Boxed warning

WARNING: SERIOUS MENINGOCOCCAL INFECTIONS ZILBRYSQ, a complement inhibitor, increases 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 ZILBRYSQ, unless the risks of delaying therapy outweigh the risk of developing a serious infection.

Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccination 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 ZILBRYSQ 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, ZILBRYSQ is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called ZILBRYSQ REMS [see Warnings and Precautions (5.2) ] . WARNING: SERIOUS MENINGOCOCCAL INFECTIONS See full prescribing information for complete boxed warning. ZILBRYSQ increases the risk of serious and life-threatening infections caused by Neisseria meningitidis . ( 5.1 ) Complete or update meningococcal vaccination at least 2 weeks prior to the first dose of ZILBRYSQ, unless the risks of delaying ZILBRYSQ outweigh the risks of developing a serious infection.

Preparation and administration

Your numbers for zilucoplan. Take vial strength, diluent, and limits from the label below.

Basis

Enter a dose to see draw volume, final concentration, and rates.

Preparation Instructions ZILBRYSQ prefilled syringes can be stored in a refrigerator in the original carton. ZILBRYSQ can also be stored at room temperature in the original carton for up to 3 months or until the expiration date, whichever occurs first. If stored in the refrigerator: Before injecting, take 1 ZILBRYSQ prefilled syringe out of the refrigerator and place it on a clean, flat surface.

Allow ZILBRYSQ to reach room temperature out of direct sunlight (30 to 45 minutes). Do not heat or place in microwave. Immediately return the carton with the other prefilled syringes to the refrigerator. If stored at room temperature: Remove 1 ZILBRYSQ prefilled syringe from the carton. Do not return ZILBRYSQ to the refrigerator after it has been stored at room temperature.

Visually inspect ZILBRYSQ for particulate matter and discoloration prior to administration. ZILBRYSQ is a clear to slightly opalescent, colorless solution. Do not use if the solution contains visible particles, is cloudy, or if foreign particulate matter is present. ZILBRYSQ does not contain preservatives; unused portions of drug remaining in the syringe should be discarded.

Each prefilled syringe is single-dose only.

Administration Instructions ZILBRYSQ is intended for use under the guidance and supervision of a healthcare professional. Patients may self-inject ZILBRYSQ after training in subcutaneous injection technique. Provide proper training to patients and/or caregivers on the subcutaneous injection technique of ZILBRYSQ according to the "Instructions for Use" [see Instructions for Use ] .

Administer ZILBRYSQ subcutaneously into areas of the abdomen, thighs, or back of the upper arms that are not tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks. Rotate injection sites for each administration. Administration of ZILBRYSQ in the upper, outer arm should be performed by a caregiver.

When using ZILBRYSQ prefilled syringes, inject the full contents of the single-dose prefilled syringe. Discard ZILBRYSQ prefilled syringe after use. Do not reuse. Instruct the patient that the daily dose should be administered at approximately the same time each day. If a dose is missed, administer the dose as soon as possible.

Thereafter, resume dosing at the regular scheduled time. Do not administer more than 1 dose per day.

Pregnancy and lactation

Pregnancy

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ZILBRYSQ during pregnancy. Patients or healthcare providers may contact UCBCares at 1-844-599-CARE (2273) or email ucbcares@ucb.com, so that information about the exposure of ZILBRYSQ during pregnancy and/or breastfeeding can be collected. Risk Summary There are no available data on ZILBRYSQ use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.

Administration of zilucoplan to pregnant monkeys resulted in increases in embryofetal death at maternal exposures similar to those in humans at therapeutic doses (see Animal Data ) . All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background rate of major birth defects and miscarriage in the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data Animal Data Subcutaneous administration of zilucoplan (0, 1, 2, or 4 mg/kg/day) to pregnant monkeys throughout gestation resulted in an increase in embryofetal death at all doses, in the absence of maternal toxicity. A no effect dose for adverse developmental effects in monkeys was not identified. The lowest dose tested was associated with maternal exposures (AUC) similar to that in humans at the maximum recommended human dose of 32.4 mg/day.

Data from an ex vivo human placental transfer model demonstrated transfer of zilucoplan into the fetal compartment at a rate of 0.5% at a steady state plasma concentration of 10 µg/mL zilucoplan, which corresponds to a therapeutic dose of 0.3 mg/kg. The clinical significance of these data in human pregnancies is unknown.

Breastfeeding (LactMed)

Zilucoplan is expected to be degraded into small peptides and amino acids via catabolic pathways in the maternal circulation and infant gastrointestinal tract. It is unlikely to be absorbed by the breastfed infant or adversely affect the infant. No special precautions are required.
