QTERN tablets for oral use contain dapagliflozin and saxagliptin. Dapagliflozin propanediol is an active inhibitor of sodium‑glucose cotransporter 2 (SGLT2). It is described chemically as D‑glucitol, 1,5‑anhydro‑1‑C‑[4‑chloro‑3‑[(4‑ethoxyphenyl)methyl]phenyl] ‑, (1 S )‑. Dapagliflozin is compounded with (2 S )‑1,2‑propanediol, hydrate (1:1:1) with an empirical formula as C 21 H 25 ClO 6 •C 3 H 8 O 2 •H 2 O and the molecular weight of 502.98. The structural formula is: Saxagliptin is an active inhibitor of the dipeptidyl‑peptidase‑4 (DPP‑4) enzyme. It is isolated in the monohydrate form chemically known as (1 S ,3 S ,5 S )‑2‑[(2 S )‑2‑amino‑2‑(3‑hydroxytricyclo [3.3.1.1] dec‑1‑yl)acetyl] ‑2‑azabicyclo[3.1.0]hexane‑3‑carbonitrile, monohydrate or (1 S ,3 S ,5 S )‑2‑[(2 S )‑2‑amino‑2‑(3‑hydroxy‑1‑adamantan‑1‑yl)acetyl]‑2‑azabicyclo[3.1.0] hexane‑3‑carbonitrile hydrate. The empirical formula is C 18 H 25 N 3 O 2 •H 2 O and the molecular weight is 333.43. The structural formula is: QTERN is available as film-coated tablets of two strengths: • 5 mg dapagliflozin/5 mg saxagliptin. Each tablet contains 5 mg dapagliflozin (equivalent to 6.15 mg dapagliflozin propanediol) and 5 mg saxagliptin (exists in the form of HCl salt). • 10 mg dapagliflozin/5 mg saxagliptin. Each tablet contains 10 mg dapagliflozin (equivalent to 12.3 mg dapagliflozin propanediol) and 5 mg saxagliptin (exists in the form of HCl salt). Each tablet also contains the following inactive ingredients: anhydrous lactose, croscarmellose sodium, iron oxides, magnesium stearate, microcrystalline cellulose, polyvinyl alcohol, polyethylene glycol, silicon dioxide, talc, and titanium dioxide. Hydrochloric acid and sodium hydroxide (if needed) are added for pH adjustment.

Table 3: Clinically Relevant Interactions with QTERN Strong Inhibitors of CYP3A4/5 Enzymes Clinical Impact Ketoconazole significantly increased saxagliptin exposure. Similar significant increases in plasma concentrations of saxagliptin are anticipated with other strong CYP3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin). Intervention Do not coadminister QTERN with strong cytochrome P450 3A4/5 inhibitors [see DOSAGE AND ADMINISTRATION (2.4 ) and CLINICAL PHARMACOLOGY (12.3) ] . Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when QTERN is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) [see WARNINGS AND PRECUATIONS (5.6) ] . Intervention Concomitant use may require lower doses of insulin or the insulin secretagogue to reduce the risk of hypoglycemia. Lithium Clinical Impact Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently during QTERN 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.

Safety and effectiveness of QTERN in pediatric patients under 18 years of age have not been established.

Because elderly patients are more likely to have decreased renal function, care should be taken when using QTERN in the elderly based on renal function [see DOSAGE AND ADMINISTRATION (2.3) ] . Dapagliflozin A total of 1424 (24%) of the 5936 dapagliflozin-treated patients were 65 years and older and 207 (3.5%) patients were 75 years and older in a pool of 21 double-blind, controlled, clinical studies assessing the efficacy of dapagliflozin in improving glycemic control. After controlling for level of renal function (eGFR), in clinical studies with dapagliflozin, efficacy was similar for patients under age 65 years and those 65 years and older. In patients 65 years and older, a higher proportion of patients treated with dapagliflozin had adverse reactions of hypotension [see WARNINGS AND PRECAUTIONS (5.4) ] . Saxagliptin In the seven double-blind, controlled clinical safety and efficacy trials of saxagliptin, a total of 4751 (42.0%) of the 11,301 patients randomized to saxagliptin were 65 years and over, and 1210 (10.7%) were 75 years and over. No overall differences in safety or effectiveness were observed between subjects ≥65 years old and younger subjects. While this clinical experience has not identified differences in responses between the elderly and younger patients, greater sensitivity of some older individuals cannot be ruled out.

QTERN No animal studies have been conducted with the combined products in QTERN to evaluate carcinogenesis, mutagenesis, or impairment of fertility. The following data are based on the findings in the studies with dapagliflozin and saxagliptin individually. Dapagliflozin Carcinogenesis Dapagliflozin did not induce tumors in either mice or rats at any of the doses evaluated in 2-year carcinogenicity studies. Oral doses in mice consisted of 5, 15, and 40 mg/kg/day in males and 2, 10, and 20 mg/kg/day in females, and oral doses in rats were 0.5, 2, and 10 mg/kg/day for both males and females. The highest doses evaluated in mice were approximately 72-times (males) and 105-times (females) the clinical dose of 10 mg per day, based on AUC exposure. In rats, the highest dose was approximately 131-times (males) and 186-times (females) the clinical dose of 10 mg per day, based on AUC exposure. Mutagenesis Dapagliflozin was negative in the Ames mutagenicity assay and was positive in a series of in vitro clastogenicity assays in the presence of S9 activation and at concentrations greater than or equal to 100 µg/mL. Dapagliflozin was negative for clastogenicity in a series of in vivo studies evaluating micronuclei or DNA repair in rats at exposure multiples greater than 2100-times the clinical dose. Impairment of Fertility Dapagliflozin had no effects on mating, fertility, or early embryonic development in treated male or female rats at exposure multiples less than or equal to 1708-times and 998-times the maximum recommended human dose in males and females, respectively. Saxagliptin Carcinogenesis Carcinogenicity was evaluated in 2-year studies conducted in CD-1 mice and Sprague-Dawley rats. Saxagliptin did not increase the incidence of tumors in mice dosed orally at 50, 250, and 600 mg/kg up to 870-times (males) and 1165-times (females) the 5 mg/day clinical dose, based on AUC. Saxagliptin did not increase the incidence of tumors in rats dosed orally at 25, 75, 150, and 300 mg/kg up to 355-times (males) and 2217-times (females) the 5 mg/day clinical dose, based on AUC. Mutagenesis Saxagliptin was not mutagenic or clastogenic in a battery of genotoxicity tests (Ames bacterial mutagenesis, human and rat lymphocyte cytogenetics, rat bone marrow micronucleus and DNA repair assays). The active metabolite of saxagliptin was not mutagenic in an Ames bacterial assay. Impairment of Fertility Saxagliptin administered to rats had no effect on fertility or the ability to maintain a litter at exposures up to 603-times and 776-times the 5 mg clinical dose in males and females, based on AUC.

The following important adverse reactions are described below or elsewhere in the labeling: • Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis [see WARNINGS AND PRECAUTIONS (5.1) ] • Pancreatitis [see WARNINGS AND PRECAUTIONS (5.2) ] • Heart Failure [see WARNINGS AND PRECAUTIONS (5.3) ] • Volume Depletion [see WARNINGS AND PRECAUTIONS (5.4) ] • Urosepsis and Pyelonephritis [see WARNINGS AND PRECAUTIONS (5.5) ] • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues [see WARNINGS AND PRECAUTIONS (5.6) ] • Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene) [see WARNINGS AND PRECAUTIONS (5.7) ] • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS (5.8) ] • Genital Mycotic Infections [see WARNINGS AND PRECAUTIONS (5.9) ] • Severe and Disabling Arthralgia [see WARNINGS AND PRECAUTIONS (5.10) ] • Bullous Pemphigoid [see WARNINGS AND PRECAUTIONS (5.11) ]

In the event of an overdose, contact the Poison Control Center. Appropriate supportive treatment should be initiated as dictated by the patient’s clinical status. The removal of dapagliflozin by hemodialysis has not been studied. Saxagliptin and its major metabolite can be removed by hemodialysis (23% of dose over 4 hours).

