Indications
BKEMV™ (eculizumab-aeeb) is indicated for the treatment of:
- patients with paroxysmal nocturnal hemoglobinuria (PNH) to reduce hemolysis.
- patients with atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy.
- generalized myasthenia gravis (g... Read More

IMPORTANT SAFETY INFORMATION
WARNING: SERIOUS MENINGOCOCCAL INFECTIONS
Eculizumab products, complement inhibitors, increase the risk of serious infections caused by Neisseria meningitidis. Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.
IMPORTANT SAFETY INFORMATION
WARNING: SERIOUS MENINGOCOCCAL INFECTIONS
Eculizumab products, complement inhibitors, increase the risk of serious infections caused by Neisseria meningitidis. Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early.
- Complete or update vaccination for meningococcal bacteria (for serogroups A, C, W, Y, and B) at least 2 weeks prior to the first dose of BKEMV, unless the risks of delaying therapy with BKEMV outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against meningococcal bacteria in patients receiving a complement inhibitor. See Warnings and Precautions for additional guidance on the management of the risk of serious infections caused by meningococcal bacteria.
- Patients receiving eculizumab products are at increased risk for invasive disease caused by Neisseria meningitidis, even if they develop antibodies following vaccination. Monitor patients for early signs and symptoms of serious meningococcal infections and evaluate immediately if infection is suspected. Because of the risk of serious meningococcal infections, BKEMV is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called BKEMV REMS.

Contraindications:
BKEMV is contraindicated for initiation in patients with unresolved serious Neisseria meningitidis infection.
Other Infections
Use caution when administering BKEMV to patients with any other systemic infection. 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.
Monitoring 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. 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, or appropriate organ-specific supportive measures.
Thrombosis 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.
Infusion-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.
Adverse Reactions
The most frequently reported adverse reactions in:
- the PNH randomized trial (≥10% overall and greater than placebo) are: headache, nasopharyngitis, back pain, and nausea
- the aHUS single arm prospective trials (≥20%) are: headache, diarrhea, hypertension, upper respiratory infection, abdominal pain, vomiting, nasopharyngitis, anemia, cough, peripheral edema, nausea, urinary tract infections, and pyrexia
- the gMG placebo-controlled clinical trial (≥10%) is musculoskeletal pain
Drug Interactions
- Concomitant use of eculizumab products with plasma exchange (PE), plasmapheresis (PP) or fresh frozen plasma infusion (PE/PI) treatment can reduce serum eculizumab products concentrations and requires a supplement dose of BKEMV.
- 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.

INDICATIONS
BKEMV™ (eculizumab-aeeb) is indicated for the treatment:
- patients with paroxysmal nocturnal hemoglobinuria (PNH) to reduce hemolysis.
- patients with atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy.
- generalized myasthenia gravis (gMG) in adult patients who are anti-acetylcholine receptor (AchR) antibody positive.
BKEMV is not indicated for the treatment of patients with Shiga toxin E. coli related hemolytic uremic syndrome (STEC-HUS).
