Dapagliflozin

8.1 Pregnancy Risk Summary Based on animal data showing adverse renal effects, FARXIGA is not recommended during the second and third trimesters of pregnancy. Limited data with FARXIGA in pregnant women are not sufficient to determine drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes and untreated heart failure in pregnancy (see clinical considerations ). In animal studies, adverse renal pelvic and tubule dilatations, that were not fully reversible, were observed in rats when dapagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy, at all doses tested; the lowest of which provided an exposure 15-times the 10 mg clinical dose ( see Data ). The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with a HbA1c greater than 7% and has been reported to be as high as 20 to 25% in women with HbA1c greater than 10%. The estimated background risk of 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 embryofetal risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Animal Data Dapagliflozin dosed directly to juvenile rats from postnatal day (PND) 21 until PND 90 at doses of 1, 15, or 75 mg/kg/day, increased kidney weights and increased the incidence of renal pelvic and tubular dilatations at all dose levels. Exposure at the lowest dose tested was 15-times the 10 mg clinical dose (based on AUC). The renal pelvic and tubular dilatations observed in juvenile animals did not fully reverse within a 1-month recovery period. In a prenatal and postnatal development study, dapagliflozin was administered to maternal rats from gestation day 6 through lactation day 21 at doses of 1, 15, or 75 mg/kg/day, and pups were indirectly exposed in utero and throughout lactation. Increased incidence or severity of renal pelvic dilatation was observed in 21-day-old pups offspring of treated dams at 75 mg/kg/day (maternal and pup dapagliflozin exposures were 1415-times and 137-times, respectively, the human values at the 10 mg clinical dose, based on AUC). Dose-related reductions in pup body weights were observed at greater or equal to 29-times the 10 mg clinical dose (based on AUC). No adverse effects on developmental endpoints were noted at 1 mg/kg/day (19-times the 10 mg clinical dose, based on AUC). These outcomes occurred with drug exposure during periods of renal development in rats that corresponds to the late second and third trimester of human development. In embryofetal development studies in rats and rabbits, dapagliflozin was administered throughout organogenesis, corresponding to the first trimester of human pregnancy. In rats, dapagliflozin was neither embryolethal nor teratogenic at doses up to 75 mg/kg/day (1441-times the 10 mg clinical dose, based on AUC). Dose-related effects on the rat fetus (structural abnormalities and reduced body weight) occurred only at higher dosages, equal to or greater than 150 mg/kg (more than 2344-times the 10 mg clinical dose, based on AUC), which were associated with maternal toxicity. No developmental toxicities were observed in rabbits at doses up to 180 mg/kg/day (1191-times the 10 mg clinical dose, based on AUC).

• Pregnancy: Advise females of the potential risk to a fetus especially during the second and third trimesters. (8.1) • Lactation: Not recommended when breastfeeding. (8.2) • Geriatrics: Higher incidence of adverse reactions related to hypotension. ( 8.5 ) • Renal Impairment: Higher incidence of adverse reactions related to volume depletion.

