ONGLYZA

Saxagliptin is an orally-active inhibitor of the DPP-4 enzyme. Saxagliptin monohydrate is described chemically as (1 S ,3 S ,5 S )-2-[(2 S )-2-Amino-2-(3-hydroxytricyclo[3.3.1.1 3,7 ]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-hydroxyadamantan-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: Saxagliptin monohydrate is a white to light yellow or light brown, non-hygroscopic, crystalline powder. It is sparingly soluble in water at 24°C ± 3°C, slightly soluble in ethyl acetate, and soluble in methanol, ethanol, isopropyl alcohol, acetonitrile, acetone, and polyethylene glycol 400 (PEG 400). Each film-coated tablet of ONGLYZA for oral use contains either 2.79 mg saxagliptin hydrochloride (anhydrous) equivalent to 2.5 mg saxagliptin or 5.58 mg saxagliptin hydrochloride (anhydrous) equivalent to 5 mg saxagliptin and the following inactive ingredients: croscarmellose sodium, lactose monohydrate, magnesium stearate and microcrystalline cellulose. In addition, the film coating contains the following inactive ingredients: iron oxides, polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide. Saxagliptin Chemical Structure

ONGLYZA is a dipeptidyl peptidase-4 (DPP-4) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. (1.1) Limitations of use: • Not recommended for the treatment of type 1 diabetes mellitus or diabetic ketoacidosis. (1.2) 1.1 Monotherapy and Combination Therapy ONGLYZA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus [ see Clinical Studies (14) ]. 1.2 Limitations of Use ONGLYZA is not recommended for the treatment of type 1 diabetes mellitus or diabetic ketoacidosis. 1.1 Monotherapy and Combination Therapy ONGLYZA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus [ see Clinical Studies (14) ].

• Recommended dosage is 2.5 mg or 5 mg orally once daily taken regardless of meals. (2.1) • Patients with an eGFR <45 mL/min/1.73 m2 (moderate or severe renal impairment, or end-stage renal disease): Recommended dosage is 2.5 mg once daily regardless of meals. (2.2) • Assess renal function before starting ONGLYZA and periodically thereafter. (2.2) • Limit the dosage of ONGLYZA to 2.5 mg daily for patients also taking strong cytochrome P450 3A4/5 (CYP3A4/5) inhibitors (e.g., ketoconazole). (2.3) 2.1 Recommended Dosage The recommended dosage of ONGLYZA is 2.5 mg or 5 mg orally once daily taken regardless of meals. Do not cut, crush, or chew ONGLYZA tablets. If a dose is missed, advise patients not to take an extra dose. Resume treatment with the next dose. 2.2 Dosage in Patients with Renal Impairment Assess renal function prior to initiation of ONGLYZA and then as clinically indicated [see Use in Specific Populations (8.6) ]. The recommended dosage of ONGLYZA in patients with an eGFR greater than or equal to 45 mL/minute/1.73 m 2 is the same as the recommended dosage in patients with normal renal function [ see Dosage and Administration (2.1) ]. The dosage of ONGLYZA is 2.5 mg orally once daily for patients with eGFR <45 mL/min/1.73 m 2 [which includes a subset of moderate or severe renal impairment, or with end-stage renal disease (ESRD) requiring hemodialysis] [ see Clinical Pharmacology (12.3) and Clinical Studies (14.2) ]. ONGLYZA should be administered following hemodialysis. ONGLYZA has not been studied in patients undergoing peritoneal dialysis. 2.3 Dosage Modification with Concomitant Use of Strong CYP3A4/5 Inhibitors The dosage of ONGLYZA is 2.5 mg orally once daily when used concomitantly with strong cytochrome P450 3A4/5 (CYP3A4/5) inhibitors (e.g., ketoconazole, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin) [ see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ].

ONGLYZA is contraindicated in patients with a history of a serious hypersensitivity reaction to saxagliptin or any of the ingredients in ONGLYZA. Reactions such as anaphylaxis, angioedema, or exfoliative skin conditions have been reported with ONGLYZA [ see Warnings and Precautions (5.4) and Adverse Reactions (6.2) ]. • History of a serious hypersensitivity reaction (e.g., anaphylaxis, angioedema, exfoliative skin conditions) to saxagliptin or any of the ingredients in ONGLYZA. (4)

The following serious adverse reactions are described below or elsewhere in the prescribing information: • Pancreatitis [ see Warnings and Precautions (5.1) ] • Heart Failure [ see Warnings and Precautions (5.2) ] • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues [ see Warnings and Precautions (5.3) ] • Hypersensitivity Reactions [ see Warnings and Precautions (5.4) ] • Severe and disabling arthralgia [ see Warnings and Precautions (5.5) ] • Bullous pemphigoid [ see Warnings and Precautions (5.6) ] • Most common adverse reactions (incidence ≥5% and more often than placebo) are upper respiratory tract infection, urinary tract infection, and headache. (6.1) • Peripheral edema was reported more commonly in patients treated with the combination of ONGLYZA and a thiazolidinedione (TZD) than in patients treated with the combination of placebo and TZD.