Saxagliptin Saxagliptin produced adverse skin changes in the extremities of cynomolgus monkeys (scabs and/or ulceration of tail, digits, scrotum, and/or nose). Skin lesions were reversible within exposure approximately 20-times the 5 mg clinical dose, but in some cases were irreversible and necrotizing at higher exposures. Adverse skin changes were not observed at exposures similar to (1- to 3-times) the 5 mg clinical dose. Clinical correlates to skin lesions in monkeys have not been observed in human clinical trials of saxagliptin.

The dapagliflozin and saxagliptin in combination with metformin has been studied in adult patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin in the following studies. Treatment with dapagliflozin and saxagliptin and metformin (combination or add-on therapy) at all doses produced statistically significant improvements in HbA1c compared to the active comparator or placebo study arms in combination with metformin.

Risk Summary Based on animal data showing adverse renal effects from dapagliflozin, QTERN is not recommended during the second and third trimesters of pregnancy. The limited available data with QTERN or its components (dapagliflozin and saxagliptin) in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. 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 tubular dilatations, that were not fully reversible, were observed in rats when dapagliflozin (a component of QTERN) was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy, at all doses tested; the lowest of which provided an exposure 15-times the 10 mg clinical dose ( see Data ) . No adverse developmental effects were observed when saxagliptin was administered to pregnant rats and rabbits (see Data ) . The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with an HbA1c greater than 7% and has been reported to be as high as 20 to 25% in women with an HbA1c greater than 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 embryofetal risk 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 Dapagliflozin Dapagliflozin dosed directly to juvenile rats from postnatal day (PND) 21 until PND 90 at doses of 1, 15, or 75 mg/kg/day, increased kidney weights and increased the incidence of renal pelvic and tubular dilatations at all dose levels. Exposure at the lowest dose was 15-times the 10 mg clinical dose (based on AUC). The renal pelvic and tubular dilatations observed in juvenile animals did not fully reverse within a 1-month recovery period. In a prenatal and postnatal development study, dapagliflozin was administered to maternal rats from gestation Day 6 through lactation Day 21 at doses of 1, 15, or 75 mg/kg/day, and pups were indirectly exposed in utero and throughout lactation. Increased incidence or severity of renal pelvic dilatation was observed in 21 day-old pup offspring of treated dams at 75 mg/kg/day (maternal and pup dapagliflozin exposures were 1415-times and 137-times, respectively, the human values at the 10 mg clinical dose, based on AUC). Dose-related reductions in pup body weights were observed at greater than or equal to 29-times the 10 mg clinical dose (based on AUC). No adverse effects on developmental endpoints were noted at 1 mg/kg/day, (19-times the 10 mg clinical dose, based on AUC). These outcomes occurred with drug exposure during periods of renal development in rats that corresponds to the late second and third trimester of human development. In embryofetal development studies in rats and rabbits, dapagliflozin was administered throughout organogenesis, corresponding to the first trimester of human pregnancy. In rats, dapagliflozin was neither embryolethal nor teratogenic at doses up to 75 mg/kg/day (1441-times the 10 mg clinical dose, based on AUC). Dose-related effects on the rat fetus (structural abnormalities and reduced body weight) occurred only at higher dosages, equal to or greater than 150 mg/kg (more than 2344-times the 10 mg clinical dose, based on AUC), which were associated with maternal toxicity. No developmental toxicities were observed in rabbits at doses up to 180 mg/kg/day (1191-times the 10 mg clinical dose, based on AUC). Saxagliptin In embryofetal development studies, saxagliptin was administered to pregnant rats and rabbits during the period of organogenesis, corresponding to the first trimester of human pregnancy. No adverse developmental effects were observed in either species at exposures 1503- and 152-times the 5 mg clinical dose in rats and rabbits, respectively, based on AUC. Saxagliptin crosses the placenta into the fetus following dosing in pregnant rats. In a prenatal and postnatal development study, no adverse developmental effects were observed in maternal rats administered saxagliptin from gestation day 6 through lactation day 21 at exposures up to 470-times the 5 mg clinical dose, based on AUC.

Assess renal function prior to initiation of QTERN therapy and periodically thereafter [see WARNINGS AND PRECAUTIONS (5.4) ] . Assess volume status. In patients with volume depletion, correct this condition before initiating QTERN [see WARNINGS AND PRECAUTIONS (5.4) and USE IN SPECIFIC POPULATIONS (8.5,   8.6) ] .

MEDICATION GUIDE QTERN ® [CUE-turn] (dapagliflozin and saxagliptin) tablets, for oral use What is the most important information I should know about QTERN? Serious side effects can happen to people taking QTERN, including: • • Diabetic Ketoacidosis (increased ketones in your blood or urine) in people with type 1 diabetes and other ketoacidosis. QTERN can cause ketoacidosis that can be life-threatening and may lead to death. Ketoacidosis is a serious condition which needs to be treated in a hospital. People with type 1 diabetes have a high risk of getting ketoacidosis. People with type 2 diabetes or pancreas problems also have an increased risk of getting ketoacidosis. Ketoacidosis can also happen in people who are sick, cannot eat or drink as usual, skip meals, are on a diet high in fat and low in carbohydrates (ketogenic diet), take less than the usual amount of insulin or miss insulin doses, drink too much alcohol, have a loss of too much fluid from the body (volume depletion), or who have surgery. Ketoacidosis can happen even if your blood sugar is less than 250 mg/dL. Your healthcare provider may ask you to periodically check ketones in your urine or blood.   Stop taking QTERN and call your healthcare provider or get medical help right away if you get any of the following. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL. ∘ nausea ∘ vomiting ∘ stomach area (abdominal) pain ∘ tiredness ∘ trouble breathing ∘ ketones in your urine or blood • Inflammation of the pancreas (pancreatitis). Saxagliptin, one of the medicines in QTERN, can cause inflammation of the pancreas, which may be severe and lead to death. Certain medical problems make you more likely to get pancreatitis. Before you start taking QTERN, tell your healthcare provider if you have ever had: ∘ inflammation of your pancreas (pancreatitis) ∘ stones in your gallbladder (gallstones) ∘ a history of alcoholism ∘ high blood triglyceride levels   It is not known if having these medical problems will make you more likely to get pancreatitis with QTERN. Stop taking QTERN and contact your healthcare provider right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis. • Heart failure. Heart failure means your heart does not pump blood well enough. Before you start taking QTERN, tell your healthcare provider if you have ever had heart failure or have problems with your kidneys. Contact your healthcare provider right away if you have any of the following symptoms: ∘ increasing shortness of breath or trouble breathing, especially when you lie down ∘ swelling or fluid retention, especially in the feet, ankles, or legs ∘ an unusually fast increase in weight ∘ unusual tiredness   These may be symptoms of heart failure. • Dehydration. QTERN 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 in people with Type 2 diabetes who are taking dapagliflozin, a component of QTERN. You may be at a higher risk of dehydration if you: ∘ take medicines to lower your blood pressure, including water pills (diuretics) ∘ are on a low salt diet ∘ have kidney problems ∘ are 65 years of age or older   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. What is QTERN? QTERN is a prescription medicine that contains dapagliflozin and saxagliptin. QTERN is used along with diet and exercise to improve blood sugar (glucose) control in adults with type 2 diabetes. • QTERN is not for use to improve blood sugar (glucose) control in people with type 1 diabetes. • It is not known if QTERN is safe and effective in children younger than 18 years of age.

