( 1 ) Limitation of Use: Not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus. ( 1 )

2 DOSAGE AND ADMINISTRATION • Recommended dose: 20 mg once daily, taken in the morning, with or without food. Do not crush or chew the tablet. ( 2.2 ) • Assess renal function before initiating BRENZAVVY and as clinically indicated. Correct volume depletion before initiating ( 2.1 ) • Not recommended if eGFR less than 30 mL/min/1.73 m 2 . ( 2.1 ) • Withhold BRENZAVVY for at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting ( 2.3 ). 2.1 Testing Prior to Initiation and During Treatment with BRENZAVVY • Assess renal function prior to initiation of BRENZAVVY and periodically thereafter as clinically indicated [see Warnings and Precautions ( 5.3 )] . BRENZAVVY is not recommended in patients with an eGFR less than 30 mL/min/1.73 m 2 • Assess volume status. In patients with volume depletion, correct this condition before initiating BRENZAVVY [see Warnings and Precautions ( 5.3 ), Use in Specific Populations ( 8.5 , 8.6 )]. 2.2 Recommended Dosage • The recommended dosage of BRENZAVVY is 20 mg orally taken once daily in the morning, with or without food [see Clinical Pharmacology ( 12.3 )] . • Do not crush or chew the tablet. • If a dose is missed, take the missed dose as soon as possible. Do not double the next dose. 2.3 Temporary Interruption for Surgery • Withhold BRENZAVVY for at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting. Resume BRENZAVVY when the patient is clinically stable and has resumed oral intake [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.2 )] .

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 BRENZAVVY if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. ( 5.1 ) Lower limb amputation: Consider factors that may increase the risk for amputations before initiating BRENZAVVY. Monitor patients for signs and symptoms of infection, or ulcers of the lower limbs, and discontinue if these occur ( 5.2 ) . Volume depletion: May result in acute kidney injury. Before initiating BRENZAVVY, assess and correct volume status in patients with impaired renal function 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 BRENZAVVY, 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 with BRENZAVVY ( 5.5 ) 5.1 Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, BRENZAVVY significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond 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. BRENZAVVY 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 3 days after discontinuing BRENZAVVY [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 BRENZAVVY, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting BRENZAVVY. Withhold BRENZAVVY, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume BRENZAVVY w…

4 CONTRAINDICATIONS BRENZAVVY is contraindicated in patients: With hypersensitivity to bexagliflozin or any excipient in BRENZAVVY. Anaphylaxis and angioedema have been reported with sodium-glucose co-transporter 2 (SGLT2) inhibitors. • Hypersensitivity to bexagliflozin or any excipient in BRENZAVVY

7 DRUG INTERACTIONS See Table 4 for clinically significant interactions with BRENZAVVY. Table 4. Clinically Significant Interactions with BRENZAVVY UGT Enzyme Inducers Clinical Impact UGT Enzyme Inducers may significantly reduce exposure to BRENZAVVY and lead to a decreased efficacy [ see Clinical Pharmacology ( 12.3 )]. Intervention Consider adding another antihyperglycemic agent in patients who require additional glycemic control. Concomitant Use with Insulin and Insulin Secretagogues Clinical Impact The risk of hypoglycemia is increased when BRENZAVVY is used in combination with insulin and/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 BRENZAVVY. Lithium Clinical Impact Concomitant use with SGLT2 inhibitors such as BRENZAVVY may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently upon BRENZAVVY initiation and discontinuation. 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.

8.1 Pregnancy Risk Summary Based on animal data showing adverse renal effects, BRENZAVVY is not recommended during the second and third trimesters of pregnancy. The available data on use of BRENZAVVY during pregnancy are insufficient to determine a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations ) . In animal studies, adverse renal pelvic and tubule dilatations that were not fully reversible were observed in rats when bexagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy at exposures 11 times the 20 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 peri-conceptional HbA1c > 7% and has been reported to be as high as 20% to 25% in women with a peri-conceptional 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% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Hypoglycemia and hyperglycemia occur more frequently during pregnancy in patients with pre-gestational diabetes. 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 Bexagliflozin administered to juvenile rats at 0.3, 3 or 30 mg/kg/day by oral gavage from postnatal days 21 to 90 caused a dose dependent increase in the incidence and severity of renal pelvic and tubular dilatation at ≥ 3 mg/kg (11 times the clinical dose of 20 mg based on AUC). These outcomes occurred with drug exposure during periods of renal development in rats equivalent to the late second and third trimester of human renal development and did not fully reverse following a 1-month recovery period. In embryofetal development studies in rats and rabbits, bexagliflozin was administered at 7, 40, and 200 mg/kg/day (rats) and 5, 25, and 150 mg/kg/day (rabbits) during organogenesis. No adverse developmental effects were observed in rats at doses up to 200 mg/kg/day (551 times the clinical dose of 20 mg based on AUC). Reduced maternal body weight, embryo lethality, and fetal malformations were observed in rabbits at 150 mg/kg/day (368 times the clinical dose of 20 mg based on AUC). In a prenatal and postnatal development study, bexagliflozin was administered to maternal rats by oral gavage during organogenesis and until weaning at doses of 7, 40, or 200 mg/kg/day. Maternal mortality occurred at ≥ 40 mg/kg (79 times the clinical dose of 20 mg based on AUC), primarily following parturition. Reduced gestational body weight, increased post-implantation loss, and smaller litter size were noted at 200 mg/kg (361 times the clinical dose of 20 mg based on AUC). In the offspring, lower body weight gain and decreased survival were noted at 200 mg/kg, which occurred in the presence of significant maternal toxicity.

6 ADVERSE REACTIONS The following important adverse reactions are described below and elsewhere in the labeling: Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus 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 and Insulin Secretagogues [see Warnings and Precautions ( 5.5 )] Most common adverse reactions (incidence > 5%) are female genital mycotic infections, urinary tract infection and increased urination ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact TheracosBio at 1-855-BRENZAVVY (1-855-273-6928) 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 BRENZAVVY 20 mg The data in Table 1 are derived from three trials in adults with type 2 diabetes mellitus: two 24-week placebo-controlled trials (one as monotherapy and another as add-on to metformin therapy; Trials 1 and 2, respectively) [see Clinical Studies ( 14.2 , 14.3 )] and a 12-week, placebo-controlled, dose-ranging, monotherapy trial (only the data from the 20 mg dosage of BRENZAVVY per day were included in this pool). In these pooled trials, patients received placebo (N = 300) or BRENZAVVY 20 mg (N = 372), once daily. The mean age of the population was 56 years and 5% of the patients were older than 75 years of age. Fifty-seven percent (57%) were male and 45% were White, 38% Asian, 15% Black and 2% other races. At baseline, the mean duration of type 2 diabetes mellitus was 7.7 years and the mean hemoglobin A1c (HbA1c) was 8.2%. Established microvascular complications of type 2 diabetes mellitus at baseline included diabetic nephropathy (0.8%), retinopathy (24%), and peripheral neuropathy (33%). Baseline renal function was eGFR ≥ 60 mL/min/1.73 m 2 in 98% of patients and eGFR 45 to < 60 mL/min/1.73 m 2 in 2% of patients (mean eGFR 92 mL/min/1.73 m 2 ). Table 1 shows common adverse reactions associated with the use of BRENZAVVY in these trials. These adverse reactions occurred more commonly in BRENZAVVY-treated patients than placebo-treated patients, and occurred in at least 2% of BRENZAVVY-treated patients. Table 1.
