5 WARNINGS AND PRECAUTIONS Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis: Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue STEGLATRO if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. ( 5.1 ) Lower Limb Amputation: Monitor patients for infections or ulcers of lower limbs, and institute appropriate treatment. ( 5.2 ) Volume Depletion: May result in acute kidney injury. Before initiating, assess and correct volume status in patients with renal impairment or low systolic blood pressure, elderly patients, or patients on diuretics. Monitor for signs and symptoms during therapy. ( 5.3 ) Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene), and Genital Mycotic Infections: Monitor patients for signs and symptoms of genitourinary infections and treat promptly, if indicated. Immediately evaluate patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, for necrotizing fasciitis and if suspected, discontinue STEGLATRO, and promptly institute appropriate medical and/or surgical intervention. ( 5.4 ) Hypoglycemia: Consider a lower dose of insulin or insulin secretagogue to reduce risk of hypoglycemia when used in combination. ( 5.5 )

5.1 Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, STEGLATRO significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond the background rate. In placebo-controlled trials of patients with type 1 diabetes mellitus, the risk of ketoacidosis was markedly increased in patients who received sodium glucose transporter 2 (SGLT2) inhibitors compared to patients who received placebo; this risk may be greater with higher doses. STEGLATRO is not indicated for glycemic control in patients with type 1 diabetes mellitus. Type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are also risk factors for ketoacidosis. There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes mellitus using SGLT2 inhibitors. Precipitating conditions for diabetic ketoacidosis or other ketoacidosis include under-insulinization due to insulin dose reduction or missed insulin doses, acute febrile illness, reduced caloric intake, ketogenic diet, surgery, volume depletion, and alcohol abuse. Signs and symptoms are consistent with dehydration and severe metabolic acidosis and include nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. Blood glucose levels at presentation may be below those typically expected for diabetic ketoacidosis (e.g., less than 250 mg/dL). Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 4 days after discontinuing STEGLATRO [see Clinical Pharmacology (12.2) ]; however, there have been postmarketing reports of ketoacidosis and/or glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Consider ketone monitoring in patients at risk for ketoacidosis if indicated by the clinical situation. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue STEGLATRO, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting STEGLATRO. Withhold STEGLATRO, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume STEGLATRO when the patient is clinically stable and has resumed oral intake [see Dosage and Administration (2.3) ]. Educate all patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue STEGLATRO and seek medical attention immediately if signs and symptoms occur.

5.2 Lower Limb Amputation In a long-term cardiovascular outcomes study, in patients with type 2 diabetes mellitus and established cardiovascular disease, the occurrence of non-traumatic lower limb amputations was reported with event rates of 4.7, 5.7, and 6.0 events per 1,000 patient-years in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg treatment arms, respectively [see Adverse Reactions (6.1) and Clinical Studies (14.2) ] . Amputation of the toe and foot were most frequent (81 out of 109 patients with lower limb amputations). Some patients had multiple amputations, some involving both lower limbs. Lower limb infections, gangrene, and diabetic foot ulcers were the most common precipitating medical events leading to the need for an amputation. Patients with amputations were more likely to be male, have higher A1C (%) at baseline, have a history of peripheral arterial disease, amputation or peripheral revascularization procedure, diabetic foot, and to have been taking diuretics or insulin. Counsel patients about the importance of routine preventative foot care. Monitor patients receiving STEGLATRO for signs and symptoms of infection (including osteomyelitis), new pain or tenderness, sores or ulcers involving the lower limbs, and institute appropriate treatment.

5.3 Volume Depletion STEGLATRO can cause intravascular volume contraction which may sometimes manifest as symptomatic hypotension or acute transient changes in creatinine [see Adverse Reactions (6.1) ] . There have been postmarketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients with type 2 diabetes mellitus receiving SGLT2 inhibitors, including STEGLATRO. Patients with impaired renal function (eGFR less than 60 mL/min/1.73 m 2 ) [see Use in Specific Populations (8.6) ] , elderly patients, patients with low systolic blood pressure, or patients on loop diuretics may be at increased risk for volume depletion or hypotension. Before initiating STEGLATRO in patients with one or more of these characteristics, assess volume status and renal function. In patients with volume depletion, correct this condition before initiating STEGLATRO. Monitor for signs and symptoms of volume depletion, and renal function after initiating therapy.