Dapagliflozin is present in the milk of lactating rats (see Data ) . However, due to species-specific differences in lactation physiology, the clinical relevance of these data is not clear. Since human kidney maturation occurs in utero and during the first 2 years of life when lactational exposure may occur, there may be risk to the developing human kidney. Because of the potential for serious adverse reactions in breastfed infants, advise women that use of FARXIGA is not recommended while breastfeeding. Data Dapagliflozin was present in rat milk at a milk/plasma ratio of 0.49, indicating that dapagliflozin and its metabolites are transferred into milk at a concentration that is approximately 50% of that in maternal plasma. Juvenile rats directly exposed to dapagliflozin showed risk to the developing kidney (renal pelvic and tubular dilatations) during maturation. 8.4 Pediatric Use The safety and effectiveness of FARXIGA as an adjunct to diet and exercise to improve glycemic control in type 2 diabetes mellitus have been established in pediatric patients aged 10 years and older. Use of FARXIGA for this indication is supported by a 26-week placebo-controlled trial with a 26-week extension in 157 pediatric patients aged 10 to 17 years with type 2 diabetes mellitus, pediatric pharmacokinetic data, and trials in adults with type 2 diabetes mellitus [see Clinical Pharmacology (12.3) and Clinical Studies (14.1 , 14.2) ] . The safety profile observed in the placebo-controlled trial in pediatric patients with type 2 diabetes mellitus was similar to that observed in adults [see Adverse Reactions (6.1) ] . The safety and effectiveness of FARXIGA for glycemic control in type 2 diabetes mellitus have not been established in pediatric patients less than 10 years of age. The safety and effectiveness of FARXIGA have not been established in pediatric patients to reduce the risk of [see Indications and Usage (1) ] : • sustained eGFR decline, end-stage kidney disease, CV death, and hospitalization for heart failure in patients with chronic kidney disease at risk of progression. • CV death, hospitalization for heart failure, and urgent heart failure visit in patients with heart failure. • hospitalization for heart failure in patients with type 2 diabetes mellitus and either established CV disease or multiple CV risk factors. 8.5 Geriatric Use No FARXIGA dosage change is recommended based on age. A total of 1424 (24%) of the 5936 FARXIGA-treated patients were 65 years and older and 207 (3.5%) patients were 75 years and older in a pool of 21 double-blind, controlled, clinical trials assessing the efficacy of FARXIGA in improving glycemic control in type 2 diabetes mellitus. After controlling for level of renal function (eGFR), efficacy was similar for patients under age 65 years and those 65 years and older. In patients ≥65 years of age, a higher proportion of patients treated with FARXIGA for glycemic control had adverse reactions of hypotension [see Warnings and Precautions (5.2) and Adverse Reactions (6.1) ] . In the DAPA-CKD, DAPA-HF and DELIVER trials, safety and efficacy were similar for patients aged 65 years and younger and those older than 65. In the DAPA-HF study, 2714 (57%) out of 4744 patients with HFrEF were older than 65 years. In the DELIVER study, 4759 (76%) out of 6263 patients with heart failure (LVEF >40%) were older than 65 years. In the DAPA-CKD study, 1818 (42%) out of 4304 patients with CKD were older than 65 years. 8.6 Renal Impairment FARXIGA was evaluated in 4304 adult patients with chronic kidney disease (eGFR 25 to 75 mL/min/1.73 m2) in the DAPA-CKD trial. FARXIGA was also evaluated in 1926 adult patients with an eGFR of 30 to 60 mL/min/1.73 m2 in the DAPA-HF trial. The safety profile of FARXIGA across eGFR subgroups in these studies was consistent with the known safety profile [see Adverse Reactions (6.1) and Clinical Studies (14.4 , 14.5 )]. FARXIGA was evaluated in two glycemic control adult trials that included patients with type 2 diabetes mellitus with moderate renal impairment (an eGFR of 45 to less than 60 mL/min/1.73 m2 [see Clinical Studies (14.1) ], and an eGFR of 30 to less than 60 mL/min/1.73 m2, respectively). Patients with diabetes and renal impairment using FARXIGA may be more likely to experience hypotension and may be at higher risk for acute kidney injury secondary to volume depletion. In the trial of adult patients with an eGFR 30 to less than 60 mL/min/1.73 m2, 13 patients receiving FARXIGA experienced bone fractures compared to none receiving placebo. Use of FARXIGA for glycemic control in patients without established CV disease or CV risk factors is not recommended when eGFR is less than 45 mL/min/1.73 m2 [see Dosage and Administration (2.1) ]. Efficacy and safety trials with FARXIGA did not enroll patients with an eGFR less than 25 mL/min/1.73 m 2 or on dialysis. Once enrolled in the DAPA-CKD and DELIVER trials, adult patients were not required to discontinue therapy if eGFR fell below 25 mL/min/1.73 m 2 or if dialysis was initiated. Once enrolled in the DAPA-HF trial, adult patients were not required to discontinue therapy if eGFR fell below 30 mL/min/1.73 m 2 or if dialysis was initiated [see Dosage and Administration (2.3) and Clinical Studies (14.4, 14.5) ] . 8.7 Hepatic Impairment No dose adjustment is recommended for patients with mild, moderate, or severe hepatic impairment. However, the benefit-risk for the use of dapagliflozin in patients with severe hepatic impairment should be individually assessed since the safety and efficacy of dapagliflozin have not been specifically studied in this population [see Clinical Pharmacology (12.3) ] .
