( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Lexicon at 1-855-330-2573 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 clinical practice. In the phase 3 (SOLOIST [see Clinical Studies ( 14.1 )] and SCORED [see Clinical Studies ( 14.2 )] ) placebo-controlled trials, 5,896 subjects received INPEFA. In the SOLOIST study, 336 patients (56%) reached the 400 mg dose. In the SCORED study, 3,934 patients (74%) reached the 400 mg dose. In the SOLOIST study, 5.6% of patients in the INPEFA group and 5.4% of patients in the placebo group discontinued therapy due to adverse events (AEs). In the SCORED study, 5.0% of patients in the INPEFA group and 4.5% of patients in the placebo group discontinued therapy due to AEs.

These changes in serum creatinine and eGFR generally occur within 4 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. In studies that included 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 INPEFA [see Warnings and Precautions ( 5.2 ) and Use in Specific Populations ( 8.6 )] .

4 CONTRAINDICATIONS INPEFA is contraindicated in patients with a history of serious hypersensitivity reaction to INPEFA. History of serious hypersensitivity reaction to INPEFA. ( 4 )

2 DOSAGE AND ADMINISTRATION Correct volume status before starting INPEFA at 200 mg daily and titrate to 400 mg as tolerated. ( 2.2 ) In patients with decompensated heart failure, begin dosing when patients are hemodynamically stable. ( 2.1 ) Withhold INPEFA at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting. ( 2.3 ) 2.1 Prior to Initiation of INPEFA Assess volume status and, if necessary, correct volume depletion prior to initiation of INPEFA [see Warnings and Precautions ( 5.2 ) and Use in Specific Populations ( 8.5 , 8.6 )] . Assess renal function prior to initiation of INPEFA and then as clinically indicated [see Warnings and Precautions ( 5.2 )] . For patients with decompensated heart failure, dosing may begin as soon as the patient is hemodynamically stable, including during hospitalization or urgent outpatient treatment or immediately upon discharge. 2.2 Recommended Dosage The recommended starting dose of INPEFA is 200 mg orally once daily not more than one hour before the first meal of the day. Up-titrate after at least 2 weeks to 400 mg orally once daily as tolerated [see Clinical Studies ( 14 )] . Down-titrate to 200 mg as necessary [see Adverse Reactions ( 6.1 ), Warnings and Precautions ( 5 ) and Use in Specific Populations ( 8.6 )]. Swallow tablets whole. Do not cut, crush, or chew tablets. If a dose of INPEFA is missed by more than 6 hours, take the next dose as prescribed the next day. 2.3 Temporary Interruption for Surgery Withhold INPEFA at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting. Resume INPEFA when the patient is clinically stable and has resumed oral intake [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )] .

1 INDICATIONS AND USAGE INPEFA is indicated to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit in adults with: heart failure or type 2 diabetes mellitus, chronic kidney disease, and other cardiovascular risk factors INPEFA is a sodium-glucose cotransporter 2 (SGLT2) inhibitor indicated to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit in adults with: heart failure ( 1 ) or type 2 diabetes mellitus, chronic kidney disease, and other cardiovascular risk factors ( 1 )

10 OVERDOSAGE There were no confirmed reports of symptomatic overdose with sotagliflozin during the clinical development program of INPEFA. In the event of an overdose with INPEFA, contact the Poison Control Center. Employ the usual supportive measures as dictated by the patient's clinical status. The removal of sotagliflozin by hemodialysis has not been studied.

