Dapagliflozin has been evaluated in clinical trials in adult and pediatric patients aged 10 years and older with type 2 diabetes mellitus, in adult patients with heart failure, and in adult patients with chronic kidney disease. The overall safety profile of dapagliflozin was consistent across the studied indications. No new adverse reactions were identified in the DAPA-HF and DELIVER heart failure trials, or in the DAPA-CKD trial in patients with chronic kidney disease. Severe hypoglycemia and diabetic ketoacidosis (DKA) were observed only in patients with diabetes mellitus. Clinical Trials for Glycemic Control in Adult Patients with Type 2 Diabetes Mellitus Pool of 12 Placebo-Controlled Adult Trials for Dapagliflozin 5 and 10 mg for Glycemic Control The data in Table 1 is derived from 12 glycemic control placebo-controlled trials in adult patients with type 2 diabetes mellitus ranging from 12 to 24 weeks. In 4 trials dapagliflozin was used as monotherapy, and in 8 trials dapagliflozin 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 adult patients to dapagliflozin with a mean exposure duration of 21 weeks. Patients received placebo (N=1393), dapagliflozin 5 mg (N=1145), or dapagliflozin 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 1 shows common adverse reactions in adults associated with the use of dapagliflozin. These adverse reactions were not present at baseline, occurred more commonly on dapagliflozin than on placebo, and occurred in at least 2% of patients treated with either dapagliflozin 5 mg or dapagliflozin 10 mg.

(N for females: Placebo=677, dapagliflozin 5 mg=581, dapagliflozin 10 mg=598). 1.5 8.4 6.9 Nasopharyngitis 6.2 6.6 6.3 Urinary tract infections Urinary tract infections include the following adverse reactions, listed in order of frequency reported: urinary tract infection, cystitis, Escherichia urinary tract infection, genitourinary tract infection, pyelonephritis, trigonitis, urethritis, kidney infection, and prostatitis. 3.7 5.7 4.3 Back pain 3.2 3.1 4.2 Increased urination Increased urination includes the following adverse reactions, listed in order of frequency reported: pollakiuria, polyuria, and urine output increased. 1.7 2.9 3.8 Male genital mycotic infections Genital mycotic infections include the following adverse reactions, listed in order of frequency reported for males: balanitis, fungal genital infection, balanitis candida, genital candidiasis, genital infection male, penile infection, balanoposthitis, balanoposthitis infective, genital infection, and posthitis. (N for males: Placebo=716, dapagliflozin 5 mg=564, dapagliflozin 10 mg=595). 0.3 2.8 2.7 Nausea 2.4 2.8 2.5 Influenza 2.3 2.7 2.3 Dyslipidemia 1.5 2.1 2.5 Constipation 1.5 2.2 1.9 Discomfort with urination 0.7 1.6 2.1 Pain in extremity 1.4 2.0 1.7 Pool of 13 Placebo-Controlled Adult Trials for Dapagliflozin 10 mg for Glycemic Control Dapagliflozin 10 mg was also evaluated in a larger glycemic control placebo-controlled trial pool in adult patients with type 2 diabetes mellitus. This pool combined 13 placebo-controlled trials, including 3 monotherapy trials, 9 add-on to background antidiabetic therapy trials, and an initial combination with metformin trial. Across these 13 trials, 2360 patients were treated once daily with dapagliflozin 10 mg for a mean duration of exposure of 22 weeks. The mean age of the population was 59 years and 4% were older than 75 years. Fifty-eight percent (58%) of the population were male; 84% were White, 9% were Asian, and 3% were Black or African American. At baseline, the population had diabetes for an average of 9 years, had a mean HbA1c of 8.2%, and 30% had established microvascular disease. Baseline renal function was normal or mildly impaired in 88% of patients and moderately impaired in 11% of patients (mean eGFR 82 mL/min/1.73 m 2 ). Other Adverse Reactions in Adult Patients with Type 2 Diabetes Mellitus Volume Depletion Dapagliflozin causes an osmotic diuresis, which may lead to a reduction in intravascular volume. Adverse reactions related to volume depletion (including reports of dehydration, hypovolemia, orthostatic hypotension, or hypotension) in adult patients with type 2 diabetes mellitus for the 12 trial and 13 trial, short term, placebo controlled pools and for the DECLARE trial are shown in Table 2 [see Warnings and Precautions (5.2) ]. Table 2: Adverse Reactions Related to Volume Depletion Volume depletion includes reports of dehydration, hypovolemia, orthostatic hypotension, or hypotension. in Clinical Trials in Adults with Type 2 Diabetes Mellitus