Breastfeeding is not recommended while taking QTERN. Tell your healthcare provider about all the medicines you take , including prescription and over-the-counter medicines, vitamins, and herbal supplements. QTERN may affect the way other medicines work, and other medicines may affect how QTERN works. Contact your healthcare provider if you will be starting or stopping certain other types of medicines such as antibiotics or medicines that treat fungus or HIV/AIDS, because your dose of QTERN might need to be changed. Know the medicines you take. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine. How should I take QTERN? • Take QTERN exactly as your healthcare provider tells you to take it. • Take QTERN by mouth 1 time each day in the morning with or without food. • Your healthcare provider will tell you how much QTERN to take and when to take it. Your healthcare provider may change your dose if needed. • Swallow QTERN whole. Do not crush, cut or chew QTERN tablets. • If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take 2 doses of QTERN at the same time unless your healthcare provider tells you to do so. Talk to your healthcare provider if you have questions about a missed dose. • If you take too much QTERN, call your healthcare provider, or go to the nearest hospital emergency room right away. • During periods of stress on the body, such as fever, trauma, infection, or surgery, the amount of diabetes medicine you need may change. Tell your healthcare provider right away if you have any of these conditions and follow your healthcare provider’s instructions. • Your healthcare provider may tell you to take QTERN along with other diabetes medicines. Low blood sugar can happen more often when QTERN is taken with certain other diabetes medicines. See “ What are the possible side effects of QTERN? ”. • QTERN will cause your urine to test positive for glucose. • Your healthcare provider may do certain blood tests before you start QTERN and during treatment as needed. Your healthcare provider may change your dose of QTERN based on the results of your blood tests. What are the possible side effects of QTERN? QTERN may cause serious side effects, including: • See “What is the most important information I should know about QTERN?”. • Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking dapagliflozin. 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 QTERN with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, this can increase your risk of getting low blood sugar.

Dapagliflozin Sodium-glucose cotransporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Dapagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, dapagliflozin reduces reabsorption of filtered glucose and thereby promotes urinary glucose excretion. Saxagliptin Increased concentrations of the incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the bloodstream from the small intestine in response to meals. These hormones cause insulin release from the pancreatic beta cells in a glucose-dependent manner but are inactivated by the DPP-4 enzyme within minutes. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, reducing hepatic glucose production. In patients with type 2 diabetes mellitus, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Saxagliptin is a competitive DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 diabetes mellitus.

Dapagliflozin Increases in the amount of glucose excreted in the urine were observed in healthy subjects and in patients with type 2 diabetes mellitus following the administration of dapagliflozin. Dapagliflozin dose of 5 or 10 mg per day in patients with type 2 diabetes mellitus for 12 weeks resulted in excretion of approximately 70 grams of glucose in the urine per day at Week 12. A near maximum glucose excretion was observed at the dapagliflozin daily dose of 20 mg. This urinary glucose excretion with dapagliflozin also results in increases in urinary volume [see ADVERSE REACTIONS (6.1) ] . After discontinuation of dapagliflozin, on average, the elevation in urinary glucose excretion approaches baseline by about 3 days from discontinuation for the 10 mg dose. Figure 1: Scatter Plot and Fitted Line of Change from Baseline in 24-Hour Urinary Glucose Amount versus Dapagliflozin Dose in Healthy Subjects and Subjects with Type 2 Diabetes Mellitus (T2DM) (Semi-Log Plot) Saxagliptin In patients with type 2 diabetes mellitus, administration of saxagliptin inhibits DPP-4 enzyme activity for a 24-hour period. After an oral glucose load or a meal, this DPP-4 inhibition resulted in a 2- to 3-fold increase in circulating levels of active GLP-1 and GIP, decreased glucagon concentrations, and increased glucose-dependent insulin secretion from pancreatic beta cells. The rise in insulin and decrease in glucagon were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal. Cardiac Electrophysiology Dapagliflozin Dapagliflozin was not associated with clinically meaningful prolongation of QTc interval at daily doses up to 150 mg (15-times the recommended maximum dose) in a study of healthy subjects. In addition, no clinically meaningful effect on QTc interval was observed following single doses of up to 500 mg (50-times the recommended maximum daily dose) of dapagliflozin in healthy subjects. Saxagliptin In a randomized, double-blind, placebo-controlled, 4-way crossover, active comparator study using moxifloxacin in 40 healthy subjects, saxagliptin was not associated with clinically meaningful prolongation of the QTc interval or heart rate at daily doses up to 40 mg (8-times the recommended maximum daily dose).