5.4 Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene), and Genital Mycotic Infections STEGLATRO increases urinary glucose excretion [see Clinical Pharmacology (12.2) ] and increases the risk of genitourinary infections including urinary tract infections and genital mycotic infections in both male and female patients [see Adverse Reactions (6.1) ]. Serious genitourinary infections, including urosepsis, pyelonephritis, and necrotizing fasciitis of the perineum (Fournier’s gangrene, a rare life-threatening infection requiring urgent surgical intervention), have occurred in patients receiving SGLT2 inhibitors [see Adverse Reactions (6.2) ]. Cases have required hospitalization. In patients with Fournier’s gangrene, serious outcomes have included multiple surgeries and death. Patients with a history of genitourinary infections are more likely to develop genitourinary infections when using STEGLATRO. Monitor patients for signs and symptoms of genitourinary infections and treat promptly, if indicated. Immediately evaluate patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, for necrotizing fasciitis. If suspected, discontinue STEGLATRO and promptly institute appropriate medical and/or surgical intervention.

5.5 Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues Insulin and insulin secretagogues (e.g., sulfonylurea) are known to cause hypoglycemia. STEGLATRO may increase the risk of hypoglycemia when used in combination with insulin or an insulin secretagogue [see Adverse Reactions (6.1) ] . The risk of hypoglycemia may be lowered by a reduction in the dose of insulin or sulfonylurea (or other concomitantly administered insulin secretagogues). Inform patients using these medications concomitantly of this risk and educate them on the signs and symptoms of hypoglycemia.

