Dosage and administration
See Full Prescribing Information for instructions on dosage, preparation, and administration. ( 2.1 , 2.2 , 2.3 , 2.4 , 2.5 ) Dilute ULTOMIRIS before use. ( 2.5 ) Only administer as an intravenous infusion through a 0.2 or 0.22 micron filter. ( 2.5 ) 2.1 Important Dosage Information ULTOMIRIS is intended to be administered only as an intravenous infusion in adult or pediatric patients one month of age and older. 2.2 Recommended Vaccination and Prophylaxis for Meningococcal Infection Vaccinate patients against meningococcal infection (serogroups A, C, W, Y and B) according to current ACIP recommendations at least 2 weeks prior to initiation of ULTOMIRIS [see Warnings and Precautions (5.1) ] . If urgent ULTOMIRIS 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 these vaccines as soon as possible. Healthcare providers who prescribe ULTOMIRIS must enroll in the ULTOMIRIS and SOLIRIS REMS [see Warnings and Precautions (5.2) ] . 2.3 Recommended Dosage for Intravenous Administration in Adult and Pediatric Patients with PNH or aHUS, and in Adult Patients with gMG or NMOSD The recommended intravenous (IV) ULTOMIRIS loading and maintenance dosing in adult and pediatric patients, one month of age or older weighing 5 kg or greater, with PNH or aHUS, or in adult patients with gMG or NMOSD weighing 40 kg or greater, is based on the patient's body weight, as shown in Table 1, with maintenance doses administered every 4 or 8 weeks, starting 2 weeks after loading dose. The IV dosing schedule is allowed to occasionally vary within 7 days of the scheduled infusion day (except for the first maintenance dose of ULTOMIRIS); but subsequent doses should be administered according to the original schedule. Following a missed IV ULTOMIRIS dose, the patient should contact their health care provider immediately. Table 1: IV Administration of ULTOMIRIS Weight-Based Dosing Regimen – PNH, aHUS, gMG, or NMOSD See Table 4 and Table 5 for selection of the proper total volume and maximum infusion rate [see Dosage and Administration (2.5) ] Indications Body Weight Range (kg) Loading Dose (mg) See Table 2 for ULTOMIRIS treatment initiation instruction and timing of loading dose and maintenance dose Maintenance Dose (mg) and Dosing Interval PNH or aHUS 5 to less than 10 600 300 Every 4 weeks 10 to less than 20 600 600 20 to less than 30 900 2,100 Every 8 weeks 30 to less than 40 1,200 2,700 PNH, aHUS, gMG, or NMOSD 40 to less than 60 2,400 3,000 Every 8 weeks 60 to less than 100 2,700 3,300 100 or greater 3,000 3,600 Refer to Table 2 for treatment initiation instructions in patients who are complement inhibitor treatment-naïve or switching treatment from eculizumab.

ULTOMIRIS vials are for intravenous administration by a healthcare provider and are intended for intravenous administration only. Dilute before use. Use aseptic technique to prepare ULTOMIRIS as follows: 1. The number of vials to be diluted is determined based on the individual patient's weight and the prescribed dose [see Dosage and Administration (2.3) ] . 2. Prior to dilution, visually inspect the solution in the vials; the solution should be free of any particulate matter or precipitation. Do not use if there is evidence of particulate matter or precipitation. 3. Withdraw the calculated volume of ULTOMIRIS from the appropriate number of vials and dilute in an infusion bag using 0.9% Sodium Chloride Injection, USP to a final concentration of 50 mg/mL. The product should be mixed gently. Do not shake. Protect from light. Do not freeze. Refer to Table 4 (loading doses) , Table 5 (maintenance doses) , and Table 6 (supplemental doses) for IV preparation and minimum infusion duration. 4. Administer the prepared solution immediately following preparation. 5. If the diluted ULTOMIRIS infusion solution is not used immediately, storage under refrigeration at 2°C - 8°C (36°F - 46°F) must not exceed 24 hours taking into account the expected infusion time. Once removed from refrigeration, administer the diluted ULTOMIRIS infusion solution within 4 hours. Intravenous Administration of ULTOMIRIS (Healthcare Providers) Only administer as an intravenous infusion through a 0.2 or 0.22 micron filter. Dilute ULTOMIRIS to a final concentration of 50 mg/mL.