Overall, the pharmacokinetics of dapagliflozin and saxagliptin were not affected in a clinically relevant manner when administered as QTERN. Saxagliptin The pharmacokinetics of saxagliptin and its active metabolite, 5-hydroxy saxagliptin, were similar in healthy subjects and in patients with type 2 diabetes mellitus. The C max and AUC values of saxagliptin and its active metabolite increased proportionally in the 2.5 to 400 mg dose range. Following a 5 mg single oral dose of saxagliptin to healthy subjects, the mean plasma AUC values for saxagliptin and its active metabolite were 78 ng•h/mL and 214 ng•h/mL, respectively. The corresponding plasma C max values were 24 ng/mL and 47 ng/mL, respectively. The average variability (%CV) for AUC and C max for both saxagliptin and its active metabolite was less than 25%. No appreciable accumulation of either saxagliptin or its active metabolite was observed with repeated once daily dosing at any dose level. No dose- and time-dependence were observed in the clearance of saxagliptin and its active metabolite over 14 days of once daily dosing with saxagliptin at doses ranging from 2.5 to 400 mg. Absorption Dapagliflozin Following oral administration of dapagliflozin, the maximum plasma concentration (C max ) is usually attained within 2 hours under fasting state. The C max and AUC values increase dose proportionally with increase in dapagliflozin dose in the therapeutic dose range. The absolute oral bioavailability of dapagliflozin following the administration of a 10 mg dose is 78%. Administration of dapagliflozin with a high-fat meal decreases its C max by up to 50% and prolongs T max by approximately 1 hour but does not alter AUC as compared with the fasted state. Saxagliptin The median time to maximum concentration (T max ) following the 5 mg once daily dose was 2 hours for saxagliptin and 4 hours for its active metabolite. Administration with a high-fat meal resulted in an increase in T max of saxagliptin by approximately 20 minutes as compared to fasted conditions. There was a 27% increase in the AUC of saxagliptin when given with a meal as compared to fasted conditions. Distribution Dapagliflozin Dapagliflozin is approximately 91% protein bound. Protein binding is not altered in patients with renal or hepatic impairment. Saxagliptin The in vitro protein binding of saxagliptin and its active metabolite in human serum is negligible. Therefore, changes in blood protein levels in various disease states (e.g., renal or hepatic impairment) are not expected to alter the disposition of saxagliptin. Metabolism Dapagliflozin The metabolism of dapagliflozin is primarily mediated by UGT1A9; CYP-mediated metabolism is a minor clearance pathway in humans. Dapagliflozin is extensively metabolized, primarily to yield dapagliflozin 3-O-glucuronide, which is an inactive metabolite. Dapagliflozin 3-O-glucuronide accounted for 61% of a 50 mg [ 14 C]-dapagliflozin dose and is the predominant drug-related component in human plasma. Saxagliptin The metabolism of saxagliptin is primarily mediated by cytochrome P450 3A4/5 (CYP3A4/5). The major metabolite of saxagliptin is also a DPP-4 inhibitor, which is one-half as potent as saxagliptin. Therefore, strong CYP3A4/5 inhibitors and inducers will alter the pharmacokinetics of saxagliptin and its active metabolite [see DRUG INTERACTIONS (7) ] . Elimination Dapagliflozin Dapagliflozin and related metabolites are primarily eliminated via the renal pathway. Following a single 50 mg dose of [ 14 C]-dapagliflozin, 75% and 21% total radioactivity is excreted in urine and feces, respectively. In urine, less than 2% of the dose is excreted as parent drug. In feces, approximately 15% of the dose is excreted as parent drug. The mean plasma terminal half-life (t 1/2 ) for dapagliflozin is approximately 12.9 hours following a single oral dose of dapagliflozin 10 mg. Saxagliptin Saxagliptin is eliminated by both renal and hepatic pathways. Following a single 50 mg dose of [ 14 C]-saxagliptin, 24%, 36%, and 75% of the dose was excreted in the urine as saxagliptin, its active metabolite, and total radioactivity, respectively. The average renal clearance of saxagliptin (~230 mL/min) was greater than the average estimated glomerular filtration rate (~120 mL/min), suggesting some active renal excretion. A total of 22% of the administered radioactivity was recovered in feces representing the fraction of the saxagliptin dose excreted in bile and/or unabsorbed drug from the gastrointestinal tract. Following a single oral dose of saxagliptin 5 mg to healthy subjects, the mean plasma terminal half-life (t 1/2 ) for saxagliptin and its active metabolite was 2.5 and 3.1 hours, respectively. Specific Populations Effects of Age, Gender, Race and Body Weight on Pharmacokinetics Based on a population pharmacokinetic analysis, age, gender, race, and body weight do not have a clinically meaningful effect on the pharmacokinetics of saxagliptin and dapagliflozin. Renal Impairment Dapagliflozin At steady state (20 mg once daily dapagliflozin for 7 days), patients with type 2 diabetes mellitus with mild, moderate, or severe renal impairment (as determined by eGFR) had geometric mean systemic exposures of dapagliflozin that were 45%, 100%, and 200% higher, respectively, as compared to patients with type 2 diabetes mellitus with normal renal function. Higher systemic exposure of dapagliflozin in patients with type 2 diabetes mellitus with renal impairment did not result in a correspondingly higher 24-hour urinary glucose excretion. The steady-state 24-hour urinary glucose excretion in patients with type 2 diabetes mellitus and mild, moderate, and severe renal impairment was 42%, 80%, and 90% lower, respectively, than in patients with type 2 diabetes mellitus with normal renal function. The impact of hemodialysis on dapagliflozin exposure is not known [see DOSAGE AND ADMINISTRATION (2.3) , WARNINGS AND PRECAUTIONS (5.4) and USE IN SPECIFIC POPULATIONS (8.6) ] . Saxagliptin A single-dose, open-label study was conducted to evaluate the pharmacokinetics of saxagliptin (10 mg dose) in subjects with varying degrees of chronic renal impairment compared to subjects with normal renal function. The 10 mg dosage is not an approved dosage. The degree of renal impairment did not affect C max of saxagliptin or its metabolite. In subjects with moderate renal impairment (eGFR 30 to less than 45 mL/min/1.73 m 2 ), severe renal impairment (eGFR 15 to less than 30 mL/min/1.73 m 2 ) and ESRD patient on hemodialysis, the AUC values of saxagliptin or its active metabolite were > 2-fold higher than AUC values in subjects with normal renal function. QTERN is contraindicated in patients with an eGFR < 45 mL/min/1.73 m 2 . Hepatic Impairment Dapagliflozin In subjects with mild and moderate hepatic impairment (Child-Pugh classes A and B), mean C max and AUC of dapagliflozin were up to 12% and 36% higher, respectively, as compared to healthy matched control subjects following single-dose administration of 10 mg dapagliflozin. These differences were not considered to be clinically meaningful. In patients with severe hepatic impairment (Child-Pugh class C), mean C max and AUC of dapagliflozin were up to 40% and 67% higher, respectively, as compared to healthy matched controls [see USE IN SPECIFIC POPULATIONS (8.7) ] . Saxagliptin In subjects with hepatic impairment (Child-Pugh classes A, B, and C), mean C max and AUC of saxagliptin were up to 8% and 77% higher, respectively, compared to healthy matched controls following administration of a single 10 mg dose of saxagliptin. The 10 mg dosage is not an approved dosage. The corresponding C max and AUC of the active metabolite were up to 59% and 33% lower, respectively, compared to healthy matched controls. These differences are not considered to be clinically meaningful. Pediatric Pharmacokinetics of QTERN in the pediatric population has not been studied. Drug Interactions Saxagliptin and Dapagliflozin The lack of pharmacokinetic interaction between dapagliflozin and saxagliptin was demonstrated in a drug-drug interaction study between dapagliflozin and saxagliptin. Dapagliflozin In Vitro Assessment of Drug Interactions The metabolism of dapagliflozin is primarily via glucuronide conjugation mediated by UDP glucuronosyltransferase 1A9 (UGT1A9). In in vitro studies, dapagliflozin and dapagliflozin 3-O-glucuronide neither inhibited CYP 1A2, 2C9, 2C19, 2D6, or 3A4, nor induced CYP 1A2, 2B6, or 3A4. Dapagliflozin is a weak substrate of the P-glycoprotein (P‑gp) active transporter, and dapagliflozin 3-O-glucuronide is a substrate for the OAT3 active transporter. Dapagliflozin or dapagliflozin 3-O-glucuronide did not meaningfully inhibit P‑gp, OCT2, OAT1, or OAT3 active transporters. Overall, dapagliflozin is unlikely to affect the pharmacokinetics of concurrently administered medications that are P‑gp, OCT2, OAT1, or OAT3 substrates.

Therefore, saxagliptin is not expected to alter the metabolic clearance of coadministered drugs that are metabolized by these enzymes. Saxagliptin is a P-glycoprotein (P‑gp) substrate but is not a significant inhibitor or inducer of P‑gp.

Risk Summary There is no information regarding the presence of QTERN or its components (dapagliflozin and saxagliptin) in human milk, the effects on the breastfed infant, or the effects on milk production. Dapagliflozin and saxagliptin are present in the milk of lactating rats ( see Data ) . However, due to species-specific differences in lactation physiology, the clinical relevance of these data is not clear. 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 use of QTERN is not recommended while breastfeeding. Data Dapagliflozin Dapagliflozin was present at a milk/plasma ratio of 0.49, indicating that dapagliflozin and its metabolites are transferred into milk at a concentration that is approximately 50% of that in maternal plasma. Juvenile rats directly exposed to dapagliflozin showed a risk to the developing kidney (renal pelvic and tubular dilatations) during maturation. Saxagliptin Saxagliptin is secreted in the milk of lactating rats at approximately a 1:1 ratio with plasma drug concentrations.

QTERN is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Limitations of Use QTERN is not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus [ see WARNINGS AND PRECAUTIONS (5.1) ].

• Assess renal function before initiation of therapy and periodically thereafter. (2.1) • Take orally, once daily in the morning with or without food. (2.2) • For patients not already taking dapagliflozin, the recommended starting dose of QTERN is a 5 mg dapagliflozin/5 mg saxagliptin tablet once daily.

QTERN is contraindicated in patients with: • History of a serious hypersensitivity reaction to dapagliflozin or to saxagliptin, including anaphylactic reactions, angioedema or exfoliative skin conditions [see WARNINGS AND PRECAUTIONS (5.8) and ADVERSE REACTIONS (6.2) ] . • Moderate to severe renal impairment (eGFR less than 45 mL/min/1.73 m 2 ), end-stage renal disease (ESRD), or patients on dialysis [see USE IN SPECIFIC POPULATIONS (8.6) ] .

Table 3: Clinically Relevant Interactions with QTERN Strong Inhibitors of CYP3A4/5 Enzymes Clinical Impact Ketoconazole significantly increased saxagliptin exposure. Similar significant increases in plasma concentrations of saxagliptin are anticipated with other strong CYP3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin). Intervention Do not coadminister QTERN with strong cytochrome P450 3A4/5 inhibitors [see DOSAGE AND ADMINISTRATION (2.4 ) and CLINICAL PHARMACOLOGY (12.3) ] . Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when QTERN is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) [see WARNINGS AND PRECUATIONS (5.6) ] . Intervention Concomitant use may require lower doses of insulin or the insulin secretagogue to reduce the risk of hypoglycemia. Lithium Clinical Impact Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently during QTERN 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.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Safety and effectiveness of QTERN in pediatric patients under 18 years of age have not been established.

