Dapagliflozin

12.1 Mechanism of Action Sodium-glucose cotransporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Dapagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, dapagliflozin reduces reabsorption of filtered glucose and thereby promotes urinary glucose excretion. Dapagliflozin also reduces sodium reabsorption and increases the delivery of sodium to the distal tubule. This may influence several physiological functions including, but not restricted to, lowering both pre- and afterload of the heart and downregulation of sympathetic activity, and decreased intraglomerular pressure which is believed to be mediated by increased tubuloglomerular feedback.

1 INDICATIONS AND USAGE FARXIGA (dapagliflozin) is indicated: • To reduce the risk of sustained eGFR decline, end-stage kidney disease, cardiovascular death, and hospitalization for heart failure in adults with chronic kidney disease at risk of progression. • To reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit in adults with heart failure. • To reduce the risk of hospitalization for heart failure in adults with type 2 diabetes mellitus and either established cardiovascular disease or multiple cardiovascular risk factors. • As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Limitations of Use • FARXIGA is not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus [see Warnings and Precautions (5.1) ] . • FARXIGA is not recommended for use to improve glycemic control in adults with type 2 diabetes mellitus with an eGFR less than 45 mL/min/1.73 m 2 . FARXIGA is likely to be ineffective in this setting based upon its mechanism of action. • FARXIGA is not recommended for the treatment of chronic kidney disease in patients with polycystic kidney disease or patients requiring or with a recent history of immunosuppressive therapy for kidney disease. FARXIGA is not expected to be effective in these populations.

2 DOSAGE AND ADMINISTRATION • Assess volume status and correct volume depletion before initiating. (2.1) eGFR (mL/min/1.73 m 2 ) Recommended Dose eGFR 45 or greater To improve glycemic control, the recommended starting dose is 5 mg orally once daily. Dose can be increased to 10 mg orally once daily for additional glycemic control. For all other indications, the recommended starting dose is 10 mg orally once daily. eGFR 25 to less than 45 10 mg orally once daily eGFR less than 25 Initiation is not recommended; however, patients may continue 10 mg orally once daily to reduce the risk of eGFR decline, ESKD, CV death and hHF. • Withhold FARXIGA for at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting. (2.3) 2.1 Prior to Initiation of FARXIGA Assess renal function prior to initiation of FARXIGA therapy and then as clinically indicated [see Warnings and Precautions (5.2) ]. Assess volume status. In patients with volume depletion, correct this condition before initiating FARXIGA [see Warnings and Precautions (5.2) and Use in Specific Populations (8.5 , 8.6) ] . 2.2 Recommended Dosage See Table 1 for dosage recommendations based on estimated glomerular filtration rate (eGFR). Table 1: Recommended Dosage eGFR (mL/min/1.73 m 2 ) Recommended Dose eGFR 45 or greater To improve glycemic control, the recommended starting dose is 5 mg orally once daily.

FARXIGA has been evaluated in clinical trials in patients with type 2 diabetes mellitus, in patients with heart failure, and in patients with chronic kidney disease. The overall safety profile of FARXIGA was consistent across the studied indications. Severe hypoglycemia and diabetic ketoacidosis (DKA) were observed only in patients with diabetes mellitus. Clinical Trials in Patients with Type 2 Diabetes Mellitus Pool of 12 Placebo-Controlled Studies for FARXIGA 5 and 10 mg for Glycemic Control The data in Table 2 is derived from 12 glycemic control placebo-controlled studies in patients with type 2 diabetes mellitus ranging from 12 to 24 weeks. In 4 studies FARXIGA was used as monotherapy, and in 8 studies FARXIGA was used as add-on to background antidiabetic therapy or as combination therapy with metformin [see Clinical Studies (14.1) ]. These data reflect exposure of 2338 patients to FARXIGA with a mean exposure duration of 21 weeks. Patients received placebo (N=1393), FARXIGA 5 mg (N=1145), or FARXIGA 10 mg (N=1193) once daily. The mean age of the population was 55 years and 2% were older than 75 years of age. Fifty percent (50%) of the population were male; 81% were White, 14% were Asian, and 3% were Black or African American. At baseline, the population had diabetes for an average of 6 years, had a mean hemoglobin A1c (HbA1c) of 8.3%, and 21% had established microvascular complications of diabetes. Baseline renal function was normal or mildly impaired in 92% of patients and moderately impaired in 8% of patients (mean eGFR 86 mL/min/1.73 m 2 ). Table 2 shows common adverse reactions associated with the use of FARXIGA. These adverse reactions were not present at baseline, occurred more commonly on FARXIGA than on placebo, and occurred in at least 2% of patients treated with either FARXIGA 5 mg or FARXIGA 10 mg.

7 DRUG INTERACTIONS Table 5: Clinically Relevant Interactions with FARXIGA Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when FARXIGA is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) [see Warnings and Precautions (5.4) ] . Intervention Concomitant use may require lower doses of insulin or the insulin secretagogue to reduce the risk of hypoglycemia. Lithium Clinical Impact Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently during FARXIGA initiation and dosage changes. Positive Urine Glucose Test Clinical Impact SGLT2 inhibitors increase urinary glucose excretion and will lead to positive urine glucose tests. Intervention Monitoring glycemic control with urine glucose tests is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control. Interference with 1,5-anhydroglucitol (1,5-AG) Assay Clinical Impact Measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors. Intervention Monitoring glycemic control with 1,5-AG assay is not recommended. Use alternative methods to monitor glycemic control. See full prescribing information for information on drug interactions and interference of FARXIGA with laboratory tests. (7)