7 DRUG INTERACTIONS Digoxin : Monitor digoxin levels. ( 7.1 ) Uridine 5'-diphospho-glucuronosyltransferase Inducers (e.g., rifampin): Sotagliflozin exposure is reduced. Consider monitoring of clinical status. ( 7.2 ) Lithium: Monitor serum lithium concentrations. ( 7.3 ) 7.1 Digoxin There is an increase in the exposure of digoxin when coadministered with INPEFA 400 mg. Patients taking INPEFA with concomitant digoxin should be monitored appropriately [see Clinical Pharmacology ( 12.3 )] . 7.2 Uridine 5'-diphospho-glucuronosyltransferase (UGT) Inducer Glucuronidation by UGT1A9, to form the 3-O-glucuronide, was identified as a major metabolic pathway for sotagliflozin. The coadministration of rifampicin, an inducer of UGTs, with a single dose of 400 mg sotagliflozin resulted in a decrease in the exposure to sotagliflozin. This decrease in exposure to sotagliflozin may decrease efficacy [see Clinical Pharmacology ( 12.3 )] . 7.3 Lithium Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Monitor serum lithium concentration more frequently during INPEFA initiation and dosage changes.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Sotagliflozin is an inhibitor of SGLT2 and SGLT1. Inhibiting SGLT2 reduces renal reabsorption of glucose and sodium which may influence several physiological functions such as lowering both pre-and afterload of the heart and downregulating sympathetic activity. Inhibiting SGLT1 reduces intestinal absorption of glucose and sodium which likely contributes to diarrhea. The mechanism for sotagliflozin's cardiovascular benefits has not been established. 12.2 Pharmacodynamics Cardiac Electrophysiology In a randomized, placebo-controlled, active-comparator, crossover study, 58 healthy subjects were administered a single oral dose of sotagliflozin 800 mg or sotagliflozin 2000 mg (5 times the maximum recommended dose), moxifloxacin, and placebo. No increase in QT corrected for heart rate (QTc) was observed with either 800 mg or 2000 mg sotagliflozin. 12.3 Pharmacokinetics Plasma C max and AUC of sotagliflozin increased in a dose-proportional manner in the therapeutic dose range of 200 mg to 400 mg once daily. Accumulation of sotagliflozin was observed with an approximate 50-100% increase in both C max and area under the concentration-time curve from 0 to 24 hours (AUC 0-24h ) at steady state verses the first day of dosing. Absorption The absolute bioavailability of oral sotagliflozin 400 mg dose was approximately 25% (90% confidence interval [CI] 16% to 39%) for area under the concentration-time curve from time 0 to last measurable concentration (AUC 0-last ). The contribution of enterohepatic circulation to the overall exposure is estimated to be approximately 50%. The median time to maximum plasma concentration (T max ) ranged from 1.25 to 3 hours, over a single-dose range of 200 mg to 2000 mg. Following administration of multiple doses (400 mg and 800 mg), the median T max values ranged from 2.5 to 4 hours. Food Effect When sotagliflozin tablets were administered with a high-caloric breakfast compared to fasting conditions, plasma exposure to sotagliflozin as measured by C max and AUC 0-inf increased by 149% and 50%, respectively. Multiple doses of sotagliflozin 400 mg given immediately before breakfast, 30 minutes prior to breakfast, and 1-hour before breakfast in healthy subjects showed a consistent effect of sotagliflozin on urine glucose excretion (UGE), insulin, and postprandial glucose (PPG) across all dose schedules. It is recommended that INPEFA be taken not more than one hour before the first meal of the day. Distribution Both sotagliflozin and its major human metabolite sotagliflozin 3-O-glucuronide exhibited high binding to human plasma proteins in vitro (> 93% bound), which was not dependent on the concentration of sotagliflozin and sotagliflozin 3-O-glucuronide and was not influenced by the degree of renal or hepatic function. Following administration of a single 400 mg dose of [ 14 C]-sotagliflozin, the mean blood/plasma ratios for total radioactivity were 0.5 and 0.4 for C max and AUC 0-last , respectively, and the mean whole blood to plasma concentration ratio of sotagliflozin ranged from 0.5 to 0.6. The mean apparent volume of distribution of sotagliflozin following administration of a single 400 mg oral dose of [ 14 C]-sotagliflozin was 9000 L. Elimination Metabolism Following the administration of a single dose of 400 mg [ 14 C]-sotagliflozin in healthy subjects, sotagliflozin was extensively metabolized predominantly to sotagliflozin 3-O-glucuronide and it represented 94.3% of the radioactivity in plasma. The key enzymes responsible for the metabolism of sotagliflozin were UGT1A9 and, to a lesser extent, CYP3A4. Following incubation of sotagliflozin with UGT1A9, the 3-O-glucuronide metabolite of sotagliflozin was the main conjugate observed. No acyl glucuronides of sotagliflozin were identified. Excretion Following the administration of a single dose of 400 mg [ 14 C]-sotagliflozin, 57% and 37% of the radioactivity was recovered in the urine and feces, respectively. These results indicate that the main route of elimination was renal. The predominant metabolite detected in urine was sotagliflozin 3-O-glucuronide, representing a mean of 33% of the administered radioactive dose. Unchanged [ 14 C]-sotagliflozin was the predominant radioactive peak detected in fecal extracts representing a mean of 23% of the total administered radioactive dose. Sotagliflozin undergoes enterohepatic circulation. Following administration of 200 mg and 400 mg, mean terminal half-life (T 1/2 ) ranged from 21 to 35 hours for sotagliflozin and from 19 to 26 hours for sotagliflozin 3-O-glucuronide. Effective half-life of sotagliflozin ranged from 5 to 10 hours. Steady state was generally achieved after 5 days of once daily dosing with sotagliflozin 200 mg and 400 mg. In healthy volunteers, mean oral clearance (CL/F) of sotagliflozin ranged from 260 to 370 L/hr following administration of 200 mg and 400 mg sotagliflozin. The median population PK model predicted CL/F in type 2 diabetes mellitus patients with normal renal function was about 300 L/hr. Specific Populations Renal Impairment Exposure of sotagliflozin was evaluated in a dedicated PK study in subjects with mild (eGFR 60 to < 90 mL/min/1.73 m²) and moderate (eGFR 30 to < 60 mL/min/1.73 m²) renal impairment and with normal renal function (eGFR ≥ 90 mL/min/1.73 m²). Exposure to sotagliflozin following a single dose of 400 mg was approximately 70% higher in subjects with mild and up to 170% higher in subjects with moderate renal impairment compared to subjects with normal renal function [see Use in Specific Populations ( 8.6 )]. Hepatic Impairment In a study with subjects with reduced hepatic function, AUC of sotagliflozin was not increased in mild (Child Pugh A) hepatic impaired subjects but was increased by approximately 3-fold in moderate (Child Pugh B) and approximately 6-fold in severe (Child Pugh C) hepatic impaired subjects compared to subjects with normal hepatic function [see Use in Specific Populations ( 8.7 )] . Effects of Age, Sex, Race, and Body Weight on Pharmacokinetics Based on population PK analysis, age, body weight, sex and race (non-white versus primarily whites) do not have a clinically meaningful effect on the PK of sotagliflozin. Drug Interactions In Vitro Studies The major human metabolite of sotagliflozin, sotagliflozin 3-O-glucuronide, was shown to have an in vitro potential to inhibit CYP3A4 and CYP2D6 and to induce CYP3A4. Sotagliflozin was shown to have inhibitory effects on P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP). Sotagliflozin is a substrate of the human uptake transporters organic anion transporter (OAT)3, organic-anion-transporting polypeptides (OATP)1B1, and OATP1B3, but not OAT1 and organic cation transporter 2 (OCT2). Sotagliflozin does not inhibit any of these human uptake transporters at clinically relevant plasma concentrations. In Vivo Studies Figure 1 summarizes the effect on sotagliflozin by concomitantly administered drugs. The observed changes in overall exposure (AUC) of sotagliflozin following coadministration with hydrochlorothiazide, ramipril, metformin, mefenamic acid, and oral contraceptives are not considered to be clinically relevant. Rifampicin (UGT inducer) decreases exposure to sotagliflozin [see Drug Interactions ( 7.2 )].