The following important adverse reactions are described elsewhere in the labeling: Diabetic Ketoacidosis in Patients with Type 1 Diabetes and Other Ketoacidosis [see Warnings and Precautions (5.1) ] Lower Limb Amputation [see Warnings and Precautions (5.2) ] Volume Depletion [see Warnings and Precautions (5.3) ] Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene), and Genital Mycotic Infections [see Warnings and Precautions (5.4) ] Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues [see Warnings and Precautions (5.5) ] Most common adverse reactions (incidence ≥ 5%) were female genital mycotic infections.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Pool of Placebo-Controlled Trials Evaluating STEGLATRO 5 and 15 mg The data in Table 1 are derived from a pool of three 26-week, placebo-controlled trials. STEGLATRO was used as monotherapy in one trial and as add-on therapy in two trials [see Clinical Studies (14) ] . These data reflect exposure of 1,029 patients to STEGLATRO with a mean exposure duration of approximately 25 weeks. Patients received STEGLATRO 5 mg (N=519), STEGLATRO 15 mg (N=510), or placebo (N=515) once daily. The mean age of the population was 57 years and 2% were older than 75 years of age. Fifty-three percent (53%) of the population was male and 73% were White, 15% were Asian, and 7% were Black or African American. At baseline the population had diabetes for an average of 7.5 years, had a mean HbA1c of 8.1%, and 19.4% had established microvascular complications of diabetes. Baseline renal function (mean eGFR 88.9 mL/min/1.73 m 2 ) was normal or mildly impaired in 97% of patients and moderately impaired in 3% of patients. Table 1 shows common adverse reactions associated with the use of STEGLATRO. These adverse reactions were not present at baseline, occurred more commonly on STEGLATRO than on placebo, and occurred in at least 2% of patients treated with either STEGLATRO 5 mg or STEGLATRO 15 mg. Table 1: Adverse Reactions Reported in ≥2% of Patients with Type 2 Diabetes Mellitus Treated with STEGLATRO The three placebo-controlled studies included one monotherapy trial and two add-on combination trials with metformin HCl or with metformin HCl and sitagliptin. and Greater than Placebo in Pooled Placebo-Controlled Clinical Studies of STEGLATRO Monotherapy or Combination Therapy Number (%) of Patients Placebo N = 515 STEGLATRO 5 mg N = 519 STEGLATRO 15 mg N = 510 Female genital mycotic infections Includes: genital candidiasis, genital infection fungal, vaginal infection, vulvitis, vulvovaginal candidiasis, vulvovaginal mycotic infection, and vulvovaginitis. Percentages calculated with the number of female patients in each group as denominator: placebo (N=235), STEGLATRO 5 mg (N=252), STEGLATRO 15 mg (N=245). 3.0% 9.1% 12.2% Male genital mycotic infections Includes: balanitis candida, balanoposthitis, genital infection, and genital infection fungal. Percentages calculated with the number of male patients in each group as denominator: placebo (N=280), STEGLATRO 5 mg (N=267), STEGLATRO 15 mg (N=265). 0.4% 3.7% 4.2% Urinary tract infections Includes: cystitis, dysuria, streptococcal urinary tract infection, urethritis, urinary tract infection. 3.9% 4.0% 4.1% Headache 2.3% 3.5% 2.9% Vaginal pruritus Includes: vulvovaginal pruritus and pruritus genital. Percentages calculated with the number of female patients in each group as denominator: placebo (N=235), ertugliflozin 5 mg (N=252), ertugliflozin 15 mg (N=245). 0.4% 2.8% 2.4% Increased urination Includes: pollakiuria, micturition urgency, polyuria, urine output increased, and nocturia. 1.0% 2.7% 2.4% Nasopharyngitis 2.3% 2.5% 2.0% Back pain 2.3% 1.7% 2.5% Weight decreased 1.0% 1.2% 2.4% Thirst Includes: thirst, dry mouth, polydipsia, and dry throat. 0.6% 2.7% 1.4% Volume Depletion STEGLATRO causes an osmotic diuresis, which may lead to intravascular volume contraction and adverse reactions related to volume depletion, particularly in patients with impaired renal function (eGFR less than 60 mL/min/1.73 m 2 ). In patients with moderate renal impairment, adverse reactions related to volume depletion (e.g., dehydration, dizziness postural, presyncope, syncope, hypotension, and orthostatic hypotension) were reported in 0%, 4.4%, and 1.9% of patients treated with placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively. STEGLATRO may also increase the risk of hypotension in other patients at risk for volume contraction [see Use in Specific Populations (8.5 , 8.6) ] . Hypoglycemia The incidence of hypoglycemia by study is shown in Table 2 . Table 2: Incidence of Overall Overall hypoglycemic events: plasma or capillary glucose of less than or equal to 70 mg/dL. and Severe Severe hypoglycemic events: required assistance, lost consciousness, or experienced a seizure regardless of blood glucose. Hypoglycemia in Placebo-Controlled Clinical Studies in Patients with Type 2 Diabetes Mellitus Monotherapy (26 weeks) Placebo (N = 153) STEGLATRO 5 mg (N =156) STEGLATRO 15 mg (N = 152) Overall [N (%)] 1 (0.7) 4 (2.6) 4 (2.6) Severe [N (%)] 0 (0.0) 0 (0.0) 2 (1.3) Add-on Combination Therapy with Metformin HCl (26 weeks) Placebo (N = 209) STEGLATRO 5 mg (N = 207) STEGLATRO 15 mg (N = 205) Overall [N (%)] 9 (4.3) 15 (7.2) 16 (7.8) Severe [N (%)] 1 (0.5) 1 (0.5) 0 (0.0) Add-on Combination Therapy with Metformin HCl and Sitagliptin (26 weeks) Placebo (N = 153) STEGLATRO 5 mg (N = 156) STEGLATRO 15 mg (N = 153) Overall [N (%)] 5 (3.3) 7 (4.5) 3 (2.0) Severe [N (%)] 1 (0.7) 1 (0.6) 0 (0.0) In Combination with Insulin and/or an Insulin Secretagogue in