Because elderly patients are more likely to have decreased renal function, care should be taken when using QTERN in the elderly based on renal function [see DOSAGE AND ADMINISTRATION (2.3) ] . Dapagliflozin A total of 1424 (24%) of the 5936 dapagliflozin-treated patients were 65 years and older and 207 (3.5%) patients were 75 years and older in a pool of 21 double-blind, controlled, clinical studies assessing the efficacy of dapagliflozin in improving glycemic control. After controlling for level of renal function (eGFR), in clinical studies with dapagliflozin, efficacy was similar for patients under age 65 years and those 65 years and older. In patients 65 years and older, a higher proportion of patients treated with dapagliflozin had adverse reactions of hypotension [see WARNINGS AND PRECAUTIONS (5.4) ] . Saxagliptin In the seven double-blind, controlled clinical safety and efficacy trials of saxagliptin, a total of 4751 (42.0%) of the 11,301 patients randomized to saxagliptin were 65 years and over, and 1210 (10.7%) were 75 years and over. No overall differences in safety or effectiveness were observed between subjects ≥65 years old and younger subjects. While this clinical experience has not identified differences in responses between the elderly and younger patients, greater sensitivity of some older individuals cannot be ruled out.

QTERN No animal studies have been conducted with the combined products in QTERN to evaluate carcinogenesis, mutagenesis, or impairment of fertility. The following data are based on the findings in the studies with dapagliflozin and saxagliptin individually. Dapagliflozin Carcinogenesis Dapagliflozin did not induce tumors in either mice or rats at any of the doses evaluated in 2-year carcinogenicity studies. Oral doses in mice consisted of 5, 15, and 40 mg/kg/day in males and 2, 10, and 20 mg/kg/day in females, and oral doses in rats were 0.5, 2, and 10 mg/kg/day for both males and females. The highest doses evaluated in mice were approximately 72-times (males) and 105-times (females) the clinical dose of 10 mg per day, based on AUC exposure. In rats, the highest dose was approximately 131-times (males) and 186-times (females) the clinical dose of 10 mg per day, based on AUC exposure. Mutagenesis Dapagliflozin was negative in the Ames mutagenicity assay and was positive in a series of in vitro clastogenicity assays in the presence of S9 activation and at concentrations greater than or equal to 100 µg/mL. Dapagliflozin was negative for clastogenicity in a series of in vivo studies evaluating micronuclei or DNA repair in rats at exposure multiples greater than 2100-times the clinical dose. Impairment of Fertility Dapagliflozin had no effects on mating, fertility, or early embryonic development in treated male or female rats at exposure multiples less than or equal to 1708-times and 998-times the maximum recommended human dose in males and females, respectively. Saxagliptin Carcinogenesis Carcinogenicity was evaluated in 2-year studies conducted in CD-1 mice and Sprague-Dawley rats. Saxagliptin did not increase the incidence of tumors in mice dosed orally at 50, 250, and 600 mg/kg up to 870-times (males) and 1165-times (females) the 5 mg/day clinical dose, based on AUC. Saxagliptin did not increase the incidence of tumors in rats dosed orally at 25, 75, 150, and 300 mg/kg up to 355-times (males) and 2217-times (females) the 5 mg/day clinical dose, based on AUC. Mutagenesis Saxagliptin was not mutagenic or clastogenic in a battery of genotoxicity tests (Ames bacterial mutagenesis, human and rat lymphocyte cytogenetics, rat bone marrow micronucleus and DNA repair assays). The active metabolite of saxagliptin was not mutagenic in an Ames bacterial assay. Impairment of Fertility Saxagliptin administered to rats had no effect on fertility or the ability to maintain a litter at exposures up to 603-times and 776-times the 5 mg clinical dose in males and females, based on AUC.

The following important adverse reactions are described below or elsewhere in the labeling: • Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis [see WARNINGS AND PRECAUTIONS (5.1) ] • Pancreatitis [see WARNINGS AND PRECAUTIONS (5.2) ] • Heart Failure [see WARNINGS AND PRECAUTIONS (5.3) ] • Volume Depletion [see WARNINGS AND PRECAUTIONS (5.4) ] • Urosepsis and Pyelonephritis [see WARNINGS AND PRECAUTIONS (5.5) ] • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues [see WARNINGS AND PRECAUTIONS (5.6) ] • Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene) [see WARNINGS AND PRECAUTIONS (5.7) ] • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS (5.8) ] • Genital Mycotic Infections [see WARNINGS AND PRECAUTIONS (5.9) ] • Severe and Disabling Arthralgia [see WARNINGS AND PRECAUTIONS (5.10) ] • Bullous Pemphigoid [see WARNINGS AND PRECAUTIONS (5.11) ]

In the event of an overdose, contact the Poison Control Center. Appropriate supportive treatment should be initiated as dictated by the patient’s clinical status. The removal of dapagliflozin by hemodialysis has not been studied. Saxagliptin and its major metabolite can be removed by hemodialysis (23% of dose over 4 hours).

QTERN tablets for oral use contain dapagliflozin and saxagliptin. Dapagliflozin propanediol is an active inhibitor of sodium‑glucose cotransporter 2 (SGLT2). It is described chemically as D‑glucitol, 1,5‑anhydro‑1‑C‑[4‑chloro‑3‑[(4‑ethoxyphenyl)methyl]phenyl] ‑, (1 S )‑. Dapagliflozin is compounded with (2 S )‑1,2‑propanediol, hydrate (1:1:1) with an empirical formula as C 21 H 25 ClO 6 •C 3 H 8 O 2 •H 2 O and the molecular weight of 502.98. The structural formula is: Saxagliptin is an active inhibitor of the dipeptidyl‑peptidase‑4 (DPP‑4) enzyme. It is isolated in the monohydrate form chemically known as (1 S ,3 S ,5 S )‑2‑[(2 S )‑2‑amino‑2‑(3‑hydroxytricyclo [3.3.1.1] dec‑1‑yl)acetyl] ‑2‑azabicyclo[3.1.0]hexane‑3‑carbonitrile, monohydrate or (1 S ,3 S ,5 S )‑2‑[(2 S )‑2‑amino‑2‑(3‑hydroxy‑1‑adamantan‑1‑yl)acetyl]‑2‑azabicyclo[3.1.0] hexane‑3‑carbonitrile hydrate. The empirical formula is C 18 H 25 N 3 O 2 •H 2 O and the molecular weight is 333.43. The structural formula is: QTERN is available as film-coated tablets of two strengths: • 5 mg dapagliflozin/5 mg saxagliptin. Each tablet contains 5 mg dapagliflozin (equivalent to 6.15 mg dapagliflozin propanediol) and 5 mg saxagliptin (exists in the form of HCl salt). • 10 mg dapagliflozin/5 mg saxagliptin. Each tablet contains 10 mg dapagliflozin (equivalent to 12.3 mg dapagliflozin propanediol) and 5 mg saxagliptin (exists in the form of HCl salt). Each tablet also contains the following inactive ingredients: anhydrous lactose, croscarmellose sodium, iron oxides, magnesium stearate, microcrystalline cellulose, polyvinyl alcohol, polyethylene glycol, silicon dioxide, talc, and titanium dioxide. Hydrochloric acid and sodium hydroxide (if needed) are added for pH adjustment.

Saxagliptin Saxagliptin produced adverse skin changes in the extremities of cynomolgus monkeys (scabs and/or ulceration of tail, digits, scrotum, and/or nose). Skin lesions were reversible within exposure approximately 20-times the 5 mg clinical dose, but in some cases were irreversible and necrotizing at higher exposures. Adverse skin changes were not observed at exposures similar to (1- to 3-times) the 5 mg clinical dose. Clinical correlates to skin lesions in monkeys have not been observed in human clinical trials of saxagliptin.

