Warnings
Black Box Warnings
Hepatotoxicity
- Clinically significant and potentially life-threatening liver injury, including acute liver failure requiring transplant, reported
- 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 initiating therapy; monitor ALT levels at least monthly for 6 months after starting therapy
- If drug-induced liver injury is suspected, discontinue treatment and start an accelerated elimination procedure with cholestyramine or charcoal
- Contraindicated in patients with severe hepatic impairment; patients with pre-existing liver disease may be at increased risk of developing elevated serum transaminases during treatment
Embryofetal toxicity
- Use is contraindicated in pregnant women and in females of reproductive potential who are not using effective contraception because of the potential for fetal harm
- Teratogenicity and embryo lethality occurred in animals at plasma teriflunomide exposures lower than that in humans
- Exclude pregnancy before initiating treatment in females of reproductive potential
- Females of reproductive potential should use effective contraception during treatment and during an accelerated drug elimination procedure after treatment
- Stop teriflunomide and use an accelerated drug elimination procedure if patient becomes pregnant
Contraindications
History of hypersensitivity reaction to teriflunomide, leflunomide, or excipients
Severe hepatic impairment
Pregnancy
Current leflunomide treatment
Cautions
Risk of malignancy, particularly lymphoproliferative disorders, is increased with use of some immunosuppressive medications; there is potential for immunosuppression with this drug; no apparent increase in the incidence of malignancies and lymphoproliferative disorders reported in 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 therapy
No clinical data available on efficacy and safety of live vaccinations in patients receiving therapy; vaccination with live vaccines is not recommended; the long half-life of the drug should be considered when contemplating administration of a live vaccine after stopping therapy
May take an average of 8 months to clear drug from plasma; consider accelerated elimination with cholestyramine or activated charcoal
Decreases in white blood cell count and platelet count have been observed; a recent CBC should be available before starting teriflunomide; monitor for signs and symptoms of infection; consider suspending treatment with teriflunomide in case of serious infection; do not start teriflunomide in patients with active infections
Not recommended for patients with serious immunodeficiency; do not initiate treatment in patients with active acute or chronic infections
Peripheral neuropathy, including polyneuropathy and mononeuropathy, have been reported; evaluate patient and consider discontinuing therapy; if a patient taking drug develops symptoms consistent with peripheral neuropathy, such as bilateral numbness or tingling of hands or feet, consider discontinuing therapy and performing accelerated elimination procedure
May cause an increase in renal uric acid clearance and decreases in serum uric acid
Use caution in hyperkalemia
Anaphylaxis and severe allergic reactions reported; signs and symptoms have included dyspnea, urticaria, and angioedema including lips, eyes, throat, and tongue; inform patients of signs and symptoms of anaphylaxis and angioedema
May increase blood pressure; measure blood pressure at treatment initiation and monitor blood pressure during treatment; elevated blood pressure should be appropriately managed during treatment
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 accelerated elimination procedure
Pancreatitis reported; if pancreatitis is suspected, discontinue teriflunomide and start an accelerated elimination procedure
Cases of tuberculosis reported; prior to initiating therapy, screen patients for latent tuberculosis infection with a tuberculin skin test or with a blood test for mycobacterium tuberculosis infection
Hepatotoxicity
- Clinically significant and potentially life-threatening liver injury, including acute liver failure requiring transplant, reported in patients receiving therapy in the postmarketing setting; patients with pre-existing liver disease and patients taking other hepatotoxic drugs may be at increased risk for developing liver injury when taking this drug; clinically significant liver injury can occur at any time during therapy
- Patients with pre-existing acute or chronic liver disease, or those with serum alanine aminotransferase (ALT) greater than two times upper limit of normal (ULN) before initiating treatment, should not normally be treated with this drug
- Obtain serum transaminase and bilirubin levels within 6 months before initiation of therapy; monitor ALT levels at least monthly for six months after starting treatment; consider additional monitoring when therapy administered with other potentially hepatotoxic drugs
- Consider discontinuing therapy if serum transaminase increase (>3x ULN) is confirmed; monitor serum transaminase and bilirubin, 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 suspected to be therapy-induced, discontinue drug and start an accelerated elimination procedure and monitor liver tests weekly until normalized; if drug-induced liver injury is unlikely because some other probable cause found, resumption of therapy may be considered