Patients with Moderate Renal Impairment (26 weeks) Placebo (N = 133) STEGLATRO 5 mg (N = 148) STEGLATRO 15 mg (N = 143) Overall [N (%)] 48 (36.1) 53 (35.8) 39 (27.3) Severe [N (%)] 3 (2.3) 5 (3.4) 3 (2.1) Add-on Combination with Insulin with or without Metformin HCl (18 weeks) Placebo (N = 347) STEGLATRO 5 mg (N = 348) STEGLATRO 15 mg (N = 370) Overall [N (%)] 130 (37.5) 137 (39.4) 144 (38.9) Severe [N (%)] 12 (3.5) 13 (3.7) 19 (5.1) Add-on Combination with a Sulfonylurea (18 weeks) Placebo (N =48) STEGLATRO 5 mg (N =55) STEGLATRO 15 mg (N =54) Overall [N (%)] 2 (4.2) 4 (7.3) 5 (9.3) Severe [N (%)] 0 (0.0) 0 (0.0) 0 (0.0) Add-on Combination with Metformin HCl and a Sulfonylurea (18 weeks) Placebo (N = 117) STEGLATRO 5 mg (N = 100) STEGLATRO 15 mg (N = 113) Overall [N (%)] 17 (14.5) 20 (20.0) 30 (26.5) Severe [N (%)] 1 (0.9) 2 (2.0) 2 (1.8) Lower Limb Amputation In a long-term cardiovascular outcomes study [see Clinical Studies (14.2) ] , in patients with type 2 diabetes mellitus and established cardiovascular disease, the occurrence of non-traumatic lower limb amputations was reported with event rates of 4.7, 5.7, and 6.0 events per 1,000 patient-years in the placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg treatment arms, respectively. Across seven STEGLATRO clinical trials, non-traumatic lower limb amputations were reported in 1 (0.1%) patient in the comparator group, 3 (0.2%) patients in the STEGLATRO 5 mg group, and 8 (0.5%) patients in the STEGLATRO 15 mg group. Genital Mycotic Infections In the pool of three placebo-controlled clinical trials, the incidence of female genital mycotic infections (e.g., genital candidiasis, genital infection fungal, vaginal infection, vulvitis, vulvovaginal candidiasis, vulvovaginal mycotic infection, vulvovaginitis) occurred in 3%, 9.1%, and 12.2% of females treated with placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively (see Table 1 ). In females, discontinuation due to genital mycotic infections occurred in 0% and 0.6% of patients treated with placebo and STEGLATRO, respectively. In the same pool, male genital mycotic infections (e.g., balanitis candida, balanoposthitis, genital infection, genital infection fungal) occurred in 0.4%, 3.7%, and 4.2% of males treated with placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively (see Table 1 ). Male genital mycotic infections occurred more commonly in uncircumcised males. In males, discontinuations due to genital mycotic infections occurred in 0% and 0.2% of patients treated with placebo and STEGLATRO, respectively. Phimosis was reported in 8 of 1729 (0.5%) male ertugliflozin-treated patients, of which four required circumcision. Urinary Tract Infections In VERTIS CV, urinary tract infections (e.g., urinary tract infection, cystitis, dysuria) occurred in 10.2%, 12.2% and 12.0% of patients treated with placebo, STEGLATRO 5 mg and STEGLATRO 15 mg, respectively. The incidences of serious urinary tract infections were 0.8%, 0.9% and 0.4% with placebo, STEGLATRO 5 mg and STEGLATRO 15 mg, respectively. Laboratory Tests Changes in Serum Creatinine and eGFR Initiation of STEGLATRO causes an increase in serum creatinine and decrease in eGFR within weeks of starting therapy and then these changes stabilize. In a study of patients with moderate renal impairment, larger mean changes were observed. In a long-term cardiovascular outcomes trial, an initial increase in serum creatinine and a decrease in eGFR within weeks of starting therapy was observed (at Week 6 eGFR changes of -2.7, -3.8 and -0.4 mL/min/1.73 m 2 in the STEGLATRO 5 mg, STEGLATRO 15 mg and placebo arms, respectively). The initial decline was followed by a recovery toward baseline to Week 52 (eGFR change from baseline of - 0.4, - 1.1 and - 0.2 mL/min/1.73 m 2 in STEGLATRO 5 mg, STEGLATRO 15 mg, and placebo arms, respectively). Acute hemodynamic changes may play a role in the early renal function changes observed with STEGLATRO since they are reversed after treatment discontinuation. Increases in Low-Density Lipoprotein Cholesterol (LDL-C) In the pool of three placebo-controlled trials, dose-related increases in LDL-C were observed in patients treated with STEGLATRO. Mean percent changes from baseline to Week 26 in LDL-C relative to placebo were 2.6% and 5.4% with STEGLATRO 5 mg and STEGLATRO 15 mg, respectively. The range of mean baseline LDL-C was 96.6 to 97.7 mg/dL across treatment groups. Increases in Hemoglobin In the pool of three placebo-controlled trials, mean changes (percent changes) from baseline to Week 26 in hemoglobin were -0.21 g/dL (-1.4%) with placebo, 0.46 g/dL (3.5%) with STEGLATRO 5 mg, and 0.48 g/dL (3.5%) with STEGLATRO 15 mg. The range of mean baseline hemoglobin was 13.90 to 14.00 g/dL across treatment groups. At the end of treatment, 0.0%, 0.2%, and 0.4% of patients treated with placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively, had a hemoglobin increase greater than 2 g/dL and above the upper limit of normal. Increases in Serum Phosphate In the pool of three placebo-controlled trials, mean changes (percent changes) from baseline in serum phosphate were 0.04 mg/dL (1.9%) with placebo, 0.21 mg/dL (6.8%) with STEGLATRO 5 mg, and 0.26 mg/dL (8.5%) with STEGLATRO 15 mg. The range of mean baseline serum phosphate was 3.53 to 3.54 mg/dL across treatment groups. In a clinical trial of patients with moderate renal impairment, mean changes (percent changes) from baseline at Week 26 in serum phosphate were -0.01 mg/dL (0.8%) with placebo, 0.29 mg/dL (9.7%) with STEGLATRO 5 mg, and 0.24 mg/dL (7.8%) with STEGLATRO 15 mg.