with Dapagliflozin Pool of 12 Placebo-Controlled Trials Pool of 13 Placebo-Controlled Trials DECLARE Trial Placebo Dapagliflozin 5 mg Dapagliflozin 10 mg Placebo Dapagliflozin 10 mg Placebo Dapagliflozin 10 mg Overall population N (%) N=1393 5 (0.4%) N=1145 7 (0.6%) N=1193 9 (0.8%) N=2295 17 (0.7%) N=2360 27 (1.1%) N=8569 207 (2.4%) N=8574 213 (2.5%) Patient Subgroup n (%) Patients on loop diuretics n=55 1 (1.8%) n=40 0 n=31 3 (9.7%) n=267 4 (1.5%) n=236 6 (2.5%) n=934 57 (6.1%) n=866 57 (6.6%) Patients with moderate renal impairment with eGFR ≥30 and <60 mL/min/1.73 m 2 n=107 2 (1.9%) n=107 1 (0.9%) n=89 1 (1.1%) n=268 4 (1.5%) n=265 5 (1.9%) n=658 30 (4.6%) n=604 35 (5.8%) Patients ≥65 years of age n=276 1 (0.4%) n=216 1 (0.5%) n=204 3 (1.5%) n=711 6 (0.8%) n=665 11 (1.7%) n=3950 121 (3.1%) n=3948 117 (3.0%) Hypoglycemia The frequency of hypoglycemia by trial in adult patients with type 2 diabetes mellitus [see Clinical Studies (14.1) ] is shown in Table 3. Hypoglycemia was more frequent when dapagliflozin was added to sulfonylurea or insulin [see Warnings and Precautions (5.4) ] . Table 3: Incidence of Severe Hypoglycemia Severe episodes of hypoglycemia were defined as episodes of severe impairment in consciousness or behavior, requiring external (third party) assistance, and with prompt recovery after intervention regardless of glucose level. and Hypoglycemia with Glucose <54 mg/dL Episodes of hypoglycemia with glucose <54 mg/dL (3 mmol/L) were defined as reported episodes of hypoglycemia meeting the glucose criteria that did not also qualify as a severe episode. in Controlled Glycemic Control Clinical Trials in Adults with Type 2 Diabetes Mellitus Placebo/Active Control Dapagliflozin 5 mg Dapagliflozin 10 mg Monotherapy (24 weeks) N=75 N=64 N=70 Severe [n (%)] 0 0 0 Glucose <54 mg/dL [n (%)] 0 0 0 Add-on to Metformin (24 weeks) N=137 N=137 N=135 Severe [n (%)] 0 0 0 Glucose <54 mg/dL [n (%)] 0 0 0 Add-on to Glimepiride (24 weeks) N=146 N=145 N=151 Severe [n (%)] 0 0 0 Glucose <54 mg/dL [n (%)] 1 (0.7) 3 (2.1) 5 (3.3) Add-on to Metformin and a Sulfonylurea (24 Weeks) N=109 - N=109 Severe [n (%)] 0 - 0 Glucose <54 mg/dL [n (%)] 3 (2.8) - 7 (6.4) Add-on to Pioglitazone (24 weeks) N=139 N=141 N=140 Severe [n (%)] 0 0 0 Glucose <54 mg/dL [n (%)] 0 1 (0.7) 0 Add-on to DPP4 inhibitor (24 weeks) N=226 – N=225 Severe [n (%)] 0 – 1 (0.4) Glucose <54 mg/dL [n (%)] 1 (0.4) – 1 (0.4) Add-on to Insulin with or without other OADs OAD = oral antidiabetic therapy.

Genital Mycotic Infections In the glycemic control trials in adults, genital mycotic infections were more frequent with dapagliflozin treatment. Genital mycotic infections were reported in 0.9% of patients on placebo, 5.7% on dapagliflozin 5 mg, and 4.8% on dapagliflozin 10 mg, in the 12-trial placebo-controlled pool. Discontinuation from trial due to genital infection occurred in 0% of placebo-treated patients and 0.2% of patients treated with dapagliflozin 10 mg. Infections were more frequently reported in females than in males (see Table 1). The most frequently reported genital mycotic infections were vulvovaginal mycotic infections in females and balanitis in males. Patients with a history of genital mycotic infections were more likely to have a genital mycotic infection during the trial than those with no prior history (10.0%, 23.1%, and 25.0% versus 0.8%, 5.9%, and 5.0% on placebo, dapagliflozin 5 mg, and dapagliflozin 10 mg, respectively). In the DECLARE trial [see Clinical Studies (14.3) ] , serious genital mycotic infections were reported in <0.1% of patients treated with dapagliflozin and <0.1% of patients treated with placebo. Genital mycotic infections that caused trial drug discontinuation were reported in 0.9% of patients treated with dapagliflozin and <0.1% of patients treated with placebo. Hypersensitivity Reactions Hypersensitivity reactions (e.g., angioedema, urticaria, hypersensitivity) were reported with dapagliflozin treatment. In glycemic control trials, serious anaphylactic reactions and severe cutaneous adverse reactions and angioedema were reported in 0.2% of comparator-treated patients and 0.3% of dapagliflozin-treated patients. If hypersensitivity reactions occur, discontinue use of DAPAGLIFLOZIN TABLETS; treat per standard of care and monitor until signs and symptoms resolve. Ketoacidosis in Patients with Diabetes Mellitus In the DECLARE trial [see Clinical Studies (14.3) ] , events of diabetic ketoacidosis (DKA) were reported in 27 out of 8574 adult patients in the dapagliflozin-treated group and 12 out of 8569 adult