The increases in exposure (AUC) of metoprolol (CYP2D6 substrate) and rosuvastatin (BCRP substrate), as well as the decrease in exposure to midazolam (CYP3A4 substrate) are not considered to be clinically relevant. The increased exposure (C max and AUC) in ramipril is not considered clinically significant because the exposure of ramiprilat, the primary active metabolite, is minimally increased. The increase in exposure (C max and AUC) of digoxin, a P-gp substrate, when coadministered with sotagliflozin, requires monitoring of patients [see Drug Interactions ( 7.1 )] .

No increase in QT corrected for heart rate (QTc) was observed with either 800 mg or 2000 mg sotagliflozin.

12.3 Pharmacokinetics Plasma C max and AUC of sotagliflozin increased in a dose-proportional manner in the therapeutic dose range of 200 mg to 400 mg once daily.

Specific Populations Renal Impairment Exposure of sotagliflozin was evaluated in a dedicated PK study in subjects with mild (eGFR 60 to < 90 mL/min/1.73 m²) and moderate (eGFR 30 to < 60 mL/min/1.73 m²) renal impairment and with normal renal function (eGFR ≥ 90 mL/min/1.73 m²). Exposure to sotagliflozin following a single dose of 400 mg was approximately 70% higher in subjects with mild and up to 170% higher in subjects with moderate renal impairment compared to subjects with normal renal function [see Use in Specific Populations ( 8.6 )].