6.2 Postmarketing Experience Additional adverse reactions have been identified during postapproval use of STEGLATRO. 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) Skin and Subcutaneous Tissue Disorders: angioedema, rash

Pregnancy: Advise females of the potential risk to a fetus especially during the second and third trimesters. ( 8.1 ) Lactation: Breastfeeding not recommended. ( 8.2 ) Geriatrics: Higher incidence of adverse reactions related to reduced intravascular volume. ( 8.5 ) Renal Impairment: Higher incidence of adverse reactions related to reduced intravascular volume and renal function. ( 8.6 )

8.1 Pregnancy Risk Summary Based on animal data showing adverse renal effects, STEGLATRO is not recommended during the second and third trimesters of pregnancy. The limited available data with STEGLATRO in pregnant women are not sufficient to determine a drug-associated risk of adverse developmental outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations ) . In animal studies, adverse renal changes were observed in rats when ertugliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy. Doses approximately 13 times the maximum clinical dose caused renal pelvic and tubule dilatations and renal mineralization that were not fully reversible. There was no evidence of fetal harm in rats or rabbits at exposures of ertugliflozin approximately 300 times higher than the maximal clinical dose of 15 mg/day when administered during organogenesis (see Data ) . The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with a HbA1c >7 and has been reported to be as high as 20-25% in women with HbA1c >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 2-4% and 15-20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, 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 When ertugliflozin was orally administered to juvenile rats from PND 21 to PND 90, increased kidney weight, renal tubule and renal pelvis dilatation, and renal mineralization occurred at doses greater than or equal to 5 mg/kg (13-fold human exposures, based on AUC). These effects occurred with drug exposure during periods of renal development in rats that correspond to the late second and third trimester of human renal development, and did not fully reverse within a 1-month recovery period. In embryo-fetal development studies, ertugliflozin (50, 100 and 250 mg/kg/day) was administered orally to rats on gestation days 6 to 17 and to rabbits on gestation days 7 to 19. Ertugliflozin did not adversely affect developmental outcomes in rats and rabbits at maternal exposures that were approximately 300 times the human exposure at the maximum clinical dose of 15 mg/day, based on AUC. A maternally toxic dose (250 mg/kg/day) in rats (707 times the clinical dose), was associated with reduced fetal viability, and a higher incidence of a visceral malformation (membranous ventricular septal defect). In the pre- and post-natal development study in pregnant rats, ertugliflozin was administered to the dams from gestation day 6 through lactation day 21 (weaning). Decreased post-natal growth (weight gain) was observed at maternal doses ≥100 mg/kg/day (greater than or equal to 331 times the human exposure at the maximum clinical dose of 15 mg/day, based on AUC).