Accelerated elimination of teriflunomide
- This drug is eliminated slowly from plasma; without accelerated elimination procedure, it takes on average 8 months to reach plasma concentrations < 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 treatment; elimination can be accelerated by either of the following procedures:
- Administration of cholestyramine 8 g q8hr for 11 days; if cholestyramine 8 g TID not well tolerated, cholestyramine 4 g TID 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 need to lower teriflunomide plasma concentration rapidly
- At end of 11 days, both regimens successfully have accelerated teriflunomide elimination, leading to more than 98% decrease in teriflunomide plasma concentrations; use of accelerated elimination procedure may potentially result in return of disease activity if patient had been responding to treatment
Skin reactions
- Cases of serious skin reactions, including cases of Stevens-Johnson syndrome (SJS) and a fatal case of toxic epidermal necrolysis (TEN), reported
- Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity, has occurred with therapy; DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy and/or facial swelling, in association with other organ system involvement, such as hepatitis, nephritis, hematologic abnormalities, myocarditis, or myositis, sometimes resembling an acute viral infection
- Eosinophilia is often present; this disorder is variable in itsexpression, and other organ systems not noted here may be involved; it is important to note that early manifestations of hypersensitivity (eg, fever, lymphadenopathy) may be present even though rash is not evident; if such signs or symptoms are present, the patient should be evaluatedimmediately
- Inform patients of signs and symptoms that may signal a serious skin reaction; instruct patients to discontinue therapy and seek immediate medical care should these signs and symptoms occur
- Unless reaction is clearly not drug-related, discontinue therapy and begin an accelerated elimination procedure immediately; in such cases, patients should not be re-exposed to drug
- Early manifestations of hypersensitivity (eg, fever, lymphadenopathy) may be present even though rash is not evident; if such signs or symptoms are present, the patient should be evaluated immediately
- Discontinue therapy unless an alternative etiology for the signs or symptoms is established, and begin an accelerated elimination procedure immediately; in such cases, patients should not be re-exposed to drug
Bone Marrow Effects / Immunosuppression Potential
- Cases of thrombocytopenia, including rare cases with platelet counts < 50,000/mm3, reported in postmarketing setting; obtain a complete blood cell count (CBC) within 6 months before initiation of treatment; further monitoring should be based on signs and symptoms suggestive of bone marrow suppression
- A 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% observed
- Most reports confounded by concomitant immunosuppressant therapy and/or comorbid illness which, in addition to rheumatoid disease, may predispose patients to infection
Risk of infection
- Patients with active acute or chronic infections should not start treatment until infection(s) is resolved; if patient develops a serious infection consider suspending treatment and using an accelerated elimination procedure; reassess benefits and risks prior to resumption of therapy; instruct patients to report symptoms of infections to a physician
- Therapy not recommended for patients with severe immunodeficiency, bone marrow disease, or severe, uncontrolled infections; medications that have immunosuppression potential may cause patients to be more susceptible to infections, including opportunistic infections
- One fatal case of klebsiella pneumonia sepsis reported in a patient taking this medication (14 mg) for 1.7 years; fatal infections reported in postmarketing setting in patients receiving this drug, especially Pneumocystis jirovecii pneumonia and aspergillosis
- Most 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, cytomegalovirus hepatitis reactivation has been observed
- In clinical tirals in adult patients, cases of tuberculosis observed; prior to initiating treatment, screen patients for latent tuberculosis infection with a tuberculin skin test or with blood test for mycobacterium tuberculosis infection
- This drug has not been studied in patients with a positive tuberculosis screen, and safety in individuals with latent tuberculosis infection is unknown; for patients testing positive in tuberculosis screening, treat by standard medical practice prior to administering therapy
Drug interaction overview
- Teriflunomide is CYP2C8 inhibitor, weak CYP1A2 inducer, organic anion transporter 3 (OAT3) inhibitor; BCRP and organic anion transporting polypeptide B1 and B3 (OATP1B1/1B3) inhibitor
- Coadministration with CYP2C8 substrates (eg, paclitaxel, pioglitazone, repaglinide, rosiglitazone) may increase exposure to the CYP2C8 substrates
- Coadministration with warfarin requires close monitoring of INR because teriflunomide may decrease peak INR by ~25%