Warnings and precautions
Other Infections: Use caution when administering ULTOMIRIS to patients with any other systemic infection. ( 5.3 ) Infusion-Related Reactions: Monitor during infusion, interrupt for reactions, and institute appropriate supportive measures. ( 5.6 ) 5.1 Serious Meningococcal Infections ULTOMIRIS, a complement inhibitor, increases 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 ULTOMIRIS 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 ULTOMIRIS, according to current ACIP recommendations for patients receiving a complement inhibitor. Revaccinate patients in accordance with ACIP recommendations considering the duration of ULTOMIRIS therapy. 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 ULTOMIRIS 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 ULTOMIRIS. The benefits and risks of treatment with ULTOMIRIS, 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 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 ULTOMIRIS in patients who are undergoing treatment for serious meningococcal infection, depending on the risks of interrupting treatment in the disease being treated. ULTOMIRIS is available only through a restricted program under a REMS [see Warnings and Precautions (5.2) ] . 5.2 ULTOMIRIS and SOLIRIS REMS ULTOMIRIS is available only through a restricted program under a REMS called ULTOMIRIS and SOLIRIS REMS, because of the risk of serious meningococcal infections [see Warnings and Precautions (5.1) ]. Notable requirements of the ULTOMIRIS and SOLIRIS 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 ULTOMIRIS. 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 ULTOMIRIS. Healthcare settings and pharmacies that dispense ULTOMIRIS 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 8 months following treatment with ULTOMIRIS. Further information is available at www.UltSolREMS.com or 1-888-765-4747. 5.3 Other Infections Serious infections with Neisseria species (other than Neisseria meningitidis ), including disseminated gonococcal infections, have been reported. ULTOMIRIS blocks terminal complement activation; therefore, patients may have increased susceptibility to infections, especially with encapsulated bacteria, such as infections caused by Neisseria meningitidis but also Streptococcus pneumoniae , Haemophilus influenzae , and to a lesser extent, Neisseria gonorrhoeae . Children treated with ULTOMIRIS 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 ULTOMIRIS are at increased risk for infections due to these organisms, even if they develop antibodies following vaccination.
Side effects
The following clinically significant 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) ] Infusion-Related Reactions [see Warnings and Precautions (5.6) ] Most common adverse reactions in patients with PNH (incidence ≥ 10%) were upper respiratory tract infection and headache. ( 6.1 ) Most common adverse reactions in patients with aHUS (incidence ≥ 20%) were upper respiratory tract infection, diarrhea, nausea, vomiting, headache, hypertension, and pyrexia. ( 6.1 ) Most common adverse reactions in adult patients with gMG (incidence ≥ 10%) were diarrhea and upper respiratory tract infection. ( 6.1 ) Most common adverse reactions in adult patients with NMOSD (incidence ≥ 10%) were COVID-19, headache, back pain, arthralgia, and urinary tract infection. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Alexion Pharmaceuticals, Inc. at 1-844-259-6783 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical 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. Paroxysmal Nocturnal Hemoglobinuria (PNH) Adult Population with PNH Treated with ULTOMIRIS The data described below reflect exposure of 441 adult patients with PNH in Phase 3 studies who received ULTOMIRIS (n = 222) or eculizumab (n = 219) at the recommended dosing regimens with median treatment duration of 6 months for ULTOMIRIS and 6 months for eculizumab. The most frequent adverse reactions (≥ 10%) with ULTOMIRIS were upper respiratory tract infection and headache. Table 7 describes adverse reactions that occurred at a rate of 5% or more among patients treated with ULTOMIRIS in PNH studies. Serious adverse reactions were reported in 15 (6.8%) patients with PNH receiving ULTOMIRIS. The serious adverse reactions in patients treated with ULTOMIRIS included hyperthermia and pyrexia. No serious adverse reaction was reported in more than 1 patient treated with ULTOMIRIS. One fatal case of sepsis was identified in a patient treated with ULTOMIRIS.

Pediatric Population with PNH Treated with ULTOMIRIS In pediatric patients with PNH (aged 9 to 17 years old) included in the pediatric PNH Phase 3 study, the safety profile appeared similar to that observed in adult patients with PNH and in pediatric and adult patients with aHUS. The most common adverse reactions (> 20%) were upper respiratory tract infection, anemia, abdominal pain, and headache. Table 8 describes the adverse reactions that occurred at a rate of 10% or more among pediatric patients treated with ULTOMIRIS in Study ALXN1210-PNH-304.

