Neurological evaluations were to be performed  at  screening, every 12 weeks until week 108, and after suspected relapses. MRI was to  be performed at screening, and at Week 24, 48, 72, and 108. The primary endpoint was  the annualized relapse rate  (ARR).In Study 1, 1088 patients were randomized to receive teriflunomide 7 mg (n=366),  teriflunomide 14 mg (n=359), or placebo (n=363). At entry, patients had an Expanded Disability Status  Scale (EDSS) score ≤5.5. Patients had a mean age of 38 years, mean disease duration of 5 years,  and mean EDSS at baseline of 2.7. A total of 91% of patients had relapsing remitting  multiple sclerosis, and 9% had a progressive form of multiple sclerosis with relapses. The mean  duration of treatment was 635, 627, and 631 days for teriflunomide 7 mg, teriflunomide 14 mg, and  placebo, respectively. The percentage of patients who completed the study treatment period was  75%, 73%, and 71% for teriflunomide 7 mg, teriflunomide 14 mg, and placebo,  respectively.There was a statistically significant reduction in ARR for patients who received teriflunomide 7  mg or  teriflunomide  14  mg,  compared  to  patients  who  received  placebo  (see  Table  2).  There  was  a consistent  reduction  of  the  ARR  noted  in  subgroups  defined  by  sex,  age  group,  prior  multiple sclerosis therapy, and baseline disease  activity.There was a statistically significant reduction in the relative risk of  disability progression  at  week 108 sustained for 12 weeks (as measured by at least a 1-point increase from baseline  EDSS ≤ 5.5 or a 0.5 point increase for those with a baseline EDSS > 5.5) in the teriflunomide 14  mg  group compared to placebo (see Table 2 and Figure  1).The effect of teriflunomide on several magnetic resonance imaging (MRI) variables including the total lesion volume of T2 and hypointense T1 lesions, was assessed in Study 1. The change in total lesion volume from baseline was significantly lower in the teriflunomide 7 mg and teriflunomide 14 mg groups than in the placebo group. Patients in both teriflunomide groups had significantly fewer gadolinium-enhancing lesions per T1-weighted scan than those in the placebo group (see Table 2).Table 2.

Patients were required to have a diagnosis of multiple sclerosis exhibiting  a relapsing clinical course and to have experienced at least one relapse over the year preceding  the trial, or at least two relapses over the two years preceding the trial. Patients were required not  to have received any multiple sclerosis medication for at least three months before entering  the trial, nor were these medications permitted during the trial. Neurological evaluations were to  be performed at screening, every 12 weeks until completion, and after every suspected relapse.  The primary end point was the  ARR.A total of 1165 patients received teriflunomide 7 mg (n=407), teriflunomide 14 mg (n=370),  or placebo (n=388). Patients had a mean age of 38 years, a mean disease duration of 5 years, and  a mean EDSS at baseline of 2.7. A total of 98% of patients had relapsing remitting  multiple sclerosis, and 2% had a progressive form of multiple sclerosis with relapses. The mean  duration of treatment was 552, 567, and 571 days for teriflunomide 7 mg, teriflunomide 14 mg, and  placebo, respectively. The percentage of patients who completed the study treatment period was  67%, 66%, and 68% for teriflunomide 7 mg, teriflunomide 14 mg, and placebo,  respectively.There was a statistically significant reduction in the ARR for patients who received teriflunomide  7 mg or teriflunomide 14 mg compared to patients who received placebo (see Table 3). There was  a consistent reduction of the ARR noted in subgroups defined by sex, age group, prior  multiple sclerosis therapy, and baseline disease  activity.There was a statistically significant reduction in the relative risk of disability progression at week 108 sustained for 12 weeks (as measured by at least a 1-point increase from baseline EDSS ≤ 5.5 or a 0.5 point increase for those with a baseline EDSS > 5.5) in the teriflunomide 14 mg group compared to placebo  (See Table 3 and Figure 2).Table 3.

Other

Study 3 was a double-blind, placebo-controlled clinical trial that evaluated once daily doses  of teriflunomide 7 mg and teriflunomide 14 mg for up to 108 weeks in patients with relapsing  multiple sclerosis. Patients were required to have had a first clinical event consistent with  acute demyelination occurring within 90 days of randomization with 2 or more T2 lesions at least  3 mm in diameter that were characteristic of multiple sclerosis. A total of 614 patients  received teriflunomide 7 mg (n=203), teriflunomide 14 mg (n=214), or placebo (n=197). Patients had a  mean  age of 32 years, EDSS at baseline of 1.7, and mean disease duration of two months.  The proportion of patients free of relapse was greater in the teriflunomide 7 mg (70.5%, p < 0.05)  and teriflunomide 14 mg (72.2%, p < 0.05) groups than in the placebo group  (61.7%).The effect of teriflunomide on MRI activity was also demonstrated in Study 4, a  randomized, double-blind, placebo-controlled clinical trial of multiple sclerosis patients with relapse. In  Study 4, MRI was to be performed at baseline, 6 weeks, 12 weeks, 18 weeks, 24 weeks, 30 weeks,  and 36 weeks after treatment initiation. A total of 179 patients were randomized to teriflunomide 7  mg  (n=61), teriflunomide 14 mg (n=57), or placebo (n= 61). Baseline demographics were  consistent across treatment groups. The primary endpoint was the average number of unique  active lesions/MRI scan during treatment. The mean number of unique active lesions per brain  MRI scan during the 36-week treatment period was lower in patients treated with teriflunomide 7  mg (1.06) and teriflunomide 14 mg (0.98) as compared to placebo (2.69), the difference  being statistically significant for both (p=0.0234 and p=0.0052,  respectively).
