Warnings and precautions
Use caution when administering BKEMV to patients with any other systemic infection. ( 5.3 ) Infusion-Related Reactions: Monitor patients during infusion, interrupt for reactions, and institute appropriate supportive measures. ( 5.6 )
5.1Serious Meningococcal Infections
Eculizumab products, complement inhibitors, increase a patient's susceptibility to serious, life-threatening, or fatal infections caused by meningococcal bacteria (septicemia and/or meningitis) in any serogroup, including non-groupable strains. Life-threatening and fatal meningococcal infections have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. The initiation of BKEMV treatment is contraindicated in patients with unresolved serious Neisseria meningitidis infection.
Complete or update meningococcal vaccination (for serogroups A, C, W, Y and B) at least 2 weeks prior to administration of the first dose of BKEMV, according to current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with BKEMV. Note that ACIP recommends an administration schedule in patients receiving complement inhibitors that differs from the administration schedule in the vaccine prescribing information.
If urgent BKEMV therapy is indicated in a patient who is not up to date with meningococcal vaccines according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer meningococcal vaccines as soon as possible. Various durations and regimens of antibacterial drug prophylaxis have been considered, but the optimal durations and drug regimens for prophylaxis and their efficacy have not been studied in unvaccinated or vaccinated patients receiving complement inhibitors, including eculizumab products.
The benefits and risks of treatment with BKEMV, as well as the benefits and risks of antibacterial drug prophylaxis in unvaccinated or vaccinated patients, must be considered against the known risks for serious infections caused by Neisseria meningitidis . Vaccination does not eliminate the risk of serious meningococcal infections, despite development of antibodies following vaccination. Closely monitor patients for early signs and symptoms of meningococcal infection and evaluate patients immediately if infection is suspected.
Inform patients of these signs and symptoms and instruct patients to seek immediate medical care if these signs and symptoms occur. Promptly treat known infections. Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early. Consider interruption of BKEMV in patients who are undergoing treatment for serious meningococcal infection, depending on the risks of interrupting treatment in the disease being treated.
BKEMV is available only through a restricted program under a REMS [see Warnings and Precautions (5.2) ] .
5.2BKEMV REMS
BKEMV is available only through a restricted program under a REMS called BKEMV REMS, because of the risk of serious meningococcal infections [see Warnings and Precautions (5.1) ] . Notable requirements of the BKEMV REMS include the following: Prescribers must enroll in the REMS. Prescribers must counsel patients about the risk of serious meningococcal infection. Prescribers must provide the patients with the REMS educational materials.
Prescribers must assess patient vaccination status for meningococcal vaccines (against serogroups A, C, W, Y and B) and vaccinate if needed according to current ACIP recommendations 2 weeks prior to the first dose of BKEMV. Prescribers must provide a prescription for antibacterial drug prophylaxis if treatment must be started urgently and the patient is not up to date with meningococcal vaccines according to current ACIP recommendations at least two weeks prior to the first dose of BKEMV.
Healthcare settings and pharmacies that dispense BKEMV must be certified in the REMS and must verify prescribers are certified. Patients must receive counseling from the prescriber about the need to receive meningococcal vaccines per ACIP recommendations, the need to take antibiotics as directed by the prescriber, and the signs and symptoms of meningococcal infection. Patients must be instructed to carry the Patient Safety Card with them at all times during and for 3 months following treatment with BKEMV.

5.3Other Infections
Serious infections with Neisseria species (other than Neisseria meningitidis ), including disseminated gonococcal infections, have been reported. Eculizumab products block terminal complement activation; therefore, patients may have increased susceptibility to infections, especially with encapsulated bacteria, such as infections with Neisseria meningitidis but also Streptococcus pneumoniae , Haemophilus influenzae , and to a lesser extent, Neisseria gonorrhoeae .
Additionally, Aspergillus infections have occurred in immunocompromised and neutropenic patients. Children treated with eculizumab products may be at increased risk of developing serious infections due to Streptococcus pneumoniae and Haemophilus influenzae type b (Hib). Administer vaccinations for the prevention of Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) infections according to ACIP recommendations.
Patients receiving eculizumab products are at increased risk for infections due to these organisms, even if they develop antibodies following vaccination.