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide ). Risk of Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, inform them that using INPEFA can increase their risk of life-threatening diabetic ketoacidosis. For all other patients, inform them that INPEFA can cause potentially fatal ketoacidosis and that type 2 diabetes mellitus is a risk factor. Educate all patients on precipitating factors (such as infection, reduced caloric intake, ketogenic diet, surgery, insulin dose reduction, dehydration, and alcohol abuse) and symptoms of ketoacidosis (including nausea, vomiting, abdominal pain, tiredness, and labored breathing). Inform patients that blood glucose may be normal even in the presence of ketoacidosis. Advise patients that they may be asked to monitor ketones. If symptoms of ketoacidosis occur, instruct patients to discontinue INPEFA and seek medical attention immediately [see Warnings and Precautions ( 5.1 )] . Volume Depletion Inform patients that symptomatic hypotension may occur with INPEFA and advise them to contact their healthcare provider if they experience such symptoms [see Warnings and Precautions ( 5.2 )] . Inform patients that dehydration may increase the risk for hypotension, and to have adequate fluid intake. Serious Urinary Tract Infections Inform patients of the potential for urinary tract infections, which may be serious. Provide them with information on the symptoms of urinary tract infections. Advise them to seek medical advice promptly if such symptoms occur [see Warnings and Precautions ( 5.3 )] . Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues Inform patients that the incidence of hypoglycemia is increased when INPEFA is used in combination with insulin and that a lower dose of insulin may be required to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.4 )] . Necrotizing Fasciitis of the Perineum (Fournier's Gangrene) Inform patients that necrotizing infections of the perineum (Fournier's Gangrene) have occurred with INPEFA in patients with diabetes mellitus. Counsel patients to promptly seek medical attention if they develop pain, tenderness, redness, or swelling of the genitals or the area from the genitals back to the rectum, along with a fever above 100.4°F or malaise [see Warnings and Precautions ( 5.5 )] . Genital Mycotic Infections in Females (e.g., Vulvovaginitis) Inform female patients that vaginal yeast infections may occur and provide them with information on the signs and symptoms of vaginal yeast infections. Advise them of treatment options and when to seek medical advice [see Warnings and Precautions ( 5.6 )] . Genital Mycotic Infections in Males (e.g., Balanitis) Inform male patients that yeast infections of the penis (e.g., balanitis or balanoposthitis) may occur, especially in patients with prior history. Provide them with information on the signs and symptoms of balanitis and balanoposthitis (rash or redness of the glans or foreskin of the penis). Advise them of treatment options and when to seek medical advice [see Warnings and Precautions ( 5.6 )] . Hypersensitivity Reactions Inform patients that hypersensitivity reactions (e.g., urticaria, anaphylactic reactions, and angioedema) have been reported with other SGLT2 inhibitors.