The dapagliflozin and saxagliptin in combination with metformin has been studied in adult patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin in the following studies. Treatment with dapagliflozin and saxagliptin and metformin (combination or add-on therapy) at all doses produced statistically significant improvements in HbA1c compared to the active comparator or placebo study arms in combination with metformin.

Risk Summary Based on animal data showing adverse renal effects from dapagliflozin, QTERN is not recommended during the second and third trimesters of pregnancy. The limited available data with QTERN or its components (dapagliflozin and saxagliptin) in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. 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 tubular dilatations, that were not fully reversible, were observed in rats when dapagliflozin (a component of QTERN) was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy, at all doses tested; the lowest of which provided an exposure 15-times the 10 mg clinical dose ( see Data ) . No adverse developmental effects were observed when saxagliptin was administered to pregnant rats and rabbits (see Data ) . The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with an HbA1c greater than 7% and has been reported to be as high as 20 to 25% in women with an HbA1c greater than 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 embryofetal risk 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 Dapagliflozin Dapagliflozin dosed directly to juvenile rats from postnatal day (PND) 21 until PND 90 at doses of 1, 15, or 75 mg/kg/day, increased kidney weights and increased the incidence of renal pelvic and tubular dilatations at all dose levels. Exposure at the lowest dose was 15-times the 10 mg clinical dose (based on AUC). The renal pelvic and tubular dilatations observed in juvenile animals did not fully reverse within a 1-month recovery period. In a prenatal and postnatal development study, dapagliflozin was administered to maternal rats from gestation Day 6 through lactation Day 21 at doses of 1, 15, or 75 mg/kg/day, and pups were indirectly exposed in utero and throughout lactation. Increased incidence or severity of renal pelvic dilatation was observed in 21 day-old pup offspring of treated dams at 75 mg/kg/day (maternal and pup dapagliflozin exposures were 1415-times and 137-times, respectively, the human values at the 10 mg clinical dose, based on AUC). Dose-related reductions in pup body weights were observed at greater than or equal to 29-times the 10 mg clinical dose (based on AUC). No adverse effects on developmental endpoints were noted at 1 mg/kg/day, (19-times the 10 mg clinical dose, based on AUC). These outcomes occurred with drug exposure during periods of renal development in rats that corresponds to the late second and third trimester of human development. In embryofetal development studies in rats and rabbits, dapagliflozin was administered throughout organogenesis, corresponding to the first trimester of human pregnancy. In rats, dapagliflozin was neither embryolethal nor teratogenic at doses up to 75 mg/kg/day (1441-times the 10 mg clinical dose, based on AUC). Dose-related effects on the rat fetus (structural abnormalities and reduced body weight) occurred only at higher dosages, equal to or greater than 150 mg/kg (more than 2344-times the 10 mg clinical dose, based on AUC), which were associated with maternal toxicity. No developmental toxicities were observed in rabbits at doses up to 180 mg/kg/day (1191-times the 10 mg clinical dose, based on AUC). Saxagliptin In embryofetal development studies, saxagliptin was administered to pregnant rats and rabbits during the period of organogenesis, corresponding to the first trimester of human pregnancy. No adverse developmental effects were observed in either species at exposures 1503- and 152-times the 5 mg clinical dose in rats and rabbits, respectively, based on AUC. Saxagliptin crosses the placenta into the fetus following dosing in pregnant rats. In a prenatal and postnatal development study, no adverse developmental effects were observed in maternal rats administered saxagliptin from gestation day 6 through lactation day 21 at exposures up to 470-times the 5 mg clinical dose, based on AUC.

Assess renal function prior to initiation of QTERN therapy and periodically thereafter [see WARNINGS AND PRECAUTIONS (5.4) ] . Assess volume status. In patients with volume depletion, correct this condition before initiating QTERN [see WARNINGS AND PRECAUTIONS (5.4) and USE IN SPECIFIC POPULATIONS (8.5,   8.6) ] .

MEDICATION GUIDE QTERN ® [CUE-turn] (dapagliflozin and saxagliptin) tablets, for oral use What is the most important information I should know about QTERN? Serious side effects can happen to people taking QTERN, including: • • Diabetic Ketoacidosis (increased ketones in your blood or urine) in people with type 1 diabetes and other ketoacidosis. QTERN can cause ketoacidosis that can be life-threatening and may lead to death. Ketoacidosis is a serious condition which needs to be treated in a hospital. People with type 1 diabetes have a high risk of getting ketoacidosis. People with type 2 diabetes or pancreas problems also have an increased risk of getting ketoacidosis. Ketoacidosis can also happen in people who are sick, cannot eat or drink as usual, skip meals, are on a diet high in fat and low in carbohydrates (ketogenic diet), take less than the usual amount of insulin or miss insulin doses, drink too much alcohol, have a loss of too much fluid from the body (volume depletion), or who have surgery. Ketoacidosis can happen even if your blood sugar is less than 250 mg/dL. Your healthcare provider may ask you to periodically check ketones in your urine or blood.   Stop taking QTERN and call your healthcare provider or get medical help right away if you get any of the following. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL. ∘ nausea ∘ vomiting ∘ stomach area (abdominal) pain ∘ tiredness ∘ trouble breathing ∘ ketones in your urine or blood • Inflammation of the pancreas (pancreatitis). Saxagliptin, one of the medicines in QTERN, can cause inflammation of the pancreas, which may be severe and lead to death. Certain medical problems make you more likely to get pancreatitis. Before you start taking QTERN, tell your healthcare provider if you have ever had: ∘ inflammation of your pancreas (pancreatitis) ∘ stones in your gallbladder (gallstones) ∘ a history of alcoholism ∘ high blood triglyceride levels   It is not known if having these medical problems will make you more likely to get pancreatitis with QTERN. Stop taking QTERN and contact your healthcare provider right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis. • Heart failure. Heart failure means your heart does not pump blood well enough. Before you start taking QTERN, tell your healthcare provider if you have ever had heart failure or have problems with your kidneys. Contact your healthcare provider right away if you have any of the following symptoms: ∘ increasing shortness of breath or trouble breathing, especially when you lie down ∘ swelling or fluid retention, especially in the feet, ankles, or legs ∘ an unusually fast increase in weight ∘ unusual tiredness   These may be symptoms of heart failure. • Dehydration. QTERN 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 in people with Type 2 diabetes who are taking dapagliflozin, a component of QTERN. You may be at a higher risk of dehydration if you: ∘ take medicines to lower your blood pressure, including water pills (diuretics) ∘ are on a low salt diet ∘ have kidney problems ∘ are 65 years of age or older   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. What is QTERN? QTERN is a prescription medicine that contains dapagliflozin and saxagliptin. QTERN is used along with diet and exercise to improve blood sugar (glucose) control in adults with type 2 diabetes. • QTERN is not for use to improve blood sugar (glucose) control in people with type 1 diabetes. • It is not known if QTERN is safe and effective in children younger than 18 years of age. Who should not take QTERN? Do not take QTERN if you: • are allergic to dapagliflozin, saxagliptin, or any of the ingredients in QTERN. See the end of this Medication Guide for a list of ingredients in QTERN. Symptoms of a serious allergic reaction to QTERN may include: ∘ swelling of the face, lips, throat and other areas of your skin ∘ difficulty with swallowing or breathing ∘ rash, itching, flaking, or peeling ∘ raised red areas on your skin (hives)   If you have any of these symptoms, stop taking QTERN and contact your healthcare provider or go to the nearest hospital emergency room right away. • have moderate to severe kidney problems or are on dialysis. Before taking QTERN, tell your healthcare provider about all of your medical conditions, including if you: • have type 1 diabetes or have had diabetic ketoacidosis (increased ketones in your blood or urine). • have a decrease in your insulin dose. • have a serious infection. • have a history of infection of the vagina or penis. • have kidney problems. • have liver problems. • have a history of urinary tract infections or problems with urination. • are on a low sodium (salt) diet. Your healthcare provider may ask you to change your diet. • are going to have surgery. Your healthcare provider may stop your QTERN before you have surgery. Talk to your healthcare provider if you are having surgery about when to stop taking QTERN and when to start it again. • are eating less or there is a change in your diet. • are dehydrated. • 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 in the short term (“binge” drinking). • have heart problems, including heart failure. • have had a history of swelling of the face, lips, tongue and throat (angioedema) when you have taken a dipeptidyl peptidase 4 (DPP-4) inhibitor like saxagliptin one of the medicines in QTERN. If you are not sure that you have taken this medicine before, ask your healthcare provider. • are pregnant or plan to become pregnant. QTERN may harm your unborn baby. If you are pregnant or plan to become pregnant, talk to your healthcare provider about the best way to control your blood sugar. • are breastfeeding or plan to breastfeed. It is not known if QTERN passes into your breast milk. Talk with your healthcare provider about the best way to feed your baby if you are taking QTERN. Breastfeeding is not recommended while taking QTERN. Tell your healthcare provider about all the medicines you take , including prescription and over-the-counter medicines, vitamins, and herbal supplements. QTERN may affect the way other medicines work, and other medicines may affect how QTERN works. Contact your healthcare provider if you will be starting or stopping certain other types of medicines such as antibiotics or medicines that treat fungus or HIV/AIDS, because your dose of QTERN might need to be changed. Know the medicines you take. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine. How should I take QTERN? • Take QTERN exactly as your healthcare provider tells you to take it. • Take QTERN by mouth 1 time each day in the morning with or without food. • Your healthcare provider will tell you how much QTERN to take and when to take it. Your healthcare provider may change your dose if needed. • Swallow QTERN whole. Do not crush, cut or chew QTERN tablets. • If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take 2 doses of QTERN at the same time unless your healthcare provider tells you to do so. Talk to your healthcare provider if you have questions about a missed dose. • If you take too much QTERN, call your healthcare provider, or go to the nearest hospital emergency room right away. • During periods of stress on the body, such as fever, trauma, infection, or surgery, the amount of diabetes medicine you need may change. Tell your healthcare provider right away if you have any of these conditions and follow your healthcare provider’s instructions. • Your healthcare provider may tell you to take QTERN along with other diabetes medicines. Low blood sugar can happen more often when QTERN is taken with certain other diabetes medicines. See “ What are the possible side effects of QTERN? ”. • QTERN will cause your urine to test positive for glucose. • Your healthcare provider may do certain blood tests before you start QTERN and during treatment as needed. Your healthcare provider may change your dose of QTERN based on the results of your blood tests. What are the possible side effects of QTERN? QTERN may cause serious side effects, including: • See “What is the most important information I should know about QTERN?”. • Serious urinary tract infections. Serious urinary tract infections that may lead to hospitalization have happened in people who are taking dapagliflozin. 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 QTERN with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, this can increase your risk of getting low blood sugar. Tell your healthcare provider if you take other diabetes medicines. Signs and symptoms of low blood sugar may include: ∘ headache ∘ confusion ∘ hunger ∘ shaking or feeling jittery ∘ drowsiness ∘ dizziness ∘ fast heartbeat ∘ weakness ∘ sweating ∘ irritability • 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).

