Postmarketing Reports
Fatal anaphylaxis
Warnings
Contraindications
Anaphylaxis to belimumab
Cautions
Serious and sometimes fatal infections reported in patients receiving immunosuppressive agents; consider risk and benefit before initiating treatment in patients with severe or chronic infections; consider interrupting therapy in patients who develop a new infection during therapy and monitor patients closely
Impact on development of malignancies is unknown; as with other immunomodulating agents, mechanism of action of belimumab could increase the risk for developing malignancies; consider individual benefit-risk in patients with known risk factors for development or reoccurrence of malignancy prior to prescribing this medication; in patients who develop malignancies, consider risk and benefit of continued treatment
Cases of JC virus-associated PML resulting in neurological deficits, including fatal cases, reported in patients with SLE receiving immunosuppressants; risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function; consider diagnosis of PML in any patient presenting with new-onset or deteriorating neurological signs and symptoms and consult with a neurologist or other appropriate specialist as clinically indicated; in patients with confirmed PML, consider stopping therapy
Hypersensitivity reactions
- Acute hypersensitivity reactions, including anaphylaxis and death, reported; events generally occurred within hours of infusion; however, they may occur later; non-acute hypersensitivity reactions including rash, nausea, fatigue, myalgia, headache, and facial edema reported and typically occurred up to a week following the most recent infusion
- Hypersensitivity, including serious reactions, has occurred in patients who have previously tolerated infusions of the drug; limited data suggest that patients with a history of multiple drug allergies or significant hypersensitivity may be at increased risk
- Therapy should be administered by healthcare providers prepared to manage anaphylaxis; in the event of a serious reaction, discontinue treatment immediately and administer appropriate medical therapy; monitor patients during infusion and for an appropriate period of time after intravenous administration of the drug
- Consider administering premedication as prophylaxis prior to intravenous dosing; Inform patients receiving the drug of the signs and symptoms of hypersensitivity reactions and instruct them to seek immediate medical care should a reaction occur
Infusion reactions
- Serious infusion reactions (excluding hypersensitivity reactions) reported, including bradycardia, myalgia, headache, rash, urticaria, and hypotension; most common reactions included headache, nausea, and skin reactions; consider administering premedication as prophylaxis prior to intravenous dosing
- For intravenous use, therapy should be administered by healthcare providers prepared to manage infusion reactions; infusion rate may be slowed or interrupted if patient develops a reaction; monitor during and for an appropriate period of time after infusion
- Healthcare providers should be aware of risk of hypersensitivity reactions, which may present as infusion reactions, and monitor patients closely; instruct patients to seek immediate medical care should a reaction occur
Depression and suicidality
- In clinical trials, psychiatric events were associated with IV administration in SLE patients
- Before treatment, assess risk of depression and suicide considering the patient’s medical history and current psychiatric status
- Continue to monitor during treatment
- Instruct patients to contact healthcare provider if new or worsening depression arises, suicidal thoughts or behavior, or other mood changes; assess risk and benefit of continued therapy for patients who develop such symptoms
- Consider risk and benefit of continued treatment for patients who develop symptoms of depression or suicidality
Drug interaction overview
-
Immunizations
- Do not administer live vaccines 30 days before or concurrently with belimumab
- May decrease response to immunizations
-
Other biologic therapies
- Not studied in combination with other biologic therapies (eg, B-cell targeted therapies) and therefore not recommended
Pregnancy & Lactation
Pregnancy
Healthcare professionals are encouraged to register patients by calling the pregnancy registry: at 1- (877) 681-6296
Data are insufficient to determine whether there is a drug-associated risk for major birth defects or miscarriage
There are risks to the mother and fetus associated with SLE, including worsening of the underlying disease, premature birth, spontaneous abortion, and intrauterine growth restriction
Clinical considerations
- Maternal lupus nephritis increases the risk of hypertension and preeclampsia/eclampsia
- Passage of maternal antiphospholipid antibodies across the placenta may result in adverse neonatal outcomes, including neonatal lupus and congenital heart block
- Monoclonal antibodies, such as belimumab, are actively transported across the placenta during the third trimester of pregnancy and may affect immune response in the in utero-exposed infant
- Use during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus
Contraception
- Following an assessment of benefit versus risk, if prevention of pregnancy is warranted, females of reproductive potential should use effective contraception during treatment and for at least 4 months after the final treatment
Lactation
Passage of maternal antiphospholipid antibodies across the placenta may result in adverse neonatal outcomes, including neonatal lupus and congenital heart block
Monoclonal antibodies, such as belimumab, are actively transported across the placenta during the third trimester of pregnancy and may affect immune response in the in utero-exposed infant
Use during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus
Because maternal antibodies are excreted in human breast milk, a decision should be made whether to discontinue breastfeeding or to discontinue the drug, taking into account the importance of breastfeeding to the infant and the importance of the drug to the mother
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
Mechanism of Action
Inhibits the biological activity of B-lymphocyte stimulator (BLyS); BLyS is a naturally occurring protein required for survival and development of B-lymphocyte cells into mature plasma B cells that produce antibodies
In autoimmune diseases, elevated BLyS levels are thought to contribute to production of autoantibodies
Belimumab specifically recognizes and binds to BLyS, inhibits BLyS’s stimulation of B-cell development, and finally, restores the potential for autoantibody-producing B cells to undergo the normal process of apoptosis (programmed cell death)

BELIMUMAB - INJECTION
(be-LIM-ue-mab)
COMMON BRAND NAME(S): Benlysta
USES: This medication is used with other medications to treat certain types of lupus. Belimumab belongs to a class of drugs known as monoclonal antibodies. It works by decreasing the effect of a certain protein that is increased in people with active lupus. This may help decrease some of the symptoms of lupus.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using belimumab and each time you get a treatment. Discuss the risks and benefits of belimumab treatment. If you have any questions, ask your doctor or pharmacist.This medication is given by injection into a vein by a health care professional. It should be injected slowly over 1 hour. The first 3 doses are given every 2 weeks. After the third dose, it is usually given every 4 weeks, or as directed by your doctor. The dosage is based on your weight.Your doctor may prescribe other medications for you to take before the start of your treatment to help prevent serious side effects.This medication may cause very serious reactions during or after treatment. These reactions occur more often during the first and second treatments. Your doctor will monitor you closely. If you have a reaction, your treatment will be temporarily stopped. Tell your doctor or nurse right away if any of these effects occur: headache, slow heartbeat, muscle pain, dizziness/fainting, nausea, or rash/itching.Use this medication regularly to get the most benefit from it. It may help to mark your calendar with a reminder.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: See also How to Use section.Nausea, diarrhea, or trouble sleeping may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as new/worsening depression, thoughts of suicide), signs of cancer (such as fever, night sweats, unusual tiredness, unexplained weight loss, swollen glands, unusual lumps/growths).This medication can lower your body's ability to fight an infection. You may be more likely to get serious infections such as pneumonia, urinary tract infection, and skin infections. It may also be harder to fight an infection you already have. Tell your doctor right away if you develop signs of a serious infection while using this drug, such as: fever, chills, sore throat, cough, pain or burning with urination, urinating often, bloody diarrhea, coughing up mucus.Belimumab may increase your risk of getting a rare but very serious (sometimes fatal) brain infection (progressive multifocal leukoencephalopathy-PML). Get medical help right away if you develop any signs of PML, including: confusion, memory loss, loss of balance, difficulty talking/walking, vision changes.Get medical help right away if you have any serious side effects, including: heart problems (such as chest/jaw/left arm pain, shortness of breath, unusual sweating, dizziness).A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.