Adverse Reactions in Placebo-Controlled Trials in Adults with Type 2 Diabetes Mellitus The data in Table 1 are derived from a pool of 5 placebo-controlled clinical trials [ see Clinical Studies (14) ]. These data shown in the table reflect exposure of 882 patients to ONGLYZA and a mean duration of exposure to ONGLYZA of 21 weeks. The mean age of these patients was 55 years, 1.4 % were 75 years of age or older and 48.4% were male. The population was 67.5% White, 4.6% Black or African American, 17.4% Asian, 10.5% other races and 9.8% were of Hispanic or Latino ethnicity. At baseline the population had type 2 diabetes mellitus for an average of 5.2 years and a mean HbA1c of 8.2%. Baseline estimated renal function was normal or mildly impaired (eGFR≥60 mL/min/1.73 m 2 ) in 91% of these patients. Table 1 shows common adverse reactions, excluding hypoglycemia, associated with the use of ONGLYZA. These adverse reactions occurred more commonly on ONGLYZA than on placebo and occurred in at least 5% of patients treated with ONGLYZA. Table 1: Adverse Reactions in Placebo-Controlled Trials The 5 placebo-controlled trials include two monotherapy trials and one add-on combination therapy trial with each of the following: metformin hydrochloride (HCl), thiazolidinedione, or glyburide. Table shows 24-week data regardless of glycemic rescue. Reported in ≥5% of Patients Treated with ONGLYZA 5 mg and More Commonly than in Patients Treated with Placebo % of Patients ONGLYZA 5 mg N=882 Placebo N=799 Upper respiratory tract infection 7.7 7.6 Urinary tract infection 6.8 6.1 Headache 6.5 5.9 In patients treated with ONGLYZA 2.5 mg, headache (6.5%) was the only adverse reaction reported at a rate ≥5% and more commonly than in patients treated with placebo. In the add-on to TZD trial, the incidence of peripheral edema was higher for ONGLYZA 5 mg versus placebo (8.1% and 4.3%, respectively). The incidence of peripheral edema for ONGLYZA 2.5 mg was 3.1%. None of the reported adverse reactions of peripheral edema resulted in trial drug discontinuation. Rates of peripheral edema for ONGLYZA 2.5 mg and ONGLYZA 5 mg versus placebo were 3.6% and 2% versus 3% given as monotherapy, 2.1% and 2.1% versus 2.2% given as add-on therapy to metformin HCl, and 2.4% and 1.2% versus 2.2% given as add-on therapy to glyburide. The incidence rate of fractures was 1.0 and 0.6 per 100 patient-years, respectively, for ONGLYZA (pooled analysis of 2.5 mg, 5 mg, and 10 mg) and placebo. The 10 mg dosage is not an approved dosage. The incidence rate of fracture events in patients who received ONGLYZA did not increase over time. Causality has not been established and nonclinical studies have not demonstrated adverse effects of ONGLYZA on bone. An event of thrombocytopenia, consistent with a diagnosis of idiopathic thrombocytopenic purpura, was observed in the clinical program. The relationship of this event to ONGLYZA is not known. Discontinuation of therapy due to adverse reactions occurred in 2.2%, 3.3%, and 1.8% of patients receiving ONGLYZA 2.5 mg, ONGLYZA 5 mg, and placebo, respectively. The most common adverse reactions (reported in at least 2 patients treated with ONGLYZA 2.5 mg or at least 2 patients treated with ONGLYZA 5 mg) associated with premature discontinuation of therapy included lymphopenia (0.1% and 0.5% versus 0%, respectively), rash (0.2% and 0.3% versus 0.3%), blood creatinine increased (0.3% and 0% versus 0%), and blood creatine phosphokinase increased (0.1% and 0.2% versus 0%). Adverse Reactions with Concomitant Use with Insulin In the add-on to insulin trial [ see Clinical Studies (14.1) ], the incidence of adverse reactions, including serious adverse reactions and discontinuations due to adverse reactions, was similar between ONGLYZA and placebo, except for confirmed hypoglycemia [ see Adverse Reactions (6.1) ]. Hypoglycemia Adverse reactions of hypoglycemia were based on all reports of hypoglycemia. A concurrent glucose measurement was not required or was normal in some patients. Therefore, it is not possible to conclusively determine that all these reports reflect true hypoglycemia. In the add-on to glyburide trial, the overall incidence of reported