Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis : Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue dapagliflozin and saxagliptin if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. Pancreatitis: If pancreatitis is suspected, promptly discontinue dapagliflozin and saxagliptin. Heart Failure: Consider risks and benefits of dapagliflozin and saxagliptin in patients who have known risk factors for heart failure. Monitor patients for signs and symptoms. Volume Depletion: Before initiating dapagliflozin and saxagliptin, assess volume status and renal function in the elderly, patients with renal impairment or low systolic blood pressure, and in patients on diuretics. Monitor for signs and symptoms during therapy. Urosepsis and Pyelonephritis: Evaluate for signs and symptoms of urinary tract infections and treat promptly, if indicated. Hypoglycemia: Consider lowering the dose of insulin secretagogue or insulin to reduce the risk of hypoglycemia when initiating dapagliflozin and saxagliptin. Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene): Serious, life-threatening cases have occurred in both females and males. Assess patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise. If suspected, institute prompt treatment. Hypersensitivity Reactions : There have been postmarketing reports of serious hypersensitivity reactions in patients treated with saxagliptin, such as anaphylaxis, angioedema, and exfoliative skin conditions. Promptly discontinue dapagliflozin and saxagliptin, assess for other potential causes, institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes. Genital Mycotic Infections: Monitor and treat if indicated. Arthralgia: Severe and disabling arthralgia has been reported in patients taking DPP-4 inhibitors. Consider as a possible cause for severe joint pain and discontinue drug if appropriate. Bullous Pemphigoid: There have been postmarketing reports of bullous pemphigoid requiring hospitalization in patients taking DPP-4 inhibitors. Tell patients to report development of blisters or erosions. If bullous pemphigoid is suspected, discontinue dapagliflozin and saxagliptin. 5.1 Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis In patients with type 1 diabetes mellitus, dapagliflozin, a component of dapagliflozin and saxagliptin, significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond the background rate. In placebo-controlled trials of patients with type 1 diabetes mellitus, the risk of ketoacidosis was markedly increased in patients who received sodium-glucose cotransporter 2 (SGLT2) inhibitors compared to patients who received placebo. Dapagliflozin and saxagliptin is not indicated for glycemic control in patients with type 1 diabetes mellitus. Type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are also risk factors for ketoacidosis. There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes mellitus using SGLT2 inhibitors, including dapagliflozin. Precipitating conditions for diabetic ketoacidosis or other ketoacidosis include under-insulinization due to insulin dose reduction or missed insulin doses, acute febrile illness, reduced caloric intake, ketogenic diet, surgery, volume depletion, and alcohol abuse. Signs and symptoms are consistent with dehydration and severe metabolic acidosis and include nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. Blood glucose levels at presentation may be below those typically expected for diabetic ketoacidosis (e.g., less than 250 mg/dL). Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing dapagliflozin and saxagliptin ; however, there have been postmarketing reports of ketoacidosis and/or glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Consider ketone monitoring in patients at risk for ketoacidosis if indicated by the clinical situation. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue dapagliflozin and saxagliptin, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting dapagliflozin and saxagliptin. Withhold dapagliflozin and saxagliptin, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume dapagliflozin and saxagliptin when the patient is clinically stable and has resumed oral intake . Educate all patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue dapagliflozin and saxagliptin and seek medical attention immediately if signs and symptoms occur

Pancreatitis There have been postmarketing reports of acute pancreatitis in patients taking saxagliptin. In a cardiovascular outcomes trial enrolling participants with established atherosclerotic cardiovascular disease (ASCVD) or multiple risk factors for ASCVD (SAVOR trial), cases of definite acute pancreatitis were confirmed in 17 of 8240 (0.2%) patients receiving saxagliptin compared to 9 of 8173 (0.1%) receiving placebo. Pre-existing risk factors for pancreatitis were identified in 88% (15/17) of those patients receiving saxagliptin and in 100% (9/9) of those patients receiving placebo. After initiation of dapagliflozin and saxagliptin, observe patients for signs and symptoms of pancreatitis. If pancreatitis is suspected, promptly discontinue dapagliflozin and saxagliptin and initiate appropriate management. It is unknown whether patients with a history of pancreatitis are at increased risk for the development of pancreatitis while using dapagliflozin and saxagliptin

Heart Failure In a cardiovascular outcomes trial enrolling participants with established ASCVD or multiple risk factors for ASCVD (SAVOR trial), more patients randomized to saxagliptin (289/8280, 3.5%) were hospitalized for heart failure compared to patients randomized to placebo (228/8212, 2.8%). In a time-to-first-event analysis the risk of hospitalization for heart failure was higher in the saxagliptin group (estimated Hazard Ratio: 1.27; 95% CI: 1.07, 1.51). Subjects with a prior history of heart failure and subjects with renal impairment had a higher risk for hospitalization for heart failure, irrespective of treatment assignment. Consider the risks and benefits of dapagliflozin and saxagliptin prior to initiating treatment in patients at a higher risk of heart failure. Observe patients for signs and symptoms of heart failure during therapy. Advise patients of the characteristic symptoms of heart failure and to immediately report such symptoms. If heart failure develops, evaluate and manage according to current standards of care and consider discontinuation of dapagliflozin and saxagliptin

