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.

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.

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.

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.

Dosing Considerations

Supplemental Dose of ULTOMIRIS

Plasma exchange (PE), plasmapheresis (PP), and intravenous immunoglobulin (IVIg) have been shown to reduce ULTOMIRIS serum levels. A supplemental dose of ULTOMIRIS is required in the setting of PE, PP, or IVIg (Table 3).

Table 3: Supplemental Dose of ULTOMIRIS after PE, PP, or IVIg*
Body Weight Range (kg)	Most Recent ULTOMIRIS Dose (mg)	Supplemental Dose (mg) following each PE or PP Intervention	Supplemental Dose (mg) following Completion of an IVIg Cycle
Abbreviations: IVIg = intravenous immunoglobulin; PE = plasma exchange; PP = plasmapheresis
* See Table 6 and Table 9 for selection of the proper total volume and maximum infusion rate
40 to less than 60	2,400	1,200	600
40 to less than 60	3,000	1,500	600
60 to less than 100	2,700	1,500	600
60 to less than 100	3,300	1,800	600
100 or greater	3,000	1,500	600
100 or greater	3,600	1,800	600
Timing of ULTOMIRIS Supplemental Dose		Within 4 hours following each PE or PP intervention	Within 4 hours following completion of an IVIg cycle

Preparation and Administration

Preparation of ULTOMIRIS Vials for Intravenous Administration

Each vial of ULTOMIRIS is intended for single-dose only.

ULTOMIRIS vials are for intravenous administration by a healthcare provider and are intended for intravenous administration only.

Dilute before use.

Do not mix ULTOMIRIS 100 mg/mL (3 mL and 11 mL vials) and 10 mg/mL (30 mL vial) concentrations together.

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.

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 for the 3 mL and 11 mL vial sizes or
5 mg/mL for the 30 mL vial size.

The product should be mixed gently. Do not shake. Protect from light. Do not freeze.

Refer to the following reference tables for IV preparation and minimum infusion duration:

ULTOMIRIS 100 mg/mL (3 mL and 11 mL vials): see Table 4 (loading doses), Table 5 (maintenance doses), and Table 6 (supplemental doses)
ULTOMIRIS 10 mg/mL (30 mL vial): see Table 7 (loading doses), Table 8 (maintenance doses), and Table 9 (supplemental doses)

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 6 hours if prepared with ULTOMIRIS 30 mL vials or within 4 hours if prepared with ULTOMIRIS 3 mL or 11 mL vials.

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 for the 3 mL and 11 mL vial sizes or
5 mg/mL for the 30 mL vial size.

Prior to administration, allow the admixture to adjust to room temperature (18°C - 25°C, 64°F - 77°F). Do not heat the admixture 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.

After administration of ULTOMIRIS, flush the entire line with 0.9% Sodium Chloride Injection, USP.