5.4Monitoring Disease Manifestations after
BKEMV Discontinuation Treatment Discontinuation for PNH Monitor patients after discontinuing BKEMV for at least 8 weeks to detect hemolysis. Treatment Discontinuation for aHUS After discontinuing BKEMV, monitor patients with aHUS for signs and symptoms of thrombotic microangiopathy (TMA) complications for at least 12 weeks. In aHUS clinical trials, 18 patients (5 in the prospective studies) discontinued eculizumab treatment.
TMA complications occurred following a missed dose in 5 patients, and eculizumab was reinitiated in 4 of these 5 patients. Clinical signs and symptoms of TMA include changes in mental status, seizures, angina, dyspnea, or thrombosis. In addition, the following changes in laboratory parameters may identify a TMA complication: occurrence of two, or repeated measurement of any one of the following: a decrease in platelet count by 25% or more compared to baseline or the peak platelet count during BKEMV treatment; an increase in serum creatinine by 25% or more compared to baseline or nadir during BKEMV treatment; or, an increase in serum LDH by 25% or more over baseline or nadir during BKEMV treatment.
If TMA complications occur after BKEMV discontinuation, consider reinstitution of BKEMV treatment, plasma therapy [plasmapheresis, plasma exchange, or fresh frozen plasma infusion (PE/PI)], or appropriate organ-specific supportive measures.
5.5Thrombosis Prevention and Management
The effect of withdrawal of anticoagulant therapy during eculizumab products treatment has not been established. Therefore, treatment with eculizumab products should not alter anticoagulant management.
5.6Infusion-Related Reactions Administration
of eculizumab products may result in infusion-related reactions, including anaphylaxis or other hypersensitivity reactions. In clinical trials, no patients experienced an infusion-related reaction which required discontinuation of eculizumab. Interrupt BKEMV infusion and institute appropriate supportive measures if signs of cardiovascular instability or respiratory compromise occur.
Interactions
7.1Plasmapheresis, Plasma Exchange, Fresh Frozen Plasma Infusion or IVIg
Concomitant use of eculizumab products with plasma exchange (PE), plasmapheresis (PP), fresh frozen plasma infusion (PE/PI), or in patients with gMG on concomitant IVIg treatment can reduce serum eculizumab product concentrations and requires a supplemental dose of BKEMV [see Dosage and Administration (2.5) ] .
7.2Neonatal Fc Receptor Blockers
Concomitant use of eculizumab products with neonatal Fc receptor (FcRn) blockers may lower systemic exposures and reduce effectiveness of eculizumab products. Closely monitor for reduced effectiveness of BKEMV.
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
Limited data on outcomes of pregnancies that have occurred following eculizumab use in pregnant women have not identified a concern for specific adverse developmental outcomes ( see Data ). There are risks to the mother and fetus associated with untreated paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS) in pregnancy ( see Clinical Considerations ). Animal studies using a mouse analogue of the eculizumab molecule (murine anti-C5 antibody) showed increased rates of developmental abnormalities and an increased rate of dead and moribund offspring at doses 2-8 times the human dose ( see Data ) .
The estimated background risk of major birth defects and miscarriage for the indicated populations 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 defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease-associated maternal and/or fetal/neonatal risk PNH in pregnancy is associated with adverse maternal outcomes, including worsening cytopenias, thrombotic events, infections, bleeding, miscarriages and increased maternal mortality, and adverse fetal outcomes, including fetal death and premature delivery. aHUS in pregnancy is associated with adverse maternal outcomes, including pre-eclampsia and preterm delivery, and adverse fetal/neonatal outcomes, including intrauterine growth restriction (IUGR), fetal death and low birth weight.
Data Human Data A pooled analysis of prospectively (50.3%) and retrospectively (49.7%) collected data in more than 300 pregnant women with live births following exposure to eculizumab have not suggested safety concerns. However, these data cannot definitively exclude any drug-associated risk during pregnancy, because of the limited sample size. Animal Data Animal reproduction studies were conducted in mice using doses of a murine anti-C5 antibody that approximated 2-4 times (low dose) and 4-8 times (high dose) the recommended human eculizumab dose, based on a body weight comparison.
