The admixture must not be heated in a microwave or with any heat source other than ambient air temperature. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. 2.7 Administration Only administer as an intravenous infusion. Do not administer as an intravenous push or bolus injection. Administer the EPYSQLI admixture by intravenous infusion over 35 minutes in adults and 1 to 4 hours in pediatric patients via gravity feed, a syringe-type pump, or an infusion pump. If an adverse reaction occurs during the administration of EPYSQLI, the infusion may be slowed or stopped at the discretion of the physician. If the infusion is slowed, the total infusion time should not exceed two hours in adults. Monitor the patient for at least one hour following completion of the infusion for signs or symptoms of an infusion-related reaction.

WARNINGS AND PRECAUTIONS Use caution when administering EPYSQLI 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 ) 5.1 Serious 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 EPYSQLI 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 EPYSQLI, according to current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations, considering the duration of therapy with EPYSQLI. 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 EPYSQLI 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 EPYSQLI, 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 EPYSQLI in patients who are undergoing treatment for serious meningococcal infection, depending on the risks of interrupting treatment in the disease being treated. EPYSQLI is available only through a restricted program under a REMS [see Warnings and Precautions ( 5.2 )] . 5.2 EPYSQLI REMS EPYSQLI is available only through a restricted program under a REMS called EPYSQLI REMS, because of the risk of serious meningococcal infections [see Warnings and Precautions ( 5.1 )] . Notable requirements of the EPYSQLI 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 two weeks prior to the first dose of EPYSQLI. 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 EPYSQLI. Healthcare settings and pharmacies that dispense EPYSQLI 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 EPYSQLI. Further information is available at www.EPYSQLIREMS.com or 1-866-318-0342. 5.3 Other 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. 5.4 Monitoring Disease Manifestations after EPYSQLI Discontinuation Treatment Discontinuation for PNH Monitor patients after discontinuing EPYSQLI for at least 8 weeks to detect hemolysis. Treatment Discontinuation for aHUS After discontinuing EPYSQLI, 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 EPYSQLI treatment; an increase in serum creatinine by 25% or more compared to baseline or nadir during EPYSQLI treatment; or, an increase in serum LDH by 25% or more over baseline or nadir during EPYSQLI treatment. If TMA complications occur after EPYSQLI discontinuation, consider reinstitution of EPYSQLI treatment, plasma therapy [plasmapheresis, plasma exchange, or fresh frozen plasma infusion (PE/PI)], or appropriate organ-specific supportive measures. 5.5 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. 5.6 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 EPYSQLI infusion and institute appropriate supportive measures if signs of cardiovascular instability or respiratory compromise occur.

CONTRAINDICATIONS EPYSQLI is contraindicated for initiation in patients with unresolved serious Neisseria meningitidis infection [ see Warnings and Precautions ( 5.1 ) ]. EPYSQLI is contraindicated for initiation in patients with unresolved serious Neisseria meningitidis infection. ( 4 )

Mechanism of Action Eculizumab-aagh, the active ingredient in EPYSQLI, 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.