This Medication Guide has been approved by the U.S. Food and Drug Administration. Issued: 07/2023 MEDICATION GUIDE INPEFA TM ( in peh' fah ) (sotagliflozin) tablets, for oral use What is the most important information I should know about INPEFA? INPEFA can cause serious side effects, including: Ketoacidosis (acidic blood with increased ketones in your blood or urine). Ketoacidosis has happened in people who have type 1 or type 2 diabetes during treatment with INPEFA. Ketoacidosis can happen with INPEFA even if your blood sugar is not high. Your healthcare provider may ask you to periodically check ketones in your urine or blood. Ketoacidosis can also happen in people who are sick or who have surgery during treatment with INPEFA. Ketoacidosis is a serious condition which needs to be treated in a hospital. Ketoacidosis may lead to death. Stop taking INPEFA and call your healthcare provider or get medical help right away if you get any of the following symptoms. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL: nausea vomiting trouble breathing stomach-area (abdominal) pain tiredness ketones in your urine or blood Dehydration. INPEFA can cause some people to become dehydrated (the loss of body water and salt). Dehydration may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). There have been reports of sudden kidney injury due to dehydration in people with type 2 diabetes who are taking a medicine that works like INPEFA. You may be at higher risk of dehydration if you: take medicines to lower your blood pressure, including water pills (diuretics) are 65 years of age or older are on a low salt diet have kidney problems Talk to your healthcare provider about what you can do to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, for example if you cannot eat or you start to lose liquids from your body, for example from vomiting, diarrhea, or being in the sun too long. See “ What are the possible side effects of INPEFA? ” for more information about side effects. What is INPEFA? INPEFA is a prescription medicine used to reduce the risk of death due to heart problems (cardiovascular death), hospitalization for heart failure, and urgent visits to the doctor for heart failure in adults with: heart failure (when the heart is weak and cannot pump enough blood to the rest of your body), or type 2 diabetes, chronic kidney disease, and other cardiovascular risk factors. It is not known if INPEFA is safe and effective in children under 18 years of age. Do not take INPEFA if you: are allergic to sotagliflozin or any of the ingredients in INPEFA. See the end of this Medication Guide for a list of ingredients in INPEFA. Symptoms of a serious allergic reaction to INPEFA may include: skin rash raised red patches on your skin (hives) swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing If you have any of these symptoms, stop taking INPEFA and call your healthcare provider or go to the nearest hospital emergency room right away . Before taking INPEFA, tell your healthcare provider about all of your medical conditions, including if you: have type 1 diabetes or have had diabetic ketoacidosis. are going to have surgery or a procedure that requires fasting. Your healthcare provider may stop your INPEFA for at least 3 days before you have surgery. Talk to your healthcare provider if you are having surgery about when to stop taking INPEFA and when to start it again. are eating less or there is a change in your diet. have or have had problems with your pancreas, including pancreatitis or surgery on your pancreas. drink alcohol very often or drink a lot of alcohol over a short period (“binge” drinking). have a history of urinary tract infections or problems urinating. have a history of infection of the vagina or penis. have kidney or liver problems. are pregnant or plan to become pregnant. INPEFA may harm your unborn baby. Tell your healthcare provider right away if you become pregnant during treatment with INPEFA. Your healthcare provider may switch you to a different medicine. are breastfeeding or plan to breastfeed. It is not known if INPEFA passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with INPEFA. You should not breastfeed during treatment with INPEFA. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. INPEFA may affect the way other medicines work, and other medicines may affect how INPEFA works. How should I take INPEFA? Take INPEFA exactly as your healthcare provider tells you to take it. Do not change your dose of INPEFA without talking to your healthcare provider. Take INPEFA by mouth 1 time each day no more than 1 hour before your first meal of the day. Swallow INPEFA tablets whole. Do not cut, crush, or chew. If you miss a dose of INPEFA by more than 6 hours after taking INPEFA, take your next dose at your next scheduled time the next day. INPEFA will cause your urine to test positive for glucose. Your healthcare provider may do certain blood tests before you start INPEFA and during your treatment as needed. If you take too much INPEFA, call your healthcare provider or local poison control center, or go to the nearest emergency room right away. What are the possible side effects of INPEFA? INPEFA can cause serious side effects, including: See “ What is the most important information I should know about INPEFA? ” Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking INPEFA. Tell your healthcare provider if you have any signs or symptoms of a urinary tract infection such as a burning feeling when passing urine, a need to urinate often, the need to urinate right away, pain in the lower part of your stomach (pelvis), or blood in the urine. Sometimes people also may have a fever, back pain, nausea, or vomiting. Low blood sugar (hypoglycemia). If you take INPEFA with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you take INPEFA. Signs and symptoms of low blood sugar may include: headache shaking or feeling jittery irritability fast heartbeat weakness drowsiness sweating confusion dizziness hunger A rare but serious bacterial infection that causes damage to the tissue under the skin (necrotizing fasciitis) in the area between and around the anus and genitals (perineum). Necrotizing fasciitis of the perineum has happened in women and men with diabetes who take INPEFA. Necrotizing fasciitis of the perineum may lead to hospitalization, may require multiple surgeries, and may lead to death. Seek medical attention immediately if you have a fever or you are feeling very weak, tired, or uncomfortable (malaise) and you develop any of the following symptoms in the area between and around the anus and genitals: pain or tenderness swelling redness of skin (erythema) Vaginal yeast infection. Symptoms of a vaginal yeast infection include: vaginal odor white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese) vaginal itching Yeast infection of the penis (balanitis or balanoposthitis). Swelling of an uncircumcised penis may develop that makes it difficult to pull back the skin around the tip of the penis. Other symptoms of yeast infection of the penis include: redness, itching, or swelling of the penis rash of the penis foul smelling discharge from the penis pain in the skin around the penis Talk to your healthcare provider about what to do if you get symptoms of a yeast infection of the vagina or penis. Your healthcare provider may suggest you use an over-the-counter antifungal medicine. Talk to your healthcare provider right away if you use an over-the-counter antifungal medication and your symptoms do not go away. The most common side effects of INPEFA include: urinary tract infection dehydration diarrhea low blood sugar levels These are not all the possible side effects of INPEFA. For more information, ask your healthcare provider or pharmacist. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. How should I store INPEFA? Store INPEFA at room temperature between 68°F to 77°F (20°C to 25°C). Keep INPEFA and all medicines out of the reach of children.

