Dosing in kidney impairment
Renal Impairment The recommended dosage of REDEMPLO in patients with mild or moderate renal impairment (eGFR ≥30 to <90 mL/min) is the same as those with normal renal function. The impact of severe renal impairment or end stage renal disease is not known [see Clinical Pharmacology] .
Dosing in liver impairment
Hepatic Impairment The recommended dosage of REDEMPLO in patients with mild hepatic impairment [total bilirubin ≤1 times the upper limit of normal (ULN) and AST >1 times ULN, or total bilirubin >1.0 to 1.5 times ULN and any AST] is the same as those with normal hepatic function. The impact of moderate or severe hepatic impairment is not known [see Clinical Pharmacology] .

Important Administration Instructions Prior to initiation, train patients and/or caregivers on proper preparation and administration of REDEMPLO [see Instructions for Use ] . Adhere to a low-fat diet (less than or equal to 20 grams fat per day) in conjunction with REDEMPLO. Visually inspect the REDEMPLO pre-filled syringe prior to administration.
The solution should be clear and colorless to yellow. Do not use if cloudiness, particulate matter, or discoloration is observed prior to administration. Inject REDEMPLO subcutaneously into the front of the thigh or abdomen. The outer area of the upper arm can be used as an injection site if a healthcare provider or caregiver administers the injection.
Do not inject REDEMPLO in an area where the skin is damaged (tender, bruised, red, hard, or cut). Do not inject into areas with scars or stretch marks. If a dose is missed, administer REDEMPLO as soon as possible. Resume dosing every 3 months from the date of the most recently administered dose.

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are insufficient data on REDEMPLO use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Patients with FCS are at risk for pancreatitis during pregnancy because of defects in lipid metabolism and increased triglyceride levels (see Clinical Considerations ) . In animal reproduction studies, no adverse drug-related developmental effects were observed in pregnant rats or rabbits with subcutaneous administration of plozasiran during organogenesis up to 23 and 140 times, respectively, the maximum recommended human dose (MRHD) (see Data ) .
The background risk of major birth defects and miscarriage for 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. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Triglyceride levels increase during the third trimester of pregnancy. In patients with underlying defects in lipid metabolism, such as FCS, severe gestational hypertriglyceridemia may occur, increasing the risk of acute pancreatitis during pregnancy.
Data Animal Data In an embryo-fetal development study, pregnant rats were administered plozasiran by subcutaneous injection at 0, 5, 15, or 60 mg/kg, or 60 mg/kg rat specific surrogate, once daily during the period of organogenesis (gestational days 6 to 17). There was no evidence of drug-related embryo-fetal toxicity or fetal malformations up to 60 mg/kg plozasiran [23 times the MRHD based on body surface area (BSA)].
At maternally toxic doses there were embryo-fetal toxicities including increases in post-implantation loss and mean number of late resorptions at 60 mg/kg (23 times the MRHD based on BSA), early deliveries, reduced fetal body weight, and fetal skeletal developmental variations at ≥15 mg/kg (6 times the MRHD based on BSA). No adverse embryo-fetal developmental effects were observed from a single subcutaneous administration of 50 mg/kg plozasiran (19 times the MRHD based on BSA) or the rat specific surrogate to pregnant rats on gestation day 10.
In an embryo-fetal development study in pregnant rabbits, plozasiran was administered by subcutaneous injection at 0, 30, 60, or 180 mg/kg/day once daily during the period of organogenesis (gestational days 7 to 19). No evidence (of embryo-fetal toxicity or developmental abnormalities) was observed up to 180 mg/kg (140 times the MRHD based on BSA). In a rat pre- and…
