Eculizumab-Aeeb (1 brand name, 1 dosage form, 1 route)
Available dosage forms: INJECTABLE.
Routes of administration: INJECTION.
Brand Names
- BKEMV
Boxed Warning
Eculizumab products, complement inhibitors, increase the risk of serious infections caused by Neisseria meningitidis [see Warnings and Precautions (5.1)]. 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 (5.1) 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 [see Warnings and Precautions (5.2) ].
Contraindications
BKEMV is contraindicated for initiation in patients with unresolved serious Neisseria meningitidis infection [see Warnings and Precautions (5.1) ].
Adverse Reactions
The following serious adverse reactions are discussed in greater detail in other sections of the labeling: Serious Meningococcal Infections [see Warnings and Precautions (5.1) ] Other Infections [see Warnings and Precautions (5.3) ] Monitoring Disease Manifestations after BKEMV Discontinuation [see Warnings and Precautions (5.4) ] Thrombosis Prevention and Management [see Warnings and Precautions (5.5) ] Infusion-Related Reactions [see Warnings and Precautions (5.6) ]
Mechanism of Action
Eculizumab-aeeb, the active ingredient in BKEMV, is a monoclonal antibody that specifically binds to the complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a and C5b and preventing the generation of the terminal complement complex C5b-9. Eculizumab products inhibit terminal complement-mediated intravascular hemolysis in PNH patients and complement-mediated thrombotic microangiopathy (TMA) in patients with aHUS. The precise mechanism by which eculizumab exerts its therapeutic effect in gMG patients is unknown, but is presumed to involve reduction of terminal complement complex C5b-9 deposition at the neuromuscular junction.