hypoglycemia was higher for ONGLYZA 2.5 mg and ONGLYZA 5 mg (13.3% and 14.6%) versus placebo (10.1%). The incidence of confirmed hypoglycemia in this trial, defined as symptoms of hypoglycemia accompanied by a fingerstick glucose value of ≤50 mg/dL, was 2.4% and 0.8% for ONGLYZA 2.5 mg and ONGLYZA 5 mg and 0.7% for placebo [ see Warnings and Precautions (5.3) ]. The incidence of reported hypoglycemia for ONGLYZA 2.5 mg and ONGLYZA 5 mg versus placebo given as monotherapy was 4% and 5.6% versus 4.1%, respectively, 7.8% and 5.8% versus 5% given as add-on therapy to metformin HCl, and 4.1% and 2.7% versus 3.8% given as add-on therapy to TZD. The incidence of reported hypoglycemia was 3.4% in treatment-naive patients given ONGLYZA 5 mg plus metformin HCl and 4% in patients given metformin HCl alone. In the active-controlled trial comparing add-on therapy with ONGLYZA 5 mg to glipizide in patients inadequately controlled on metformin HCl alone, the incidence of reported hypoglycemia was 3% (19 events in 13 patients) with ONGLYZA 5 mg versus 36.3% (750 events in 156 patients) with glipizide. Confirmed symptomatic hypoglycemia (accompanying fingerstick blood glucose ≤50 mg/dL) was reported in none of the ONGLYZA-treated patients and in 35 glipizide-treated patients (8.1%) (p<0.0001). In the add-on to insulin trial, the overall incidence of reported hypoglycemia was 18.4% for ONGLYZA 5 mg and 19.9% for placebo. However, the incidence of confirmed symptomatic hypoglycemia (accompanying fingerstick blood glucose ≤50 mg/dL) was higher with ONGLYZA 5 mg (5.3%) versus placebo (3.3%). In the add-on to metformin HCl plus sulfonylurea trial, the overall incidence of reported hypoglycemia was 10.1% for ONGLYZA 5 mg and 6.3% for placebo. Confirmed hypoglycemia was reported in 1.6% of the ONGLYZA-treated patients and in none of the placebo-treated patients [ see Warnings and Precautions (5.3) ]. Hypersensitivity Reactions Hypersensitivity reactions, such as urticaria and facial edema in the 5-trial pooled analysis up to Week 24 were reported in 1.5%, 1.5%, and 0.4% of patients who received ONGLYZA 2.5 mg, ONGLYZA 5 mg, and placebo, respectively. None of these events in patients who received ONGLYZA required hospitalization or were reported as life-threatening by the investigators. One ONGLYZA-treated patient in this pooled analysis discontinued due to generalized urticaria and facial edema. Renal Impairment In the SAVOR trial, adverse reactions related to renal impairment, including laboratory changes (i.e., doubling of serum creatinine compared with baseline and serum creatinine >6 mg/dL), were reported in 5.8% (483/8280) of ONGLYZA-treated patients and 5.1% (422/8212) of placebo-treated patients. The most frequently reported adverse reactions included renal impairment (2.1% vs. 1.9%), acute renal failure (1.4% vs. 1.2%), and renal failure (0.8% vs. 0.9%), in the ONGLYZA versus placebo groups, respectively. From baseline to the end of treatment, there was a mean decrease in eGFR of 2.5 mL/min/1.73 m 2 for ONGLYZA-treated patients and a mean decrease of 2.4 mL/min/1.73 m 2 for placebo-treated patients. More patients randomized to ONGLYZA (421/5227, 8.1%) compared to patients randomized to placebo (344/5073, 6.8%) had downward shifts in eGFR from >50 mL/min/1.73 m 2 (i.e., normal or mild renal impairment) to ≤50 mL/min/1.73 m 2 (i.e., moderate or severe renal impairment). The proportions of patients with renal adverse reactions increased with worsening baseline renal function and increased age, regardless of treatment assignment. Infections In the unblinded, controlled, clinical trial database for ONGLYZA to date, there have been 6 (0.12%) reports of tuberculosis among the 4959 ONGLYZA-treated patients (1.1 per 1000 patient-years) compared to no reports of tuberculosis among the 2868 comparator-treated patients. Two of these six cases were confirmed with laboratory testing. The remaining cases had limited information or had presumptive diagnoses of tuberculosis. None of the six cases occurred in the United States or in Western Europe. One case occurred in Canada in a patient originally from Indonesia who had recently visited Indonesia. The duration