patients in the placebo group. The events were evenly distributed over the trial period. Laboratory Tests in Adult Patients with Type 2 Diabetes Mellitus Increases in Serum Creatinine and Decreases in eGFR Initiation of SGLT2 inhibitors, including dapagliflozin causes a small increase in serum creatinine and decrease in eGFR. These changes in serum creatinine and eGFR generally occur within two weeks of starting therapy and then stabilize regardless of baseline kidney function. Changes that do not fit this pattern should prompt further evaluation to exclude the possibility of acute kidney injury [see Warnings and Precautions (5.2) ] . In two trials that included adult patients with type 2 diabetes mellitus with moderate renal impairment, the acute effect on eGFR reversed after treatment discontinuation, suggesting acute hemodynamic changes may play a role in the renal function changes observed with dapagliflozin. Increase in Hematocrit In the pool of 13 placebo-controlled trials of glycemic control, increases from baseline in mean hematocrit values were observed in dapagliflozin-treated adult patients starting at Week 1 and continuing up to Week 16, when the maximum mean difference from baseline was observed. At Week 24, the mean changes from baseline in hematocrit were -0.33% in the placebo group and 2.30% in the dapagliflozin 10 mg group. By Week 24, hematocrit values >55% were reported in 0.4% of placebo-treated patients and 1.3% of dapagliflozin 10 mg-treated patients. Increase in Low-Density Lipoprotein Cholesterol In the pool of 13 placebo-controlled trials of glycemic control, changes from baseline in mean lipid values were reported in dapagliflozin-treated adult patients compared to placebo-treated patients. Mean percent changes from baseline at Week 24 were 0.0% versus 2.5% for total cholesterol, and -1.0% versus 2.9% for LDL cholesterol in the placebo and dapagliflozin 10 mg groups, respectively. In the DECLARE trial [see Clinical Studies (14.3) ] , mean changes from baseline after 4 years were 0.4 mg/dL versus 4.1 mg/dL for total cholesterol, and -2.5 mg/dL versus -4.4 mg/dL for LDL cholesterol, in dapagliflozin-treated and the placebo groups, respectively. Decrease in Serum Bicarbonate In a trial of concomitant therapy of dapagliflozin 10 mg with exenatide extended-release (on a background of metformin) in adults, four patients (1.7%) on concomitant therapy had a serum bicarbonate value of less than or equal to 13 mEq/L compared to one each (0.4%) in the dapagliflozin and exenatide-extended release treatment groups [see Warnings and Precautions (5.1) ]. Clinical Trial in Pediatric Patients with Type 2 Diabetes Mellitus The dapagliflozin safety profile observed in a 26-week placebo-controlled clinical trial with a 26-week extension in 157 pediatric patients aged 10 years and older with type 2 diabetes mellitus was similar to that observed in adults [see Clinical Studies (14.2) ]. 6.2 Postmarketing Experience Additional adverse reactions have been identified during post-approval use of dapagliflozin in patients with diabetes mellitus. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Infections: Necrotizing fasciitis of the perineum (Fournier’s Gangrene), urosepsis and pyelonephritis Metabolism and Nutrition Disorders: Ketoacidosis Renal and Urinary Disorders: Acute kidney injury Skin and Subcutaneous Tissue Disorders: Rash

Table 4: Clinically Relevant Interactions with DAPAGLIFLOZIN TABLETS Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when DAPAGLIFLOZIN TABLETS are 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 DAPAGLIFLOZIN TABLETS 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 DAPAGLIFLOZIN TABLETS with laboratory tests. (7) Drug Interactions In Vitro Assessment of Drug Interactions In in vitro studies, dapagliflozin and dapagliflozin 3-O-glucuronide neither inhibited CYP 1A2, 2C9, 2C19, 2D6, or 3A4, nor induced CYP 1A2, 2B6, or 3A4. Dapagliflozin is a weak substrate of the P-glycoprotein (P-gp) active transporter, and dapagliflozin 3-O-glucuronide is a substrate for the OAT3 active transporter. Dapagliflozin or dapagliflozin 3-O-glucuronide did not meaningfully inhibit P-gp, OCT2, OAT1, or OAT3 active transporters. Overall, dapagliflozin is unlikely to affect the pharmacokinetics of concurrently administered medications that are P-gp, OCT2, OAT1, or OAT3 substrates. Effects of Other Drugs on Dapagliflozin Table 5 shows the effect of coadministered drugs on the pharmacokinetics of dapagliflozin in adults. No dose adjustments are recommended for dapagliflozin.