- Teriflunomide may increase the systemic exposures of ethinylestradiol and levonorgestrel; consider the type or dose of contraceptives used in combination with teriflunomide
- Coadministration with OAT3 substrates may increase exposure of the OAT3 substrates
- Concomitant use with CYP1A2 substrates and teriflunomide may reduce expose of the CYP1A2 substrates
-
Immunosuppressive or immunomodulating therapies
- Coadministration with antineoplastic or immunosuppressive therapies used for treatment of multiple sclerosis has not been evaluated
- When switching from teriflunomide to another agent with a known potential for hematologic suppression, 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 treatment
Pregnancy & Lactation
Pregnancy
Contraindicated for use in pregnant women and females of reproductive potential not using effective contraception because of potential for fetal harm based on animal data
Exclude pregnancy before initiating treatment in females of reproductive potential; advise females to notify their healthcare provider immediately if pregnancy occurs or is suspected during treatment
Discontinue treatment in female who wish to become pregnantand undergo accelerated elimination procedure to decrease plasma concentration of teriflunomide to less than 0.02 mg/L (0.02 mcg/mL); use effective contraception until is verified that plasma concentrations of teriflunomide are less than 0.02 mg/L (0.02 mcg/mL), which are expected to have minimal embryofetal risk
If patient becomes pregnant during therapy, stop treatment, inform patient of potential risk to fetus, and perform accelerated drug elimination procedure to achieve plasma concentrations of less than 0.02 mg/L (0.02 mcg/mL); refer patient to obstetrician/gynecologist, preferably experienced in reproductive toxicity, for further evaluation and counseling
Pregnancy exposure registry
- Registry monitors pregnancy outcomes in women exposed to therapy during pregnancy; healthcare providers and patients are encouraged to report pregnancies by calling 1-800-745-4447, option 2
Males
- Drug is detected in human semen; animal studies to specifically evaluate 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
- Discontinue therapy in men wishing to father a child 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)
- To minimize any possible risk, men not wishing to father a child and their female partners should use effective contraception
Lactation
Not known whether drug is excreted in human milk; detected in rat milk following a single oral dose; because of potential for adverse reactions in a breastfed infant from therapy, women should not breastfeed during treatment
Consider developmental and health benefits of breastfeeding along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

TERIFLUNOMIDE - ORAL
(TER-i-FLOO-noe-mide)
COMMON BRAND NAME(S): Aubagio
WARNING: Teriflunomide must not be used during pregnancy because it may cause serious harm (such as birth defects, death) in an unborn baby. Women of childbearing age must have a negative pregnancy test before starting this medication. Men and women must use reliable forms of birth control (such as condoms, birth control pills) while taking teriflunomide and for as long as directed by your doctor to prevent pregnancy. After stopping treatment with teriflunomide, your doctor may prescribe a different drug to help speed up the removal of teriflunomide from your body. If you become pregnant or think you may be pregnant or cause a pregnancy, tell your doctor right away. (See also How to Use and Precautions sections.)This drug may rarely cause serious (possibly fatal) liver disease. Careful monitoring by your doctor may help decrease your risk. Your doctor will perform liver function tests before you start treatment and once a month for at least the first 6 months of treatment. Tell your doctor right away if you notice nausea/vomiting that doesn't stop, dark urine, loss of appetite, stomach/abdominal pain, or yellowing eyes/skin.
USES: This medication is used by adults to treat multiple sclerosis-MS. It is not a cure for MS but is thought to work by decreasing certain immune system cells (lymphocytes) which can attack the nerves in your brain and spinal cord. This helps decrease the number of flare-ups (relapses) and may help slow down physical problems caused by MS.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start taking teriflunomide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually once daily. The dosage is based on your medical condition and response to treatment.Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.After treatment is stopped, your doctor may prescribe a different drug (cholestyramine or activated charcoal powder) to help speed up the removal of teriflunomide from your body. This may be used if you have severe side effects, or if you are a woman of childbearing age, or a man planning to father a child. Otherwise, teriflunomide can stay in your body for as long as 2 years after stopping treatment. Consult your doctor or pharmacist for more details.Tell your doctor if your symptoms do not improve or if they worsen.
SIDE EFFECTS: See also Warning section.Diarrhea, nausea, or tingling/burning/numbness/prickling feelings in your skin may occur.