14 CLINICAL STUDIES 14.1 SOLOIST Study The SOLOIST (Effects of Sotagliflozin on Clinical Outcomes in Hemodynamically Stable Patients with Type 2 Diabetes Post Worsening Heart Failure) study (NCT03521934) was a randomized, double-blind, placebo-controlled, parallel-group, multicenter study in patients with type 2 diabetes mellitus who had been admitted to the hospital, a heart failure unit, infusion center, or emergency department for worsening heart failure to determine if INPEFA reduces the risk of total occurrence of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit. Patients were randomized to treatment if they met the following criteria for clinical stability: no need for oxygen therapy, a systolic blood pressure of at least 100 mmHg, no need for intravenous inotropic or vasodilator therapy (excluding nitrates) and transitioned from intravenous to oral diuretic therapy. Of the 1,222 randomized patients, 608 were randomized to INPEFA and 614 to placebo. Assigned treatment was initiated in the hospital or within a median of 2 days following hospital discharge. The dose of study drug was to be up-titrated from 200 mg to 400 mg sotagliflozin or matching placebo as soon as 2 weeks or up until 8 months after initiation of treatment. The dose was increased to 400 mg once daily for 336 patients (56%) in the sotagliflozin group and 325 patients (53%) in the placebo group. The median time to up-titration was 16 days. Up-titration was to be performed based on the judgment of the investigator, who considered whether the patient's clinical condition was satisfactory, whether the drug was well tolerated, and whether AEs typical of SGLT2 inhibitors had occurred, such as those associated with volume depletion. At baseline, median age was 70 years, 34% were female, 93% were White and 4% were Black or African American. Median A1C was 7.1%, median body mass index (BMI) was 31 kg/m 2 , and median eGFR was 50 mL/min/1.73 m 2 . Median left ventricular ejection fraction (LVEF) was 35% (79% with LVEF < 50%), median N-terminal pro B-type natriuretic peptide (NT-proBNP) was 1806 pg/mL, and the median Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) score was 41. At baseline, 86% were treated with at least one antihyperglycemic medication, including 52% with a biguanide, 36% with insulin, 19% with a sulfonylurea, 16% with a dipeptidyl peptidase-4 (DPP4) inhibitor, and 3% with a glucagon-like peptide 1 (GLP-1) receptor agonist. At baseline, 91% were treated with inhibitors of the renin-angiotensin-aldosterone system, 92% with a beta blocker, 95% with a loop diuretic, and 10% with another diuretic. INPEFA was superior to placebo in reducing the risk of the primary composite endpoint (Hazard Ratio [HR] 0.67 [95% confidence interval (CI) 0.53, 0.85]; p = 0.001). ( Table 2 ).

