Important Recommendation Prior to NULIBRY Treatment NULIBRY is intended for administration by a healthcare provider. If deemed appropriate by a healthcare provider, NULIBRY may be administered at home by the patient's caregiver. If NULIBRY can be administered by a caregiver/patient, advise them to read the detailed instructions on the preparation, administration, storage, and disposal of NULIBRY for caregivers [see Instructions for Use ].
Recommended Dosage and Administration Recommended Dosage and Administration in Patients Less Than One Year of Age (by gestational age) The recommended dosage regimen of NULIBRY in patients less than one year of age (by gestational age), is based on actual body weight as shown in Table 1 . Administer NULIBRY by intravenous infusion once daily.
For dose volumes less than 2 mL, consider administering by slow intravenous push using syringe administration [ see Dosage and Administration ] . [See table below.] 0.9 mg/kg once daily Recommended Dosage and Administration in Patients One Year of Age or Older For patients one year of age or older, the recommended dosage of NULIBRY is 0.9 mg/kg (based on actual body weight) administered as an intravenous infusion once daily.
Missed Dose If a NULIBRY dose is missed, administer the missed dose as soon as possible. Administer the next scheduled dose at least 6 hours after the administration of the missed dose.
Preparation and Administration Instructions Preparation NULIBRY must be reconstituted prior to use. Use aseptic technique during preparation and follow these instructions: Calculate the dose based on the patient's weight to determine the number of vials needed and total reconstituted dose volume. More than one vial may be needed to achieve the calculated dose.
Remove the required number of vials from the freezer to allow them to reach room temperature (by hand warming for 3 to 5 minutes or exposing to ambient air for approximately 30 minutes). Reconstitute each NULIBRY vial with 5 mL of Sterile Water for Injection, USP. Gently swirl the vial continuously until the powder is completely dissolved.
DO NOT shake. After reconstitution, the final concentration of NULIBRY reconstituted solution is 9.5 mg/5 mL (1.9 mg/mL). Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Reconstituted NULIBRY is a clear and colorless to pale yellow solution.
Do not use if there are particles present or if the solution is discolored. Withdraw the calculated dose volume from the vial(s) using a syringe. Discard any unused solution remaining in the vial(s). Administration If reconstituted NULIBRY solution in the vial is refrigerated, allow it to come to room temperature (by hand warming for 3 to 5 minutes or exposing to ambient air for approximately 30 minutes) before administration.
Administer NULIBRY as an intravenous infusion using an infusion pump at a rate of 1.5 mL per minute. Use non-DEHP tubing and a 0.2 micron filter to administer the total reconstituted dose volume. For dose volumes less than 2 mL, consider administering by slow intravenous push over 1 to 2 minutes using syringe administration.
Complete administration of NULIBRY within 4 hours of reconstitution [ see Dosage and Administration ] . Do not mix NULIBRY with other drugs. Do not administer as an infusion with other drugs.
Home Administration If deemed appropriate by a healthcare provider, NULIBRY may be administered at home by the patient's caregiver. If NULIBRY can be administered by a caregiver/patient, advise them to read the detailed instructions on the preparation, administration, storage, and disposal of NULIBRY for caregivers [see Instructions for Use ].
Storage of Reconstituted Solution If the reconstituted NULIBRY solution in the vial is not used immediately, store at room temperature at 15°C to 25°C (59°F to 77°F) or refrigerate at 2°C to 8°C (36°F to 46°F) for up to 4 hours (inclusive of infusion time), or discard. Do not heat. Do not re-freeze NULIBRY after reconstitution.
Do not shake.

Pregnancy
8.1 Pregnancy Risk Summary There are no available data on NULIBRY use in pregnant females to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal reproduction studies, no adverse developmental outcomes occurred at dose exposures 32-89 times the human exposure at the maximum recommended human dose (MRHD) of 0.9 mg/kg/day (see Data ). The background risk of major birth defects and miscarriage for the indicated population 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% to 4% and 15% to 20%, respectively. Data Animal Data In an embryofetal development study, intravenous administration of fosdenopterin to pregnant rabbits once daily during the period of organogenesis (GD 7 to GD 20) at doses up to 200 mg/kg/day (approximately 89 times the human exposure at the MRHD, based on AUC) did not result in adverse developmental effects.
In a pre- and postnatal development study, subcutaneous administration of fosdenopterin to pregnant mice once daily throughout pregnancy and lactation (GD 6 to Lactation Day 20) at doses of 50, 100, or 200 mg/kg/day (up to 32 times the human exposure at the MRHD, based on AUC) did not result in adverse developmental effects.

Not the price at the counterThese are not what a patient pays at the pharmacy counter. They are what pharmacies, health plans, and government buyers pay, before manufacturer rebates. A patient's cost depends on their insurance (copay, coinsurance, or deductible) or the pharmacy's cash price.