Dapagliflozin Sodium-glucose cotransporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Dapagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, dapagliflozin reduces reabsorption of filtered glucose and thereby promotes urinary glucose excretion. Saxagliptin Increased concentrations of the incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the bloodstream from the small intestine in response to meals. These hormones cause insulin release from the pancreatic beta cells in a glucose-dependent manner but are inactivated by the DPP-4 enzyme within minutes. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, reducing hepatic glucose production. In patients with type 2 diabetes mellitus, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved. Saxagliptin is a competitive DPP-4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 diabetes mellitus.

Dapagliflozin Increases in the amount of glucose excreted in the urine were observed in healthy subjects and in patients with type 2 diabetes mellitus following the administration of dapagliflozin. Dapagliflozin dose of 5 or 10 mg per day in patients with type 2 diabetes mellitus for 12 weeks resulted in excretion of approximately 70 grams of glucose in the urine per day at Week 12. A near maximum glucose excretion was observed at the dapagliflozin daily dose of 20 mg. This urinary glucose excretion with dapagliflozin also results in increases in urinary volume [see ADVERSE REACTIONS (6.1) ] . After discontinuation of dapagliflozin, on average, the elevation in urinary glucose excretion approaches baseline by about 3 days from discontinuation for the 10 mg dose. Figure 1: Scatter Plot and Fitted Line of Change from Baseline in 24-Hour Urinary Glucose Amount versus Dapagliflozin Dose in Healthy Subjects and Subjects with Type 2 Diabetes Mellitus (T2DM) (Semi-Log Plot) Saxagliptin In patients with type 2 diabetes mellitus, administration of saxagliptin inhibits DPP-4 enzyme activity for a 24-hour period. After an oral glucose load or a meal, this DPP-4 inhibition resulted in a 2- to 3-fold increase in circulating levels of active GLP-1 and GIP, decreased glucagon concentrations, and increased glucose-dependent insulin secretion from pancreatic beta cells. The rise in insulin and decrease in glucagon were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal. Cardiac Electrophysiology Dapagliflozin Dapagliflozin was not associated with clinically meaningful prolongation of QTc interval at daily doses up to 150 mg (15-times the recommended maximum dose) in a study of healthy subjects. In addition, no clinically meaningful effect on QTc interval was observed following single doses of up to 500 mg (50-times the recommended maximum daily dose) of dapagliflozin in healthy subjects. Saxagliptin In a randomized, double-blind, placebo-controlled, 4-way crossover, active comparator study using moxifloxacin in 40 healthy subjects, saxagliptin was not associated with clinically meaningful prolongation of the QTc interval or heart rate at daily doses up to 40 mg (8-times the recommended maximum daily dose).