The most frequent adverse reactions reported in ≥ 20% of patients treated with ULTOMIRIS were upper respiratory tract infection, diarrhea, nausea, vomiting, headache, hypertension, and pyrexia. Table 9, Table 10 and Table 11 describe adverse reactions that occurred at a rate of 10% or more among patients treated with ULTOMIRIS in aHUS studies. Serious adverse reactions were reported in 42 (57%) patients with aHUS receiving ULTOMIRIS. The most frequent serious adverse reactions reported in more than 2 patients (2.7%) treated with ULTOMIRIS were hypertension, pneumonia, and abdominal pain. Four patients died during the ALXN1210-aHUS-311 study. The cause of death was sepsis in 2 patients and intracranial hemorrhage in 1 patient. The fourth patient, who was excluded from the trial after a diagnosis of STEC-HUS, died due to pretreatment cerebral arterial thrombosis.
Drug interactions
Plasma Exchange, Plasmapheresis, or Intravenous Immunoglobulins: concomitant use requires supplemental dose of ULTOMIRIS. ( 7.1 ) Neonatal Fc Receptor Blockers (FcRn): Closely monitor for reduced effectiveness of ULTOMIRIS. ( 7.2 ) 7.1 Plasma Exchange, Plasmapheresis, and Intravenous Immunoglobulins Concomitant use of ULTOMIRIS with plasma exchange (PE), plasmapheresis (PP), or intravenous immunoglobulin (IVIg) treatment can reduce serum ravulizumab concentrations and requires a supplemental dose of ULTOMIRIS [see Dosage and Administration (2.5) ]. 7.2 Neonatal Fc Receptor Blockers Concomitant use of ULTOMIRIS with neonatal Fc receptor (FcRn) blockers (e.g., efgartigimod) may lower systemic exposures and reduce effectiveness of ULTOMIRIS. Closely monitor for reduced effectiveness of ULTOMIRIS.
Use in specific populations
8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ULTOMIRIS during pregnancy. Healthcare providers and patients may call 1-833-793-0563 or go to www.UltomirisPregnancyStudy.com to enroll in or to obtain information about the registry. Risk Summary There are no available data on ULTOMIRIS use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with untreated PNH and aHUS in pregnancy (see Clinical Considerations ) . Animal studies using a mouse analogue of the ravulizumab-cwvz molecule (murine anti-mouse complement component 5 [C5] antibody) showed increased rates of developmental abnormalities and an increased rate of dead and moribund offspring at doses 0.8-2.2 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 defects 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. In pregnancy, aHUS is associated with adverse maternal outcomes, including preeclampsia and preterm delivery, and adverse fetal/neonatal outcomes, including intrauterine growth restriction (IUGR), fetal death and low birth weight. Data Animal Data Animal reproduction studies were conducted in mice using doses of a murine anti-C5 antibody that approximated 1-2.2 times (loading dose) and 0.8-1.8 times (maintenance dose) the recommended human ULTOMIRIS 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, 2 cases of retinal dysplasia and 1 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. Human IgG are known to cross the human placental barrier, and thus ULTOMIRIS may potentially cause terminal complement inhibition in fetal circulation. 8.2 Lactation Risk summary There are no data on the presence of ravulizumab-cwvz in human milk, the effect on the breastfed child, or the effect on milk production. Since many medicinal products and immunoglobulins are secreted into human milk, and because of the potential for serious adverse reactions in a nursing child, breastfeeding should be discontinued during treatment and for 8 months after the final dose. 8.4 Pediatric Use The safety and effectiveness of ULTOMIRIS for the treatment of PNH have been established in pediatric patients aged one month and older. Use of ULTOMIRIS for this indication is supported by evidence from adequate and well-controlled trials in adults with additional pharmacokinetic, efficacy and safety data in pediatric patients aged 9 to 17 years [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1) ] . The safety and efficacy for the treatment of pediatric and adult patients with PNH appear similar. Use of ULTOMIRIS in pediatric patients with PNH aged less than 9 years and body weight < 30 kg is based on extrapolation of pharmacokinetic / pharmacodynamic (PK/PD), and efficacy and safety data from aHUS and PNH clinical studies [see Clinical Pharmacology (12.3) and Clinical Studies (14) ] . The safety and effectiveness of ULTOMIRIS for the treatment of aHUS have been established in pediatric patients aged one month and older. Use of ULTOMIRIS for this indication is supported by evidence from adequate and well-controlled studies in adults with additional pharmacokinetic, safety, and efficacy data in pediatric patients aged 10 months to < 17 years. The safety and efficacy of ULTOMIRIS for the treatment of aHUS appear similar in pediatric and adult patients [see Adverse Reactions (6.1) , and Clinical Studies (14.2) ] . The safety and effectiveness of ULTOMIRIS for the treatment of gMG or NMOSD in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of ULTOMIRIS did not include sufficient numbers of subjects aged 65 and over (58 patients with PNH, 9 with aHUS, 54 with gMG, and 7 with NMOSD) to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients.

