Dosing in kidney impairment
Discontinue RYZNEUTA if sickle cell crisis occurs. 5.5 Glomerulonephritis Glomerulonephritis has occurred in patients receiving rhG-CSF products. The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Generally, events of glomerulonephritis resolved after dose-reduction or discontinuation of rhG-CSF.

Administration RYZNEUTA is administered subcutaneously via a single-dose prefilled syringe by a healthcare professional. Prior to use‚ remove the carton from the refrigerator (keeping the prefilled syringe inside the carton) for a minimum of 30 minutes to allow the product to reach room temperature. Discard any product left at room temperature for greater than 48 hours.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer RYZNEUTA if discoloration or particulates are observed. Caution: This product contains natural rubber latex which may cause allergic reactions.
The needle cap on the prefilled syringe contains natural rubber; people with latex allergies should not administer this product. The RYZNEUTA prefilled syringe does not bear graduation marks and is intended only to deliver the entire contents of the syringe (20 mg/mL) for direct administration to adult patients. Administer injection by pinching the skin and holding.
Inject into the abdomen, the back or side of the upper arms, or the thighs. Rotate injection sites. Do not inject into scar tissue or areas that are reddened, inflamed, or swollen. If injecting into the abdomen, avoid a 2-inch diameter circle around the navel. Once the entire dose has been injected, the needle safety device will be triggered, pulling the needle automatically from the skin, and into the barrel; the entire needle will be covered by the needle guard.

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Although available data with RYZNEUTA use in pregnant women are insufficient to establish whether there is a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, there are available data from published studies in pregnant women exposed to other human G-CSF products. These studies have not established an association of G-CSF product use during pregnancy with major birth defects, miscarriage, or adverse maternal or fetal outcomes.
In animal studies, no evidence of reproductive/developmental toxicity occurred in the offspring of pregnant rats and rabbits that received cumulative doses of efbemalenograstim alfa-vuxw approximately 2.6 and 0.7 times, respectively, the recommended human dose (based on body surface area). The estimated 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 risks of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data Animal Data Three studies were conducted in pregnant rats dosed with efbemalenograstim alfa-vuxw at cumulative doses up to approximately 2.6 times the recommended human dose at the following stages of gestation: during the period of organogenesis, from mating through the first half of pregnancy, and from the first trimester through delivery and lactation. No evidence of fetal loss or structural malformations was observed in any study. Growth and learning were also unaffected.
Pregnant rabbits were dosed with efbemalenograstim alfa-vuxw every other day during organogenesis at cumulative doses up to 0.7 times the recommended human dose showed no signs of fetal loss or structural malformations. Maternal toxicity (decreased weight gain or weight loss and/or death) was observed when higher cumulative doses of efbemalenograstim alfa-vuxw were used in an early dose-ranging study in rabbits.