Overall, the pharmacokinetics of dapagliflozin and saxagliptin were not affected in a clinically relevant manner when administered as QTERN. Saxagliptin The pharmacokinetics of saxagliptin and its active metabolite, 5-hydroxy saxagliptin, were similar in healthy subjects and in patients with type 2 diabetes mellitus. The C max and AUC values of saxagliptin and its active metabolite increased proportionally in the 2.5 to 400 mg dose range. Following a 5 mg single oral dose of saxagliptin to healthy subjects, the mean plasma AUC values for saxagliptin and its active metabolite were 78 ng•h/mL and 214 ng•h/mL, respectively. The corresponding plasma C max values were 24 ng/mL and 47 ng/mL, respectively. The average variability (%CV) for AUC and C max for both saxagliptin and its active metabolite was less than 25%. No appreciable accumulation of either saxagliptin or its active metabolite was observed with repeated once daily dosing at any dose level. No dose- and time-dependence were observed in the clearance of saxagliptin and its active metabolite over 14 days of once daily dosing with saxagliptin at doses ranging from 2.5 to 400 mg. Absorption Dapagliflozin Following oral administration of dapagliflozin, the maximum plasma concentration (C max ) is usually attained within 2 hours under fasting state. The C max and AUC values increase dose proportionally with increase in dapagliflozin dose in the therapeutic dose range. The absolute oral bioavailability of dapagliflozin following the administration of a 10 mg dose is 78%. Administration of dapagliflozin with a high-fat meal decreases its C max by up to 50% and prolongs T max by approximately 1 hour but does not alter AUC as compared with the fasted state. Saxagliptin The median time to maximum concentration (T max ) following the 5 mg once daily dose was 2 hours for saxagliptin and 4 hours for its active metabolite. Administration with a high-fat meal resulted in an increase in T max of saxagliptin by approximately 20 minutes as compared to fasted conditions. There was a 27% increase in the AUC of saxagliptin when given with a meal as compared to fasted conditions. Distribution Dapagliflozin Dapagliflozin is approximately 91% protein bound. Protein binding is not altered in patients with renal or hepatic impairment. Saxagliptin The in vitro protein binding of saxagliptin and its active metabolite in human serum is negligible. Therefore, changes in blood protein levels in various disease states (e.g., renal or hepatic impairment) are not expected to alter the disposition of saxagliptin. Metabolism Dapagliflozin The metabolism of dapagliflozin is primarily mediated by UGT1A9; CYP-mediated metabolism is a minor clearance pathway in humans. Dapagliflozin is extensively metabolized, primarily to yield dapagliflozin 3-O-glucuronide, which is an inactive metabolite. Dapagliflozin 3-O-glucuronide accounted for 61% of a 50 mg [ 14 C]-dapagliflozin dose and is the predominant drug-related component in human plasma. Saxagliptin The metabolism of saxagliptin is primarily mediated by cytochrome P450 3A4/5 (CYP3A4/5). The major metabolite of saxagliptin is also a DPP-4 inhibitor, which is one-half as potent as saxagliptin. Therefore, strong CYP3A4/5 inhibitors and inducers will alter the pharmacokinetics of saxagliptin and its active metabolite [see DRUG INTERACTIONS (7) ] . Elimination Dapagliflozin Dapagliflozin and related metabolites are primarily eliminated via the renal pathway. Following a single 50 mg dose of [ 14 C]-dapagliflozin, 75% and 21% total radioactivity is excreted in urine and feces, respectively. In urine, less than 2% of the dose is excreted as parent drug. In feces, approximately 15% of the dose is excreted as parent drug. The mean plasma terminal half-life (t 1/2 ) for dapagliflozin is approximately 12.9 hours following a single oral dose of dapagliflozin 10 mg. Saxagliptin Saxagliptin is eliminated by both renal and hepatic pathways. Following a single 50 mg dose of [ 14 C]-saxagliptin, 24%, 36%, and 75% of the dose was excreted in the urine as saxagliptin, its active metabolite, and total radioactivity, respectively. The average renal clearance of saxagliptin (~230 mL/min) was greater than the average estimated glomerular filtration rate (~120 mL/min), suggesting some active renal excretion. A total of 22% of the administered radioactivity was recovered in feces representing the fraction of the saxagliptin dose excreted in bile and/or unabsorbed drug from the gastrointestinal tract. Following a single oral dose of saxagliptin 5 mg to healthy subjects, the mean plasma terminal half-life (t 1/2 ) for saxagliptin and its active metabolite was 2.5 and 3.1 hours, respectively. Specific Populations Effects of Age, Gender, Race and Body Weight on Pharmacokinetics Based on a population pharmacokinetic analysis, age, gender, race, and body weight do not have a clinically meaningful effect on the pharmacokinetics of saxagliptin and dapagliflozin. Renal Impairment Dapagliflozin At steady state (20 mg once daily dapagliflozin for 7 days), patients with type 2 diabetes mellitus with mild, moderate, or severe renal impairment (as determined by eGFR) had geometric mean systemic exposures of dapagliflozin that were 45%, 100%, and 200% higher, respectively, as compared to patients with type 2 diabetes mellitus with normal renal function. Higher systemic exposure of dapagliflozin in patients with type 2 diabetes mellitus with renal impairment did not result in a correspondingly higher 24-hour urinary glucose excretion. The steady-state 24-hour urinary glucose excretion in patients with type 2 diabetes mellitus and mild, moderate, and severe renal impairment was 42%, 80%, and 90% lower, respectively, than in patients with type 2 diabetes mellitus with normal renal function. The impact of hemodialysis on dapagliflozin exposure is not known [see DOSAGE AND ADMINISTRATION (2.3) , WARNINGS AND PRECAUTIONS (5.4) and USE IN SPECIFIC POPULATIONS (8.6) ] . Saxagliptin A single-dose, open-label study was conducted to evaluate the pharmacokinetics of saxagliptin (10 mg dose) in subjects with varying degrees of chronic renal impairment compared to subjects with normal renal function. The 10 mg dosage is not an approved dosage. The degree of renal impairment did not affect C max of saxagliptin or its metabolite. In subjects with moderate renal impairment (eGFR 30 to less than 45 mL/min/1.73 m 2 ), severe renal impairment (eGFR 15 to less than 30 mL/min/1.73 m 2 ) and ESRD patient on hemodialysis, the AUC values of saxagliptin or its active metabolite were > 2-fold higher than AUC values in subjects with normal renal function. QTERN is contraindicated in patients with an eGFR < 45 mL/min/1.73 m 2 . Hepatic Impairment Dapagliflozin In subjects with mild and moderate hepatic impairment (Child-Pugh classes A and B), mean C max and AUC of dapagliflozin were up to 12% and 36% higher, respectively, as compared to healthy matched control subjects following single-dose administration of 10 mg dapagliflozin. These differences were not considered to be clinically meaningful. In patients with severe hepatic impairment (Child-Pugh class C), mean C max and AUC of dapagliflozin were up to 40% and 67% higher, respectively, as compared to healthy matched controls [see USE IN SPECIFIC POPULATIONS (8.7) ] . Saxagliptin In subjects with hepatic impairment (Child-Pugh classes A, B, and C), mean C max and AUC of saxagliptin were up to 8% and 77% higher, respectively, compared to healthy matched controls following administration of a single 10 mg dose of saxagliptin. The 10 mg dosage is not an approved dosage. The corresponding C max and AUC of the active metabolite were up to 59% and 33% lower, respectively, compared to healthy matched controls. These differences are not considered to be clinically meaningful. Pediatric Pharmacokinetics of QTERN in the pediatric population has not been studied. Drug Interactions Saxagliptin and Dapagliflozin The lack of pharmacokinetic interaction between dapagliflozin and saxagliptin was demonstrated in a drug-drug interaction study between dapagliflozin and saxagliptin. Dapagliflozin In Vitro Assessment of Drug Interactions The metabolism of dapagliflozin is primarily via glucuronide conjugation mediated by UDP glucuronosyltransferase 1A9 (UGT1A9). In in vitro studies, dapagliflozin and dapagliflozin 3-O-glucuronide neither inhibited CYP 1A2, 2C9, 2C19, 2D6, or 3A4, nor induced CYP 1A2, 2B6, or 3A4. Dapagliflozin is a weak substrate of the P-glycoprotein (P‑gp) active transporter, and dapagliflozin 3-O-glucuronide is a substrate for the OAT3 active transporter. Dapagliflozin or dapagliflozin 3-O-glucuronide did not meaningfully inhibit P‑gp, OCT2, OAT1, or OAT3 active transporters. Overall, dapagliflozin is unlikely to affect the pharmacokinetics of concurrently administered medications that are P‑gp, OCT2, OAT1, or OAT3 substrates.

Therefore, saxagliptin is not expected to alter the metabolic clearance of coadministered drugs that are metabolized by these enzymes. Saxagliptin is a P-glycoprotein (P‑gp) substrate but is not a significant inhibitor or inducer of P‑gp.

Risk Summary There is no information regarding the presence of QTERN or its components (dapagliflozin and saxagliptin) in human milk, the effects on the breastfed infant, or the effects on milk production. Dapagliflozin and saxagliptin are present in the milk of lactating rats ( see Data ) . However, due to species-specific differences in lactation physiology, the clinical relevance of these data is not clear. 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 use of QTERN is not recommended while breastfeeding. Data Dapagliflozin Dapagliflozin was present at a milk/plasma ratio of 0.49, indicating that dapagliflozin and its metabolites are transferred into milk at a concentration that is approximately 50% of that in maternal plasma. Juvenile rats directly exposed to dapagliflozin showed a risk to the developing kidney (renal pelvic and tubular dilatations) during maturation. Saxagliptin Saxagliptin is secreted in the milk of lactating rats at approximately a 1:1 ratio with plasma drug concentrations.
