6 ADVERSE REACTIONS 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) ] Urosepsis and Pyelonephritis [see Warnings and Precautions (5.4) ] Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues [see Warnings and Precautions (5.5) ] Necrotizing Fasciitis of the Perineum (Fournier's Gangrene) [see Warnings and Precautions (5.6) ] Genital Mycotic Infections [see Warnings and Precautions (5.7) ] Most common adverse reactions (incidence ≥ 5%) were female genital mycotic infections. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme LLC at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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.

Drug Interactions

7 DRUG INTERACTIONS Table 3: Clinically Significant Drug Interactions with STEGLATRO Insulin or Insulin Secretagogues Clinical Impact: The risk of hypoglycemia is increased when STEGLATRO is used in combination with insulin or an insulin secretagogue. Intervention: A lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with STEGLATRO. Lithium Clinical Impact: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention: Monitor serum lithium concentration more frequently during STEGLATRO 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 STEGLATRO with laboratory tests. ( 7 )

Contraindications

4 CONTRAINDICATIONS STEGLATRO is contraindicated in patients with hypersensitivity to ertugliflozin or any excipient in STEGLATRO. Reactions such as angioedema have occurred [see Adverse Reactions (6.2) ]. Hypersensitivity to ertugliflozin or any of the excipients in STEGLATRO. ( 4 )

Pregnancy and Breastfeeding

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...

Overdosage

10 OVERDOSAGE In the event of an overdose with STEGLATRO, contact the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Employ the usual supportive measures as dictated by the patient's clinical status. Removal of ertugliflozin by hemodialysis has not been studied.