8.2 Lactation Risk Summary There is no information regarding the presence of STEGLATRO in human milk, the effects on the breastfed infant, or the effects on milk production. Ertugliflozin is present in the milk of lactating rats (see Data ) . 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 a breastfed infant, advise women that the use of STEGLATRO is not recommended while breastfeeding. Data The lacteal excretion of radiolabeled ertugliflozin in lactating rats was evaluated 10 to 12 days after parturition. Ertugliflozin derived radioactivity exposure in milk and plasma were similar, with a milk/plasma ratio of 1.07, based on AUC. Juvenile rats directly exposed to STEGLATRO during a developmental period corresponding to human kidney maturation were associated with a risk to the developing kidney (persistent increased organ weight, renal mineralization, and renal pelvic and tubular dilatations).

8.4 Pediatric Use Safety and effectiveness of STEGLATRO in pediatric patients under 18 years of age have not been established.

8.5 Geriatric Use No dosage adjustment of STEGLATRO is recommended based on age. In STEGLATRO clinical trials, a total of 876 (25.7%) patients treated with STEGLATRO were 65 years and older, and 152 (4.5%) patients treated with STEGLATRO were 75 years and older. Patients 65 years and older had a higher incidence of adverse reactions related to volume depletion compared to younger patients; events were reported in 1.1%, 2.2%, and 2.6% of patients treated with comparator, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively [see Warnings and Precautions (5.3) and Adverse Reactions (6.1) ] . In VERTIS CV, a total of 2780 (50.5%) patients treated with STEGLATRO were 65 years and older, and 595 (10.8%) patients treated with STEGLATRO were 75 years and older. Safety and efficacy were generally similar for patients age 65 years and older compared to patients younger than 65.

8.6 Renal Impairment A 26-week placebo-controlled study of 313 patients with Stage 3 Chronic Kidney Disease (eGFR ≥30 to less than 60 mL/min/1.73 m 2 ) treated with STEGLATRO did not demonstrate improvement in glycemic control. In the VERTIS CV study, there were 1370 patients (25%) with an eGFR ≥90 mL/min/1.73 m 2 , 2929 patients (53%) with an eGFR of ≥60 to less than 90 mL/min/1.73 m 2 , 879 patients (16%) with an eGFR of ≥45 to less than 60 mL/min/1.73 m 2 , and 299 patients (5%) with eGFR of 30 to <45 mL/min/1.73 m 2 treated with STEGLATRO. Similar effects on glycemic control at Week 18 were observed in patients treated with STEGLATRO in each eGFR subgroup and also in the overall patient population. No dosage adjustment is needed in patients with eGFR ≥45 mL/min/1.73 m 2 .

8.7 Hepatic Impairment No dosage adjustment of STEGLATRO is necessary in patients with mild or moderate hepatic impairment. Ertugliflozin has not been studied in patients with severe hepatic impairment and is not recommended for use in this patient population [see Clinical Pharmacology (12.3) ] .

12.1 Mechanism of Action SGLT2 is the predominant transporter responsible for reabsorption of glucose from the glomerular filtrate back into the circulation. Ertugliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, ertugliflozin reduces renal reabsorption of filtered glucose and lowers the renal threshold for glucose, and thereby increases urinary glucose excretion.

12.2 Pharmacodynamics Urinary Glucose Excretion and Urinary Volume Dose-dependent increases in the amount of glucose excreted in urine were observed in healthy subjects and in patients with type 2 diabetes mellitus following single- and multiple-dose administration of ertugliflozin. Dose-response modeling indicates that ertugliflozin 5 mg and 15 mg result in near maximal urinary glucose excretion (UGE). Enhanced UGE is maintained after multiple-dose administration. UGE with ertugliflozin also results in increases in urinary volume. Cardiac Electrophysiology The effect of STEGLATRO on QTc interval was evaluated in a Phase 1 randomized, placebo- and positive-controlled 3-period crossover study in 42 healthy subjects. At 6.7 times the therapeutic exposures with maximum recommended dose, STEGLATRO does not prolong QTc to any clinically relevant extent.