Apparent homogeneity or heterogeneity among groups should not be over-interpreted. Figure 3 Figure 4 14.2 SCORED Study The SCORED (Effects of Sotagliflozin on Cardiovascular and Renal Events in Patients with Type 2 Diabetes Mellitus, Cardiovascular Risk Factors and Moderately Impaired Renal Function) study (NCT03315143) was a randomized, double-blind, placebo-controlled, parallel-group, multicenter study in patients with type 2 diabetes mellitus (A1C > 7%), chronic kidney disease (eGFR 25 to 60 mL/min/1.73 m 2 ), and additional cardiovascular risk factors, such as a history of heart failure, obesity, dyslipidemia, hypertension, or elevated cardiac and inflammatory biomarkers, to determine if INPEFA reduces the risk of total occurrence of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit. Of the 10,584 randomized patients, 5,292 were randomized to INPEFA and 5,292 to placebo. The dose of study drug was to be up-titrated from 200 mg to 400 mg sotagliflozin or matching placebo as soon as 4 weeks or up until 6 months after initiation of treatment. The dose was increased to 400 mg once daily for 3,934 patients (74%) in the INPEFA group and for 3,987 patients (75%) in the placebo group. The median time to up-titration was 29 days. Up-titration was to be performed based on the judgment of the investigator, who considered whether the patient's clinical condition was satisfactory, whether the drug was well tolerated, and whether AEs typical of SGLT2 inhibitors had occurred, such as those associated with volume depletion. At baseline, median age was 68 years, 45% were female, 82% were White, 3% Black or African American, 6% Asian, and 4% American Indian or Native Alaskan. Median A1C was 8.3%, median BMI was 32 kg/m 2 , median eGFR was 45 mL/min/1.73 m 2 (8% with eGFR < 30, 44% with eGFR 30 to < 45, and 48% with eGFR ≥ 45 mL/min/1.73 m 2 ), and median urinary albumin-to-creatinine ratio (UACR) was 82 mg/g (32% with UACR ≥ 300 mg/g). A history of heart failure was present in 31%, prior myocardial infarction had occurred in 20%, a prior cerebrovascular event had occurred in 9%, and coronary revascularization had been performed in 22% of patients prior to study entry. At baseline, 97% were treated with at least one antihyperglycemic medication, including 56% with a biguanide, 64% with insulin, 27% with a sulfonylurea, 20% with a DPP4 inhibitor, and 6% with a GLP-1 receptor agonist. At baseline, 88% were treated with inhibitors of the renin-angiotensin-aldosterone system, 14% with a beta blocker, 42% with a calcium channel blocker, 35% with a loop diuretic, and 30% with another diuretic. INPEFA was superior to placebo in reducing the risk of the primary composite endpoint (HR 0.75 [95% CI 0.63, 0.88]; p < 0.001) ( Table 3 ).

8.5 Geriatric Use No INPEFA dosage change is recommended based on age. In the SOLOIST study, a total of 241 (40%) patients treated with INPEFA were between 65 and < 75 years of age, and 174 (29%) were ≥ 75 years of age. In the SCORED study, a total of 2,470 (47%) patients treated with INPEFA were between 65 and < 75 years of age, and 1,240 (23%) were ≥ 75 years of age. No overall differences in efficacy were detected between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients may be at increased risk for volume depletion adverse reactions, including hypotension. In patients ≥ 65 years of age, a higher proportion of patients treated with INPEFA had adverse reactions of volume depletion [see Warnings and Precautions ( 5.2 ) and Adverse Reactions ( 6.1 )].

8.4 Pediatric Use The safety and effectiveness of INPEFA in pediatric patients under 18 years of age have not been established.

8.1 Pregnancy Risk Summary Based on animal data showing renal effects, INPEFA is not recommended during the second and third trimesters of pregnancy. Available data with INPEFA in pregnant women are insufficient to evaluate for 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 untreated heart failure in pregnancy [see Clinical Considerations ] . In rats, renal changes were observed when sotagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy. Exposure approximately 5 times the clinical exposure at the maximum recommended human dose (MRHD) of 400 mg once daily caused increased kidney weights and renal pelvis and tubule dilatations that were partially reversible [see Data ] . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. 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 Pregnant women with congestive heart failure are at increased risk for preterm birth. Clinical classification of heart disease may worsen with pregnancy and lead to maternal death. Data Animal Data In embryo-fetal development studies in rats and rabbits, sotagliflozin was administered for intervals coinciding with the first trimester period of organogenesis in humans. Sotagliflozin was not teratogenic when administered at doses up to 100 mg/kg/day in pregnant rats during embryonic organogenesis (40 times the human exposure at the MRHD). Higher exposures (350 mg/kg or 161 times the human exposure at the MRHD) resulted in embryo-lethality, effects on fetal growth, and cardiovascular and skeletal fetal abnormalities commensurate with maternal toxicity. Sotagliflozin was not teratogenic when administered at doses up to 200 mg/kg/day in pregnant rabbits (9 times the human exposure at the MRHD). In a prenatal and postnatal development study in pregnant and lactating rats, sotagliflozin was administered at oral doses up to 100 mg/kg/day from gestation Day 6 through to lactation Day 20 (weaning). An increased incidence of dilated kidneys with discoloration and dilated ureters was observed at doses ≥ 30 mg/kg (≥ 4 times the human exposure at the MRHD). Sotagliflozin did not adversely affect developmental landmarks, sexual maturation, or reproductive performance of the offspring at doses up to 40 times the human exposure at the MRHD. Sotagliflozin dosed directly to juvenile rats from postnatal Day (PND) 21 until PND 90 at doses of 3, 10, 30, and 75 mg/kg/day caused dose-related increased kidney weights for males given ≥ 10 mg/kg/day and females given ≥ 30 mg/kg/day and was correlated with renal tubular and pelvis dilation for animals given ≥ 30 mg/kg/day. These findings were fully or partially reversed after a 29-day recovery period. These outcomes occurred with drug exposure during periods of renal development in rats that correspond to the late second and third trimesters of human development.