Description
Ravulizumab-cwvz, a complement inhibitor, is a humanized monoclonal antibody (mAb) produced in Chinese hamster ovary (CHO) cells. Ravulizumab-cwvz consists of 2 identical 448 amino acid heavy chains and 2 identical 214 amino acid light chains and has a molecular weight of approximately 148 kDa. The constant regions of ravulizumab-cwvz include the human kappa light chain constant region, and the protein engineered "IgG2/4" heavy chain constant region. The heavy chain CH1 domain, hinge region, and the first 5 amino acids of the CH2 domain match the human IgG2 amino acid sequence, residues 6 to 36 in the CH2 region (common to both human IgG2 and IgG4 amino acid sequences), while the remainder of the CH2 domain and the CH3 domain match the human IgG4 amino acid sequence. The heavy and light chain variable regions that form the human C5 binding site consist of human framework regions grafted to murine complementarity-determining regions. ULTOMIRIS (ravulizumab-cwvz) injection is a sterile, translucent, clear to yellowish color, preservative-free solution for intravenous use. Each single-dose vial contains 300 mg or 1,100 mg ravulizumab-cwvz at a concentration of 100 mg/mL with a pH of 7.4. Each mL also contains L-arginine (4.33 mg), polysorbate 80 (0.5 mg) (vegetable origin), sodium phosphate dibasic (4.42 mg), sodium phosphate monobasic (4.57 mg), sucrose (50 mg), and Water for Injection, USP.
Mechanism of action
12.1 Mechanism of Action Ravulizumab-cwvz is a terminal complement inhibitor that specifically binds to the complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a (the proinflammatory anaphylatoxin) and C5b (the initiating subunit of the membrane attack complex [MAC or C5b-9]) thus preventing MAC formation. ULTOMIRIS inhibits terminal complement-mediated intravascular hemolysis in patients with PNH and complement-mediated thrombotic microangiopathy (TMA) in patients with aHUS. The precise mechanism by which ravulizumab-cwvz 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. The precise mechanism by which ravulizumab-cwvz exerts its therapeutic effect in NMOSD is unknown, but is presumed to involve inhibition of aquaporin-4 antibody-induced terminal complement C5b-9 deposition.

Advise the patients and/or caregivers to read the FDA-approved patient labeling (Medication Guide). Serious Meningococcal Infections Advise patients of the risk of serious meningococcal infection. Inform patients of the need to complete or update their meningococcal vaccinations at least 2 weeks prior to receiving the first dose of ULTOMIRIS or receive antibacterial drug prophylaxis if ULTOMIRIS treatment must be initiated immediately and they have not been previously vaccinated. Inform patients of the requirement to be revaccinated according to current ACIP recommendations for meningococcal infection while on ULTOMIRIS therapy [see Warnings and Precautions (5.1) ] . Inform patients that vaccination may not prevent serious meningococcal infection and to seek immediate medical attention if the following signs or symptoms occur [see Warnings and Precautions (5.1) ] : fever fever and a rash headache with nausea or vomiting fever with high heart rate headache and a fever headache with a stiff neck or stiff back confusion muscle aches with flu-like symptoms eyes sensitive to light Inform patients that they will be given a Patient Safety Card for ULTOMIRIS that they should carry with them at all times during and for 8 months following treatment with ULTOMIRIS. This card describes symptoms which, if experienced, should prompt the patient to immediately seek medical evaluation. ULTOMIRIS and SOLIRIS REMS ULTOMIRIS is available only through a restricted program called ULTOMIRIS and SOLIRIS REMS [see Warnings and Precautions (5.2) ] . Inform the patient of the following notable requirements: Patients must receive counseling about the risk of serious meningococcal infections. Patients must receive written educational materials about this risk. Patients must be instructed to carry the Patient Safety Card with them at all times during and for 8 months following treatment with ULTOMIRIS. Patients must be instructed to complete or update meningococcal vaccines for serogroups A, C, W, Y and B per ACIP recommendations as directed by the prescriber prior to treatment with ULTOMIRIS. Patients must receive antibiotics as directed by the prescriber if they are not up to date with meningococcal vaccines and have to start ULTOMIRIS right away. Other Infections Counsel patients of the increased risk of infections, particularly those due to encapsulated bacteria, especially Neisseria species. Advise patients of the need for vaccination against meningococcal infections according to current medical guidelines. Counsel patients about gonorrhea prevention and advise regular testing for patients at risk. Advise patients to report any new signs and symptoms of infection. Discontinuation Inform patients with PNH or aHUS that they may develop serious hemolysis or TMA, respectively, when ULTOMIRIS is discontinued and that they will be monitored by their healthcare professional for at least 16 weeks for PNH or at least 12 months for aHUS following ULTOMIRIS discontinuation [see Warnings and Precautions (5.4) ] . Inform patients who discontinue ULTOMIRIS to keep the Patient Safety Card with them for 8 months after the last ULTOMIRIS dose, because the increased risk of meningococcal infection persists for several months following discontinuation of ULTOMIRIS.

Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ULTOMIRIS during pregnancy.