When animal exposure to the antibody occurred in the time period from before mating until early gestation, no decrease in fertility or reproductive performance was observed. When maternal exposure to the antibody occurred during organogenesis, two cases of retinal dysplasia and one case of umbilical hernia were observed among 230 offspring born to mothers exposed to the higher antibody dose; however, the exposure did not increase fetal loss or neonatal death.
When maternal exposure to the antibody occurred in the time period from implantation through weaning, a higher number of male offspring became moribund or died (1/25 controls, 2/25 low dose group, 5/25 high dose group). Surviving offspring had normal development and reproductive function.

6.1Clinical Trial 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 practice. Meningococcal infections are the most important adverse reactions experienced by patients receiving eculizumab. In PNH clinical studies, two patients experienced meningococcal sepsis.
Both patients had previously received a meningococcal vaccine. In clinical studies among patients without PNH, meningococcal meningitis occurred in one unvaccinated patient. Meningococcal sepsis occurred in one previously vaccinated patient enrolled in the retrospective aHUS study during the post-study follow-up period [ see Warnings and Precautions (5.1) ]. PNH The data described below reflect exposure to eculizumab in 196 adult patients with PNH, age 18-85, of whom 55% were female.
All had signs or symptoms of intravascular hemolysis. Eculizumab was studied in a placebo-controlled clinical study (PNH Study 1, in which 43 patients received eculizumab and 44, placebo); a single arm clinical study (PNH Study 2); and a long-term extension study (E05-001). One hundred and eighty two patients were exposed for greater than one year. All patients received the recommended eculizumab dose regimen. Table 5 summarizes the adverse reactions that occurred at a numerically higher rate in the eculizumab group than the placebo group and at a rate of 5% or more among patients treated with eculizumab.
Table 5: Adverse Reactions Reported in 5% or More of Eculizumab Treated Patients with PNH and Greater than Placebo in the Controlled Clinical Study Reaction Eculizumab (N = 43) N (%) Placebo (N = 44) N (%) Headache 19 (44) 12 (27) Nasopharyngitis 10 (23) 8 (18) Back pain 8 (19) 4 (9) Nausea 7 (16) 5 (11) Fatigue 5 (12) 1 (2) Cough 5 (12) 4 (9) Herpes simplex infections 3 (7) 0 Sinusitis 3 (7) 0 Respiratory tract infection 3 (7) 1 (2) Constipation 3 (7) 2 (5) Myalgia 3 (7) 1 (2) Pain in extremity 3 (7) 1 (2) Influenza-like illness 2 (5) 1 (2) In the placebo-controlled clinical study, serious adverse reactions occurred among 4 (9%) patients receiving eculizumab and 9 (21%) patients receiving placebo.
The serious reactions included infections and progression of PNH. No deaths occurred in the study and no patients receiving eculizumab experienced a thrombotic event; one thrombotic event occurred in a patient receiving placebo. Among 193 patients with PNH treated with eculizumab in the single arm, clinical study or the follow-up study, the adverse reactions were similar to those reported in the placebo-controlled clinical study.
Serious adverse reactions occurred among 16% of the patients in these studies. The most common serious adverse reactions were: viral infection (2%), headache (2%), anemia (2%), and pyrexia (2%). aHUS The safety of eculizumab therapy in patients with aHUS was evaluated in four prospective, single-arm studies, three in adult and adolescent patients (Studies C08-002A/B, C08-003A/B, and C10-004), one in pediatric and adolescent patients (Study C10-003), and one retrospective study (Study C09-001r).
The data described below were derived from 78 adult and adolescent patients with aHUS in Studies C08-002A/B, C08-003A/B and C10-004. All patients received the recommended dosage of eculizumab. Median exposure was 67 weeks (range: 2-145 weeks). Table 6 summarizes all adverse events reported in at least 10% of patients in Studies C08-002A/B, C08-003A/B and C10-004 combined.

The most commonly reported SAEs were infections (24%), hypertension (5%), chronic renal failure (5%), and renal impairment (5%). Five patients discontinued eculizumab due to adverse events; three due to worsening renal function, one due to new diagnosis of Systemic Lupus Erythematosus, and one due to meningococcal meningitis. Study C10-003 included 22 pediatric and adolescent patients, of which 18 patients were less than 12 years of age.
All patients received the recommended dosage of eculizumab. Median exposure was 44 weeks (range: 1 dose-87 weeks).