Volume Depletion Dapagliflozin can cause intravascular volume depletion which may sometimes manifest as symptomatic hypotension or acute transient changes in creatinine. There have been postmarketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients with type 2 diabetes mellitus receiving SGLT2 inhibitors, including dapagliflozin. Patients with impaired renal function (eGFR <60 mL/min/1.73 m 2 ), elderly patients, or patients on loop diuretics may be at increased risk for volume depletion or hypotension. Before initiating dapagliflozin and saxagliptin in patients with one or more of these characteristics, assess volume status and renal function. Dapagliflozin and saxagliptin is contraindicated in patients with an eGFR <45 mL/min/1.73 m 2 . Monitor for signs and symptoms of hypotension, and renal function after initiating therapy

Urosepsis and Pyelonephritis Serious urinary tract infections including urosepsis and pyelonephritis requiring hospitalization have been reported in patients receiving SGLT2 inhibitors, including dapagliflozin. Treatment with SGLT2 inhibitors increases the risk for urinary tract infections.Evaluate patients for signs and symptoms of urinary tract infections and treat promptly, if indicated [ see ADVERSE REACTIONS]

Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues Insulin and insulin secretagogues, such as sulfonylureas, are known to cause hypoglycemia. Both dapagliflozin and saxagliptin can individually increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue. Therefore, a lower dose of insulin or insulin secretagogue may be required to reduce the risk of hypoglycemia when these agents are used in combination with dapagliflozin and saxagliptin [ see ADVERSE REACTIONS]

Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene) Reports of necrotizing fasciitis of the perineum (Fournier’s Gangrene), a rare but serious and life-threatening necrotizing infection requiring urgent surgical intervention, have been identified in postmarketing surveillance in patients with diabetes mellitus receiving SGLT2 inhibitors, including dapagliflozin. Cases have been reported in both females and males. Serious outcomes have included hospitalization, multiple surgeries, and death. Patients treated with dapagliflozin and saxagliptin presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, should be assessed for necrotizing fasciitis. If suspected, start treatment immediately with broad-spectrum antibiotics and, if necessary, surgical debridement. Discontinue dapagliflozin and saxagliptin, closely monitor blood glucose levels, and provide appropriate alternative therapy for glycemic control

Hypersensitivity Reactions There have been postmarketing reports of serious hypersensitivity reactions in patients treated with saxagliptin. These reactions include anaphylactic reactions, angioedema, and exfoliative skin conditions. Onset of these reactions occurred within the first 3 months after initiation of treatment with saxagliptin, with some reports occurring after the first dose. If a serious hypersensitivity reaction is suspected, discontinue dapagliflozin and saxagliptin, treat per standard of care, and monitor until signs and symptoms are resolved. Assess for other potential causes for the event. Institute alternative treatment for diabetes. Use caution in a patient with a history of angioedema to another dipeptidyl peptidase-4 (DPP-4) inhibitor because it is unknown whether such patients will be predisposed to angioedema with saxagliptin

Genital Mycotic Infections Dapagliflozin increases the risks of genital mycotic infections. Patients with a history of genital mycotic infections were more likely to develop genital mycotic infections [ see ADVERSE REACTIONS]. Monitor and treat appropriately

Severe and Disabling Arthralgia There have been postmarketing reports of severe and disabling arthralgia in patients taking DPP-4 inhibitors. The time to onset of symptoms following initiation of drug therapy varied from one day to years. Patients experienced relief of symptoms upon discontinuation of the medication. A subset of patients experienced a recurrence of symptoms restarting the same drug or a different DPP-4 inhibitor. Consider DPP-4 inhibitors as a possible cause for severe joint pain and discontinue drug if appropriate [ see ADVERSE REACTIONS]

Bullous Pemphigoid Postmarketing cases of bullous pemphigoid requiring hospitalization have been reported with DPP-4 inhibitor use. In reported cases, patients typically recovered with topical or systemic immunosuppressive treatment and discontinuation of the DPP-4 inhibitor. Tell patients to report development of blisters or erosions while receiving dapagliflozin and saxagliptin. If bullous pemphigoid is suspected, dapagliflozin and saxagliptin should be discontinued and referral to a dermatologist should be considered for diagnosis and appropriate treatment.

Table 3 : Clinically Relevant Interactions with Dapagliflozin and Saxagliptin 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 dapagliflozin and saxagliptin with strong cytochrome P450 3A4/5 inhibitors . Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when dapagliflozin and saxagliptin is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) . 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 dapagliflozin and saxagliptin 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. Strong CYP3A4/5 Inhibitors (e.g., Ketoconazole): Do not coadminister dapagliflozin and saxagliptin with strong cytochrome P450 3A4/5 inhibitors. See full prescribing information for additional drug interactions and information on interference of dapagliflozin and saxagliptin with laboratory tests.