12.3 Pharmacokinetics The pharmacokinetics of ertugliflozin are similar in healthy subjects and patients with type 2 diabetes mellitus. The steady state mean plasma AUC and C max were 398 ng∙hr/mL and 81.3 ng/mL, respectively, with 5 mg ertugliflozin once-daily treatment, and 1,193 ng∙hr/mL and 268 ng/mL, respectively, with 15 mg ertugliflozin once-daily treatment. Steady-state is reached after 4 to 6 days of once-daily dosing with ertugliflozin. Ertugliflozin does not exhibit time-dependent pharmacokinetics and accumulates in plasma up to 10-40% following multiple dosing. Absorption Following single-dose oral administration of 5 mg and 15 mg of ertugliflozin, peak plasma concentrations (median T max ) of ertugliflozin occur at 1 hour postdose under fasted conditions. Plasma C max and AUC of ertugliflozin increase in a dose-proportional manner following single doses from 0.5 mg (0.1 times the lowest recommended dose) to 300 mg (20 times the highest recommended dose) and following multiple doses from 1 mg (0.2 times the lowest recommended dose) to 100 mg (6.7 times the highest recommended dose). The absolute oral bioavailability of ertugliflozin following administration of a 15 mg dose is approximately 100%. Effect of Food Administration of STEGLATRO with a high-fat and high-calorie meal decreases ertugliflozin C max by 29% and prolongs T max by 1 hour, but does not alter AUC as compared with the fasted state. The observed effect of food on ertugliflozin pharmacokinetics is not considered clinically relevant, and ertugliflozin may be administered with or without food. In Phase 3 clinical trials, STEGLATRO was administered without regard to meals. Distribution The mean steady-state volume of distribution of ertugliflozin following an intravenous dose is 85.5 L. Plasma protein binding of ertugliflozin is 93.6% and is independent of ertugliflozin plasma concentrations. Plasma protein binding is not meaningfully altered in patients with renal or hepatic impairment. The blood-to-plasma concentration ratio of ertugliflozin is 0.66. Elimination Metabolism Metabolism is the primary clearance mechanism for ertugliflozin. The major metabolic pathway for ertugliflozin is UGT1A9 and UGT2B7-mediated O-glucuronidation to two glucuronides that are pharmacologically inactive at clinically relevant concentrations. CYP-mediated (oxidative) metabolism of ertugliflozin is minimal (12%). Excretion The mean systemic plasma clearance following an intravenous 100 µg dose was 11.2 L/hr. The mean elimination half-life in type 2 diabetic patients with normal renal function was estimated to be 16.6 hours based on the population pharmacokinetic analysis. Following administration of an oral [ 14 C]-ertugliflozin solution to healthy subjects, approximately 40.9% and 50.2% of the drug-related radioactivity was eliminated in feces and urine, respectively. Only 1.5% of the administered dose was excreted as unchanged ertugliflozin in urine and 33.8% as unchanged ertugliflozin in feces, which is likely due to biliary excretion of glucuronide metabolites and subsequent hydrolysis to parent. Specific Populations Patients with Renal Impairment In a clinical pharmacology study in patients with type 2 diabetes mellitus and mild, moderate, or severe renal impairment (as determined by eGFR), following a single-dose administration of 15 mg STEGLATRO, the mean increases in AUC of ertugliflozin were 1.6-, 1.7-, and 1.6-fold, respectively, for mild, moderate and severe renally impaired patients, compared to subjects with normal renal function. These increases in ertugliflozin AUC are not considered clinically meaningful. The 24-hour urinary glucose excretion declined with increasing severity of renal impairment [see Warnings and Precautions (5.3) and Use in Specific Populations (8.6) ] . The plasma protein binding of ertugliflozin was unaffected in patients with renal impairment. Patients with Hepatic Impairment Moderate hepatic impairment (based on the Child-Pugh classification) did not result in an increase in exposure of ertugliflozin. The AUC of ertugliflozin decreased by approximately 13%, and C max decreased by approximately 21% compared to subjects with normal hepatic function. This decrease in ertugliflozin exposure is not considered clinically meaningful. There is no clinical experience in patients with Child-Pugh class C (severe) hepatic impairment. The plasma protein binding of ertugliflozin was unaffected in patients with moderate hepatic impairment [see Use in Specific Populations (8.7) ]. Effects of Age, Body Weight, Gender, and Race Based on a population pharmacokinetic analysis, age, body weight, gender, and race do not have a clinically meaningful effect on the pharmacokinetics of ertugliflozin. Drug Interaction Studies In Vitro Assessment of Drug Interactions In in vitro studies, ertugliflozin and ertugliflozin glucuronides did not inhibit CYP450 isoenzymes (CYPs) 1A2, 2C9, 2C19, 2C8, 2B6, 2D6, or 3A4, and did not induce CYPs 1A2, 2B6, or 3A4. Ertugliflozin was not a time-dependent inhibitor of CYP3A in vitro . Ertugliflozin did not inhibit UGT1A6, 1A9, or 2B7 in vitro and was a weak inhibitor (IC 50 >39 µM) of UGT1A1 and 1A4. Ertugliflozin glucuronides did not inhibit UGT1A1, 1A4, 1A6, 1A9, or 2B7 in vitro . Overall, ertugliflozin is unlikely to affect the pharmacokinetics of drugs eliminated by these enzymes. Ertugliflozin is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) transporters and is not a substrate of organic anion transporters (OAT1, OAT3), organic cation transporters (OCT1, OCT2), or organic anion transporting polypeptides (OATP1B1, OATP1B3). Ertugliflozin or ertugliflozin glucuronides do not meaningfully inhibit P-gp, OCT2, OAT1, or OAT3 transporters, or transporting polypeptides OATP1B1 and OATP1B3, at clinically relevant concentrations. Overall, ertugliflozin is unlikely to affect the pharmacokinetics of concurrently administered medications that are substrates of these transporters. In Vivo Assessment of Drug Interactions No dose adjustment of STEGLATRO is recommended when coadministered with commonly prescribed medicinal products. Ertugliflozin pharmacokinetics were similar with and without coadministration of metformin, glimepiride, sitagliptin, and simvastatin in healthy subjects (see Figure 1 ). Coadministration of ertugliflozin with multiple doses of 600 mg once-daily rifampin (an inducer of UGT and CYP enzymes) resulted in approximately 39% and 15% mean reductions in ertugliflozin AUC and C max , respectively, relative to ertugliflozin administered alone. These changes in exposure are not considered clinically relevant. Ertugliflozin had no clinically relevant effect on the pharmacokinetics of metformin, glimepiride, sitagliptin, and simvastatin when coadministered in healthy subjects (see Figure 2 ). Physiologically-based PK (PBPK) modeling suggests that coadministration of mefenamic acid (UGT inhibitor) may increase the AUC and C max of ertugliflozin by 1.51- and 1.19-fold, respectively. These predicted changes in exposure are not considered clinically relevant.