of treatment with ONGLYZA until report of tuberculosis ranged from 144 to 929 days. Post-treatment lymphocyte counts were consistently within the reference range for four cases. One patient had lymphopenia prior to initiation of ONGLYZA that remained stable throughout ONGLYZA treatment. The final patient had an isolated lymphocyte count below normal approximately four months prior to the report of tuberculosis. There have been no spontaneous reports of tuberculosis associated with ONGLYZA use. Causality has not been estimated and there are too few cases to date to determine whether tuberculosis is related to ONGLYZA use. There has been one case of a potential opportunistic infection in the unblinded, controlled clinical trial database to date in an ONGLYZA-treated patient who developed suspected foodborne fatal salmonella sepsis after approximately 600 days of ONGLYZA therapy. There have been no spontaneous reports of opportunistic infections associated with ONGLYZA use. Vital Signs No clinically meaningful changes in vital signs have been observed in patients treated with ONGLYZA. Laboratory Tests Absolute Lymphocyte Counts There was a dose-related mean decrease in absolute lymphocyte count observed with ONGLYZA. From a baseline mean absolute lymphocyte count of approximately 2200 cells/microL, mean decreases of approximately 100 and 120 cells/microL with ONGLYZA 5 mg and 10 mg, respectively, relative to placebo were observed at 24 weeks in a pooled analysis of five placebo-controlled clinical trials. Similar effects were observed when ONGLYZA 5 mg was given in initial combination with metformin HCl compared to metformin HCl alone. There was no difference observed for ONGLYZA 2.5 mg relative to placebo. The proportion of patients who were reported to have a lymphocyte count ≤750 cells/microL was 0.5%, 1.5%, 1.4%, and 0.4% in the ONGLYZA 2.5 mg, 5 mg, 10 mg, and placebo groups, respectively. In most patients, recurrence was not observed with repeated exposure to ONGLYZA although some patients had recurrent decreases upon rechallenge that led to discontinuation of ONGLYZA. The decreases in lymphocyte count were not associated with clinically relevant adverse reactions. The 10 mg dosage is not an approved dosage. In the SAVOR trial mean decreases of approximately 84 cells/microL with ONGLYZA relative to placebo was observed. The proportion of patients who experienced a decrease in lymphocyte counts to a count of ≤750 cells/microL was 1.6% (136/8280) and 1.0% (78/8212) on ONGLYZA and placebo, respectively. The clinical significance of this decrease in lymphocyte count relative to placebo is not known. When clinically indicated, such as in settings of unusual or prolonged infection, lymphocyte count should be measured. The effect of ONGLYZA on lymphocyte counts in patients with lymphocyte abnormalities (e.g., human immunodeficiency virus) is unknown. 6.2 Postmarketing Experience Additional adverse reactions have been identified during post-approval use of ONGLYZA. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. • Gastrointestinal Disorders: Pancreatitis • Immune System Disorders: Hypersensitivity reactions including anaphylaxis, angioedema, and exfoliative skin conditions • Musculoskeletal and Connective Tissue Disorders: Rhabdomyolysis, Severe and disabling arthralgia • Skin and Subcutaneous Tissue Disorders: Bullous pemphigoid

• Strong CYP3A4/5 inhibitors (e.g., ketoconazole): Coadministration with ONGLYZA significantly increases saxagliptin concentrations. Limit ONGLYZA dosage to 2.5 mg once daily when coadministered with a strong CYP3A4/5 inhibitor. (7.1) 7.1 Strong Inhibitors of CYP3A4/5 Enzymes 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). The dosage of ONGLYZA should be limited to 2.5 mg when coadministered with a strong CYP3A4/5 inhibitor [ see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ]. 7.2 Insulin or Insulin Secretagogues Insulin and insulin secretagogues are known to cause hypoglycemia. Concomitant use of ONGLYZA with insulin or an insulin secretagogue may require lower dosages of insulin or the insulin secretagogue to reduce the risk of hypoglycemia [ see Warnings and Precautions (5.3) ].