8 USE IN SPECIFIC POPULATIONS Pregnancy : Advise females of the potential risk to a fetus especially during the second and third trimesters. ( 8.1 ) Lactation : INPEFA is not recommended when breastfeeding. ( 8.2 ) Geriatrics : Higher incidence of adverse reactions related to volume depletion. ( 5.2 , 8.5 ) Renal Impairment : Higher incidence of adverse reactions related to volume depletion.

These findings were fully or partially reversed after a 29-day recovery period. These outcomes occurred with drug exposure during periods of renal development in rats that correspond to the late second and third trimesters of human development. 8.2 Lactation Risk Summary There are no data on the presence of INPEFA in human milk, the effects on the breastfed infant, or the effects on milk production. Sotagliflozin is present in rat milk (see Data ). When a drug is present in animal milk, it is likely to be present in human milk. 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 breastfeeding is not recommended while taking INPEFA. Data In rats, after a single oral dose of radiolabeled sotagliflozin to dams on gestation Day 13 or 18, low to moderate levels of radioactivity were present in fetal tissues. In rat milk, the mean milk/plasma concentration ratios ranged from 0.5 to 2. Exposure to radioactivity was approximately 30% greater in milk than in plasma based on AUC 0-inf values. 8.4 Pediatric Use The safety and effectiveness of INPEFA in pediatric patients under 18 years of age have not been established. 8.5 Geriatric Use No INPEFA dosage change is recommended based on age. In the SOLOIST study, a total of 241 (40%) patients treated with INPEFA were between 65 and < 75 years of age, and 174 (29%) were ≥ 75 years of age. In the SCORED study, a total of 2,470 (47%) patients treated with INPEFA were between 65 and < 75 years of age, and 1,240 (23%) were ≥ 75 years of age. No overall differences in efficacy were detected between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients may be at increased risk for volume depletion adverse reactions, including hypotension. In patients ≥ 65 years of age, a higher proportion of patients treated with INPEFA had adverse reactions of volume depletion [see Warnings and Precautions ( 5.2 ) and Adverse Reactions ( 6.1 )]. 8.6 Renal Impairment INPEFA was evaluated in 5,292 patients with chronic kidney disease (eGFR 25 to 60 mL/min/1.73 m 2 ) in the SCORED study and in 426 patients with heart failure with eGFR < 60 mL/min/1.73 m 2 in the SOLOIST study. The safety profile of INPEFA across eGFR subgroups in these studies was consistent with the known safety profile. There was an increase in volume-related adverse events (e.g., hypotension, dizziness) in patients with eGFR < 30 mL/min/1.73 m 2 relative to the overall safety population [see Warnings and Precautions ( 5.2 ) and Adverse Reactions ( 6.1 )]. Efficacy and safety studies with INPEFA did not enroll patients with an eGFR less than 25 mL/min/1.73 m 2 or on dialysis. After starting therapy in these studies, patients were discontinued if eGFR fell below 15 mL/min/1.73 m 2 or were initiated on chronic dialysis. 8.7 Hepatic Impairment In a clinical pharmacology study in patients with hepatic impairment, the exposure in mild hepatic impairment was not increased, but was approximately 3-fold as high in moderate and approximately 6-fold as high in severely hepatic-impaired subjects compared to subjects with normal hepatic function [see Clinical Pharmacology ( 12.3 )] . No dosage adjustment is necessary in patients with mild hepatic impairment. The safety and efficacy of INPEFA have not been established in patients with moderate or severe hepatic impairment [see Clinical Pharmacology ( 12.3 )] . INPEFA is not recommended in patients with moderate or severe hepatic impairment.