The pharmacokinetics of ertugliflozin are similar in healthy subjects and patients with type 2 diabetes mellitus. The steady state mean plasma AUC and C max were 398 ng∙hr/mL and 81.3 ng/mL, respectively, with 5 mg ertugliflozin once-daily treatment, and 1,193 ng∙hr/mL and 268 ng/mL, respectively, with 15 mg ertugliflozin once-daily treatment. Steady-state is reached after 4 to 6 days of once-daily dosing with ertugliflozin. Ertugliflozin does not exhibit time-dependent pharmacokinetics and accumulates in plasma up to 10-40% following multiple dosing. Absorption Following single-dose oral administration of 5 mg and 15 mg of ertugliflozin, peak plasma concentrations (median T max ) of ertugliflozin occur at 1 hour postdose under fasted conditions. Plasma C max and AUC of ertugliflozin increase in a dose-proportional manner following single doses from 0.5 mg (0.1 times the lowest recommended dose) to 300 mg (20 times the highest recommended dose) and following multiple doses from 1 mg (0.2 times the lowest recommended dose) to 100 mg (6.7 times the highest recommended dose). The absolute oral bioavailability of ertugliflozin following administration of a 15 mg dose is approximately 100%. Effect of Food Administration of STEGLATRO with a high-fat and high-calorie meal decreases ertugliflozin C max by 29% and prolongs T max by 1 hour, but does not alter AUC as compared with the fasted state. The observed effect of food on ertugliflozin pharmacokinetics is not considered clinically relevant, and ertugliflozin may be administered with or without food. In Phase 3 clinical trials, STEGLATRO was administered without regard to meals. Distribution The mean steady-state volume of distribution of ertugliflozin following an intravenous dose is 85.5 L. Plasma protein binding of ertugliflozin is 93.6% and is independent of ertugliflozin plasma concentrations. Plasma protein binding is not meaningfully altered in patients with renal or hepatic impairment. The blood-to-plasma concentration ratio of ertugliflozin is 0.66.
